Objective: To observe the clinical efficacy of combining two needling manipulations, Er Long Xi Zhu (two dragons playing with a pearl) and Guo Yan Re (heat produced to reach the eyes), in treating dry eye syndrome (DES) of lung-yin deficiency pattern. Methods: Fifty-six eligible DES patients of lung-yin deficiency were randomized into an observation group and a control group, with 28 cases in each group. Same acupoints were selected in the two groups: Cuanzhu (BL 2), Sizhukong (TE 23), Taiyang (EX-HN 5) and Fengchi (GB 20) were chosen as the major points and Feishu (BL 13) and Chize (LU 5) as the adjuvant. Er Long Xi Zhu and Guo Yan Re needling manipulations were applied in the observation group while twirling reinforcing manipulation was used in the control group. Treatment was conducted once per day in both groups, for two sets of 15 consecutive days at a 2-day interval. Changes in the symptom score, tear break-up time (BUT) and tear production were observed afterwards, and the clinical efficacy was also compared between the two groups. Results: The total effective rate was 92.8％ in the observation group, higher than 71.4％ in the control group, and the between-group difference was statistically significant (P<0.05). After treatment, the symptom score, tear BUT and tear production showed significant improvements in both groups (all P<0.05); the symptom score, BUT and tear production in the observation group were significantly different from those in the control group (all P<0.05). Conclusion: Given the same acupoint selection, combining Er Long Xi Zhu and Guo Yan Re needling manipulations can produce more significant clinical efficacy than twirling reinforcing manipulation in treating DES of lung-yin deficiency pattern.

Objective To research the effect mechanism of ultrashortwave in the correlation of ultrashortwave and the tail replantation, provide the experiment basis of clinical practice of prevention and cure for the vascular crisis after micromodule anastomosis. Methods Eighty Sprague-Dawley(SD) rats of clean grade were 3-month-old,female,and were divided into four groups:control group (group 0),model group (group 1 ),contrast group (group 2),ultrashortwave (USW) group (group 3).The preparation of tail replantation model was cut off soft tissue except for caudal veins on both sides of the tail. The coccyx was not broken away from tail.At last,the audal artery under abdominal main centre ditch was anastomosed.In experiment process, the USW group was divided into high dosage group (group 3A) and low dosage group (group 3B). The caudal arterys were ligated and not anastomosed in the group 0. Caudal arterys in other groups were anastomosed.Rats in the group 0 and group 1 received no treatment,normal management after the operation. Rats in the group 2 were given abdominal cavity injection of papaverin liquid immediately,then once a day to 5 days after the tail replantation.Rats in the group 3 were immediately given USW therapy of twenty minutes on the anastomosis section,and then once a day for 5 days after the tail replantation.The USW dosage of group 3A was 3th grade and 50mA. The USW dosage of group 3B was 2th grade and 28mA.The survival rate of the rat tails was observed after the tail replantation for 10 day.Before being grouped,it was measured that the tail skin temperature diference between near and far side of anastomosis section.After the tail relpantation, the temperature diference was inspected daily for 10 postoperative days hence. Before rats were grouped and the eighth hour after the tail replantation, rats were collected blood plasma specimens and measured contents of nitric oxide with destination colorimetric mathods of nitric oxide.Results Carrying out comparison of survival rate of every group,the output weve:between tail cutting off group (group 0,0) and tail replantation group (group 1,2,3,43.94％) to compare P ＞ 0.05; between each group of the tail replantation groups (1,2,3A,3B group) to compare P＞ 0.05,group 3B ＜ 2 ＜ 1 ＜ 3A; between group 3B and group 1 to compare P ＞ 0.05; between group 2 and group 1 to compare P ＞ 0.05. Each group were compared with the change daily between postoperative and preceding operative the skin temperature diference,single-factor analysis of variance (One-Way ANOVA) analysis:Postoperative 1 day,group 3A ＜ 1,P ＜ 0.05.Postoperative 6 day:3A ＜ 3B ＜ 1 ＜ 2,P ＞ 0.05.Postoperative 7 day:group 3B ＜ 1 ＜ 3A ＜ 2,P ＜ 0.05.Each group were compared with the change of the content of nitric oxide between postoperative 8 hour and preceding operative,with rank-sum test:group 3B ＞ 3A ＞ 2 ＞ 1 ＞ 0,H =33.760,P ＜ 0.05,shows statistically significant.Conclusions USW therapy,especially USW low-dose therapy,can reduce vascular crisis and improve the survival rate of replanted rat tails,after the postoperative 1,6,7 days,reduce skin temperature,improve blood supply,improve nitric oxide at postoperative eighth hour,prevent vascular crisis.Rat tail replantation model in this experiment is feasible.

AIM To observe the curative effects of Modified Buzhong Yiqi Decoction (Codonopsis Radix,Astragali Radix,Atractylodis macrocephalae Rhizoma,ect.) on perioperative period of intertrochanteric fractures in elderly patients with Qi deficiency and blood stasis type.METHODS One hundred and twenty cases of elderly intertrochanteric fractures were randomly divided into treatment group and control group,60 cases in each group.All patients underwent closed fracture reduction and proximal femoral nail anti-rotation (PFNA) fixation.During the perioperative period,the control group only received conventional treatment,while the treatment group received conventional treatment and Modified Buzhong Yiqi Decoction once a day.The levels of interleukin-6 (IL-6),interleukin-10 (IL-10) and tumor necrosis factor (TNF-α) of both groups in preoperative and in the 1st day,the 7th day,the 14th day of postoperative were observed and compared.The complications and the curative effects according to the Harris score also were observed and compared between the two groups.RESULTS In preoperative,there was no significant difference in levels of IL-6,IL-10 and TNF-α between the two groups (P ＞ 0.05).The levels of IL-6 and TNF-α in the 1 st day of postoperative in the control group were significantly higher than those in the treatment group (P ＜0.05,P ＜0.01).And the levels of IL-10 were similar between the two groups (P ＞0.05).In addition,in the 7th day and the 14th day of postoperative,the levels of IL-6,IL-10 and TNF-α in both groups were all decreased,moreover,the descent degree in treatment group was more significant than those in the control group (P ＜ 0.05,P ＜ 0.01).The treatment group had the lower incidence of complications and the higher curative effects than those in the control group,both differences were statistically significant (P ＜0.05).CONCLUSION Modified Buzhong Yiqi Decoction applying to the perioperative period of femoral intertrochanteric fractures in elderly patients with Qi deficiency and blood stasis,can effectively reduce the perioperative inflammatory response,reduce the incidence of postoperative complications,and improve the curative effects.So it has a positive effect on the rehabilitation for the traumatic patients and is worthy of clinical promotion.

Copy number aberrations (CNAs) in chromosome arm 8q have been associated with unfavorable clinical outcomes of several cancers and progressive tumor characteristics of hepatocellular carcinoma (HCC).This study was to identify correlation of CNAs in 8q with clinical outcomes of HCC patients,and further screen for differentially expressed genes in outcome-related CNAs.Array comparative genomic hybridization and expression arrays were performed to detect CNAs and expression levels,respectively.The correlations between CNAs in 8q and outcomes were analyzed in 66 patients,with a median follow-up time of 45.0 months (range,2.6-108.6 months).One hundred and nine cases were further evaluated to identify differentially expressed genes in the potential outcome-related CNAs.Copy number gain in 8q was observed in 22 (33.3 ％) of the 66 HCC cases.The most recurrent gains (with frequencies ＞20％) were 8q13.3-21.3,8q21.3-23.3,8q23.3-24.13,8q24.13-24.3,and 8q24.3.Survival analysis showed that 8q24.13-24.3 gain was significantly associated with reduced overall survival (P=0.010).Multivariate Cox analysis identified 8q24.13-24.3 gain as an independent prognostic factor for poor overall survival (HR=2.47;95％CI=1.16-5.26;P=0.019).A panel of 17 genes within the 8q24.13-24.3 region,including ATAD2,SQLE,PVT1,ASAP1,and NDRG1 were significantly upregulated in HCCs with 8q24.13-24.3 gain compared to those without.These results suggest that copy number gain at 8q24.13-24.3 is an unfavorable prognostic marker for HCC patients,and the potential oncogenes ATAD2,SQLE,PVT1,ASAP1,and NDRG1 within the regional gain,may contribute coordinately to the 8q24.13-24.3 gain-related poor prognosis.

BACKGROUNDAcute lung injury (ALI) is a common syndrome associated with high morbidity and mortality in emergency medicine. Cell apoptosis plays a key role in the pathogenesis of ALI. Hydrogen sulfide (H(2)S) plays a protective role during acute lung injury. We designed this study to examine the role of H(2)S in the lung alveolar epithelial cell apoptosis in rats with ALI.

METHODSSixty-nine male Sprague Dawley rats were used. ALI was induced by intra-tail vein injection of oleic acid (OA). NaHS solution was injected intraperitonally 30 minutes before OA injection as the NaHS pretreatment group. Single sodium hydrosulfide pretreatment group and control group were designed. Index of quantitative assessment (IQA), wet/dry weight (W/D) ratio and the percentage of polymorphonuclear leukocyte (PMN) cells in the bronchoalveolar lavage fluid (BALF) were determined. H(2)S level in lung tissue was measured by a sensitive sulphur electrode. Apoptosis was evaluated by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining and Fas protein was measured by immunohistochemical staining.

RESULTSThe level of endogenous H(2)S in lung tissue decreased with the development of ALI induced by OA injection. Apoptosis and Fas protein in alveolar epithelial cells increased in the ALI of rats but NaHS lessened apoptosis and Fas protein expression in alveolar epithelial cells of rats with ALI.

CONCLUSIONEndogenous H(2)S protects rats from oleic acid-induced ALI, probably by inhibiting cell apoptosis.

OBJECTIVETo study the diagnosis and treatment of glucagonoma.

METHODSA retrospective review of glucagonoma cases was committed between June 1993 and July 2008 in Peking Union Medical College Hospital. It was measured by sex, age, misdiagnosis, clinical symptoms, laboratory data, imaging studies, diagnosis, treatment procedures and so on.

RESULTSThe tumors of eleven cases were found in the tail, and one case was in the head of the pancreas at the same time. Ten had solitary lesion, one had multiple lesions. The average diameter of the lesions was 3.9 cm. Nine patients had the metastasis out of pancreas and all of them had the liver metastasis. One case was a member of multiple endocrine neoplasia type 1 (MEN-1) syndromes. Eight patients being treated with operation had the detailed pathological reports. The glucagon was detected by immunohistochemistry and was positive in five patients. Six patients were pathologically malignant. Multimodal treatments included tumor resection, chemoembolization, treated with somatostatin analogues and (or) radionuclides and so on were applied to all patients.

CONCLUSIONSGlucagonoma is a rare pancreatic endocrine tumor. Radical tumor surgery is used as the first choice. Multimodal approach may improve the prognosis.

OBJECTIVETo investigate the plasma level of extracellular histones in patients with silicosis, and to explore the role of extracellular histones in the pathogenesis of pulmonary fibrosis in silicosis.

METHODSSixty-two patients with silicosis were enrolled as the silicosis group, consisting of 23 patients with stage I silicosis, 25 with stage II silicosis, and 14 with stage III silicosis; sixty workers who had a history of occupational exposure to silica dust for more than 2 years and had not been diagnosed with silicosis were enrolled as the silica dust exposure group; sixty-five healthy workers without a history of occupational exposure to dust were enrolled as healthy controls. Enzyme-linked immunosorbent assay was applied to measure the plasma levels of plasma extracellular histone (H4) and transforming growth factor-β(TGF-β).

RESULTSCompared with healthy controls [(0.82±0.67) μg/ml], the silica dust exposure group[(4.14±2.85) μg/ml] and silicosis group[(9.50±5.04) μg/ml] had significant increases in plasma level of H4 (P<0.01). The plasma level of H4 was significantly correlated with the stage of silicosis(r=0.8955, P=0.0388). The silicosis group had a significantly higher plasma level of TGF-β than the silica dust exposure group and healthy controls(P <0.05). In the patients with silicosis, the plasma level of H4 was significantly correlated with that of TGF-β(r=0.5375, P<0.01).

CONCLUSIONThe plasma level of extracellular histones increases significantly in the pathogenesis of silicosis, and extracellular histones may play an important role in the progression of fibrosis in silicosis.
