Objective To explore the effect of heterosexual interaction training on rehabilitation in first-episode schizophrenic patients. Methods 246 patients of first-episode schizophrenic were divided into the study group and the control group with 123 cases in each group at random. Both groups were treat-ed with conventional pharmacotherapy under the orders of physicians in hospital. For the study group,both the male patients and the female patients took part in entertainment treatment activities,eating and interaction training together during the day, then they lived separately at night. Two groups were evaluated with BPRS and ITAQ before treatment and at the 2nd, 4th, 6th, and 8th week after treatment. Results The BPRS scores of the study group were significantly lower than the control group after 4th, 6th,and 8th week. The ITAQ scores of the study group were significantly higher than the control group after 4th, 6th,and 8th week. Conclusions The application of heterosexual interaction training in schizophrenic patients can alleviate illness condition, improve treatment compliance and rehabilitation.

Objective To evaluate the significance of p53 protein expression of hepatocellular carcinoma (HCCs) cells after transcatheter arterial chemoembolization(TACE). Methods A total of 136 patients with HCC underwent liver resection. One to five courses of TACE prior to liver resection were performed in 79 patients (TACE group), in which one to four courses of chemotherapy alone were performed in 11 patients (Group A), one to five courses of chemotherapy combined with iodized oil were performed in 33 patients (Group B), one to three courses of chemotherapy combined with iodized oil and gelatin sponge were performed in 23 patients (Group C), and one to three courses of chemotherapy combined with iodized oil, ethanol and gelatin sponge were performed in 12 patients (Group D). The other 57 patients only received liver resection (non-TACE group). The extent of apoptosis was analyzed by transferase-mediated dUTP nick end labeling (TUNEL) staining. The expressions of Bcl-2, Bax, Ki-67 and PCNA proteins were detected by immunohistochemical method. Results p53 protein expressions of trabecular and clear cell HCCs were significantly lower than those of pseudoglandular, solid, poorly differentiated or undifferentiated and sclerosis HCCs (P

Objective To observe the effects of puhnonary rehabilitation on the symptoms and quality of life of persons with chronic obstructive pulmonary disease (COPD).Methods COPD patients were recruited from a hospital and community health centers and given pulmonary rehabilitation in the community.The rehabilitation program included health education and nutrition guidance,medication,breathing exercises,and physical exercise.Each patient was followed up every 4 weeks by telephone.The outcome measures included pulmonary function (FEV1％,FEV1/FVC％),St George's questionnaire (SGRQ),the Medical Research Council scale (MRC),Borg scoring,evaluation of anxiety and depression,the six-minute walk test (6MWT),and an evaluation of nutritional status.All of the patients were observed for one year.Results A total of 85 patients completed the program and were included in the final statistical analysis.There was no difference in FEV1 ％ before and after rehabilitation.Six-minute walking distance improved significantly in statistical terms but the average increase was only from (416.1 ±99.84)m to (437.51 ±116.17)m.The SGRQ scores decreased by an average of 4.8 points after a year of rehabilitation,with significant improvements among the moderately and severely impaired.Incidents of COPD exacerbation also decreased significantly.Patients with a low body mass index had the greatest SGRQ score improvments.Few patients showed depression or anxiety in this research population.Conclusions Pulmonary rehabilitation in the community can improve exercise tolerance and the quality of life for persons with COPD,reducing incidents of acute exacerbation.Patients may benefit from such pulmonary rehabilitation regardless of disease severity.The compliance was good despite the infrequent monitoring.Pulmonary rehabilitation in the community is worthy of more widespread use.

Objective To study the body composition of public security staffs and to prevent sub-health condition positively. Methods Body compositions of 771 public security staffs were measured and analyzed with bioelectrical impedance analytic process (BIA). Results The male public security staffs had obviously lower body fat percentage (P< 0.01) but higher body mass index and obesity (P<0.05) than female public security staffs. Both male and female public security staffs fad the highest content of fat in the lower limbs. The body part ranked the second place, followed by the upper limbs. Measured by body-fat percentage(BF%), the obesity rate of the male and female staffs was 10.08% and 45.59% respectively. Measured by body mass index (BMI), the hypergravity rate of the male and female staffs was 44.09% and 20.59% respectively; and the obesity rate of the male and female staffs was 8.35% and 0.74% respectively. Measured by obesity degree (OBD), the hypergravity rate of the male and female staffs was 21.73% and 4.41% respectively; and the obesity rate of the male and female staffs was 11.65% and 1.47% respectively. Conclusion Public security staffs should pay attention to their over-weight and hyper-fat level. Proper dict and body exercise are needed.

Objective To investigate a periosteal autograft method to repair major defects of joint cartilage in rabbits of different ages. Methods Major cartilage defects of 52 rabbits aged 4 to 52 weeks were repaired with free periosteal grafts and the results were compared in the study. The regenerated cartilage by the cambium of periosteum growing up to the cavity of joint and that growing down to the cancellus of femur were also compared. Results The macroscopical and histological observations at different intervals showed that in young and adult rabbits the grafts could develop into cartilages to repair the major cartilage defects. In adult rabbits the newly formed cartilage was the same as the normal cartilage in thickness and histology. There was no difference between the cambium growing up to the cavity and that growing down to the cancellus. Conclusions Periosteum possesses chondrogenic potential and can be used to repair the cartilage defects. Different directions of chondrogenesis leads to no significantly different outcomes. In adult rabbits the newly formed cartilage can develop into a normal one.

Objective To discuss the safety and feasibility of percutaneous transhepatic biliary preset implantation of after-loading radiotherapy catheter in treating bile duct carcinoma of ampulla.Methods A total of 10 patients with carcinoma of ampulla were collected.After percutaneous transhepatic biliary stent implantation was accomplished,the after-loading radiotherapy catheter was inserted via the guide wire.Based on the lesion's location,the positioning of both the catheter tip and the simulation radioactive source implanted through catheter was conducted.Each time before irradiation,the positions of the catheter and the radioactive source were reset under CT or fluoroscopic guidance in order to ensure that the lesion could get adequate internal irradiation dose.Results Percutaneous transhepatic biliary implantation of after-loading radiotherapy catheter and the positioning of simulation radioactive source were successfully accomplished in all 10 patients,and the total internal irradiation dose was completed within 5-7 days after catheter implantation.No severe complications occurred during the whole therapeutic process.Conclusion The technology of percutaneous transhepatic biliary preset implantation of after-loading radiotherapy catheter is safe and feasible,it carries high success rate with less complications.This therapy can improve the patency rate of biliary stent,and,as a palliative treatment,it is suitable for patients with carcinoma of ampulla.This treatment is worthy of application and promotion.

Aim To prepare the novel pyridostigmine bromide nanoemusion(PPNE)and study its release in vitro, and to investigate the intestinal absorption. Methods Pyridostigmine bromide (PB)and PPNE were tested by HPLC in pH 1 .2 HCl,pH 6.8,pH 7.4,pH 7.8 PBS.Rat single pass intestinal perfusion method was employed to investigate the absorption mechanism of PB and PPNE.Results PB release rate was faster than PB in the four release media;the intes-tinal absorption rate constant(Ka )and apparent perme-ability coefficient(Papp)of PPNE were increased in the duodenum,jejunum,ileum and colon segments.PB and PPNE had significant difference in the duodenum, jejunum,ileum and colon segments by t test (P <0.05).Conclusions PPNE can improve the bioavail-ability of drugs,increase the drugs permeability,sig-nificantly improve the absorption of the drugs in the in-testinal segments. PPNE has obviously sustained effects.

Aim To observe the optimal temperature and optimal pH of uricase-catalase liposomes(UCALP) and free uricase(UAE), and study the abilities of UCALP to reduce uric acid and hydrogen peroxide in mice with hyperuricemia.Methods UCALP were prepared by reverse phase evaporation, optimal temperature and optimal pH of UCALP and UAE were determined, respectively.Mouse model of hyperuricemia was established by intraperitoneally injection of uric acid, and the model mice were intravenously injected UCALP and UAE, respectively, then the serum concentration of uric acid and hydrogen peroxide in mice at different time points were measured by the assay kits, respectively.Results Optimal temperature of UCALP and UAE was 40℃, and optimal pH was 8.0 and 8.5, respectively.UCALP could more significantly lower uric acid level of hyperuricemia mice than that of UAE, and the concentration of hydrogen peroxide in UCALP group was lower than in UAE group.Conclusion UCALP can effectively decrease the level of uric acid and control the level of hydrogen peroxide in mice with hyperuricemia.

Objective To evaluate the surgical treatment of the acute posterolateral complex(PLC)injuries of knee joint and then observe the clinical outcome.Methods Twelve cases(12 knees)of acute PLC injuries were treated from May 2006 to October 2008.Patients' age ranged from 23 to 47 years old,average 31 years.There were 9 males and 3 females.Rebuild the anterior cruciate ligament(ACL)and posterior cruciate ligament(PCL)under arthroscope and then,locally suture the PLC injuries sites on those patients with PLC avulsion fraction.If there is PLC rupture,then locally suture the injury sites plus PLC reconstruction.Knee functions were evaluated by IKDC and Lysholm score.Results All patients were followed up for 12-18 months(mean,13.3 months).The preoperative range of motion was 118.00°±6.77°,which was 130.75°±3.05° after surgery.KT-1000 arthrometer measurement showed that the average posterior translation improved from(14.85+1.83)mm preoperatively to(4.18±1.88)mm postoperatively.Seven cases were normal(A grade),3 cases were nearly normal(B grade),1 abnormal(C grade),and 1 severely abnormal(D grade)according to IKDC standard.The preoperative Lysholm joint function score was 35-44,average 38.83 ±3.16,which was 79-91,average 84.92±3.73 after surgery.Conclusion To those acute PLC injuries with avulsion at the ligament extremities,locally suture should be taken.But for those with PLC rupture at the mid part of ligament,locally suture the injury sites plus PLC reconstruction helps get satisfactory outcome.
