AIM: To establish the quality standard for Compound Lonicera Granules. METHODS: Fructus Forsythiae was identified by TLC.Chlorogenic acid and Baicalin were determined by HPLC. RESULTS: Fructus Forsythiae could be detected by TLC. Chlorogenic acid showed a good linear relationship at a range of 0.108～0.649?g,r=0.9999. The average recovery was 100.87%,and RSD was 1.28%.The linearity of baicalin was found in the range of 0.156～1.400?g.The average recovery was 101.31%, and RSD was 0.32%. CONCLUSION: The established methods are simple,quick and good reproductive. This study provids a method for the quality control of Compound Lonicera Granules.

Objective To observe the postconditioning cardioprotective effects of atorvastatin (ATV) on ischemia-re?perfusion injury in isolated rat heart, and the role of phosphatidylinositol-3-kinase , protein kinase B(PI3K-Akt), mitochon?drial ATP-sensitive potassium (mito-KATP channel) and mitochondrial permeability transition pore (mPTP) thereof. Meth?ods Healthy male Wistar rats were randomly divided into 9 groups:ischemia reperfusion (I/R) control group, atorvastatin postconditioning (ATV) group, ATV plus PI3K inhibitor LY294002 (ATV+LY294002) group, LY294002 group, ATV plus mi?to-KATP channel inhibitor 5-hydroxydecanoate (ATV+5-HD) group, 5-HD group, ATV plus mPTP inhibitor ATR (ATV+ATR) group, ATR group and ethanol group. Model rats were given 30-min ischemia followed by 120-min reperfusion. The myocardial infarction size, hemodynamic parameters, creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH), nic?otinamide adenine dinucleotide (NAD+) and the expression of myocardial protein kinase B (Akt) and myocardial phospho-pro?tein kinase B (p-Akt) were evaluated. Results Compared with the control group, atorvastatin reduced the myocardial in?farction size, CK-MB and LDH(P<0.05), increased NAD+(P<0.05). There were no significant differences in the myocardi?al infarction size, CK-MB, LDH and NAD+between ATV+LY294002 group, ATV+5-HD group and ATV+ATR group. The hemodynamic parameters were improved in ATV group compared with those in control group. Western blot analysis con? firmed the significant phosphorylation of Akt in ATV group, ATV+5-HD group and ATV+ATR group compared with those of control group. There were no significant differences in the phosphorylation of Akt between ATV +LY294002 group, LY294002 group, ATR group and 5-HD group. Conclusion Atorvastatin postconditioning could attenuate the ischemia-re?perfusion injury through activating the PI3K-Akt, promoting mito-KATP channel opening and inhibiting mPTP opening.

Clinical immunology should display the advanced and applied characteristics of immunology,and show the speciality of clinical practice.This course is a bridge between fundamental immunology and clinical teaching so that the medicos should get better foundation for the future learning.

OBJECTIVE To explore the precaution against nosocomial fungal infections of lower respiratory tract(NFILRT).METHODS A retrospective analysis on eighty-seven cases who catched NFILRT during the years 2002 to 2004 was done.RESULTS 80.46% Cases were over 60 and the average age was 67.95 and the average in-hospital days were 46.95;most of the NFILRT patients had serious underlying diseases.Before the NFILRT,immunosuppressive agents had been injected to 47.13% cases and 42.53% patients had taken anti-acid medicine;94.25% cases had received antimicrobial agents and the average days of using antimicrobial agents were 11.01 days,and among these patients 62.20% had received more than two kinds of antimicrobial agents.About 32.18% of the NFILRT cases were associated with tracheal intubation,incision of trachea and mechanical ventilation;some patients had no clinical symptoms referred to the respiratory tract;the mortality rate was 26.44% and it couldn′t be obviously cut down by using antifungal agents.CONCLUSIONS It is very important to prevent NFILRT by using antimicrobial agents reasonably and enhancing immunity in these patients.

OBJECTIVE To know the basic situation of nosocomial infection control and management in all levels of hospitals in Anhui Province,and provide the theory basis for the future work.METHODS To investigate the students participating in the nosocomial infection management training class by using the questionnaire.RESULTS There were altogether 273 people from 217 hospitals accepting the investigation.From 217 hospitals there were 46 1st grade hospitals and 160 2nd grade hospitals and 11 third graed hospitals.In all the people engaged in the nosocomial infection management,83.88% were the females and 67.03% for nursing staff,the age of 30-50 years old was 79.84%,the middle professional rank accounted for 72.53%,and 79.86% people′s record of formal schooling was the technical college and below.CONCLUSIONS The basic situation of nosocomial infection management in majority hospitals of our Province is good,but in some hospitals,the function of the structure has not certainly obtained the full display.In order to adapt the development of the nosocomial infection supervisory work,promote it to be more perfect,personnel structure,resources arrangement,and administrative offices function should give enough reconstruction and construction.

OBJECTIVE To investigate the surgical site infection(SSI)in clean surgical sites and the perioperative antibiotic usage.METHODS The incidence of SSI and the antibiotics usages in 842 cases during perioperative were analyzed retrospectively in 32 hospitals.RESULTS One case with nosocomial infection was found(0.12%).The use rate of antibiotics was 98.57%.Among 802 cases using prophylactic antibiotics,the antibiotics were given in 181 cases thirty minutes to two hours before operation.136 cases were given 24 h before operation.And 485 cases were given after operation;195 cases stopped using antibiotics after 24 h,472 cases stopped using antibiotics after 4-6 days and 135 cases stopped to use antibiotics after 7 days.CONCLUSIONS The major problem is excessive use of antibiotic in clean surgical site during perioperation,long duration of antibiotics prophylaxis,more expensive antibiotics and unnecessary combination of antibiotics,suggesting that it be important to strengthen the management of antibiotics.

0.05);the main infection site was lower respiratory tract(61.97%),followed by surgical site infection(SSI)(23.94%).CONCLUSIONS In order to reduce postoperation nosocomial infection rate,we should take following measures:Improve pulmonary function,remove tracheal intubation as early as possible,shorten lasting time of surgery and days before operation,keep aseptic technique,strengthen nursing,enhance immunity,and use antimicrobial agents reasonably.

OBJECTIVE To understand the sites of nosocomial infection and its pathogenic bacteria. METHODS Infection sites and pathogens of 2134 patients with nosocomial infection were analyzed. RESULTS Totally 2235 infections were occurred. The main site was lower respiratory tract(30.47%),followed by upper respiratory tract(18.20%) and operated wound(12.17%). Among 815 strains,149 were Gram-positive bacteria,456 Gram-negative bacteria and 210 fungi. The rates of main Gram-positive cocci in lower respiratory tract,burned and operated wounds were 42.14%,20.00% and 12.86%,respectively; the rates of main Gram-negative rods in lower respiratory tract,burned wound and urinary tract was 44.14%,29.70% and 10.90%,respectively; the rates of fungi in lower respiratory tract,oral cavity and gastrointestinal tract was 41.90%,18.56% and 18.10%,respectively. CONCLUSIONS According to the main sites and pathogenic bacteria of nosocomial infection,countermeasure should be taken to prevent and control nosocomial infection.

Objective To evaluate the value of IgA and IgG antibodies against α-fodrin in both serum antibodies in SS is also assessed.Methods Samples from 39 patients with SS(25 primary and 14 secondary),8 patients with systemic lupus erythematosus(SLE),and 15 patients with rheumatoid arthritis (RA)as well as 10 healthy blood donors were collected.Anti-α-fodrin antibodies were measured using ELISA.Results The titer of serum anti-α-fodrin was higher in SS than in other connective tissue diseases group and healthy group(P<0.01).IgA type anti-α-fodrin antibodies was detected in 60%.44% of serum and saliva in patients with pSS respectively.IgG antibodies were detected in 43% of sera,and 29% of saliva of patients with pSS.The sensitivity and specificity of serum anti-α-fodrin IgA in SS was 54%and 85%.The level of anti-α-fodrin was positively associated with xerostomia and parotid swelling (P<0.05),and was negatively associated with xeroma,renal tubule acidosis,lung interstitial disease and hepatic damages(P>0.05).Conclusion Saliva and serLlm anti-α-fodrin level may be diagnostic for SS.It may be a useful screening marker.
