Objective@#To investigate the prevalence and types of maternal near miss in Hangzhou City from 2015 to 2020, so as to provide insights into early identification and interventions for maternal near miss.@*Methods@#The data of maternal near miss in 5 hospitals of Hangzhou City from 2015 to 2020 were collected from China's National Maternal Near Miss Obstetrics Surveillance System, and the incidence and mortality of maternal near miss, types of pregnancy-related complications/comorbidities and types of critical illness were descriptively analyzed.@*Results@#Totally 230 490 pregnant and lying-in women were recruited in 5 hospitals in Hangzhou City from 2015 to 2020, and there were 182 514 live births, 177 428 women with pregnancy-related complications/comorbidities, and 1 790 cases of maternal near miss with a 0.98% annual incidence rate. The incidence of maternal near miss was high in 2019 (1.18%). The hospital mortality and death index were respectively 3.29/105 and 0.33% among pregnant and lying-in women from 2015 to 2020, and there was no death found among pregnant and lying-in women from 2018 to 2020. The main pregnancy-related complications/comorbidities included anemia (79.33%), obstetric hemorrhagic disorders (69.83%), and gestational hypertension (16.65%). The main critical illness among maternal near miss included coagulation dysfunction (87.23/104), cardiovascular dysfunction (20.44/104), and respiratory dysfunction (9.70/104).@*Conclusions@#The incidence of maternal near miss was high and the hospital mortality appeared a reduction tendency among pregnant and lying-in women in Hangzhou City from 2015 to 2020. Coagulation dysfunction is the primary critical illness among maternal near miss, and the management of anemia and hemorrhagic diseases requires to be improved.

Objective To explore the role of visual oculomotor-vestibular eye balance function in the diagnosis of central and peripheral vertigo. Methods From January 2015 to June 2016,one hundred and sixty-two patients with central vertigo who were treated at Kailuan General Hospital were enrolled in the study, including 124 males and 38 females, aged ( 64. 09 ± 10. 98 ) years old; there were 166 cases of peripheral vertigo,75 males and 91 females,aged (52. 13±12. 20) years old. Spontaneous nystagmus test,gaze test,position test, saccade test, smooth visual tracking test, visual single-speed test, visual sinus test, swivel chair rotation- emergency stop test using infrared video nystagmus and static balance posture instrument,open-closed eye hard plate erect test, open-closed eye sponge soft bottom erect test balance function electrophysiological test were conducted. Results The detection rate of pathological spontaneous nystagmus and pathological gaze nystagmus was higher in the central vertigo group than that in the peripheral vertigo group (χ2=5. 674,16. 458,P<0. 05) . The occurrence rate of positional nystagmus was higher in peripheral vertigo group than that in central vertigo group (χ2=48. 896,P<0. 001). The abnormal rate of scanning test,stable visual tracking test,visual movement single speed and sinusoidal test,and static balance posture test were higher in the central vertigo group than those in the peripheral vertigo group (χ2 =137. 169, 166. 972, 150. 877, 150. 877, 27. 273, P<0. 001 ) , while the abnormal rate of rotating chair sudden stop test was higher in the central vertigo group than that in the peripheral vertigo group (χ2=51. 000,P<0. 001) . The abnormal results were mainly scanned underflush and slow scan in central vertigo group (χ2=103. 846,4. 296,P<0. 05),stable visual tracking curve (χ2=147. 389,4. 296,P<0. 05) in type III-IV,and the gain of nystagmus decreased unilaterally and bilaterally (χ2=47. 531,44. 477, 52. 529,53. 255,P<0. 001) . Anomalies of proprioception in reverse and vertical nystagmus and static balance posture were induced by rotating chair sudden stop test (χ2=11. 847, 23. 778, P<0. 001 ) , while peripheral vertigo group showed unilateral decrease of nystagmus gain induced by rotating chair sudden stop test. (χ2=79. 771, P < 0. 001 ) . Conclusion The patients with peripheral vertigo have obvious body position spontaneous vestibular response and vestibular oculomotor system dysfunction, while the patients with central vertigo mainly have visual and oculomotor system dysfunction,and may be accompanied by vestibular oculomotor system and vestibular spinal reflex dysfunction.

OBJECTIVE:To evaluate the effects of 3 kinds of serum containing blood-activating and stasis-eliminating TCM compound formulas on aggressive behavior,Janus kinase (JAK)/signal transduction and transcriptional activator (STAT) pathway of glioma U251 cells. METHODS:Rats were randomly divided into normal saline group (5 mL/kg),Taohong Siwu decoction group(5.7 g/kg),Xuefu Zhuyu decoction(8.5 g/kg)and Didang decoction(2.8 g/kg),calculated by crude drug,intragastrically administrated once a day,for 10 d. 10% drug-containing serum culture medium was prepared after 2 h of last administration. After 10% drug-containing serum culture medium intervening U251 cells for 1 week,Transwell method was conducted to detect the cell invasion rate, Western blot was adopted to detect the metal matrix protease 2 (MMP-2), MMP-9, phosphorylated JAK2 (p-JAK2),phosphorylated STAT3(p-STAT3)protein expression;and real-time fluorescence quantitative polymerase chain reaction method was used to detect MMP-2,MMP-9 mRNA expression. RESULTS:Compared with blank serum,Xuefu Zhuyu decoction drug-containing serum can reduce cell invasion rate (P0.05). CON-CLUSIONS:In the 3 kinds of blood-activating and stasis-eliminating TCM compound formulas,Xuefu Zhuyu decoction shows sig-nificant invasive effect on inhibiting U251 cells;the mechanism may be related to inhibiting the activation of JAK2/STAT3 signal pathway and decreasing MMP-2,MMP-9 gene and protein expressions.

BACKGROUND: Construction of recombinant adenovirus plasmid plays a central role in preparation of recombinant adenovirus.However, conventionally intracellular homologous recombination method is limited by complex procedures, low successful ratio,and long experimental cycle.OBJECTIVE: To construct the recombinant replication-defective adenovirus vector containing interleukin-10 (Ad.dL-10) in a SD rat, and to provide experimental evidences for eukaryotic expression and animat model studying.DESIGN, TIME AND SEI-FING: Opening study was conducted in the First Affiliated Hospital of Sun Yat-sen University from July 2005 to April 2006.MATERIALS: A SD rat, AdEasy system (USA), ThermoscdptTMRT kit & Tdzol (USA), and HEK-293 (Guangzhou, China) were used in this study. The primer of rlL-10 gene of clone rat was synthesized and sequenced in Shanghai, China.METHODS: rlL-10 gene was cloned from total RNA of healthy SD rat spleen tissue with RT-PCR, and then recombinant adenovirus plasmid named pAd.rlL-10 was obtained by homologous recombination within E.ColiBJ5183 carded with AdEasy-1 system. Last, the recombinant adenovirus was packaged, proliferated by HEK-293 cells and purified.MAIN OUTCOME MEASURES: The Ad.rlL-10 was identified using Western blot and RT-PCR methods.RESULTS: rlL-10 gene was successfully cloned from fresh spleen tissue of a SD rat and incorporated into recombinant adenovirus plasmid pad in order to obtain the Ad.rlL-10. Western blot and RT-PCR showed the rlL-10 gene and protein expressions in the cells. Finally, the rlL-10 recombinant adenovirus was obtained with the titers of 1.0x1014 pfu/mL after amplification and purification.CONCLUSION: AdEasy-1 system characterizing by simple operation and reliable results is commonly used to obtain enough quantity and quality adenovirus after homologous recombination, and HEK-293-induced package, amplification, and purification.
