Objective To observe the effects of the home tele-rehabilitation guidance on activities of daily living and motor function in patients after cerebral infarction. Methods 101 cases with cerebral infarction at recovery stage were divided into control (n=50) and rehabilitation (n=51) group. The rehabilitation group received home tele-rehabilitation guidance. They were assessed with the Barthel index (BI) and the simplified Fugl-Meyer assessment (FMA) before and 3 month after treatment. Results There is no significant difference in both the BI and FMA between these groups before treatment, and the rehabilitation group improved more after treatment (P<0.05). ConclusionHome tele-rehabilitation guidance can facilitate the recovery of activities of daily living and motor function in cerebral infarction patients.

Objective:To observe the clinical effects of tuina plus Western medication for functional dyspepsia (FD) due to liver qi stagnation and spleen deficiency.Methods:A total of 72 patients in conformity with the inclusion criteria of FD were randomly divided into an observation group and a control group based upon the random number table,36 cases in each group.The control group was treated with mosapride citrate dispersible tablets,and the observation group was treated with the same tablets plus tuina.Before the treatment and 4 weeks after the treatment,the clinical symptoms,quality of life (QOL) and depression severity were observed by the scale,and were followed up two months later after the treatment for assessment of the clinical effects.Results:After the treatment and at the follow-up,the symptom scores of FD and the sores of Hamilton depression rating scale (HAMD) in both groups decreased,and the scores in Chinese version of quality of life questionnaire for functional digestive disorders (Chin-FDDQL) increased,with statistically significant differences in comparison with the same group before the treatment (all P＜0.05).In comparison between the two groups at the same time point after the treatment,the scores of FD symptoms,HAMD and Chin-FDDQL were improved better in the observation group than those in the control group,with statistically significant differences (all P＜0.05).The total effective rates at the follow-up were 91.7％ in the observation group and 75.0％ in the control group,without statistical difference between the two groups (P＞0.05).The rate of clinical cure and remarkable effect was 66.7％ in the observation group,higher than 41.7％ in the control group,it is higher in the observation group than that in the control group,with a statistically significant difference between the two groups (P＜0.05).Conclusion:Tuina plus Western medication is precise in the therapeutic effects for FD due to liver qi stagnation and spleen deficiency and can effectively relieve clinical symptoms,elevate the QOL and alleviate depression severity of the patients.Moreover,it's better than the treatment by Western medication alone in the long-term therapeutic effects.

BackgroundPosterior capsule opacification(PCO) is the main cause inducing low vision after extacapsular cataract extraction. Our previous study determined that polylysine-ethylene diamine tetraacetic acid (EDTA) (PLE) can suppress the incidence of PCO. ObjectiveThe goal of this experiment was to investigate the inhibition of polylysine-EDTA on rabbit lens epithelial cells (LECs)proliferation in vitro and the effective concentrations of polylysine-EDTA. MethodsThe anterior capsular membranes from 10 3-month-old clean New Zealand white rabbits were digested and then cultured to obtain the LECs. The second and third generation of LECs were inoculated on the 96-hole culture plate with the cell density of the 1 × 105/ml. 12.5,25.0,50. 0,100. 0 μmol/Lof PLE were added into the culture medium for 48 hours respectively,and the DMSO medium was used at the same way as the control group. The proliferation of the LECs was then detected by MTT method and the inhibitory rate of PLE on LECs growth was calculated. ResultsLECs grew at a near normal state in ≤25.0 μmol/L PLE groups,however,cultured LECs were out of shape and the numbers decreased with the weakened adhesion ability in ≥50.0 μ mol/L PLE groups. The A490 values of LECs were 0. 278±0. 013,0. 266±0. 028,0. 260±0. 022 and 0. 247±0. 012 in 12. 5,25.0,50. 0, 100. 0 μmol/L polylysine-EDTA groups respectively and were lower than 0. 311 ±0. 038 of DMSO control group( P=0. 035,0. 011,0. 009,0.013 ). The inhibitory rates of 12. 5,25.0,50. 0, 100.0 μmoL/L PLE on LECs proliferation were 10.61％ , 14.47％ , 16.40％ and 20. 58％ respectively. ConclusionsPolylysine-EDTA can inhibit the growth and proliferation of LECs in vitro at a dose-dependent manner.

Plant can produce reactive oxygen species (ROS) in normal physiological activity. However, ROS can increase dramatically by environmental stress. The increase may break the ROS balance in the plant. To control ROS levels in plants, an antioxidant system is needed to protect the cell. This paper introduced the types and functions of antioxidant enzymes, and studied the effects of plant and environmental factors on the activities of antioxidant enzymes. At last, the paper discussed the research hot fields of the effect of environmental stress on antioxidant enzymes, and gave the research strategies to the problems which happened in the studies.

Patients with late-stage cancer commonly have distant lymph node metastasis; however, poor health often contraindicates surgical treatment. Although the quality of life and overall survival for these patients are low, there is neither a consensus nor a guide for treatment. Ablation technique and surrounding tissue damage are two possible reasons for limited study of radiofrequency ablation in patients with superficial distant lymph node metastasis. Here, we report two patients treated successfully with ultrasound-guided radiofrequency ablation for superficial distant lymph node metastasis. In these patients, deionized water was injected to the surrounding tissues of the lymph node to decrease heat injury. Results from these patients suggest that radiofrequency ablation may play an important role in the treatment of patients with distant lymph node metastasis.

A fusion gene CTB-PROIN, in which Proinsulin gene was fused to the 3' end of CTB gene by a hinge peptide 'GPGP', was constructed and cloned into pET-30a(+) to obtain a prokaryotic expression vector pETCPI. Subsequently the recombinant plasmid pETCPI was transformed into E. coli stain BL21 (DE3). After induced by IPTG, the expression product was analyzed by sodium dodecyl sulphate-polyacrylamide gel (15%) electrophoresis (SDS-PAGE), and its result indicated that the recombinant protein CTB-PROIN was expressed and accumulated as inclusion bodies. The recombinant CTB-PROIN protein accumulated to the level of 25% of total bacterial proteins. After inclusion bodies was denaturalized and refolded in vitro, significant assembly of monomers had occurred, and the recombinant protein represented assembled pentamers. The results of western blotting analysis also demonstrated that the fusion protein could be recognized by the anti-CT and anti-insulin antibody, respectively. In addition, the result of the CTB-PROIN-GM1 binding assay, that the protein could bind to monosialoganglioside specifically, showed it possesed biological activity in vitro. These results provided the possibility of developing a cheaper and more efficient oral vaccine for type I diabetes using such constructs.

OBJECTIVETo evaluate the value of cryptococcal latex agglutination test in the diagnosis and treatment of cryptococcal meningitis in children.

METHODSThe clinical data of 10 children with cryptococcal meningitis were retrospectively studied. Cryptococcal meningitis was confirmed based on clinical manifestations, India ink stain, cryptococcal latex agglutination test or cryptococcal culture. The outcome of antifungal treatment and the changes of latex agglutination test titer were followed up for 2 to 4 years.

RESULTSLatex agglutination test and/or India ink stain were positive (titer 1 : 64-1 : 1024) in 8 patients in the first examination of cerebrospinal fluid. In the other 2 patients, latex agglutination test was positive (titer 1 : 256) in the fourth examination of cerebrospinal fluid in one, and India ink stain was positive in the eleventh examination in the other. After antifungal treatment, six patients were cured, two patients died, and two patients were lost to follow-up. The positive cryptococcal latex agglutination test (titer 1 : 2-1 : 16) was seen respectively in six, three, two and one cured patients 6 months, 1 year, 2 years and 4 years later.

CONCLUSIONSThe cryptococcal latex agglutination test of cerebrospinal fluid is valuable for the quick and early diagnosis of cryptococcal meningitis; however, the decision of withdrawal of antifungal treatment should not rely on the results of the test.

OBJECTIVETo investigate the incidences of urea cycle defects (UCDs) in the patients with hyperammonemia and study their etiology, clinical and laboratory features.

METHODSIn the past 7 years, 26 cases (10.2%) of UCDs were detected from 254 patients with hyperammonemia. The etiological diagnoses were made by blood amino acids analysis, urinary organic acid analysis and blood acylcarnitine profile analysis. Three patients with citrullinemia type II were further confirmed by liver pathological analysis and gene diagnosis.

RESULTSAmong 26 cases with UCDs, 15 had ornithine transcarbamylase (OTC) deficiency, 5 had citrullinemia type I, 3 had citrullinemia type II and 3 patients had arginemia. The age of onset of the patients ranged from 3 days to 13 years. Three cases (11.5%) developed hyperammonemic encephalopathy during neonatal period. Thirteen (50.0%), 7 (26.9%) and 3 (11.5%) cases developed clinical symptoms at the age of 1 to 12 months, 1 to 3 years and 6 to 13 years, respectively. Positive family history was found in 11 cases (42.3%). Among 26 patients with UCDs, 9 (34.6%) were hospitalized with the complains of seizures, psychomotor retardation, vomiting and unconsciousness, 8 (30.8%) with recurrent vomiting, headache and coma, 6 due to liver dysfunction. Intrahepatic cholestatic jaundice was found in 3 patients with citrullinemia type II. Blood ammonia ranged from 58 to 259 micromol/L on their first visit to our hospital. Twenty cases (76.9%) had liver dysfunction, 4 patients (15.4%) were diagnosed postmortem. Twenty-one patients got treatment and were followed up. Among them, 7 cases died of hyperammonemic encephalopathy or upper alimentary tract bleeding. Clinical improvement was observed in 14 cases. A boy with OTC deficiency who received a partial liver transplant from his mother showed normal general condition for two years.

CONCLUSIONSUCDs are the most frequent causes of congenital hyperammonemia. In this study, 26 patients (10.2%) with UCDs were identified from 254 patients with hyperammonemia resulting in encephalopathy and liver dysfunction. Early diagnosis and treatment can contribute a lot to improve the prognosis of the patients. Blood ammonia assay and further etiological analysis should be considered in the differential diagnosis of neurological and hepatic abnormality.

OBJECTIVETo study the "hot spot" of BRCA1/2 gene mutations in Chinese mainland breast cancer population.

METHODSThe known BRCA1/2 gene mutations in author's previous studies were reanalyzed by denaturing high performance liquid chromatography and DNA sequencing method in 177 patients with early onset breast cancer or affected relatives and 426 sporadic breast cancer patients from four breast cancer centers in China.

RESULTSThree cases were found with BRCA1 5589del8 mutation out of 247 hereditary-predisposing breast cancer patients (70 patients in previous study and 177 patients in current study) and 2 cases with BRCA1 5589del8 mutation out of 426 sporadic breast cancer patients. They had similar even same haplotype.

CONCLUSIONBRCA1 5589del8 mutation is likely to be the "founder mutation" in Chinese population, but it should be confirmed by further studies.

OBJECTIVETo explore the way of promoting the efficacy of surgical treatment for ventricular septal rupture (VSR) after acute myocardium infarction in terms of perioperative and long term survival.

METHODSThe clinic data of 37 VSR cases underwent surgical treatment from October 1994 to October 2007 were analyzed retrospectively. There were 24 male and 13 female, and the age was (63.4 +/- 7.6) years old. The whole group was divided into the VSR repair plus revascularization group (group A, 26 cases) and simple VSR repair group (group B, 11 cases).

RESULTSThere were 4 operative deaths in group A (15.4%), 7 deaths in group B (63.6%), P = 0.006. With the follow-up of (34.0 +/- 29.8) months ranged from 2 to 103 months of the 26 operational survivors, there were 5 late deaths, of which 2 deaths in group A and 3 deaths in group B. According to the Kaplan-Meier survival curve, the actuarial survival rate at 6 to 8 year was (64.3 +/- 21.0)% for group A and the actuarial survival rate at 4 year was (25.0 +/- 21.7)% for group B, P = 0.011. Of the 21 mid-long term survivors, 17 cases were in NYHA class I to II and 4 cases in NYHA class III to IV. There were 4 cases suffered from VSR recurrence. According to Logistic regression, the risk factors for the early death were not adoptive of revascularization, cardiogenic shock and emergency surgical procedure, while the risk factors for late death were not adoptive of revascularization and low cardiac output after the procedures.

CONCLUSIONSVSR repair plus revascularization could improve the perioperative and mid-long term survival for the surgical treatment of VSR. The appropriate timing and procedures of the surgical operation are very important to promote perioperative survival and to prevent VSR recurrence.
