The mammalian target of rapamycin (mTOR) disorders have a close relationship with autoimmune disease,tuberous sclerosis (TfSC),cancer,obesity and senescence.mTOR inhibitors are wildly used in pediatric renal transplantation and TSC.Growth is an important indicator of children health and safety evaluation of pediatric drugs must include impact on growth.No evidence showed mTOR inhibitors had side effect on growth in children.

OBJECTIVE To investigate the clinical and etiology characteristics of nosocomial pneumonia. METHODS Patients with nosocomial pneumonia from Jan 2003 to Nov 2003 were chosen to be analyzed. RESULTS There were 241 patients with nosocomial pneumonia,the incidence rate of the nosocomial pneumonia in nosocomial infection patients was 41.77%,and the incidence rate of males was much higher than females(1.87∶1),and it was 43.15% in old person among patients with nosocomial pneumonia which was much higher than others,58.72% patients began to have the symptoms in the first 20 days from the day they accessed the hospital,the incidence rate of patients who had been treated by one antibiotic or two antibiotics combination,Immunosuppressors or glucocorticoids drugs were all higher than 50%,the incidence rate of patients who treated by radiotherapy,chemotherapy,thorax-abdomen operations,tracheotomy and ventilator were also quite high,the main pathogens were Gram-negative bacilli(63.95%). CONCLUSIONS We should make heavier prevention and treatment measures in front of target population and their high risk factors and the related rings,so that we can get the real effects.

OBJECTIVE To compare the detection rates of Ureaplasma urealyticum(Uu),by 4 kinds rits and find out the best one.METHODS Using four kinds of mycoplasma detection kits,namely are French mycoplasmaIST2,Zhuhai Livzon′s ICS,Dark horse′s IES and Shanghai Its Prachanda,under the same conditions,the mycoplasma of the Clinical specimens for 260 cases were tested.RESULTS The detection rate of mycoplasma(Uu) for 48 hours by four kinds of brands kits about mycoplasma liquid culture was as follows 45.4% for French MycoplasmaIST2,36.2% for Zhuhai Livzon′s ICS,37.7% for Dark horse′s IES and 36.8% for Shanghai Its prachanda.The results of susceptibility test: the reagent of IST2 had.the lowest resistance to josamycin,doxycycline,clarithromycin,ofloxacin and azithromycin,and had the better results than the other three kinds of reagents.Mycoplasma reagents form different companies had significant differences in resistance rates to five kinds of antibiotics.CONCLUSIONS The results suggest that when we cultivate clinical mycoplasma should be careful to select of the mycoplasma liquid culture identification kit.

Objective To investigate the effect of Yangyinqingfei granula on immune function in the treatment of mycoplasma pneumonia complicated with Epstein-Barr virus of children.Methods 108 mycoplasma pneumonia complicated with Epstein-Barr virus of children from our hospital were selected and randomly divided into two groups.The control group of 54 cases were treated by simple western medicine treatment and the experimental group of 54 cases were treated on the basis of the control group with Yangyinqingfei granula.The improvement of clinical symptoms, inflammation indexes and the levels of T lymphocyte subsets, clinical efficacy and complications were compared.Results The clinical efficacy in experimental group was 90.74%,which was significant higher than that in control group 75.93%(P <0.05).Compared with the control group,the remission duration of fever, cough and rales,the disappearance time of lung X-ray,the length of stay were shorter(P<0.05), the CRP,IL-6,TNF-αand IL-8 levels were lower ( P <0.05 ) , the CD3 +, CD4 +, CD4 +/CD8 + and NK levels were higher, the CD8 +level was lower ( P <0.05 ) . Conclusion Yangyinqingfei granula could reduce the inflammatory factors and improve immune function in the treatment of mycoplasma pneumonia complicated with Epstein Barr virus infection pneumonia in children.

AIM: To establish a HSP90 highly expressing cell line and study the effect of high level of HSP90 on cell stress response. METHODS: The recombined plasimid pSmycHSP, which contains the full length DNA coding for human HSP90?, was introduced into mouse fibroblast cell line NIH-3T3 by electroporation after being subcloned, purified and identified by limited enzyme digestion. Screened by G418, the positive clones were selected and identified by immunofluorescence, immunocytochemistry and Western-blotting. NIH-3T3 cells transfected with empty plasmid served as control, hyperthermia(44 ℃, 20 min, 40 min)was used to simulate oxidative stress. The activity of lactate dehydrogenase (LDH) in supernatant and damage of DNA were detected by automatic biochemistry analyzer and flow cytometer separately to analyze the effect of high-level HSP90 on cell membrane and DNA injuries under stress condition. RESULTS: The rising level of HSP90 was shown by immunofluorescence, immunocytochemistry and Western-blotting in HSP90 overexpressing cell line. There was no difference in the leakage of LDH between HSP90 overexpressing cell line and control, but the damage of DNA was more severe at 44 ℃for 20 min in HSP90 overexpressing cell line than control. Compared with control, the above indices were relieved at 44 ℃ for 40 min in HSP90 overexpressing cell line. CONCLUSION: The NIH-3T3 derived cell line, which stably expressed high level of HSP90, was established. The effect of high-level HSP90 on cells is complex at different intensity of stress, and the protection may be shown at more severe stress circumstance.

Objective To evaluate the expressions and roles of survivin (SVV), bcl-2 and proliferating cell nuclear antigen(PCNA) in cutaneous squamous cell carcinoma (SCC). Methods The expressions of SVV, bcl-2 and PCNA were investigated by SP immunohistochemistry technique in 82 cases of SCC and 18 normal skin samples. Results There were 79.3% of SCC patients with the expression of SVV (P

OBJECTIVE:To further exploit the active components from Loquat leaf and its gruffs.METHODS:The chief components in loquat leaf and its gruffs were extracted by ultrasound extraction and Soxhlet extraction,respectively,the sepa?ration of ursolic acid and other constituents was performed by HPLC,and the relative amounts of which were determined and compared.RESULTS:Soxhlet extraction is superior to ultrasound extraction in the extraction of loquat leaf and8components in gruffs.Under the same extraction method,the content of ursolic acid in loquat leaves is equivalent to that of gruffs.Besides,the contents of6components in gruffs were above those in loquat leaves.CONCLUSION:The essential component-triterpenic acid in loquat leaves suffered no loss after extraction with water,the active components in gruffs can be further exploited.

Objective To elucidate the effect of early enteral nutrition support(ENS) for the patients with severe acute pancreatitis(SAP).Methods Fifty patients with SAP were at random divided into two groups: enteral nutrition group(EN group, 25 cases), parenteral nutrition group(PN group, 25cases). PN group was given total parenteral nutrition(TPN),125 kJ/(kg?d) of energy, nitrogen intake:0.20g/(kg?d). In EN group, the naso intestinal tube was placed posterior to ligament Treitz. Since the 1st day nutrilion was infused.Results On the first?4th day, the serum RBP?PA levels were obviously decreased (P

Objective To investigate surgical treatment methods of the patients with severe acute pancreatitis complicated pancreatit necrosis (IPN) and pancreatic abscess (PA). Methods The operation of removing pancreatic abscess,infected necrosis tissues in the pancreas and peripancreatic tissues were performed. Additional, abdominal cavity infusion and drainage also were performed.Results 12 patients with IPN and 3 patients with PA were cured. Four times of operation was performed in a paitents with IPN and his corpus vertebras are infected and destructed. Another patients was relapsed after 1 year and was again performed 2 times of operation. The patient is in the stage of recovery.Conclusions IPN and PA are severe complications of severe acute pancreatitis. If image examination were showed that hydrops could not be extincted in the pancreas and peripancreas, operative therapy should be performed.
