OBJECTIVETo observe the efficacy of He-wei Jie-gu (Chinese characters) decoction on femoral intertrochanteric fractures after internal fixation in elderly.

METHODSFrom January 2010 to January 2012, 90 elderly patients with osteoporotic intertrochanteric fracture were randomly divided into two groups. The patients in experimental group were treated with open reduction and internal fixation, He-wei Jie-gu decoction and Caltrate D in oral, including 18 males and 27 females with an average age of (77.8±11.3) years old ranging from 65 to 89 years old;the time from injured to operation was 2 to 9 days with an average of (6.6±2.1) days; according to Evans-Jensen classification, 17 cases were in type I, 8 in type II, 15 in type III, 3 in type IV, 2 in type V. Meanwhile, the patients in control group were treated with open reduction and internal fixation, Caltrate D in oral, including 16 males and 29 females with an average age of (81.2±9.6) years old ranging from 67 to 91 years old; the time from injury to operation was 2 to 10 days with an average of (6.8±2.6) days; according to Evans-Jensen classification, 15 cases were in type I, 10 in type II, 14 in type III, 4 in type W, 2 in type V. The VAS score, hip BMD value before and after treatment, fracture healing and the Harris function score after operation were recorded and compared.

RESULTSAll patients were followed up from 3 to 9 months with an average of (5.6±2.8) months. Compared with the control group, the VAS score of the experimental group had an obviously reduction (F=98.138, P<0.01) after treatment; the hip BMD value at 3 months after treatment in the experimental group was higher than that of the control group (P<0.05); the fracture healing rate of the experimental group was higher than that of the control group (P<0.05); Harris score in 3 months of follow-up in the experimental group was higher than that of the control group (t=2.542, P<0.05); all the differences between two groups were statistically significant (P<0.05).

CONCLUSIONHe-wei Jie-gu decoction can reduce postoperative pain and increase bone mineral density after internal fixation of femoral intertrochanteric fracture in elderly, promote the fracture healing and functional recovery in the hip joint.

The type of basic media and the contents of plant growth substances were investigated by orthogonal design experiment,and also the effects of different culture conditions on the growth of suspension cells and the accumulation of total flavonoids in Eucommia ulmoides were studied.The results showed that B5 medium supplemented with 0.5mg/L NAA,0.6mg/L 6-BA and 30g/L sucrose,at initial pH 5.0～5.5,20g(FW)/L inoculation quantity and 110 r/min of rotation speed was a preferable culture conditions for E.ulmoides suspension cells growth and flavonoids synthesis.The results of metabolic kinetics analysis for E.ulmoides cell suspension culture showed that the logistic and Luedeking-Piret equations can be used for describing the kinetics of cell growth,sucrose consumption and flavonoids production during the process.The maximum specific growth rate(?m),the actual growth yield based on sucrose(YG) and maintenance coefficient(m) were 0.417/d,0.619g/g and 0.0206g/(g?d-1) respectively.All these outcomes could give a basis for establishing the suspension cell culture of E.ulmoides and production of the natural active components in large-scale.

In temporomandibular disorders (TMD), pain takes place when neuropeptides stimulate synovial tissue to produce several cytokines such as interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α, which activate neurons and glia of synovial membrane at the bilaminar regions of temporomandibular joint (TMJ). It has been reported that, after neurogenic differentiation, the synovial mesenchymal stem cells (SMSCs), deriving from TMJ, possess the same cytological features as the neuronal cells. This study examined the ability of substance P (SP) and calcitonin gene-related peptide (CGRP) to stimulate SMSCs and neurogenic SMSCs secreting inflammatory cytokines during TMD, evaluated the mutual effects of inflammatory cytokines and neuropeptides and tested the analgesic effect of hyaluronic acid (HA). The levels of IL-1β, IL-6 and TNF-α in SMSCs and neurogenic SMSCs in the presence of neuropeptides were measured by ELISA. SP and CGRP produced by SMSCs and neurogenic SMSCs were determined by RT-PCR and Western blotting. The results showed that the expression of SP and CGRP was significantly enhanced in the neurogenic SMSCs in response to IL-1β, IL-6 and TNF-α, and the effect was remarkably inhibited by HA. IL-1β, IL-6 and TNF-α, in return, could be enhanced in the neurogenic SMSCs upon stimulation by SP and CGRP. Neuropeptides and inflammatory cytokines might work mutually on the TMD pain. The HA-mediated analgesic effect may be implicated in the inhibition of SP and CGRP expression in neurogenic SMSCs.

Phosphodiesterase 4 (PDE4) is an important member of the phosphodiesterase enzyme family that specifically catalyzes the hydrolysis of cyclic adenosine monophosphate (cAMP), activates the downstream phosphorylation cascade pathway by altering cAMP concentration, and is strongly associated with multiple diseases. Inhibition of PDE4 is clinically investigated as a therapeutic strategy in a broad range of disease areas, including respiratory system diseases, autoimmune disorders, central nervous system diseases, and dermatological conditions. However, the incidence of adverse reactions such as nausea and vomiting is relatively high in the marketed PDE4 inhibitors, which has stalled their clinical development. In this review, we provide an overview of the clinical progression and safety issues of the marketed PDE4 inhibitors. We also review the main causes underlying PDE4-mediated adverse effects by combining the structural analysis of the PDE4 protein, the mechanism of action of PDE4 inhibitors, and the related side effect mechanism research, aiming to provide a reference for the development of safe and effective PDE4 inhibitors.

OBJECTIVETo investigate the status of genital infection as well as distribution of types of human papillomavirus (HPV) in women in Shenzhen and provide population data for the future vaccine intervention on cervical cancer.

METHODSWomen with age between 15 and 59 years were selected in cluster stratified sampling from Huaqiaocheng community, Nanshan district, Shenzhen and received a population-based cervical cancer screening. After consent, every woman was interviewed by using questionnaire and tested by liquid-based cytology and HPV DNA (hybrid capture 2 and gene chips typing) separately.

RESULTSTotally 1 137 women were screened. The rate of high risk HPV of hybrid capture 2 test (14. 0% ) was higher than gene chips typing test (9. 8%) (chi(2) = 27. 198, P < 0. 001) ; the consistency of the two tests was acceptable ( kappa = 0. 498, P < 0. 001). The rates of low risk HPV types and other types of gene chips typing test in this population were 1. 9% and 0. 2% respectively. The percentages of HPV 16, 18 and 58 in HPV positive women were 29. 7% , 18. 9% and 18. 9%. The rates of different age group of low risk HPV were 1. 4% (17-34), 1. 7% (35-44) and 3. 2% (45-59) , respectively.

CONCLUSIONSHPV 16, 18, and 58 are the most popular types in the study population. The differences of infection rates of high risk HPV are due primarily to the variation of HPV16 distribution among age-specific population. The chances of being affected by low risk HPV will increase with age.

The dosage-efficacy/toxicity relationship of the 50% alcohol extracts of Polygonum multiflorum was comparatively investigated on either normal or CCl4-induced chronic liver injury rats, by determining the general condition, serum biochemical indices and liver histopathology, coupled with the factor analysis. The dosages were 10 and 20 g raw materials per kg body weight. Compared with the normal control group, the normal high dose group showed significant increases of the serum alanine transaminase (ALT), total bilirubin (TBIL), high mobility group box 1 (HMGB-1) and interleukin-1β (IL-1β) (P < 0.05 or P < 0.01), as well the frequent incidences of inflammatory cell infiltration, hepatic sinus enlargement and fiber stripes formation in histopathological sections. Compared with the model control group, the model low dose group showed significant declines of serum ALT, aspartate transaminase (AST) and total bile acid (TBA) (P < 0.05), as well the alleviation of vacuoles of hepatocytes, but no amelioration of the inflammatory cell infiltration and fibrous tissue hyperplasia; moreover, the model high dose group showed significant degeneration declines of serum HMGB-1, tumor necrosis factor-α (TNF-α) and IL-1β (P < 0.05, P < 0.01), as well the evident alleviation of vacuoles degeneration of hepatocytes, inflammatory cells infiltration and fibrosis degree. The factor analysis showed that the low dosage treatment had almost neither injuring effect on the normal rats nor protective effect on the model rats; while the high dosage treatment showed observable injuring effect on the normal rats, expressed by the significant increases of the factor-1 (HMGB-1, TNF-α and IL-1β as the main contributors) and factor-2 (TBIL, ALT and TBA as the main contributors) relative to the normal control group. The liver protective effect of the high dosage treatment could be observed with the significant reduction of the factor-1, indicating the effective alleviation of the expression of inflammatory cytokines. In conclusion, it could illustrated the phenomenon of symptom-based prescription theory of Polygonum multiflorum on rat livers: the high dosage of the herb had either an injuring effect on normal rats, or a therapeutic effect on the rats with chronic liver injury.
