Objective To explore the relationship between the level of high-sensitivity C-reactive protein (hs-CRP),CRP 1059G/C gene polymorphism and cerebral infarction(CI).Methods The CRP 1059G/C genotype and allele frequencies were assayed by polymerase chain reaction-restricted fragments length polymorphism (PCR-RFLP) in 105 patients with CI and 121 controls.The level of serum hs-CRP was detected by immune-turbidimetry.The relationship between the condition of CI patients,the level of serum hs-CRP and CRP 1059G/C genotype and allele frequencies were anaysed.Results Compared to the control group,the CRP 1059G/G genotype and G allele frequencies in CI group were statistically higher,G/C+C/C genotypes and C allele frequencies were statistically lower(all P

Objective To investigate the sedative effects of different doses of dexmedetomidine with mid-azolam in spinal anesthesia. Methods 130 cases of spinal anesthesia were randomly divided into 2 groups,group D1 and group D2,with 65 cases in each group. Patients in 2 groups were given midazolam and dexmedetomidine with different doses. The heart rates ,blood pressure ,SpO2 ,Narcotrend value and Ramsay sedation scores were recorded at mutiple time points. The working time ,maintaining time of sedative effect ,and adverse reactions were compared between 2 groups. Results MAP,HR and NT decreased significantly in 2 groups(P < 0.05,respec-tively). The keeping time was relatively longer in group D1 compared with group D2(P<0.05). The working time was faster in group D2 compared with group D1. The rate of bradycardia in group D2 was relatively higher than that in group D1. Conclusion Good sedative effect can be obtained by drug in 2 groups. Group D1,with midazolam 0.05 mg/kg+dexmedetomidine 0.3μg/kg,may have a certain advantage in anaesthesia in the spinal canal.

ObjectiveTo observe the effect of early partial body weight support on walking ability for stroke patients with hemiplegia.Methods60 stroke patients were divided into 3 groups, receiving conventional early rehabilitation: group A (20 cases) received conventional rehabilitation for 8 weeks; group B (20 cases) received 2 weeks conventional rehabilitaion and 6 weeks partial body weight support; group C (20 cases) received 5 weeks conventional rehabilitaion and 3 weeks partial body weight support. Fugl-Meyer Assessment(FMA), Barther Index(BI) and Berg Balance Scale(BBS) were used to assess the effect before and after treatment.ResultsThe socres of FMA, BI and BBS improved in walking function after the treatment(P<0.05). Comparing with groups A and C, group B improved more significantly after treatment (P<0.05), and group C was better than group A (P<0.05). ConclusionPartial body weight support can improve walking function of hemiplegic patients at early stage.

Objective To evaluate the therapeutic effect of recombinant adeno-associated viral vector (rAAV) expressing human tissue kallikrein gene (rAAV-HK) on insulin resistance and renal complications in tyDe2 diabetic rats. Methods Male Wistar rats were injected low dose streptozotocin and fed with high fat and sucrose diets to form type 2 diabetic model. rAAV mediated HK gene (HK group) or LacZ gene (LacZ group) were introduced to the diabetic rats, and their systolic blood pressure, fasting blood glucose and insulin, serum creatinine, urine creatinine, urine osmolarity and urine microalbumin were measured. The homeostasis model assessment of insulin resistance (HOMA-IR), urinary albumin excretion rate (UAER) and creatinine clearance rate (Ccr) were calculated. The expression of PI3-kinase p11o catalytic subunit (p110) and Akt phosphorylation on Thr-308 were detected by Western blot. The morphology of kidney wag observed. Results Delivery of rAAVHK resulted in a reduction in blood pressure at 2 weeks and the hypotensive effect lasted for the duration of the study. The HOMA-IR was significantly lower in HK group than LacZ group (4.76±0.33 vs 8.36±0.48, P<0.01) at the end of the study, fasting insulin level was reduced [(8.19±2.45 vs 13.85±3.76)mIU/L. P<0.01], but there was no significant change in fasting blood glucose [(13.09±3.01 vs 13.58±2.88)mmol/L].The phosphorylation of p11o and Akt Thr-308 were significantly decreased in skeletal muscle and liver in LacZ group and were almost corrected by HK gene therapy. The UAER and Ccr were significantly lower and urinary osmolarity were higher in HK-treated rats compared with LaeZ rats. Histological assessment indicated that the renal complication was relieved by HK gene delivery. Conclusion The rAAV-mediated HK gene delivery efficiently attenuated insulin resistance partly through PI3K/Akt pathway and diabetic nephropathy in type 2diabetic rats.

Objective:To examine the feasibility of using cerebral state index(CSI)for monitoring the sedation depth during target-controlled infusion(TCI)with propofol and remifentanil.Methods:Forty-four consenting ASAⅠorⅡpatients(aged 18-60 years)undergoing elective surgery under general anesthesia were randomly divided into 4 groups(n=11 each)according to the target effect-site concentrations of remifentanil administered by TCI during induction of anesthesia.The target effect-site concentrations of remifentanil of R_0,R_2,R_4,and R_6 groups were 0,2 ng?ml~(-1),4 ng?ml~(-1),and 6 ng?ml~(-1),respectively. Anesthesia was induced by TCI with remifentanil and propofol.CSI and bispectral index(BIS)were used to measure the sedation depth.The initial effect-site propofol concentration(PCe)was 1.5?g?ml~(-1),which was increased by 0.5?g?ml~(-1) every 4 min.The modified OAA/S score(5=alert,1=does not respond to prodding),loss of eyelash reflex(LOR eyelash)and loss of response to electric tetanie stimulation(LOR tetanic)were compared against CSI,BIS and PCe(calculated effect-site propofol concentration).Correlation coefficients were calculated between CSI and other parameters.Results:The 4 groups were comparable with respect to the ages and bodyweights.CSI and BIS values were higher but PCe value were lower at LOR eyelash and LOR tetanic in R_2,R_4,and R_6 than those in the R_0 group(P

Glioblastoma is a malignant tumor in central nervous system, which has strong invasion, poor prognosis and short survival time. At present, the main treatment strategy of glioblastoma is surgical excision, supplemented by radiotherapy and chemotherapy. However, due to incomplete resection and high recurrence rate, it is urgent to find novel therapeutic method for glioblastoma. Photodynamic therapy, as a promising non-surgical treatment, provides a new strategy for postoperative adjuvant therapy of glioblastoma. This review summarizes the mechanism and clinical application of photodynamic therapy mediated by various photosensitizers in glioblastoma, in order to provide help for the treatment of glioblastoma.

OBJECTIVETo investigate the mothod and therapeutic efficacy of total hip anthroplasties (THA) for osteoarthritis secondary to Crowe type IV developmental dysplasia of hip in adults.

METHODSFrom May 2006 to December 2013, THA was performed on 15 adult patients (17 hips) with Growe type IV acetabular dysplasia, including 13 females and 2 males, with a mean age of 30.9 years old (22 to 58 years old) and an average preoperative Harris score of (34.0 ± 6.5) points. Traction of the affected limb was not performed before surgery. After extensive release and lengthening of soft tissues, sub-trochanteric osteotomy of the femur was performed, hip joint center was rebuilt and the abduction function was restored.

RESULTSThe patients were followed up with a mean period of 33 months (ranged from 6 months to 5 years). The postoperative Harris score was 85.0 ± 7.3,higher than the preoperative score. The extended length of limb ranged from 1.6 to 5.4 cm, with a mean of (3.42 ± 0.65) cm. The shortening and malformation of the affected limb were corrected in the most patients,with the difference in length of the two legs less than 1.5 cm. After surgery, 1 patient experienced partial sciatic nerve injury, which was largely recovered after 3 months of conservative treatment. One patient experienced complete sciatic nerve injury, which was partially recovered after 6 months of conservative treatment; a foot-drop varus deformity was formed in the distal end of the affected limb, which was improved after tendon transposition and transplantation. Joint pain was relieved, and the joint function was restored significantly. Over the follow-up period, no severe complications such as dislocation, infection, prosthesis loosening, or subsiding occurred.

CONCLUSIONSatisfactory efficacy can be achieved for adult Growe type IV acetabular dysplasia associated with osteoarthritis by THA, with proper soft tissue release and lengthening, sub-trochanteric osteotomy of femur, joint functional restoration, appropriate choice of prosthesis, and careful protection of nerves and vessels.

To provide accurate information on geographic distribution of crude drug Sailonggu in the plateau, we identified zokor species (Eospalax spp.) in Qinghai-Tibet Plateau using molecular methods. Based on the mitochondrial cytochrome B (cytb) gene sequences, we then extracted haplotypes from these sequences and reconstructed phylogenetic trees for the haplotypes using both maximum likelihood (ML) and Bayesian inference (BI) methods. Based on the trees, the species of each sample were determined. Five hundred and three samples from 35 populations were sequenced and their whole cytb sequences (1140 bp) were obtained. From these sequences 150 haplotypes were detected, in which, 126 were Eospalax baileyi, 20 were E. cansus, and 4 were E. smithi of the 35 populations, 28 were E. baileyi type, 5 were E. cansus type, and the remaining 2 were mixed of E. baileyi + E. cansus (DT2) and E. baileyi + E. smithi (ZN3). The results showed that, the regions around the Qinghai lake and near the upper stream of Yellow River started at Guide could be viewed as the producing area of authentic Sailonggu, and also, the cytb gene is a powerful molecular marker to determine the species of zokors as well as for the authentication of geographic distribution of Sailonggu.

OBJECTIVETo discuss arthroscopic technique of single Kirschner wire and suture avoiding epiphyseal line fixation for tibial intercondylar eminence fracture and its clinical results.

METHODSFrom May 2008 to December 2012, 21 patients (13 males, 8 females, ranging in age from 6 to 14 years old) with tibial intercondylar eminence fracture were treated arthroscopically with single Kirschner wire and suture avoiding epiphyseal line fixation technique. According to Meyers and McKeever classification, 7 patients were type II, 10 patients were type III, and 4 patients were type IV. Active rehabilitation began at one week after operation. The patients were followed up for 10 to 30 months. X-ray films were taken to evaluate fracture healing at 1, 3, 6 months after operation; range of motion, the anterior drawer test, the lachman test and the Lysholm knee score were used to evaluate clinical effects.

RESULTSAll fractures were healed without displacement at 6 weeks after operation. Anterior drawer test and the lachman test were both negative in all patients at 3 months after operation. Lysholm knee score was 95.5 ±2.5 at 6 months after operation, and postoperative X-ray film did not find epiphyseal line broadening or narrowing.

CONCLUSIONArthroscopic treatment for tibial eminence intercondylar fracture with single Kirschner wire and 8-shaped suture avoiding epiphyseal line fixation technique has many advantages, such as firm fixation,early mobilization, less invasive, less injury of physis and satisfactory effect.

This study was aimed to reveal the medication patterns of Chinese patent medicine in the treatment of breast hyperplasia based on association rules and clustering of data mining technology. Articles on Chinese patent medicine in the treatment of breast hyperplasia were retrieved from databases. External formulas or those mixed with western drugs were excluded. Terminologies in the selected formulas were standardized. Information was extracted to build excelltables. Association rules analysis and cluster analysis were used to reveal the medication patterns of Chi-nese patent medicine in the treatment of breast hyperplasia with software R2.15.2 and Cytoscape 2.8.3. The results showed that Chinese medicinals with higher frequency in 195 formulas were Radix bupleuri, Rhizoma cyperi, Chinese Angelica, Selfheal, White Peony Root, Trichosanthes kirilowii Maxim et al. Chinese medicinals with lower frequency were Chinese Alangium leaf, Rhinacanthus nasutus et al. The commonly used herbal pairs were Radix bupleuri -Chinese A ngelica, Rhizoma curcumae - Rhizoma sparganii, frankincense - myrrh et al. The strong association rules indicated that Xiaoyaosan, which takes Radix bupleuri and Chinese A ngelica as its core, is the key character of Chinese patent medicine in the treatment of breast hyperplasia. The cluster analysis revealed several Chinese medicine functional modules, such as Fructus forsythiae - Rhizoma smilacis glabrae - Evodia lepta - Chinese mahonia stem - Lignum millettiae et al. It was concluded that the herbal frequency, herbal pairs, strong associa-tion rules and cluster analysis can reveal the medication patterns of Chinese patent medicine in the treatment of breast hyperplasia in order to provide reference evidences in the optimization of clinical treatment for mula and im-provement of therapeutic efficacy.
