Objective To summarize the expreiences of management of triplet and quaternion pregnancy mothers and their in our hospital. Methods The clinical data of seven cases of multiple pregnancy (6 case of triplet and 1 case of quaternion) in our department from 1992 to 2003 were analyzed retrospectively. Results All seven patients had middle or severe anemia and hypoproteinemia in second and third trimester. The preterm sign happened in 2/3 cases in 32-36 gestation weeks. The patients were admitted in hospital in 27-34 gestation weeks because of obstetric complication. 6 triplet cases delivered during 35th-37th gestation weeks, except the quaternion one delivered at 33 gestation weeks. There were 22 newborns in those cases, the all babies Apgar's scores were above 9, the birth weights of all babies were above the 3th percent of Chinese singleton gestation and newborn estimated curves, and the birth weights of half babies were above the 10th percent position. Conclusion The key points for managing the multiple pregnancies, especially larger than 3 babies were the following ⑴All pregnant women had a good prenatal care. ⑵Pregnant women rested well, anemia must be corrected, and the adequate nutrition was supplied, especially in third trimester. ⑶Using ultrasound to determine the cervix length and evaluate the risk of preterm delivery, when the preterm delivery sign happened, the inhibiting drugs must be used cautiously and rationally. ⑷ After the antenatal dexamethasone therapy was applied around 36 gestation weeks, selective cesarean section was preferred to deliver the babies. If good prenatal care can be applied, a good outcome for triplets and quaternion can be achieved, close to that of same gestation weeks singleton.

Objective: To discuss the university students early-stage interpersonal perception and selection in internet Method; Totally 362 university students who used internet instant chat system were surveyed with the self-designed questionnaires. They were required to assess the influence degree of internet information on their feeling and choosing in a five degree scale. The differences in gender, subject and lasting time were also compared. Re-sults: (1) Age (4. 39 ± 1.94), nick name (3.71 ± 1.92) and self-explained (3.67 ± 1.97) were the most important information for choosing a friend in internet, which were higher than three most unimportant information including blood type (1.23 ±0. 80), level (1.40 ±0.95), and operation (1.41 ±0.89) (P<0.01) . (2) All students trended to evaluate others or selves information veritable. In all items, the veracity rate of self evaluate was high than 78.2% , and the veracity degrees of evaluating others'information were between 2.05 ～ 2.91. (3) Bad manners (1. 33 ±0.72), rough speech (1.41 ±0.71), and bored dialogue (1.50 ±0. 80) were the most related factors to choose friend, which were higher than three most unimportant information including no meeting chance (4.47±0.94), slow typing (3.13 ±1.12), poor motivation (2.32 ± 1.05) (P<0.01) . Conclusion: This study suggests that peoples early-stage perception and selection in internet are based on the selection, confirmation and conjecture of users, which will have certain effects on the development of network interpersonal relationship.

Purpose To investigate the clinical value of three-dimensional hysterosalpingo-contrast-sonography (3D-HyCoSy) in the assessment of fallopian tubal patency.Materials and Methods Fallopian tubal patency of 33 infertile women was assessed using transvaginal 3D-HyCoSy, and the results were compared with laparoscopically salpingoraphy, the sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of 3D-HyCoSy were evaluated.Results 3D-HyCoSy showed 20 passable fallopian tubes, 10 partially passable fallopian tubes and 36 obstructed tubes, while lapascopically salpingoraphy showed 23 passable fallopian tubes, 7 partially passable fallopian tubes and 36 obstructed tubes. The total coincidence rate of 3D-HyCoSy to assess the fallopian tubal patency was 86.4% (57/66), with the sensitivity of 93.0% (40/43), specificityof 73.9% (17/23), positive likelihood ratio of 7.15, and negative likelihood ratio of 0.20.Conclusion Tubal patency can be efficiently and accurately assessed using 3D-HyCoSy, but patients with obstructed or partially passable fallopian tubes should undergo laparoscopy to clarify.

Objective To study the characteristics of patients with low body mass index (BMI) chronic obstructive pulmonary disease(COPD). Methods A total of 38 clinically stable patients with moderate-to-severe COPD were enrolled. They were divided into two groups: underweight (UW) group (n=16,BMI<20);normal weight(NW) group(n=22, 20≤BMI<26). Body height and weight, smoking indexs, and six minutes walk distance (6MWD) were assayed. The British Medical Research Council (MRC) dyspnea scale was used to assess the degree of dyspnea. St. George's Respiratory Questionnaire (SGRQ) and Short Form 36 item Questionnaire (SF-36) were used for health-related quality of life (HRQoL) evaluation. The serum concentrations of leptin and ghrelin were detected by enzyme-linked immunosorbent assay (ELISA). Results Compared with the NW group, the inspiratory eapacity(IC), forced expiratory volume in one second (FEV), vital capacity (VC) ,most ventilate volume (MVV) and peak expiratory flow(PEF) were lower(P<0. 05) in the UW group. Residual volume-to-total lung capacity ratio (RV/TLC), smoking indexs and MRC score were higher (all P<0. 05) and 6MWD was significantly lower (P<0. 05) in the UW group than in NW group. Activity scores,impact scores and total scores of SGRQ showed significant deterioration in the UW group (P<0. 05). SF-36 also showed significantly worse scores for the parameters of the emotional and social functioning (P < 0. 05 ). Serum leptin was significantly lower ( P< 0.01 ) and ghrelin was higher in UW group than in NW group (P<0. 05). Stepwise multiple regression analyse showed that lC,mental health(MH) and physical function (PF) of SF-36, leptin,6MWD and smoking indexs were independently correlated with BMI. Conchtsions The pulmonary function, nutritional status, PF and life quality of COPD patients with low BMI were more deteriorative. The most significant influencing factor for BMI in COPD patients was IC. M H,exercise capacity,leptin level and smoking indexs were independently correlated with BMI in COPD patients. It is important to retrieve low BMI in the management of COPD patients.

Objective To explore the mechanism of spontaneous seizures in adaptor protein complex type 3B knockout mice(AP3M2KO mice).Methods AP3M2KO mice were generated.Seizures and electroencephalogram(EEG)were monitored using video camera and telemetry system.Glutamate and GABA releases were determined using in vivo microdialysis method.Results AP3M2KO mice began to suffer from spontaneous seizures 8 weeks after the birth,but did not show any other behavior abnormality.The onset of ictal discharge over the temporal region was synchronized with seizures.There were no significant differences in basal glutamate and GABA releases in hippocampus between AP3M2KO((0.35±0.08)pmol/20μl and(2.94±1.69)fmol/20μl,respectively)and wild-type mice.However,the 50 mmol/L K+-evoked GABA release was impaired in AP3M2KO mice((63.5±11.8)fmol/20μl vs(209.2±63.7)fmol/20 μl,t=4.405,P＜0.05),whereas no significant difference was found in K+-evoked glutamate release.Conclusions AP3M2KO mice suffer from epileptic seizures similar to the clinical features of human epilepsy.The impairment of inhibitory GABAergic transmission iS involved in the mechanism of spontaneous seizures in AP3M2KO mice.

Methods Eighty-two patients with vestibular paroxysmia were admitted during June 2013 and June 2017 in this study. According to the agents administered ,all patients were divided into the CBZ group(n＝ 31) ,CBZ+ Betahistine(BMT) group(n＝ 26)and OXC+ BMT group(n＝ 25).The clinical efficacy ,frequency ,vertigo and adverse reactions of three groups were compared after 3 months follow-up. Results In CBZ group ,14 cases were cured ,13 were improved ,and the effective rate was 87.1%.In CBZ+BMT group ,18 cases were cured ,7 were recovered ,and the effective rate was 96.2%.In OXC+BMT group ,15 cases were cured , 8 cases were recovered ,and the effective rate was 92.0% . There was no significantly difference in effective rate among the three groups(χ2＝0.783 ,P＝0.129).Meanwhile ,the CBZ+BMT group had the lowest frequency of vestibular paroxysmia and vertigo degree ,while the CBZ group was the highest ;the difference in the frequency and vertigo degree between groups was statistically significant (P＜ 0.05).Furthermore ,the incidences of side-effects were 51.6%(n＝ 16) ,30.8%(n ＝ 8)and 16.0%(n＝4)in the CBZ group ,CBZ+BMT group and OXC+BMT group ,respectively. Conclusions The effect of Carbamazepine and Oxcarbazepine for vestibular paroxysmia is similar ,and is safely and significantly improved when combined with Betahistine.

Objective:To explore the application of the mandarin Chinese version of the Leicester cough questionnaire (LCQ-MC) in the chronic disease management of adult patients with severe asthma.Methods:Thirty patients with severe asthma without a smoking history who received treatment and chronic disease management in the First Affiliated Hospital of Guangxi Medical University from December 2018 to December 2020 and met the inclusion criteria were selected as the research subjects. Their clinical symptoms, LCQ-MC, asthma control test (ACT), mini asthma quality of life questionnaire (MiniAQLQ), visual analogue scale (VAS) and lung function test were recorded. The reliability of LCQ-MC and its correlation with ACT, MiniAQLQ, VAS and lung function were analyzed.Results:Among the 30 patients, there were 14 males and 16 females, with an average age of (50.5±10.5) years old and a medical history of (38.3±15.5) years. The main manifestations were cough which was observed in 29 cases (96.7%), wheezing in 25 cases (83.3%), nasal symptoms in 14 cases (46.7%) and chest tightness in 11 cases (36.7%). All lung functions were consistent with the diagnosis of asthma. The total score of LCQ-MC was (16.1±4.2), in which the physiological, psychological and social dimensions were (5.0±1.2), (5.6±1.6), (5.5±1.7), respectively; and ACT (18.9+5.5), MiniAQLQ (4.9±1.4), VAS (33.5±32.4). The Cronbach′s α for the questionnaire was more than 0.70, and the results were positively correlated with ACT and MiniAQLQ ( r=0.553, 0.593, P=0.002, 0.001), negatively correlated with VAS ( r=-0.762, P<0.001). The correlations between LCQ-MC and these scores were consistent with the results after 6 months. Conclusion:Cough is an important symptom of severe asthma, and LCQ-MC can be effectively used for evaluation and chronic disease management of adult patients with severe asthma.

OBJECTIVE To investigate the prognostic value of pre-treatment serum lactate dehydrogenase(LDH)levels in patients with locally recurrent nasopharyngeal carcinoma(NPC)treated with salvage intensity-modulated radiotherapy(IMRT)and to determine its association with rT staging.METHODS The records of 97 patients with locally relapsed and non-metastatic NPC who received salvage IMRT treatment in our center from January 2018 to April 2022 were collected,including 51 patients who died,18 patients with distant metastases,30 patients with local failure,and 67 patients with prognostic adverse events(death,distant tumors/local metastases).Clinical data,local failure-free survival(LFFS),distant metastasis-free survival(DMFS)and overall survival(OS)were obtained from all patients,and the relationship between LDH and the prognosis of salvage IMRT therapy in NPC patients was analyzed.RESULTS The serum LDH level before salvage IMRT was significantly higher in the death[221.25(178.24,339.13)U/L vs.124.82(79.0,159.50)U/L,Z=-5.122],local failure[230.75(170.89,394.50)U/L vs.157.85(91.78,216.95)U/L,Z=-3.442],distant metastasis[261.62(153.55,465.50)U/L vs.168.98(101.75,237.75)U/L,Z=-2.478]and poor prognosis group[220.05(167.20,506.16)U/L vs.93.45(69.95,154.35)U/L,Z=-6.018],and all P<0.05.Serum LDH levels were divided into dichotomous variables according to median values(≥177.50 U/L vs.<177.50 U/L),the Cox univariate model found that the hazard ratios of LDH affecting LFFS,DMFS,OS and toxic-related death(TRD)were 3.759(1.660-8.558),4.217(1.383-12.861),3.226(1.715-6.069),3.363(1.750-6.463),P<0.05.LDH remained an independent prognostic factor for LFFS,DMFS,OS,and TRD in multivariate regression analysis(P<0.05).Compared with patients with LDH<177.50 U/L,more patients in the LDH≥177.50 U/L group had local progression-related death,and the no LFFS stage,no DMFS stage and OS were shorter in the LDH≥177.50 U/L group(log rank=11.624,7.559,14.758),P<0.05.In predicting overall survival,adding LDH to the rT stage is preferable to the rT stage alone.CONCLUSION LDH is an important factor in predicting LFFS,DMFS,OS,and TRD after saving IMRT in patients with locally relapsed,non-metastatic NPC,and the value of LDH combined with rT staging in predicting overall survival is high.

Objective To investigate the prevalence rate of non-obese fatty liver disease and its influencing factors, and to provide a reference for the prevention and treatment of fatty liver disease. Methods A total of 23 545 individuals who underwent physical examination in Karamay Central Hospital from January to December 2015 and had complete data of abdominal ultrasound, body mass index (BMI), age, and sex were screened out to analyze the prevalence rate of fatty liver disease, and 7484 individuals with normal BMI who had complete data of triglyceride (TG), fasting blood glucose, and alanine aminotransferase (ALT) were further screened out to perform a multivariate analysis. The t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between groups. A multivariate logistic regression analysis was performed to investigate independent influencing factors for non-obese fatty liver disease. Results In 2015, the prevalence rate of fatty liver disease was 30.2% (7116/23 545) among the individuals who underwent physical examination in Karamay Central Hospital. A stratified analysis based on BMI showed that the individuals with emaciation, normal BMI, overweight, and obesity had a prevalence rate of 0.8% (6/706), 9.3% (919/9899), 38.4% (3404/8870), and 68.5% (2787/4070), respectively (all P < 0.05), and male individuals had a significantly higher prevalence rate of fatty liver disease than female individuals (all P < 0.05). Among the 919 patients with non-obese fatty liver disease, young, middle-aged, and elderly patients accounted for 40.7% (374/919), 46.1% (424/919), and 13.2% (121/919), respectively. For the individuals with normal BMI, there was no significant difference in the prevalence rate of fatty liver disease between middle-aged and elderly individuals (14.5% vs 16.8%, P > 0.05), while both of them had a significantly higher prevalence rate than the young individuals (14.5%/16.8% vs 6.0%, P < 0.05). Young and middle-aged male individuals had a significantly higher prevalence rate of fatty liver disease than their female counterparts ( χ 2 =99.40 and 43.29, both P < 0.001), while the elderly male individuals had a significantly lower prevalence rate than their female counterparts ( χ 2 =9.81, P =0.002). For the individuals with normal BMI, the individuals with normal TG had a prevalence rate of fatty liver disease of 5.0% (311/6273), while those with elevated TG had a prevalence rate of 26.8% (325/1211), with a significant difference between the two groups ( χ 2 =624.90, P < 0.001). The multivariate logistic regression analysis showed that age, BMI, ALT, fasting blood glucose, TG, and serum uric acid level were independent influencing factors for fatty liver disease in individuals with normal BMI (all P < 0.001). Conclusion There is a relatively high prevalence rate of non-obese fatty liver disease among individuals undergoing physical examination in Karamay Central Hospital, and 61.5% of the patients with non-obese fatty liver disease have glucose or lipid metabolic disorders. Serum TG level may be used as a simple and effective screening index for non-obese fatty liver disease.
