L P He, L Wang
From the beginning of the 19th century to the Opium War, by taking the advantages of free entering and departing China, and to protect themselves, the foreign firms introduced vaccination technique into China. This is the beginning of the introduction of western medicine to China. After 1807, following the arrival of protestant missionaries, foreign firms became the stronghold for the missionaries to conceal their missionary status so as to propagate the principles of Christianity. With the aid of the business firms employee's legal identity, the missionaries started their activities of delivering western medicines and practices...

The emergence of new gene-editing technologies is profoundly transforming human therapeutics, agriculture, and industrial biotechnology. Advances in clustered regularly interspaced short palindromic repeats (CRISPR) have created a fertile environment for mass-scale manufacturing of cost-effective products ranging from basic research to translational medicine. In our analyses, we evaluated the patent landscape of gene-editing technologies and found that in comparison to earlier gene-editing techniques, CRISPR has gained significant traction and this has established dominance...

In this study, we identified and evaluated the genetic relationships among Cinnamomum plants, which are used in traditional medicine. We also attempted to monitor the distribution of traditional medicines derived from Cinnamomum cassia by using DNA barcoding and a species-specific DNA marker. Plants of the genus Cinnamomum, and in particular C. cassia, are commonly used as medicinal herbs in the form of Cinnamomi Ramulus, Cinnamomi Cortex, and Cassiae Cortex Interior. However, it is difficult to distinguish among different Cinnamomum species based on morphological features, and so to overcome this limitation, nucleotide sequences of the internal transcribed spacer (ITS) region of Cinnamomum DNA were determined and compared...

Since it was first introduced, the main goal of PET/CT has been to provide both PET and CT images with high clinical quality and to present them to radiologists and specialists in nuclear medicine as a fused, perfectly aligned image. The use of fused PET and CT images quickly became routine in clinical practice, showing the great potential of these hybrid scanners. Thanks to this success, manufacturers have gone beyond considering CT as a mere attenuation corrector for PET, concentrating instead on design high performance PET and CT scanners with more interesting features...

Combination products are therapeutic and diagnostic medical products that combine drugs, devices, and/or biological products with one another. Historically, biologics development involved identifying efficacious doses administered to patients intravenously or perhaps by a syringe. Until fairly recently, there has been limited focus on developing an accompanying medical device, such as a prefilled syringe or auto-injector, to enable easy and more efficient delivery. For the last several years, and looking forward, where there may be little to distinguish biologics medicines with relatively similar efficacy profiles, the biotechnology market is beginning to differentiate products by patient-focused, biologic-device based combination products...

Preventative health care of elasmobranchs is an important but understudied field of aquatic veterinary medicine. Evaluation of inflammation through the acute phase response is a valuable tool in health assessments. To better assess the health of bonnethead sharks ( Sphyrna tiburo ) under managed care, normal reference intervals of protein electrophoresis (EPH) and the acute phase proteins, C-reactive protein (CRP) and haptoglobin (HP), were established. Blood was collected from wild caught, captive raised bonnethead sharks housed at public aquaria...

Historically, biologic materials found in nature have been used for a wide variety of medicinal purposes, although their widespread use may be limited due to challenges in obtaining and properly preparing the material for safe clinical use. Amniotic membrane has long been recognized to possess unique properties favorable for healing. Dehydrated human amnion/chorion membrane allografts are commercially available for use in multiple sizes and configurations applicable for a variety of clinical settings and presentations...

In the context of requested decrease of antimicrobial use in veterinary medicine, our objective was to assess the impact of two doses of marbofloxacin administered on young bulls (YBs) and veal calves (VCs) treated for bovine respiratory disease, on the total population of Enterobacteriaceae in gut flora and on the emergence of resistant Enterobacteriaceae. In two independent experiments, 48 YBs from 6 commercial farms and 33 VCs previously colostrum deprived and exposed to cefquinome were randomly assigned to one of the three groups LOW, HIGH, and Control...

BACKGROUND: Medical faculties have a role in ensuring that their students are protected from undue commercial influence during their training, and are educated about professional-industry interactions. In North America, many medical faculties have introduced more stringent conflict of interest (COI) policies during the last decade. We asked whether similar steps had been taken in France. We hypothesized that such policies may have been introduced following a 2009-2010 drug safety scandal (benfluorex, Mediator) in which COIs in medicine received prominent press attention...

BACKGROUND: Health incapacitation is a serious threat to flight safety. Therefore, a study conducted 10 yr ago examined the incidents of ear-nose-throat (ENT) barotrauma and upper respiratory infection (URI) among commercial pilots and found that a large number continued to carry out their duties despite the risk of incapacitation. Now, 10 yr later, this new study examines if the attention to URIs has improved. METHOD: This study was conducted at the Danish Aeromedical Centre over the course of 1 yr with 463 valid respondents to a questionnaire on URIs and ENT barotrauma...

Dogs with a 4-bp deletion in the MDR1 (or ABCB1) gene show intolerance to certain drugs routinely used in veterinary medicine, such as ivermectin, vincristine, and doxorubicin. The mutation leads to a dysfunctional P-glycoprotein drug transporter, which results in drug accumulation in the brain and severe neurotoxicity. A rapid and accurate in-house test to determine the genotype of patients in cases of acute neurotoxic signs or in tumor patients is desirable. We describe a cost-effective detection method with simple technical equipment for veterinary practice...

Pulsatillae radix is a conventional traditional Chinese medicine (TCM) with common name Baitouweng, and has notable effects on inflammation and dysentery. Pulsatilla chinensis (Bge.) Regel is the only source plant of Baitouweng recorded in Chinese Pharmacopoeia, but its adulteration often occurs in the market that possibly affects medicinal efficacy and safety. We have established an internal transcribed spacer 2 (ITS2) barcode library based on 105 plant samples from 12 Pulsatilla species and 10 common adulterants...

BACKGROUND: Edible Bird's Nest (EBN) as a popular traditional Chinese medicine is believed to have health enhancing and antiviral activities against influenza A virus (IAV); however, the molecular mechanism behind therapeutic effects of EBN is not well characterized. METHODS: In this study, EBNs that underwent different enzymatic preparation were tested against IAV infected cells. 50% cytotoxic concentration (CC50) and 50% inhibitory concentration (IC50) of the EBNs against IAV strain A/Puerto Rico/8/1934(H1N1) were determined by HA and MTT assays...

Cancer has been treated with radiopharmaceuticals for 80 years. A recent NCRI report from the Clinical and Translational Radiotherapy Research Working Group (CTRad) reviews the current status of molecular radiotherapy (MRT) and has highlighted the barriers to, and the opportunities for increased research activities. The report recommends a number of actions to promote this field, which in the dawning age of personalised medicine and theragnostics is of increasing importance, particularly with the clinical introduction of a range of new commercial radiotherapeutics at costs in line with those seen for conventional chemotherapeutics...

The pharmaceutical industry plays an increasingly dominant role in healthcare, raising concerns about "conflicts of interest" (COI) on the part of the medical professionals who interact with the industry. However, there is considerable disagreement over the extent to which COI is a problem and how it should be managed. Participants in debates about COI have become entrenched in their views, which is both unproductive and deeply confusing for the majority of medical professionals trying to work in an increasingly commercialized environment...
