Objective To investigate the expression of pro-irtilammatory mediator in peripheral blood of patients with severe sepsis treated by different therapeutic dose of high-volume hemofiltration (HVHF). Methods According to the standard of severe sepsis, 83 cases were randomly divided into three groups, A group [60 ml/(kg·h)], S group[80 ml/(kg·h)], C group[100 ml/(kg·h)], respectively. The levels of TNF-α, IL-1, IL-8 in plasma of patients were measured by enzyme-linked immunosorbent assay (ELISA) before treatment and at 2, 4, 6, 8, 10 h after treatment, and the grades of APACHEⅢ were evaluated at every time-point simultaneously. Results The grades of APACHEⅢ were lower after treatment than those before treatment (P<0.05), but the decreases between every group had no significant deviation (P>0.05). The levels of TNF-Ⅲ, IL-1, IL-8 in plasma of patients were all decreased gradually after treatment. Compared with those before treatment, the levels of TNF-α,IL-1 and IL-8 at 2, 4 and 6 h after HVHF were obviously decreased (P<0.05). The levels of TNF-α, IL-1 and IL-8 were lightly increases at 4 and 6 h after HVHF, but they were lower that those before treatment (P<0.05). At every time-point, the levels of TNF-α, IL-1, IL-8 trended to decrease following the increase, of displacement liquid volume, the mean levels of pro-inflammatory mediator in C group were markedly reduced compared with the levels in A group (P<0.05). Conclusion HVHF can decrease the levels of pro-inflammatory mediator in peripheral blood of patients with severe sepsis and the grades of APACHEⅢ, the more the therapeutic dose of HVHF, the lower the levels of pro-inflammatory mediator.

Objective To explore the efficacy of Xipayigingiva consolidation gargle for root canal flushing. Methods 543 teeth in 543 patients with acute or chronic pulpitis or apical periodontitis who needed root canal treatmentwere divided into three groups by completely randomized design. The three groups wereXipayigingiva consolidation gargle group, hydrogen peroxide group, and sodium hypochlorite group. Conventional pulp chamber incision, pulpectomy and root canals preparation were used for the affected teeth. Three different rinsing solutions were applied to flush root canal. One week later , signs and symptoms were observed , and success rate was assessed in patients by comparing among the three groups. Results Regardless of duration of disease course and patients′ oral health situation, the success rate did not differ significantly among the three groups (P > 0.05). Conclusions Xipayi gingiva consolidation gargle has the same effect as sodium hypochlorite and hydrogen peroxide. It can be used as an alternative for flushing root canal.

OBJECTIVETo compare video-assisted thoracis surgery (VATS) and mini-incision thoracotomy for the treatment of benign esophageal diseases.

METHODSThe clinical data of 52 patients with benign esophageal diseases underwent minimally invasive surgical treatment from January 1995 to January 2007 were analyzed retrospectively. VATS were performed in 25 cases and mini-incision thoracotomy were performed in 27 cases.

RESULTSThere was no operative death or major perioperative complications in both groups. There were no significant difference between them according to operation time, postoperative thoracic drainage time, postoperative gastric drainage time and postoperative hospital stay time.

CONCLUSIONSFor the treatment of benign esophageal diseases, both VATS and mini-incision thoracotomy are safe and effective. VATS can be performed in suitable cases with more minimal incision and decreased operative trauma, mini-incision thoracotomy can be performed in almost all cases, preferring the sophisticated cases.

OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

Objective To clone and express the human asialoglycoprotein receptor(ASGPR) H1 subunit, purify and identify the immunoreactivity of the recombinant protein, and establish the enzyme linked immunosorbent assay (ELISA) to detect anti-ASGPR antibodies in diagnosis of autoimmune hepatitis. Methods The CRDHI cDNA (435 bp) was subcloned into eukaryotic vector PEGH, and the recombinant protein expression was induced by D (+)-Galactose. The recombinant CRDH1 was purified with Glutathione Sepharose 4B, and its immunoreactivity was identified by SDS-PAGE and western blot as well as MALDI-TOF. ELISA was established to detect the anti-ASGPR antibodies in serum samples of 45 patients with AIH, 30 patients with SLE, 30 patients with RA, 10 patients with SS and 30 normal controls. Results The sequencing of recombinant plasmid showed the CRDH1 gene was successfully inserted to the eukaryotic expression vector with correct sequence and open reading frame. The fusion protein showed a molecular weight of 42 500 Da on SDS-PAGE gel and confirmed to be the human ASGPR by MALDI-MS through peptide mass fingerprint analysis with Mascot in human protein database. It shared 98. 34% homology with ASGPR H1 subunit. Western blot analysis showed that the fusion protein had the same immunoreactivity as human ASGPR. The results of ELISA indicated that the positive rate of anti-ASGPR was 35.6% ( 16/45 ), but the ELISA was negative in other control. There was significant difference of positivity of the autoantibodies between AIH and non-AIH controls (χ2 = 31.85,P < 0. 01 ). Conclusions The human plasmid containing ASGPR is successfully clone into Saccharomyces cerevisiae Y258. The recombinant autoantigen owns good antigenicity and specificity. ELISA established with the purified protein shows good specificity for diagnosis of AIH.

Structural alterations in fibroelastic components of the penile corpus cavernousum (CC) may impair its compliance, resulting in venous leakage and erectile dysfunction (ED). Our study evaluated the effectiveness of noninvasive two-dimensional shear-wave elastography (2-D SWE) in quantifying penile CC lesions in rabbits with hyperlipidemia-induced ED. A total of 12 New Zealand white rabbits were randomly divided into two groups. Six were fed a high-cholesterol diet containing 2% cholesterol and 8.5% lard for 10 weeks and the other six were fed normal diet as controls. We measured the shear-wave elastic quantitative (SWQ) value of penile CC by 2-D SWE. Erectile function was investigated by intracavernous injection of papaverine, and immunohistochemical (IHC) staining and the western blot analysis to determine the penile CC lesions. After 10 weeks, the SWQ values obtained from penile CC were remarkably higher in the high-cholesterol-fed compared with the control group, and the ΔICP (ICP plateau minus ICP baseline)/MAP (ICP: intracavernous pressure, MAP: mean arterial pressure) was markedly decreased. The IHC staining and western blot revealed extracellular matrix (ECM) accumulation in penile cavernous tissues, and the smooth muscle cell (SMC) phenotypic transition was affected, as indicated by reduced alpha-smooth muscle actin and calponin-1 expression and increased phospho-myosin light chain20 (p-MLC20)/MLC20 and osteopontin expression. Hyperlipidemia resulted in ECM accumulation accompanied with SMC phenotypic transition in penile CC and impaired the erectile function eventually. These might, in turn, lead to variations in the SWQ values. It suggests that 2-D SWE may be a novel, noninvasive and effective approach that distinguishes penile CC lesions secondary to hyperlipidemia from normal.

Objective : To explore the pregestational and gestational risk factors associated with small for gestational age infant (SGA) by dif-ferent degrees. Methods ¡¤ Mothers and single newborns delivered at Xinhua Hospital, Shanghai Jiao Tong University School of Medicine from September 2013 to December 2016 were included. Multivariate Logistic regression was used to analyze the correlation between maternal preg-nancy and pre-pregnancy risk factors and the occurrence of SGA by different degrees. Results ¡¤ There were no statistically significant differ-ences in maternal age, number of birth, education level, incidence of preterm birth and fetal sex in SGA. Maternal body mass index (BMI), gesta-tional hypertension and accepting assisted reproduction were significantly correlated with SGA (all P<0.05). The incidence of moderate SGA in mothers with low pre-pregnancy BMI and gestational hypertension were 3.6 and 4.0 times higher than that of the mothers with normal BMI and blood pressure. The incidence of severe SGA in mothers receiving assisted reproduction was 6.4 times higher than that in those who did not. Mild SGA was not associated with the above risk factors. Conclusion ¡¤ Maternal low BMI and hypertension are the risk factors of moderate SGA and accepting assisted reproduction are the risk factors of severe SGA, and the risk factors of SGA by different degrees are not the same.

Objective: To observe the effect of electroacupuncture (EA) pretreatment on the protein expression of c-fos in fastigial nucleus (FN) and lateral hypothalamus area (LHA) in rats with acute myocardial ischemia-reperfusion injury (MIRI), and to explore the role and mechanism of FN and LHA in EA at the Heart Meridian fighting against acute MIRI reaction. Methods: Seventy Sprague-Dawley rats were randomly divided into a sham operation group, a model group, an EA-Heart Meridian group and an EA-Lung Meridian group, with 14 rats in each group; an LHA lesion plus EA-Heart Meridian group (LHA+EA-Heart Meridian group) and a FN lesion plus EA-Heart Meridian group (FN+EA-Heart Meridian group), with 7 rats in each group. Except the sham operation group, the left anterior descending branch of coronary artery was ligated to establish acute MIRI rat models in the other 5 groups. In the three groups with EA-Heart Meridian treatment, Shenmen (HT 7) and Tongli (HT 5) were selected; Taiyuan (LU 9) and Lieque (LU 7) were selected in the EA-Lung Meridian group. All the EA groups received EA stimulation prior to modeling, with 1 mA in current intensity and 2 Hz in frequency, 20 min each time, once a day for a total of 7 d. The sham operation group and the model group did not receive EA stimulation. The electrocardiogram was observed in the rats to analyze the ST-segment deviation and cardiac arrhythmia score. The expression of c-fos protein in FN and LHA was detected by immunohistochemistry method. Results: Compared with the sham operation group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in the FN and LHA increased significantly in the model group (all P<0.05). Compared with the model group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in FN and LHA decreased significantly in the EA-Heart Meridian group (all P<0.05). Compared with the EA-Heart Meridian group, the ST-segment deviation and cardiac arrhythmia score increased significantly in the EA-Lung Meridian group, LHA+EA-Heart Meridian group and FN+EA-Heart Meridian group (all P<0.05); the expression of c-fos in FN increased significantly in the EA-Lung Meridian group and LHA+EA-Heart Meridian group (both P<0.05); the expression of c-fos in LHA increased significantly in the EA-Lung Meridian group and FN+EA-Heart Meridian group (both P<0.05). Conclusion: FN and LHA are involved in the mechanism of EA at Heart Meridian to improve the acute MIRI reactions, and the cerebellum may participate in the improvement of cardiac function by EA through the cerebellum-hypothalamus projection.

Objective To investigate the effects of melatonin (MT) on rats with acute paraquat (PQ) poisoning. Method Fifty-four Sprague-Dawley (SD) rats were randomly divided into three groups (each group 18 rats) and given the following treatment: intragastric injection of PQ at 50 mg/kg (PQ); intragastric injection of paraquat followed by intraperitoneal injection of MT at 10mg/kg once a day (MT); intragastric injection of normal saline (Control). Serum assays for malondialdehyde (MDA) levels and superoxide dismutase (SOD) and glu tathione peroxidase (GSH-Px) activities were determined on the 1st, 3rd and 7th day post treatment. Clinical manifestations of poisoning and pathological changes in the lungs were also observed. Results Serum MDA levels were significantly increased (P ＜ 0.01), and SOD and GSH-Px activities significantly decreased (P ＜ 0.05) in the PQ group compared to the control group. Serum MDA levels were significantly decreased, and serum SOD and GSH-Px activities increased in MT group compared to the PQ group (P ＜ 0.05). Clinical manifestations of intoxication and pathological lung changes were also ameliorated in poisoned rats treated with MT. Condutions Administration of MT alleviates clinical manifestations of acute paraquat poisoning in rats by Limiting the damage from lipid peroxidation.
