Objective: To investigate the prevalence of osteoporosis (OP) and its influencing factors among people aged 60 years and above, so as to provide insights into OP prevention and treatment among the elderly. Methods: People aged 60 years and above who underwent physical examinations were selected from Hangzhou First People's Hospital from January to October 2023. Demographic information, lifestyle and physical examination data were collected through field surveys and hospital information systems. Bone density was measured by dual-energy X-ray densitometer, and OP was diagnosed with reference to the Guidelines for the Diagnosis and Treatment of Primary Osteoporosis (2022). Factors affecting the OP were identified using a multivariable logistic regression model. Results: A total of 482 participants were included and had a mean age of (69.10±6.52) years. There were 217 men (45.02%) and 265 women (54.98%). The prevalence of OP was 43.36%. Multivariable logistic regression analysis identified gender (women, OR=3.791, 95%CI: 1.726-8.314), age (70 to 79 years, OR=1.260, 95%CI: 1.018-1.559; 80 years and above, OR=3.083, 95%CI: 1.546-6.147), body mass index (≥24 kg/m2, OR=0.358, 95%CI: 0.205-0.626), family history of fracture (OR=1.475, 95%CI: 1.073-2.030), diabetes (OR=1.626, 95%CI: 1.109-2.382), regular exercise (OR=0.457, 95%CI: 0.287-0.726), intake of milk products (OR=0.511, 95%CI: 0.335-0.780), intake of calcium supplements (OR=0.473, 95%CI: 0.287-0.778) and vitamin D deficiency (OR=2.132, 95%CI: 1.309-3.473) as factors affecting OP. Conclusion The prevalence of OP is associated with gender, age, body mass index, family history of fracture, diabetes, diet and vitamin D deficiency.

Objective:To explore the effect of group psychotherapy on damage of theory of mind (TOM) in patients with early-onset schizophrenia.Methods:Totally 60 patients with early-onset schizophrenia were included and divided into the intervention group (n ＝ 30) and the health education group (n ＝ 30).The patients in the intervention group were offered 10 twice a week 2-hour sessions of group psychotherapy,and those in the control were offered group health education twice a week.All participants completed baseline measures and post-intervention measures with the Eye Emotion Recognition and Theory of mind Picture-sequencing Task (TOM-PST).Results:Totally 23 patients in the intervention group and 29 patients in the health education group finished the post-intervention measures.After 5-week intervention,subscores of sad and fear and total score of emotion recognition,total score of TOM-PST,understanding first order error belief,second order error belief,third order error belief,sense of reality,detecting fraud compared to baseline had statistically significant difference in intervention group.In health education group,subscores of joy emotion recognition,understanding first order error belief,third order error belief,total score of TOM-PST compared to baseline had statstically significant difference.The patients with group psychotherapy got higher scores of total score of TOM-PST and understanding second order error belief and third order error belief than the health education group after 5-week intervention (P ＜ 0.05).Conclusion:This study suggests the group psychotherapy could partially improve theory of mind with early-onset schizophrenia,and promote the recovery of social cognition.

Objective To observe the clinical curative effect of tripterygium polyglycoside combined with cozaar in elderly patients with IgA nephropathy (IgAN) and its influence on expressions of TGF-β1,PAI-1 and VEGF.Methods Eighty elderly patients with IgA nephropathy in Jiaxing Hospital of Armed Police Zhejiang Corps from April 2011 to January 2016 were selected and randomly divided into the control group and observation group,40 cases in each group.The two groups received the routine treatment of chronic basic diseases and took oral cozaar.On this basis the observation group took tripterygium polyglycoside for continuous 12 months.Urine protein,serum creatinine (Scr),blood urea nitrogen (BUN),plasma Alb,urine TGF-β1,PAI-1 and VEGF levels before treatment and at 3,6,12 months after treatment were compared between the two groups.The occurrence situation of adverse reactions was recorded.Results The 24 h urinary protein levels at 3,6,12 months after treatment in the two groups were decreased,moreover the 24 h urine protein level at each time point in the observation group was lower than that in the control group,the difference was statistically significant (P<0.05).The levels of Scr,BUN,urine TGF-β1,PAI-1 and VEGF after treatment in the two groups were decreased compared with before treatment,while the Alb level was increased compared with before treatment,moreover the levels of Scr,BUN,urine TGF-β1,PAI-1 and VEGF in the observation group were lower than those in the control group,while the Alb level was higher than that in the control group,the difference was statistically significant (P<0.05).The observation group appeared 2 cases of leukopenia,1 case of liver dysfunction and no serious adverse reactions occurred.Conclusion Tripterygium polyglycoside combined with cozaar has a significant therapeutic effect on elderly patients with IgAN,can significantly reduce urinary protein and protect renal function,moreover its clinical use is safer.Its efficacy may be related to reducing the expression levels of TGF-β1,PAI-1 and VEGF.

In order to explore the role of acetylcholine in the pathogenesis of Parkinson's disease (PD), the changes in the concentration of acetylcholine (Ach) in the striatum, the apoptosis of substantia nigra cells, the ultrastructure and the changes of Nissl cells in rats during the morbidity of PD, and the corresponding behaviors in rats with PD were observed. Rat PD model was established by using the modified Thomas method. Eighty-one rats were randomly divided into normal control, sham operation and PD groups and their behavior features were observed at post-operative day (POD) 7, 14 and 21 as three subgroups (n=9 each). The concentration of Ach in the striatum was determined by using high-performance liquid chromatography. The apoptosis of substantia nigra cells was assayed by using TUNEL method. The ultrastructural changes in the substantia nigra were observed under the electron microscopy, and the survival of neurons in the substantia nigra area was examined by using Nissl staining. In PD group at POD 7 to 21, the damage in the substantia nigra area was gradually aggravated, the concentration of Ach, apoptosis rate and turns of rotation were gradually increased, and the number of Nissl cells was gradually reduced over the time as compared with the normal control and sham operation groups (all P<0.05). It was concluded that there exist dynamic changes in Ach concentration, ethology and apoptosis of the substantia nigra cells during the morbidity of PD, suggesting the contribution of apoptosis to the morbidity of PD, and critical role of Ach in the pathogenesis of PD.

Objective To investigate the clinical efficacy of laparoscopic Soave's surgery for the treatment of congenital Hirschsprung's disease in infants (age ＜ 2 months).Methods The clinical data of 368 infants with congenital Hirschsprung's disease who received laparoscopic Soave's surgery at the Children's Hospital of Xuzhou City from June 2005 to June 2012 were retrospectively analyzed.Three Trocars with diameter of 0.5 cm were used.The colic ligament was freed and the mesentery was ligated laparoscopically,then the rectal mucosa was stripped for 5-7 cm in length,and was pulled out through the rectal muscle sheath.Patients were followed up via out-patient examination at postoperative month 1,3,6,12 to learn the frequency of defecation,constipation and anal stenosis.The follow-up was ended in June of 2013.Results Two patients were converted to open surgery,and the remaining 366 patients received laparoscopic surgery successfully,with no incidence of wound infection.The operation time,volume of blood loss and duration of hospital stay were (100 ±20)minutes,(5.4 ± 1.5) mL and (7.3 ± 1.5) days,respectively.The average time for antibiotics usage was (3.5 ± 1.6) days and the time for infusion was (3.8 ± 1.4) days.All the infants were followed up,and the mean time for postoperative follow-up was 4.5 years (range,1.0-8.0 years).Eleven patients were complicated with Hirschsprung's disease associated enteritis,7 patients with constipation,5 with anal stenosis,4 with fecal pollution.The condition of the infants was improved after conservative treatment.Conclusion Laparoscopic Soave's surgery is suitable for the treatment of congenital Hirschsprung's diseases in infants aged under 2 months,it has the advantages of small trauma,quick recovery,better cosmetic effects and few complications.

Objective To investigate the influence of pregnancy and delivery on maternal graft and newborns after renal transplantatior.Method Two cases of successful pregnancy and delivery after renal transplantation were retrospectively analyzed and the literatures were reviewed.Result The first recipient received the immunosuppressive treatment,which was based on the mycophenolate after renal transplantation.Three years after transplantation,the recipient had the requirement of pregnancy,but there was no pregnancy without contraception for over one year.On the next month after the myocphenolate-based immunosuppressive regimen changed to the purine-based,B ultrasound revealed follicular growth,ovulation and pregnancy.Caesarean section was performed at 37 gestational weeks and a body was delivered.The weight of the boy was 2 750 g,and the Apgar scores of the newborn were 10.The second recipient received triple immunosuppressive therapy (cyclosporin A + azathioprine + methylprednisolone),and got natural pregnancy 4 years after renal transplantation.The recipient was hospitalized due to the increased blood pressure and reduced fetal heart rate at 33 W+2 gestational weeks,and discharged after treatment.Caesarean section was performed at 38 W+1 gestational weeks,the weight of the boy was 3 000 g,and the Apgar scores of the newborn was 10.After follow-up for 8 years old,there was on abnormity of the function of the transplanted kidney and the growth of the newborns.Conclusion Successful pregnancy and delivery are possible in renal transplant recipients with normal renal function.Regulating the immunosuppressive regimen appropriately,and treating the complications of pregnancy effectively can obtained the satisfactory outcome of pregnancy.
