OBJECTIVE To study the risk factors of pulmonary infection and prognosis in elderly cerebral apoplectic patients. METHODS A retrospective survey on 541 elderly cerebral apoplectic patients was analyzed to investigate the rate of pulmonary infection,the type and the severity of cerebral apoplexy,the underlying disease,disturbance of consciousness,invasive operation and the prognosis. RESULTS The most of the pulmonary infections in elderly cerebral apoplectic patients were nosocomial infection.The rate of infection was high and related to many factors. CONCLUSIONS The result showed that the pulmonary infection in elderly cerebral apoplectic patients is caused by many risk factors.Controlling the rate of pulmonary infection can help us to succeed in treating cerebral apoplexy.

OBJECTIVE:To systematically evaluate the efficacy and safety of sodium valproate versus diazepam in the treat-ment of status epilepticus in adults,and to provide evidence-based reference for clinic treatment. METHODS:Retrieved from Med-line,EMBase,PubMed,Cochrane Library,CJFD,VIP datebase,CBM and Wanfang database,the randomized controlled trials (RCT) about sodium valproate (test group) versus diazepam (control group) in the treatment of status epilepticus in adults were collected. Meta-analysis was performed by using Rev Man 5.0 statistical software after extracting data and evaluating quality. RE-SULTS:A total of 5 RCTs were included,involving 276 patients. Results of Meta-analysis showed that recurrence rate of epilepsy in 48 h in test group was significantly lower than that of control group [OR=0.39,95%CI(0.16,0.96),P=0.04]. Compared with the control group,the effective rate controlling epilepsy within 2 h[OR=1.76,95%CI(0.88,3.52),P=0.11] and incidence of liver injury[RR=1.19,95%CI(0.38,3.70),P=0.77] were no significant differences. CONCLUSIONS:The efficacy and safety of sodi-um valproate was equivalent to diazepam in the treatment of status epilepticus in adults,however,sodium valproate was superior to diazepam in terms of controlling recurrent effect. Due to methodology limit of included studies,large-scale and high quality RCT are required for further validation of the conclusions.

Objective:To analyze the consistency between the histopathological results of routine endoscopy and biopsy in observing the gastric mucosa of patients with non-malignant gastroduodenal diseases,and to evaluate the necessity of biopsy following gastric endoscopy.Methods: From Jan.2005 to Dec.2005,320 patients who received upper gastrointestinal endoscopy and biopsy because of upper abdominal symptoms were included in this study.The patients were selected consecutively according to their disorders diagnosed by macroscopic endoscopy and were divided into 64 groups.The 5 patients in each group had reflux esophagitis,non-atrophic gastritis,atrophic gastritis,gastric ulcer and duodenal ulcer,respectively.Patients in the same group were matched with each other in gender,age and their history of diseases.The results of endoscopy,including the exudation,congestion,erosion,roughness,bile reflux,etc.,were read by 2 experienced endoscopists.The biopsy was performed by an experienced pathologist and pathological variables included active inflammation,chronic inflammation,atrophy,intestinal metaplasia and atypical hyperplasia.The status of Helicobacter pylori(H.pylori) infection was evaluated by rapid urea test,silver staining and histological methods;the result was deemed positive when the results of either 2 tests were positive.Results: Erosion,exudation,roughness,and H.pylori infection were related with active inflammation;erosion and H.pylori infection were related with chronic inflammation;roughness of mucosa was related with atrophy;roughness and H.pylori infection were related with intestinal metaplasia;and obsolete hemorrhage,H.pylori infection,roughness mucosa,and bile reflux were related with atypical hyperplasia.Macroscopic diagnosis rate of atrophic gastritis was 71.9%(46/64) with a false positive rate of 28.2%(18/64) and a false negative rate of 34.38%(22/64).Conclusion: Macroscopic diagnosis is indicative to pathological changes of gastric mucosa,but the predictive value is relatively poor,making biopsy and pathological examination necessary in the diagnosis of gastric mucosa disorders during routine endoscopic examination.

Objective To estimate the prevalence and associated factors of facial wrinkling in females.Methods Questionnaires were designed and delivered to collect related data on volunteers. The subjects were divided into outdoor and indoor groups. Wrinkles were classified into 9 grades based on photos taken by SIA0612 image analyzer and quantification analysis via Visioscan VC 98. SPSS 17.0 software was used to assess the associated factors of wrinkling, including sun-protective measures, skin care and cosmetology, onset age and location of wrinkles in these subjects. Results A total of 246 patients aged 19 - 71 years were recruited in this study. Sun-protective measures were applied in 13.5% of the subjects between 12 and 18 years of age,38.5% of those between 19 and 29 years of age, 39.2% of those between 30 and 39 years of age, 44% of those between 40 and 59 years of age, and in none of those between 60 and 75 years of age, 44.1% of all the subjects in the latest 5 years. Wrinkles were absent in 5.7% of the subjects, and pigmentation macules absent in 21.7%. The first development of wrinkles was mainly observed in subjects aged 30 to 35 years, and that of pigmentation macules in those aged 25 to 30 years. The most common locations of facial wrinkles, in order of decreasing frequency, were infraorbital area, lateral angle of eye, nasolabial fold, glabella in the indoor group,lateral angle of eye, infraorbital area, glabella and nasolabial fold in the outdoor group. Fishtail lines seemed to be the commonest wrinkles with an earliest onset among these wrinkles, and showed a prevalence of 100% in subjects aged 45 years or older in the indoor group, and in those aged 30 years or older in the outdoor group.Conclusions Wrinkles and pigmentation macules are dominate manifestations of skin aging in Chinese females. The onset of pigmentation macules is earlier than that of wrinkles. The main manifestations of skin aging in Chinese females, in order of decreasing frequency, are yellow-grey skin, skin dryness, roughness,leather-like appearance, teleangiectasia, and (or) severe pigmentation macules, increase in skin fragility, etc.The order and age of wrinkle appearance are different between indoor and outdoor females.

The Back-Shu points of the five Zang-organs are a group of points where qi and blood pour into the back and lumbar regions. Acupuncture at these points has a wide indication scope. However, it’s reported that internal organs were punctured in some cases because of improper control of needling depth, angle, and intensity during acupuncture. We used perpendicular needling instead of conventional oblique needling during the acupuncture of the Back-Shu points of the five Zang-organs. We found that when patients were completely relaxed, acupoints were correctly selected, the needling depth, the way of holding the needle, and inserting methods were well controlled, perpendicular needling of the Back-Shu points of the five Zang-organs can produce stronger needling sensation, and it’s easier to operate, safer, and more effective compared to oblique needling.

ObjectiveTo investigate and compare the efficacy, safety, and cost effectiveness in the treatment of painful osteoporotic vertebral compression fractures ( OVCFs ) with percutaneous vertebroplasty (PVP) and kyphoplasty(PKP). MethodsSeventy-two patients (96 vertebrae) with painful OVCFs were treated by PVP (n ＝34) or PKP (n ＝38) under radiological monitoring. After bone biopsy needle into the compressed vertebra, bone cement (polymethylmethacrylate) was injected in PVP group, and that was inserted followed by the inflation of vertebra to create cavities in PKP group. The fluoroscopy time, total amount of bone cement injected, and cost were recollected respectively. The score of visual analogue scale point( VAS, 10-point scale)was determined at before the procedures, and 24 hours, one week, and one month after the procedures.Pain relief and complications were observed.The Cobb angle and vertebral heights of the anterior, middle, and posterior border were measured pre-and post-operative. ResultsThe two procedures were technically successful in all patients. The follow-up ranged from 1. 0 to 34. 0 months [mean time, (8. 9 ±3.2) months]. The Mean fluoroscopy time of treating per vertebra in PVP group was ( 11. 1 ± 10. 6 ) min, which was significant shorter than that ( 23.5 ± 13. 0) min in PKP group( P ＜0. 05 ).The mean total cost per patient was (5127. 2 ± 502.3 ) yuan in PVP group, which were strikingly lower than that(32 301.4 ±3204. 6) yuan in PKP group (P ＜0. 05).(3)There was no significant difference( P ＞0. 05 ) in average cement volumes in PVP group [ (4. 9 ± 1.1 ) ml]and PKP group [ (5.4 ± 1.7 ) ml]. Pain relief of was observed in 94. 1％ (32/34) of PVP group and in 92. 1％ (35/38) of PKP group. The score of VAS at pre-operation was (8. 3 ±0. 4 vs 7.9 ±0. 8) ,and at post-operative 24 h (2. 9 ±0. 9 vs 2. 8 ± 1. 2),1 week (2.6 ± 0. 9 vs 2.6 ± 1. 1 ), and 1 month (2.6 ± 0. 9 vs 2. 5 ± 1.3 ) were no difference at PKP and PVP group(P ＜0.05). There was significant difference between pre- and post-operative time point in each group. The Cobb angle, anterior and middle height of vertebra was corrected in both PVP and PKP group. In PVP group, the preoperative Cobb angle, anterior and middle height of vertebra was (24. 2 ± 3.8 )°,( 19. 1 ± 1.4) mm, (25. 2 ± 1.0) mm, which was significant different ( P ＜ 0. 05 ) from that of ( 19.4 ±3.9)°, (21.0 ± 1.5) mm, (27.0 ± 1.2) mm at pre-operation.In PKP group,there was significant difference (P ＜ 0. 05 ) in the preoperative Cobb angle, anterior and middle height of vertebra [(25. 1 ±5.0)°vs(10.7 ±2.8)°, (19.5 ± 1.5) mm vs (24.3 ± 1.9) mm, (25.4 ± 1.1) mm vs (29.7 ±1.3) mm, respectively]. As to the above index, the overall correcting effect in PKP was much better than that in PVP( P ＜0. 05 ). Cement leakage occurred in 9 cases in PVP group and 3 cases in PKP group ( P ＜0. 05 ) but no symptoms. There were no major complications during operation in the two groups. Conclusion PVP and PKP are effective and safe in the treatment of painful OVCFs but PVP is more cost effective than PKP.

Objective To analyze the clinical and histopathologic features of eruptive microvenular hemangioma (EMVH). MethodsThe clinical and histological findings in six patients with EMVH were retrospectively reviewed.Results The patients were young or middle-aged,with a median age of onset of 34 years.The ratio of males to females was 1 ∶ 1.Clinically,all the patients experienced a sudden development of widespread,asymptomatic,brunneus,flat-topped papules and plaques measuring from 0.1 to 2.0 cm in diameter.Histopathologic examination revealed a poorly circumscribed proliferation of small,irregularly branched,thin-walled blood vessels haphazardly arranged between collagen fiber bundles in the dermis.The lumina of the blood vessels were often collapsed.There was no cellular atypia or mitosis.A variable degree of sclerosis was noted in the surrounding stroma.Immunobistochemical study revealed that the endothelial cells stained positive for CD34,CD31,and factor Ⅷ-related antigen.Conclusions The diagnosis of EMVH is proposed,and awareness of this disease may benefit its early diagnosis and avoidance of unnecessary treatment.

Potassium metabolism in young adult men exercising in the heat for six consecutive days and the effect of potassium deficiency in mice and rats induced by low potassium diet during heat exposure were observed. Increased potassium loss in sweat and lower potassium intake resulted in negative potassium balance. Individuals with a negative potassium balance had lower se- rum potassium levels and higher body temperature after exercise. Potassium deficient mice accomplished less work done (2.372 vs 4.253 Kg.M) but exih-ibited a markedly greater rate of heat gain (1.36 vs 0.87℃/Kg.M) as compared to the controls. The survival rate and cellular energy metabolism also decreasedThese observations suggest that prevention from potassium deficiency must be emphasized during prolonged physical activity under hot environments. According to the linear regression equations between potassium intake and balance, it is proposed that the potassium requirements in mild and medium physical activity in the heat are 40 and 60 mEq/day respectively, and the allowance of potassium in the latter may be 70-80 mEq/day.

OBJECTIVE To understand nosocomial candidal infection among tuberculosis patients and its drug(sensitivity).(METHODS) Totally 6280 clinical samples from Jan 2002 to Dec 2004 were cultured;and part of(positive) ones were tested their drug sensitivity to FC,FLC,KET and ITC.RESULTS From all cultured samples 2767 Candida strains(positive rate was 44.06%) were isolated.From them C.albicans,C.glabrata,C.tropicalis,C.krusei and other Candida were 2006, 344,206,95 and 116 strains,their positive rate was 31.94%,(5.48%),3.28%, 1.51% and 1.85%,respectively.Their drug sensitivity rate to four drugs were as follows: to FC was 93.73%,to TTC 62.76%,to FLC 51.03% and to KET was 47.59%. CONCLUSIONS The condition of(tuberculosis) patient would become serious due to higher dual infection rate by Candida after too long anti-(tuberculosis) treatment.Among the four kinds of drugs the FC has the best anti-candidal activity.
