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 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

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.

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.

Objective: To observe the clinical efficacy of balancing acupuncture therapy in the treatment of chest pain following lung cancer. Methods: Twenty-four cases of primary bronchial lung cancer with chest pain were treated by balancing acupuncture therapy; the relief of chest pain and its relief time were observed. Results: Among the 24 cases undergoing balancing acupuncture therapy, the chest pain was absolutely relieved in 3 cases, partially relieved in 13 cases, lightly relieved in 4 cases and not relieved in 4 cases; the total response rate was 83.3%. In terms of the relief time, 9 cases responded to the balancing acupuncture therapy in 0-3 min, accounting for 37.5%; 5 cases responded in 4-6 min, accounting for 20.8%; the average responding time was (4.85±1.45) min. Conclusion: Balancing acupuncture therapy is rapid-acting, safe, convenient and inexpensive in the treatment of chest pain following lung cancer.

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.

Objective To explore the feasibility of employing a risk category system in evaluating the treatment outcome of locoregionally advanced nasopharyngeal carcinoma (NPC) treated by intensitymodulated radiation therapy (IMRT) alone,and offering evidence for relevant perspective studies.Methods Totally 185 locoregionally advanced NPC patients were divided into high-risk and low-risk groups for evaluation and comparison.The patients who met at least one of the following criteria were defined as high-risk group and others as low-risk group:GTVnx ＞ 30 cm3;Clinical stage T4N2M0;multiple neck node metastases with 1 node size ＞4 cm,and N3 with any T stage.Results With a median follow up of 110.9 months (6.7-152.4 months),the 5-year overall survival,locoregional relapse-free survival,distant metastasis-free survival for the high-risk group vs.the low-risk group were 61.0％ vs.90.5％ (x2 =30.298,P＜0.05),78.3％ vs.91.5％ (x2 =6.352,P＜0.05)and 71.6％ vs.92.0％ (x2 =16.346,P ＜0.05).Conclusions As a simple and practicable method,the risk category system is helpful for discriminating locoregionally advanced nasopharyngeal carcinoma with different risk-group of treatment failure and in further perspective clinical research.

Objective To report the clinical outcome and prognostic factors for locally recurrent nasopharyngeal carcinoma(NPC)treated with intensity modulated radiotherapy(IMRT).Methods From January 2001 to August 2004,the data of 132 such NPC patients were analyzed retrospectively;104 male and 28 female with a median of 44.5 years(range 21-73 years).Ninety-eight patients(74.2%)were confirmed by biopsy as having NPC:9 with WHO TypeⅡand 89 WHO TypeⅢ.The other 34 patients were only diagnosed by MRI scan because of the extension/invasion was in the base of skull and/or cavernous sinus.Median interval time were 24 months(range 6-184 months).According to the 1992 Chinese Fuzhou Staging System:stageⅠ3.8 %,Ⅱ10.6 %,Ⅲ22.0% andⅣa 63.6%;T1 5.3%,T2 10.6%,T3 22.7% and T4 55.3%.Twenty-two patients had recurrence in the neck lymph nodes.IMRT was given with the sequential tomotherapy system(NOMOS Peacock systems)of 6 MV X-rays.Prescription dose was 60-70 Gy in GTV,with the fractional dose of 1.94-2.8 Gy.Sixty patients were also supplemented with two to six courses of cisplatin-based chemotherapy.Results The median volume of GTV was 39.5 cm~3(range 0.8-158.9 cm~3).The D95,V95,mean dose and fractionation dose of GTV was 66.9 Gy,98.3%,69.8 Gy and 2.32 Gy,respectively.The median follow-up time was 12 months(range,2-47 months).The 1-,2-and 3-year local progression-free rate was 96.4%,88.4% and 85.3%,respectively.The overall 1-,2-and 3-year survival rate was 6.5.9%,49.6% and 41.6%,respectively.Eleven patients developed distant metastases.Forty-seven patients were observed to devdop mucosa necrosis and/or massive hemorrhage in the nasopharynx.On univariate and multivariate analysis,fractional dose and vohane of GTV were significant prognostic factors for overall survival(P=0.016,0.009).Conclusions The local control and survival rate can be improved for patients with locally recurrent nasopharygeal carcinoma after treatment of intensity modulated radiotherapy.The fractional dose and volume of GTV are independent prognostic factors for the overall survival. The main death reasons are mucosa necrosis and/or massive hemorrhage in the nasopharynx.
