Objective To explore the clinical effect of probiotics combined with saline enema in the treatment of infantile diarrhea and its effect on serum inflammatory factors.Methods 186 cases of infantile diarrhea were selected,they were randomly divided into three groups according to the random number table method:probiotics group,montmorillonite group and control group.Patients in probiotics group were administered with clostridium butyricum combined with saline enema,and patients in the montmorillonite group were treated by montmorillonite combined with saline enema,and the control group was given routine treatment.Then,the clinical symptom relief time,total effective rate,serum inflammatory factor concentration and adverse reaction were observed and compared.Results The total effective rate of the probiotics group was 98.39%,and that of the montmorillonite group was 96.77%,both of which were significantly better than 80.65% of the control group,and the differences were statistically significant(χ2 =11.408,P =0.000;χ2 =8.432,P =0.018).After treatment,the serum levels of inflammatory factor tumor necrosis factor -α(TNF -α)in the probiotics group,montmorillonite group,control group were (8.30 ±2.33)pg/mL,(8.54 ± 2.47)pg/mL,(12.49 ±3.44)pg/mL,and the difference was statistically significant(F =5.120,P =0.014),also, the serum levels of interleukin -6(IL -6)in the three groups were (10.08 ±5.46)pg/mL,(11.24 ±5.84)pg/mL, (14.02 ±5.97)pg/mL,the difference was statistically significant(F =34.015,P =0.000).There were 2 cases of constipation in the montmorillonite group,the incidence rate was 3.23%,and there was no adverse reaction in the other two groups.Conclusion The effect of probiotics combined with saline enema in the treatment of infantile diarrhea is similar to that of montmorillonite,which can promote the children to alleviate the symptoms,shorten the length of hospital stay,reduce inflammation,and has no adverse reactions such as constipation,it is worth to be recom-mended widely for clinical application.

Objective To evaluate the effect of therapeutic touch on continuous positive airway pressure titration with obstructive sleep apnea hypopnea syndrome (OSAHS) patients.Methods Fortyeight patients diagnosed with OSAHS were randomly allocated to the therapeutic group and the control group with 24 patients in each group.Therapeutic touch was used in the therapeutic group before CPAP titration and the control group received usual care.Anxiety was measured post intervention with State-trait Anxiety Inventory(SAI) and Visual Analogue Scale(VAS).CPAP therapy satisfaction was also evaluated by VAS.Results Compared with the control group,those patients with therapeutic touch showed significant reductions in SAI scores,better sleep quality,and higher satisfaction with CPAP treatment.Conclusions Results suggest that 15-min of therapeutic touch pre CPAP titration night significantly reduced anxiety and improved sleep quality in patients with OSAHS.

Eighty-eight patients with obstructive sleep apnea hyperpnoea syndrome (OSHAS) were assigned to the mild (n =21 ), moderate (n =30), or severe group (n =37) according to apnea-hypopnea index( AHI ). Twenty-five healthy individuals were selected as normal controls. Color Doppler ultrasonography was used to measure the intimae-media thickness of the carotid coteries and the occurrence of sclerosis plagues. Our data found that increased severity of OSHAS led to the elevated intimae-media thickness of the carotid coteries and more sclerosis plagues, which suggests OSHAS may influence the development of the carotid artery arthrosclerosis.

Objective To study the pathogenesis mechanism of hepatitis C vires (HCV) core protein (CORE), the subcellular localization of different truncated genotype 1b HCV CORE was observed. Methods HepG2 cells were transiently transfected with the enhanced green fluorescence protein (EGFP-CORE) recombinant plasmids, which expresses EGFP and COREs from three different genotype lb HCV strains and different truncated COREs from one HCV strain. The localizations of different truncated COREs was analyzed by the laser scanning confocal microscope and fluorescence microscope. Results N terminal 1-172 an of different HCV strains of genotype 1b expressed mainly in cytoplasm. Among the different truncated COREs, the longer of the CORE containing N terminal, the more expressed in cytoplasm. The N terminal 1-58 aa mainly expressed in nucleus. CORE of 59-126 aa and 127-172 aa expressed both in cytoplasm and nucleus. Conclusion The different localizations of different truncated COREs might have some relationships with their functions in pathogenesis.

Objective The current study was to investigate the clinical and pathological features of macroscopic hematuria associated acute kideny injury (MH-AKI) in patients with IgA nephropathy (IgAN) and its associated prognostic factors.Methods We performed an analysis on the clinical and pathological features of biopsy-proven IgAN patients diagnosed during 2004 to August of 2007,who had experienced MH associated AKI.The patients enrolled in the study were followed up.The renal lesions were evaluated with Katafuchi pathological scores of IgAN.Results 5 patients with IgAN had experienced at least one episode of MH-AKI,accounting for 1.3% of IgAN diagnosed during the same period and 13.5% of IgAN patients with macroscopic hematuria.High proportion of tubules filled with red blood cell casts and tubular injury were demonstrated in all biopsy specimens.Renal function of 3 patients completely recovered within 14 days.One patient (patient 4) got quick recovery in the first month of the disease but completely recovered 418 days later.The other patients only had an incomplete recovery during the 20-month follow-up.The incompletely recovered one had relatively an older age,longer persistence of MH,more sclerotic glomeruli and a more severe tubule-interstitial damage.Conclusion AKI is commonly seen during episodes of MH in patients with IgAN.Not all patients with MH-AKI showed a complete recovery.Age,duration of MH,proportion of glomerular sclerosis and the severity of tubular necrosis might be the risk factors of an incomplete recovery of renal function.

OBJECTIVE:To approach the correlations of carbamazepine concentration in serum with clinical therapeutic effect,dosage,sex,age and body weight in epileptic children.METHODS:158 monitoring records for serum concentration of carbamazepine in children with epilepsy in our clinical pharmacy department were consulted retrospectively.Data such as serum concentration,sex and age were recorded into data base and were analyzed using SPSS 13.0 software.RESULTS:No significant correlation was noted between serum concentration of carbamazepine in epileptic children and sex.However,serum concentration of carbamazepine was closely correlated with clinical therapeutic effect,dosage,age and body weight.CONCLUSION:The individual difference in the metabolic processes of carbamazepine was concerned with age and body weight,so it's necessary to make individualized regime according to child's specific condition and monitoring results.
