Objective To study the expression difference of the insulin-like growth factor-I (IGF-I)and IGF-binding proteins-3,4,5(IGFBP-3,4,5)in the peripheral and local areas in senile hip fracture and discuss the correlation between the expression and the fracture types. Methods The study involved the senile patients (over 65 years) with hip fractures to compare the expressions of peripheral and local IGF-I and IGFBP-3,4,5 and observe the correlation between expression and fracture type.Results The serum and local specimens of 46 patients were collected,with lower level of BMD,IGF-I and IGFBP-3,5 in the intertrochanteric fracture group than the femoral neck fracture group(P<0.001)and with higher level of serum and local IGFBP-4 in the intertrochanteric fracture group than the femoral neck fracture group (P<0.001).Only local IGFBP-4 mRNA had positive correlation with serum markers (R=0.544,P<0.001). Conclusions The expression difference of IGF-I and IGFBP in the peripheral and local serum may be one of pathogenesis leading to different types of hip fractures.Except for the IGFBP-4,the other factors may affect the bone metabolism of the senile hip fractures through different regulatory mechanisms.

Objective To observe expression levels of N-methyl-D-aspartate (NMDA) receptor and cholecystokinin (CCK) in the hippocampus and spinal cord in morphine withdrawal or tolerance mice treated by electroacupuncture or catgut embedding and explore the difference between the regulating effects of electroacupuncture and catgut embedding on morphine withdrawal and tolerance.Methods Fifty-six male C57BL/6J mice were randomly allocated to withdrawal control, withdrawal model, withdrawal catgut embedding and withdrawal electroacupuncture groups, and tolerance control, tolerance model, tolerance catgut embedding and tolerance electroacupuncture groups, 7 mice in each group. A model of morphine withdrawal was made by subcutaneous injection of morphine hydrochloride using 7-day increasing addiction method. The withdrawal control group was injected with an equal volume of normal saline at the same time points. In the withdrawal electroacupuncture group, electroacupuncture at bilateral points Shenshu was performed using a Han’s acupoint nerve stimulation device (HANS-200) at 15 min after an injection of morphine hydrochloride. In the withdrawal catgut embedding group, 0.5 cm chromic catgut was embedded in bilateral points Shenshu at 15 min after an injection of morphine hydrochloride. Addiction was promoted by intraperitoneal injection of naloxone 4 mg/kg at 10 o’clock on the seventh day’s morning and Withdrawal reactions were observed in the mice. The score was recorded using the Ryuta Tomoji opioid withdrawal symptoms evaluation scale. NMDA receptor and CCK contents in the hippocampus and spinal cord were measured by enzyme-linked immunosorbent assay (ELISA). A model of morphine tolerance was made by subcutaneous injection of morphine 10 mg/kg. The tolerance control group was injected with tolerance normal saline 10 ml/kg at the same time. In the tolerance catgut embedding group, catgut was embedded in point Shenshu at the first day after model making. In the tolerance electroacupuncture group, point Shenshu was given electroacupuncture at the first day after model making. After seven days of treatment, NMDA receptor and CCK contents in the hippocampus and spinal cord were measured by ELISA.Results There were statistically significant differences in hippocampal NR2B and CCK expressions between the withdrawal model and withdrawal control groups (P<0.05). There was a statistically significant difference in hippocampal NR2B expression between the withdrawal electroacupuncture and withdrawal model groups (P<0.05). There was a statistically significant difference in hippocampal CCK expression between the withdrawal catgut embedding or withdrawal electroacupuncture group and the withdrawal model group (P<0.05). There were statistically significant differences in spinal cord NR2A, NR2B and CCK expressions between the withdrawal model and withdrawal control groups (P<0.05). There were statistically significant differences in spinal cord NR2A and NR2B expressions between the withdrawal electroacupuncture and withdrawal model groups (P<0.05). There were statistically significant differences in hippocampal NR2A, NR2B and CCK expressions between the tolerance model and tolerance control groups (P<0.05). There was a statistically significant difference in hippocampal CCK expression between the tolerance catgut embedding and tolerance model groups (P<0.05). There was a statistically significant difference in hippocampal NR1 expression between the tolerance electroacupuncture group and the tolerance model or tolerance catgut embedding group (P<0.05). There was a statistically significant difference in spinal cord CCK expression between the tolerance catgut embedding or withdrawal electroacupuncture group and the tolerance model group (P<0.05).Conclusions Both catgut embedding and electroacupuncture at point Shenshu have a reducing effect on morphine tolerance and withdrawal. The therapeutic effect of electroacupuncture is better than that of catgut embedding.

ObjectiveTo investigate the clinical characteristics of the inpatients suffering from dengue fever in order to provide references for better diagnosis and treatment.Methods The clinical data of 158 dengue fever patients admitted to the First Affiliated Hospital of Sun Yat-Sen University from July 23rd to October 31st, 2014 during the 2014 epidemic in Guangzhou area were retrospectively analyzed, including general clinical manifestations, conventional examinations, pathogenesis, and prognosis.Results The mean age of the 158 patients was (56±20) years, with half of them over 60 years old (79 cases). Among them, 94 (59.49%) were male.① The common manifestations included fever (100%), headache (70.89%), myalgia/bone soreness (62.03%), and skin rash (54.43%). Bleeding and plasma leakage were found in 25.95% and 14.56% of the patients respectively.② Laboratory examination:leucopenia (75.32%) and thrombocytopenia (77.85%) were found, and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were elevated in 57.59% and 77.85% of the patients respectively. However, elevation of blood hematocrit was rare (1.27%).③ It was found that in the acute phase (0 - 5 days of the onset), serum dengue virus antibody IgM (DF-IgM) was positive in 63.54% of the patients (61/96), and 92.62% (113/122) of patients were dengue virus RNA (DENA-RNA) positive.④ The rate of comorbidity in this study was 55.06% (87/158), including hypertension (27.22%) and type 2 diabetes (15.82%), which were the two most common co-morbidities.⑤ All the patients were given supportive therapy to prevent complications. They were also isolated for more than 5 days after onset, and at least for 24 hours after subsidence of fever in addition.⑥ The criteria for the diagnosis of severe dengue were fulfilled in 18 patients (11.39%). One patient died of massive hemorrhage from gastro-intestinal tract, and 1 patient voluntarily left hospital with untreated multiple organ dysfunction syndrome (MODS). Another 2 patients of dengue fever died from primary cardio-cerebrovascular disease, and the remaining 154 patients (97.47%) fully recovered with supportive therapy and complication prevention measures.Conclusions The clinical manifestations of inpatients with dengue fever in this study were typical, and they manifested a higher incidence of severe illness. DENA-RNA could be a sensitive indicator for early pathogenic diagnosis. With symptomatic and supportive therapy, most patients had a good outcome. However, early diagnosis and clinical interventions of severe dengue still need further studies.

Objective To investigate the clinical efficacy of intermittent liver-nourishing and mind-regulating acupuncture in preventive treatment of migraine. Method One hundred and twenty migraine patients were randomly allocated to treatment and control groups, 60 cases each. The treatment group received intermittent liver-nourishing and mind-regulating acupuncture and the control group took flunarizine hydrochloride capsules orally. The migraine score, the visual analogue scale (VAS) score and the headache severity rating score were recorded in the subjects before treatment and at the end of treatment and the 4-week, 8-week, 12-week, 16-week and 20-week follow-ups. The Self-Rating Anxiety Scale (SAS) score and the Self-Rating Depression Scale (SDS) were recorded before and after treatment.Result After one course of treatment, the total efficacy rate was 98.3% in the treatment group and 89.5% in the control group; there was a statistically significant difference between the two groups (P<0.05). There was a statistically significant difference in the migraine score between before treatment and at the end of treatment in the two groups (P<0.05) and between the two groups at the same follow-ups (P<0.05). There was a statistically significant difference in the VAS score between before treatment and at the end of treatment in the two groups (P<0.05) and between the two groups at the same follow-ups (P<0.05). There were statistically significant differences in the SAS and SDS scores between before treatment and at the end of treatment in the two groups (P<0.05) and between the two groups after treatment (P<0.05).Conclusion Intermittent liver-nourishing and mind-regulating acupuncture has marked efficacy in preventive treatment of migraine. It can increase the total efficacy rate and reduce the number of relapses.

A subcellular proteomic method was applied to investigate the protein expression profiles of nasopharyngeal carcinoma (NPC) cell lines,CNE1 and CNE2,at various differentiation levels.Plasma membrane (PM) proteins were obtained by Percoll density grade centrifugation and subjected to twodimensional electrophoresis (2DE) followed by PDQuest software analysis.Nine proteins expressed with more than two folds difference were identified by MALDI-TOF-TOF,of which functions involved in cell differentiation,signal transduction,and metabolism.Half of these proteins,such as galectin-1 and annexin Ⅱ,were analyzed with real-time quantitative PCR or Westem blotting.We have tested a proteomic method to study differentiated NPCs at different levels and found several proteins that might be related to their biological characteristics.

Objective To observe the clinical efficacy of heat-sensitive moxibustion plus point-toward-point needling in treating poststroke strephenopodia.Method Eighty patients with poststroke strephenopodia were randomized into a treatment group intervened by heat-sensitive moxibustion plus point-toward-point needling and a control group intervened by rehabilitation, 40 cases in each group. In addition to the basic treatment, the treatment group was given heat-sensitive moxibustion plus point-toward-point needling, and the control group was given rehabilitation treatment. Holden's Functional Ambulation Classification (FAC), Fugl-Meyer Assessment (FMA) of the lower-limb motor function, and Tinetti Gait Assessment (TGA) were adopted for evaluation of the two groups, and the clinical efficacies were compared.ResultThe effective rate was 90.0% in the treatment group versus 77.5% in the control group, and the difference was statistically significant (P<0.05); after the treatment,there was a significant difference in comparing the Holden's FAC between the two groups (P<0.05); the FMA score changed significantly after the treatment in both groups (P<0.05), and there was a significant difference in comparing the FMA score between thetwo groups after the treatment (P<0.05); the TGA score changed significantly after the intervention in both groups (P<0.05), and there was a significant difference in comparing the TGA score between the two groups after the intervention (P<0.05).ConclusionHeat-sensitive moxibustion plus point-toward-point needling can produce a significant efficacy in treating poststroke strephenopodia, as it can enhance the effective rate and improve the lower-limb motor function.

OBJECTIVEThis study was designed to detect the expression of bcl-2 and p53 proteins in colorectal carcinomas and to determine their association with the patient survival and stage of the diseases.

METHODSImmunohistochemistry method was used to detect the expression of bcl-2 and p53 proteins in 93 cases of colorectal carcinoma. The stain results were obtained by analyzing the clinic-pathological characteristics of patients.

RESULTSFifty-seven percent (53/93) of the colorectal carcinomas were bcl-2 protein positive. The positive rate of bcl-2 protein in lymph node involvement cases was lower (15/37) than the cases without node involvement (38/58, P<0.01). The positive rate of p53 protein was 43% (40/93) in colon-rectum carcinomas. No significant correlation was observed between p53 protein expression and clinic-pathological manifestations (P>0.05) but the survival was significantly worse (P=0.0001) in the p53 protein positive cases. Neither bcl-2 nor p53 alone was correlated with stage of the disease. When combined bcl-2/p53 status was analyzed, a group with bcl-2(+) and p53(-) had the best prognosis. This group was significantly associated with earlier Dukes' stages (P=0.1763). In multivariate Cox regression analysis, lymph node involvement and p53 protein expression were two independent factors correlated with survival time.

CONCLUSIONThe expression of bcl-2 and p53 represent biological characteristics of colorectal carcinomas. Assessment of both bcl-2 and p53 status may be valuable in predicting the prognosis of patients.

OBJECTIVETo determine the safety and efficacy of total percutaneous endovascular abdominal aortic aneurysm repair using the Perclose ProGlide suture-mediated closure system.

METHODSFrom May 2008 to April 2010, 36 abdominal aortic aneurysm patients were undergone total percutaneous endovascular repair. There were 30 male and 6 female patients with a mean age of 68 years. Endografts used included 3 Endurant endografts, 13 Talent endografts, and 20 Zenith endografts. Prior to insertion of the introducer sheath, two ProGlides were pre-set to 18 to 24 F access sites and one to 14 to 16 F access sites. At last, suture the arteriotomy by tying down knots of the ProGlide following removal of the sheath. Technical success, complications, and procedure and access closure times were evaluated. Follow-up protocol consisted of computed tomography angiograms performed at 3, 6, 9, 12 months, and annually thereafter.

RESULTSTwenty patients were operated under local anesthesia and 16 patients under general anesthesia. A total of 68 femoral arteries were closed with 128 devices. Thirty-eight vessels were with 2 devices, while 8 arteries required 3 devices and 2 arteries required 4 devices for hemostasis and an additional 20 vessels only required a single device. Sixty-three (63/68, 92.6%) vessels were closed successfully. Two vessels converted to open closure. Three vessels complicated with hematomas without surgical procedure. The mean follow-up was (12±3) months. There was one asymptomatic femoral artery dissection 3 months after operation.

CONCLUSIONSTotal percutaneous endovascular abdominal aortic aneurysm repair is safe and effective. But it should be performed at hybrid operating room where can convert to open procedure if necessary.
