Objective To investigate the incidence and pregnancy outcomes of premature rupture of membranes (PROM) in pregnant women in Beijing.Methods A retrospective multicenter study of 18 534 cases delivered in Beijing Obstetrics and Gynecology Hospital,Beijing Friendship Hospital,Daxing MCH Hospital and Tongzhou MCH Hospital from January 2011 to December 2011,was conducted.Results Among 18 534 cases,PROM occurred in 4 504 cases (24.30％),including 3 910 cases of in term PROM (21.10％) and 594 cases of preterm PROM (3.20％).The incidence of premature delivery was 6.17％ (1 144/18 534),and among 1 144 cases of premature delivery 547 cases were PROM (47.81％);the incidence of PROM was 22.75％ (3 957/17 390) in term delivery.The overall cesarean section (CS) rate was 48.50％ (8 989/18 534) and that in pregnant women with PROM was 35.55％ (1 601/4 504),but the CS rate in pregnant women without PROM was 52.66％ (7 388/14 030).The rate of postpartum hemorrhage was 13.12％ (210/1 601)in CS cases and 4.17％ (121/2 903) in vaginal delivery cases (x2 =121.361,P=0.000).The mean hospital stay for PROM was (5.3±2.9) d in CS cases and (4.3±2.3) d in vaginal delivery cases (t =-12.136,P =0.000).Conclusions Without severe maternal or fetal complications,the incidence of PROM is relatively high in Beijing region and PROM may not increase the maternal or fetal complications.Vaginal delivery is the main mode of delivery for PROM.Cesarean section may not cause less neonatal complications,but may lead to more postpartum hemorrhage and longer hospital stay.

A rapid headspace gas chromatography tandem mass spectrometric ( HS-GC/MS ) method was established for the analysis of volatile fatty acids ( VFAs ) in the feces. Feces were suspended by 6%phosphoric acid aqueous solution (1:2 m/V) and sealed in the headspace bottle for HS-GC/MS analysis. The HS-GC/MS method was optimized as follows: agitator temperature ( temp. ):80 ℃, syringe temp.:80 ℃, sample incubation time: 30 min, injection: 1 mL without split-flow. The chromatographic separation was performed on a DB-FFAP capillary column (30m×0. 25 mm×0. 25 μm) with injection port temp.:250 ℃. The temperature program ( initial temp. at 50 ℃ within first 1 min, and raised to 200 ℃ by 10 ℃/min) was employed by fixing the flow of carrier gas (high purity helium) at 1. 0 mL/min. The electron energy at -70 eV for electron impact ( EI ) ionization, ion source temp.: 250 ℃, transfer line temp.:280 ℃, the voltage of electron multiplier at 0. 95 kV. The spectra were recorded in the range of m/z 33-200 for full scan. The established HS-GC/MS method could be applied to analyze VGAs in the feces from human and rat appropriately. There are nine VFAs identified in the feces from human, and eight VFAs detected in the feces from rat by retrieving the NIST library, comparing with the standards and analyzing the MS data. Furthermore, the relative percentage contents of acetic acid, propionic acid and butyric acid accounted for roughly 85% of all VFAs by area normalization. The method is simple and sensitive, and it can be used to rapidly detect VFAs in the feces from human and rat.

To investigate the protection effect of DNA vaccine in mammalian and avian systems, the DNA vaccine was inoculated in both BALB/c mice and SPF chickens immunized with DNA vaccines encoding hemagglutinin (HA) from A/Goose/GuangDong/1/96 (H5N1) virus. The mice and chickens were immunized twice, 3 weeks apart, by electroporation into muscles or intramuscular injection. Two weeks after the second immunization, the mice and chickens were challenged with a lethal dose of homologous virus. The mice and chickens immunized by electroporation obtained completely protection against the virus, and could effectively inhibited viruses to replicating in mouse lung and chicken cloaca. At the same time, these protections were companied by high levels specific antibody to H5N1 AIV, while the blank plasmid controls experience 100 percent mortality following challenge. Furthermore, in the experiment of mice by eletroporation,stronger obviously CTL activity were observed after challenge. Thus, the cellular immune responses of the mice immunized by electroporation were exhibited. These results strongly demonstrate that HA DNA vaccines provide effective protection against influenza virus infection in mammalian and avian, and suggest that electroporation is one of the efficient gene delivery systems for the transfer of influenza DNA vaccine in both humoral immunity and cellular immunity.

The central nervous system (CNS) plays a key regulatory role in glucose homeostasis. In particular, the brain is important in initiating and coordinating protective counterregulatory responses when blood glucose levels fall. This may due to the metabolic dependency of the CNS on glucose, and protection of food supply to the brain. In healthy subjects, blood glucose is normally maintained within a relatively narrow range. Hypoglycemia in diabetic patients can increase the risk of complications, such as heart disease and diabetic peripheral neuropathy. The clinical research finds that the use of traditional Chinese medicine (TCM) has a positive effect on the treatment of hypoglycemia. Here the authors reviewed the current understanding of sensing and counterregulatory responses to hypoglycemia, and discuss combining traditional Chinese and Western medicine and the theory of iatrogenic hypoglycemia in diabetes treatment. Furthermore, the authors clarify the feasibility of treating hypoglycemia on the basis of TCM theory and CNS and have an insight on its clinical practice.

Objective:To screen the ultrasound markers of predictive value at 11-13 + 6 weeks for selective fetal growth restriction (sFGR) in monochorionic (MC) twins. Methods:A retrospective analysis of MC twin pregnancies collected prospectively from June 2020 to December 2021 at Beijing Obstetrics and Gynecology Hospital, Capital Medical University, with standardized ultrasound examinations performed at 11-13 + 6 weeks.According to the expert consensus on the diagnostic criteria for sFGR, collected MC twin pregnancies were divided into sFGR group and control group (normal MC twin group). Maternal age, maternal history, mode of conception, the incidence of increased nuchal translucency (NT) thickness, NT discordance, crown-rump length (CRL) discordance, abnormal ductus venous Doppler waveform and abnormal umbilical cord insertion position were compared between the two groups, and those markers that differed between groups were further analyzed for screening early ultrasound markers that could be used to predict sFGR. Results:A total of 106 cases were included in the analysis, 30 cases in sFGR group and 76 cases in control group. ①Compared with control group, sFGR group had a higher incidence of low fetal birth weight (below the 10th and 3rd percentile) in both surviving cases, large birth weight discordance and a higher incidence of birth weight inconsistency (difference >25%) ( P<0.001). ②Compared with control group, the CRL discordance was larger in sFGR group [7.8% (3.8%, 9.2%) versus 3.8% (1.5%, 7.2%)] and the incidence of abnormal cord insertion position (33.3% versus 6.6%) was higher, the differences were statistically significant ( P=0.004 and <0.001, respectively), whereas the differences of NT discordance, incidence of increased NT and abnormal ductus venous Doppler waveform were not statistically significant (all P values >0.05). ③CRL discordance was a risk factor for sFGR ( OR=1.136, 95% CI=1.021-1.264), with an area under the ROC curve of 0.682 (95% CI=0.576-0.787) for predicting sFGR, the sensitivity and specificity were 0.567 and 0.737 at a cut-off value of 6.5%. Abnormal umbilical cord insertion position was a risk factor for sFGR ( OR=7.100, 95% CI=2.176-23.167) with a sensitivity of 0.333 and specificity of 0.934 for predicting sFGR. Conclusions:CRL discordance and abnormal cord insertion position are risk factors for the development of sFGR and are of value in predicting sFGR in MC twins.

Objective:To explore the application and effect of autologous cartilage in rhinoplasty for patients with traumatic hernia and nasal dysfunction.Methods:From January 2017 to April 2019,30 patients with nasal trauma admitted to Department of Otorhinolaryngology Head and Neck Surgery, Daping Hospital, Army Medical University were treated for 6 days to 14 years. All patients were accompanied by different degrees of nasal deformity and nasal ventilatory disorders. They were classified into three categories: light, medium and heavy. All of them were open at the same time. Rhinoplasty and nasal septum deviation correction. For mild to moderate nasal deformity and nasal ventilatory disorders, ear cartilage was used to modify the tip of the nose and strengthen the nasal septal cartilage support to modify the deformity of the nasal back. For severe nasal deformity and nasal ventilatory disorders, we engraved the costal cartilage into a "Y" shaped monolithic stent or flank costal cartilage to form a 2+1 or 4+1 stent, and the costal cartilage stent and the septal cartilage tail end were sutured. Reshape the nasal septum frame support and the nasal column to avoid collapse of the nose.Results:Three patients had a septal hematoma after operation and recovered normally after cleansing. All patients were followed up for 2 months to 2 years, and no complications such as nasal septum perforation and nasal bridge collapse occurred. The postoperative cure rate was 60.0% (18/30). All patients had a grade I nasal drop after surgery, and the effective rate was 100% (30/30). The patient′s preoperative measurement deviation was (6.85±2.43) mm, the postoperative measurement deviation was (2.4±1.58) mm, the preoperative nasal appearance VAS score was (1.93±1.31), and the postoperative nasal appearance VAS score was (6.60±1.16), the difference in facial appearance deviation and VAS score before and after surgery was statistically significant ( P<0.05). All patients had improved nasal ventilation after operation. The preoperative nasal ventilation VAS score was (1.97±1.07), the postoperative nasal ventilation VAS score was (6.53±1.04), and the difference between preoperative and postoperative nasal ventilation VAS scores was statistically significant ( P<0.05). Conclusions:Autologous cartilage is effective in rhinoplasty in patients with traumatic nasal contraction and nasal dysfunction. One stage open rhinoplasty and nasal septum deviation surgery are performed to shorten the treatment time and improve the nasal appearance and nasal ventilation function. The patients got satisfaction.
