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.

Objective To investigate the minimal erythema does (MED) of normal skin to UV in Guangzhou city,and to observe its relationship to sex,age,skin type,seasons and the years lived in Guangzhou.Methods 621 healthy subjects were exposed to Solar Simulator (GS2004) and the MED was measured and observed by two professional technicians after (24±2) hours.Results The average MED value of all subjects was (1170.2±333.2) mJ/cm2.In male and female group,the average MED values were (1132.8-339.4) mJ/cm2 and (1182.1 ± 330.7) mJ/cm2,respectively,and there was no significant difference between male and female (P=0.20).The MED value in subjects aged from 30 to 50 (1014.7 ± 359.7) mJ/cm2 was significantly lower than those aged from 20 to 29 (1222.9±304.3) mJ/cm2 and over 50 years (1179.0±374.3) mJ/cm2 (P＜0.01).The MED value in skin type Ⅱ (673.53±228.3) mJ/cm2 was significantly lower than those in type Ⅲ (1224.3±254.2) mJ/cm2 and Ⅳ(1363.1±278.5) mJ/cm2(P＜0.01).There was significant difference of the MED value between different seasons (P＜0.01).The MED value in spring (969.2±355.8) mJ/cm2 was lowest,and followed by summer (969.2± 355.8) mJ/cm2.However,there was no significant difference between autumn and winter (P＞0.05).The MED value in subjects lived in Guangzhou from 5 to 10 years was significantly lower than those whose residence time was from 1 to 4 years and over 10 years,respectively.Conclusions The MED value of the subjects in Guangzhou is quite different from other cities of China,and related to age,skin types,seasons and the years lived in Guangzhou city,while there is no correlation between MED value and gender difference.

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 analyze the clinicopathologic features of mucinous cervical adenocarcinoma (ADC) and supply some reference for its diagnosis,treatment and prognosis.Methods Totally 88 cases with primary mucinous ADC diagnosed between January 2003 and December 2007 in Jiangxi Maternal and Child Health Hospital were retrieved.Their clinical and pathological data were reviewed and analyzed.Results Among 88 patients,70 cases of them were endocervical ADC,11 cases were minimal deviation adenocarcinoma (MDA),2 cases were intestinal subtype and 5 cases were villoglandular ADC.The positive rate of cervical Pap smear cytology was only 28％ (10/36).There were 10 cases were performed several times of cervical Pap smear cytology test and biopsies,while still no abnormality was found.Finally,7 cases of them were diagnosed by cervical excisional biopsy and endocervical curettage,including 5 cases with endocervical ADC and 2 cases with MDA; 2 cases (1 case with stage Ⅰ b1 endocervical ADC and 1 case with Ⅰ b1 MDA) were diagnosed by cold knife conization,and 1 case with stage Ⅰ b1 endocervical were diagnosed by uteroscopically directed biopsy.The overall 5-year survival rate was 60.0％.Using univariate analysis results showed that age (P =0.046),stage (P =0.007),tumor size (P =0.007) and therapeutic methods (P =0.009) were significant prognostic factors.Multivariate analysis showed that therapeutic methods was an independent predictor for survival (P =0.013).Stage Ⅱ b-Ⅲ b MDA patients occupied 7/11 of all MDA patient,while there was only one such patient of 5 cases with villoglandular ADC.The overall HPV infection rate was 65％ (57/88),and there was no obvious differences about the HPV infection rates among different types of mucinous ADC.Conclusions Cervical smear cytology is of little significance to the diagnosis of mucinous cervical adenocarcinoma.Early stage mucinous ADC is difficult to be detected,especially for MDA.Cervical excisional biopsy,endocervical curettage,cold knife conization,uteroscope are beneficial to its diagnosis.Therapeutic methods is an important prognostic factor for mucinous ADC and comprehensive treatment should be given to those patients with risky postsurgical factors.

Objectives To explore the clinical symptoms, therapy and prognosis of tachycardia-induced cardiomyopathy (TIC) in children. Methods Clinical data of 22 children with TIC from July 2007 to July 2012 were retrospectively analyzed. Results TIC was mostly seen in male infants and 81.82%of TIC was caused by atrial arrhythmias. The clinical symptom relieved after arrhythmia and ventricular rates were under control with average effective treatment time of (14.00 ± 8.20) days. Ten patients had tachycardia recurrence, 7 of them had atrial arrhythmia and their clinical symptoms were improved after treatment;while 3 of them showed longer time of therapy with average treatment time of (19.50±8.40) days (P<0.05). Five children underwent radiofrequency ablation before school age and got good therapeutic effect. The post-treatment echocardiographic parameters showed cardiac function of TIC children was significantly improved after treatment, including left ventricular end-diastolic diameter index, left ventricular end-systolic diameter index, left ventricular ejection fraction and shortening score (all P<0.05). Conclusions Childhood TIC is a reversible myocardial dysfunction and its prognosis is good. TIC can be induced by various types of tachyarrhythmias and normally by atrial arrhythmia. The preferred treatment of TIC is administration of antiarrhythmic drugs but radiofrequency ablation is needed to ventricular arrhythmias induced TIC.

Objective To evaluate effectiveness of peripheral Mohs micrographic surgery for the treatment of extramammary Paget′s disease (EMPD). Methods A total of 28 patients with EMPD were treated with peripheral Mohs micrographic surgery. The depth and extent of tumor infiltration were evaluated before the surgery. One day before the surgery, 20% aminolevulinic acid hydrochloride was topically applied to determine and label surgical margins under a Wood′s lamp. After fluorescence-based localization, peritumoral skin tissues were resected and underwent frozen-section examination according to the protocol for Mohs micrographic surgery. Meanwhile, the tumor was resected. After surgery, patients were followed up every 3 - 6 months to detect local recurrence and metastasis. Results Of the 28 patients, 25 were male and 3 were female. Six patients each underwent 3 sessions of frozen-section examination, and 12 patients each received 2 sessions, with an average of 1.86 sessions for each patient. During the follow-up for 5 - 72 months, local recurrence occurred in 3 cases, and 1 patient died of tumor metastasis and uremia after 2 years of follow-up. Conclusion Peripheral Mohs micrographic surgery is a time-saving and effective treatment for EMPD.
