Objective To investigate the incidence of adverse pregnancy outcomes among women with syphilis in Zhejiang province during 2013-2014,and to explore the influence of anti?syphilis treatment on pregnancy outcomes. Methods A retrospective study was carried out according to the Information Management System for preventing mother?to?child transmission(PMTCT)of syphilis in Zhejiang province during 2013-2014. The incidence of adverse pregnancy outcomes was compared between women with syphilis and general women without syphilis, between treated and untreated women with syphilis, as well as between women with syphilis receiving and not receiving standard anti?syphilis treatment. The effects of anti?syphilis treatment and standard anti?syphilis treatment on pregnancy outcomes were analyzed. Results Data were collected from 3 985 women with syphilis and their children. Of these women, 12 had a stillbirth, and 3 973 a live birth. Totally, 3 210(80.55%)women received anti?syphilis treatment, 967(30.12%, 967/3 210) women received substandard treatment, and 775(19.45%)did not receive anti?syphilis treatment. Of the 3 985 fetuses or neonates born to women with syphilis, 45(1.13%)had abnormal clinical symptoms/signs. The incidence rates of low birth weight and early neonatal death were 7.00%(279/3 985) and 1.13%(45/3 985) respectively in fetuses or neonates born to women with syphilis, both significantly higher than those in fetuses or neonates born to general women without syphilis (3.18%[26 092/819494] and 0.13%[1 029/819 494], respectively, both P < 0.01). Among 775 untreated women with syphilis, the incidence rates of premature birth, low birth weight, early neonatal death, congenital syphilis and abnormal neonatal symptoms/signs were 15.61%(121/775), 10.84%(84/775), 2.45%(19/775), 3.48%(27/775)and 2.84%(22/775)respectively, all significantly higher than those in 3 210 women receiving anti?syphilis therapy (8.26%, 6.07%, 0.81%, 0.81% and 1.03%,respectively, all P < 0.01). Besides, the 967 women receiving substandard anti?syphilis treatment showed higher incidence rates of premature birth, low birth weight, early neonatal death, congenital syphilis and abnormal neonatal symptoms/signs than the 2 243 women receiving standard treatment (10.44%vs. 7.31%, 8.17%vs. 5.17%, 1.55%vs. 0.49%, 1.65%vs. 0.45%, 1.96%vs. 0.62%, respectively, all P<0.01). Conclusions The incidence of adverse pregnancy outcomes is high among women with syphilis in Zhejiang province during 2013-2014. Untreated and inadequately treated maternal syphilis is strongly associated with adverse pregnancy outcomes.

Objective To evaluate the clinical effect of posterior decompression, internal fixation and interlaminar fusion for the treatment of severe osteoporotic vertebral fracture and collapse complicated with spinal canal encroachment. Methods A retrospective study was carried out in 27 cases of severe osteoporotic vertebral fractures complicated with spinal canal encroachment. The patients were treated with posterior decompression, internal fixation and interlaminar fusion during the period from January 1, 2009 to December 31, 2014. All patients were given vertebral pedicle screw fixation after pedicle augmentation with bone cement. The pain scores of visual analogue scale(VAS), Oswestry Disability Index(ODI), Cobb angle , thoracolumbar Cobb angle and the recovery of neurological function(estimated by Frankel grading system) of the patients were compared beforeoperation, one week after operation and at the end of follow-up. The incidences of internal fixation failure, adjacent vertebral fracture and bone cement leakage also were recorded. Results The patients were followed up for an average of 27 months. The spinal canal occupation rate caused by fracture fragment of posterior vertebral wall was 27.41%~63.85%, with an average of(43.24 ± 10.61)%. Postoperative VAS pain scores, ODI, Cobb angle and thoracolumbar Cobb angle were statistically different from those before operation (P < 0.05). The correction rate for Cobb angle and thoracolumbar Cobb angle was (63.31 ± 23.47)%, (61.91 ± 17.54)%respectively. At the end of the follow-up, the correction loss rate for Cobb angle and the thoracolumbar Cobb angle was (15.38 ± 39.92)%, (21.79 ± 32.20)% respectively, the difference being insignificant compared with those one week after operation(P>0.05). In respect of Frankel grading of neurological function at the end of the follow-up, 6 cases were in grade D and 19 cases were in grade E, but the differences were insignificant compared with those before operation (P > 0.05). None of the patients had surgical site infection, screw looseness or breakage, or rod breakage during the follow-up period. There were 8 patients with asymptomatic bone cement leakage after operation. Vertebral compression fractures recurred in 5 patients, of which 2 had adjacent vertebral fractures and 3 had non -adjacent segment. Conclusion The therapy of posterior decompression, internal fixation and interlaminar fusion is effective for the treatment of severe osteoporotic vertebral fracture and collapse complicated with spinal canal encroachment by obviously relieving pain, improving the physiological function of the spine and stabilizing the spine.

OBJECTIVETo investigate the effects of obstructive sleep apnea-hypopnea syndrome (OSAHS) and age on sleep architecture and the therapeutic effects of continuous positive airway pressure (CPAP).
METHODSWe retrospectively analyzed 222 subjects undergoing polysomnography (PSG) for snoring, who received CPAP under PSG on the next day following the initial PSG. The sleep architecture of the subjects in different age groups and in groups with different severities of OSAHS was analyzed before and after adjustment for apnea-hypopnea index (AHI) or age. The sleep architecture and ventilation function of the patients with OSAHS were also analyzed after CPAP.
RESULTSN3 sleep showed the strongest correlation with AHI (r=-0.361), and REM sleep and wake after sleep onset (WASO) were the most strongly correlated with age (r=-0.211 and 0.216, respectively). The 4 age groups showed significant differences in sleep efficiency (P<0.001), N1 (P=0.015), N2 (P=0.013) and REM (P=0.030) sleeps, and WASO (P=0.001) but not in AHI (P=0.185). REM sleep decreased and WASO increased with an increasing age. The sleep efficiency and architecture were still significant different after adjustment for AHI. In 4 groups with different severity of OSAHS, N1, N2 and N3 sleeps were significant different after adjustment for age (P=0.011, 0.017, 0.001). In patients with moderate or severe OSAHS, N3 sleep increased with the increase of AHI. After CPAP for OSAHS, N1 and N2 sleeps significantly decreased, and N3 and REM sleeps increased (P<0.001).
CONCLUSIONBetween OSAHS and age, REM sleep and WTSO are more importantly affected by age, while OSAHS more strongly affects N3 sleep. CPAP can improve the sleep quality of patients with OSAHS.

Objective:To investigate the effects and potential mechanism of vitamin D supplementation on testicular function in aging rats induced by D-galactose.Methods:The aging rats were induced by D-galactose with subcutaneous injection. The animals were randomly divided into 6 groups: aging rats (DG), aging rats with low-dose vitamin D supplementation (LD), aging rats with high-dose vitamin D supplementation (HD), normal control rats(NC), normal rats with low-dose vitamin D supplementation(LN), normal rats with high-dose vitamin D supplementation (HN). The body weight, testicular weight, serum testosterone concentrations and sperm quality of the rats in each group were measured. The testis morphological changes were detected using light microscopy. The activity of superoxide dismutase (SOD) and level of malondialdehyde(MDA) were determined with spectrophotometer. The expression levels of Nrf2, GCLC, SOD2 and VDR in testis were detected by western blot.Results:At baseline, compared with NC group, testicular weight, serum testosterone level, SOD activity, Nrf2, GCLC and SOD2 expression levels were significantly decreased in DG group, while MDA level was significantly increased. After vitamin D supplementation, testicular weight, testosterone levels and SOD activity in both of HD and LD groups were significantly increased, while the MDA level was significantly decreased. The expression levels of Nrf2, GCLC, SOD2 and VDR were significantly increased.Conclusion:Vitamin D supplementation may enhance the testicular antioxidant capacity through activating Nrf2-ARE signaling pathway, and improve the testicular function in D-galactose-induced aging rats.

Objective:To investigate the application value of digital single-operator peroral cholangioscopy on the preoperative evaluation of extrahepatic cholangiocarcinoma.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 172 patients with extrahepatic cholangiocarcinoma who were admitted to the First Affiliated Hospital of Army Medical University from December 1, 2017 to April 1, 2022 were collected. There were 91 males and 81 females, aged 65(range, 45?68)years. Of 172 patients, 36 cases undergoing preoperative digital single-operator peroral cholangioscopy examination were allocated into the experimental group, and 136 cases not undergoing preoperative digital single-operator peroral cholangioscopy examination were allocated into the control group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) surgical conditions. Propensity score matching was done by the 1:1 nearest neighbor matching method and caliper setting as 0.02. Measurement data with normal distribution were expressed as Mean± SD, and t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M( Q1,Q3), and the Mann-Whitney U test was used for comparison between groups. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. The rank sum test was used for comparison of ordinal data. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of 172 patients, 60 cases were successfully matched, including 30 cases in the experiment group and 30 cases in the control group, respectively. Before propensity score matching, cases with or without preoperative bile drainage were 27, 9 in the experiment group, versus 62, 74 in the control group, showing a significant difference between the two groups ( χ2=9.86, P<0.05). The above indicators were 23, 7 in the experiment group, and 23, 7 in the control group after propensity score matching, showing no significant difference between the two groups ( χ2=0.00, P>0.05). The elimination of preoperative bile drainage confounding bias ensured comparability between the two groups. (2) Surgical conditions. After propensity score matching, there were 10 cases and 0 case without surgery in the two groups. Cases undergoing radical operation including R 0, R 1, R 2 resection were 16, 0, 4 in the experiment group, versus 18, 6, 6 in the control group, showing a significant difference between the two groups ( χ2=6.85, P<0.05). Conclusions:Preoperative digital single-operator peroral cholangioscopy exami-nation can improve the R 0 resection rate of extrahepatic cholangiocarcinoma.

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.
