Objective To study the therapeutic effects and mechanism of Sodium Fendate(SF) on rats with severe acute pancreatitis(SAP) induced by L-arginine. Method A total of 60 adult SD rats were randomly and e-qually divided into control group, SAP group and SF group, with 20 rats in each group. The rat model of SAP wes established by injecting 2.5 g/kg L-arginine at a dose of intraperitoneally twice at an interval of 1 hour, and rats in SAP group and SF groups were administrated intraperitoneally with 20% L-arginine solution(2.5 g/kg×2) twice at an interval of 1 hour; rats in control group were injected intraperitoneally with the same volume of physiological saline twice alone.At 5 minutes after L-arginine administration,rats in SF group were injected with SF solution (100 mg/kg, qd×3 d) via the tail vein, and rats in the other two groups received a sham injection of the same volume of physiological saline alone. The characteristics of ascites, the pathological changes of pancreatic tissue and the serum levels of amylase(AMY), endothelin-l(ET-1), tumor necrosis factor-α(TNF-α), interleukin-6(IL-6) and the contents of malonaldehyde (MDA), suede dismutase (SOD), reduced glutathioue (GSH) of pan-creatic tissue of rats and prognosis were compared at 72 hours after L-arginine administration. Measurement data were evaluated by oue-way ANOVA, and numeration data were assessed by Fisher' s exact test. P<0.05 was considered statistically significant. Results Compared with control group,at 72 hours after L-arginine administra-tion,rats in SAP group presented characteristically histopathological changes of SAP with significantly higher serum levels of AMY, ET-1, TNF-α, IL-6 and MDA of pancreatic tissue[(9715.5±301.3) IU/L vs. (729.2±134.2) IU/L;(25.32±3.67) ng/L vs. (14.32±2.69) ng/L;(102.95±11.24) ng/L vs. (38.62±3.87) ng/L; (538.63±9.53) ng/L vs. (186.35±1.19) ng/L;(34.8±3.9) mol/kg vs. (8.1±2.1) mol/kg, all P< 0.01], and lower GSH and SOD in the pancreatic tissue[(7.1±0.6) mg/kg vs. (16.9±1.9) mg/kg; (6423± 1978) kU/kg vs. (29905+2945) kU/kg,both P<0.01].Compared with SAPmodel group,at 72 hours after ad-ministration of L-arginiue, the pathological lesions of SAP in rats of SF group were significantly alleviated with lower pathological scores (P<0.05), lower serum levels of AMY, ET-1 ,TNF-α,IL-6 and MDA in the pancreatic tissue [(8104.6±149.9) IU/L vs. (9715.5±301.3) IU/L; (20.26±5.86) ng/L vs. (25.32±3.67) ng/L; (84.19±15.14) ng/L vs. (102.95±11.24) ng/L;(458±5.37) mol/kg vs. (538.63±9.53) rig/L;(28.3±2.5) moL/kg vs. (34.8±3.9) mol/kg,all P<0.05], and higher SOD and GSH in the pancreatic tissue[(8.5 ±1.4) mg/kg vs. (7.1±0.6) mg/kg;(10 316±2810) kU/kg vs. (6423±1978) kU/kg, both P<0.05].At 72 hours the death rate in SF group was lower than that in SAP group,but the difference had no significance (P= 0.2.5). Conclusions SF can scavenge oxygen-derived free radicals, upgrade the contents of SOD and GSH of pancreatic tissue,decrease the levels of serum proinflammatory cytokines and ET-1, ameliorate the pathological le-sions of pancreatic tissue in rats,and has the capability of decreasing death rate, so it possesses a distinct advantage for the treatment of SAP.

OBJECTIVETo investigate the correlation between the pathogeneses of diarrhea-pre- dominant irritable bowel syndrome (D-IBS) complicated functional dyspepsia (FD) patients of Gan-stagnation Pi-deficiency Syndrome (GSPDS) and symptoms, psychological states, and gastrointestinal hormones.

METHODSA total of 111 patients with confirmed D-IBS complicated FD of GSPDS were recruited as the treated group by using Rome III standard and Chinese medical syndrome standard. And 30 healthy volunteers were recruited as the control group. The general condition, scoring for digestive symptoms, and the distribution of GSPDS subtype of all subjects were recorded by a questionnaire, and assessed by Symptom Checklist (SCL-90; a software for psychological test developed by Beijing Huicheng Adult Cor- poration). Meanwhile, plasma levels of 5-hydroxytryptamine (5-HT), somatostatin (SS), vasoactive intestinal peptide (VIP), endothelin (ET), interleukin 10 (IL-10), and interleukin 12 (IL-12) were measured in all subjects.

RESULTS(1) The subtype of D-IBS complicated FD of GSPDS was dominant in Pi-qi deficiency type (51/111,45.9%),Pi yang deficiency type (34/111,30.6%), and GSPDS. There was no statistical difference in the scoring of digestive symptoms among the 3 subtypes (P >0.05). (2) Compared with the control group, the anxiety factor score and the total score significantly increased in all three subtypes of D-IBS complicated FD of GSPDS, and the depression score of Pi yang deficiency type and Gan-depression type also significantly increased (P <0.05, P <0.01); the depression score of Gan-depression type was significantly higher than that of the Pi-qi deficiency type (P <0.01). Plasma 5-HT levels were obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities, and VIP and IL-10 levels were significantly lower than those in the control group (P <0.05). Plasma VIP levels were also obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities (P <0.01), and SS levels were significantly lower than those in the control group (P <0.05). There was no statistical difference in plasma ET or IL-12 levels in each patient group, when compared with the control group (P >0.05). (3) Compared with the.control group, plasma 5-HT levels significantly increased, plasma VIP and IL-10 levels significantly decreased in ach subtype of D-IBS complicated FD patients of GSPDS (P <0.05, P <0.01), and no significant change of SS, ET, or IL-12 occurred (P >0.05). Besides, plasma 5-HT levels were significantly higher in Gan-depression type than in Pi yang deficiency type, VIP levels were lower in Gan-depression type than in Pi-qi deficiency type (all P <0.05).

CONCLUSIONSGan stagnation and Pi deficiency were dominant in D-IBS complicated FD patients of GSPDS. Psychological abnormalities, increased plasma 5-HT levels, and decreased plasma VIP levels were closely correlated with Gan stagnation subtype, which provided some reference for looking for objective indicators of Chinese medical syndromes in treating D-IBS complicated FD patients of GSPDS.

Objective To study the effect of Chinese herbs on human scalp hair growth in vitro. Methods Organ culture of human scalp hair follicles was used to study the effects of extracts of Crataegus cuneata, Ligustrum lucidum, Polyporus umbelatus and Bletilla striata mixture and ginseng saponin on hair growth. Results Low doses of mixture extracts(1.28 ?g/mL and 6.4 ?g/mL) markedly enhanced the hair growth and lengthened the period of hair growth, while high doses of mixture extracts(4 mg/mL and 20 mg/mL) sharply inhibited hair growth and shortened the period of hair growth. High doses of ginseng saponin (40 ?g/mL and 200 ?g/mL) also had an inhibiting effect on hair growth. Conclusion This observation suggests that extracts of Crataegus cuneata, Ligustrum lucidum, Polyporus umbelatus and Bletilla striata mixture can promote hair growth in vitro.

Objective To study transmission characteristics of Acinetobacter baumannii (A.baumannii )clone and clinical features of infected patients in a respiratory intensive care unit (RICU),so as to guide the effective pre-vention and control of A.baumannii transmission.Methods 40 A.baumannii strains isolated from RICU patients were performed homology analysis by pulsed-field gel electrophoresis (PFGE)and cluster analysis,relationship of strains was determined,antimicrobial resistance and clinical data were analyzed.Results 40 A.baumannii strains were divided into 11 genotypes(A-K),the main epidemic strains were type A,B and E.The resistant rate to imipen-em was the lowest(70.00%),the next was levofloxacin (77.50%).The average age of 40 infected patients was 67 years old,the average length of hospital stay was 41 days,12 patients died because of invalid treatment.There was overlapping hospitalization among patients infected with type A and E strains;among patients infected with type B strain,there was no overlapping hospitalization among the last 6 and first 6 infected patients.Conclusion The main epidemic strains of A.baumannii were type A,B and E,antimicrobial resistant rate is high;the infected patients are with high average age and long length of hospital stay.It is important to reduce the transmission of A.baumannii through rational use of antimicrobial agents,strict aseptic operation,and intensified disinfection and sterilization of hospital environment and medical devices.
