ObjectiveTo investigate the social support status and influencing factors of schizophrenics in remission in Northeast Sichuan， and to provide ideas for improving their social support. MethodsFrom May to September 2020， a total of 533 patients who met the diagnosis criteria of the International Classification of Diseases， tenth edition （ICD-10） for schizophrenics in remission at the mental health institutions in Guangyuan， Bazhong and Dazhou cities were selected for the survey， and patients were assessed by self-made demographic and clinical data inventory and Social Support Rating Scale （SSRS）. Then the social support status of schizophrenic in remission and influencing factors were analyzed， meantime， the impact of the second round reimbursement policy of medical insurance benefits on their social support was addressed particularly. Results①The SSRS total score， objective support， subjective support， and utilization of support scores of schizophrenics in remission were lower than those of the national norm （t=5.065~30.382， P<0.01）. ②Univariate analysis showed that SSRS score was relatively high among patients with female gender （t=-3.632）， retired status （F=5.951）， married status （F=5.951）， spouse as primary caregiver （F=23.841）， annual household income >5 000 yuan （F=15.892）， patient's economic income （t=4.083）， and outpatient or online follow-up （F=3.954）， with statistically significant differences （P<0.05 or 0.01）. ③The total and dimensional scores of SSRS in patients with access to the second round medical insurance reimbursement were significantly higher than those without （t=10.195~25.103， P<0.01）. ④Multiple linear regression analysis denoted that gender， work status， marital status， primary caregivers， annual family income， economic income， follow-up visits and the second round medical insurance reimbursement were the factors influencing social support status of schizophrenics in remission （β=0.201~2.115， P<0.05 or 0.01）. ConclusionThe social support of schizophrenics in remission in Northeast Sichuan is below the national average， furthermore， their social support levels are affected by the gender， work status， marital status， primary caregivers， annual family income， economic income， follow-up visits and the second round medical insurance reimbursement， and the second round medical insurance reimbursement may ameliorate the social support status of patients.

Objective To investigate the effects of aerobic exercise on cardiorespiratory function in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS).Methods A total of 84 patients with OSAHS were randomly divided into a control group and an aerobic exercise group (42 in each group).The control group was given only training in the activities of daily living (ADL).The acrobic exercise group was given ADL training combined with aerobic exercise training.The regime was maintained for 16 weeks.Each patient's VO2max,maximum heart rate (HRmax),exercise time to exhaustion,6-minute walking distance and quality of life (QOL) were evaluated before and after treatment.Results VO2max,HRmax,VO2max/HRmax,maximum exercise time,6-min walking distance and QOL all increased significantly more in the aerobic exercise group compared with the control group.Conclusion Aerobic exercise training can significantly improve cardiorespiratory function in patients with OSAHS.

Objective To compare the short-term clinical effect of the foam sclerotherapy combined with Melilotus Extract Tablets vs foam sclerotherapy alone in treating varicose veins of the lower extremities.Methods A retrospective cohort study was carried out in 120 cases receiving foam sclerotherapy in the Invasive Technology Department of Panyu District Central Hospital.Seventy-two patients in trial group wore graduated compression stockings and received oral use of Melilotus Extract Tablets after the operation,while 48 cases in the control group only wore graduated compression stockings after the operation.The follow-up for the two groups lasted for 3 months.We recorded the relief of symptoms (pain,soreness and distention) and physical signs (edema,hyperpigmentation,ulcer) after the operation.The grading levels of clinical-etiology-anatomic-pathophysiologic classification system (CEAP) for lower limb venous disease,venous clinical severity scores (VCSS) and disease quality-of-life questionnaire CIVIQ scores were observed before and after the operation.Results (1) Three months after the operation,the illness state of the two groups was improved to certain degree,and the differences of CEAP grading levels were insignificant(P ＞ 0.05).(2) VCSS and CIVIQ scores of the two groups were improved after the operation (P ＜ 0.01 compared with those before the operation),and the trial group had better effect on improving CIVIQ scores than the control group (P ＜ 0.01).(3) The successful rate of the trial group was 88.89％,and that of the control group was 81.25％,the difference being insignificant (P ＞ 0.05).(4) Time for obvious relief of lower limb symptom in the trial group was shorter than that in the control group (P ＜ 0.05),but the time for hyperpigmentation and ulcer disappearing as well as the medical expenses in the trial group did not differ from those in the control group (P ＞ 0.05).Conclusion Foam sclerotherapy combined with Melilotus Extract Tablets is effective,safe and economical for the treatment of varicose veins of the lower extremities,and its efficacy is superior to foam sclerotherapy alone.

The clinical features and lung CT findings of 174 heart failure patients,including 85 cases with normal left ventricular ejection fraction (LVEF) and 89 cases with reduced LVEF were reviewed.Patients with normal LVEF had a higher proportion of hypertension,diabetes and obesity than patients with normal LVEF; and cough and dyspnea were more common.The lung CT findings in patients with normal LVEF were frequently presented as interstitial lung edema,increased pulmonary texture,subpleural line,Kerley lines and diffuse ground-glass opacity.Patients with reduced LVEF had a higher proportion of coronary heart disease and clinical manifestations of acute left heart failure,and central alveolar edema presented in lung CT images.Results suggest that heart failure patients with normal LVEF usually have longer clinical history and occult symptoms,and have a different lung CT imaging features from those in heart failure patients with reduced LVEF.

This study was aimed to investigate the action mechanism ofHypoxis Hemerocallidea (African Potato, AP) on the AMPK signal pathway of skeletal muscles in diabetic rats. Among 40 male SD rats, 10 rats were used as the normal group, and the other 30 rats were fed with high-fat food for one month, and then injected with STZ for the model establishment. After the successful model establishment, rats were divided into the model group, pioglitazone hydrochloride group and the AP group. Intragastric administration was given for 5 weeks in each group. Then, the skeletal muscle tissues were embedded and sliced for immunohistochemistry test. The protein expression of p-AMPKα, p-AS16 and GLUT4 in skeletal muscles was detected by western blot. The 100 mmol·L-1 glucose was used in the establishment of C2C12 skeletal muscle cells insulin resistance model. AP drug-containing serum was used in the establishment of the treatment group. The control group was the normal cells. Glucose consumption, cell proliferation, SOD content, and MDA content were detected. And the protein expressions of p-AMPKα, p-AS160, GLUT4 were detected with the western blot and RT-PCR. The results showed that compared with the normal group, AP can up-regulate p-AMPKa protein express (P < 0.01), increase skeletal AS160 phosphorylation level (P < 0.01), and up-regulate the GLUT4 level (P < 0.01). Compared with the normal group, the high glucose caused the decrease of C2C12 skeletal muscle cell activity and the decrease of glucose consumption (P < 0.05), decrease of SOD, increase of MDA (P < 0.01), and the decrease of p-AMPKα, p-AS160, GLUT4 protein expression (P < 0.01). After 48 h intervention, the SOD of C2C12 skeletal muscle cells in the AP drug-containing serum group was significantly increased (P < 0.01), the MDA content was decreased (P < 0.05), the AMPKa and AS160 phosphorylation levels were increased (P < 0.01), the GLUT protein expression was increased (P < 0.01). It was concluded that the induced AMPKa and AS160 phosphorylation promoted GLUT 4 expression may be one of the action mechanism of insulin resistance of skeletal muscles in diabetes.

Objective:To evaluate the immunogenicity of recombinant factor H binding protein(fHBP) by detecting serum antibody titer and serum bactericidal antibody test (SBA).Methods:fHBP sequence was selected and synthesized, connected to plasmid pET43.1a, transformed to Escherichia coli BL21(DE3), and expressed two recombinant fHBP proteins, included two subfamilies, fHBPA and fHBPB. After purification, the recombinant fHBP proteins were immunized to rabbits and mice. The immune antiserum titer and the bactericidal titer to epidemic strains of meningococcal bacteria group B were measured by ELISA and SBA respectively. Results:The antiserum titer of fHBP immunized rabbits was greater than 2.0×10 6, and that of immunized mice was not less than 1.0×10 6. fHBP immunized rabbit serum had bactericidal titer more than 1∶128 to 41 strains A subfamily and 20 strains B subfamily in the SBA against 69 endemic strains, and there was no cross-protection between the subfamily bacteria. The bactericidal titers of mouse serum immunized fHBPA to strains A subfamily such as Nm210902 Nm211009、Nm450522 were 1∶1 024, 1∶608、1∶861, to Nm510703、Nm311304、Nm431002 were 1∶234、1∶861、1∶430 respectively, and mouse serum immunized fHBP B to strains B subfamily Nm311302、Nm311304、Nm431002 were 1∶876、1∶274、1∶1858, all of three strains were positive in bactericidal titers. Conclusions:the titer of fHBP antiserum was higher than 1.0×10 6, the bactericidal titer was no less than 1∶128 to 61 epidemic strains, and it has a 94.2% protective effect on 69 meningococcal epidemic strains group B.

This article was aimed to study the effect ofQiwei granules on the podocyte in KK-Ay mice kidney. The 28 8-week-old male KK-Ay mice were randomly divided into the model group, low-dosage, middle-dosage and high-dosageQiwei granule group. Eight C57BL/6J mice were used as the normal control. The general conditions, blood glucose and 24 h albuminuria were recorded in the experiment. After 10-week treatment, renal indexes including serum creatinine and urea nitrogen were measured. The kidneys of mice were collected and measured. The hematoxylin and eosin (HE), Masson’s Trichrome, and periodic acid-Schiff (PAS) were used on renal tissues of mice. The immunohistochemical staining for WT-1 was made. Software analysis was combined in the calculation of renal podocyte amount. Western blot was used in the detection of nephrin protein expressions in the kidney of mice. RT-PCR was used in the detection of nephrin mRNA expression. The results showed that compared with the model group, the body weight, blood glucose, 24 h albuminuria and the serum creatinine were obviously decreased after 10-week treatment ofQiwei granules. It can effectively improve the glomerular mesangial proliferation and preserve the podocyte number. Meanwhile, after the treatment ofQiwei granules, the nephrin protein expression and mRNA expression were obviously higher than the model group. It was concluded thatQiwei granules probably managed nephrin expression to improve the podocyte injury in the diabetic nephropathy of KK-Ay mice.

Objective To explore the preoperative predictors of lymphovascular invasion(LVI)in patients with advanced gastric cancer,and establish the corresponding nomogram prediction model and conduct internal validation.Methods A total of 246 cases of advanced gastric cancer who underwent surgical resection in the Department of Gastrointestinal Surgery of Hengshui People's Hospital from January 2018 to December 2021 were selected.Patients were divided into the LVI positive group and the LVI negative group according to postoperative pathological diagnosis.The age,gender,tumor differentiation,tumor size,tumor site,Borrmann classification,Lauren's classification,cT stage,cN stage and systemic immune-inflammation index(SII)of patients were collected and compared between the two groups.The predictors that were statistically different between the two groups were subjected to multivariate Logistic regression and further developed into a visual prediction model.Bootstrap method was applied for internal validation of the prediction efficiency of the model.Results The differences of tumor size,Borrmann classification,tumor differentiation,Lauren classification,cT staging,cN staging and SII were statistically significant between the two groups(P＜0.05).Multivariate Logistic regression analysis showed that tumor size(OR=2.184,95%CI:1.224-3.898),Borrmann classification(OR=2.517,95%CI:1.294-4.896),cT staging(OR=1.860,95%CI:1.045-3.308),cN staging(OR=1.816,95%CI:1.004-3.285)and SII(OR=1.001,95%CI:1.000-1.002)were independent predictors of LVI in advanced gastric cancer.A preoperative nomogram prediction model for advanced gastric cancer LVI was developed based on results of multivariate analysis.By internal validation,the area under curve(AUC)value of the subject operating characteristic(ROC)curve of the nomogram was 0.735,which was higher than that of tumor size(0.599),Borrmann staging(0.564),cT staging(0.604),cN staging(0.582)and SII(0.615),respectively.The calibration curve showed that the probability of predicted LVI by the nomogram was in a good agreement with the probability of actual LVI occurrence.The Hosmer-Lemeshow test showed good model fit(χ2=4.387,P=0.821).Conclusion The established nomogram prediction model can help to predict the probability of LVI in advanced gastric cancer preoperatively,which can provide a guideline for clinical individualized treatment.
