OBJECTIVE:To evaluate the therapeutic effect of compound glycyrrhizin plus mizolastine for patients with generalized neurodermatitis(GND)and its influence on patietents' psychology.METHODS:60 patients with GND were randomly assigned to receive compound glycyrrhizin plus mizolastine(treatment group)or mizolasitine alone(control group)for 28 days.The psychological factors were examined before and after treatment using self-rating anxiety scale(SAS),and the curative effects and the psychological changes between two groups were compared.RESULTS:The SAS scores of treatment group and control group were 30.53? 1.50 and 33.20? 1.67,respectively(P

BACKGROUND: The occurrence and severity of acute high-altitude disease(AHAD) are determined by the speed entering the highland, the altitude of highland and seasons. The association between obesity and AHAD has not been fully investigated.OBJECTIVE: To investigate the association between obesity and acute high-altitude in people exposed rapidly to the highland.DESIGN: Comparative observation.SETTING: Department of Cardiology, General Hospital of Chinese PLA and Department of Cardiology, Tibetan General Hospital of Chinese PLA.PARTICIPANTS: The experiment was conducted at the Department of Cardiology, General Hospital of Tibetan Military Area Command of Chinese PLA in August 2006. Totally 82 Henan subjects aged 28-45 years were selected from the male workers constructing the Qinghai-Tibet Railway and their managers with acute high-altitude exposure. They had never been to the highland before, and all agreed to the detection.METHODS: ①Every subject completed the AHAD self-report questionnaire at sea level and 12 hours and 24 hours after ascending high-altitude. The items in the questionnaire included symptoms of headache, gastrointestinal symptoms,fatigue or weakness, dizziness, and insomnia. Each symptom was graded from 0-3 with 0 as no symptoms, 1 as mild symptoms, 2 as moderate symptoms, and 3 as severe symptoms and a total score of 15. A score of 4 or more could by identified as AHAD. ②The height and body mass were measured to calculate the body mass (BMI). Those with BMI≥28 kg/m2 served as the obesity group [n =39, mean age (35±8) years], and those with BMI of 18.5-23.9 kg/m2 as the normal body mass group [n =43, mean age (35±8) years]. ③Arterial blood was taken to evaluate arterial oxygen saturation (SO2), arterial oxygen pressure (PaO2) and arterial carbon dioxide pressure (PaCO2) at baseline and 24 hours after ascending high-altitude. ④The measurement data was compared by t test.MAIN OUTCOME MEASURES: BMI, vital capacity of lungs, SO2, PaO2 and PaCO2 levels of obese and normal people.RESULTS: Totally 39 obese people and 43 normal people were involved in the result analysis. ①AHAD score: No symptom was reported at sea level in all participants (scored 0), but the AHAD scores in the obesity group were significantly higher than those in normal group 12-hour and 24-hour after ascending high-altitude. ②Blood gas analysis:At sea level, there were no statistical differences in the levels of SO2, PaO2, and PaCO2 between two groups (P ＞ 0.05).But 24 hours after ascending high-altitude, SO2 and PaO2 of the obesity group were much lower than in the normal group (P＜ 0.01), and PaCO2 was significantly higher than in the normal group (P＜ 0.01).CONCLUSION: Obese men are more vulnerable to high-altitude hypoxia than people with normal body mass. Obesity is an important risk factor for the development of acute high-altitude disease.

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 control the nosocomial infection and avoid the second pollution of thereclaimed medical apparatus to the washing area of supply room. Methods Count, classification and place of the reclaimed medical apparatus went along at the same self-designed categorizing pedestal of the muhi-function apparatus.No absorbing cloth was needed on the table-board, the dirty water flew into the outfall of the sewer directly and automatically, the discreteness could be unpicked, washed and lis-terized after work. Results It avoided the collision of the apparatuses, shortened the time of counting effectively and reduced the chance of pollution.It also avoided the waste of the manpower, the material resources, the time and the second environmental pollution. The effects of the two table-boards after disinfection had statistical difference (P＜0.01). Conclusions The categorizing pedestal of the mul-ti-function apparatus makes the reclaim and handling of the polluted apparatus more standard and to re-move the pollution more thoroughly.

Objective To explore the effects of cobalt chloride (CoCl2)-induced hypoxia on migration of melanoma cells, and to detect the transcription, expression and secretion of Follistatin-like 1(FSTL1) in this process. Methods B16F10 melanoma cell line was treated with CoCl2 in order to mimic hypoxia. Experimental cells were divided into three groups: 0μmol/L, 50μmol/L and 100μmol/L CoCl2 treatment groups. MTT assay was used to assure cell viability, and to determine the treatment concentration of CoCl2. Transwell assay was used to determine the migration ability of B16F10 melanoma cell line. Real-time PCR was used to measure the mRNA expression of Fstl1. Western blot assay was used to detect the intracel?lular and extracellular protein expression of FSTL1. Results The cell viability of B16F10 melanoma cell line was signifi?cantly reduced by CoCl2 treatment, with a time and concentration-dependent manner. The migration ability of B16F10 cell line was significantly increased in CoCl2 treated group compared with that of control group (P<0.05). The mRNA level of Fstl1 was obviously higher in CoCl2 treated group than that of control group (P<0.05). The intracellular expression of FSTL1 protein was consistent with the expression trend of Fstl1 mRNA. Simultaneously, the extracellular protein level of FSTL1 was significantly decreased compared with that of control group. There was no expression of FSTL1 in 100μmol/L CoCl2 treat?ment group. Conclusion The migration ability of melanoma cell line is enhanced by CoCl2 treatment, which may be associ?ated with expression and secretion of FSTL1, however, the relevant mechanism still needs further investigation.

Objective To explore the effects of different degrees of intermittent hypoxia (IH) on the activation and the secretion of extracellular matrix in MLg lung fibroblast cell line. Methods MLg lung fibroblast cells in logarithmic growth phase were exposed for 5%O2 for 100 seconds and 21%O2 for 120 seconds in 1 h, 4 h and 8 h groups (IH1, IH4 and IH8) and normoxia group (21%O2 for 8 h, N group). The cells in each group were collected at the end of experiment. Real-time PCR was used to measure the mRNA expression levels ofα-SMA and typeⅠcollagen (COL1) A1, and Western blot assay was used to detect the protein expression levels ofα-SMA and COL1. Results The mRNA and protein expression levels ofα-SMA and COL1 were significantly increased in IH1, IH4 and IH8 groups than those in N group (all P < 0.05). Furthermore, expression levels of α-SMA and COL1 showed a time-dependent increase with IH exposure time. Conclusion The intermittent hypoxia can promote the cell activation and the extracellular matrix secretion of mouse lung fibroblast cells, which may be related with the oxidative stress.

Objective To investigate the effects of uric acid (UA) and UA under oxidative stress on cultured human umbillical vein endothelial cells (HUVEC).Methocds HUVECs were incubated with different concentration UA (0,4,8,16 mg/dL),H2O2 (500 mmol/l) and UA+H2O2 (500 mmol/l) for 24,48 and 72 hours.Then we observed the morphology of HUVECs and evaluated the proliferation of HUVECs by MTT assay.NO and ET-1 in supernatant medium was detected by ELISA.Results For the viability of HUVECs,there was no statistically significant difference between 4 mg/dL UA group and control group after incubation for 24,48 and 72 hours (P＞0.05) and between UA groups(8 mg/dL and 12 mg/dL) and control group after incubation for 24,48 and 72 hours (P＞0.05).After incubation with 12 mg/dL of UA for 48 hours or 8 mg/dL of UA for 72 hours,the viability of HUVECs decreased significantly (P ＜0.05) The viability of HUVECs in H2O2 group decreased significantly (P＜0.05).The viability of HUVECs in UA+H2O2 groups after incubation for 24 h was significantly better than H2O2 group.There was no signifiant difference in the cell viability between (8 mg/dL or 12 mg/dL) UA+H2O2 group and H2O2 group.Compared with the control group,the NO levels were decreased and the ET-1 levels were increased in the supernatants of HUVECs in 12 mg/dL UA group for 72 hours (P＜0.05).Compared with H2O2 group,the NO levels were increased and the ET-1 levels were decreased in the supematants of HUVECs in (8 mg/dL or 12 mg/dL) UA +H2O2 groups for 24 hours (P＜0.05),while for (12 mg/dL) UA +H2O2 group for 72 hours,the results were just the contary.Conclusion The effects of UA on HUVECs are related with both concentration and action rime.Acutely increased UA may protect HUVECs form injury,while long action of UA may injure HUVECs,especially under oxidative stress.
