Objective To evaluate the effect of intercostal nerve cryoanalgesia for post-thoracotomy pain control and the chronic discomfort of the incision.Methods A prospective analysis was carried out in 200 patients after standard posterolateral thoracotomy.Then the patients were randomly divided into five groups after gender stratification,each group with 40 patients.Group A was the control group,which was received no advanced method to prevent the pain after operation,only with Pethidine injected while patient require.Group B was PCIA group.Group C was PCEA group.Group D was cryoanalgesia group.Group E was cryoanalgesia and PCEA group.VAS score was used in the consecutive 7 days after operation.And we recorded the doses of pethidine injected in the 7 days,as well as the complications and the side effects.On the third and sixth month,patients were followed up by telephone or clinic review for their pain control and discomfort of the incision.Results The VAS score and the average doses of using Pethidine were lower in group D and group E than that in other groups.Group D had a lower ratio of nausea,vomiting,pruritus and lethargy than any other group.Group A,group D and group E had a higher ratio of pain of incision and other adverse reactions than group B and group C.Conclusion Intercostal nerve cryoanalgesia could effectively relief the postoperative pain,reduce the ratio of traumatic stress reaction and side effect.Cryoanalgesia may be a factor that could add the chronic discomfort of the incision.

Objective: To study the relationship between dilated cardiomyopathy and nuclear lamina protein (LMNA) gene mutation in Kazak ethnics at Xinjiang area.
Methods: A Kazak familial dilated cardiomyopathy (FDCM) with 31 members was studied. In addition, 160 patients with idiopathic dilated cardiomyopathy (IDCM) with 160 healthy controls were enrolled in our study, and they were divided into 4 groups: IDCM-Kazak, IDCM-Han and Control-Kazak, Control-Han.n=80 in each group. Peripheral blood DNA were extracted, 12 exons with nearby introns of LMNA gene were detected by PCR and the ampliifed products were sequenced and compared with the standard template of CHROMAS and BLAST software to identify mutation sites. LMNA mutation in both Kazak and Han IDCM patients were investigated.
Results: A novel LMNA mutation (insC, CGG→CCG) at exon 7 was identiifed in a FDCM proband, it caused an amino acid substitution as Arg to Pro, and a known LMNA polymorphism loci rs4641 (c.1362C>T His454His) was fund at exon 10. In addition, LMNA polymorphism loci rs4641 genotype distribution (χ2=5.16,P=0.036) and allele frequency (χ2=4.50,P=0.034) were statistically different between IDCM-Kazak group and Control-Kazak group; while such differences were no statistic meaning between IDCM-Han group and Control-Han group. Logistic regression analysis indicated that LMNA polymorphism loci rs4641 was related to IDCM occurrence in Kazak ethnics (P=0.025, OR=0.412, 95% CI 0.189-0.896).
Conclusion: LMNA polymorphism loci rs4641 was related to IDCM in Kazak ethnics at Xinjiang area, which might be susceptible loci for IDCM occurrence.

Objective To review the effect of exposed and buried Kirschner wire fixation of lateral humeral condyle fracture in children.Methods Randomized control trials (RCTs) about exposed versus buried Kirschner wire fixation of lateral humeral condyle fracture in children were identified through electronic search using the Cochrane Collaboration search strategies and manual search.Electronic database included Cochrane Library,Medline,PubMed,CBM,VIP,CNKI,Wanfang database and other Chinese and English database.Manual research included related journals and conference proceedings.Quality analysis of the included literatures was performed using the methodological index for non-randomized studies (MINORS).RevMan 5.3 software was used for Meta analysis.Results Four studies involving exposed Kirschner in 150 cases and buried Kirschner in 351 cases were included.The two techniques were similar with respect to postoperative infection (OR =1.10,95％ CI 0.52 ～ 2.33,P ＞ 0.05),superficial infection (OR =1.45,95 ％ CI 0.66 ～ 3.18,P ＞ 0.05),reoperation rate (OR =2.29,95％CI 0.51 ～ 10.25,P ＞0.05),delayed union rate (OR =1.57,95％ CI 0.76 ～ 3.21,P ＞0.05) and total complications (OR =1.57,95％ CI 0.76 ～ 3.21,P ＞ 0.05).However,Kirschner wire exposure shortened the time of pulling out Kirschner wire (MD =-13.28,95％ CI-16.42 ～-10.14,P ＜0.05).Conclusion Applied for lateral humeral condyle fracture in children,exposed versus buried Kirschner wire fixation results in short Kirschner wire stabilization time that avoids local anesthetic and cost while pulling out Kirschner wire in the late stage.

Objective: To observe the clinical characteristics and current treatment status in patients with chronic heart failure (CHF) at different grade hospitals in Xinjiang Area.
Methods: A total of 5357 patients with CHF diagnosis discharged from 20 different grade hospitals in Xinjiang area from 2011-01 to 2012-02 were enrolled. The age, gender, nationality, etiology of CHF, cardiac function, complications and current medication status in all patients were systemically studied.
Results:①There were 2295/5357 (42.8%) patients with Han nationality, 2255 (42.1%) with Uyghur nationality and 8.07 (15.1%) with other nationalities. The average age of patients was at (64.60 ± 12.77) years.②The etiology of CHF were, in turn, as: coronary artery disease (CAD) 50.8%, hypertension (31.8%), dilated cardiomyopathy (7.2%).③ The ratios of patients with NYHA III-IV in county hospital 440/682 (64.5%), in regional hospital 1180/1557 (75.8%) were higher than that that in grade A class 3 hospital 967/3118 (31.0%), ( =1390.362,P=0.000).④The patients in county hospital, regional hospital showed increased left atrial diameter (44.7 ± 8.8) mm, (39.5 ± 8.1) mm and left ventricular end-diastolic diameter (60.6 ± 11.1) mm, (56.9 ± 11.1) mm than those in grade A class 3 hospital (37.3 ± 7.1) mm and (53.8 ± 9.7) mm; while decreased LVEF (41.9 ± 10.5) %, (42.3 ± 13.0) % than that in grade A class 3 hospital (46.5 ± 12.8), allP<0.001.⑤The medication status in different grade hospitals as ACEI/ARB, β-blocker, aldosterone antagonist, diuretics, digitalis were at 72.8%, 66.8%, 46.6% , 45.5% and 26.8% respectively. The application of ACEI/ARB and β-blocker in county hospital (61.4% and 51.5%) and in regional hospital (72.3% and 58.3%) were lower than those in grade A class 3 hospital (75.6% and 74.3%); while the application of aldosterone antagonist in county hospitals (57.9%) and in regional hospital (73.8%) were higher than that in grade A class 3 hospital (30.6%), allP<0.001.
Conclusion: The etiology of CHF were mainly as CAD and hypertension in Xinjiang area, the patients in county and regional hospitals had more severe conditions than that in grade A class 3 hospital, which implying the distance between the guideline standard and real practice especially in basic level hospitals.

Objective Folate receptors ( FRs) , overexpressed on the surface of a variety of tumor cells , are potential targets for tumor targeting therapy .This study aimed to prepare an FR-mediated drug nanocarrier with folate conjugated pullulan acetate ( FPA) to target chemotherapeutic agents to FR-overexpressed tumor cells and investigate its tumor-suppressing effect in vitro. Methods The cytotoxicity of epirubicin-loaded FPA nanoparticles ( FPA/EPI NP) against HepG2 and Hela cells was evaluated by MTS assay.The HepG2 and Hela cells were divided into five groups to be treated with NPs (NP control), chlorpromazine, chloro-quine, amiloride, and folate, respectively, followed by detection of the fluorescence intensity by flow cytometry . Results FPA/EPI NP was successfully formulated into NPs , with the mean particle size of (268.5 ±12.0) nm, by dialysis with an almost spherical shape . The drug-loading rate and entrapment rate of FPA/EPI NP were (6.45 ±1.04) and (72.45 ±11.50) %, respectively.The survival rates of the HepG2 and Hela cells were both >95%after 24 hours of incubation with FPA NP at 5, 40, 200, 400 and 1000μg/mL and 90.0%after 72 hours.The survival rates of the HepG2 cells treated with 5, 40, 200, 400 and 1000μg/mL FPA/EPI NP for 24 hours were (92.3 ±5.2), (70.4 ±4.6), (50.0 ±4.0), (41.1 ±4.1) and (27.0 ±3.6) %, respectively.Compared with the NP control group, the Hela cells of the chlorpromazine , amiloride and folate groups showed a significantly lower rate of NP uptake (P<0.05), and so did the HepG2 cells pretreated with chlorpromazine or amilo-ride (P<0.05).At 72 hours, the half maximal inhibitory concentrations (IC50) of FPA/EPI NP against HepG2 and Hela cells were 168 and 105μg/mL, respectively . Conclusion Clathrin-mediated endocytosis and macropinocytosis are involved in the internaliza-tion of FPA/EPI NP in HepG2 cells, while clathrin-and FR-mediated endocytosis in that of Hela cells .FPA NP may serve as a new drug carrier for tumor-targeted therapy .

Objective To evaluate the effects of hyperbaric oxygen (HBO) combined with drug therapy on patients with delayed encephalopathy caused by carbon monoxide poisoning ( COP). Methods Twenty to forty sessions of HBO therapy were used to treat 34 COP patients. Assessment relied on 99mTc-ethyl cysteinate dimer (~(99m)Tc-ECD) single photon emission computed tomography (SPECT) imaging of cerebral perfusion before and after treatment. Results After HBO therapy, cerebral perfusion in the COP patients improved significantly. There was a significant difference of the SPECT images before and after treatment. Conclusions SPECT imaging of cerebral perfusion can play an important role in the diagnosis of delayed encephalopathy caused by carbon monoxide poisoning, and it can be used for the therapeutic surveillance of HBO treatment.

Objective To analyze the pathological and clinical characteristics of patients with idiopathic IgA nephropathy accompanied by vasculitic/crescentic lesion (IgA-V/C). Methods Data of 222 patients diagnosed as idiopathic IgA nephropathy by renal biopsy, among them 87 cases with vasculitic/crescenlic (V/C)lesion, from our department in 2004 were analyzed retrospectively. Clinical and pathological data from patients with IgA-V/C were compared to those of non-IgA-V/C patients and of lupus nephritis (LN) patients with V/C lesion. Results Vasculitic/crescentic lesion was found in 39.19% (87/222) patients with idiopathic IgA nephropathy.And about( 14.08?12.75)% of the glomeruli was affected. It should be taken into account that there was no significant differences of clinical manifestations including blood pressure, urinary protein excretion between IgA-V/C group and non-IgA-V/C group .except serum creatinine(Scr)level which was significantly higher in IgA-V/C group. In addition, only 37.9% of IgA-V/C patients presented high Scr level,thus the lesion of V/C in idiopathic IgA nephropathy was easily overlooked. Patients with idiopathic IgA nephropathy were found to have higher percentage of glomerular sclerosis (64.86% vs 40.00%) and ratio of sclerostic glomeruli to total glomeruli [ (26.98 ?24.68)% vs (16.10 ?18.80)% ]as compared to LN group, which further predicated the progressing characteristics of IgA nephropathy. Conclusions Vasculitic/crescentic lesion is a quite common finding in idiopathic IgA nephropathy and often associated with no dramatically symptoms. It is possible for vasculitic/crescentic lesion to induce unmarked lose of nephron slowly and continually, so as to accelerate IgA nephropathy progression to end-stage renal failure.

This paper aimed to study phenylpropanoids of Tripterygium hypoglaucum. Twenty-four compounds were isolated from the 70% EtOH extracts of T. hypoglaucum by silica gel column chromatography, reversed phase column chromatography, gel column chromatography, preparative thin layer chromatography, and semi-preparative high performance liquid chromatography. Compounds 1-3 were three new phenylpropionds.

Compounds 4-6, 9, 14, 15, 18, 19, and 21-24 were obtained from Tripterygium genus for the first time. The cytotoxicity assay of cancer cells suggested that compound 20 displayed cytotoxicity on the breast cancer 4T1 cells whose 50% inhibitory concentration was 125.60 μmol·L^-1.

Objective To observe the therapeutic effect ofbotulinum toxin type A (BTX-A) on spasticity of the upper extremity after stroke. Methods Fifty-four patients with upper extremity spasticity after stroke were randomly divided into treatment group and control group. The patients in treatment group were treated with BTX-A and rehabilitation training, while those in control group only with rehabilitation training. The efficacy was assessed with Modified Ashwonh Scale, Fugi-Meyer Assessment and Bartbel index before and 2, 4 and 12 weeks after treatment. Results The Ashworth scale score in treatment group was reduced significantly as compared with that in control group after 2- and 4-week treatment (P<0.01). And there was significant difference in FugI-Meyer Assessment and Barthel index between treatment group and control group after 4- and 12-week treatment (P<0.01). Conclusion The local injection of BTX-A for the muscle spasticity after stroke is effective and safe, and its combination with rehabilitation training can improve rapidly Fugl-Meyer scores and activities of daily living of patients.
