OBJECTIVE: The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture. METHODS: Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve. RESULTS: Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats. CONCLUSION Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

Objective:To explore the protective effect of labor analgesia on pelvic floor muscle function of primipara after vaginal delivery.Methods:A total of 140 cases of primipara with vaginal delivery admitted to the Affiliated Hospital of Jining Medical College from March to August 2022 were selected retrospectively, and they were divided into control group (routine delivery) and observation group (painless delivery) according to the intention of delivery, each group with 70 cases. Labor pain, pelvic floor muscle function score and pelvic floor muscle status at 6 weeks postpartum, Female Sexual Function Scale (FSFI) score at 3 months postpartum and reported postpartum symptoms were compared between the two groups.Results:The scores of Visual Analogue Scale (VAS) at immediately after gastric antral empting, after drinking carbohydrates (5, 30, 60, 120 min) and at full opening of uterine orifice in the observation group were lower than those in control group, there were statistical differences ( P<0.05). At 6 weeks postpartum, the maximum muscle voltage of pelvic floor muscle and the average muscle voltage of continuous contraction of pelvic floor muscle for 60 s in the observation group were higher than those in control group: (20.97 ± 2.64) μV vs. (17.31 ± 2.48) μV, (17.33 ± 3.01) μV vs. (13.42 ± 2.77) μV; the mobility of bladder neck and the hiatus area of levator anal muscle in resting state in the observation group were lower than those in the control group: (27.15 ± 3.55) mm vs. (31.05 ± 4.75) mm, (9.97 ± 2.12)cm 2 vs. (11.57 ± 2.84) cm 2, there were statistical differences ( P<0.05). At 6 weeks postpartum, the scores of static pre-stage, static post-stage, type Ⅰ muscle fiber, type Ⅱ muscle fiber and total scores in the observation group were higher than those in the control group: (67.21 ± 12.54) scores vs. (54.17 ± 10.84) scores, (69.12 ± 14.11) scores vs. (56.47 ± 11.24) scores, (63.54 ± 11.45) scores vs. (50.97 ± 10.74) scores, (57.15 ± 8.15) scores vs. (49.76 ± 6.44) scores, (64.25 ± 12.14) scores vs. (57.84 ± 20.57) scores, there were statistical differences ( P<0.05). At 6 weeks postpartum, the scores of FSFI in the observation group were higher than those in the control group ( P<0.05). The rate of urine leakage, fever and mattress sweat reported in the observation group were lower than those in the control group: 22.86%(16/70) vs. 40.00%(28/70), 15.71%(11/70) vs. 30.00%(21/70), 30.00%(21/70) vs. 47.14%(33/70), there were statistical differences ( χ2 = 4.77, 4.05, 4.34, P<0.05). Conclusions:Labor analgesia can effectively shorten labor process, relieve labor pain and protect pelvic floor muscle function during vaginal labor in primipara.

OBJECTIVE: This study assesses the impact of smoke-free legislation on the incidence rate for acute myocardial infarction (AMI) and stroke in Shenzhen. METHODS: Data on ischemic ( n = 72,945) and hemorrhagic ( n = 18,659) stroke and AMI ( n = 17,431) incidence covering about 12 million people in Shenzhen from 2012 to 2016 were used. Immediate and gradual changes in incidence rates were analyzed using segmented Poisson regression. RESULTS: Following the smoke-free legislation, a 9% (95% CI: 3%-15%) immediate reduction was observed in AMI incidence, especially in men (8%, 95% CI: 1%-14%) and in those aged 65 years and older (17%, 95% CI: 9%-25%). The gradual annual benefits were observed only in hemorrhagic and ischemic stroke incidence, with a 7% (95% CI: 2%-11%) and 6% (95% CI: 4%-8%) decrease per year, respectively. This health effect extended gradually to the 50-64 age group. In addition, neither the immediate nor gradual decrease in stroke and AMI incidence rates did not show statistical significance among the 35-49 age group ( P > 0.05). CONCLUSION Smoke-free legislation was enforced well in Shenzhen, which would generate good experiences for other cities to enact and enforce smoke-free laws. This study also provided more evidence of the health benefits of smoke-free laws on stroke and AMI.

Objective: To investigate the clinicopathological features and possible mechanisms of burned-out testicular germ cell tumors. Methods: The clinical and imaging data, histology and immunophenotypic characteristics of three cases of burned-out testicular germ cell tumors diagnosed at the Ruijin Hospital, Medical College of the Shanghai Jiaotong University, from 2016 to 2020 were retrospectively analyzed. The relevant literature was reviewed. Results: The mean age of the three patients was 32 years. Case 1 had an elevated preoperative alpha-fetoprotein level (810.18 μg/L) and underwent "radical pancreaticoduodenectomy and retroperitoneal lesion resection" for a retroperitoneal mass. Postoperative pathology showed embryonal carcinoma, which needed to exclude gonadal metastasis. Color Doppler ultrasound showed a solid mass of the right testis, with hypoechoic lesion and scattered calcification in some areas. Case 2 was a "right supraclavicular lymph node biopsy specimen." Chest X-ray showed multiple metastases in both lungs. The biopsy showed metastatic embryonic carcinoma and bilateral testicular color Doppler ultrasound revealed abnormal calcifications in the right testicle. Case 3 showed a cystic mass of the right testis with calcification and solid areas. All 3 patients underwent radical right orchiectomy. Grossly, borders of the testicular scar areas were well defined. Cross sectioning of the tumors showed a gray-brown cut surface and single focus or multiple foci of the tumor. The tumor maximum diameter was 0.6-1.5 cm. Microscopically, lymphocytes, plasma cells infiltration, tubular hyalinization, clustered vascular hyperplasia and hemosiderin laden macrophages were found in the scar. Atrophic and sclerotic seminiferous tubules, proliferation of clustered Leydig cells and small or coarse granular calcifications in seminiferous tubules were present around the scar. Seminoma and germ cell neoplasia in situ were seen in case 1, germ cell neoplasia in situ was seen in case 2 and germ cells with atypical hyperplasia were seen in case 3. Immunohistochemistry showed that embryonic carcinoma expressed SALL4, CKpan(AE1/AE3) and CD30, seminoma and germ cell tumor in situ expressed OCT3/4, SALL4 and CD117, and spermatogenic cells with atypical hyperplasia expressed CD99 and SALL4. The Ki-67 positive index was about 20%, while OCT3/4 and CD117 were both negative. Conclusions: Burned-out testicular germ cell tumors are rare. The possibility of gonad testicular metastasis should be considered first for extragonadal germ cell tumor. If fibrous scar is found in testis, it must be determined whether it is a burned-out testicular germ cell tumor. The burned-out mechanisms may be related to the microenvironment of tumor immune-mediated and local ischemic injury.

BACKGROUND: Polycystic ovary syndrome (PCOS) is the primary cause of anovulatory infertility, bringing serious harm to women's physical and mental health. Acupuncture may be an effective treatment for PCOS. However, systematic reviews (SRs) on the efficacy and safety of acupuncture for PCOS have reported inconsistent results, and the quality of these studies has not been adequately assessed. OBJECTIVE: To summarize and evaluate the current evidence on the efficacy and safety of acupuncture for PCOS, as well as to assess the quality and risks of bias of the available SRs. SEARCH STRATEGY: Nine electronic databases (Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, Chinese National Knowledge Infrastructure, Wanfang Data, Chongqing VIP Chinese Science and Technology Periodical Database, and China Biology Medicine disc) were searched from their establishment to July 27, 2022. Based on the principle of combining subject words with text words, the search strategy was constructed around search terms for "acupuncture," "polycystic ovary syndrome," and "systematic review." INCLUSION CRITERIA: SRs of randomized controlled trials that explored the efficacy and (or) safety of acupuncture for treating patients with PCOS were included. DATA EXTRACTION AND ANALYSIS: Two authors independently extracted study data according to a predesigned form. Tools for evaluating the methodological quality, risk of bias, reporting quality, and confidence in study outcomes, including A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), Risk of Bias in Systematic Reviews (ROBIS), Preferred Reporting Items for Systematic Reviews and Meta-analyses for Acupuncture (PRISMA-A), and the Grading of Recommendations Assessment, Development and Evaluation (GRADE), were used to score the included SRs. RESULTS: A total of 885 studies were retrieved, and 11 eligible SRs were finally included in this review. The methodological quality of 2 SRs (18.18%) was low, while the other 9 SRs (81.82%) were scored as extremely low. Four SRs (36.36%) were considered to be of low risk of bias. As for reporting quality, the reporting completeness of 9 SRs (81.82%) was more than 70%. Concerning the confidence in study results, 2 study results were considered to have a high quality of evidence (3.13%), 14 (21.88%) a "moderate" quality, 28 (43.75%) a "low" quality, and 20 (31.24%) considered a "very low" quality. Descriptive analyses suggested that combining acupuncture with other medicines can effectively improve the clinical pregnancy rate (CPR) and ovulation rate, and reduce luteinizing hormone/follicle-stimulating hormone ratio, homeostasis model assessment of insulin resistance, and body mass index (BMI). When compared with medicine alone, acupuncture alone also can improve CPR. Further, when compared with no intervention, acupuncture had a better effect in promoting the recovery of menstrual cycle and reducing BMI. Acupuncture was reported to cause no adverse events or some adverse events without serious harm. CONCLUSION The efficacy and safety of acupuncture for PCOS remains uncertain due to the limitations and inconsistencies of current evidence. More high-quality studies are needed to support the use of acupuncture in PCOS.

Objective:To summarize the clinical data of anti-factor H antibody-associated atypical hemolytic uremic syndrome (aHUS) in children, and analyze the risk factors for disease recurrence and poor prognosis.Methods:A prospective cohort study was conducted on 52 children with anti-factor H antibody-associated aHUS in Beijing Children′s Hospital, Capital Medical University from November 2011 to November 2021.Patient information about the genetic background, clinical and renal pathological characteristics, treatment, and prognosis were collected.Then, the disease recurrence and prognosis were analyzed using the survival curve and Cox regression model. Results:In 52 children, there were 33 males and 19 females.The average age of onset for aHUS was 2.4-12.8 years, and 92.3%(48/52) of the children developed symptoms at the age of 4-12 years.The copy numbers of complement factor-H-related 1 (CFHR1) and complement factor-H-related 3 (CFHR3) genes were calculated in 42 children.Among the 42 cases, 18 cases (42.9%) had CFHR1 homozygous deletion, and 83.3% (15/18) of them also had CFHR3 homozygous deletion.All the patients were given plasma therapy.Besides, 76.9% (40/52) of the children were treated with immunosuppressive therapy (steroid and/or immunosuppressant) at the first onset of the disease.About 86.5%(45/52 cases) of the patients received immunosuppressive therapy in the course of disease, and the immunosuppressive treatment lasted for 6-20 months in total.The median follow-up time was 58 (28, 91) months.Among 52 patients, only 12 patients (23.1%) suffered disease recurrence.The relapse-free survival rate in children with CFHR1 homozygous deletion was significantly lower than that in children with non-homozygous deletion ( χ2=4.700, P=0.030). The relapse-free survival rate in children with CFHR1 and CFHR3 homozygous deletions was also significantly lower than that in other children ( χ2=4.181, P=0.041). At the end of the follow-up, 73.1%(38/52) of the children had normal renal function and no persistent proteinuria or hypertension.23.1%(12/52 cases) of the children had persistent proteinuria and/or hypertension.One child had Stage 3-4 chronic kidney disease, and 1 child was dialysis dependent. Conclusions:Anti-factor H antibody-associated aHUS is prone to occur in children aged between 4-12 years old, who respond well to plasma therapy and immunosuppressive therapy.Children with anti-factor H antibody-associated aHUS and CFHR1 and CFHR3 homozygous deletions have a high recurrence rate.Treatment with immunosuppressive therapy and assessment of the copy number of CFHR1 and CFHR3 genes in the early stage of the disease are important for preventing disease recurrence and improving prognosis.

OBJECTIVE: This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province. METHODS: We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed. RESULTS: The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α ^3.7/αα (50.23%) and β ^IVS-II-654/β ^N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively. CONCLUSION Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.
