OBJECTIVETo investigate the therapeutic effect of Yiqi Huaju Recipe (YHR) combined with routine therapy on the blood pressure, the blood pressure variability and other cardiovascular risk factors in hypertension patients complicated with metabolic syndrome (MetS).

METHODSTotally 43 hypertension patients complicated with MetS were recruited in this study and randomly assigned to the treatment group (22 cases, treated with basic routine treatment +YHR) and the control group (21 cases, treated with basic routine treatment + placebo). The treatment course was 12 weeks. Detected were parameters such as 24-h ambulatory blood pressure monitoring (ABPM), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR), fasting glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PPG), fasting plasma insulin (FPI), serum lipid, etc.

RESULTSThe anthropometric parameters and plasma glucose levels (except HbAlc) were obviously lowered after treatment than before treatment in the treatment group (P < 0.01, P < 0.05). Besides, better effects were obtained in the WC, WHR, 2 h PPG, FPI and HOMA-IR (P < 0.05). The average blood pressure amplitude, the blood pressure variability, and blood pressure load at any time point were more obviously improved in the two groups after treatment than before treatment (P < 0.01, P < 0.05). Besides, partial indices were better in the treatment group than in the control group (P < 0.01, P < 0.05).

CONCLUSIONSYHR combined with routine therapy exhibited better effect on reducing the blood pressure amplitude, the blood pressure variability, and the blood pressure load in hypertension patients complicated with MetS. It could also effectively decrease the risk of other vascular disease.

This study was purposed to investigate the angiogenesis-promoting activities of human mesenchymal stem cells (hMSCs) modified by hepatocyte growth factor (HGF) and the underlying mechanisms. The hMSCs were transfected by recombinant adenoviral vector carrying human HGF gene and seeded onto the chicken chorioallantoic membrane. Three days later, the number of blood vessels was counted and their angiogenic response was compared with those of hMSCs of same generation, recombinant basic fibroblast growth factor (bFGF) and alpha-MEM as control. The expression levels of bFGF, VEGF, angiopoietin-1 and angiopoietin-2 were evaluated by RT-PCR assay. The results showed that gene-modified hMSCs exhibited greatest activity to promote angiogenesis while the angiogenic response was nearly same between groups treated by hMSCs and bFGF, all of which were significantly higher than that observed in control (p < 0.01). RT-PCR analysis revealed that hMSCs constitutively expressed multiple angiogenesis-associated growth factors and their levels seemed up-regulated by HGF gene transfer. It is concluded that HGF gene-modified hMSCs show a potent angiogenesis-promoting function and may be useful in the treatment of ischemic disorders.

OBJECTIVETo explore clinical outcomes and advantages of anterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal tuberculosis.

METHODSFrom February 2010 to February 2014, totally 82 patients with lumbar spinal tuberculosis were treated by posterior individual fixation with small-incision focus debridement,including 50 males and 32 females with an average of 50.5 years old. All patients were divided into two groups according to different procedures. Forty-nine patients in group A were treated with anterior small-incision focus debridement with posterior internal fixation through muscle spa ring at stage I ; and 33 patients in group B were treated with focus debridement with posterior internal fixation by extraperitoneal approach at stage I . Postoperative mechanical ventilation time, preoperative and postoperative Cobb angle, visual analogue scale (VAS), erythrocyte sedimentation rate (ESR) and Frankel grading were observed and compared. Postoperative complications, stability of internal fixation and bone union were compared.

RESULTSAll patients were followed-up from 15 to 36 months with an average of 23.7 months. Psoas abscess of three patients in group A and 1 patient in group B on the opposite side increased and were healed by the secondary apocenosis. The other 78 cases were healed at stage I, and no sinus tract formation, incisional hernia, leakage of cerebrospinal and occurrence of spinal tuberculosis were occurred. Fracture healing time ranged from 3 to 7 months with an average of 4.6 months. Postoperative mechanical ventilation time and VAS score in group A was better than group B. There were no statistical differences in Cobb angle, ESR and Frankel grading at the final following-up between two groups.

CONCLUSIONAnterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal according to degree of damage is a safe and effective method.

OBJECTIVETo improve the diagnosis and treatment of testicular teratoma in children by analysis of clinical data.

METHODSWe retrospectively analyzed the clinical data about 64 cases of testicular teratoma treated in the Children's Hospital of Chongqing Medical University from 1995 to 2014.

RESULTSSixty-one of the cases presented painless scrotal mass with a sense of bearing down and the other 3 cases were confirmed because of empty scrotum diagnosed as cryptorchidism. The level of serum alpha fetal protein ( AFP) was obviously increased in 46 cases but normal in the other 18 preoperatively. Ultrasonography manifested abnormal inhomogeneous echo zones with calcification or necrosis. X-ray examination presented patchy or curvilinear high-density shadows in 28 cases. Forty-one of the patients underwent testis-sparing surgery (TSS) , 20 received high inguinal orchiectomy, and 3 refused surgical treatment. Pathological examination revealed 3 mature germinal layers in the 49 cases of mature teratoma and immature germinal tissue, including the original neural tube, and 11 cases of immature teratoma. The mature cases were exempted from chemotherapy, while the immature cases received the combination of cisplatin, etoposide, and bleomycin (PEB). The patients were followed up for 2 years postoperatively, which revealed no recurrence or metastasis.

CONCLUSIONMost children with testicular teratoma presented painless scrotal mass with a sense of bearing down and with abnormal serum AFP in most cases. Ultrasonography and plain radiography of the scrotum contribute to the diagnosis of the tumor. TSS is the main treatment option and intraoperative frozen-section can help the surgeons decide on the surgical mode. Postoperative chemotherapy is necessitated for immature teratoma but not for mature cases.

OBJECTIVETo explore the value of detecting bacterial 16S rRNA with 23S rRNA in the diagnosis of periprosthetic joint infection (PJI).

METHODSA prospective study was conducted among 67 patients with previous total hip arthroplasty (THA) undergoing a reoperation for infection (23 patients) or aseptic loosening (44 patients). Bacterial 16S rRNA and 23S rRNA in the interface membrane were detected by real-time PCR and their value in diagnosis of PJI was assessed.

RESULTSThe 16S rRNA and 23S rRNA showed no significant difference in their power in the diagnosis of PJI. The detection of 16S rRNA/23S rRNA showed a higher sensitivity and a greater negative predictive value in PJI diagnosis than the detection of 16S rRNA+23S rRNA (95.7% vs 52.2%, P<0.01; 97.6% vs 79.6%, P=0.01). The specificity, positive predictive value, and accuracy of the 4 diagnostic strategies were not significantly different.

CONCLUSIONSThe diagnostic power of 16S rRNA and 23S rRNA was similar in detecting PJI. Compared with the diagnostic strategy with 16S rRNA+23S rRNA, 16S rRNA/23S rRNA is more sensitive in detecting PJI.

OBJECTIVETo detect hot point mutations of ATP7B gene in Hunan Han patients with Wilson' disease (WD).

METHODSThe genomic DNA of 22 WD patients was extracted and exons 5, 8, 12, 13 were amplified by PCR. Screening for the mutations was done by direct sequencing and analysed by BLAST.

RESULTSFifteen of the 22 patients were found with mutations. Ten heterozygous Arg778Leu (2273G --> T) mutations were found in exon 8, all of them were accompanied with 2250C --> G polymorphism (Leu770Leu). Seven patients were found with 2855G --> A (Arg952Lys) polymorphism (4 heterozygous and 3 homozygous), 3 of them had Arg778Leu mutation in exon 8 and one with heterozygous mutation Gly943Asp (2828G --> A) in exon 12 simultaneously. Only one patient was found with heterozygous Pro992Leu (2975C --> T) mutation in exon 13. No mutations were found in exon 5.

CONCLUSIONArg778Leu is the hot point mutation of ATP7B gene in Hunan Han patients with Wilson' disease while exon 5 is not.

OBJECTIVETo investigate the protective effect and mechanism of Shenqi Compound on diabetic angiopathy modeled rats.

METHODSTotally 18 SD rats were randomized into 3 groups, i.e., the normal control group, the diabetic mellitus (DM) group, and Shenqi Compound group, 6 in each group. The DM rat model was established by feeding high-fat diet (to induce hyperlipidemia) +intraperitoneal injection of small dose streptozotocin (STZ). Shenqi Compound was given to rats in the Shenqi Compound group at the daily dose of 2 g/kg. Equal volume of normal saline was given to rats in the model group and the normal control group by gastrogavage. All treatment was lasted for 12 weeks. Then 2-D and ultrasonic integrated backscatter technique were used to evaluate structural and functional changes of abdominal aorta in the progression of diabetic macroangiopathy. The fibrosis degree of the aorta vessel and myocardium capillaries were observed by using HE and Masson trichrome staining. The tension of the aortic vascular ring was determined. The transforming growth factor beta (TGF-beta) mRNA expression was detected by real time PCR (RT-PCR). The protein expression of TGF-beta, collagen I, collagen III, connective tissue growth factor (CTGF), and phosphorylation P38 MAPK were detected by Western blot.

RESULTSCompared with the normal control group, abdominal aortic systolic inner diameter, diastolic inner diameter, Peterson elastic modulus, stiffness index, and backscatter integral significantly increased; the rangeability of integral backscatter and the extension coefficient of cross section significantly decreased in the DM group (all P < 0.05). After 12 weeks aforesaid indices were obviously improved in the Shenqi Compound group (P < 0.05). Results of HE and Masson staining showed that the fibrosis degree of the aorta vessel and myocardium capillaries was obviously alleviated in rats of the Shenqi Compound group (P < 0.05). Results of the aortic vascular ring tension showed that acetylcholine induced vasodilatation and maximum diastolic percent were obviously elevated in the Shenqi Compound group (P < 0.05). Compared with the normal control group, the mRNA expression of TGF-beta, and the protein expression of TGF-beta, collagen I, and collagen III, and phosphorylation of P38 MAPK all significantly increased in the DM group (P < 0.05). Compared with the DM group, the mRNA expression of TGF-beta, and the protein expression of TGF-beta, collagen I, and collagen III, and phosphorylation of P38 MAPK all decreased (P < 0.05).

CONCLUSIONSShenqi Compound could effectively improve the arterial function in diabetic marcoangiopathy and microvascular dysfunction. The mechanism might be due to the down-regulating the expression of TGF-beta, and further suppressing the phosphorylation of P38 MAPK, reducing the synthesis of collagen I and collagen III, therefore, ameliorating arterial and myocardial interstitial fibrosis.

OBJECTIVETo study the effect of hepatitis C virus nonstructural protein 3 N-terminal protein (HCV NS3-5') on hepatocyte transformation and tumor development.

METHODSQSG7701 cells were transfected with plasmid pRcHCNS3-5' (expressing HCV NS3 N-terminal protein) by lipofectamine and selected in G418. The expression of HCV NS3 gene and protein was determined by PCR and immunohistochemistry respectively. Biological effect of transfected cells was observed through cell proliferation assay, anchor independent growth, and tumor development in nude mice. The expression of HCV NS3 and c-myc protein in the induced tumor was evaluated by immunohistochemistry.

RESULTSHCV NS3 was strongly expressed in QSG7701 cells transfected with plasmid pRcHCNS3-5' and the positive signal was located in cytoplasm. The HCV NS3 expression and c-myc protein in the induced cytoplasm. Cell proliferation assay showed that the population doubling time in the pRcHCNS3-5' transfected cells was much shorter than that in the pRcCMV and non-transfected cells (24 h, 26 h, 28 h respectively). The cloning efficiencies of transfected cells with pRcHCNS3-5', pRcCMV and non-transfected cells were 33.0%, 1.5%, 1.1% respectively (P < 0.01). Tumor developed in nude mice inoculated with pRcHCNS3-5'transfected cells 15 days after the inoculation. HE staining showed hepatocarcinoma character and immunohistochemistry confirmed HCV NS3 and c-myc expression in the tumor tissue. The positive control group also showed tumor development, while no tumor mass obtained in the nude mice inoculated with pRcCMV and non-transfected cells even 40 days after the injection.

CONCLUSIONHCV NS3 N-terminal protein showed cell transformation and tumorigenic features.

OBJECTIVETo investigate the personality traits and intensity dependence of auditory evoked potentials (AEPs) in chronic primary insomnia.

METHODSThirty-seven patients with chronic primary insomnia (insomnia group) and 44 healthy subjects (control group) were enrolled in the study. The AEPs were examined in insomnia and control groups; the personality traits were studied by Zuckerman's Sensation Seeking Scales (SSS) and Zuckerman-Kuhlman's Personality Questionnaire (ZKPQ); and the mood states by Plutchik-van Praag's Depression Inventory (PVP).

RESULTThe scores of neuroticism-anxiety and depression in insomnia group were significantly higher than those in control group (P<0.01); and the scores of impulsivity and aggression-hostility were also higher than those in control group (P<0.05); N1-P2 amplitude of AEP increased with stimulus intensity, which were significantly different in 70, 80, 90,100 dB (P<0.01). There were significant correlations between activity and N1 latency at 80 dB, activity and P2 latency at 100 dB (r=0.270, r=0.276, P<0.05); and between total scores of sensation seeking scale and N1-P2 amplitude (r=0.3746, r=0.35329, P<0.01) at 70 and 90 dB stimulus intensity in insomnia group. There were significant correlations among experience seeking and N1-P2 amplitude, experience seeking and slope rate (P<0.01) at 70, 80, 90, 100 dB stimulus intensity in insomnia group (r=0.539, r=0.3439, r=0.439, r=0.3278). There were significant correlations between sensation seeking of boredom susceptibility and slope rate (r=-0.282998, P<0.05) in insomnia group. There were significant correlations between thrill and adventure seeking and N1-P2 amplitude(r=0.2789, P<0.05) at 90 dB stimulus intensity in insomnia group; there were significant correlations between PVP and N1-P2 amplitude (r=-0.3434, r=-0.3158, P<0.05) at 70 dB and N1 latency at 80 dB in insomnia group.

CONCLUSIONChronic primary insomnia sufferers have higher levels of neuroticism-anxiety, depression, aggression-hostility and impulsivity, and some are correlated with stimulus intensity dependence in AEP.
