Objective To observe the clinical effect of treating psoriasis vulgaris with Xianping Pills. Methods 120 patients of psoriasis vulgaris were randomly recruited into a experimental group (60 cases) and a control group (60 eases). The experimental group was treated with Diyin tablets (12 tablets per day) and the Xianping pill (18g per day) ; while the control group was treated with the Diyin Tablet (12 tablets per day) exclusively. Results The effective rate at the four weeks' treatment was 91.67% and 71.66% in the experimental group and the control group respectively, showing significant difference (χ~2=5,667, P<0.05). Conclusion The clinical effect of treating psoriasis vulgaris with Xianping Pills and Diyin Tablet is better than with Diyin Tablet only.

Objective To explore the current situation of knowledge,attitude and behavior of smoking among the college student.Methods 1855 subjects,who were randomly chosen from colleges,were investigated with the questionnaire and analyzed the recognition and behavior of smoking.Results 1700 valid questionnaire were reclaimed.(effective rate 91.6%).The awareness of harmful components in the cigarette,such as nicotine,Tar cigarettes,had no difference among different grades (P＞0.05),but the recognition about the nitrogen oxides,carbon monoxide and radioactivity in higher grades was higher than that of lowers(P＜0.01,).The rate of smoking was 21.1% in total,there was no significant difference among different grades (P＞0.05).Conclusion Although the level of awareness about the harmful components in the cigarette and its harmness to health was different among different grades.Health education should be enforced in college students.

Objective To explore the clinical characteristics of vagrant psychiatric patients with different gender and summarize nursing measures. Methods Toally 1165 vagrant psychiatric patients who all were inpatient in Shenzhen Corning Hospital between July 2014 to July 2015 were analyzed retrospectively. Seperately we analyzed incidence of nosocomial infection, aggressive behaviour, trouble-making level, restraint and protection, and activity daily living. Results There was 735 male (63.1%) and 430 (36.9%) female in 1165 vagrant psychiatric patients. Comparing with female patients, We found male patients had higher rate of nosocomial infection , aggressivity and accident level , who were susceptible to be restrained and protected ( P < 0 . 001 ) and needed more care (P<0.05). Conclusion We should specially take precautionary measures when nursing vagrant psychiatric patients with different gender.

BACKGROUND: The different level of proteins regulating cell cycle and theircorrelation is the main criteria to differentiate the benign and malignant cellular proliferation.OBJECTIVE: To investigate the expression status of p21waf1 and p53 in lung cancer as well as proliferating cell nuclear antigen (PCNA)DESIGN:A case-control study.SETTING: Department of Respiratory Medicine, Renmin Hospital ,Wuhan UniversityPAITICIPANTS:This case-control study involved 135 patients who underwent lobectomy or fiberoptic bronchoscopy for primary lung cancer or benign chronic pulmonary diseases at Renmin Hospital of Wuhan University from October 1996 through May 1999. They were divided into two groups: lung cancer group (76 patients, including 56 men and 20 women,aged 18-74 years of age) and chronic pulmonary diseases group (59 cases,including 42 men and 17 women, aged 16-70 years of age).METHODS: Phosphate buffer solution replaced the first antibody as the negative control. Immunohistochemistry was performed using a modified streptavidin-biotinylated peroxidase technique according to the manufacturer's recommendations (Maxim Corporation). For p21waf1 staining, we used hydrated autoclaving as a pretreatment. Antigen retrieval was performed in a standard microwave unit for p53 staining. PCNA staining did not need The ratio of the positive cells indicated by yellowish brown nucleus due to staining was counted for 5 successive high-fold microscopic fields: when it was≥ 10%, it was taken as positive; when it was ＜10%, it was regarded as high-fold microscopic fields for the percentage of the positive cells indicated by yellowish brown nucleus due to staining in each field, and the average value of the five fields was taken as labeling index (LI) for proliferated nuclear antigens.MAIN OUTCOME MEASURES: The expression leyels of p21waf1, p53and PCNA in lung cancer.cancer were 75% (57/76) and 47%(36/76) respectively. The labeling index of PCNA in lung cancer group was significantly higher than that of the chronic pulmonary diseases group (0.44±0.32 vs 0.09±0.14, respectively).significantly higher than that of small cell lung cancer (0.51 ±0.33 vs in lung cancer tissues. In chronic pulmonary diseases group, the expression of p21waf1 and p53 showed a close relationship with PCNA.CONCLUSION: It was found that p21waf1 and p53 were obviously upregulated in lung cancer and the degree of cellular proliferation in lung cancer was rather high. The capacity of DNA damage repair in squamous lung cancer may be stronger than that in small cell lung cancer.

Objective To evaluate the clinical value of elasticity imaging and area ratio by ultrasonography in differential diagnosis of benign and malignant thyroid nodules.Methods Gray-scale ultrasound and elasticity imaging was used to examine 88 patients with thyroid nodules.The elasticity classification and area ratio were retrospectively reviewed and compared with pathology.The elasticity grades 1 - 3 predicted benign,grades 4 - 5 predicted malignant.Results Eighty-eight patients with 116 thyroid nodules were detected,93 nodules were benign and 23 nodules were malignant.( 1 )An elasticity grades of 1 - 3 was observed in 82 (95.3％) of 86 benign nodules,while elasticity grades of 4 - 5 in 19 (63.3％) of 30 malignant nodules.The diagnosis sensitivity,specificity and accurate rate of the elasticity grades was 82.6％,88.2％,87.1％.(2) The mean of elasticity imaging and area ratio of 93 benign nodules (1.31 ± 0.13 ) was statistically lower than that in 23 malignant nodules ( 1.73 ± 0.13 ) (t =13.536,P =0.001 ).( 3 )According to ROC analysis,the cut-off point of elasticity imaging and area ratio was determined as 1.52.With elasticity imaging and area ratio ＜ 1.52,89 nodules [98.9％(89/90)] were confirmed as benign and 22 nodules [84.6％ (22/26)] were confirmed as malignant by pathology.The diagnosis sensitivity,specificity and accurate rate of elasticity imaging and area ratio was 95.7％,95.7％,95.7％.(4)The area under the ROC curve of elasticity imaging and area ratio ≥ 1.52 was 0.996,significantly higher than that of elasticity grades ≥ 4 (0.891).The diagnostic accurate rate of elasticity imaging and area ratio was significantly higher than that of elasticity grades(95.7％ vs.87.1％,x2 =5.472,P=0.019).Conclusions The elasticity imaging and area ratio by ultrasonography can be used in the differential diagnosis of thyroid lesions.It is a new diagnostic indicator for diagnosis of thyroid lesions.

Objective To investigate the risk distribution of breast cancer for location and time of recurrence metastasis in molecular subtype.Methods We studied retrospectively the female patients who were diagnosed as invasive ductal breast cancer in our hospital from July 2004 to June 2012,detected ER,PR,and HER2 expressions in the paraffin sections.The patients with recurrence metastasis were divided into local recurrence and distant metastasis with the first transfer site as standard for analyzing the distribution in molecular subtype and the time of the first site of recurrence metastasis.Results Sixty two patients were encountered recurrence metastasis,including 23 patients with local recurrence,and 39 patients with distant metastasis,death 11.The rates of distant metastasis for patients who belonged to HER2 type and basal-like type were higher than that of local recurrence (P =0.01,P =0.001).The risk distribution of recurrence metastasis time in molecular recurrence metastasis showed that 35 percent of recurrence metastasis time of luminal A type was first 3 years,75 percent of molecular subtype of basa1-1ike type recurrence metastasis time in first 3 years and advanced.The peak of luminal B and HER2 type was first 3 years,and very low in 5 years.Conclusions Molecular subtype of breast cancer is an important complement for TNM method in accurately assessing the patients of recurrence metastasis for location and time,and is helpful for the individual screening of patients for recurrence metastasis.

Objective To evaluate the effects and mechanism of valerian extract treatment on bleomycin-induced pulmonary fibrosis of rats. Methods After healthy Wistar rats(irrespective of sex)were given diethyl ether inhalation anesthesia, giving a single intratracheal instillation of bleomycin at a dose of 5 mg/kg to make a pattern of pulmonary fibrosis. 65 survival rats were randomly divided into four groups: Valerian high-dose groups(n = 16), Valerian low-dose groups(n = 16), Colchicine group(n = 16)and Model group (n = 17).Each group was given a dose of 100 mg/kg valeian extract everyday, a dose of 20 mg/kg valeian extract Valeian extract , a dose of 100μg/kg colchicine and a dose of 10ml/kg after second day. And in each groups, 6 rats were killed on day 7, 10 rats were killed on day 28 after instillation respectively. Rats in control group (n = 8) were instilled with saline intractracheally and saline was given everyday with a dose of 10ml/kg. Control group was killed on day 28. After rats were killed, The right lower pulmonary lobes were harvested for HE-staining, Masson-staining was used to observe the transformation of pulmonary tissue and immunohistochemistry was used to examine transforming growth factor-β1 (TGF-β1) which was analyzed by image analysis system. Results No obvious transformation were found in control group. The alveolitis in valerian and colchicine groups were ameliorated, compared with model group on day 7. The expressions of TGF-β1 in control group were lower than that in model group, and the mean integrated optical densities of TGF-β1 in control group were lower than that in mod-el group(P<0.05). The pulmonary fibrosis in valerian and colchicine group were ameliorated, compared with model group on day 28. The expressions of TGF-β1 in valerian and colchicine group were lower than that in model group. There were no significant differences between the valerian group and the colchicine group. Conclusion Valerian extract could reduce the degree of alveolitis and fibrosis induced by bleo-mycin through suppressing of TGF-β1.

Objective To investigate the relationship between gallbladder wall-typing and the main portal vein, right portal vein hemodynamics in patients with liver cirrhosis. Methods The main portal vein, right portal vein hemodynamics and the thickness of gallbladder wall were examined in 69 patients with cirrhosis and 30 normal subjects (control group) with two-dimensional ultrasound, color Doppler ultrasound and high-frequency ultrasound. According to the gallbladder wall-typing, 69 patients with liver cirrhosis were divided into not thickened, simple thickening and bilateral subgroups. The paremeters of hemodynamics and the thickness of gallbladder wall were compared among groups. Results There was statistical difference in thickness of gallbladder wall among all 3 subgroups. Statistical difference of the diameter of main portal vein (D_(pv)) was found among the subgroups (P<0.01), except between not thickened and simple thickening subgroup. Statistical difference of the velocity of the main portal vein (V_(pv)) was found between simple thickening subgroup and control group, as well as between bilateral subgroup and the control group (P<0.01). Statistical differences of quantity of blood flow in the main portal vein (Q_(pv)) were detected between bilateral subgroup and other 2 subgroups and control group (P<0.05). No statistical difference of diameter of right portal vein (D_(rpv)) and quantity of blood flow in the right portal vein (Q_(rpv)) was found among all groups and subgroups. The velocity of the right portal vein (V_(rpv)) of bilateral subgroup was statistically different with that of the control group and the simple thickening subgroup (P<0.05). No statistical difference of Q_(rpv)/Q_(pv) existed between the patients with liver cirrhosis and the normal subjects (P>0.05). There was positive correlation between the gallbladder wall thickness and D_(pv) (r=0.886, P<0.01). Conclusion The gallbladder wall-typing has no correlation with the right portal vein hemodynamics, but is related with the main portal vein hemodynamics. The bilateral and the thickness of gallbladder wall can indirectly reflect the hemodynamic changes of main portal vein. Obstruction to flow of cystic vein is not the main hemodynamic cause for the gallbladder wall changes in patients with liver cirrhosis and portal hypertension cause, indicating that there may be some intrinsic mechanisms of this phenomenon.
