OBJECTIVE: To investigate effect and safty evaluation of stellate ganglion catheter retention with discontinuous block on sudden deafness. METHOD: One hundred and twenty-six patiens with sudden monaural deafness were randomly divided into Catheterp and block and control groups with 42 cases in each group. All patients' throats were given conventional blood activating drugs, hormone and hyperbaric oxygen therapy. stellate ganglion puncture retained catheter were administrated to the patients in catheter group followed by ropivacaine block 1 times/day, block group stellate ganglion puncture and ropivacaine block 1 times/day. The patients in control group were only received routine comprehensive treatment. Patients in both catheter group and block groups were treated by hyperbaric oxygen therapy after the block treatment. Curative effects of three groups were observed. The patients' satisfaction, heart rate, the chages of blood pressure before and after the block, detachment of tubes, and adverse drug reaction were recorded. RESULT: The effect of the treatment in both catheter group, block group was better than in control group (85.7%, 37 cases); 83.3%, 35 cases) vs 64.3%, 27 cases, P < 0.05). The satisfactory rate in the patients in catheter group was significantly higher than block group (83.3%, 35 cases vs 61.9%, 26 cases, P < 0.05). The heart rate and the blood pressure before and 5 minutes after catheterization in catheter group and block groupwere changed obviously. Moreover, no adverse drug reaction and detachment of tubes were observed. CONCLUSION It is a safe and effective administration of stellate ganglion catheter retention with interrupted ropivacaine block.

Objective To established cardiac-specific transgenic mice of the cTnC D145E and cTnCG159D and compare the HCM and the DCM.Methods The cTnCD145E and cTnCG159D were generated by site-directed mutagenesis and the transgenic plasmids were constructed by insertion of the mutant genes under the control of α-MHC, which is a myocardium specific promoter.The transgenic mice were generated by microinjection and were all maintained on a C57BL/6J genetic backgroud .The cardiac structure and function of the transgenic mice were compared and analysized by echocardiographic and pathological observation at different ages .Results The cTnCD145E and cTnCG159D transgenic mice were established and developed to HCM and DCM, respectively, with aging.The left ventricular end-systolic volume (ESV) and left ventricular end-diastolic volume ( EDV) decreased and ejection fraction ( EF) and left ventricular end-systolic posterior wall thickness (ESPWT) increased in the cTnCD145E transgenic mice, while EDV and ESV increased and EF and ESPWT decreased in the cTnCG159D transgenic mice at 12 months of age.Conclusions Cardiac-specific human cTnCD145E transgenic mice showed HCM phenotypes , and cardiac-specific human cTnC G159D transgenic mice showed DCM phenotypes , which can be used as different models for comparative study of the pathogenesis of cardiomyopathy .

Objective To develop a model that could copy the pathological development of psoriasis, the triple-transgenic mice that harboring Plasminogen activator, urokinase ( PLAU) ,PLAU receptor ( PLAUR) and signal transducer and activator of transcription 3 ( STAT3 ) were generated.They are the important genes involved in the pathological development of psoriasis.Methods The transgenic plasmid was constructed by insertion of the PLAU, PLAUR and STAT3 into the downstream bovine keratin 5 promoter respectively.The transgenic mouse was produced by microinjection and the genotyping was detected by PCR.The expression level of the transgenic gene was determined by Western blotting.The pathological changes were observed by HE staining.Results One mouse line was selected with over expression of the PLAU, PLAUR and STAT3 in the tissue of skin.The transgenic mice showed decreased dermal layer, a hyperkeratinized cuticular layer and increased stratum spinosum.The number of hair follicle was reduced and developed abnormally in the transgenic mice.The Munro abscess in the dermal layer and the increased inflammatory cell infiltrates in dermal layer were also observed in the transgenic mice.Conclusions A transgenic mouse line was produced and passage stably, which expressed the PLAU, PLAUR and STAT3 in the tissue of skin and developed the psoriasis progressively.All of our results suggested that the transgenic mice were a useful animal model for psoriasis.

Objective To investigate the immunophenotype and molecular genetics of mature aggressive B-cell lymphomas in Chinese pediatric patients and provide the criteris for the diagnosis of them.Methods We collected 97 paraffin-embeded tissue samples of pediatric cases of mature aggressive B-cell lymphomas including 81 Burkitt lymphoma (BL) cases, 8 diffuse large B cell lymphoma (DLBCL) cases and 8unclassifiable B cell lymphoma with featares intermediate between BL and DLBCL (BL/DLBCL) cases. The immunophenotype and genetic features of them were detected by immunohistochemistry and interphase FISH.Results The expression of bcl-2 [3 %(2/66) in BL, 50 % (4/8) in DLBCL, 50 % (4/8) in BL/DLBCL], MUM1 [17 % (12/71) in BL, 63 % (5/8) in DLBCL, 63 % (5/8) in BL/DLBCL] and mean Ki-67 proliferation index [(93±4.4)% in BL, (83±14.3)% in DLBCL, (80±11.5)% in BL/DLBCL] were significantly different between BL and DLBCL and between BL and BL/DLBCL. The frequency of c-myc rearrangement [98 % (79/81) in BL,38 % (3/8) in DLBCL, 50 % (4/8) in BL/DLBCL] and an extra copy of bcl-6 [0 % in BL, 38 % (3/8) in DLBCL, 25 % (2/8) in BL/DLBCL] were also significantly different between BL and DLBCL and between BL and BL/DLBCL. Conclusion Diagnosis of the mature aggressive B cell lymphomas in pediatrics should be based on the comprehensive review and integration of morphologic, immunohistochemical and molecular genetic features. BL/DLBCL is more likely a subgroup of the DLBCL in pediatric population. The expression of CD10 and bcl-6 but not bcl-2, a high Ki-67 PI (＞90 %) and a c-myc rearrangement but not bcl-2 or bcl-6rearrangement are the features of BL. Regardless of the expression of CD10 and bcl-6, positive staining for bcl2, Ki-67 PI below 90 % and an extra copy of the bcl-6 favor a diagnosis of DLBCL or BL/DLBCL.

Objective To isolate and culture the rat limbal stem cells ( LSCs) in vitro,and investigate briefly their capacity for transdif-ferentiation into neural stem cells ( NSCs) with cytokine EGF,bFGF and RA.Methods LSCs derived from rats were cultured and identified by immunohistochemistry in vitro.LSCs were induced to differentiate into NSCs in the presence of EGF (20 ng/mL) ,bFGF (10 ng/mL) and with or without of RA(group 1 or group 2)(25 ng/mL) for seven days.Cultures without factors were used as control group.Then the neural marker Nestin of the coultured cells were measured by immunohistology staining.Furthermore,the positive cell rate was counted under micro-scope between the 2 groups and analyzed by statistical software.Results It showed that P63 was positive in LSCs.Nestin in both of the dif-ferentiation groups was positive at the rate of (77.01 ±6.32)%and (84.01 ±5.43)%respectively,of which the second group was higher than the first one (P<0.05).However,it was negative in the control group.A band of Nestin protein from cells was detected by western blot assay.Conclusion LSCs are successfully isolated and cultured in vitro.LSCs could be induced to differentiate into NSCs in the presence of EGF and bFGF.Moreover,the differentiation capability is enhanced in the condition of RA.

Objective To investigate the effect and safety of transcutaneous electrical stimulation at Zusanli acupoint for elimination of gastrointestinal poison in patients with oral organophosphorus pesticide poisoning. Methods A prospective study was conducted, including 62 patients with oral organophosphorus pesticide poisoning from September 2013 to February 2015 in the Department of Emergency of Xingtai People's Hospital of Hebei Province. The patients were divided into a observation group and a control group (each, 31 cases) in accord with the principle of simple random sampling. All the patients in two groups were given comprehensive treatment according to the diagnosis and treatment of the guide for organic phosphorus pesticide poisoning. In addition, the transcutaneous electrical stimulation at bilateral Zusanli acupoints was carried out in the observation group, once therapeutic time 30 minutes and every 8 hours once, and stopped until the discharge of melena. The incidence of vomiting after application of cathartics, the first stool time, the time of melena discharge, daily defecation frequency, the time of reaching atropinization, the total amount of atropine used, the time of cholinesterase (ChE) activity returning to its 1/2 normal activity, the length of stay in hospital, cure rate and mortality were observed in both groups. The changes in hemodynamics and pulse blood oxygen saturation (SpO2) were observed before and after transcutaneous electrical acupoint stimulation, and the occurrence of adverse reactions in the therapeutic course were observed in the observation group.Results After application of cathartics, the incidence of vomiting in control group was significantly higher than that in the observation group [32.2% (10/31) vs. 9.7% (3/31),P < 0.05]. In the observation group, the first stool time (hours: 9.3±3.6 vs. 11.6±5.2) and the time of melena discharge (hours: 11.3±5.3 vs. 14.5±6.8) were significantly shorter than those in the control group (both P < 0.05); while the frequency of bowel movements during catharsis was higher than that of the control group (times/d: 4.3±0.5 vs. 3.1±0.4,P < 0.01). In the observation group, the time reaching atropinization (hours: 66.3±22.8 vs. 84.6±24.2), the total amount of atropine used (mg: 66.3±22.8 vs. 84.6±24.2), and the time of ChE activity returning to its 1/2 normal range (days: 6.1±2.4 vs. 8.3±3.9) were significantly shorter than those in the control group (allP < 0.01). At the end of treatment, the average length of stay in hospital was shorter (days: 11.3±2.8 vs. 13.4±4.2,P < 0.05) and the cure rate was higher [96.8% (30/31) vs. 83.9% (26/31),P < 0.05] in the observation group than those in the control group; in observation group, the hemodynamics and SpO2 before and after acupoint electrical stimulation did not change significantly; in the course of treatment, no adverse reactions occurred.Conclusion The addition of transcutaneous electric stimulation at bilateral Zusanli acupoints in patients with oral organophosphorus pesticide poisoning has following advantages: lowering the incidence of vomiting during catharsis, enhancing the cathartic effect, promoting gastrointestinal poisoning discharge as soon as possible, reducing total atropine used during hospitalization, shortening the time reaching atropinization, shortening the duration of hospitalization, promoting the recovery of cholinesterase activity and elevating clinical therapeutic effects.
