OBJECTIVETo explore the effect of Qingfei Huoxue Recipe (QHR) combined azithromycin in treatment of intractable pediatric mycoplasma pneumonia.

METHODSTotally 124 intractable pediatric mycoplasma pneumonia patients at our hospital were recruited in this study, and randomly assigned to the treatment group and the control group, 62 in each group. Patients in the control group took azithromycin, while those in the treatment group additionally took QHR. All patients received omnibearing systematic nursing. Therapeutic efficacy, clinical indices (such as disappearance time of cough and rales, recovery time of body temperature) , and the incidence of adverse reactions were observed.

RESULTSAfter treatment the total effective rate was 91.94% (57/62 cases) in the treatment group and 77. 42% (48/62 cases) in the control group with statistical difference (P < 0.05). Compared with the control group, disappearance time of cough and rales, recovery time of body temperature were obviously shortened in the treatment group with statistical difference (P < 0.01). There was statistical difference in the incidence of adverse reactions between the two groups [3.23% (2/62 cases) vs 38.71% (24/62 cases) , P < 0.01].

CONCLUSIONIn clinical treatment for intractable pediatric mycoplasma pneumonia, Chinese medicine combined Western medicine plus scientific and systematic nursing showed more obvious advantages with significant efficacy, which was worth spreading.

OBJECTIVE: To investigate the genetic polymorphisms of 19 STR Loci in Shandong Han population in order to provide the genetic data for paternity testing. METHODS: The genotypes of 205 unrelated individuals in Shandong Han population were typed by Goldeneye 20A kit to get the allele frequencies and population genetic parameters of 19 STR loci. Four kits, Identifiler kit, SinoFiler kit, PowerPlex 16 kit, and Goldeneye 20A kit, were compared with each other and used in the analysis of a special paternity test case. RESULTS: The population genetic parameters of 19 STR loci in Shandong Han Population were obtained. The cumulative discrimination power (CDP) and cumulative probability of exclusion (CPE) ranked from high to low were Goldeneye 20A kit, SinoFiler kit, PowerPlex 16 kit and Identifiler kit, respectively. As duo case, the result of the real case showed that Identifiler kit had no excluding loci, and none of the SinoFiler kit, PowerPlex 16 kit or Goldeneye 20A kit could exclude fatherhood. CONCLUSION Compared with Identifiler kit, SinoFiler kit, and PowerPlex 16 kit, Goldeneye 20A kit shows the higher efficiency than the others, but is not completely satisfied for duo cases.

Objective To explore the clinicopathological features, diagnosis and therapy for pancreatic mutinous noncystic adenocareinoma(MNAC). Methods Eleven MNAC cases treated in our hospital were studied retrospectively. The clinical and pathologic data were reviewed. Results Of the 11 patients, 6 were male and 5 were female. The age ranged from 47 to 76 years with average of 60. 5 years.The main complains included upper abdominal discomfort in 8 cases, abdominal mass in 1 case and jaundice in 2 cases. CA199 serum test was positive in all patients and 5-fold high above normal value in 6 cases. The preoperative radiography of MNAC was usually not specific. Tumors located in the head in 5 cases and in the body and tail of the pancreas in 6 cases. The diameter of the tumor was 4 - 11 cm with average of 6. 5 cm.All cases underwent operation, with radical resection in 2 cases. Liver or abdominal metastasis was found in 5 cases. Postoperative immunohistochemistry showed that MUC-1 was negative in all patients. MUC-2,PCNA and Ki-67 were positive in all patients. All 9 cases that were followed-up died within 5 -22 months,with an average survival time of 10 months. Conclusions The diagnosis of MNAC depends on pathology. Its prognosis is poor.

Objective To explore the clinical diagnosis and management of hepatecellular adenoma(HA). Methods Seventeen HA cases treated in our hospital from Janurary 1986 to June 2007 were studied retrospectively.The clinical and pathologic data were reviewed. Results Of 17 patients,9 were male and 8 were female with median age of 46 years.None of the female patients had a history of oral contraceptives.Most patients were agymptomatic.Preoperative liver function test and AFP serum test were normal.Preoperative imaging study yielded deftnite diagnosis in only a fraction of patients.All 17 cases underwent surgical resection and the postoperative course is uneventful.All cases were followed up ranging from 6 to 252 months.Recurrence was not found.Pathology reported atypical hyperplagia in 2 cases and with malignant transformation in 1 case. Conclusions The diagnosis of HA is exclusive and dependent on clinical data,laboratory test and radiography.HA has a tendency to malignancy.Surgery is recommended in all cases.

Objective To explore the clinicopathological characteristics as prognostic factors in patients with colorectal signet-ring cell carcinoma. Methods Clinical data of 62 patients of colorectal signet-ring cell carcinoma and 281 patients of colorectal low-differentiated adenocarcinoma were retrospectively analyzed. COX Proportional Hazards Model was used in multivariate analysis. Results Colorectal signet-ring cell carcinoma occurred more frequently in young patients and most of them located in the rectum. Gender, preoperative CEA, pathological type and liver metastasis were not statistically different from low-differentiated adenocarcinoma (X2=0.07,0.04,0.06,1.79,P>0.05).Bowel obstruction, operative modalities, tumor embolism, infiltration depth, lymph node metastasis were statistically different from low-differentiated adenocarcinoma (X2=8.96,75.1,18.5,72.0,7.44,P<0.05). Median survival time was 28 months in patients of colorectal signet-ring cell carcinoma and 49 months in patients of colorectal low-differentiated adenocarcinoma. The difference was statistically significant (X2=12.51,P<0.05). Infiltration depth, lymph node metastasis, operative modalities and postoperative adjunctive therapy were independent prognostic factors based on a multivariate analysis of the COX Proportional Hazards Model. Conclusions The biological malignancy of colorectal signet-ring cell carcinoma is higher than that of low-differentiated adenocarcinoma in colorectal carcinoma. Radical resection and postoperative adjunctive therapy were effective treatment methods.

Objective To explore the diagnosis and treatment of intrahepatic biliary cystadenoma and cystadenocarcinoma. Methods Eight patients with intrahepatic biliary cystadenoma and cystadenocarcinoma treated in our hospital were studied retrospectively. The clinical and pathological data were reviewed. Results Most of the patients had nonspecific symptoms and serum AFP level was normal. Uhrasonography and CT diagnosed correctly in 75% and 87.5% of all patients, respectively. All the 8 patients underwent resection and had no recurrence after operation except that 1 case of cystadenocarcinoma died of recurrence 3 years later. Conclusion The diagnosis of intrahepatic biliary cystadenoma and cystadenocarcinoma depends on radiography and pathological examination. Surgery is recommended to get satisfactory results.

Aim Toresearchthemolecularmecha-nisms of DADS-induced apoptosis in human leukemia K562cells.Methods Cellviabilitywasmeasuredby MTT. Levels of DADS-induced ROS were measured by 2ˊ, 7ˊ-dichlorofluorescein diacetate ( DCFH-DA) fluo-rescence. DADS-induced mRNA levels of components of the NADPH oxidase were detected by Real-time PCR. The combination of protein Rac2 and p67phox was measured by immunoprecipitation assays. Flow cy-tometry methods were used to determine the percentage of apoptosis cells. DADS-induced Rac2 levels were measuredbyWesternblot.Results TheDADS-trea-ted K562 cells showed a dose-and time-dependent de-crease in cell viability and proliferation. There was sig-nificant up-regulation of the mRNA level of components of the NADPH oxidase complex in K562 cells after treatment with 6 mg·L-1 DADS for 6 h. Western blot results revealed that, compared with the control group, there was a significant up-regulation of Rac2 protein in K562 cells treated with 5. 0 and 10. 0 mg·L-1 DADS for 24h. And Rac2 combined with p67phox in DADS-induced apoptosis in K562 cells. PMA markedly in-creased the percentage of apoptotic cells, and DPI re-duced the percentage of apoptotic cells in DADS-in-duced K562 cells. Levels of DADS-induced ROS, also showed enhancement when exposed in PMA, but there was no DADS-induced ROS production evident when exposed in DPI in DADS induced K562 cells. Conclu-sions TheseresultsindicatethatNADPHoxidaseis the main source of DADS-induced ROS production. Diallyl disulfide induces apoptosis in human leukemia K562 cells through activation of NADPH oxidase.

Background Heat shock proteins (HSPs) are highly conserved proteins that are induced in cells when confronted with a wide variety of proteotoxic stresses.HSP27 has a high degree of similarity with α-crystallin protein.The abnormality of HSP27 structure and expression are closely related to the formation of cataracts.Our previous study showed sodium salieylate has the protective effect on H2O2-induced lens damage.Objective This study was to investigate the roles of MAPK signal pathway in sodium salicylate-induced the expression of HSP27 in human lens epithelial cells (LECs) in vitro.Methods Human LECs were incubated in the fresh media containing sodium salicylate at different concentrations (0-55 mmol/L) for different times (1-5 hours) and allowed to be recovered in fresh medium without sodium salicylate for 1-24 hours with or without pretreatment with P38MAPK inhibitor (SB203580), ERK1/2 inhibitor (PD98059) and JNK/SAPK inhibitor ( SP600125). The expressions of P38MAPK, EBK1/2, JNK/SAPK, phosphorylated P38MAPK, phosphorylated ERK1/2, phosphorylated JNK/SAPK and HSP27 were detected by Western blot. HSP27 mRNA was detected by RT-PCR. The expression of HSP27 was also detected by immunohistochemistry. Results There was only weak expression of HSP27 in normal human LECs.After stimulation of 35-55 mmol/L sodium salicylate was removed and human LECs were cultured again for 6 hours,the expression of HSP27 in LECs were significantly increased ( F= 509. 953,P<0. 01). HSP27 was absent expressed in human LECs in 55 mmol/L sodium salicylate stimulation for 1-5 hours groups, but LECs were re-cultured for 3,6 hours after removed the stimulation, the expression of HSP27 was elevated (F = 452. 534, P<0. 01). Activation of P38 M APK occurred after sodium salicylate stimulation 30 minutes and 1 hour ( F = 865.68, P<0. 01). However, ERK 1/2 was expressed after sodium salicylate was eliminated for 1-6 hours ( F = 388.84, P<0. 01). JNK/SAPK was inactived by sodium salicylate. The expression of HSP27 could be down-regulated with the pretreatment of SB203580 and PD98059. Conclusion Sodium salicylatc can induce the expression of HSP27 in human (LECs) . The effects are mediated,at least in part ,through the activation of P38MAPK and ERK1/2 signaling pathway .
