Objective To observe the effects of marzulene(L-glutamine and sodium gualenate)on cellular immune function in patients with severe acute pancreatitis(SAP). Methods A prospective study method was conducted in which 80 patients with SAP were divided into trial group and control group(each 40 cases)according to the table of random number methods,and in the mean time 20 healthy volunteers were enrolled in the healthy control group. Both SAP groups received standard total parenteral nutrition(TPN)with same quantities of heat and nitrogen, and the trial group additionally accepted intravenous drip of marzulene 0.4 g?kg-1?d-1(once a day)for 7 days,while the control group received the same amount of normal saline intravenous drip for 7 days. One day before treatment and on the 7th day after treatment,the peripheral venous blood samples were collected. The T-lymphocyte proliferation activity was tested by methyl thiazolyl tetrazolium(MTT)assay,and the interleukin-2(IL-2)and interleukin-6(IL-6) secretion levels were detected by enzyme-linked immunosorbent assay(ELISA). Results Compared to the healthy control group,the levels of T lymphocyte proliferation activity〔absorbance(A)value〕and IL-2(ng/L)were markedly decreased and IL-6(ng/L)secretion level was obviously increased before treatment in the two SAP groups(P<0.05 or P<0.01). Compared to prior treatment,the levels of T lymphocyte proliferation activity and IL-2 were significantly increased after 7 days of treatment in the trial group(both P<0.05),and basically restored to normal levels,while in the control group they were progressively decreased(both P<0.05),the levels in trial group being significantly higher than those of the control group(T lymphocyte proliferation activity:1.08±0.27 vs. 0.43±0.25,IL-2:16.5±1.4 vs. 9.4±2.9,both P<0.05),but compared to prior treatment,the level of IL-6 was significantly decreased in the two SAP groups(both P<0.05),the level of IL-6 in control group was recovered to the level of healthy control group,and the level in trial group being significantly lower than that of the control group(18.8±4.5 vs. 22.3±3.1, P<0.05). Conclusions The patients with SAP have cellular immune dysfunction,the manifestations being the suppression of T lymphocyte proliferation and IL-2 and increase of IL-6 release. Early application of marzulene can help to improve the immune function of lymphocytes in patients with SAP.

With the Meta-analysis method, the clinical efficacy of acupuncture and other regular methods for aphasia was evaluated, and the acupoints selection for aphasia was explored. The acupuncture literature of clinical randomized control trials for aphasia published in CNKI, WANFANG, VIP and CBM database was searched; the statistical analysis of clinical efficacy of acupuncture and other regular methods for aphasia was performed by using software Revman 5. 2 provided by Cochrane library. A file of Microsoft Excel was established to perform the analysis of acupoints selection based on frequency analysis method, so as to summarize the characteristics and rules. Totally 385 articles were searched, and 37 articles those met the inclusive criteria was included, involving 1,260 patients in the acupuncture group and 1 238 patients in the control group. The Meta-analysis results showed OR = 3.82, 95% Cl [3.01, 4.85]; rhombus was located on the right side and the funnel plot was nearly symmetry, indicating the treatment effect of the acupuncture group for aphasia was superior to the control group (Z = 11.04, P < 0.000 01). The frequency-analysis results showed that the frequency of acupoints from top to bottom was Lian-quan (CV 23), Tongli (HT 5), Yamen (GV 15), Jinjin (EX-HN 12), Yuye (EX-HN 13), Baihui (GV 20), Yuyan II, Yuyan I and Yuyan III. The frequency of meridians from top to bottom was the governor vessel, extra channels, conception vessel, heart meridian and large intestine meridian. It is concluded that the clinical efficacy of acupuncture combined with speech rehabilitation training and medication treatment for aphasia is superior to that of speech rehabilitation training and medication treatment alone. The clinical treatment for aphasia focuses on its local effect; the main acupoints are in the head and face, and the meridians are governor vessel, extra channels and conception vessel.

Objective To discuss the clinical value of CT combined electronic level guided percutaneous transthoracic needle biopsy in diagnosis of small pulmonary nodules.Methods 44 cases of lung mini-nodule underwent CT combined electronic level guided percutaneous transthoracic needle biopsy.After operation the tissue was sent for pathologic examination.The nodules were divided into two groups,including Group A (diameter 0.5-1.0 cm,N=10) and Group B (diameter 1.1-2.0 cm,N=34),according to the different sizes of diameter.The excision of postoperative pathological and diagnosis result of clinical diagnosis and treatment of more than 12 months follow up were taken as the final result.The sensitivity,specificity,veracity and complications were compared and analyzed using paired x2 test,taking P＜0.05 as significant difference.Results (1)The arrival rate of target puncture were 100 ％ in 44 cases,with the sensitivity rate of 90.9％,specificity rate of 100 ％,veracity rate of 88.6 ％,positive predictive value of 97.5 ％,and negative predictive value of 100 ％.The sensitivity,specificity and veracity of Group A were 77.8％,100％ and 70.0％ respectively.And the sensitivity,specificity and veracity of Group B were 94.1％,100％ and 94.1％ respectively.The sensitivity,veracity of Group A was higher than Group B (P＜0.05),while there was no difference in specificity.(2)Complication:the incidence rate of pneumothorax,pulmonary bleeding symptoms and hemothorax were 9.1％,11.4％,2.3％,respectively.The incidence rate of total complication was 22.7％,and all be cured after the treatment.The lesions with emphysema around is a risk factor for pneumothorax and pulmonary bleeding symptoms (x2 =11.2,10.2,P＜0.05).However,the position,size and deepness was not correlated with the complications mentioned above (P ＞0.05).Conclusion CT combined electronic level guided percutaneous transthoracic needle biopsy is a safe,effective and accurate diagnostic method for lung mini-nodule lesion.

Objective To explore the effect of comorbidities on the surgical outcomes of elderly patients with hip fracture. Methods The Age,gender,weight,type of fracture,preoperative comorbidities and surgical outcomes of 117 patients aged 80 yr or over who undergoing hip fracture surgery in our hospital were recorded. Patients were divided into rehabilitation group and postoperative in-hospital death group ac-cording to surgical outcomes. The potential predictors of postoperative in-hospital death were identified by univariate model and were then entered into multiple Logistic regression analysis. Results Twenty three patients(19. 7%)had no comorbidity,94 patients(80. 3%)had one or more comorbidities. Ten patients(8. 5%)died in hospital after the operation. Predictors of postoperative in-hospital death were preoperative respiratory diseases and three or more comorbidities. Conclusion Surgical outcomes of elderly patients with hip fracture may be predicted by analysing preoperative comorbidities. Preoperative preparations must be sufficient in order to ensure successful operation.

Objective To investigate the expression of nucleotide-binding oligomerization domain protein 2 (NOD2)in serum of patients with hepatocellular carcinoma (HCC),and to analyse the roles of NOD2 in HCC development and its clinical diagnostic value.Methods This study including 66 patients with HCC in the hospi-tal from March 1,2013 to December 31,2014 and 61 healthy controls.Serum NOD2 levels were determined by enzyme-linked immunosorbent assay (ELISA).Analysis of significance was performed with rank sum test using SPSS statistical 16.0 software.Results Serum levels of NOD2 in HCC patients were 171 pg/ml,significantly higher than that of healthy controls(95 pg/ml,Z =-5.00,P =0.00),and the serum NOD2 levels were correla-ted with clinical stage of HCC (H=56.26,P =0.00).Compared with the serum NOD2 levels in stageⅠ,Ⅱpatients (106 pg/ml)and healthy controls (95 pg/ml),the serum NOD2 level in stage Ⅲ and Ⅳ (220 pg/ml) were significantly increased (χ2 =31.24,P =0.00;χ2 =47.23,P =0.00),but the expression of NOD2 in stageⅠandⅡwere nearly equal to that of the healthy controls (χ2 =0.36,P =0.83).The ROC analysis revealed that the best diagnostic cutoff-point of serum NOD2 levels for predicting the Ⅲ and Ⅳ stages of HCC was 148.78 pg/ml,meanwhile corresponding sensitivity was 89.1% and specificity was 77.0%.Additionally,corre-lation analysis demonstrated that there was no significant correlation between NOD2 and alpha-fetal protein (r =0.44,P =0.14).Survival curves obtained that the survival time of HCC patients with NOD2 serum concentrations≥ 200 pg/ml was significantly less than that <200 pg/ml (χ2 =15.32,P <0.05).Conclusion NOD2 is highly expressed in the serum of HCC patients,especially in advanced patients,which is possibly involved in the development of HCC and has the potential to become an effective marker used for HCC diagnosis.

Objective To investigate the combined effect and mechanism of metformin (Met) and 2-deoxy-D-glucose (2DG) on cell proliferation and apoptosis in liver cancer cells HepG2 and Hep3B.Methods Wst-1 reagent was used to determine the anti-proliferation effects after treatments with Met and 2DG alone or combined in HepG2 and Hep3B cells.Microscopy was used to observe cell morphological changes after treatments with Met and 2DG alone or combined in HepG2 and Hep3B cells.Cell apoptosis was observed by flow cytometry after treatment of different kinds of drugs.Western blotting was used to analyze the protein expressions of Caspase-3,PARP,Mcl-1 of HepG2.Results The survival rate of HepG2 cells in the combination group was (22.48 ± 0.51)％,and compared with the control group (100.00 ± 5.05)％,Met group (80.68 ±5.10)％ and 2DG group (72.56 ±4.34)％,the differences were statistically significant (P ＜ 0.001;P ＜ 0.001;P =0.001).The survival rate of Hep3B cells in the combination group was (29.16 ± 1.34) ％,and compared with the control group (100.00 ± 1.23) ％,Met group (59.58 ± 1.92) ％ and 2DG group (33.87 ± 1.95) ％,the differences were statistically significant (P ＜ 0.001;P ＜ 0.001;P =0.001).Microscopy observation showed that combined treatment of Met and 2DG caused less viable adherent cells of HepG2,but more floating dead cells.While the combination group also caused a decrease in the density of Hep3B cells,but did not significantly increase the shedding of cells.The apoptosis of HepG2 cells in the combination group was (39.63 ± 0.21) ％,and compared with the control group (7.12 ± 0.14) ％,Met group (12.56 ± 0.35) ％ and 2DG group (15.16 ± 1.93) ％,the differences were statistically significant (P ＜0.001;P ＜ 0.001;P =0.001).The apoptosis of Hep3B cells in the combination group was (12.58 ± 1.03) ％,and compared with the control group (2.82 ± 0.51) ％ and Met group (8.98 ± 0.86) ％,the differences were statistically significant (P ＜ 0.001;P =0.007),but compared with the 2DG group (12.40 ± 1.78) ％,the difference was not statistically significant (P =1.000).Furthermore,Western blotting demonstrated that the combined treatment induced evident Caspase-3 activation and poly ADP-ribose polymerase (PARP) cleavages,and decreased expression of Mcl-1.Conclusion The combination of Met and 2DG can effectively inhibit cell proliferation of HepG2 and Hep3B,and induce apoptosis of HepG2 cells.The mechanism may be involved with Caspase-3 activation,cutting PARP substrate and decreasing Mcl-1 protein.
