The risk surveillance of schistosomiasis in Yunnan, 2021 / 中国热带医学

@#Abstract: Objective　To evaluate the potential transmission risk of schistosomiasis in Yunnan Province, and to provide strategic basis for the prevention and control. Methods　Based on the prevalence of schistosomiasis, the social and environmental factors that may lead to the epidemic, 1-3 villages from 3 provincial-level and 15 county-level counties (cities and districts) were selected as the evaluated villages in 2021. The risk of schistosomiasis spread was analyzed comprehensively by consulting, reviewing and collecting routine surveillance data of schistosomiasis in the villages, combined with snail and wild feces survey. The risk level was evaluated for the positive snails, positive wild feces, resident infection, average density of live snails and snail frame occurrence rate. Results　Totally 7 snail counties schistosomiasis transmission was blocked of 18 epidemic counties and the rest were eliminated counties. A total of 152 447 snail frames were investigated and 3 043 frames with snails, 15 895 snails were captured and included 15 727 live snails in the 32 evaluated villages. The total area of snail was 58.87 hm2 and the area of reoccurrence was 34.19 hm2 with snail frame occurrence rate of 2.00% and average density of live snails 0.103 2/0.11 m2, and no positive snails were found by loop-mediated isothermal amplification (LAMP) assay. A total of 1 374 wild feces were collected in 27 evaluated villages of 14 epidemic counties, mainly from cattle, dogs, sheep, equine animals, pigs and so on, all of which were negative. According to the risk assessment of epidemic spread, Yongle Village and Yongsheng Village in Eryuan County, Zhiming Village in Chuxiong City were Ⅱ risk, and the rest were Ⅲ risk. Conclusions　Although the risk of transmission is low in Yunnan Province, the risk of transmission and spread still exists. It is necessary to strengthen the risk monitoring, control of snail and effective management of livestock to prevent the rebound of the epidemic.

Identification of antler powder components based on DNA barcoding technology / 药学学报

In order to authenticate the components of antler powder in the market, DNA barcoding technology coupled with cloning method were used. Cytochrome c oxidase subunit I (COI) sequences were obtained according to the DNA barcoding standard operation procedure (SOP). For antler powder with possible mixed components, the cloning method was used to get each COI sequence. 65 COI sequences were successfully obtained from commercial antler powders via sequencing PCR products. The results indicates that only 38% of these samples were derived from Cervus nippon Temminck or Cervus elaphus Linnaeus which is recorded in the 2010 edition of "Chinese Pharmacopoeia", while 62% of them were derived from other species. Rangifer tarandus Linnaeus was the most frequent species among the adulterants. Further analysis showed that some samples collected from different regions, companies and prices, contained adulterants. Analysis of 36 COI sequences obtained by the cloning method showed that C. elaphus and C. nippon were main components. In addition, some samples were marked clearly as antler powder on the label, however, C. elaphus or R. tarandus were their main components. In summary, DNA barcoding can accurately and efficiently distinguish the exact content in the commercial antler powder, which provides a new technique to ensure clinical safety and improve quality control of Chinese traditional medicine

A Successful Resuscitation of a Young Patient with Persistent Life Threatening Ventricular Fibrillation during a Minor Surgical Procedure.

Aims: A discussion about the treatment options for cardiac arrest due to cocaine toxicity. Presentation of Case: This is a case report of a young man who underwent general anesthesia for a urologic procedure. He suffered a ventricular fibrillation arrest and required over an hour of Advanced Cardiac Life Support (ACLS). Team Strategies & Tools to Enhance Performance and Patient Safety (TeamSTEPPS) techniques were utilized. Within one hour from the initiation of the dysrhythmia he received femoral vessel cannulation in preparation for extracorporeal membrane oxygenation (ECMO). The hypothermia protocol was instituted early for brain protection. The patient completely recovered with no neurological or cardiovascular sequelae from this life threatening cardiac arrest. Upon further investigation, it was discovered that cocaine was consumed one day prior to surgery. Discussion: The use of cocaine is associated with multiple cardiovascular complications including ventricular fibrillation which was the probable etiology of this patient’s dysrhythmia. Recent studies elicited that there are underlying anatomic substrate alterations and changes in the molecular structure when cocaine is used. Cocaine stabilizes membranes in the nervous and myocardial tissue by antagonizing sodium and potassium channels. Multiple interventions were utilized which resulted in a successful resuscitation. Conclusion: The implementation of ACLS, ECMO, hypothermic brain protection and team training all aided in the complete neurologic recovery in this patient.

Estradiol Profiles During the Luteal Phase in Patients Undergoing IVF-ET Cycles / 现代生物医学进展

Objective: To investigate the predictive value of serum E2 in early diagnosis of pregnancy through IVF-ET(in vitro fertilization-embryo transfer). Methods: Sixty-two patients (75 cycles involved) undergoing IVF-ET cycles, whose infertility was attributed to uterine tube or male factors, were enrolled. Luteal phase serum E2 was detected every other day after extraction of oocytes with micro-particle enzyme immunoassay. Results: The level of serum E2 declined progressively after extraction of oocytes in both pregnant and non-pregnant cycles, while it showed no significant difference on 2, 4, 6, 8 days after extraction of oocytes. In pregnant cycles following IVF-ET, serum E2 achieved the nadir on day 10 and then increased gradually. The differences of serum E2 levels in pregnant and non-pregnant cycles were detectable from day 10 after extraction of oocytes (816.4+ 537.6 vs. 189.5±69.3 pg/ml) (P＜0.05). In non-pregnant cycles, E2 on day 10 was significantly lower than that on day 8 ( 189.5+ 69.3 vs. 989.2+581.5 pg/ml) (P＜0.05). Conclusions: We concluded that the level of E2 on day 8 and 10 consecutively after extraction of oocytes may have predictive value in diagnosing early pregnancy. Ascension of serum E2 level of pregnant patients on day 10 forebodes the success of pregnancy, or else the failure of pregnancy.
