Objective Percutaneous puncture of gasserian ganglion was guided by CT scan to improve the accuracy and reduce complications and to compare the efficacy of chemical mutilation with ethyl alcohol and adriamycin.Methods Ninety-two patients with primary trigeminal neuralgia (39 males, 53 females) aged 37-84 yrs were divided into two groups : A ethyl alcohol group ( n = 47) and B adriamycin group ( n = 45) . Secondary trigeminal neuralgia was excluded by preoperative CT scan. Percutaneous puncture of oval foramen was guided by CT and correct location of needle tip was confirmed by injection of contrast medium. 100% ethyl alcohol 0.5ml (group A) or 2% adriamycin 0.5ml was injected.Results The patients were followed up for 12 months after treatment. Neuralgia disappeared in 31 out of 47 patients in group A (alcohol group) and in 36 out of 45 patients in group B (adriomycin group) . Treatment failed in 13 patients in group A and 6 patients in group B, and was partly effective in the other patients. There were no severe side effects or complications. Conclusion Percutaneous puncture of gasserian ganglion guided by CT is effective and reduces complications. Adriamycin is more effective than ethyl alcohol for chemical mutilation.

Objective To study the effects of histone deacertylase inhibitor (TSA) on promoter methylation and expression of E-cadherin gene in a hepatocellular carcinoma cell line SMMC7721. Methods Hepatocellular carcinoma cell line SMMC-7721 was treated with TSA (300 nm/L), MTT method was used to investigate the growth inhibition ratio, TUNNL was conducted to measure the apoptosis ratio, methylation-specific PCR (MSP) was employed to detect changes in the CpG island methylation of E-cad promoter region, Western blot technique was used to detect the expression of E-cad gene and DNMT3b before and after TSA treatment, respectively. Results TSA decreases the SMMC-7721 cell viability and induces apoptosis, the growth inhibition ratio was 21.85% compared with control group. The apoptosis ratio of control group was (4.69±0.56)% ,the apoptosis ratio of TSA treatment group was (14.94±0.91)%. The apoptosis ratio of TSA treatment group was significantly higher than that of control group(P = 0.000). Before treated with TSA, the CpG island of E-cad promoter region was methylated, and the expression of E-cad was negative. TSA treatment induces demethylation of the CpG island in E-cad promoter region, causes the re-expression of E-cad. TSA reduces the expression of DNMT3b. Conclusions TSA decreases the SMMC-7721 cell viability and induces apoptosis, reverses the methylation status of E-cad promoter region, and resumes E-cad gene expression. TSA may induce demethylation through down-regulating the expression of DNMT3b.

Objective To explore the determination of urinary angiotensinogen (uAGT) in the urine of children with obstructive hydronephrosis and its relationship with impaired renal function, to provide a new and rapid reference index for the preoperative evaluation and postoperative follow-up of the children with hydronephrosis.Methods The data were collected from 48 children who were diagnosed as unilateral congenital renal pelvis and ureter obstruction in the outpatient or inpatient Department of Pediatric Surgery of the First Affiliated Hospital of Zhengzhou University,which were divided into operation group and non-operation group.There were 28 children in operation group(who were all severe hydronephrosis) ,who were all operated with dismembered pyeloplasty.There were 20 children in the non-operation group (who were all mild and moderate hydronephrosis).They temporarily had no surgery signs and hydronephrosis did not become increasingly serious for assuring the regular outpatient follow-up after being diagnosed as hydronephrosis;there were 20 children in the control group, 10 of which were male, and 10 female.The males were hospitalized children with hydrocele and the females were with inguinal hernia.Gender composition among the 3 groups, and the average age difference was not statistically significant.The clean urina of children in 3 groups was collected,3 times for operation group, once before operation and once in 6 weeks and once in 12 weeks after operation;3 times for non-operation group and control group with interval of 6 weeks in outpatient clinic.The children in operation group and non-operation group were all scanned for glomerular filtration rate (GFR) of diseased renal with radionuclide;enzyme-linked immunosorbent assay (ELISA) was adopted to determine the content of uAGT in the urine of the 3 groups of children, and automatic biochemical analyzer was used to measure the amount of urine creatinine (uCr).Results Before operation, in 6 weeks and 12 weeks after operation, uAGT / uCr average water of non-operation group and control group was significantly lower than the operation group, all the differences were statistically significant (F =34.360,14.683,5.035, all P ＜ 0.05).Preoperative and postoperative uAGT / uCr and GFR of diseased renal were of negative correlation(r =-0.647,-0.786, all P ＜ 0.05).In operation group, the preoperative and postoperative GFR average of diseased renal was 37.18 ± 7.31 and 45.27 ± 8.18.The difference of GFR changes was statistically significant before and after treatment (t =-3.971, P =0.000).Conclusions uAGT/uCr increased evidently in congenital renal pelvis and ureter obstruction patients who needed operation, so increase of uAGT might be the indicator of impaired renal function caused by obstructive hydronephrosis of children.

Objective To evaluate the effects on the mineral bone disorder using different calcium concentration citrate-based dialysate in maintenance hemodialysis (MHD) patients.To compare the concentrations of intact parathyroid hormone(PTH) with biointact PTH(1-84) in these patients.Methods Citrate dialysate with different calcium concentration (DCa 1.75,DCa 1.5,DCa 1.25 mmol/L)were used in turn in 15 stable MHD patients each week.Serum tCa and iCa were measured by automatic biochemistry analyzer.The concentrations of iPTH and bio-iPTH were compared.Results (1) The patients treated with DCa 1.75 citrate dialysate had increased serum iCa and tCa after dialysis,and PTH did not change significantly as compared to those findings before the dialysis.With the DCa 1.5 citrate dialysate,serum iCa and tCa were kept stable and PTH level was increased.With DCa 1.25 citrate dialysate,serum iCa and tCa decreased significantly and PTH decreased.(2)iPTH and bioPTH had excellent correlations.Variation of bio-iPTH was more correlated with the changes of calcium than iPTH.Conclusions Serum levels of iPTH,tCa and iCa can be kept stable in MHD patients treated with DCa 1.75 ～ 1.5 citrate dialysate.Bio-iPTH is a more sensitive marker for mineral bone disease than iPTH.

Objective To observe the curative effect of cervicogenic headache(CEH)treatment through the combination of pulse radio frequency(PRF)on the C2 dorsal rootganglion and continuous epidural space block.Methods Sixty patients with CEH in our hospital were randomly divided into groups A and B,30 cases in each group.The group A was treated with combination of PRF on cervical dorsal root ganglion and continuous epidural space block.The group B was treated with PRF on cervical dorsal root ganglion method.The pain VAS scores before treatment and at 1 week,3,6 months after treatment were compared between the two groups.Results Compared with pretreatment,the VSA scores at 1 week,3,6 wonths after treatment in the two groups had statistical difference(P＜0.05),moreover,the VAS score decrease in the group A was better than the group B.All the patients had no nerve and artery injury or infection complications.Conclusion It is safe and effective to treat cervical CEH through the combination of ganglion PRF on the cervical 2 dorsal root and continuous epidural space block.

Objective To evaluate the efficacy and safety of solifenacin in the treatment of bladder spasm after surgical operation of chlidren hypospadias.Methods From January 2014 to May 2015,60 cases of children more than 4 years old after surgical operation of hypospadias who had symptom of bladder spasm on the day of surgery were assigned into the study group (n =30) and control group (n =30),based on simple randomization.On the first day,the frequency of spasm,the duration of spasm and the incidence of urine extravasation were recorded regarded as the first day condition of bladder spasm.Patients in the study group were treated with solifenacin (5 mg once daily) for a nine days period from l th day postoperation.Patients in the control group were not treated with solifenacin.The frequency of spasm,the duration of spasm and the incidence of urine extravasation of the two groups were recorded and compared on the 3th and 9th day.Adverse events with solifenacin of two groups were recorded.The function of liver and kidney in the study group were recorded and compared.Results There were statistically significant differences(P ＜0.01) in favor of the study group over the control group in the aspect of the frequency of spasm,the duration of spasm and the incidence of urine extravasation on the 3th and 9th day.In the study group,the data compared among l th,3th and 9th was statistically significantly different,opposite to the control group.There was no statistically significant difference between the liver and kidney function of preoperation and the 9th day in the study group.The frequency of adverse events between two groups had no statistically significant difference.Conclusions Solifenacin is effective and safe in the treatment of bladder spasm after surgical operation of chlidren hypospadias

Objective To build a more perfect serum protein ifngerprint models for early diagnosis of ganglioneuroblas-toma (GNB) in children. Methods Thirty children with GNB and 30 normal control children were recruited. Serum samples were collected. Nonspeciifc serum protein was detected and studied by MB-WCX processing, SELDI-TOF-MS mass spectrom-etry system and MALDI-TOF/TOF platform. Results Through the SELDL-TOX-MS processing, a peak at 5920 m/z protein markers, and the expression of the markers was high in GNB children (6180.6±2328), compared with normal control children (419.1±493.3), the difference was statistically signiifcant (P<0.05);MALDI-TOF/TOF platform showed that the protein with a peak at 5920 m/z is identiifed as ApoC-Ⅲ. Conclusions m/z peak of 5920 protein is suggested as speciifc biomarker of GNB in children, can provide signiifcant reference for early diagnosis of ganglioneuroblastoma, and prognostic monitoring.
