Objective To evaluate whether P53 gene mutation was related with the pathogenesis of ovarian malignant epithelial tumors or not.Methods P53 gene mutation in exons 5-8 was detected by polymerase chain reaction product-single strand conformation polymorphism analysis (PCR-SSCP).Results The mutation in benign tumors: 3(10%) cases, but in malignant epithelial tumor:19(38%) cases(P0 05).Conclusions P53 gene mutation in exons 5-8 was probably related with the pathogenesis of ovarian malignant epithelial tumors, but was not related with histological grade.

Objective To investigate the clinical efficacy of electroacupuncture at Huatuo jiaji points plus acupuncture point injection in treating postherpetic neuralgia.Methods Sixty-two patients with postherpetic neuralgia were randomly allocated to a treatment group of 32 cases and a control group of 30 cases. The treatment group received electroacupuncture at Huatuo jiaji points plus acupuncture point injection and the control group, oral administration of carbamazepine tablets, vitamin B1 and vitamin B12. The pre-treatment and post-treatment clinical symptom score and VAS score were recorded in the two groups and the clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 93.8% in the treatment group and 66.7% in the control group; there was a statistically significant difference between the two groups (P<0.01). There were statistically significant pre-/post-treatment differences in clinical symptom item scores (pain, pruritus, burning sensation and sleep) in the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the VAS score in the two groups (P<0.05). There was a statistically significant difference in pre-/post-treatment VAS score difference value between the treatment and control groups (P<0.05).Conclusion Electroacupuncture at Huatuo jiaji points plus acupuncture point injection is an effective way to treat postherpetic neuralgia.

Ion chromatography(IC)can make up the deficiency of LC or GC for the analysis of ionic drugs because of the unique separation mechanism,so IC is more and more widely applied in the field of drug analysis. In the paper,the application of IC is reviewed in the quality control of chemical drugs.

Objective To study the influence of HBV infection for gastromucous membrane in chronic hepatitis B and cirrhosis and its pathogenesis.Methods The liver biopsy,gastroscope,liver function and HBVM were detected at the same time in 60 patients with chronic hepatitis B and cirrhosis.HBsAg and HBcAg in the tissues of liver and gastromucous membrane were detected by SP immunohistochemistry.Results The damage of gastromucous membrane were found in 56 of 60 patients.Its damage degree was showed as moderate and severe.The other 34 showed mild and moderate damage(P

Objective To investigate the imaging diagnostic value of ureter cysts.Methods The intravenous pyelogram(IVP), CT MRI and ultrasonic data of 17 cases of ureter cyst were analysed trtrospectively. Results All patients were correctly diagnosed preoperatively. The application of US and intravenous cystography may aid to improvement of diagnosis.Conclusion The combination of multiimaging modalities was proved to be of great value in diagnosis of ureter cysts.

Objective To discuss the expression and mutation of β-catenin gene in breast carcinoma.Methods 119 breast carcinomas, 72 adenosis of breast tissues and 40 normal breast tissues were studied.Using immunohistochemistry studies to detect the expressions of β-catenin, then analyzing their relationship with the clinicopathological features of breast carcinomas. Gene mutation of β-catenin (exon 3) in 44 cases of breast carcinoma were analyzed by polymerase chain reaction (PCR) and then by direct sequencing.ResultsIn 40 cases of normal breast tissues, epithelial cells showed equally strong membranous of β-catenin protein at the cell-cell boundaries. The abnormal rate of β-catenin in breast carcinomas (78.15 %) was much higher than that of adenosis of breast tissues (44.44 %), the significant correlation was found (P＜0.01). The abnormal expression of β-catenin was associated with lymph node metastasis (P=0.031). Mutation of β-catenin gene was not detected in 44 cases of breast carcinoma, while the abnormal rate of β-catenin in 44 cases of breast carcinoma was 77.30 %. Conclusionβ-catenin abnormal expression could be considered as an useful marker for determining metastasis and prognosis of human breast carcinoma and for guiding treatment. β-catenin abnormal expression is not caused by β-catenin gene mutation, maybe by other mechanisms. It needs further study.

ObjectiveTo report clinical, pathological and molecular genetic features in a Chinese family with hereditary motor and sensory neuropathy type 6. MethodsThe index case is a 15 years old boy.He developed progressive distal limb weakness at the age of 5.The disease deteriorated slowly,accompanied with contracture of achilles' tendon. At the age of 11 years old he suffered from decrease of visual acuity. At the age of 12, he found the muscular atrophy of both hands without sensory disturbances.Visual evoked potential revealed prolonged latency of bilateral P100. Ophthalmological examination showed bilateral optic atrophy. His mother had the similar symptoms at the age of 7 and reduced visual acuity at the age of 10. Nerve conduction velocity revealed in both pat1ents no compound motor and sensory nerve action potentials in most nerves or slightly reduced nerve conduction velocities with severely reduced amplitudes of the compound motor and sensory nerve action potentials. Sural nerve biopsy was performed on the proband.The sequence of MFN2 gene was analyzed in DNA from the index, his mother and 100 healthy controls.ResultsSural nerve biopsy revealed severe loss of myelinated fibers with few regenerating clusters.Ultrapathological examination showed a few of atypical bulbs of myelinated fibers, occasionally regenerating clusters, mitochondrial swelling and aggregation in a few of axons. A new mutation of W740R mutation in MFN2 gene has been identified in the index case, her mother, but not in 50 healthy controls. Conclusions A novel MFN2 gene mutation result in hereditary motor and sensory neuropathy type 6.Mild visual loss appeares after the lesion of spinal nerves. Demyelination of peripheral nerve appears in the disease.

Objective To determine the location and degree of fallopian tube obstruction,providing a safe reliable and effective treatment. Method 50 infertile women with unilateral or bilateral fallopian tube stenosis, adhesion and obstruction were selected for this study, with ages range of 23 to 38 years. Selective salpingography was performed using co-axiol catheterization with micro-guide wire mechanism combined with recanalization, anti-inflammatory agents during the procedure and postoperative period. Results The rate of properly performed catheter and recanalization reached 92% and 68.7%, respectively. During the follow-up of one year, 23 cases (23/50, 46%) obtained ability of pregnancy. Conclusion Selective salpingography with fallopian tube recanalization is a minimally invasive method to treat tubal infertility. (J Intervent Radiol, 2006, 15: 290-292)
