Objective To investigate the changes of tumor necrosis factor- ?(TNF- ?) and souble intercellular adhesion molecule - 1 (sICAM - 1) in serum and cerebrospinal fluid (CSF) in children with viral encephalitis (VE) before and after treatment,and to explore the pathogenesis of the cytokins in VE. Methods The levels of TNF - ? and sICAM - 1 in serum and CSF were determined before and after treatment using EL1SA in 38 children who were admitted with VE, and 20 children as normal controls. Results The levels of TNF- ? and sICAM - 1 in serum and CSF before treatment were obviously higher than those of control group,and the difference was significant(P 0. 05), but the serum and CSF TNF - ? and sICAM - 1 levels in SVE group were higher than those of control group(P

Objective To study the percutaneous permeability through mouse skin of lidocaine hydrochloride-loaded destran-based niosomes(LID-HLD-BNs)in vitro and in vivo. Methods HPLC was employed to exam lidocaine hydrochlo?ride. Lidocaine hydro-chloride-loaded conventional liposomes (LID-CLs) and lidocaine hydrochloride injection (LID-IJ) were used as control. Isolated mouse skin was added into Franz diffusion cell to evaluate the permeability of LID-HLD-BNs in vitro. Confocal Laser Scanning Microscopy(CLSM)was used to observe the permeation depth of mouse skin in vivo. Re?sults The permeation rate and cumulative permeation amount were significantly higher in LID-HLD-BNs group than those of LID-CLs and LID-IJ groups (P<0.05). CLSM studies also confirmed that HLD-BNs reached deeper layers of the skin. Conclusion LID-HLD-BNs has good transdermal ability.

OBJECTIVETo explore the therapeutic effect of qi benefiting blood activating method (QB-BAM) on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients with blood stasis syndrome (BSS) by observing its effect on plasma fibrinogen (Fg) and D-dimer (D-D) levels.

METHODSSixty AECOPD patients with BSS were randomly assigned to the treated group and the control group, 30 in each group. All patients received conventional therapy for AECOPD. Those in the treated group were additionally injected with Shengmai Injection and Tanshinone IIA Injection. Clinical efficacy and indices including levels of Fg, D-D, PaO2, and PaCO2 were measured and compared before and after treatment.

RESULTSThe effective rate was 93.3% (28/30 cases) in the treated group, higher than that of the control group [73.3% (22/30 cases) , P < 0.05]. There was no significant difference in all indices between the treated group and the control group before treatment (P >0.05). After treatment all indices were significantly improved in the two groups (P < 0.01). But in the treated group levels of Fg and D-D decreased more and levels of PaO2 increased more (P < 0.01). Plasma levels of Fg and D-D levels were negatively correlated with PaO2 (r = -0.493, r = -0.438, P < 0.01) before treatment, and also negatively correlated with PaO2 (r = -0.452, r = -0.325, P < 0.01, P < 0.05) after treatment, but they were not significantly correlated with PaCO2 before and after treatment (P >0.05).

CONCLUSIONSQBBAM could play a therapeutic role in improving prethrombotic states of AECOPD patients with BSS. Plasma levels of Fg and D-D were related to the severity of AECOPD.

Adefovir dipivoxil is commonly used for treatment of chronic hepatitis B. The renal toxicity of adefovir dipivoxil is dose- and time-related, occurring often in patients with a daily dose over 30 mg and those with impaired renal function. We report a case of chronic hepatitis B with a history of taking adefovir dipivoxil at 10 mg/day for 4 years. The patient complained of lumbosacral and joint pain and had the diagnosis of ankylosing spondylitis (AS) or spondyloarthropathy in several hospitals before admission in our hospital. A diagnosis of acquired Fanconi syndrome and hypophosphatemia osteomalacia associated with progressive muscular weakness was made eventually. We reviewed the literature and found reports of only fewer than 10 similar cases. Clinical attention should be given to kidney damage induced by adefovir dipivoxil.

OBJECTIVETo evaluate the pancreatic fistula affected by different type of pancreaticojejunostomy after pancreaticoduodenectomy.

METHODSElectronic databases PubMed, EMBase, COCHRANE Library, Wanfang, and VIP etc were used to search for randomized controlled trials or non randomized prospective controlled trials reported before September 2013 on clinical effects of pancreaticojejunostomy after pancreaticoduodenectomy. The statistical analysis was done by Review Manager 5.0.

RESULTSA total of 8 trials were included in this meta-analysis. The effects of duct-to-mucosa pancreaticojejunostomy (dmPJ) and invaginating pancreaticojejunostomy (iPJ) on postoperative complication in five studies were compared, and no statistical significance were found in postoperative pancreatic fistula (POPF) (M-H:OR = 0.77, 95% CI:0.35-1.69, P = 0.52), reoperation (M-H:OR = 1.38, 95% CI:0.64-2.95, P = 0.41) and mortality (M-H:OR = 1.15, 95% CI:0.42-3.13, P = 0.79) between dmPJ and iPJ. The effects of binding pancreaticojejunostomy (bPJ) and conventional pancreaticojejunostomy (cPJ) (including duct-to-mucosa pancreaticojejunostomy and invaginating pancreaticojejunostomy) on postoperative complication were compared, and no statistical significance were found in postoperative pancreatic fistula (POPF) (M-H:OR = 0.57, 95% CI = 0.28-1.17, P = 0.13) , reoperation (M-H:OR = 1.18, 95% CI = 0.48-2.92, P = 0.72) and mortality (M-H:OR = 0.74, 95% CI = 0.27-1.99, P = 0.55) between bPJ and cPJ.

CONCLUSIONThere are no significant differences between dmPJ and iPJ in pancreatic fistula reoperation and mortality, and there are also no significant differences between bPJ and cPJ.

OBJECTIVETo investigate the clinicopathological characteristics, surgical treatment and prognosis of gastrointestinal stromal tumors(GIST).

METHODSThe clinicopathological data of 84 patients with GIST undergone resection between April 1997 and June 2008 were analyzed retrospectively, and the prognosis was evaluated.

RESULTSOut of 84 cases, 42 tumors located in stomach, 24 in small intestine, 18 in other sites. Tumor sizes ranged from 0.5 to 25 cm(average 5.6 cm). Positive rate of CD117 expression determined by immunohistochemical methods was 96.4%. Seventy-nine cases underwent complete tumor resection, while 5 cases received palliative resection or biopsy. Seventy-eight patients were followed up and their 1-, 3-, 5-year survival rates were 92.0%, 79.2%, 72.0% respectively. The Fletcher's classification of malignancy risk groups for GIST was related to the survival rates(P=0.001). The differences of survival rate among very low risk group, low risk group and high-risk group were significant(P=0.003, P=0.000).

CONCLUSIONSComplete tumor resection in the initial operation of GIST should be emphasized. The Fletcher's classification of malignancy risk groups for GIST is related to the survival rate. Extended surgical resection is required for GIST of higher malignancy risk.

OBJECTIVETo investigate the influence of mechanical stretch on the expression of myosin heavy chain (MHC) mRNA in cardiomyocyte subjected to ischemia and hypoxia.

METHODSMechanical stretch model of in vitro cultured cardiomyocyte was established for the study. The cells were processed by non-sugar hypoxic stimuli to simulate postburn ischemic and/or hypoxic injuries. The cells were then divided into normal control (N), 10% stretch (S), ischemic and hypoxic culture (IHC), 10% stretch with ischemia and hypoxia (SIHC) groups. The changes in MHC mRNA expression were observed at 1, 3, 6 and 12 post treatment hours (PTHs) by RT-PCR and were statistically analyzed with gel image analysis software.

RESULTSThe expression of both alpha and beta MHC mRNA increased in 10% stretch group, especially of beta MHC mRNA (P < 0.01). The transformation of alpha MHC mRNA to beta MHC mRNA was accelerated in IHC group, and alpha MHC mRNA expression was decreased at 12 PTH. The expression of beta MHC mRNA was increased after ischemia and hypoxia, peaked at 6 PTH, and decreased thereafter (P < 0.05). The transformation of alpha MHC mRNA to beta MHC mRNA was more obvious in SIHC group, and which was intensified along with the elapse of stimulation time. The expression of both alpha and beta MHC mRNA were down-regulated at 12 PTH (P < 0.05).

CONCLUSIONDown regulation of MHC mRNA expression by ischemia and hypoxia could be aggravated by mechanical stretch, indicating that mechanical stretch might be a possible cause for cardiac dysfunction.

OBJECTIVETo observe the serum and placental levels of FAS and FASL in preeclampsia (PE) and to study its relationship with the disease.

METHODSForty women with preeclampsia and 39 healthy pregnant women were recruited and samples of serum and placentas were collected. The expression of Fas and FasL in placentas was detected with Western blot and the concentration of soluble Fas and FasL in serum was detected with ELISA method.

RESULTSerum levels of soluble Fas in PE group were significantly higher than those of healthy pregnant women (2.11+/-0.95 mg/L compared with 1.57+/-0.60 mg/L, P<0.05), and serum levels of soluble FasL in PE group were also significantly higher than those in controls (4.43+/-1.90 g/L compared with 3.48+/-1.53 g/L, P<0.01). There were no significant differences in Fas and FasL levels in placentas between PE group and healthy pregnant women (P>0.05 for both).

CONCLUSIONThe elevated serum Fas and FasL levels are closely associated with preeclampsia, which may play an important role in the pathogenesis of the disease.

OBJECTIVETo explore the role of macrophage colony-stimulating factor (MCSF) in the pathogenesis of preeclampsia.

METHODSBy ELISA method, MCSF concentrations were determined in serum samples obtained from 39 patients with preeclampsia and 40 normal pregnant women as controls. The concentrations of serum MCSF were compared between preeclampsia and normal pregnancy, and between early-onset and late-onset preeclampsia.

RESULTSerum MCSF concentrations were significantly higher in preeclamptic women than those in controls (431.0 kIU compared with 179.1 kIU, P<0.001). There were no significant differences in serum MCSF levels between early-onset and late-onset preeclampsia (P>0.05). Serum MCSF was not correlated with maternal age, gestational age, and placenta weight (P>0.05 for all).

CONCLUSIONIncreased level of serum MCSF is an important indicator of preeclampsia and it may play a role in the pathogenesis of the disease.

OBJECTIVETo observe the distribution features of tender points in knee of patients with knee osteoarthritis in order to provide evidences for the treatment and diagnosis.

METHODSFrom November 2011 to December 2012,86 patients with knee osteoarthritis were recruited, including 21 males and 65 females, ranging in age from 45 to 85 years old, with an average of (59.98 +/- 8.23) years old. The course of disease ranged from 3 months to 15 years. The tender points and its distributions were determined by finger press carefully on their knees. Data of studying was analyzed by frequency statistics and Hierachical cluster analysis.

RESULTSThe distribution of tender points in the knee osteoarthritis was mainly in the interior region and anterior area such as in apex of patella, adductor tubercle and et al. According to the results of hierachical cluster analysis, the tender points could be divided into two categories the first cluster was in the interior region of knee, the second cluster was in the lateral region.

CONCLUSIONThe findings demonstrated that cluster analysis statistical method can be used for classification of the distribution of tender points. The distribution features of tender points in knee osteoarthritis are related to the anatomic site in knee.
