ObjectiveTo observe the clinical efficacy of acyclovir in treatment of children with herpes angina. Methods127 patients suffered from herpes angina were randomly divided into two groups of children,the treatment group,64 patients received the symptomatic treatment on the basis of such general use of acyclovir treatment. The control group 63 cases, received the same general treatment as treatment grounp and, intravenous ribavirin. clinical effect was observed. ResultsThe effective rate was 98.44％, of which 37 cases markedly effective in 26 cases, 1 case of invalid; the control group, the total effective rate was 82.54％, Narkedly effective in 24 cases, effective in 28cases,ineffective in 11 cases. Two groups had significant difference. ConclusionAcyclovir in treatment of children with herpes angina could rapidly control the disease,and the clinical recovery time and efficacy was better than ribavirin.

Objective:To investigate the marginal microleakage after cavity preparation by Er:YAG la-ser and conventional bur applying different adhesive systems , conditioning surface with acid etching or not.Methods:In the study, 50 primary teeth were divided into 5 groups.(1) Bur+etch-and-rinse sys-tem, (2) Bur+self-etching system, (3) Er:YAG laser+etch-and-rinse system, (4) Er:YAG laser+self-etching system, (5) Er:YAG laser+none-etched.The class V cavities were all filled with composite resin.The microleakage tests were performed , observed and scored under stereomicroscope .Results:Bur+etch-and-rinse group had higher microleakage than Er:YAG laser +etch-and-rinse group , and Bur+self-etching group had higher microleakage than Er:YAG laser +self-etching group ( P<0 .05 ) . There was no difference between Er:YAG laser+etch-and-rinse group and Er:YAG laser+self-etching group, while they had significantly lower microleakage than that of Er:YAG+none-etched group.Con-clusion:Composite resin restoration showed less marginal microleakage when all-in-one self-etch system was used after irradiation by Er:YAG laser on primary teeth .

Objective To explore the effect and mechanism of atorvastatin on pulmonary hyper-tension in chronic pulmonary heart disease.Methods Sixty eight patients with chronic pulmonary heart disease were randomly divided into treatment group (n=35) and observation group ( n=33 ).Thirty healthy people were picked up from people taking physical examination at the same stage as control group.Patients in both treatment and observation groups were given routine treatment and the observation group were given atorvastatin (20 mg/d) supplement.Changes in pulmonary function,ultrasound cardiogram,plasma high-sensitive C-reactive protein (hs-CRP) and interleukin (IL-8) were observed before and after 6 months of treatment.Results The levels of hs-CRP,IL-8 and pulmonary arterial pressure in treatment and observation groups are higher than that in normal group before treatment (t=2.87,2.79,3.01,3.28,3.31,3.15,respectively,and P =0.005,0.007,0.004,0.001,0.001,0.002,respectively).The pulmonary arterial pressure,hs-CRP,IL-8 in observation group after treated for 6 months were significantly lower than those before treatment and in treatment group (t=2.17,2.59,2.63,1.91,1.86,1.74,respectively,and P =0.039,0.008,0.007,0.031,0.037,0.042,respectively).The pulmonary function indexes including FEV1 and FEV1/FVC in observation group were much better than those in treatment group after 6 months treatment (t=1.84,2.13,respectively,and =0.037,0.024,respectively).There were no significant differences on these indicators in treatment group after 6 months treatment when compared with before treatment ( P ＞ 0.05 ).Conclusion Atorvastatin can effectively improve the life quality and pulmonary function,decrease pulmonary arterial pressure of patients with chronic pulmonary heart disease.These effects may be related to the inhibition of inflammation in pulmonary vessels.

Objective To explore the development trends in community nursing. Methods The current situation of community nursing in Shanghai was analyzed by means of questionnaire surveys and literature review. Subjects A total of 3 173 questionnaires were distributed to community nurses, hospital nurses, community residents, and hospitalized patients and 2 942 of them were retrieved, the rate of retrieval being 93.8%. Results The demand for community nursing was not satisfied, the number of community nurses was insufficient and their general quality was low. Conclusion The scope of services in community nursing needs to be expanded with demand as a guide, more community nurses need to be cultivated, and the quality of the nursing contingent needs to be enhanced.

Objective To investigate the factors affecting rural women suffering from postpartum depression in order to provide scientific basis for rational intervention.Methods 368 rural pierperas whose deliveries were in the First Affiliated Hospital of Shanxi Medical University were surveyed by trained professional nurses with the Edinburgh Postnatal Depression Scale from May 1,2013 to April 30,2014.The data were processed by chi square test and unconditional logistic regression analysis to find the independent risk factors associated with postpartum depression.Results There were 347 valid questionnaires.The incidence of depression after delivery was 25.1％ (87/347).Logistic regression analysis showed that the low income family [OR=1.982 (1.238-2.562)],the inconformity of actual and expected baby gender [OR=0.465 (0.183-0.759)] and the mother-in-law as caregiver of pierpera [OR=2.459 (1.950-2.913)] were independent risk factors for postpartum depression of rural women,three of them are significant statistically,P＜0.05.Conclusions Understanding the risk factors for postpartum depression and being targeted to guide individually can reduce the incidence of postpartum depression.

It is important to establish a simple method of culture in vitro to obtain purity oligodendrocyte. This paper introduced the re-searches about co-culture in vitro with rat cortical gliocyte, proliferation and differentiation of oligodendrocyte progenitor, differentiation of oligodendrocyte and identification of cell surface antigens at different stages of development.

Objective To explore the factors affecting the prognosis for a child in a persistent vegetative state (PVS).Methods Forty-three PVS children were selected and provided with comprehensive rehabilitation training.It included physical therapy such as Rood approach and range of joint movement training,medication and hydro-acupuncture at the head points.After three months,each patient's state of consciousness was quantified,and multiple-factor unconditional logistic regression was conducted to identify factors relating to any changes.Results By the end of the intervention,29 of the patients had regained consciousness,a recovery rate of 67％.Logistic regression revealed that age,brainstem auditory evoked potentials (BAEP) and PVS score at admission all were closely related with whether a child regained consciousness.Gender,type of damage,EEG score,and the initial time of intervention had no significant relationship with regaining consciousness.Conclusions Older PVS patients with higher BAEPs and PVS scores at admission are more likely to regain consciousness.

Objective To evaluate spectral CT imaging in characterizing the pathological type and the differentiation of gastric cancer.Methods Ninety-one patients diagnosed of gastric cancer were retrospectively analyzed.Patients were all underwent triple-phase enhanced scan using single source dualenergy CT on gemstone spectral imaging(GSI) mode.Three types of images were reconstructed for analysis:the water concentration (WC),iodine concentration (IC),and normalized iodine concentration (NIC).The patients were divided into groups of mucinous carcinoma (MUC),including mucinous adenocarcinoma and signet ring cell carcinoma,and non-mucinous gastric carcinoma (non-MUC).Independent-samples t test was used for statistical analysis.Results There were 24 patients of MUC and 67 patients of non-MUC.The IC and NIC of the non-MUC were significantly higher than the MUC in vein phase (VP) and in parenchymal phase (PP) [(21.33 ±6.31) × 100 vs (16.94 ±6.13) × 100 μg/ml,0.55 ±0.17 vs 0.42 ±0.14 in VP,and(20.65 ±5.49) × 100 vs (18.07 ±4.51) × 100 μg/ml,0.72 ±0.20 vs 0.57 ±0.12 in PP,respectively t =-2.948,-3.362,-2.261,-4.326,P ＜0.05].The IC and NIC of the signet ring cell carcinoma were statistically higher than those of the mucinous adenocarcinoma [(19.36 ± 4.75) × 100 vs (12.10 ±5.92) ×100μg/ml,0.49 ± 0.09 vs0.28±0.11 in VP,and (19.88±3.28) ×100 vs (14.45±4.62) ×100 μg/ml,0.63 ±0.08 vs 0.47 ±0.11 in PP,respectively t =3.253,5.180,3.339,3.850,P ＜0.01].For the poorly differentiated and well /moderately differentiated adenocarcinoma,the IC and NIC of the former were higher than those of the latter in VP and PP [(23.48 ±6.49) × 100 vs (18.98 ±5.26) × 100 μg/ml,0.61±0.16vs0.48±0.15 in VP,and (22.95±5.51) ×100 vs (18.28±4.47) ×100 μg/ml,0.81 ± 0.21 vs 0.63 ± 0.15 in PP,respectively t =3.098,3.249,3.766,4.117,P ＜ 0.01].The between-group differences of WC,IC and NIC in artery phase were no significant (P ＞ 0.05).Conclusions Different pathological types could determine different IC.The spectral CT imaging may be helpful for characterizing the pathological type of gastric cancer.

Objective To evaluate the effects of 131I treatment for Graves hyperthyroidism patients with leucopenia and the alteration of WBC levels after treatment.Methods A total of 257 Graves hyperthyroidism cases were retrospectively studied after 131I treatment.Based on baseline WBC count,119 cases with WBC count ＜4.0 × 109/L before 131I treatment were diagnosed with leucopenia and 138 cases had normal WBC.There were no significant differences in age,weight of thyroid,131I uptake rate in 24 h,dose of 131I and course of the disease between the two groups (all t ＜ 0.972,all P ＞ 0.05).WBC,lymphocyte,neutrophil and platelet counts were recorded before and 1,3,6 and 12 months after 131I therapy.The therapeutic effects were graded as clinical cure,improvement,invalidation and hypothyroidism.Statistical analyses,including independent samples t test,x2 test and one-way analysis of variance,were performed using SPSS 13.0.Results The WBC levels in the leucopenia group were (3.49 ± 0.43) × 109/L,(4.06 ±0.98) × 109/L,(4.20 ±1.04) × 109/L,(4.37 ±0.93) × 109/L and (4.88 ± 1.20) × 109/L before 131I treatment and 1,3,6,12 months after 131I treatment,respectively; while,those in the normal WBC group were (5.70 ± 1.08) × 109/L,(5.50 ± 1.14) × 109/L,(5.74 ±0.99) × 109/L,(5.95 ± 1.14) × 109/L and (6.07 ± 1.17) × 109/L,respectively.There was no statistically significant difference of WBC levels before and 1 month after 131 I treatment (t =1.662,P ＞ 0.05) in the normal WBC group,but WBC levels at those timepoints were significantly different in the leucopenia group (t =3.816,P ＜ 0.05).In the leucopenia group,there was no significant change of lymphocytes before and after 131I treatment,while the average neutrophil count showed an increasing trend during the 1,3,6 and 12 months after 131I treatment (F =40.583,t:1.468-11.264,all P ＜ 0.05).The average platelet counts at 6 and 12 months after 131I treatment were (187.80 ± 36.03) × 109/L and (206.88 ± 26.04) × 109/L respectively,which were higher than that before 131I treatment (F =9.735,t =2.604,4.892,all P ＜0.05).In the normal WBC group,there were no statistical differences of WBC changes before and after 131I treatment except for a lower lymphocyte count at 1 month after 131I treatment than that at baseline ((1.79 ± 0.37) × 109/L vs (1.99 ±0.63) × 109/L;F =12.868,t =3.284,both P ＜ 0.05).The treatment effects of the two groups were not significantly different (x2 =0.739,P ＞ 0.05).Conclusions 131I treatment presents similar therapeutic effects on Graves hyperthyroidism patients with leucopenia and those with normal WBC levels.WBC levels in patients with leucopenia may recover to baseline during the post-treatment follow-up.Thus 131I treatment is a safe and effective method for Graves hyperthyroidism patients with leucopenia.
