OBJECTIVE To study the diagnostic and therapeutic conditions in a general hospital,and try to find out the measures to decrease cross infection in hospital. METHODS From Dec 2003 to Nov 2004,2 037 cases of infectious diseases were diagnosed and treated in our hospital.All these cases were analyzed. RESULTS Among the 2037 cases,the most common diseases were viral hepatitis and pulmonary tuberculosis.And others were infectious diarrhea,gonorrhea,syphilis,typhoid,paratyphoid,epidemic parotitis,bacillary dysentery,epidemic encephalitis B,measles,tetanus of newborn and rabies. CONCLUSIONS To control cross infection in hospital effectively,we must pay more attention to standardized management of infections diseases,strengthen the isolation and protective conciousness of medical personnel for infectious diseases,and tighten up the management of sterilization and isolation.

Objective To discuss nursing of patients with early severe acute pancreatitis undergoing laparoscopic treatment and in comparison with open surgery. Methods Totally 56 patients with early se-vere acute pancreatitis were admitted from October 2002 to October 2007,among which 30 cases (group A) received laparoscopic.treatment and the other 26 cases (group B) was given open surgery.The average time of hospital stay,incidence of complication and re-operation were compared between the two groups. Re-sults The average time of hospital stay,incidence of complication and re-operation of group A were lower than those of group B (P<0.05). Conclusions Treatment of severe acute pancreatitis with laparoscopy proved to be a desirable method in that it performs good effect with little trauma and low fatality.Other basic treatment,regulation of water and electrolyte balance and acid-base balance,enforcement of nutritional sup-port,fasting and gastrointestinal decompression should not be ignored.

OBJECTIVEThis study investigates the immune status of T helper (Th) 17 cells in mice with periodontitis.

METHODSSeven-week-old C57BL/6 female mice were randomly divided into the control and periodontitis groups. Each group comprisedfour mice. Experimental periodontitis was induced in mice by oral infection with Porphyromonas gingivalis in the periodontitis group. Phosphate-buffered saline solution was used in the control group. All mice were sacrificed 4 weeks after the last P. gingivalis infection. CD4⁺retinoid-related orphan receptor (ROR) γτ⁺(Th17) cells were analyzed by flow cytometry. The protein expression of Th17 cell-related cytokine interleukin (IL)-17A was detected by enzyme-linked immunosorbentassay (ELISA).

RESULTSFlow cytometry showed that the percentage of CD4⁺RORγτ⁺(Thl7) cells in all CD4⁺ cells and the cell number in gingival tissues, cervical lymph nodes (CLNs), and the peripheral blood obviously increased (P < 0.01) in the periodontitis group. ELISA showed that compared with the control group, the periodontitis group exhibited an obvious increase in the protein expression of IL-17A (P < 0.05).

CONCLUSIONTh17 cell-mediated cell response is enhanced, and the gingival tissues, CLNs, and the peripheral blood are probably the main locations of Thl7 cell-mediated cell response during the development of periodontitis.

Objective To evaluate the effectiveness of allergen specific immunotherapy (SIT) in the treatment of allergic rhinitis. Methods A total of 132 patients with seasonal ragweed allergic rhinitis were enrolled in this study. The patients were randomly divided into two groups. SIT group, in which 68 patients were treated with ragweed SIT for six months before July for 3 years. ST (symptomatic therapy) group, in which 64 patients were treated with ST during seasonal symptomatic period. The healthy control group included 40 subjects. The levels of serum total IgE (tIgE), specific IgE (sIgE), ECP, IgG and IL-4, IL-5, IFN-? were measured, and eosinophil numbers were counted. The symptom score, lung-function test and skin prick test were performed before and after the treatment. Results The elevated levels of tIgE, ECP, IL-4, IL-5 in the sera and eosinophil counts in peripheral blood of the patients were significantly reduced, whereas the levels of IgG and IFN-? were increased following SIT. The levels of serum sIgE were not changed in both SIT and ST groups. 30.88% of the patients were clinically cured, the effective rate was 41.18%, the improvement rate was 20.59% after SIT, and only in 7.39% of patients there was no clinical improvement. In 16.18% of patients there were mild side effects to SIT. In the ST group, there was on change in all the laboratory results and clinical symptoms, and 25% of the patients developed asthma. Conclusion SIT was able to improve the symptoms and laboratory results of the patients with allergic rhinitis. The results indicated that SIT may be an effective and safe therapy for patients with allergic rhinitis.

Objective To establish an HPLC method for determination of matrine in matrine ethosome thermosensitive gels. Methods Matrine was detected in matrine ethosome thermosensitive gels by using a YMC-Pack NH2 column(4.6 mm× 150 mm,5 μm),with the mobile phase containing acetonitrile-ethanol(9: 1).The flow rate was 0.8 mL·min-1 ,the column temperature( 25 ± 2) ℃ and the UV detection wavelength 215 nm. Results The peak area correlated with matrine concentration within the range of 1.00-100.00 μg·mL-1 linearly,and the average correlation coefficient was 0.999 2.The average recoveries rate of low,medium and high concentration of matrine were 98.16%,98.15%,98.00%,respectively,and the RSD were 0.30%,0. 69%,0. 71%,respectively. Conclusion The method is simple,sensitive and accurate. With the advantages of specificity,high precision,good stability and repeatability,the HPLC method can be used for the determination of matrine in matrine ethosome thermosensitive gels.
