Objective:To explore the clinical effect ofpaishitang combined with tamsulosin hydrochloride on the patient with up per urinary calculi after extracorporeal shock wave lithotripsy (ESWL).Methods:120 cases with upper urinary calculi in our hospital from January 2015 to September 2016 were selected and divided into two groups according to the random number table,60 cases in each group.ESWL was given to both groups of patients and provided with tamsulosin hydrochloride postoperation,then paishitang were additionally given to the patients in the observation group.The clinical effect and changes of serum creatinine (Scr),neutrophil gelatinase as sociated lipocalin (NGAL),cystatin C (Cys-C) and glomerular filtration rate (GFR) levels before and after treatment were compared between two groups.Results:The total effective rate of observation group was 96.67％,which was 86.67％ in the control group,no signifi cant difference was found in the total effective rate between the two groups(P＜0.05).The stone discharge rate was 95.00％ in the observation group,which was significantly higher than that of the control group (P＜0.05);the incidence rate of renal colic was 6.67％,which was significantly lower than that of the control group(P＜0.05),the stone discharge time and the duration of hematuria were significantly shorter than those in the control group (P＜0.01).There was no significant difference in the recurrence rate between the two groups within one year (P＞0.05).The serum NGAL and Cys-C levels of both groups were gradually increased while the GFR levels were gradually decreased on the 1st,2nd day postoperation,but all the index mentioned above gradually recovered on the 3rd day postoperation.The levels of NGAL and Cys-C in the observation group were significantly lower than those in the control group on the 1st,3rd day postoperation while the GFR was significantly higher in the observation group than those of control group on the 1st,3rd day postoperation(P＜0.01).No significant difference was found in the Scr at different time points postoperation between two groups(P＞0.05).Conclusion:Paishitang combined with tamsulosin hydrochloride had significant clinical effect on thpatient with upper urinary calculus after ESWL and could effectively improve the renal injury induced by ESWL.

BACKGROUND: The quantity and bioactivity of isolated islet are vital to islet transplantation; while, the cold ischemia time and human leucocyte antigen (HLA) typing are key factors to islet quantity and bioactivity which inflect islet transplantation.OBJECTIVE: To observe the effects of cold ischemia time and blood compatibility on quantity and bioactivity of islet cells.DESIGN: Observational study.SETTING: Ruikang Affiliated Hospital of Guangxi College of Traditional Chinese Medicine.MATERIALS: Organs from voluntary donors died of irreversible coma were adopted whose blood-type and HLA typing had been known, pancreases acquisition was carried on after other organs ablation or in the meantime. The blood of identical ABO and HLA matching conformity, or HLA cross-matching hypersensitization (missmatching over 3 Iocuses),or panel reaction antibody (PRA) ＞ 50%, or lymphocyte cytotoxin crossmatching test positive. The isolated and purified islet suspension was filtered by 70 μm filter, which result in preparing 1.2×105/L islet suspention.METHODS: Hypertonic citrate adenine solution was perfused into aorta, and kidney-pancreases and kidney-pancreases-liver were cut together or kidney-pancreases-liver was cut separately. Islet activity was judged by diphenylthiocarbazone (DTZ) dyeing and acridine orange (AO) dyeing; meanwhile, twelve pancreases far from contamination were aquired, mean ablation time was 15 minutes; cold ischemia time ranged from 2.5 to 8 hours. Cold ischemia time of nine pancreases was controlled in 5 hours, warm ischemia time was 0-3 minutes, and peptic time was (15±2.4) minutes, correlation of islet cells and histocompatibility with survival of islet cells was analyzed.MAIN OUTCOME MEASURES: Survival rate of islet cells; counts of platelet, heterophil granulocyte and monocyte.RESULTS: The cutting of kidney, pancreases and liver were successful. If the cold ischemia time was controlled within 5 hours, activity of islets was above 80%. Pancreatic gland used for islet transplantation and cutting of other organs could not affect activity of islet cells. When human islets were exposed to human blood, it would induce a rapid consumption of platelets, neutrophils, monocytes and lymphocytes in the blood. Consumption of blood cells was more in the HLA typing groups than that in the control group. After adding heparin, there was significant difference in cell account among the three groups (P ＜ 0.05) and the reaction was relieved obviously. After 24-hour cultivation, there were significant difference in active islets quantity between HLA typing compatibility group and HLA typing incompatibility group (P ＜ 0.05).CONCLUSION: Pancreatic gland obtained under the cold ischemia time ＜ 5 hours can be used in clinical transplantation of islet cells; a good histocompatibility can raise successful rate of transplantation of islet cells.

BACKGROUND: The incompatible reaction may occur after islet transplantation, which affects the survival and functions of cells. OBJECTIVE: To explore the islet cells injury and its causes during islet transplantation. METHODS: The pancreases of voluntary, brain death, donors were isolated by collagenase, and the islet cells injury was measured with different cold ischemia times. The islet cells were cultured with blood as follow: HLA matching group: recipient whole blood + islet cells, recipient whole blood + islet cells + heparin; HLA mismatching group: recipient whole blood + islet cells, recipient whole blood + islet cells + heparin; Control group: recipient whole blood + RPMI1640. The potential injury to islet cells was observed. RESULTS AND CONCLUSION: The pancreases were smoothly obtained. The activity of islets may be more than 80% within 5 hours of ischemia preservation time, which was less than 19% if the cold ischemia preservation time was over 8 hours. When human islets were exposed to human blood, it will induce a rapid consumption of blood cells, no matter HLA matching or HLA mismatching. After adding heparin into the blood, these events were avoided. At 24 hours of in vitro culture, the number of survival islet cells in the HLA matching group was greater than that of the HLA mismatching group (P < 0.05). The results described that cold ischemia time affects islet cells activity, reduce the cold ischemia preservation time within 5 hours and HLA typing are conductive to enhance the quantity of living islets.

OBJECTIVE To study the electrophysiological character of the Auditory Brainstem Response to Speech Sounds (s-ABR) in healthy adults. METHODS We assessed the auditory brainstem response to a synthesized stop-consonant speech syllable /da/ in 40 native-Chinese speech adults (20 female). Timing components of the response were compared between males and females to determine the relationship between inducing rate ,latency of waves and sex and age of participants. RESULTS The latency of wave V and A was shorter in females was that of males (Vt(38)=-3.601, P =0.001, At(38)=-2.829, P=0.007).The other peaks latency except V、A can see difference between gender but do not have statistics differences (P>0.05); The latency has no statistical difference in different age (P>0.05); The amplitude has no statistical difference in different gender and age (P>0.05). CONCLUSION The waves of s-ABR has good stability for studying mechanism of auditory speech processing tools.

BACKGROUND:It has great significance to understand individual human leucocyte antigen allele(HLA) haplotype and genotype in organ allotransplantation.OBJECTIVE:To analyse HLA allele frequency,haplotype frequency and characteristices in 36 cases of living-related donor kidney transplantation.DESIGN,TIME AND SETTING:The gene polymorphism analysis was performed in the Tissue Typing Laboratory of Organ Transplantation of Ruikang Hospital of Guangxi Traditional Chinese Medical University from January 2007 to June 2008.PARTICIPANTS:Thirty-six cases of living-related donor kidney transplantation,who were relatives of Guangxi Han population.METHODS:HLA-Ⅰantigen was detected by dry plates of monoclonal antibodies,and HLA-Ⅱ antigen was subjected to genotyping using PCR-SSP technique.And then the allele and haplotype frequencies of HLA-A,B,DRB1 were calculated.MAIN OUTCOME MEASURES:HLA haplotype and genotype of Guangxi Han population.RESULTS:A total of 11 HLA-A,24 HLA-B and 13 HLA-DR alleles were detected among 36 cases,showing a rich polymorphism.A2-B46,A11-B60,B46-DRB1*09,B60-DRB1*15 and A2-B46-DRB1*09 among 144 haplotypes were informative with frequency higher than 0.05.A total of 10 HLA-A-B haplotypes and 9 HLA-B-DRB1 haplotypes were in strongest linkage disequilibrium.Distribution of HLA-A,B,DRB1 alleles and haplotypes in Guanxi population is similar to Han population in South China,such as Hunan and Taiwan,but had its own characteristics.CONCLUSION:HLA alleles have richer polymorphisms with exhibit geographic genetic characteristics.

Objective To investigate the characteristics of auditory nerves and brainstem pathways,patho-physiological and nerve damages and the correlation between oxygen indexes,and the values of high stimulation ABR in patients with OSAHS.Methods Auditory brain stem responses (ABR)at rates of 11.1 times/s,31.1 times/s,51.1 times/s were performed in both the moderate-to-severe OSAHS group(5 cases of moderate and 34 cases of severe,in total of 39 cases ,78 ears)and the control group (34 cases,68 ears).According to the character-istics of ABR,the correlation with parameters of blood oxygen was studied.Results At the rate of 11.1 times/s, wave V latencies (5.79±0.22 ms)in OSAHS patients were longer than that in the control group.At the rate of 31.1 times/s,wave V latencies (5.98±0.19 ms)and waveⅠ(1.85±0.18 ms)in OSAHS patients were prolonged more than those in the control group.At the rate of 51.1 times/s,wave V latencies (6.09±0.25 ms)and waveⅠ(1.94±0.26 ms)in OSAHS patients were longer than those in the control group.Increasing stimulation rates from 11.1 times/s to 31.1 times/s showedΔⅠwas longer in OSAHS group(0.12±0.17 ms)than in the control group (0.07±0.11 ms).Increasing stimulation rates from 11.1 times/s to 51.1 times/s showedΔⅠwas longer in OS-AHS group(0.21±0.25 ms)than in the control group(0.15±0.10 ms).All above had correlations with hypoxia. Conclusion High stimulation rates in ABR by amplifying the waveⅠ latency confirm cochlear and auditory nerve damages near the cochlear segment in patients with moderate to severe OSAHS.Therefore the study of nerve injury in OSAHS patients should take blood oxygen saturation and hypoxia percentage rather than AHI.

Objective To evaluate the appearance of CT in patients with severe acute respiratory syndrome (SARS) in the recovery phase, and to study the correlation of CT findings with pulmonary function.Methods From June to August in 2003, 100 patient with confirmed SARS accepted examination in our hospital. Among them, 91 patients (39 men, 52 women, mean age 36.4 years, age range 19- 66 years) received CT examination and pulmonary function test on the same day. The interval between SARS onset and the examination ranged from 52 to 125 days (mean 87.4 days). CT appearances of pulmonary parenchymal abnormalities including distribution and extent of involvement were quantitatively analyzed, and four levels on CT scan including the aortic arch, the tracheal carina, the pulmonary venous confluence, and the dome of right diaphragm were selected to score the lesions. The correlation of CT scores with the results of pulmonary function tests was studied.Results Of the 91 cases, 47 patients had normal CT appearance in the recovery phase, whereas the other 44 patients still had parenchymal abnormalities, including residual ground-glass opacification and reticular shadow. CT visual score had correlation with DLco% ( r =-0.618, P

Objective To investigate the protective effect and mechanism of serum containing Euonymus fortunei on the rat pancreatic islet cells. Methods Forty male SD rats were randomly divided into 5 groups (n=8 in each group), including the control group (normal rat islet cells were cultured with normal rat serum), ischemic preconditioning group (abdominal aorta was blocked first and then re-opened before the pancreas was obtained, and the pancreatic islet cells were cultured with normal rat serum), Euonymus fortunei treatment group (normal rat islet cells were cultured with rat serum containing Euonymus fortunei), Euonymus fortunei group and blank group (normal rats were administered orally with Euonymus fortunei extract or distilled water for the preparation of rat serum). Diphenylthiocarbazone (DTZ) staining was utilized to observe and calculate the quantity of islets. Acridine orange (AO)/propidium iodide (PI) staining was adopted to calculate the survival rate of islet cells. The insulin release experiment was performed to calculate the stimulation index (SI) and evaluate islet cell function. The concentration of glutathione (GSH) and nitric oxide (NO) in islet cells was detected using GSH and NO kits. The expression level of inducible nitric oxide synthase (iNOS) messenger RNA (mRNA) was quantitatively measured by reverse transcription polymerase chain reaction (RT-PCR). Results Islet cells were observed in specifically scarlet color after DTZ staining. The quantity of islet cells did not significantly differ among different groups (all P>0.05). Along with the prolongation of culture time, the activity of islet cells in each group was gradually decreased. At 72 h after isolation and culture, compared with the control group, the survival rate of the cells was significantly higher in the Euonymus fortunei treatment group (P<0.05). The insulin release test results demonstrated that compared with the control group, the SI of the ischemic preconditioning and Euonymus fortunei treatment groups was significantly increased (both P<0.05). Compared with the control group, the GSH contents of pancreatic islet cells in the ischemic preconditioning and Euonymus fortunei treatment groups were considerably enhanced, the NO content was significantly decreased, and the expression level of iNOS mRNA was significantly down-regulated (all P<0.05). Conclusions Euonymus fortunei can increase the survival rate of islet cells and enhance the function of pancreatic islets by increasing the level of GSH, down-regulating the expression of iNOS and decreasing the NO production.
