Objective To explore the safety and effectiveness of transurethral resection of the prostate (TURP) for large benign prostatic hyperplasia.Methods A total of 56 cases of patients with large benign prostatic hyperplasia were analyzed retrospectively.Results The weight of prostate tissue resected with TURP was 60.2 g (48-122 g).The resection rate was 60％,operation time 113.4 min (70-180 min).The lower urinary tract symptoms (LUTS) after TURP was improved significantly.The international prostate symptom scores (IPSS) of 38 cases were decreased from (25.6±1.5) before operation to (6.0± 2.0) after operation.The maximum urine flow rate were increased from (5.0±1.9) ml/s to (18.0±4.5) ml/s.The mean residual urine volume of 22 cases were reduced from 95 ml (40-250 ml) to 10 ml (0-60 ml).Conclusions Skilled TURP technology for large benign prostatic hyperplasia is a safe treatment with good effect and low complications rates.

Objective To investigate the therapeutic effect of medication-based acupuncture on osteoporotic compression fracture and explore clinical effective intervention in the patients. Method Fifty-six patients were randomized to acupuncture-medicine and medicine groups, 28 cases each. The clinical therapeutic effects were evaluated after treatment. Bone density, BGP and IL-6 were measured before and after treatment. Result BGP and IL-6 decreased significantly in the two groups after treatment compared with before (P<0.01) and decreased more in the acupuncture-medicine group than in the medicine group (P<0.05). BMD increased significantly in the acupuncture-medicine group after treatment compared with before (P<0.05) and did not increased significantly in the medicine group after treatment (P>0.05). Conclusion Warm needling moxibustion plus medication is effective than medication alone in treating osteoporotic compression fracture. It can decrease serum BGP and IL-6 contents and relieve the clinical symptoms in the patients. Acupuncture plus medicine not only produces a marked analgesic effect but also has a positive role in preventing the aggravation of osteoporosis and avoiding second fracture.

Objective To evaluate the technique of finger palpation in thoracoscopic localization in patients with pulmonary nodules,and to summarize its technical details,especially with exploit of chest computed tomography (CT) facilitating it.Methods 95 patients with total amount of 109 pulmonary nodes 20 mm or smaller in size shown with lung window of CT,were reviewed.They were located subpleurally,with a median depth of 8.2 mm and a median size of 10.0 mm.The value of their depth over their size (D/d value) could be used as the extent of localizing difficulty.Each node had its own radiographic fealures for being localized,which was built preoperatively.Under thoracoscopic vision,nodules were finger-palpated by index finger via the 4th or 5th intercostal space on anterior axillary line,followed by wedgectomy or lobectomy for instant histopathological diagnosis to further decide the final surgical type.The distance between the nodule and the origin of segmental bronchus (L value) were also calculated out,as it might be relevant to the way the nodule could be biopsied.Results All nodules were successfully localized and resected for biopsy goal,105 by wedgectomy,4 by lobectomy.After intraoperative diagnosis was made by the pathologist,VATS lobectomy and lymph node dissection were further performed in 55 patients.L value of 4 cases being biopsied by lobectomy ranged from 18.3 to 30.3 mm,averaging 26.1 mm.Conclusion Finger palpation is viable in any cases of pulmonary nodules.Detailed reference of CT digital information,and enough detachment of mediastinal pleura,can greatly facilitate thoracoscopic localization by finger palpation.Lobectomy or segementectomy is preferable when L value is less than 30 mm.

Objective To evaluate the expression of Toll-like receptor(TLR)on the monocyte- derived dendritic cells(DC)from chronic hepatitis B(CHB)patients and to analyze the expression pro- file and significance of the TLR such as TLR3,TLR4,TLR?,TLR8 and TLRg,which are associat- ed with immune response to viral infection.Methods Peripheral blood mononuclear cell(PBMC) centrifugated by the hydroxyethyl starch(HES)centrifugation were cultured and induced into DC by granulocyte-maerophage colony stimulating factor(GM-CSF)and interleukin-4(IL-4),and their mor- phology and phenotype were detected by the inverted microscope and flow cytometry respectively. Monocyte-derived DC were obtained from 10 chronically hepatitis B virus(HBV)-infected patients and 15 healthy volunteers.TLR3,TLR4,TLR7,TLRS,TLR9 expression on immature and mature DC were analyzed by FACS Calibur.DC was pulsed with HBcAg on day 3 and 5,then DC maturation and ability to process HBcAg and to stimulate autogeneic T cells were evaluated.Results Monocyte- derived DC developed different TLR expression patterns as they went through different maturation stages.TLR7,TLR8 expressions on immature DC and TLR3,TLR7 expressions on mature DC were lower in CHB than in control(for TLR7,TLR8 expression on immature DC:75.9%,1.0%vs 98.4%,15.4%,P

Objective To observe the effects of vitamin C (VC) and E (VE) on the uhrastrueture of liver, kidney and brain tissue of fluorosis rats. Methods One hundred and twenty Wistar rats were chosen as the experimental animals and were divided into 9 groups randomly. The control group were given distilled water and the fluoride exposed group were given distilled water containing sodium fluoride 150 mg/L. The throe VC-fluoride exposed groups were given VC orally in a dose of 50,100,150 mg·kg-1.d-1, respectively, and the three VE-fluoride exposed groups were given VE of 25,50,75 mg·kg-1·d-1, respectively. The VC-VE-fluoride exposed group were given VC of 100 mg·kg-1·d-1and VE of 50 mg·kg-1·d-1at the same time of high fluoride water intake. The rats were sacrificed after 9 months and the ultrastructure changes on liver, kidney and brain tissues of each group were observed under transmission electron microscope(TEM). Results The uhrastrueture of liver, kidney and brain showed pathologic changes in the rats that drank water containing high eoneentrations of sodium fluoride. ①Edema of hepatocytes, smeared mitochontria and nuclear matrix, lipid droplet in eytoplasm of hepatocytes, margination of nueleohs as well as obvious swelling of liver sinusoidal endothelial were observed in fluoride exposed group. ② There were marginafion of heterochromatin, expansion of cell space and endoplasmic reticulum in the kidney after the exposure to excess fluoride.③Signifieant changes were found on glial eells on the brain, including cell swelling, increase and marginafion of heterochromatin in the fluoride exposure group. There were no significant uhrastrueture changes in the VC or VE intervention group, while the VC-VE-fluoride exposure group was almost the same as the control group. Conclusions Fluoresis may cause damage on liver, kidney and brain in rats. VC and VE, alone or combined, have protective effects, and the combined supplementation was stronger than single supplementations.

Objective To investigate the effect of human cytomegalovirus (HCMV) on proliferation of colony forming unit T-lymphocyte (CFU -TL)and its interference methods. Methods Normal CFU - TL culture was used as blank control. Normal CFU- TL culture system plus inactivated HCMV fluid as inactivated HCMV control. The dilution of 1:10,1:100,1:1000 were added into CFU -TL colonies culture system directly as infected group. Astragalus (AMI) and ganciclovir(GCV) were added into culture system with HCMV dilution of 1:10 as experimental group. By methylcellulose semi-solid culture, different concentrations of HCMV - AD1699 affect CFU-TL and interfered by astragalus AMI, GCV. CFU - TL were surveyed. The effect of HCMV on CFU-TL proliferation was measured by MTT; HCMV-AD169 DNA in CFU-TL was found by PCR. Results 1. Compared with control group, the numbers of CFU -TL in the HCMV infection groups decreased significantly(P

Objective: To study difference of the immune response between oral administration and intraperitoneal injection of total polysaccharide of Sijunzi decoction (SJTP) in mice. Methods: The immunosuppressed mice model was established by intraperitoneal injection of cyclophosphamide (CY). The effects of SJTP on the weight of immune organs,hemolysin response and delayed type hypersensitivity (DTH) were observed,and the influences on normal mouse spleen lymphocytic proliferation of mice were also studied. Results:SJTP can remarkably counteract the immunosuppression induced by CY, decrease the weight loss immune organs,increase the hemolysin response and DTH,and promote the proliferation of lymphocytes.The effect of oral administration is superior to intrapertoneal injection.Conclusion:SJTP can improve the humoral and cellalar immunity of mice.The immune activities resulting from oral administration of SJTP have some special characteristics,and its possible mechanism is also discussed.

To investigate the effect of Tanreqing injection on immune activity of peripheral blood lymphocytes of patients with lung cancer. The peripheral blood lymphocytes of patients with lung cancer and healthy persons were separated by the density gradient centrifugation method for subsequent experiments, with those from healthy persons as the positive control. The effect of Tanreqing injection on stimulating the proliferation of lymphocytes with phytohemagglutinin (PHA) was determined by MTT method. The effect of Tanreqing injection on the lymphocyte secretions of IFN-γ and TNF-α and the subset ratio of lymphocytes cultured separately or with Tanreqing injection of different concentrations were examined by ELISA and flow cytometry (FCM) respectively. In addition, the LDH release assay was used to detect the cytotoxicity of cytotoxic T cells (CTL) and natural killer cells (NK). According to the findings, all of immunological indexes of lymphocytes from patients with lung cancer were weaker than that of healthy persons, but with the obvious increases in proliferation activity and IFN-γ and TNF-α secretions of lymphocytes co-cultured with Tanreqing Injection (P < 0.05). Among lymphocyte subsets co-cultured with Tanreqing Injection, CD3+, CD3+ CD4+ and CD3- CD16 + 56+ cell ratios notably increased, whereas CD4+ CD25+ Treg cell ratio obviously decreased (P < 0.05). In the meantime, Tanreqing injection can markedly promote the cytotoxicities of CTL and NK (P < 0.05). In conclusion, Tanreqing injection shows a significant effect in promoting the immune activity of lymphocytes from patients with lung cancer and their anti-tumor immunity.
