Objective · To investigate the intention of quitting smoking and influencing factors among husbands in gestational households in Shanghai and provide a scientific basis for establishing smoking cessation strategies. Methods · Pregnant women and their spouses who received antenatal examination in 5 hospitals in Shanghai were asked to finish two versions of questionnaires respectively. Basic demographic information, smoking history, history of smoking cessation and intention of quitting smoking were investigated. The database was set up by EpiData 3.1, and data were analyzed by SPSS 22.0, such as descriptive analysis, χ2 test (univariate), and Logistic regression analysis (multivariate). Results · A total of 282 questionnaires were sent to smoking husbands and 266 effective questionnaires got back with the effective rate of 94.3%. Among them 34.2% smoking husbands had intention of quitting smoking, 18.4% were trying to quit, and 22.9% had tried to quit before. Single-factor analysis showed that influencing factors for intention of quitting smoking among smoking husbands in gestational households included the daily cigarette consumption, overall opinion for smoking, the knowledge about the harm of passive smoking to pregnant women and fetuses, having smoking cessation experience or not, how many people smoking among five intimate friends except family members (P<0.05). Multivariate Logistic regression analysis showed that intention of quitting smoking had relationship with the daily cigarette consumption (OR = 0.456, 95% CI: 0.245 ~ 0.852), overall opinion for smoking(OR=2.443, 95% CI: 1.008 ~ 5.921), having smoking cessation experience or not (OR =0.316, 95% CI: 0.162 ~ 0.616). Conclusion · Intention of quitting smoking is relatively strong in gestational households. It is recommended to strengthen the education of tobacco control for smoking husband in gestational households, and encourage smokers who had smoking cessation experience before to quit smoking again.

OBJECTIVETo observe the immediate antihypertensive effect of guasha combined with bleeding therapy for mild (grade I) hypertension.

METHODSThirty patients with mild (grade I) hypertension and 30 cases with normal blood pressure were compared. Areas and acupoints in governor vessel, meridian of foot-taiyang, meridian of hand-yangming and meridian of foot-yangming were scraped for 3 times, which was followed by bleeding therapy. The blood pressures after each guasha and bleeding therapy were recorded as well as the skin temperature in Dazhui (GV 14) after each guasha. The treatment was given once a week and totally 4 treatments were given.

RESULTSThere were significant antihypertensive effects after the first guasha, the second guasha and the third guasha and bleeding therapy (all P<0.01), in which guasha combined with bleeding therapy had the most significant antihypertensive effect (P<0.01). The skin temperature in Dazhui (GV 14) was obviously increased after three times of guasha (all P<0.01).

CONCLUSIONGuasha or combined with bleeding therapy has better antihypertensive effect for mild hypertension, which is likely to be related with warming stimulation on meridians and acupoints.

AIM: To explore the characteristic of relaxation of porcine cornea after LASIKMETHODS: Usual LASIK was performed on fresh porcine corneas with stable intraoculer pressure (IOP) maintained through optic nerve irrigation. The ablation depth on stroma is 30%, 50% and 70% respectively. Then the dumbbell-shaped corneal strip specimens were cut and stored in 20% Human Albumin solution for use (4℃).Sip up the Albumin solution on specimens, and fixed them on homemade jig. Stress relaxation tests were erformed on Tytron250 Dynamics Experiment System. the loading speed was 385mm/min,extending ratewas 1.5, and relaxation time was 1 000s. The data werecollected electronically and automatically.RESULTS: In LASIK procedure, though a single flap-cutting can cause a little reduction of corneal stress relaxation (P＜0.05,P=0.49), the cornea may still remain its property of visco-elasticity. When ablation depth was 30% or more, corneal stress relaxation decreased to almost one half (P＜0.01).The change of corneal stress relaxation degree in vertical meridian specimen was lower than that in horizontal specimen, especially when ablation depth was 70%, and it's statistically significant (P＜0.001). In LASIK operation, the more depth the ablation, the more reduce the stress relaxation degree, and it's easy to cause deformation and creep deformation.CONCLUSION: The changes of the stress relaxation in verticai and longitudinal meridian specimens are similar, and slightly obvious in longitudinal specimen, especially in 70%ablation group.

Objective To investigate the learning curve of Da Vinci robot-assisted laparoscopic radical gastrectomy for gastric cancer.Methods The retrospective cohort study was conducted.The clinicopathological data of 42 patients who underwent Da Vinci robot-assisted radical gastrectomy for gastric cancer in the First Affiliated Hospital of Xi'an Jiaotong University from October 2017 to August 2018 were collected.There were 30 males and 12 females,aged from 36 to 84 years,with an average age of 59 years.The learning curve was evaluated using the cumulative sum (CUSUM) analysis and the best fitting curve method.According to the minimum number of surgeries required to cross the learning curve,the patients were divided into learning stage group and mastery stage group.Then general data and surgical efficacy of the two groups were compared.Observation indicators:(1) surgical situations;(2) results of CUSUM analysis;(3) comparison of general data between the two groups;(4) comparison of surgical efficacy between the two groups;(5) follow-up.Patients were followed up by outpatient examination or telephone interview to detect the postoperative complications,tumor recurrence and metastasis up to February 2019.Measurement data with normal distribution were presented as Mean±SD,and comparison between groups was done using the independent sample t test.Count data were represented as absolute number,and comparison between groups was analyzed using the chi-square test or Fisher exact propability.Comparison of ordinal data between groups was analyzed using the Mann-Whitney U test.Results (1) Surgical situations:all the 42 patients underwent Da Vinci robot-assisted radical gastrectomy for gastric cancer successfully,without conversion to open surgery or perioperative death.Fourteen out of 42 patients underwent Da Vinci robot-assisted total radical gastrectomy and 28 underwent Da Vinci robot-assisted distal radical gastrectomy.The operation time and docking time were (213±31)minutes and (26± 11)minutes.The operation time and docking time had a tendency to decreasing as the surgical cases increasing.(2) Results of CUSUM analysis.The CUSUM learning curve were best modeled as a polynomial with equation:CUSUM (operation time)=0.016 9X3-1.913 3X2+ 50.985X-16.595,CUSUM (docking time) =0.012 8X3-1.070 7X2 + 22.189X-23.097 respectively (X means the surgical case).The P value of fitting test of models was ＜ 0.05,with goodness-of-fit (R2) as 0.960 and 0.985.The CUSUM learning curve of operation time reached its peak when the number of surgical cases accumulated to the 19th case.Nineteen cases were the minimum number of surgeries required to cross the learning curve.Similarly,The CUSUM learning curve of docking time reached its peak when the number of surgical cases accumulated to the 14th case,and 14 cases were the minimum number of surgeries required to skillfully master robot installation across the learning curve.(3) Comparison of general data between the two groups:patients were divided into learning stage group and mastery stage group with 19 cases as the cut-off point.Males,females,age,body mass index (BMI),cases in grade 1,2,3 of American society of anesthesiologists (ASA),cases with previous abdominal surgery history,cases with basic diseases,cases in T1,T2,T3,T4 stages of preoperative ultrasonic gastroscopic tumor T staging,maximum tumor diameter,cases in Ⅰ,Ⅱ,Ⅲ stages of postoperative clinical staging,cases with total gastrectomy and distal gastrectomy (surgical method) were 14,5,(60± 13)years,(23.7±2.9)kg/m2,1,16,2,3,8,5,3,3,8,(4.1±3.5)cm,6,7,6,10,9 in the learning stage group,and 16,7,(58±10)years,(23.7±1.3)kg/m2,1,17,5,2,14,3,6,9,5,(4.7±2.7)cm,8,9,6,18,5 in the mastery stage group,respectively.There was no significant difference in the sex,age,BMI,ASA score,basic diseases,preoperative ultrasonic gastroscopic tumor T staging,maximum tumor diameter,postoperative clinical staging,and surgical method between the two groups (x2 =0.086,t =0.475,-0.007,Z =-0.884,x2 =1.469,Z =-0.301,t =-0.651,Z =-0.079,-0.236,x2 =3.076,P ＞ 0.05).There was no significant difference in the previous abdominal surgery history between the two groups (P ＞ 0.05).(4) Comparison of surgical efficacy between the two groups:operation time,volume of intraoperative blood loss,number of lymph nodes harvested,time to first liquid food intake,cases with postoperative complications and duration of postoperative hospital stay were (230±25) minutes,(176± 103) mL,21±7,(5.1 ± 2.0) days,2,(9.3± 2.5)days in the learning stage group,and (191±18) minutes,(95±41)mL,21±6,(4.7±1.7)days,3,(8.4± 2.1)days in the mastery stage group,respectively.There were statistically significant differences in the operation time and volume of intraoperative blood loss between the two groups (t =5.951,-3.359,P＜0.05).There was no statistically significant difference in number of lymph nodes harvested,time to first liquid food intake,and duration of postoperative hospital stay between the two groups (t =-0.120,0.538,1.303,P＞0.05).There was no significant difference in the cases with postoperative complications between the two groups (P＞0.05).(5) Follow-up:all the 42 patients were followed up for 6-16 months,with a median time of 11 months.No serious long-term complications,tumor recurrence and metastasis or death occurred during the follow-up.Conclusions The CUSUM learning curve of Da Vinci robot-assisted radical gastrectomy for gastric cancer can be divided into the learning stage and the mastery stage.It is suggested that the surgeons need to finish 19 cases or more to master Da Vinci robot-assisted radical gastrectomy for gastric cancer.

Objective To calculate the standardized cesarean delivery rate by considering the individual characteristics of puerprae, and to evaluate the medical quality of obstetrics in the hospital. Methods Medical records of 69 406 puerprae from January to December in 2016 were collected from 33 tertiary general hospitals in Shanxi province. A logistic regression model was used to construct a maternal risk adjustment model of cesarean delivery, with the area under the ROC curve (AUC) used to evaluate the goodness of fit of the model. Results Of the 69 406 puerprae, 30 881 used caesarean delivery, accounting to 44. 37% . The cesarean section rate difference was statistically significant among those of different age, nationality, conditions upon admission, whether to participate in a clinical pathway, fetus number, birth weight and maternal gestational age, as well as the severity of complications (P< 0. 001). According to the logistic model, those of older age, history of cesarean delivery, twins or triplet births, neonatal overweight, malposition, placenta previa, and those with various pregnancy complications tend to use maternal cesarean section surgery, with a goodness-of-fit of 0. 82. With risk adjusted, the ranking of actual cesarean section rate and standardized cesarean section rate varies among the hospitals. Conclusions With the factor of puerprae factor adjusted, the standardized cesarean delivery rate can eliminate risk factors of the puerprae, it is feasible to scientifically evaluate the cesarean delivery rate of the hospital′s obstetric department.

Objective:To explore the curative effect of surgical treatment for Crohn′s disease (CD), to investigate the timing of surgical intervention and the choice of surgical methods.Methods:From January 1, 2016 to August 31, 2020, at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, the clinical data of 123 patients with CD and receiving surgical treatment were retrospectively analyzed, which included the type of lesion, the location of lesion, clinical manifestation, surgical method, preoperative inflammatory and nutritional indicators, postoperative recovery of digestive tract function, and the development and treatment of postoperative complications. CD was diagnosed according to Consensus opinion on diagnosis and treatment of inflammatory bowel disease ( Beijing 2018). Patient was classitied according to the Montreal Classification. Postoperative complications were graded according to the Clavien-Dindo Criteria. Mann-Whitney U test was used for statistical analysis. Results:Among 123 patients, according to the Montreal classification, two cases (1.6%) were diagnosed at ≤16 years old (type A1), 66 cases (53.7%) were diagnosed at 17 to 40 years old (type A2), and 55 cases (44.7%) were diagnosed at >40 years old (type A3). The lesions were 52 cases (42.3%) of terminal ileum (L1) type, 20 cases (16.3%) of colon (L2) type, and 51 cases (41.5%) of ileocolon (L3) type. Four cases (3.2%) were non-stenosis and non-penetrating (B1) type, 87 cases (70.7%) were stenosis (B2) type, and 32 cases (26.0%) were penetrating (B3) type. Eighteen patients (14.6%) underwent emergency surgery due to complete intestinal obstruction (10 cases), gastrointestinal perforation (five cases), gastrointestinal bleeding (two cases), and rectovesical fistula complicated with septic shock (one case). One hundred and five patients (85.4%) received selective surgery due to poor conservative treatment effects. 51 cases (41.5%) underwent traditional open surgery and 72 cases (58.5%) underwent laparoscopic surgery. Nineteen patients (15.4%) received temporary or permanent ostomy. The preoperative C reactive protein level of patients with emergency surgery was higher than that of patients undergoing selective surgery ((39.23±24.13) mg/L vs. (11.48±2.68) mg/L), while the levels of plasma albumin (ALB) and pre-ALB were lower than those of patients receiving selective surgery ((29.90±10.60) g/L vs. (38.38±8.30) g/L, (146.00±125.49) mg/L vs. (209.06±61.19) mg/L), and the differences were statistically significant ( Z=9.603, 8.754 and 7.111, all P<0.01). During the follow-up, a total of 23 cases (18.7%) developed postoperative complications, including one case of postoperative intra-abdominal hemorrhage and underwent re-operation (Clavien-Dindo grade Ⅲ complication); four cases of anastomotic leakage after operation; six cases of postoperative paralytic ileus; 11 cases of surgical site infection, all of which were Clavien-Dindo grade Ⅱ complications, and one case of deep venous thrombosis of lower extremity. No patient with severe intraoperative complication was observed, and no patients died during the operation or hospitalization. The postoperative exhaust time of patients was (3.2±1.4) d, the time of open fluid diet was (5.8±0.8) d, the length of hospital stay was (18.0±14.1) d, and the length of postoperative hospital stay was (11.2±8.8) d. Conclusions:The concept of multidisciplinary collaboration should be emphasized in the treatment of CD. Surgical treatment can effectively control the complications and improve the quality of life of patients, but the timing of operation and the choice of surgical methods should be decided prudently after perioperative treatment, multi-disciplinary participated and regulation of the internal environment. The standardized and targeted treatments for the surgical difficulties of inflammatory bowel disease should be conducted.

Objective: To analyze the prevalence of comorbidity of spinal curvature abnormality and malnutrition among primary and secondary school students aged 10-18 years in Tianjin in 2023, so as to provide scientific basis for the combined prevention of common diseases and multiple diseases among students and the construction of school health system. Methods: In September to October 2023, 31 884 primary and secondary school students aged 10 to 18 years in Tianjin were selected using stratified cluster random sampling. Abnormal spinal curvature in children and adolescents was assessed by Sereening of Spinal Curvature Abnormality of Children and Adolescents, while stunting, wasting, overweight, and obesity were determined according to the Screening for Malnutrition among Schoolage Children and Adolescents and Screening for Overweight and Obesity among Schoolage Children and Adolescents. The χ2 test was used to compare betweengroup differences in coprevalence, and multiple Logistic regression models were used to analyze the risk of different comorbidity types in different clusters. Results: The coprevalence of spinal curvature abnormality and malnutrition among primary and secondary school students in Tianjin was 1.6%, which was higher for girls than boys (1.8%, 1.4%), higher (2.5%) for senior high schools than for junior high schools and elementary schools (2.0%, 0.5%), and higher in rural than in urban areas (2.1%, 1.1%) (χ2=9.45, 141.92, 46.94, P<0.05). Multiple Logistic regression models showed that junior high school girls had a higher risk of incorrect posture comorbid with stunting and wasting (OR=4.52, 95%CI=1.84-11.06) and incorrect posture comorbid with overweight and obesity (OR=2.67, 95%CI=1.74-4.10) than boys, and that scoliosis/sagittal spinal abnormality comorbid with stunting and wasting (OR=0.10, 95%CI=0.02-0.44) risk was lower than that of boys, senior high school girls had a lower risk of scoliosis/sagittal spinal abnormality comorbid with overweight and obesity (OR=0.27, 95%CI=0.11-0.66) (P<0.05). Conclusions The coprevalence of spinal curvature abnormality and malnutrition is specific among primary and secondary school students in Tianjin, and the comorbidity type varies by gender and education stage. There is a need to increase prevention and control of spinal curvature abnormalities in school health working, intensive screening of key populations, and timely intervention.

Objective:To evaluate the nutritional status of patients with decompensated liver cirrhosis and explore the correlation with malnutrition and the risk factors of depressed mood.Methods:190 cirrhotic patients admitted to the Department of Gastroenterology of the First Hospital of Shanxi Medical University from June to September 2023 were selected according to the inclusion and exclusion criteria. Eligible patients were divided into subgroups based on the presence or absence of malnutrition as determined by subjective global assessment (SGA). The Center for Epidemiological Studies Depression (CES-D) scale was used to assess patients' propensity for depressed mood. Relevant clinical data were also collected and analyzed.Results:A total of 185 patients were included, of which 126 were in the non-malnutrition group and 59 malnutrition group. There were significant between-group differences in terms of CES-D results, age, body mass index, platelets, D-dimer, serum sodium, third lumbar skeletal muscle index, grip strength, triceps skinfold thickness, and upper arm muscle circumference (all P<0.05). Correlation analysis showed that grip strength, triceps skinfold thickness, upper arm muscle circumference, serum sodium, and depressed mood tendency status were correlated with the development of cirrhotic malnutrition ( P<0.05). The diagnostic model for malnutrition in cirrhosis using these five indicators showed the area under the curve of 81.9%. Conclusions:Depression is closely related to the development of malnutrition in patients with liver cirrhosis. Independent risk factors for malnutrition in cirrhosis include serum sodium≤135 mmol/L, grip strength, triceps skinfold thickness, lower-than-normal upper arm circumference , and the tendency of depression , which demonstrate the combined contribution to the diagnosis of malnutrition in cirrhosis.

Objective: To investigate the effect of thapsigargin (TG) which can induce endoplasmic reticulum stress (ERS) on the replication of coxsackievirus B 3 (CV-B3). Methods: After 10 MOI CV-B3 infected HeLa cells were exposed 0.25 μmol/L TG for 3 h, 6 h and 9 h, virus RNA of HeLa cells were extracted and viral replication was evaluated by real time PCR. After 0.25 μmol/L、0.08 μmol/L and 0.025 μmol/L TG exposed, the plaque of CV-B3 was used to confirm further replication of CV-B3. To verify TG induced ERS through three signal pathway, one of among PERK, ATF6 and IRE1 inhibitors GSK2656157, AEBSF and STF-083010, and 0.25 μmol/L TG were used in HeLa cells infected with 10 MOI CV-B3, replication of CV-B3 was evaluated by qRT-PCR. Results: The stimulation of TG did not induce increase of virus replication after post-infection 3 h. However, TG induced replication of virus to increase 2.5 times after post-infection 6 h and 158.6 times after post-infection 9 h. And, the area of viral plaque was significantly increased. ATF6 inhibitors AEBSF significantly inhibited promotion of virus replication from TG. Conclusions TG can promote the replication of CV-B3 through ATF6 signal pathway.
