2.Effect of fluid resuscitation on hemodynamics and oxygen in severe trauma patients
Clinical Medicine of China 2008;24(12):1272-1274
Objective To observe the effect of fluid resuscitation on hemodynamies and oxygen in severe trauma patients. Methods Parameters of hemodynamic and oxygen metabolism in different fluid volume resuscita-tion in 24 severe trauma patients who were injured on abdominal were measured. Results By fluid resuscitation, as the systolic blood pressure was raised from 80~90 mm Hg(1 mm Hg=0.133 kPa) to 100~120 mm Hg,cardiac in-dex rose from (2.0±0.5 ) L/(min·m2) to (3.2±0.6) L/(min·m2) (P<0.05), systemic vascular resistance index rose from (1857.6±750.2) dyn·s/(cm5·m2) to (3741.5±862.1) dyn·s,/(cm5·m2) significantly (P<0.05). Meanwhile, oxygen delivery index rose from (301.1±74.1) ml/(min·m2) to (554.1±80.0) mL/(min·m2) (P<0.05), and oxygen consumption index also rose (99.7±51.4) mL/( min·m2) to (147.2± 60.1) mL/(min·m2) remarkably (P<0.05), the rate of oxygen expenditure decreased from (33.1±9.1) % to (26.6±8.0) % significantly (P<0.05). Conclusion Large volume resuscitation maybe benefit to the improve-ment of hemodynamics and oxygen metabolism in the emergency resuscitation.

Objective To investigate the status of clinical using of blood products in Shanghai area,clinicians' understanding on transfusion knowledge and consciousness of prevention of transfusion risk.Methods Two hundreds of clinicians who were randomly selected from level two and above hospitals of Shanghai were inquired by questionnaire.Data including understanding of transfusion techniques,prevention of transfusion risk,application of blood components and grasp of new techniques were collected and analyzed.Results Among all interviewed clinicians,those who realized the importance of transfusion on clinical work,who understood the basic contents of clinical guideline for transfusion issued by Ministry of Health People's Republic of China,and who had the basic knowledge of blood component products and transfusion applications account for 62%,60% and 81% respectively.But only 28% clinicians knew all the side effects,27.3% learned the new techniques of transfusion,including leukocyte reduced,virus elimination,clinical application of irradiation.This investigation also showed 97% clinicians would like to accept training of transfusion,68% thought they need more relevant information about prevention of transfusion risk.Conclusions Clinicians in Shanghai area had the basic knowledge of clinical guideline for transfusion,but some knowledge of transfusion were insufficient including blood components and their applications,side effects and new techniques of transfusion.Clinicians in Shanghai had active response for being trained on knowledge of transfusion.

Abstract: Malaria, an infectious disease caused by Plasmodium infection, is one of the most important public health problems worldwide. Artemisinin-based combination therapies (ACTs) are recommended by WHO as the first-line treatment for uncomplicated P. falciparum malaria in malaria-endemic areas. The application of artemisinin and its derivatives has played an integral role in reducing the global incidence of malaria. However, in recent years, the emergence and spread of artemisinin resistance has brought great challenges to global malaria control and elimination. At present, the mutation of K13 gene on chromosome 13 of Plasmodium falciparum is most closely related to artemisinin resistance, but in recent years, studies have shown that K13 cannot explain all artemisinin resistance. This article reviews the recent research progress in the field of artemisinin resistance in Plasmodium falciparum, including definition of artemisinin resistance, detection methods and molecular markers related to resistance. In addition, some of the issues discussed in this review remain controversial and require further study.
6. Effect of Bmal1 expression on radiotherapy sensitivity of nasopharyngeal carcinoma xenograft
Chinese Journal of Clinical Oncology 2020;47(1):12-17
Objective: To explore the effects of up- and down-regulation of circadian clock gene Bmal1 on the growth and radiation sensitivity of nasopharyngeal carcinoma after CNE1 xenograft in nude mice. Methods: We produced four groups of cells using lentiviral transfection: cells overexpressing CNE1 (CNE1OE), negative control in which there was no overexpression of CNE1 (OENC), cells with short hairpin RNAi (CNE1sh3), and RNAi negative cells (CNE1shNC). We investigated the expression of Bmal1 protein in the aforementioned groups with Western blot. After subcutaneously injecting the four groups of cells in nude mice, the size of the xenograft was measured. Subsequently, the xenografts were irradiated with 15 Gy at 6 MeV, and variation in the xenograft volume was recorded. mRNA and protein expression levels of Bmal1, p53, and p21 in the xenograft were measured with RT-PCR and Western blot, respectively. Results: The CNE1OE group highly expressed Bmal1 protein whereas the CNE1sh3 group was silenced by RNAi as shown with the Western blot, indicating successful transfection. The xenograft in the nude mice developed well. The CNE1OE xenograft volume was lower than that of the CNE1OENC xenograft, whereas the CNE1sh3 xenograft was larger than the CNE1shNC xenograft (P<0.05). CNE1OE, CNE1OENC, and CNE1shNC xenograft volumes shrank after being irradiated (t=4.32, 5.38, 5.16, respectively; P<0.05) and the effect was the highest in the CNE1OE group. However, there was almost no variation in xenograft volume in the CNE1sh3 group. The relative amounts of mRNA and protein of Bmal1, P53, and P21 were higher in the CNE1OE group than in the CNE1OENC group,while they were lower in the CNE1sh3 group compared to the CNE1shNC group (P<0.05). Conclusions: Overexpression of Bmal1 inhibited the growth of the CNE1 xenograft in nude mice and enhanced its radiation sensitivity whereas silencing the Bmal1 gene by RNAi promoted the growth of the xenograft and led to radiation resistance. We believe that Bmal1 overexpression leads to P53 and P21 overexpression, thereby inhibiting the growth of the xenograft.

Repetitive(repetitive extragenic palindromic,REP,and enterobaterial repetitive intergenic consensus,ERIC) sequences in conjunction with polymerase chain reaction technique(REP and ERIC PCR) were used to fingerprint the genomes of 27 isolates of indigenous soybean rhizobia from Xinjiang.The indigenous soybean rhizobia in Xinjiang can be clustered into relative genetic similarities of approximately 0.5,of which one group mainly includes all slow-growing rhizobia,another mainly includes all fast-growing stains. REP and ERIC PCR analysis demonstrate a substantial genetic variability within members of Xinjiang indigenous soybean rhizobial populations, which reveals that genetic similarities have certain geographical correlation, and isolates from the same site have relative higher similarities.The results show that REP and ERIC PCR analysis give effective means in genetic diversity and population structure analysis of soybean rhizobia.

Objective To discuss causes and corresponding prevention for groin pain occurred early after total hip arthroplasty(THA).Methods A retrospective study was done on 189 cases(193 hips)treated with THA including unilateral procedures in 185 hips and bilateral procedures in eight hips to analyze common causes for early groin pain.Results Groin pain was found in 9.3% hips(18/ 193)during hospital stay,including 1.6%(3 cases)with deep infection,1.6%(3 cases)with incision infection,1%(2 cases)with posterior dislocation,4.1%(8 cases)with leg lengthening and 1%(2 cases)with hematoma.Conclusions Despite of the numerous diagnostic alternatives available to the orthopedic surgeon,detailed history,careful physical examination,necessary laboratory and imaging stud- ies can contribute to a correct determination of causes for groin pain.Meanwhile,appropriate indication, accurate preoperative radiographic measurement,intraoperative standardized surgical procedures and per- fect rehabilitation are necessary to avoid complications.

Objective To establish an accurate method for determining the content of three components in Fufang Buwu Syrup. Methods TLC scanner was selected to detect three components with silica gel G thin layer plate. The sample was separated by using cyclohexane-ethyl acetate-methylenechloride-formic acid (3∶1∶1∶0.2),λS=300 nm. Results The linearity between peak area and ferulic acid was achieved in the range of 0.36-0.84μg, psoralen was achieved in the range of 0.12-0.28 μg, emodin was achieved in the range of 0.01-0.05 μg. The average recovery was 100.7%, 100.8%, 101.0%, and RSD was 1.26%, 1.44%, 1.86%, respectively. Conclusion The method is simple and accurate, which can be used for quality control of Fufang Buwu Syrup.
