Gestational diabetes refers to the first occurrence or discovery of different degrees of abnormal glucose tolerance during pregnancy, which is one of the most common complications during pregnancy. As the incidence rate increased year by year, the complications of mother and child increased significantly. In recent years, gestational diabetes mellitus has been paid more and more attention. Most of the current researches are about the diagnosis and treatment of gestational diabetes 24 weeks and later, and the theoretical basis for the screening method and treatment of early gestational diabetes is still lacking. With the further understanding of early gestational diabetes mellitus and its adverse maternal and infant pregnancy outcomes, it is imperative to actively carry out the research on the screening and treatment of early gestational diabetes mellitus.

Objective To investigate the effects of suramin application in acute angle closure glaucoma surgery patients.Methods A prospective study method was used.From February 2012 to January 2016,178 acute angle closure glaucoma surgeries in our hospital for treatment were selected,and were equally divided into observation and control groups (89 cases in each group) according to the order of admission,and two groups were given filtration surgery.The observation group was treated with suramin adjuvant therapy after surgery.The duration were 1 ～ 14 d after operation.The prognosis of two groups was observed.Results All patients were successfully completed surgery.The intraoperative and postoperative complications were no seriously occurred;the postoperative intraocular pressure in the observation group and the control group were (11.52 ± 3.24) mmHg and (16.98 ± 5.33) mmHg that compared preoperative [(31.98 ± 5.22) mmHg,(31.87 ± 5.11) mmHg] with significantly different (P ＜ 0.05),while the observation group was significantly lower than that of the control group (P ＜ 0.05).The postoperative peak systolic velocity (PSV) and end diastolic velocity (EDV) values of the central retinal artery of the observation group and the control group were significantly higher than that of preoperation (P ＜ 0.05),and the postoperative PSV and EDV values of the central retinal artery of the observation group were significantly higher than that in the control group (P ＜ 0.05).The postoperative ratios of functional filtering bleb in the observation group and control group were 80.9％ and 60.7％,respectively.The observation group was significantly higher than that of the control group (P ＜ 0.05).Conclusions The application of suramin in acute close angle glaucoma filtration surgery can promote the function of filtering bleb and intraocular pressure reduction,and improve the ocular blood flow speed that has good application effects.

Objective To observe the effect of Danzhi Jiangtang Capsules(DJC) on serum interleukin-18 (IL-18),cystatin C (CysC) and relative biochemical indexes in patients with early diabetic kidney disease(DKD),and to explore its protective action on the kidney.Methods Sixty-two hospitalized patients with early diabetic nephropathy (period 11-Ⅲ) in Endocrinology Department of the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine were divided into western medicine group and DJC group,31 cases in each group.The patients in western medicine group received conventional hypoglycemic drugs,and DJC group received DJC based on the treatment for the western medicine group.Before and after treatment,we observed the levels of serum IL-18,CysC,fasting plasma glucose (FPG),2-hour postprandial glucose (2hPG),glycosylated hemoglobin (HbA1c),serum creatinine (SCr),blood urea nitrogen (BUN),microalbumin (mAlb),urinary albumin /creatinine ratio (UACR),and estimated glomerular filtration rate (eGFR).Results The total effective rate was 90.0％ in DJC group and 76.7％ in the western medicine group,there being significant difference between the two groups(P ＜ 0.05).After treatment,the main traditional Chinese medical syndrome scores of DJC group were significantly lower than those before treatment,and the improvement was better than that of the western medicine group (P ＜ 0.05 or P ＜ 0.01).After treatment,the serum levels of IL-18,CysC,2hPG,SCr,BUN,mAlb,UACR in the two groups were significantly lower than those before treatment (P ＜ 0.05 or P ＜ 0.01),while eGFR level was higher than that before treatment (P ＜ 0.05 or P ＜ 0.01),and the improvement effect (except for BUN) in the DJC group was superior to that in the western medicine group(P ＜ 0.01).DJC had an effect on lowering the FPG and HbA1c (P ＜ 0.05 or P ＜ 0.01 compared with those before treatment),and the western medicine had no obvious effect on the two indexes (P ＞ 0.05).The results of Spearman correlation analysis showed that IL-18 was correlated with CysC,IL-18 and CysC were correlated with HbA1c,mALB and uACR.Conclusion DJC can protect renal function of patients with early diabetic nephropathy.

ObjectiveTo investigate the effects of ziprasidone on the behavior and the expression of pERK1/2 in posttraumatic stress disorder(PTSD) model rats.Methods 24 adult male SD rats weighing (200 ±20) g were randomly divided into four groups (n =6):control group,single prolonged stress and foot shock (SPS&S) group,ziprasidone group and ziprasidone + U0126 group.The fear response to environment,high alertness,and anxiety & depression behavior of rats were tested by the open field,elevated plus-maze,and the expression of pERK1/2 was measured by Western blot.ResultsIn open field test(OFT),the SPS&S group( (76.23 ± 54.76) cm for horizontal motion distance,(4.60 ± 1.14) for the number of entering central region) showed significant difference compared with control group ( (343.77 ± 74.22 ) cm,( 12.40 ± 3.36 ) ) or ziprasidone group ( ( 274.98± 83.56) cm,( 12.00 ± 2.92) ) (P ＜ 0.01 ),but showed no significant difference with ziprasidone + U0126 group ( ( 138.14 ± 41.98) cm,(5.00 ± 1.58) ) (P ＞ 0.05 ).The results of elevated plus maze (EPM) were in accordance with the results of OFT.The expression of pERK1/2 in SPS&S group and ziprasidone + U0126 group showed significant decrease when compared with control group or ziprasidone group (P ＜ 0.01 ).ConclusionZiprasidone can obviously improve fear response to environment,high alterness and anxiety & depression behavior of rats,and these effects of ziprasidone may be carried out by up-regulation the expression of pERK1/2.

Objective To investigate the clinical features, diagnosis and treatments of pelvic abscess with endometriosis. Methods A retrospective analysis was performed on 129 cases of pelvic abscess in Peking Union Medical College Hospital from January 2000 to January 2016. Among them, 34 women with endometriosis were divided into the study group and the others were in the control group. The clinical characteristics, therapeutic regimens and outcomes were compared. Results (1) General conditions:there were no statistic differences between the two groups in age, WBC, serum CA125, intrauterine device in use, pelvic inflammatory disease history;while incidence rates of dysmenorrhea (65%, 22/34) and infertility (21%, 7/34) in the study group were higher than those in the control group (all P<0.05). (2) Clinical manifestations:fever, abdominal pain and pelvic mass were the main symptoms in two groups. The incidence rates of septic shock were 12%(4/34) in the study group and 2%(2/95) in the control group (P<0.05). (3) Treatment:treatment with puncture all failed in the study group (7/7) and surgeries were required. In contrast, there was only 1/19 treatment failure with puncture in the control group. The puncture failure rates were statistically significant (P<0.05). Compared with the study group and the control group, there were significant differences (P<0.05) in the operation time of laparoscopic surgery [(76±41) versus (53±21) minutes] and of laparotomy [(168±58) versus (116±35) minutes], intra-operative blood loss of laparoscopic surgery [(216±296) versus (43±36) ml] and of laparotomy [(448 ± 431) versus (145 ± 24) ml]. Conclusions Pelvic abscess in women with endometriosis is more severe and refractory to antibiotics and puncture treatment. Active surgical intervention is required. Although surgical procedures are often difficult, prognosis is comparatively satisfied.

This investigation was aimed to detect the carotid elasticity in normal adults by use of echo-tracking (ET) technique. The stiffness parameter (beta), pressure-strain elasticity modulus (Ep), arterial compliance (AC), argumentation index (AI) and one-point pulse wave velocity (PWV beta) of carotid in 145 normal adults with the average age of 47.0 were calculated. The population were divided into five groups according to age: 20-29 y, 30-39 y,40-49 y, 50-59 y and > or = 60 y. The elasticity parameters between left and right side, between male female and between different age groups were compared using SAS 6.12 statistic software. There was no difference in carotid elasticity regarding the side and gender. The carotid beta, Ep, AI and PWV beta were noted to increase with age while AC was noted to decrease with age. The carotid elasticity was found to correlate with age significantly, but not with side and gender. This change can be detected by ET technique.

Objective: To explore the association of tobacco/alcohol-excessive Internet usage and insufficient sleep with depressive symptoms among middle school students, so as to provide a reference for improving mental health of middle school students. Methods: In accordance with the cluster random sampling method, a total of 18 484 middle school students in Shanghai were surveyed from September to November 2022. Tobacco/alcohol-excessive Internet usage and sleep duration with depressive symptoms were assessed using the relevant scale items included in the questionnaire of Surveillance for Common Disease and Health Risk Factors among Students. The χ 2 test was used for inter group comparison, Logistic regression analysis and likelihood ratio test were used to analyze the independent and aggregated associations of tobacco/alcohol-excessive Internet use and insufficient sleep wiht depressive symptoms. Results: Self reported rates of tobacco/alcohol-excessive Internet usage, insufficient sleep and depressive symptoms among adolescents were 14.7%, 73.5% and 16.3%, respectively. Tobacco/alcohol-excessive Internet usage ( OR=2.69, 95%CI =2.44-2.97) and insufficient sleep ( OR=1.76, 95%CI =1.58-1.95) were associated with depressive symptoms ( P <0.05). Compared to middle school students with no tobacco/alcohol-excessive Internet usage and sufficient sleep, those with both tobacco/alcohol-excessive Internet usage and insufficient sleep showed the higher rate of depressive symptoms ( OR=4.71, 95%CI =4.08-5.44, P <0.05). Further stratified analysis results showed that, compared to the boys and the high school students, the separate and joint association of tobacco/alcohol-excessive Internet usage and insufficient sleep with depressive symptoms were more pronounced in the girls and the middle school students [ OR (95% CI ) for tobacco/alcohol-excessive Internet usage were 3.09 (2.68-3.56) and 4.74 (3.86-5.83), respectively; OR (95% CI ) for insufficient sleep were 1.86 (1.60-2.17) and 2.00 (1.58-2.53), respectively; and the OR (95% CI ) for the joint association were 6.05 (5.01-7.31) and 9.15 (6.98-11.99), respectively, P <0.05]. Conclusions Tobacco/alcohol-excessive Internet usage and insufficient sleep are associated with depressive symptoms in middle school students. Prevention and control strategies for adolescent mental health should be developed with consideration of health related behaviors, and also need to be tailored by focusing on gender and grade differences.

Web-based medical education has permeated into almost every corner of traditional med-ical teaching, persistently upgrading the medical teaching models and qualities, and network teaching has become the hot spot of modern education mode.Although the medical network education industry is in good shape, due to many factors, the development of pediatric imaging network education goes slowly. By com-paring current situation of our and other countries' pediatric imaging websites, this study aims to reveal the deficiencies of domestic online teaching in pediatric imaging, and further, to probe the practical meaning and strategy in construction of pediatric imaging teaching website stations, so constructing our own website stations is beneficial for the development of pediatric imaging education of our country.

Objective:Cerebral ischemia reperfusion injury(CIRI)can cause damage to distant organs,such as the gastrointestinal tract,through the gut-brain axis.Melatonin is known to play a neuroprotective role by activating specific receptor pathways.However,the changes of melatonin receptors in the gastrointestinal tract after brain injury and their relationship with intestinal injury are still unclear.Methods:Twenty-four male Sprague-Dawley rats were randomly di-vided into the Sham group and CIRI group.The CIRI model was prepared by Zea-Longa method.The jejunum,ileum,and colon tissues of the rats were collected 2 h after ischemia and 24 h after reperfusion.The damage of intestinal and brain tissues was observed by using 2,3,5-triphenyl tetrazolium chloride(TTC)and HE staining.The positive expres-sion of zonula occludens-1(ZO-1)and Claudin5 was observed by immunofluorescence staining.The melatonin receptor 1(MT1)and melatonin receptor 2(MT2)expression was detected by reverse transcription-quantitative polymerase chain reaction(RT-qPCR),immunofluorescence staining and Western Blot.The correlation between the melatonin receptors and intestinal tight junction proteins was analyzed by general linear regression.Results:TTC staining showed that the infarct size of rats in the CIRI group was significantly higher than that in the Sham group.HE staining showed that intestinal villi was broken and shortened,and goblet cells were reduced in the CIRI group.The results of immuno-fluorescence staining revealed that the positive expression of ZO-1 and Claudin5 in the intestinal tissues of rats in the CIRI group was significantly lower than that in the Sham group(P＜0.05).Compared with the Sham group,the RT-qPCR revealed a significantly lower expression of MT1 and MT2 mRNA in the CIRI group(P＜0.05),and the decrease in colon tissue was the most obvious.The results of immunofluorescence staining and WB also showed that the expression of MTl and MT2 in the CIRI group was significantly lower than that in the Sham group(P＜0.05).A gen-eral linear regression analysis revealed the difference in mean fluorescence intensities of MT1+and MT2+between the Sham group and the CIRI group were positively correlated with the difference of ZO-1+and Claudin5+between the two groups.Conclusion:After CIRI,the expression of both MT1 and MT2 receptors in various intestinal segments was de-creased,and the decrease in colon tissue was the most significant.It is suggested that the poor recovery of stroke may be related to the decrease of melatonin receptor.
