ObjectiveTo evaluate totally laparoscopic Meckel's diverticulectomy in comparison with laparoscopic-assisted or open diverticulectomy.MethodsThe clinical data of 58 cases of Meckel's diverticulum admitted between January 2006 and January 2011 were analyzed.Cases were divided into three groups according to different period of time. As a result,totally laparoscopic surgery was performed in 13 cases,laparoscopic-assisted resection in 25 cases and open diverticulectomy in 20 cases. Totally laparoscopic group was compared with the other two groups in operation time,flatus defecation time,the incidence of postoperative complications and postoperative hospital stay.ResultsThe mean length of incision was ( 1.6 ± 0.4 ) cm,the mean operation time was ( 41 ± 5 ) min,flatus defecation time was (21.2 ±3.7) h,and the postoperative hospital stay was (6.3 ± 1.2) d in totally laparoscopic group.While that was (2.5 ± 1.2 ) m,( 38 ± 2 ) cm,( 23.6 ± 4.2 ) h,( 6.5 ± 2.3 ) d,respectively in laparoscopicassisted group,and the mean length of incision was (5.0 ± 2.2 ) cm,the mean operation time was (51 ± 6 )min,flatus defecation time was (32.3 ± 6.7) h,the postoperative hospital stay was (8.4 ± 3.8) d in open surgery group.Compared with conventional laparotomy,laparoscopic techniques enjoy advantages of minimal invasion,shorter operative time,fewer complications,shorter recovery period and earlier gastrointestinal recovery(P ＜ 0.05). There were nosignificant differences in operative time, recovery period and complications between totally laparoscopic group and laparoscopic-assisted group.ConclusionsTotally laparoscopic Meckel's diverticulectomy is safe,effective and miniinvasive in experienced hands.

OBJECTIVETo explore the distribution, combination and evolution of various syndromic etiologies of erectile dysfunction (ED) based on the syndrome etiology theory.

METHODSUsing the ED Syndromic Etiology Scale, we collected the clinical data on the Chinese medicine diagnoses of 297 cases of ED, extracted the core syndromic etiologies by analysis of principal components and factors, and analyzed the patterns of distribution, combination, and evolution of ED syndromic etiologies according to the general information of the patients.

RESULTSThrough analysis of principal components and factors, 9 core syndromic etiologies were extracted, i. e. , liver constraint with qi stagnation, kidney yin deficiency, damp-heat, liver constraint transforming into liver-fire, blood stasis, kidney yang deficiency, heart-spleen paired deficiency, qi-yin paired deficiency, and phlegm-damp. Each of these syndrome etiologies exhibited its own specific distribution patterns. Of the total number of cases studied, 51.52% had 2 or 3 core syndromic etiologies and 36.03% had only one.

CONCLUSIONIn the early stage of ED, its syndromic etiologies are usually liver constraint with qi stagnation, kidney yin deficiency, damp-heat, liver constraint transforming into liver-fire, and blood stasis. With the natural progres- sion of the disease, its syndromic etiologies gradually evolve into kidney yang deficiency, heart-spleen paired deficiency, qi-yin paired deficiency, phlegm-damp, and blood stasis, and finally into yin-yang deficiency of the heart, spleen and kidneys, combined with phlegm-damp and blood stasis.

OBJECTIVETo explore the effect of combination therapy of tetramethylpyrazine (TMP) with methotrexate (MTX) on collagen induced arthritis (CIA) rats.

METHODSTotally 55 male SD rats were stratified by body weight. Nine of them were randomly recruited as the normal control group. The rest 46 were immunized with type II bovine collagen (C II) for establishing rheumatoid arthritis (RA) model. Forty successfully modeled rats were randomly divided into 4 groups according to swollen toe degree, i.e., the CIA group, the TMP group, the MTX group, and the TMP plus MTX group, 10 in each group. Rats in the MTX group were administered with MTX (1. 2 mg/kg) , once per week for 4 continuous weeks. Those in the TMP group were administered with 40 mg/kg TMP, once per day for 10 continuous days, and then discontinued for 7 successive days, and continued for another 10 successive days. Rats in the TMP plus MTX group were administered with a mixture of equal dose MTX and TMP, and when MTX was discontinue, TMP was administered according to the way in the TMP group. Equal volume of saline solution was given to rats in the normal control group and the CIA group. Clinical parameters including ankle width (mediolateral diameter) and hindpaw swelling were measured at day 0, 4, 11, 18, and 26 after treatment. Rats were sacrificed 28 days after treatment, their knee joints and ankle joints were collected for pathological analyses. Serum levels of IL-1β, IL-6, and IL-17A were detected by ELISA. Changes of fibrinogen (FIB) and platelet aggregation rate (PAg) were detected.

RESULTSCompared with the normal control group, the ankle width and hindpaw swelling increased significantly (P < 0.01), contents of FIB and PAg increased obviously (P < 0.05, P < 0.01), serum levels of IL-1β, IL-6, and IL-17 increased remarkably (P <0. 01) in the CIA group. Obvious cell proliferation, inflammatory cell infiltration, hyperemia and edema of synovial tissues could be seen. Pannus formed and immerged in cartilages, resulting in necrosis. Compared with the model group, changes of ankle width and hindpaw swelling were all alleviated in each medicated group (P <0. 05, P <0. 01). Of them, the effect was superior in the MTX group to that of the TMP group and the MTX plus TMP group (P < 0.05, P < 0.01). Contents of FIB, serum levels of IL-1β and IL-6 decreased significantly in the MTX group (P < 0.05). Contents of FIB, serum levels of IL-1β and IL-6 decreased significantly in the TMP group and the MTX plus TMP group (P < 0.05). Besides, serum levels of FIB and IL-6 were obviously lower in the MTX plus TMP group than in the TMP group and the MTX group (P < 0.01). Levels of PAg and IL-17A were more significantly lowered in the TMP group than in the MTX plus TMP group and the MTX group. Pathological changes could be alleviated in each medicated group, with the optimal effect obtained in the MTX plus TMP group.

CONCLUSIONCombination of TMP with MTX could significantly ameliorate inflammatory reactions and FIB contents of CIA rats.

Methods The rat model of anal edema was induced with carrageenan injection. Ninty six SD rats were divided into early intervene and latter intervene batches, every batches were randomly divided into six groups; normal control group 1, normal control group2, model matched groupl, model matched group2, hip bathing with TCM groupl, hip bathing with TCM group2. Hip bathing time duration were lOminutes and 20minutes. The rehabilitation of rats anal edema were observed. Results The comparison has been made among edema area, the ratio of dry/wet weight, microcirculation change, skin temperature, the difference is statistically significant in TCM early intervene hip bathing groups (P < 0. 05). There was a significant difference of edema proportion with 20 minutes duration between TCM hip bathing groups and model control groups (P < 0. 01 ). The comparison has been made among the ratio of dry/wet weight, microcirculation change, the difference is statistically significant in TCM latter intervene hip bathing groups(P< 0. 05). Histopathological examination showed local tissue inflammatory cell infiltration, the loosen degree of tissue space and capillary congestion of modle group were improved. Conclusions Hip bathing with traditional Chinese medicine in early intervene have obvious effect on rehabilitation of rats with anal edema, which can dispell anal edema, improving microcirculation could descend the temperature and promote the rehabilitation of anal edema, relieve inflammation and hyperemia. In the respect of edema proportion relieving, hip bathing with 20 minutes duration showed better effect than 10 minutes.

OBJECTIVE To study the effects of Qishen capsule against focal cerebral ischemia reperfusion injury in rats.METHODS The rat model of focal cerebral ischemia-reperfusion was established with the middle cerebral artery occlusion (MCAO)by reversible inserting a nylon thread method. Rats were killed after ischemia 1 hour and reperfusion 2 hours. Brain were fetched out and measured the contents of H2 O, [ Ca2 + ] i, NO, neurological function evaluation and infarct volume and the activities of NOS,Ca2+ -ATPase, Na+ , K+- ATPase. The sections were stained with hemotoxylin-eosin(HE) or TTC, histological changes of brain were observed. RESULTS Compared with sham operation group, H2 0 and [ Ca2 + ] i, NO contents were lower significantly and the activity Qishen capsule has protective effects on cerebral ischemia-reperfusion lesion.

OBJECTIVETo explore the possibility of further improvement of the efficacy of neoadjuvant chemoradiotherapy in locally advanced lower rectal cancer and the management of patients with clinical complete regression.

METHODSFrom May 2001 to August 2007, 192 cases with locally advanced lower rectal cancer (T3/T4 or N(+)) received preoperative radiotherapy 40 - 46 Gy/20 - 23 fractions and concomitant oral capecitabine 625 mg/m(2) bid for 10 weeks prior to surgery. Curative resection with total mesorectal excision (TME) was carried out 6 weeks after the end of radiation.

RESULTSAs a result, 117 cases (60.9%) experienced adverse events but only 2 suffered from G3 side effects. Seventeen cases (8.9%) had a clinical complete tumor regression without surgery; 175 patients underwent curative resection, of them 134 cases with low anterior resection (LAR), 32 cases with ultra-low anterior resection with Park's coloanal anastomosis (6 cases with diverting temporary colostomy) and 9 cases with abdominal pelvic resection (APR). Sphincter preservation was achieved in 94.9%. Twenty-four patients (12.5%) got pathological complete response (CR), 17 patients with clinical CR and the overall CR rate was 21.4%. According to the pathological staging post operation: T0N0 41 cases, T2N0 43 cases, T3N0 77 cases, T4N0 5 cases, T2N1 11 cases, T3N1 13 cases, T4N1 2 cases; Graded under Dworak's tumor regression: TRG0 8 patients, TRG1 32 patients, TRG2 28 patients, TRG3 83 patients and TRG4 24 patients, with an overall pathological tumor downstaging in 77.14%. No operative death occurred, 5 patients suffered from rectovaginal fistulas and 4 anastomotic leakages with an overall anastomotic leakage rate of 5.1% (9/175) and all the patients recovered uneventfully after properly managed. All patients were followed up for a median time of 42 months (range, 12 - 87 months). During the time, 11 patients developed lung metastases, 6 liver metastases and 7 had local recurrences. The 3 years disease-free survival (DFS) was 86.6% and overall survival (OS) was 92.6%.

CONCLUSIONSNeoadjuvant chemoradiotherapy has high efficacy in locally advanced lower rectal cancer, resulting in tumor down-staging, improved resectability and sphincter preservation, and reduced local recurrences. Meanwhile the cases with clinical complete response can be followed up closely and safely without surgery.

OBJECTIVETo evaluate the role of transbronchial lung biopsy (TBLB) pathology in pneumoconiosis diagnosis.

METHODSDuring Jan 2003 to Jun 2010 in our hospital. 418 patients exposed to dusts were examined with TBLB. The chest radiographs of all subjects showed the pneumoconiosis-like opacities. Because the dust property or accumulated doses didn't match with abnormality on chest radiographs or there were no a series of chest radiographs, it was required for subjects to perform the TBLB for diagnosis. Three hundred seventy nine cases with satisfying samples served as the study subjects. The dust deposition, fibrosis and birefringent particles were found in TBLB pathological examinations. From May 2005, the Prussian blue iron reaction test was conducted on the TBLB samples. A panel made pneumoconiosis diagnosis according to GBZ 70-2002 and GBZ 70-2009 Pneumoconiosis Diagnostic Criteria, consulting subjects' accounts and pathologic results.

RESULTSAmong 379 subjects, 376 cases (99.2%) showed the lung interstitial fibrosis, 228 cases (60.2%) demonstrated the dust deposition, 111 cases (29.3%) expressed the birefringent particles by polarized light microscopy. Birefringent particles positive rate was 37.8% (62/164) in 164 patients exposed to either silica or potter dusts or cement dusts or coal-silica dusts or foundry dusts, which was much higher than that (22.7%, 49/215) in patients exposed to other dusts (welding fume or asbestos or aluminum dusts) (P < 0.05). The positive rate of Prussian blue iron reaction in 177 patients exposed to welding fume or burnishing dusts was 53.1% (94/177), which was significantly higher than that (23.2%, 13/56) in patients exposed to other dusts (cement dusts, casting dusts or silica) (P < 0.001). There were no significantly differences in rates of lung fibrosis, dust deposition and birefringent particles between pneumoconiosis and none-pneumoconiosis subjects. The rate of lung fibrosis in pneumoconiosis cases was significantly higher than that in non- pneumoconiosis cases (P < 0.05).

CONCLUSIONTBLB could provide the evidence of exposure to dusts and pathological changes, which may be useful to the pneumoconiosis diagnosis.

Objective　To explore the effect of nordihydroguaiaretic acid (NDGA) on the expressions of vascular endothelial growth factor (VEGF) and its receptor, kinase-inserted domain containing receptor(KDR) and the possible mechanism. Methods　The expression of VEGF in human malignant glioma cell line SHG-44 and that of KDR in human umbilical vein endothelial cell (HUVEC) line ECV-304 were observed 1～3 d after NDGA treatment with immunohistochemistry, in situ hybridization and image analysis. Results　The expression of VEGF was declined at protein or mRNA levels in SHG-44 cells after treated with 100 μmol/L NDGA for 1 to 3 d. The expression of KDR in endothelial cells with 100 μmol/L NDGA treatment for 1 to 3 d was decreased too, in a more obvious way compared with the decline of VEGF expression in SHG-44 cells. Conclusion　The results suggest that NDGA inhibits the expression of VEGF in glioma cells as well as that of VEGF receptor KDR in endothelial cells, which may be the important molecular mechanism of anti-angiogenesis of NDGA.
