Abstract: Objective　To investigate the diagnostic efficacy of rifampin-resistant real-time fluorescent quantitative nucleic acid amplification detection technology (GeneXpert MTB/RIF) in bronchoalveolar lavage fluid (BALF) combined with peripheral blood tuberculosis infection T cell spot test (T-SPOT) and tuberculosis antibody (TB-Ab) in smear-negative pulmonary tuberculosis. Methods　The clinical data of 114 cases of clinically diagnosed smear-negative pulmonary tuberculosis, 80 cases of non-tuberculous pulmonary diseases and 22 cases of smear-positive pulmonary tuberculosis in our hospital from January 2019 to January 2021 were retrospectively analyzed. The detection results of peripheral blood T-SPOT, TB-Ab and BALF GeneXpert in the three groups were analyzed. The sensitivity, specificity, negative predictive value, positive predictive value, false negative rate, false positive rate and Youden index of the three detection methods were compared. The differences in the positive detection rate of smear-negative pulmonary tuberculosis between the separate detection and the combined detection of the three methods were compared. The receiver operating characteristic curve (ROC) was performed to calculate the area under the curve (AUC). Results　The sensitivity of BALF GeneXpert and peripheral blood T-SPOT and TB-Ab was 66.91%, 80.88% and 90.44%, respectively. The specificity was 98.75%, 73.75% and 41.25%, respectively; the diagnostic coincidence rates were 78.70%, 78.24% and 72.22%, respectively, which were higher than 70.00%. In the smear-negative pulmonary tuberculosis group, the positive detection rates of these three methods in the smear-negative pulmonary tuberculosis group were 63.15%, 79.82% and 90.35%, respectively, and the differences were statistically significant compared with those in the non-tuberculosis pulmonary disease group (all P<0.01). The positive detection rate of the three combined methods in the smear-negative pulmonary tuberculosis group was 96.49 %, which was significantly higher than that of TB-GeneXpert method and T-SPOT, and the differences were statistically significant (χ2=37.283, P<0.01; χ2=13.612, P<0.01); the Youden index of combined detection was significantly higher than that of single detection, and the AUC of combined detection was 0.977, which was significantly higher than that of single detection. Conclusion　BALF GeneXpert combined with peripheral blood T-SPOT and TB-Ab can significantly improve the diagnostic rate of bacterial-negative pulmonary tuberculosis, providing a strong basis for guiding clinical treatment.

Objective: To explore the points selection pattern of acupuncture for sleep apnea syndromes by data mining technique. Methods: Clinical literature about acupuncture therapy for sleep apnea syndromes was derived from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), PubMed and Science Direct between the time that databases were created and March 25th,2017. Relevant excel database was established and descriptive studies and association rules were analyzed. Results: The most frequently used point was Lianquan (CV 23) and the most frequently used meridian was the Stomach Meridian. The analysis of association rules showed that the clinical choice of acupuncture points was highly correlated, among which the combination of the highest degree of confidence and the highest degree of support was Shenmen (HT 7) and Sishencong (EX-HN 1); Lieque (LU 7), lianquan (CV 23) and Zhaohai (KI 6). Conclusion: Acupuncture treatment of sleep apnea syndromes has specific selection rules of points, providing certain references for clinical and scientific research.

To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) and TACE alone for hepatocellular carcinoma (HCC), Pubmed, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Datebases were searched for the randomized controlled trials (RCTs) and retrospective cohort studies from the establishment of the databases to January 2014. The bibliographies of the included studies were searched, too. After study selection, assessment, data collection and analysis were undertaken, we performed this meta-analysis by using the RevMan5.2 software. Seventeen studies involving 1116 patients met the inclusion criteria with 530 treated with RFA-plus-TACE and 586 with TACE alone. The results of meta-analysis showed that the combination of TACE and RFA was obviously associated with higher 1-, 2-, and 3-year overall survival rates (OR1-year=3.98, 95% CI 2.87-5.51, P<0.00001; OR2-year=3.03, 95% CI 2.10-4.38, P<0.00001; OR3-year=7.02, 95% CI 4.14-11.92, P<0.00001) than TACE alone. The tumor complete necrosis rate in patients treated with TACE and RFA was higher than that of TACE alone (OR=13.86, 95% CI 8.04-23.89, P<0.00001). And there was a significant difference in local recurrence rate between two different kinds of treatment (OR=0.24, 95%CI 0.14-0.44, P<0.00001). Additionally, combination of TACE and RFA was associated with higher complete tumor necrosis rates than TACE mono-therapy in the treatment of HCC. However, RFA plus TACE was found to be associated with a lower local recurrence rate than TACE monotherapy. TACE-plus-RFA treatment was associated with a higher response rate (RR) than the TACE-alone treatment (OR=3.90, 95% CI=2.37-6.42, P<0.00001). TACE-plus-RFA treatment did not differ from the TACE-alone treatment in terms of stable disease (SD) rate (OR=0.38, 95% CI=0.11-1.26, P=0.11). Meta-analyses showed that the combination of RFA and TACE was associated with a significantly lower progressive disease (PD) rate (OR=0.15, 95% CI=0.05-0.43, P=0.0005). The rate of AFP reducing or returning to normal in serum in RFA plus TACE group was obviously lower than TACE alone group (OR=4.62, 95% CI 2.56-8.34, P<0.00001). The effect of TACE plus RFA for HCC is better than TACE mono-therapy. The combined therapy can elevate the patients' overall survival rate, tumor necrosis rate and the rate of AFP reducing or returning to normal in serum and decrease local recurrence rate, PD rate compared with TACE alone.

Objective: To observe the clinical efficacy of deep electroacupuncture (EA) at Baliao points in treating stress urinary incontinence (SUI). Methods: A total of 60 female patients with SUI were divided into two groups according to the order of consultation, with 30 cases in each group. The control group was treated with pelvic floor muscle training. The treatment group was treated with deep EA at Baliao points [Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33) and Xialiao (BL 34)]. Results: The total effective rate was 93.3％ in the treatment group, versus 33.3％ in the control group, and the total effective rate of the treatment group was significantly higher than that of the control group (P<0.05). After treatment, the scores of international consultation on incontinence questionnaire-short form (ICIQ-SF) and the volume of urinary leakage in both groups were lower than those before treatment (all P<0.05), and the ICIQ-SF score and the volume of urinary leakage in the treatment group were lower than those in the control group (both P<0.05). Conclusion: Deep EA at Baliao points with long needles can improve the clinical symptoms in female patients with SUI, and it has a better curative effect than pelvic floor muscle training.

OBJECTIVETo investigate how network education can improve college students' knowledge on sexual and reproductive health in Ningbo city.

METHODSFrom December 2012 to June 2013, we conducted a questionnaire investigation among college students in Ningbo city about the effects of network education on their knowledge about sexual psychology, sexual physiology, sexual ethics, and reproductive health.

RESULTSA total of 7 362 college students accomplished the investigation, of whom 2 483 (42.1% males and 57.9% females) received network education, while the other 4 879 (24.1% males and 75.9% females) did not. Approximately 47.1% of the male and 28.0% of the female students acquired sexual and reproductive knowledge via network education. Reproductive health-related network education significantly enriched the students' knowledge about the reproductive system and sex, pubertal development, sexual physiology, conception and embryonic development, methods of contraception, sexual psychology, sexually transmitted diseases and their prevention, pregnancy care and eugenics, and environment- and occupation-related reproductive health (P < 0.01). It also remarkably improved their cognitive attitude towards reproductive health knowledge (P < 0.01). Those who received reproductive health-related network education showed a significantly higher rate of masturbation (P < 0.01) but markedly later time of the first masturbation (P < 0.01) than those who did not.

CONCLUSIONNetwork education can enhance the effect of reproductive health education among college students and improve their sexual experience and health.

OBJECTIVETo investigate the neurodevelopmental outcome of preterm infants who were discharged from neonatal intensive care unit (NICU) at 1 year of age and the impact factors contributing to the neurodevelopmental outcome and to study whether early intervention can improve the neurodevelopmental outcome in preterm infants.

METHODSEarly intervention guidance and follow-up visits were performed after the preterm infants discharged from NICU. The infants received the infant development test of Child Development Centre of China (CDCC) for neurological development at 1 year of age. The neurodevelopmental outcome was evaluated based on mental development index (MDI) and physical development index (PDI). MDI and PDI > 85 was defined as normal, MDI or PDI between 70 and 85 as critical and MDI or PDI < 70 as abnormal. Social-domestic and clinical factors related to neurological development were analyzed by ANOVA or chi-square test. Potential high risk factors were analyzed with logistic regression. To investigate the effects of intervention compliance on neurological development, the infants were classified into two groups according to different intervention compliances. The good compliance group included infants who received a through familial intervention for more than 4 days weekly (30 minutes daily) and consulted with physicians more than 5 times in 1 year. The infants who did not receive the interventions as the good compliance group served as the bad compliance group.

RESULTSThis study consisted of 210 infants, with a mean gestational age of 33.2 +/- 2.6 weeks and a mean birth weight of 1923.3 +/- 558.8 g. Normal, critical and abnormal neurological development occurred in 123 cases (58.6%), 61 cases (29.0%) and 26 cases (12.4%) respectively. Eighteen infants (8.6%) had mental lag and 9 (4.3%) had cerebral palsy (CP). The MDI and PDI scores of the good compliance group (111 cases) were 97.15 +/- 17.38 and 94.23 +/- 18.55 respectively, which were markedly higher than those of the bad compliance group (89.87 +/-18.92 and 87.20 +/-19.12; P < 0.05). The incidence of CP (3/111, 2.7%) in the good compliance group was lower than that of the bad compliance group (5/99, 6.1%) although there were no statistical differences. Parents' education level, multiple birth, serious intracranial hemorrhage and apnea were risk factors for adverse neurodevelopmental outcome.

CONCLUSIONSPreterm infants discharged from NICU are a high risk group of neurodevelopmental disablement. Early intervention can improve the neurodevelopmental outcome of perterm infants at high risk.

OBJECTIVETo analyze the clinical features of 128 acquired immunodeficiency syndrome (AIDS) patients infected through blood transmission who were coinfected with hepatitis B virus (HBV) and hepatitis C virus (HCV).

METHODSThe prevalence, liver functions, and some immunological profiles of 128 AIDS patients coinfected with HBV and HCV were retrospectively analyzed.

RESULTSAmong the 128 AIDS patients, 107 (83.6%) were coinfected with HCV, among which 40 (31.3%) patients had abnormal liver functions or liver damage and 15 (11.7%) patients experienced hepatitis symptoms. Three (2.3%) AIDS patients were singly coinfected with HBV, and all of them had abnormal liver functions and hepatitis symptoms. Seven (5.5%) patients were coinfected with HIV/HCV/HBV and none of them had abnormal liver functions or hepatitis symptoms. Eleven (8.6%) patients were only infected with HIV.

CONCLUSIONSThe prevalence of blood-transmitted HIV patients coinfected with HCV is higher than with HBV. The clinical outcomes of HIV coinfection with HCV and HBV are different.
