Objective To find out the difference between fetal malnutrition (FM) and small for gestational age (SGA) and its clinical significance. Methods Clinical nutritional status was assessed in 548 singleton term babies. Nine superficial, rapidly detected signs of malnutrition were taken for the clinical assessment nutritional status score (CANSCORE). FM was diagnosed if the total score was less than or equal to 24. Results Among 40 SGA, 21(52.5%) were FM, the other 19 (47.5%) were not FM with scores more than 24, whereas 13(2.8%) out of 508 AGA (appropriate for gestational age) were FM. Conclusion SGA and FM are not synonymous and FM can be rapidly determined by the CANSCORE. Biochemical and ultrasonic studies should be done in high risk preg nancy during second trimester to discover FM and intervene by nutritional treatment to prevent the infants with FM.

Sphingosine-1-phosphate receptor 1(S1PR1) is a new member of G protein-coupled receptor family. A great body of data suggest S1PR1 is capable of regulating lots of downstream signaling molecules and cellular processes. It is found that S1P/S1PR1 plays an important role in the development and mainte-nance of pain. However, it is controversial whether activation of S1PR1 would enhance or attenuate pain. Here, recent studies ＜br> and current perspectives are discussed in order to better under-stand the biological and pathological roles of S1PR1 in pain mod-ulation.

Objective To understand the status of health knowledge and behaviors on clonorchiasis sinensis of urban resi-dents in Yanqing District of Beijing City,China,so as to provide the targeted suggestions for further health education. Meth-ods The communities/streets were selected as the investigation sites by using the stratified randomly sampling method. A total of 283 residents were randomly selected and investigated with the structural questionnaire designed by Beijing Center for Dis-ease Control and Prevention. The fecal samples were collected and the eggs of Clonorchis sinensis were detected with Kato-Katz technique. Results All of the questionnaires were valid. The awareness rate about clonorchiasis was 25.09％. The rates of know-ing clonorchiasis infection route,harm and prevention measures were 10.60％,9.89％and 10.60％respectively. Totally 7.07％of the residents had the habits of eating raw or undercooked fresh water fish,and 2.47％of the residents had the behavior of eat-ing sashimi. C. sinensis eggs were not found among the research objects. Conclusions The awareness rate about clonorchiasis is low among urban residents in Yanqing District. The focus of the future work is to extensively carry out the health education about clonorchiasis prevention and control and take relevant interventions.

Objective To investigate the effects of 20% lipid emulsion on plasma ropivacaine concentration and myocardial ropivacaine content in rats. Methods Sixty male pathogen-free SD rats weighing 220-270 g were randomly divided into 2 groups (n = 30 each): group A normal saline and group B lipid emulsion.The animals were anesthetized with intraperitoneal 4% pentobarbital 40 mg/kg. The femoral vein was cannulated for drug and fluid administration. ECG (lead Ⅱ) was continuously monitored. 1% ropivacainc 5 mg/kg was injected iv. A bolus of 20% lipid emulsion 5 ml/kg was then injected iv in group B, while in group A equal volume of normal saline was administered instead of 20% lipid emulsion. The animals were sacrificed at 5, 10,20, 40, 60 and 120 min after ropivacaine infusion (5 animals at each time point). Blood samples and myocardial specimens were taken for determination of plasma and myocardial ropivacaine levels by HPLC. Results Plasma ropivacaine concentration at 20 min after ropivacaine administration was significantly higher in group B than in group A. The myocardial ropivacaine concents at 5, 10 min after ropivacaine administration were significantly lower in group B than in group A. Conclusion 20% lipid emulsion infusion can bind ropivacaine and decreasee myocardial ropivacaine content thus reducing the cardiac toxicity of ropivacaine.

Objective To summarize the clinical features of pituitary carcinoma and discuss the diagnosis,treatment and prognosis.Methods Clinical manifestations,imaging,pathologic features of one case of pituitary carcinoma were analyzed and literatures about diagnosis,treatment and prognosis of pituitary carcinoma were reviewed.Results The patient manifested polyuria onset,headache and anterior pituitary dysfunction and MRI showed pituitary lesions.He had been undergone two transsphenoidal surgery in our hospital,pathologic examinations were respectively non-functioning adenomas and atypical pituitary adenoma and tumor proliferation index (Ki-67) both were more than 30％.He was recommended radiation therapy but refused.Five months later,he was diagnosed as primary pituitary gland cancer due to the tumor widespread intracranial metastasis and no other malignant lesions in body.Conclusions Primary pituitary carcinoma is a very rare tumor,mostly transformed from the invasive pituitary adenoma.It helps predict tumor proliferation and prognosis to test the level of Ki-67 index.Primary pituitary adenocarcinoma needs comprehensive treatment and the prognosis is related to the treatment response.

BACKGROUND:Previous studies have shown that continuous administration of 1×107 of bone marrow mesenchymal stem cel s can induce immune tolerance in rats undergoing kidney transplantation, but it is not yet found clinical y that curcumin exerts an on immunomodulatory effect on kidney transplantation.
OBJECTIVE:To investigate the effects of different concentrations of curcumin on bone marrow mesenchymal stem cel s-induced immune tolerance in rats after kidney transplantation.
METHODS:Rat model of kidney transplantation was made, and rat models were randomly divided into four groups:transplantation group with no treatment;bone marrow mesenchymal stem cel s group (cel group) injected with 1×107/kg bone marrow mesenchymal stem cel s via the left iliac vein (before peritoneal suture) and tail vein (from the 2nd day) for 10 days;bone marrow mesenchymal stem cel s+low/high dosage of curcumin groups (low/high dosage curcumin groups) injected intragastrical y with 2 or 10 mg/kg curcumin combined with injection of bone marrow mesenchymal stem cel s for 10 days. Transforming growth factor-β1 protein expression in the kidney tissues was examined by immunohistochemical staining. The concentrations of interleukin-2 and interleukin-6 in serum were detected by ELISA assay.
RESULTS AND CONCLUSION:After kidney transplantation, the protein expression of transforming growth factor-β1 in renal tubular epithelial cel s and renal interstitial cel s as wel as the concentrations of interleukin-2and interleukin-6 in serum were significantly higher in the transplantation group than the other groups (P<0.05). Compared with the cel transplantation group, the protein expression of transforming growth factor-β1 as wel as the concentrations of interleukin-2 and interleukin-6 reduced significantly in the low/high dosage curcumin groups (P<0.05). These findings indicate that simultaneous administration of curcumin and bone marrow mesenchymal stem cel s can effectively inhibit immune rejection reaction and improve renal function in rats after kidney transplantation.

BACKGROUND:Heat shock proteins have unique biological characteristics, and exploration of such proteins expressed in the myocardium under exercise stress has important value.
OBJECTIVE:To investigate the studies about the expression of myocardial heat shock proteins under stress condition, and analyze the expression characteristics of myocardial heat shock proteins under different stress conditions.
METHODA computer-based online retrieval was performed to find articles about the production, classification and function of heat shock proteins, as wel as the expression of myocardial heat shock proteins published from January 1991 to January 2014 in PubMed database and Wanfang databases. The key words were“heat shock protein;myocardium;exercise stress”in English and Chinese. Final y 48 relevant articles were summarized.
RESULTS AND CONCLUSION:Heat shock proteins have the immune synergy effect. Researches show that, exercise training triggers the expression of myocardial heat shock protein. Acute exercise stress leads to a variety of physiological and biochemical changes, accordingly myocardial heat shock protein wil make the corresponding expression and protect myocardial cells. Low-intensity exercise can increase the expression level of heat shock protein 72, and inhibit cardiomyocyte apoptosis. High-intensity exercise reduces the expression of heat shock protein 72, which can not effectively inhibit cardiomyocyte apoptosis and is not conducive to the myocardial protective effect. The expression of heat shock protein under moderate-intensity exercise remains controversial. Exercise-induced expression of heat shock protein may have protection effect against damage induced by exercise, moderate exercise activities play an important role in enhancing myocardial function and preventing myocardial injury.

BACKGROUND:At present, the common filing materials used to correct secondary unilateral cleft lip nasal deformity include conchae cartilage, costal cartilage, Medpor implants, expanded polytetrafluoroethylene (ePTFE), alogenic acelular dermal matrix. OBJECTIVE:To analyze the therapeutic effects of comprehensive procedures with alogenic acelular dermal matrix or ePTFE for secondary unilateral cleft lip nasal deformity. METHODS: Thirty-six patients with secondary unilateral cleft lip nasal deformity were enroled, including 19 males and 17 females, aged 15-32 years. Alogenic acelular dermal matrix (n=22) or ePTFE (n=14) was used to correct nasal base colapse deformities. Anthropometry method was employed to make measurements. Fixed-point measurement was performed based on patient's pictures before and after correction. Long-term effects of these two kinds of filing materials were analyzed and assessed objectively and quantitatively. RESULTS AND CONCLUSION: After the folow-up of 6 months, al the patients were satisfied with their results, and no infection and no exposure occurred. The treatment effect of the alogenic acelular dermal matrix group was excelent in 16 cases and good in 6 cases; there were 10 cases of excelent and 4 cases of good in the ePTFE group. The objective indicators in the two groups were al improved at 6 months after correction (P < 0.05), but there was no difference between the two groups (P > 0.05). These findings indicate that alogenic acelular dermal matrix or ePTFE is useful to correct secondary unilateral cleft lip nasal deformity.
