Objective:To evaluate the clinical efficacy of Cai's gynecological nourishing kidney therapy for patients with diminished ovarian reserve (DOR).Methods:A randomly controlled trail was conducted. A total of 63 patients with DOR who were treated in the gynecology outpatient clinic of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine affiliated to Shanghai University of Traditional Chinese Medicine from September 2020 to January 2022 were set as observation subjects, and were divided into control group ( n=31) and observation group ( n=32) according to the random number table method. The patients in the control group were treated with Femoston, and the patients in the observation group were treated with Cai's gynecological nourishing kidney therapy on the basis of Femoston treatment. Both groups were treated for 3 menstrual cycles. Both antral follicle count (AFC) was performed by vaginal ultrasound, serum levels of TGF-β1, IL-1β, IL-2, IL-6 and IL-21 were detected by ELISA, and serum levels of FSH, LH, E2, anti-Müllerian hormone (AMH) and MDA were detected by biochemical methods. The TCM syndrome score was used to evaluate the severity of symptoms, and the menstrual score was used to evaluate the abnormal menstruation. Clinical efficacy was evaluated. Results:The total effective rate was 87.50% (28/32) in the observation group and 58.06% (18/31) in the control group, with statistical significance ( χ2=8.42, P=0.004). After treatment, the AFC in the observation group (3.93±2.32 vs. 2.21±2.18, t=3.03) was higher than that of the control group ( P<0.01). After treatment, the serum FSH level of the observation group [10.05 (8.35, 21.48) IU/L vs. 20.60 (8.00, 43.30) IU/L, Z=2.18] was lower than that of the control group ( P<0.05), and the level of AMH [0.19 (0.03, 0.47) μg/L vs. 0.02 (0.01, 0.24) μg/L, Z=-1.54] in the observation group was higher than that of the control group ( P<0.05). The serum levels of TGF-β1 [(68.27±11.76) ng/L vs. (55.33±13.03) ng/L, t=4.14] and IL-1β [(58.00±7.53) ng/L vs. (52.31±8.06) ng/L, t=2.89] in the observation group were higher than those in the control group, and the levels of IL-6 [(33.26±7.45) ng/L vs. (40.69±11.69) ng/L, t=3.02], the level of IL-21 [(118.37±15.56) ng/L vs. (140.43±25.51) ng/L, t=-4.04] was lower than that of the control group ( P<0.01). Conclusions:Cai's gynecological nourishing kidney therapy combined with Fenmaotong can effectively increase the AFC of DOR patients and improve clinical efficacy. Its mechanism of action may be related to reducing serum FSH and LH levels and increasing E2 levels.

Objective:To explore the clinical effect of application of a posterior femoral perforator flap (PFPF) relayed an adjacent flap of recipient site in reconstruction of the recurrent pressure sores in sacrococcygeal region.Methods:Retrospective observation method was used in this study. From December 2019 to May 2023, 13 patients with recurrent pressure sores in sacrococcygeal region were admitted in the Department of Burns and Plastic Surgery of the 910th Hospital of Joint Service Support Unit of PLA. The patients were 8 males and 5 females who aged 42-69 years old. All the pressure sores were in Grade Ⅲ-Ⅳ. Eight patients had pressure sores for a second time and 5 for a third time. After preoperative preparations, the surgical treatment was planned in 2 stages. In the first stage, the pressure sores were thoroughly debrided, and the wounds after debridement were at 5.0 cm×6.0 cm-15.0 cm×9.0 cm in size. After debridement, the wounds were covered by VSD for 7 days. Flap reconstruction of the wounds of pressure sores were performed in the second stage surgery. According to the location and size of the wounds and the remaining normal skin tissue around the wounds, the adjacent flaps were taken to reconstruct the wounds of sacrococcygeal pressure sore. PFPFs were employed to reconstruct the donor site wounds left by the adjacent flap. The sizes of the adjacent flap were 6.0 cm×7.0 cm-16.0 cm×9.5 cm, and the PFPFs were 9.0 cm×8.0 cm-18.0 cm×10.0 cm in size. PFPF was rotated in a manner of propeller. The donor sites of PFPF were directly sutured. After surgery, survival of the adjacent flaps and PFPFs, the wound healing in the donor sites as well as the healing time were observed. The appearance, texture and recurrence of pressure sores of the flap reconstruction sites were observed at outpatient clinic, via WeChat reviews or telephone interviews up to January 2024.Results:Twenty-six flaps of 13 patients survived after surgery, inclusive of 1 patient with the adjacent flap partially split due to turn-over and transport of the patient after surgery, and healed after a re-suture under local anaesthesia. In addition, 1 patient had effusion under the adjacent flap and 1 patient had partial split under the PFPF, both of which healed after dressing changes, with an overall healing time of 16-30 days. Postoperative follow-ups lasted for 6-12 months. The flaps had good appearance, soft texture, no surface rupture and without the recurrence of a pressure sore.Conclusion:Treatment of recurrent pressure sores in sacrococcygeal region by reconstructive surgery with PFPF relaid adjacent flap can achieve the effects of closure of wound, high survival rate of flap and good wound healing. It does not require skin grafting for the donor site at posterior thigh and achieves a good and long-term therapeutic effects under the circumstance that only a small amount of normal skin tissue is left on the buttocks.

Objective To investigate the effects of long non-coding RNA(lncRNA)SNHG15 on lipopolysaccharide(LPS)-induced injury of human alveolar epithelial cells and the underlying molecular mechanism.Methods A549 cells were treated with LPS to construct a neonatal acute respiratory distress syndrome(NRDS)cell model.A549 cells were divided into Control group,LPS group,LPS+si-NC group,LPS+si-lncRNA SNHG15 group,LPS+miR-NC group,LPS+miR-942-5p group,LPS+si-lncRNA SNHG15+anti-miR-NC group and LPS+si-lncRNA SNHG15+anti-miR-942-5p group.Real-time fluorescence quantitative PCR(qRT-PCR)was used to detect the expression levels of lncRNA SNHG15 and miR-942-5p.Flow cytometry and Western blot were conducted to detect cell apoptosis.ELISA was used to detect the expression levels of interleukin-6(IL-6),in-terleukin-1β(IL-1β),and tumor necrosis factor-α(TNF-α).Dual-luciferase reporter assay was used to identify the targeting rela-tionship between lncRNA SNHG15 and miR-942-5p.Results Compared with the Control group,lncRNA SNHG15 expression,apoptosis rate,and levels of Bax,IL-6,IL-1β and TNF-α were increased in the LPS group,while miR-942-5p expression and Bcl-2 protein level were decreased(all P＜0.05).After knockdown of lncRNA SNHG15 or overexpression of miR-942-5p,cell apop-tosis rate and levels of Bax,IL-6,IL-1β and TNF-α were decreased,while Bcl-2 level was increased(all P＜0.05).lncRNA SNHG15 targeted miR-942-5p,and downregulation of miR-942-5p reversed the effect of lncRNA SNHG15 knockdown on LPS-induced A549 cell injury(all P＜0.05).Conclusion Silencing of lncRNA SNHG15 alleviates LPS-induced A549 cell injury by upregulation of miR-942-5p.

Objective To explore the prognostic impact and clinical application value of therapeutic plasma exchange(TPE)intervention timing and liver injury periodization in patients with exertional heat stroke(EHS).Methods Data of 127 EHS patients from the First Medical Center of the General Hospital of the People′s Liberation Army from January 2011 to December 2023 were collected,then divided into the death group and the survival group based on therapeutic outcomes and into 5 stages according to the dynamic changes of ALT,AST,TBIL and DBIL.According to propensity score matching analysis,11 patients in the survival group and 12 patients in the death group were included in the statistical analysis,and 20 of them were treated with TPE.The changes in indicators and clinical outcomes before and after TPE were observed,in order to evaluate the impact of intervention timing on prognosis.Results Among the 23 patients,14 had no liver injury or could progress to the repair phase,resulting in 3 deaths(with the mortality rate of 21.43%),while 9 patients failed to pro-gress to the repair phase,resulting in 9 deaths(with the mortality rate of 100%),with significant differences(P＜0.05).The mortality rate of the first TPE intervention before the third stage of liver injury was 23.08%(3/13),while that of interven-tion after reaching or exceeding the third stage was 85.71%(6/7),and the difference was statistically significant(P＜0.05).Conclusion TPE should be executed actively in EHS patients combined with liver injury before the third phase to lock its pathological and physiological processes,thereby improving prognosis and reducing mortality.

Objective To review the occurrence of allergic reactions during therapeutic plasma exchange(TPE)and to explore the risk factors of TPE allergic reactions.Methods The clinical data of 929 patients treated with TPE using plasma components by the Department of Transfusion Medicine in our medical center from 2018 to 2023 were collected.The influen-cing factors of allergic reactions were analyzed by univariate analysis,and the independent risk factors of allergic reactions were analyzed by logistic multivariate regression analysis.Results A total of 4 071 TPEs were performed in 929 patients.A-mong them,198 patients(21.31%)experienced 349 times(8.57%)of allergic reactions,with the incidence of gradeⅠ,Ⅱ and Ⅲ allergic reactions of 16.33%,81.38%and 2.29%,respectively,and no deaths.The univariate analysis showed that the patient′s age,allergy history,diagnosis of immune-related diseases,ICU admission,plasma consumption,total blood volume,maximum blood flow rate and combined use of albumin were related to the occurrence of allergic reactions(P＜0.05).Multivariate regression analysis showed that young patients,a history of allergy,immune-related diseases and non-ICU patients were prone to allergic reactions in TPE,but the treatment options of TPE such as substitute fluid category,plasma consumption and blood flow rate were not related to the occurrence of allergic reactions.Conclusion There are sig-nificant individual differences in the occurrence of allergic reactions for TPE,and young age,history of allergies,immune-related diseases and non-ICU patients are risk factors for allergic reactions in TPE.Identifying patients with risk factors be-fore TPE treatment and giving corresponding preventive measures can reduce the incidence of allergic reactions.

ObjectiveTo investigate effect of Maxing Shigantang and supplemented Guominjian decoction on symptoms and levels of inflammatory cytokines in induced sputum of children with cough variant asthma （CVA）. MethodA total of 118 CVA children who were treated in our hospital from January 2020 to January 2021 were enrolled and randomized into the control group and the observation group with the random number table method. Control group received routine western medicine and the observation group was treated by routine western medicine， Maxing Shigantang， and supplemented Guominjian decoction. In the one-month follow-up， the scores of cough and accompanying symptoms， levels of inflammatory cytokines ［interleukin-10 （IL-10）， interleukin-5 （IL-5）， tumor necrosis factor-α （TNF-α）， neutrophil， eosinophil］ in induced sputum， pulmonary function parameters ［forced vital capacity （FVC）， forced expiratory volume in one second （FEV₁）， FEV₁/FVC］， and treatment outcomes were compared between the two groups. Moreover， the frequency of acute asthma attacks during the three-month follow-up was also compared. ResultNo cases dropped out from this study. After treatment， the scores of cough and accompanying symptoms were decreased in both groups （P<0.05） and were lower in observation group than in control group （P<0.05）. After treatment， FVC， FEV₁， and FEV₁/FVC were raised in both groups and were higher in observation group than in control group （P<0.05）. The increase in the level of IL-10 along with the decrease in levels of IL-5， TNF-α， neutrophil， and eosinophil in induced sputum was found in both groups after treatment （P<0.05）， and observation group had higher level of IL-10 and lower levels of IL-5， TNF-α， neutrophil， and eosinophil than the control group （P<0.05）. The effective rate was 86.44% （51/59） in observation group， which was higher than the 69.49% （41/59） in control group （χ²=4.933， P<0.05）. No serious adverse reaction occurred in either group. The frequency of acute asthma attacks during the three-month follow-up was （1.09±0.18） in observation group， which was lower than the （2.83±049） in the control group （P<0.05）. ConclusionRoutine western medicine combined with Maxing Shigantang and supplemented Guominjian decoction can effectively and safely alleviate the airway inflammatory responses， control the clinical symptoms， improve pulmonary function， and reduce the frequency of acute recurrence in the treatment of CVA children.

【Objective】 To evaluate common laboratory items in a large-dose blood loss model in vitro using thromboelastogram (TEG), to provide a reasonable infusion solution for clinical massive transfusions. 【Methods】 On March 2nd, 2017, eight healthy blood donors who participated in voluntary blood donation in the Department of Blood Transfusion Medicine of the First Medical Center of the PLA General Hospital were selected to undergo phlebotomy, and an in vitro dilution model of massive blood loss was established based on the previous research, namely Model 1 (M1, given massive transfusion protocol) and Model 2 (M2, given packed red blood cells and plasma) were established. Then blood routine, routine coagulation function, clotting factor activity, TEG of each model were tested. 【Results】 The platelet count in the M1 model was 61.00±10.24 (×10⁹/L), and reduced to 28.83±10.36(×10⁹/L) in M2 (P<0.01). The MA value (mm) of two groups detected by TEG was 29.35±2.37 vs 20.53± 2.76 (P<0.01). In M1 and M2 model, The activities of primary clotting factors respectively decreased to about 40% and 30% to original in M1 and M2. The R value of TEG prolonged to (6.32±0.85) min and (7.27±0.63) min respectively, still within the normal range(baseline 4.97±1.04). The fibrinogen concentration in the M1 and M2 model decreased to (1.10±0.08) g/L and (0.81±0.10) g/L(P<0.01), which had the same variation tendency to Alpha angle of TEG (25.65±4.95 vs 16.63±3.94, P>0.05). 【Conclusion】 MTP with blood components supplemented such as platelet and cryoprecipitate in time has effectively improved the Plt and Fib in vitro large-dose blood loss/transfusion model.
