Objective To explore the effective method on the knee osteoarthritis (KOA) of stroke patients.Methods Twenty-four stroke patients with KOA were randomly divided into the treatment group and control group with 12 cases in each group. All patients received facilitation technique exercise, the patients in the treatment group were added with an extra complex therapy of electronic acupuncture, physical and exercise thepapies. All patients of two groups were assessed with visual analogous score (VAS) and Fugl-Meyer Motion Scale (FMMS) before treatment and one course after treatment.Results After treatment, the scores of VAS and FMMS of the patients in the treatment group were significantly better than that in the control group ( P<0.01).Conclusion Multidisciplinary rehabilitation including electronic acupuncture, physical, and exercise is efficiancy to KOA of stroke patients.

Objective To evaluate the blood supply features and effectiveness of arterial chemoembolization for pedunculated hepatocellular carcinoma.Methods Angiography and chemoembolization via supplying blood arteries of tumor were performed in five patients with pedunculated hepatocellular carcinoma.Interventional procedure was carried out with tumor vascular infusion of 350 mg hot elemene emulsion and tumor embolization by cisplantin-lipidol emulsion(cisplantin 60-80 mg+lipidol 8-15 ml)and glutin.Results Ten interventional procedures(TACE)were undertaken in 5 patients.Angiography showed that tumor blood supply mainly coming from collateral circulation adjacent to the tumors,but partially from hepatic artery.Tumor sizes decreased from 30% to 50% in 5 cases,and AFP declined in 4 cases after the treatment. Conclusion Pedunculated hepatocellular carcinoma possessing different blood supply features from intrahepatocellular carcinomas.But transarterial ehemoembolization is still an effective method of choice for this treatment.

Objective To investigate the relevant risk factors for fungal infection following operation of the gastrointestinal neo- plasm and offer supporting data for the prevention of fungal infection.Methods Medical records from 116 patients who under- went the operation of gastrointestinal neoplasm in the special group of this hospital from January 2006 to June 2006 were retro- spectively reviewed on the relevant risk factors by univariate and multivariate Logistic regression analysis.Results Of the 116 patients reviewed, 18 had fungal infection.Forty-six samples were positive for fungal pathogen.The most frequently isolated fungal strain was Candida albicans (15/20) and the most common infection site was gastrointestinal tract (14/18).Fungal in- fection after the operation of gastrointestinal neoplasm was significantly relevant with the duration of antibiotic use, duration of post-operative fasting, low serum albumin, high blood glucose and complication of bacterial infection.The duration of antibiotic use was a significantly independent risk factor.Conclusions Reasonable antibiotic use, nutritional support, early enteral nutri- tion and control of blood glucose should be taken into account after the operation of gastrointestinal neoplasm in order to prevent fungal infections.

OBJECTIVETo evaluate the effect of importing triamcinolone acetonide into hypertrophic scars with skin roller needles.

METHODSThirty-two cases with burn hypertrophic scar were treated. The skin roller needles were moved back and forth on the hypertrophic scars with triamcinolone acetonide dropping on the scar surface at the same time. So the triamcinolone acetonide could be imported into the scar through needles and needle holes. The effect was evaluated as cured, effective, and no effect. The Vancouver scaring criteria and visual analogue scale was used to assess the scar color, thickness, texture and feeling before and after treatment, as well as at the untreated scar area (control).

RESULTSThirty-two cases were treated 1-3 times, including 28 cases with cured result and 4 cases with effective result. The total effective rate was 100%. The scar color, thickness, texture and feeling was significantly different between the scar before and after treatment, or between the treated and untreated scar (P < 0.05).

CONCLUSIONSImporting triamcinolone acetonide into hypertrophic scars with skin roller needles is effective. It is a new method for the treatment of large hypertrophic scar with medicine.

Objective To explore the clinical effect of the transurethral ureteroscopic holmiumlaser lithotripsy in the treatment of ureteral calculi.Methods This study conducted a retrospective analysis of 205 patients with ureteral calculi from September 2015 to June 2017 in the affiliated hospital of Panzhihua university.According to the surgical method,all the patients were divided into control group (102 cases) who were treated with conventional pneumatic lithotripsy and observation group(103cases) who received transurethral ureteroscopic holmiumlaser lithotripsy.The surgical efficacy,renal function indexes and surgical indexes of the two groups were compared and analyzed respectively.Results The total effective rate of observation group was 97.06％,the control group was 85.00％,the difference between two groups was significantly(P ＜ 0.05).There was no significant difference in Cr and BUN level before surgery between two groups (P ＞ 0.05);after treatment,the Cr and BUN levels of two groups were improved significantly (P ＜ 0.05);while the renal function improved index of observation group was significantly better than that of control group,the difference was significant(P ＜ 0.05).The intraoperative blood loss,operative time and postoperative hospital stay of the observation group were significantly lower than those of control group (P ＜ 0.05).Conclusion The transurethral ureteroscopic holmiumlaser lithotripsy and normal air pressure ballistic were both well treatment for ureteral calculi,but patients with the holmium laser lithotripsy have better renal function indexes and operation index.

Objective To evaluate contrast-enhanced fluid-attenuated inversion recovery (FLAIR) imaging in the detection of leptomeningeal lesions.Methods Seventeen patients with a variety of leptomeningeal lesions were analyzed.The MRI protocol included un-enhanced and contrast-enhanced FLAIR images and contrast-enhanced T_1WI,Comparisons between contrast-enhanced FLAIR images and T_1WI and between un-enhanced and contrast-enhanced FLAIR images were made to determine which sequence better depicted the lesions.Results Leptomeningeal lesions showed as either diffusely or locally abnormal hyper-intensity along sulci or cistern on three sequences.Comparison between contrast-enhanced FLAIR and T_1WI showed that only contrast-enhanced FLAIR revealed the abnormalities in 7,both revealed the abnormalities but the former was superior in 2 ,and both were conspicuous in 7. In 1 patient of tuberculous meningitis,diffuse abnormalities of sulci were shown only on contrast-enhanced FLAIR, abnormalities of cisterns were shown on both sequences but the former was superior.Comparison between un- enhanced and contrast-enhanced FLAIR showed that only contrast-enhanced FLAIR revealed the abnormalities in 9,both revealed the abnormalities but the former was superior in 3,and both were conspicuous in 4. In 1 patient of tuberculous meningitis,abnormalities of cisterns were shown only on contrast-enhanced FLAIR,diffuseabnormalities of sulci were shown on both sequences but the former was superior.Conclusions Contrast-enhanced FLAIR images were superior to un-enhanced FLAIR images and contrast-enhanced T_1WI in the detection of leptomeningeal lesions. Contrast-enhanced FLAIR images are helpful and should be considered when findings on un-enhanced FLAIR images and/or contrast-enhanced T,WI are inconclusive.

Objective: To investigate the effects of pravastatin o n atherosclerotic plaque and cardiovascular events. Methods: Fifty- seven patients with coronary artery disease (44 male and 13 female, 58.4±11.3 y ears) were randommized into pravastatin and control groups. The patients in prav astatin group were administered 10 mg of pravastatin from the night of coronary angiography day. After 7.3 months (mean) of follow-up, plasma lipid parameters and coronary angiograph were repeated. Results: (1) A favorable effect on plasma lipid parameters was found. After administration, total choles terol(TC), low density lipoprotein cholesterol (LDL-C) and triglyceride(TG) red uced by 15.0% (P<0.01), 18.0% (P<0.01) and 6.0%, respectively. High den s ity lipoprotein cholesterol(HDL-C) increased by 10.6%. However, in control grou p, TC and LDL-C showed a tendency to reduce, but no significant difference was found between those of pre- and post-administration. (2)There was no significa nt difference in luminal diameter between pre- and post-administration in both groups. (3) Cardiovascular events in pravastatin group was significantly lower than those in control (P<0.05). (4) Pravastatin had no significant effect on HR, BP and left ventricular ejection fraction in both groups. Conclusio n: Pravastatin can stabilize coronary atherosclerostic plaque and reduce the incidence of cardiovascular events by improving plasma lipid parameters.

A randomized crossover study was performed to compare the effects of low glycemic index diets (LGI)and high glycemic index diets(HGI)on blood glucose,lipid profile and control of body weight in patients with type 2 diabetes.Compared with HGI group,the fasting serum insulin,Homa-IR,LDL-C and body weight significantly decreased in LGI group(P

BACKGROUNDDespite extensive research, the mechanism of immature dendritic cells (DCs) induced immune hyporesponsiveness remains incompletely understood.

METHODSRecipient DCs from C3H mouse bone marrow cells were incubated with donor antigen from splenic lymphocytes of C57BL/6 mouse; these DCs were transfected with CD80/86 specific siRNA using lentiviral vectors. Flow cytometry was used to evaluate expression of CD80/86 on the antigen-pulsed recipient DCs. Immune regulatory activity was examined by mixed lymphocyte reaction, in which irradiated DCs were cultured with C3H spleen T cells. After the reaction, interleukin (IL)-2, IL-4, IL-10, and interferon (INF)-γ levels of mixed lymphocyte reaction culture supernatant were measured by enzyme-linked immunosorbent assay. The apoptotic T lymphocytes were identified by Annexin V and CD3 staining.

RESULTSThere was a significant inhibition of CD80/86 expression in DCs transfected with CD80/86 lentiviral vectors compared with the control groups (P < 0.05), indicating the specificity of RNA interference. Enzyme-linked immunosorbent assay results showed a significant reduction of INF-γ, IL-2 and IL-10 in the CD80/86 lentivirus transfected group compared to the control groups (P < 0.05). There was no significant difference in IL-4 levels between the groups (P > 0.05). We also showed that CD80/86 low DCs loaded with alloantigen (1) stimulated low T cell proliferative responses via the indirect recognition pathway and (2) enhanced apoptotic activity (P < 0.05) in co-cultured T cells.

CONCLUSIONSLentiviral vector transfection can effectively and specifically knock down target genes in DCs. The CD80/86 low DCs may show tolerogenic activity via induction of T-cell apoptosis, thereby modulating the activity of recipient-derived DCs. The use of this approach may potentially be clinically applicable.

OBJECTIVETo investigate the regional spread of micrometastatic nodules in the mesorectum from low rectal cancer, and provide further pathological evidence to optimize radical resection procedure for rectal cancer.

METHODSA total of 62 patients with low rectal cancer underwent low anterior resection and total mesorectal excision (TME) was included in this study. Surgical specimens were sliced transversely and serial embedded blocks were made at 2.5 mm interval, and paraffin sections were stained with hematoxylin and eosin. The mesorectum on whole-mount sections was divided into three regions: outer region of mesorectum (ORM), middle region of mesorectum (MRM) and inner region of mesorectum (IRM). Microscopic spread were examined microscopically on the sections for the distribution in different mesorectal regions, frequency, types, involvement of lymphatic system and correlation with the primary tumor.

RESULTSMicroscopic spread of the tumor in mesorectum and ORM was observed in 38.7% (24/62) and 25.8% (16/62) of the patients, respectively. Circumferential resection margin (CRM) involved by microscopic tumor foci occurred in 6.5% (4/62) of the patients, and distal mesorectum (DMR) involvement was recorded in 6.5% (4/62) with a spread extent within 3 cm of distal border of the main lesions. Most (20/24) of the patients with microscopic spread in mesorectum were in TNM stage III.

CONCLUSIONResults of the present study support that complete excision of mesorectum without destruction of the ORM is essential for surgical management of low rectal cancer, and an optimal DMR clearance resection margin should not be less than 4 cm.
