Objective To find out about the utilization of health resources by rural pulic health centers in Hubei Province in the Ninth Five-Year Plan period so as to provide primary information for the better use of rural health resources. Methods The issues of Hubei Health Statistics and Hubei Almanac in 1990 and from 1996 to 2000 were collected and statistial analyses were conducted by means of the spss software. Results In the Ninth Five-Year Plan period, the human resources and fixed assets of rural public health centers in Hubei Province kept increasing whereas the volume of services dropped year by year. The reduction in the average number of outpatient visits and discharged patients per annum was respectively 4. 42% and 4. 09%. The efficiency of the health personnel in delivering medical services has been decreasing, with the average number of patients treated by each person per annum, the annual number of beds utilized, and the annual number of discharged patients in 2000 dropping respectively by 27.54% , 30.22% and 26.36% , as compared with 1996. The annual ratio of bed utilization was around 30% and the number of bed turnovers was about 20 times, evidencing, moreover, a tendency of going down. Conclusion The input of health resources in the rural public health centers in Hubei Province in the Ninth Five-Year Plan period increased while the rate of utilization dropped. It is suggested that integrated management in the rural areas be adopted, better utilization of health resources made, reform of the public health centers deepened, and internal management improved; greater stress be laid on improving the quality of rural health personnel; and the rural cooperative medical and health system be perfected.

Objective To investigate the influence of atorvastatin in methylation and expression level of Bcl-2 in human umbilical endothelial cells(HUVECs)treated with homocysteine(Hcy)and to expound potential mechanism of atorvastatin resisting arteriosclerosis.Methods After HUVECs were treated with 0, 2, 4, 8, 16, and 32 mmol·L-1 Hcy for 48 h,MTT was used to measure the inhibitory rates of HUVECs and the half inhibitory concentration (IC50 ). According to the experimental results, the HUVECs cultured in vitro were divided into control group (0.00 mmol · L-1 Hcy ), Hcy group (9.00 mmol·L-1 Hcy ), and atorvastatin group (9.00 mmol·L-1 Hcy+1×10-3 mmol·L-1 atorvastatin).After treated for 48 h,flow cytometry was used to detect the apoptotic rate of cells, the mRNA expression of Bcl-2 was analyzed by fluorescence quantitative PCR,the protein expression of Bcl-2 was detected by Western blotting method, and the methylation level of Bcl-2 promoter region was determined by nest touch-down PCR combined with methylation specific PCR (MSP ). Results Compared with control group,the apoptotic rate of HUVECs in Hcy group was increased(P<0.01),the mRNA and protein expression levels of Bcl-2 were significantly decreased(P<0.01),and the Bcl-2 promoter region methylation level was also decreased(P<0.01).Compared with Hcy group,the apoptotic rate of HUVECs in atorvastatin group was decreased(P<0.01),the mRNA and protein expression levels of Bcl-2 gene were increased (P<0.05), and the Bcl-2 promoter region methylation level was also increased (P<0.05). Conclusion Atorvastatin can prevent the apoptosis of HUVECs induced by Hcy through regulating Bcl-2 methylation.

Objective:To investigate whether different type of chronic prostatitis could have a deleterious effect on semen quality. Methods: Forty-nine patients diagnosed as suffering from chronic prostatitis were included and di-vided into groups according to the presence of infection and/or cellular autoimmune response against prostate anti-gens. Healthy normal individuals were included as controls. Measurements for sperm concentration, motility, morphology, prostate and seminal vesicle markers, antisperm antibodies, white blood cells and pro-inflammatory cytokines were performed accordingly. Results:The most severe abnormalities were found in patients with no evi-dent infection and an autoimmune response against prostate antigens. Moreover, significantly increased levels of pro-inflammatory cytokines were detected in seminal plasma from these patients. Conclusions: This study shows that chronic prostatitis patients with cellular autoimmune response to prostate antigens present important altera-tions in their semen quality parameters and may affect male fertility.

Objective:To investigate the correlation between the muscle mass loss and severe postoperative pulmonary complications(PPC)in elderly patients with non-small cell lung cancer(NSCLC).Methods:Elderly patients with NSCLC undergoing lobectomy at the Lung Cancer Institute and the Department of Thoracic Surgery of Guangdong Provincial People's Hospital were recruited from Feb.2019 to Dec.2019.Data of the body composition, lung function, respiratory muscle strength test, cardiopulmonary exercise test were collected before operation.All patients were grouped into two groups: with versus without severe PPC at 30 d after operation.The differences of the above parameters were compared between the two groups.A multiple logistic regression analysis was used to analyze the risk factors for severe PPC.Results:In this study, 120 elderly NSCLC patients undergoing lobectomy were recruited, All evaluations were completed in 113 patients(aged 68.13±7.01 years)in whom, 21(18.58%, 21/113)patients had serious PPC.Compared with patients without PPC, patients with severe PPC had a lower appendicular skeletal muscle mass index(ASMI)(5.67±0.90 kg/m 2vs.7.71±1.40 kg/m 2, t=3.900, P=0.001), a lower forced expiratory volume in 1 second(FEV 1)(1.85±0.40 L vs.2.12±0.57 L, t=2.412, P=0.027), a lower maximal mid-expiratory flow(MMF)(1.40±0.69 L/s vs.2.11±1.09 L/s, t=2.502, P=0.021), a lower maximum inspiratory pressure(Pimax)(55.13±32.52 cmH 2O vs.64.71±20.60, t=0.778, P=0.047, 1 cmH 2O=0.098 kPa), a lower maximal oxygen consumption(Vo 2max)(1.14±0.41 L/min vs.1.40±0.34 L/min, t=0.779, P=0.046), a lower peak O 2 consumption(Vo 2max@kg)(20.00±1.91 L·min -1·kg -1vs.22.33±2.37 L·min -1·kg -1, t=0.813, P=0.041). Multiple logistic regression analysis showed that in addition to FEV 1( OR=2.824, 95% CI: 1.127-5.158, P=0.001)and Vo 2max@kg( OR=3.149, 95%CI: 1.829-6.592, P<0.001), ASMI was also an independent risk factor for serious PPC( OR=1.919, 95% CI: 1.604-3.466, P=0.006), in which the best cut-off value was 6.295 kg/m 2, the sensitivity and specificity were 0.816 and 0.818 respectively, and the area under the receiver operating characteristic(ROC)curve(AUC)was 0.887(95% CI: 0.793-0.981, P<0.0001). Conclusions:Muscle mass loss can increase the risk for the occurrence of severe PPC within 30 days after lobectomy in elderly patients with NSCLC.

[Objective]To present a case of complete androgen insensitivity syndrome (CAIS) coexisting with Müllerian duct remnants (MDR) and to review previous reports in the literature to enhance the understanding of the clinical manifestations and pathophysiology of CAIS.[Methods]The study aimed to diagnose complete androgen insensitivity syndrome (CAIS) by conducting physical examinations,chromosomal analysis,whole exome sequencing,laboratory tests including follicle-stimulating hormone (FSH),luteinizing hormone (LH),total testosterone,estradiol,anti-Müllerian hormone (AMH),inhibin B,dehydroepiandrosterone sulfate (DHEAS),androstenedione,17-hydroxyprogesterone,and imaging studies such as pelvic ultrasound and pelvic magnetic resonance imaging (MRI). Laparoscopy revealed the presence of Müllerian duct structures. Additionally,the study reviewed similar cases of CAIS combined with Müllerian duct remnants reported in the literature.[Results]The child presented with female phenotype,elevated levels of FSH,LH,and testosterone. Pelvic MRI showed bilateral cryptorchidism without visible uterus or fallopian tubes. The chromosomal karyotype was 46,XY,and whole exome sequencing identified a pathogenic variant in the androgen receptor (AR) gene,c.2359C>T (p.Arg787*). No abnormalities were found in the AMH and AMHR2 gene tests. Laparoscopic exploration revealed underdeveloped testes and an underdeveloped uterus. Pathology showed the presence of fallopian tube-like structures next to the testicles. A total of 11 cases with genetically confirmed diagnosis of CAIS coexisting with MDR were retrieved from the database. The findings suggest that the initial clinical presentation,biochemical data,and gonadal pathology of CAIS with MDR are similar to those without MDR.[Conclusion]The study reports a patient with CAIS coexisting with MDR,which broadens the clinical spectrum of CAIS and provides a perspective for basic research on Müllerian duct regression that is independent of the AMH-AMHR2 signaling pathway.
