Objective In this paper,we aimed at discussing the impacts of follow-up nursing on treatment compliance and lung function of patients with chronic obstructive pulmonary disease(COPD)during the rehabilitation period after discharge.Methods COPD patients(68 cases)were divided randomly into the intervention group and the control group with 34 cases in each group.We gave the intervention group follow-up nursins during the ensuing 6 months after discharge to give them guidance on health problems in order to promote the treatment compliance of patients.On the contrary,the control group did not take any follow-up nursing.Six months later,we conducted an evaluation of the tmalment compliance and amelioration of lung function in the t wo groups.Results As a result,six months after discharge,the patients'treatment compliance status and lung-function indicators in the intervention group were significantly better than those of the control group(P＜0.01).Conclusions The follow-up nursingcan promote the COPD patients'treatment compliance status and amelioration of lung function during the rehabilitation period.

Objective To investigate the effects of minocycline,a selective microglia inhibitor on dorsal GABAB receptor expression in the spinal cord in a rat model of neuropathic pain and the possible mechanism.Methods Forty-eight male SD rats weighing 220-260 g were used in this study.Neuropathic pain was induced by ligation of L5 spinal nerve(SNL).The animals were randomly divided into 4 groups(n=12 each):Ⅰ sham operation;Ⅱ SNL;Ⅲ sham operation+intrathecal(IT)minocycline 50 μg;IV SNL+IT minecycline 50 μg.Paw withdrawal threshold to von Frey hair stimulation was measured before operation(baseline)and at post-surgery days 1,2,4,6,8,10,12,14,16,18 in 6 animals in each group.The GABABR2 expression in dorsal horn of spinal cord was detected by Western blot at the time point when paw withdrawal threshold to mechanical stimulation was the lowest in another six animals which did not undergo yon Frey hair stimulation test.Results The paw withdrawal threshold to mechanical stimuli and the GABABR2 expression in the dorsal horn of spinal cord were significantly lower in SNL group than in sham operation group.The decreased paw withdrawal threshold to von Frey hair stimulation and the down-regulated GABABR2 expression in the spinal cord induced by SNL were ameliorated by intrathecal administration of micmglia inhibitor- minocycline in group Ⅳ.Conclusion The mechanism of neuropathic pain mediated by microglia activation may be related to the inhibition of GABAB receptor activation.

Objective To observe the effect of moxibustion on the blood lipid and hemorheology in senile patients with coronary heart disease (CHD) due to heart blood stagnation who underwent interventional treatment.Method A hundred senile CHD patients were randomized into a treatment group and a control group, 50 cases in each group. The control group was intervened by conventional medications, while the treatment group was additionally by thunder-fire moxibustion. The blood lipid and hemorheology were observed before the treatment and after 3 treatment courses.Result The blood lipid parameters (including CHO, TG, HDL-C and LDL-C) were changed significantly in the treatment group after the intervention (P<0.05). The CHO, TG, and LDL-C levels of the treatment group were significantly different from that of the control group (P<0.05). The hemorheology parameters (whole blood viscosities at a high-, middle-, and low-shear rate, and fibrinogen) were significantly changed in the treatment group after the intervention (P<0.05). The whole blood viscosities at a high-, middle-, and low-shear of the treatment group were markedly different from that of the control group (P<0.05).Conclusion Thunder-fire moxibustion can down-regulate the blood lipid and blood viscosity of CHD patients undergone interventional treatment, and thus improve myocardial ischemia.

In order to set up a base for stem cells to be widely used in clinical medicine, we tried to optimize, in this study, the technique that induces human mesenchymal stem cells (hMSCs) to differentiate into neural stem cells by using cerebrospinal fluid (CSF) from the different groups. After the induction, presence of neural stem cells was confirmed with microscope observation, flow cytometry analysis, immunohistochemistry and fluorescent immunohistochemistry. At the same time, we also compared and analysed the data of the number of stem cells when it totally met the requirements for clinical treatment and the days required. At last, we confirmed that hMSCs could be induced to differentiate into neural stem cells, and that the number of cells totally met the requirements for clinical treatment. But there were some differences both in the number of cells and the days required. Among the groups, the group that marrow mesenchymal stem cells from patients own induced by CSF from healthy volunteers used the shortest time and the quantity of the cells was significantly higher than those of the others.

A 48-year-old man presented with a 4-day history of fever and 10-year history of papulovesicles on the face, neck, trunk and limbs which had been aggravated 10 days prior to the presentation.Skin biopsy showed a dermal infiltration of numerous small- to medium-sized atypical lymphocytes, which was mainly located around blood vessels or appendages, with the involvement of subcutaneous fat tissue and destruction of blood vessels. The infiltrating atypical cells stained positive for CD45RO, CD8, CD56, T-cell intracellular antigen-1, granzyme B, Epstein-Barr virus-encoded small nuclear RNAs (EBER), but negative for CD20, CD79a, CD3, CD4 or CD30. Cytoplasmic CD3ε was also observed in these cells. Laboratory examinations on admission revealed a progressive decrease in peripheral erythrocytes, white cells and platelets, persistent increase in serum aminotransferase and bilirubin, and decline in serum fibrinogen and hypertriglyceridemia. The B-mode ultrasound of the abdomen showed hepatosplenomegaly. Based on the above findings,the diagnosis was made as extranodal nasal type NK/T-cell lymphoma of skin complicated by hemophagocytic syndrome.

Objective To investigate the minimal persistent pigment dose (MPPD)of normal skin to UVA in Guangzhou city,and to observe its relationship to sex,age,skin type,seasons,ITA,and the years lived in Guangzhou.Methods 316 healthy subjects were exposed to Solar 601-300,and the MPPD was measured and observed by two professional technicians after 2-3 hours.Results The average MPPD value of all subjects was (9.61±2.57) J/cm2.In male and female,the average MPPD values were (11.09 ± 2.82) J/cm2 and (9.01 ± 2.20) J/cm2 respectively,and male was significantly higher than female (P＜0.01).There was significant difference of the MPPD value in different seasons (P＜0.01).The MPPD value in winter (10.66± 2.71) J/cm2) was significantly higher than spring (9.37±2.39) J/cm2,summer (9.53±2.66) J/cm2 and autumn (8.98±2.25) J/cm2.There was significant difference of the MPPD value between different ITA groups (P＜0.01).ITA grade-3 (10.72± 2.84) J/cm2 was significantly higher than grade-1 (8.50±1.45) J/cm2 and grade-2 (9.12±2.31) J/cm2 (P＜0.01),but there was no significant difference from grade-4 (11.87±2.73) J/cm2 (P =0.93).The MPPD value in subjects lived in Guangzhou over 10 years (8.97± 1.88) J/cm2 was significantly lower than those whose residence was less than 1 year and from 1 to 5 years,respectively (P＜0.01),but there was no significant difference from those lived from 5 to 10 years (P =0.47).Conclusions The MPPD value of the subjects in Guangzhou is related to gender,seasons,ITA grade and the years lived in Guangzhou city,while there is no correlation with age and skin types.

Objective Compare the complications between laparoscopic and abdominal cervical cancer surgery, and investigate the safety of laparoscopic cervical cancer surgery and complications classified by Clavien-Dindo classification, then analyze the risk factors. Method Clinical data of 215 cases of cervical cancer received surgery from March 2011 to October 2014 was collected, which include intraoperative, postoperative and postoperative fol﹣low-up data. All the cases were divided into two groups: LRH group (n= 116) and ARH group (n= 88), then ana﹣lyze and compare the difference of intraoperative, postoperative complications and postoperative follow-up data be﹣tween the two groups, assess the safety of the two groups, and statistically concluded related independent risk factors. Results The complications of 204 patients were classified into 4 grades. The criticality and morbidity of intraopera﹣tive and postoperative complications have no significant difference between the two groups (P> 0.05). Logistic re﹣gression analysis show that over criticality grade Ⅱ of LRH intraoperative complication related to operating time, over criticality grade Ⅱ of ARH intraoperative complication related to aged over 50 yr, over criticality grade Ⅱ of ARH intraoperative complication related to BMI> 25. Conclusions Through the analysis of laparoscopic operation and the criticality of complications, the safety of the two groups were no difference. The patients with high risk fac﹣tors should be evaluated comprehensively. And strictly grasp the contraindication and indication.

Objective To study the effect of pinealctomy and melatonin on the cell cycle distribution during T cell development in thymus. Methods SD rats were divided into 5 groups:normal controls,sham-operated controls,pinealectomy,pinealectomy+melatonin injection 7.5 mg/kg; and pinealectomy+melatonin injection 15 mg/kg.The animals were sacrificed at 4 or 8 weeks after operation.cycilnA +and cyclinE +T cells in thymus were dyed with immunocytochemical ABC methods, measured by computer image analysis.Cell cycle analysis was performed by flow cytometry.The expression of cyclin-dependent kinase inhibitor 1? was tested by RT-PCR method. Results The effect of pinealectomy on the expression of cyclinE was stronger than that of cycilnA. Pinealectomy promotes the synthesis of cyclinE in thymus.The percentage of G-0/G-1 phase cells was decreased and G-2/M phase cells was increased.These would be convalescente by supplement with melatonin,but the reaction to melatonin was differencet in thymus cortex and in medulla.Melatonin enhanced the expression of cyclin-dependent kinase inhibitor 1? in thymus.Conclusion Pinealectomy influences notably the T cells development in thymus.Rejuvenation of degenerative thymus could be observed by melatonin administration.

Objective To evaluate the diagnostic value of invasive cardiac catheterization for restrictive cardiomyopathy (RCM) and constrictive pericarditis (CP).Methods Twenty-seven children with CP or RCM hospitalized in Department of Cardiology,Shanghai Children's Medical Center,School of Medicine,Shanghai Jiaotong University from February 2002 to December 2015,were selected,including 10 patients who had been surgically documented CP and 17 patients with RCM who underwent cardiac catheterization.Intracardiac pressure waveforms were recorded and all the measurement indexes of pressure of all the patients were analyzed.The changes of cardiac pressure under deep breathing in 9 patients with local anesthesia was recorded.Results There were significant differences in pulmonary artery pressure,difference between left ventricular end-diastolic pressure (LVEDP) and right ventricular end-diastolic pressure (RVEDP),and the ratio of RVEDP/right ventricular systolic pressure between group RCM and group CP [(50.2 ± 12.0) mmHg(1 mmHg =0.133 kPa) vs.(38.1 ±6.8) mmHg,(7.8±5.5) mmHgvs.(1.8 ±4.7) mmHg,0.27 ±0.10vs.0.45 ± 0.20,respectively;t =2.912,2.787,2.418,all P ＜ 0.05].However,there was overlapping for these criteria,and the predictive sensitivity of any of the criteria was less than 66.7％.In patients with CP,reciprocal changes in the filling between right ventricle and left ventricle occurred during respiration.In patients with RCM,the right ventricle and left ventricle pressures moved concordantly with respiration.The systolic area index was greater in group CP than that in group RCM (1.20 ± 0.03 vs.0.70 ± 0.14),and the difference was significant (t =6.152,P ＜ 0.01).The systolic area index had a sensitivity of 100.0％ and a predictive accuracy of 100.0％ for the identification of patients with surgically proven CP.Conclusions Measurements in catheterization,especially the ratio of right ventricular to left ventricular systolic area during inspiration and expiration is a reliable catheterization criterion for differentiating CP from RCM.
