Objective To investigate the clinical efficacy of Shangke Huangshui medicated gauze in the treatment of small-area deep second-degree burn wounds with fire-heat injuring fluid type.Methods Sixty patients who were diagnosed as small-area deep second-degree burn wounds of fire-heat injuring fluid type in Foshan Hospital of Traditional Chinese Medicine from January 2024 to July 2024,were selected as the research objects.The patients were randomly divided into trial group and control group by random number table method,with 30 cases in each group.The trial group was treated with external application of Shangke Huangshui medicated gauze,and the control group was treated with external application of Silver Sulfadiazine Cream.The treatment lasted for 21 days,and then the patients were followed up for 7 days.The changes of Visual Analogue Scale(VAS)score of wound pain,and serum levels of C-reactive protein(CRP),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)in the two groups were observed before and after treatment.The wound healing rate,wound healing time,bacterial infection of the wound,and adverse reactions were compared between the two groups.Results(1)During the treatment,there was no fell-off case in the trial group while there was one patient falling off from the control group.Eventually,a total of 59 patients were included in the statistical analysis,including 30 in the trial group and 29 in the control group.(2)On day 14 and 21 of treatment,the wound healing rates of the two groups were significantly higher than those on day 7 of treatment(P＜0.05),and wound healing rates in the trial group on the day 14 and 21 of treatment were significantly superior to those of the control group(P＜0.05).(3)The time for the complete healing of wound in the trial group was(22.07±2.30)days,which was significantly shorter than that of the control group[(27.07±4.10)days],and the difference was statistically significant(P＜0.05).(4)After 7,14 and 21 days of treatment,the VAS scores of wound pain in the two groups were lowered compared with those before treatment(P＜0.05),and the VAS scores in the trial group were significantly lower than those in the control group(P＜0.05).(5)On day 7 of treatment,the levels of serum CRP,IL-6 and TNF-α in the two groups were lowered compared with those before treatment(P＜0.05),and the levels in the trial group were significantly lower than those in the control group(P＜0.05).(6)On day 7 of treatment,the positive rate of bacterial culture for wound discharge in the trial group was 6.67%(2/30),which was significantly lower than 27.59%(8/29)in the control group,and the difference was statistically significant(P＜0.05).(7)There were no serious adverse events or adverse reactions occurring in the two groups during the trial.Conclusion Shangke Huangshui medicated gauze can accelerate the healing of burn wounds,shorten the wound healing time,reduce the wound infection rate and the level of serum inflammatory factors,and has fewer adverse reactions with high safety.

OBJECTIVETo explore the effect of warming needling pretreatment for endometrial receptivity before frozen-thawed embryo transfer (FET).

METHODSFifty-six repeatedly embryo transfer (ET) failure patients with ultrasound showing follicular phase endometrium of C type, hysteroscopy examination presenting endometritis were randomly assigned into an observation group (25 cases) and a control group (31 cases). The patients in the observation group three months before ET were treated with antibiotics in the menstrual period, warming needle (once a day) at Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Zhongji (CV 3), Zigong (EX-CA 1), Liangu (ST 34), Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39) after menstruation until the ovulation stopped, and oral administration of progesterone was applied after ovulation. The patients in the control group three months before ET were treated with antibiotics in the menstrual period, and oral administration of progesterone was applied after ovulation. Continuous three menstrual periods were carried out for the both groups. The changes of endometrial thickness, type and endometrial blood flow and the outcome of FET were observed.

RESULTSEndometrial morphology and blood flow were improved after treatment in the two groups (all<0.01), with better results in the observation group (both<0.01). The embryo transplantation rate and pregnancy rate in the observation group were higher than those in the control group (both<0.01), and the early abortion rate decreased (<0.01).

CONCLUSIONSWarm needling may improve endometrial receptivity, embryo transplantation rate and pregnancy rate and decrease early abortion rate by regulating endometrial morphology and blood flow.

Eight mouse hybridoma cell lines which stably secreted monoclonal antibodies ( McAbs ) against human prostate-specific antigen-α1-antichymotrypsin complex ( PSA-ACT ) were obtained through hybridoma technique. After purification, the immunological characters of 8 McAbs were identified and classified by epitopes analysis through indirect enzyme-linked immunosorbent assay ( ELISA) . A pair of McAbs was chosen from above 8 McAbs, based on which a highly sensitive, simple and rapid chemiluminescence enzyme immunoassay ( CLEIA) was developed for determination of PSA-ACT in human serums using the lumino-H2 O2 reaction catalyzed by horseradish peroxidase ( HRP) as the chemiluminescence system. Several experiment factors such as coating buffer, coating concentration, dilution ratio of PSA-ACT-HRP complex, incubation time, immunoreaction protocol and chemiluminescence reaction time were optimized. The results showed that the linear range of the proposed method for PSA-ACT determination was 0-40 ng/mL (R2=0. 9943), with the detection limit of 0. 53 ng/mL. The inter-assay relative standard deviations (RSDs) were 4. 6%-6. 6%, and intra-assay RSDs were 5 . 7%-8 . 0%. The recoveries of PSA-ACT at three spiked levels in serum samples were 95. 4%-104. 2%. The proposed method exhibited a cross-reactivity of 0. 6% with free-PSA. The proposed method is stable, sensitive, rapid and simple, and provides a foundation for the development of PSA-ACT CLEIA kit and shows great value in clinical auxiliary diagnosis of prostate cancer.
