ObjectiveTo explore the feasibility and efficacy of hyperbaric oxygen (HBO) therapy combined with mild hypothermi on severe craniocerebral injury (SCI).MethodsAll 80 SCI patients were randomly divided into therapeutic group (52 cases) and control group (28 cases). All patients received general synthesis treatment; while the hyperbaric oxygen combined with mild hypothermia treatment was added to the therapeutic group. Changes of Vm, Vs and PI of middle cerebral artery (MCA) in systolic stage were detected by transcranial-Doppler (TCD) before and after treatment. The plasma level of endothelin (ET) was also tested and prognosis of patients was analyzed.ResultsVm, Vs and PI of MCA in systolic stage improved obviously and ET reduced greatly in therapeutic group compared with those in the control group (P<0.01), and prognosis was also superior to control group.ConclusionHyperbaric oxygen combined with mild hypothermia can improve the consciousness state and prognosis of SCI patients as a result of the relaxation of the cerebral vascular spasm and the reduction of ET, which may contribute to the abatement of the cerebral ischemia and hypoxia.

Chinese Journal of Integrated Traditional and Western Medicine 2002;22(6):429-431
OBJECTIVETo evaluate the efficacy and prospect of Fuzheng Jianpi Recipe (FZJPR) in treating children's Spleen deficiency anorexia (CSDA) by means of observing its effect on trace element content and immune function.
METHODSOne hundred and thirty cases of CSDA were treated with FZJPR, one dose per day in decoction, orally taken, 30 days for one therapeutic course. Levels of T-lymphocyte subsets, IL-2R, immunoglobulin and trace elements were determined before and after treatment, and compared with those in the control group consisted of 60 healthy children.
RESULTSIn the treated group, abnormal figures were shown in T-lymphocyte subsets, especially in lowering of CD3 and CD4 count before treatment, and IgG content was reduced also. After treatment, CD3, CD4, CD4/CD8 ratio as well as IgG and IgA were improved significantly (P < 0.01), IL-2R percentage approached normal. Moreover, the levels of Zn and Fe changed significantly (P < 0.01).
CONCLUSIONFZJPR could improve the trace elements content and immune function in CSDA children, so it is effective in treating CSDA.

[Summary] An analysis of clinical data was performed in 6 patients diagnosed as adefovir dipivoxil (ADV)-induced nephropathy in recent 14 months.The results showed that all of six patients suffered from pain over multiple joints after taking ADV 10-20 mg/d for 2-3 years,along with hypophosphatemia,hypouricemia,and raised osteogenesis index.One case had increased serum creatinine,5 cases had hypokalemia,renal glycosuria,and4 cases had albuminuria.Imageological examination showed osteoporosis,osteomalacia,and pseudo fracture.After discontinuance of ADV treatment,joint pain was obviously relieved within 3-6 weeks,blood uric acid level returned to normal within 1-2.5 months,and renal glycosuria and albuminuria disappeared by 1-2 months.The results suggest that after taking ADV for more than two years,attention should be paid to the nephropathy induced by ADV and regular monitoring of renal function,blood electrolyte,and urine should be mandatory.Hypouricemia is a reliable index of diagnosis and treatment in this event.

OBJECTIVETo explore the effect of combination therapy of tetramethylpyrazine (TMP) with methotrexate (MTX) on collagen induced arthritis (CIA) rats.
METHODSTotally 55 male SD rats were stratified by body weight. Nine of them were randomly recruited as the normal control group. The rest 46 were immunized with type II bovine collagen (C II) for establishing rheumatoid arthritis (RA) model. Forty successfully modeled rats were randomly divided into 4 groups according to swollen toe degree, i.e., the CIA group, the TMP group, the MTX group, and the TMP plus MTX group, 10 in each group. Rats in the MTX group were administered with MTX (1. 2 mg/kg) , once per week for 4 continuous weeks. Those in the TMP group were administered with 40 mg/kg TMP, once per day for 10 continuous days, and then discontinued for 7 successive days, and continued for another 10 successive days. Rats in the TMP plus MTX group were administered with a mixture of equal dose MTX and TMP, and when MTX was discontinue, TMP was administered according to the way in the TMP group. Equal volume of saline solution was given to rats in the normal control group and the CIA group. Clinical parameters including ankle width (mediolateral diameter) and hindpaw swelling were measured at day 0, 4, 11, 18, and 26 after treatment. Rats were sacrificed 28 days after treatment, their knee joints and ankle joints were collected for pathological analyses. Serum levels of IL-1β, IL-6, and IL-17A were detected by ELISA. Changes of fibrinogen (FIB) and platelet aggregation rate (PAg) were detected.
RESULTSCompared with the normal control group, the ankle width and hindpaw swelling increased significantly (P < 0.01), contents of FIB and PAg increased obviously (P < 0.05, P < 0.01), serum levels of IL-1β, IL-6, and IL-17 increased remarkably (P <0. 01) in the CIA group. Obvious cell proliferation, inflammatory cell infiltration, hyperemia and edema of synovial tissues could be seen. Pannus formed and immerged in cartilages, resulting in necrosis. Compared with the model group, changes of ankle width and hindpaw swelling were all alleviated in each medicated group (P <0. 05, P <0. 01). Of them, the effect was superior in the MTX group to that of the TMP group and the MTX plus TMP group (P < 0.05, P < 0.01). Contents of FIB, serum levels of IL-1β and IL-6 decreased significantly in the MTX group (P < 0.05). Contents of FIB, serum levels of IL-1β and IL-6 decreased significantly in the TMP group and the MTX plus TMP group (P < 0.05). Besides, serum levels of FIB and IL-6 were obviously lower in the MTX plus TMP group than in the TMP group and the MTX group (P < 0.01). Levels of PAg and IL-17A were more significantly lowered in the TMP group than in the MTX plus TMP group and the MTX group. Pathological changes could be alleviated in each medicated group, with the optimal effect obtained in the MTX plus TMP group.
CONCLUSIONCombination of TMP with MTX could significantly ameliorate inflammatory reactions and FIB contents of CIA rats.

OBJECTIVETo investigate effect of tumor necrosis factor-alpha (TNF-alpha) on the Src-suppressed C kinase substrate (SSeCKS) in C6 glioma cells.
METHODSCultured C6 glioma cells were randomly divided into two groups. In time-dependent group, cells were cultured with TNF-alpha (2 ng/mL) for 0 h, 1 h, 3 h, 6 h, 12 or 24 h, respectively; in dose-dependent group, cells were cultured with TNF-alpha (0 ng/mL, 0.02 ng/mL, 0.2 ng/mL, or 2 ng/mL) for 6 h. The expression of SSeCKS was detected by Realtime PCR and Western blot analysis, and immunocytochemistry was used to investigate SSeCKS's subcellular localization.
RESULTSTNF-alpha induced rapid phosphorylations of protein kinase C (PKC) substrates in C6 glioma cells, and upregulated SSeCKS expression in a time and concentration dependent manner. Immunocytochemistry suggested that SSeCKS was localized in the cyroplasm and the leading end of podosomal extensions in control groups, while TNF-alpha induced translocation of SSeCKS perinuclear. This effect could be partly reversed by PKC inhibitor Ro-31-8220.
CONCLUSIONTNF-alpha activates PKC and upregulates SSeCKS expression in C6 glioma cells. These effects are associated with PKC activity, suggesting that SSeCKS plays a role in response to glia activation in PKC mediated pathway.

OBJECTIVETo evaluate the effects of basic fibroblast growth factor(bFGF) on proliferation of periodontal fibroblast-like cells in vivo.
METHODSA U-shaped osseous defect was produced on the buccal side of the mesial root. Four posterior teeth were conducted in four quadrants. Each quadrant included 4 groups: control, bFGF, expanded polytetrafluoroethylene(ePTFE) membrane, bFGF + ePTFE. Each time the 4 teeth sites in one quadrant were operated weekly and each dog experienced 4 times of operations. Bromodeoxyuridine(BrdU) was injected 1 hour prior to sacrificing the dogs at 4 weeks after first surgery. Immunohistochemical method was applied to count the BrdU-labeled fibroblast-like cells.
RESULTSThe number of BrdU-labeled cells reached the maximum at the 2nd week among all groups and then, decreased with time. Both bFGF and bFGF + ePTFE treated group had significantly more BrdU+ cells than remained control or ePTFE groups (P < 0.05) at 1st, 2nd weeks after surgery.
CONCLUSION2 weeks after periodontal surgery is active phase of proliferation of periodontal fibroblasts. bFGF enhances fibroblast proliferation in early periodontal wound healing, and in turn accelerate periodontal regeneration.

This study was aimed to investigate whether mesenchymal stem cells (MSC) can be isolated from bone marrow filters which have always been discarded. The bone marrow (BM) particles from BM filters of 2 healthy donors were cultivated by primary explant culture. After expansion, the number of MSC was counted and their immunophenotype and differentiation potential were detected. The results indicated that many MSC were found in bone marrow particles from filters, and nearly 10(7) MSC were obtained at 3 passages of expansion. They not only possessed the characteristics of morphology and immunophenotype of MSC, but also could differentiate into osteoblasts, chondrocytes and adipocytes. In conclusion, a large amount of MSC can be obtained from BM filters if the BM particles were cultivated by primary explant culture.

OBJECTIVETo investigate the relationship between hypertriglyceridemic waist to height ratio phenotype (HWHtR) and chronic kidney disease (CKD) in a community population in South China.
METHODSA cross sectional study was conducted among 2142 residents in Zhuhai (Guangdong Province, China) from June to October of 2012. The HWHtR phenotype was defined as a waist to height ratio(WHtR) ≥0.55 and triglyceride level ≥2.0 mmol/L, based on which the participants were divided into HWHtR group and nonHWHtR group. CKD was defined as an eGFR<60 mL/min per 1.73 m2 or an ACR ≥30 mg/g. A logistic regression model was established to investigate the relationship between chronic kidney disease and HWHtR phenotype.
RESULTSCompared with the nonHWHtR group, the HWHtR group had a higher prevalence of chronic kidney disease (11.1% vs 33%, P<0.001). Analysis using the logistic regression model showed that HWHtR was significantly associated with CKD in the unadjusted analyses (OR=3.23, 95% CI: 2.32-4.48, P<0.001). After adjustment for age, sex, history of hypertension, history of diabetes, systolic blood pressure, diastolic blood pressure, drinking, physical exercise, education and current smoking, HWHtR was significantly associated with CKD (OR=2.36, 95% CI: 1.52-3.67, P<0.001); the association of HWHtR and CKD was still significant after further adjustment for BMI (OR=2.12, 95%CI: 1.34-3.35, P<0.001).
CONCLUSIONOur finding suggests that HWHtR is associated with CKD in this community population.

A transfer plasmid vector pUC18-US10-VP2 was first constructed by inserting the gene of the enhancer green fluorescent protein(eGFP) fused to the VP2 gene of very virulent Infectious bursal disease virus (IBDV) JS strain into the US10 fragment of the Marek's disease virus (MDV) CV1988/Rispens. The recombinant virus, designated as rMDV, was developed by co-transfecting CEF with the transfer plasmid vector and simultaneously infecting with the CVI988/Rispens virus. The PCR and IFA results indicated that the rMDV is stable after 31 passages. Chickens vaccinated with rMDV were protected from challenge with 100LD50 of IBDV JS. The protection ratio of the chickens vaccinated with the 1000PFU, 2000PFU, 5000PFU of the rMDV were 50%, 60%, and 80% respectively. It is interesting that the average histopathology BF lesion scores of chicken group immunized with 5000PFU of rMDV by one-time vaccination was close to that of chicken group vaccinated with IBDV live vaccine NF8 strain for twice (2.0/1.5). There is no difference in protection between the groups (P > 0.05) but significent difference between groups immunized with 5000 PFU of rMDV and with normal MDV. This demonstrated that rMDV expressing VP2 fusion protein was effective vaccine against IBDV in SPF chickens.
