Objective To study the expression and function relations of the p63 in ovarian serous carcinoma,and compare them with normal ovary tissue.Methods RT-PCR,in situ hybridization and im- munohistochemistry were used to detect the expression of the p63 in ovarian serous carcinoma,ovarian bor- derline serous tumors,ovarian benign serous tumors and normal ovary tissues.Results All samples ex- pressed p63 mRNA through RT-PCR and immunohistochemistry,while the levels of expression in ovarian tu- mors was higher than that of normal ovary.p63 in human borderline and malignant ovarian tumors was higher than that in human benign ovarian tumors with significant difference,which suggested p63 may play great roles in the origin and progression of ovarian tumors.The result of in situ hybridization showed that positive expression rate of p63 mRNA in ovarian cancer (92.1%) was significantly higher than that in normal ovary(0) or LWP ovarian cancer(50.0%).Conclusion Expression of p63 plays an important role in the development of varian carcinoma,and along with the difference of histological stage and clinico-pathological stage,the ex- pression of p63 gene and protein level were different.

Objective: To observe the effect of acupoint massage plus Vitalstim electrical stimulation on deglutition function and surface electromyography (SEMG) of deglutition muscle groups. Methods: A total of 60 patients with deglutition disorder after stroke were selected and divided into an electrical stimulation group, a massage group and an integrated group according to the random number table method, with 20 cases in each group. Patients in these three groups were given the same routine rehabilitation training for deglutition. In addition, patients in the electrical stimulation group were given extra Vitalstim electrical stimulation, patients in the massage group were given extra acupoint massage on the head, face and neck, and patients in the integrated group were given extra acupoint massage plus Vitalstim electrical stimulation. Fujishima Ichiro food intake level scale (FILS) was scored before and after treatment. The swallowing duration and maximal amplitude of masseter muscle in SEMG were evaluated before and after treatment. Results: After treatment, the FILS score and the maximal amplitude of recruitment potential generated by muscular contraction of masseter muscle group in the three groups were higher than those before treatment (all P<0.05), and the swallowing duration of masseter muscle group was shortened compared with that in the same group before treatment (all P<0.05). After treatment, the FILS score in the integrated group was higher than that in the electrical stimulation group and the massage group (both P<0.05). The swallowing duration of masseter muscle group measured by SEMG was lower than that in the electrical stimulation group and the massage group (both P<0.05), while the maximal amplitude was higher than that of the electrical stimulation group and the massage group (P<0.05). After treatment, there were no significant differences in the FILS score, swallowing duration and maximal amplitude of masseter muscle group between the electrical stimulation group and the massage group (all P>0.05). Conclusion: Both acupoint massage and electrical stimulation can improve the deglutition function in patients with deglutition disorder after stroke, and improve the coordination and flexibility of masseter muscle. The integration of the two is more effective.

OBJECTIVETo analyze the efficiency of cervical lymph node metastasis dissection and postoperative morbidity after selective three-field lymph node dissection (3FLND) for thoracic esophageal squamous cell carcinoma, and explore the proper selection conditions.

METHODSAccording to the conditions as follows: systemic evaluation, tumor T staging, tumor location, cervical CT and ultrasonography and the number of lymph nodes metastases, 85 patients with thoracic esophageal squamous cell carcinoma were selected and received 3FLND.

RESULTSIn the same period 45.5% (85/187) of the patients received 3FLND selectively based on the conditions. The rate of the cervical lymph nodes metastasis was 40.0% (34/85). The rate of the cervical positive lymph nodes of the upper, middle and lower thoracic esophageal carcinomas with enlarged lymph nodes suggested by cervical CT and ultrasonography was 68.4% (13/19), 41.7% (20/48) and 16.7% (1/6), respectively. Twelve patients with upper thoracic esophageal carcinoma with enlarged lymph nodes unrevealed by cervical CT and ultrasonography showed no histopathological lymph node metastasis. In the same period 17.1% (32/187) of the patients were selectively not undergone three-field lymph node dissection. The cervical lymph node metastasis rates in patients with upper and middle mediastinal lymph node metastasis were 79.3% (23/29) and 58.6% (17/29), significantly higher than 8.9% (5/56) and 7.1% (4/56) in the patients without upper and middle mediastinal lymph node metastasis (P<0.05). There was no in-hospital mortality in the group. The incidence of pulmonary complications and over-all postoperative morbidity was 24.7% and 42.4%, respectively.

CONCLUSIONSSelective 3FLND based on certain conditions can reduce the risk of postoperative morbidity and improve the efficiency of metastatic cervical lymph node dissection in thoracic esophageal squamous cell carcinoma. The thoracic tracheoesophageal groove positve lymph node indicated by CT scans should be one of selective conditions for 3FLND. The upper thoracic esophageal carcinoma should selectively receive 3FLND. The selection standards should be more strict for the lower thoracic esophageal carcinoma.

OBJECTIVETo study the effect of red peony root (RPR) on serum proteome in rat suffering from noxious heat with blood stasis Syndrome (NH-BS).

METHODSThe differences of serum proteome among rats in four groups, treated with lipopolysaccharide (LPS), RPR, LPS + RPR and saline respectively, were analyzed by bi-dimensional electrophoresis (2DE) assay. LPS was administered by intravenous injection and RPR by oral intake.

RESULTS(1) Serum of rats with LPS induced NH-BS showed significant changes in volume of serum protein (xPr) in 13 points on 2DE collagen, the volume of xPr 16 and 19 were significantly lower, volume of xPr 1, 2, 3, 4, 6, 7, 8, 9, 11, 12 and 23 were significantly higher respectively, as compared with those in the normal control group. (2) After being treated with RPR, the increased volume of xPr 1, 2, 3, 4 and 9 significantly decreased, and the decreased xPr 16 significantly increased, with xPr 2, 3 restored to normal level but the xPr16 still lower and xPr 1, 4, 9 higher than those in the normal group. RPR showed interaction with LPS on xPr 1, 3, 9, and 16. (3) For xPr 19, the interaction of RPR with LPS might be synergistic. (4) In the group treated with RPR, volumes of xPr 13 and 14 were significantly higher and those of 15, 17 were significantly lower than those in the normal group respectively, but the similar changes didn't found in the LPS group.

CONCLUSIONThe molecular basis of therapeutic effect of RPR on NH-BS might be through the regulation of xPr 1, 2, 3, 4, 9 and 16.

We revisited the "Xiao Chaihu Decoction event (XCHDE)" occurred in late 1980s in Japan and the Bupleuri Radix related adverse drug reaction (ADR) reports in China After careful review, comparison, analysis and evaluation, we think the interstitial pneumonitis, drug induced Liver injury (DILI) and other severe adverse drug envents (ADEs) including death happened in Japan is probably results from multiple factors, including combinatory use of XCHDE with interferon, Kampo usage under modern medicine theory guidance, and use of XCHD on the basis of disease diagnosis instead of traditional Chinese syndrome complex differentiation. There are less ADE case reports related to XCHD preparation in China compared to Japan, mostly manifest with hypersensitivity responses of skin and perfuse perspiration. The symptoms of Radix Bupleuri injection related ADEs mainly manifest hypersensitivity-like response, 2 cases of intravenous infusion instead of intramuscular injection developed hypokalemia and renal failure. One case died from severe hypersensitivity shock. In Chinese literatures, there is no report of the interstitial pneumonitis and DILI associated with XCHDG in Japan. So far, there is no voluntary monitoring data and large sample clinical research data available. The author elaborated the classification of "reevaluation" and clarified "re-evaluation upon events" included the reaction to the suspected safety and efficacy events. Based on the current status of the clinical research on the Radix Bupleuri preparations, the author points out that post-marketing "re-evaluation upon suspected event" is not only a necessity of continuous evaluation of the safety, efficacy of drugs, it is also a necessity for providing objective clinical research data to share with the international and domestic drug administrations in the risk-benefit evaluation. It is also the unavoidable pathway to culture and push the excellent species and famous brands of TCM to the international market, in that it enhances the pharmaceutical manufactures the ability to control enterprise risk and eliminate the negative impact on traditional Chinese medicine. With the widely used and ADR report concentrated Radix Bupleuri injection as an example, the author provide a new approach to post-marketing clinical research.

Objective To compare the different effects of 1% diatrizoate meglumine,2.5% mannitol and water as oral contrasts in PET/CT scan in gastrointestinal tract delineation and 18F-fluorodeoxyglucose (FDG) uptake. Methods Sixty-one patients referred for PET/CT scan without gastrointestinal diseases were divided into three groups randomly ( random number method). One liter of 1% diatrizoate meglumine,2.5% mannitol,or water was orally taken by groups 1 (25 cases),2 (20 cases) and 3 ( 16 cases),respectively before scan. The scan was performed with GE Discovery LS PET/CT scanner in two-dimensional (2D) mode 50 min after 18F-FDG (5.55 MBq/kg) injection. Patients with abdominal lesions were excluded from this study. The degree of gastrointestinal filling and 18F-FDG uptake was evaluated by 3 nuclear medicine physicians using visual analysis according to a 4-grade classification method:none,mild,moderate,and high. Statistically analysis was performed by Kruskal-Wallis,Mann-Whitney and paired t tests.Results Both the differences of serum glucose and insulin levels were not significant before and after contrast taken in group 2. Group 2 had better gastrointestinal filling than that of group 1 and also better than group 3 except in rectum. The stomach,jejunum,ascending,and transverse colon were better filled in group 1 than in group 3. The degree of 18F-FDG uptake of group 3 was significantly higher than that of group 2 in stomach,jejunum and ileum (z= -3. 192,-3.290,-3.290,all P＜0.05),and was also significantly higher than that of group 1 (z = - 3. 603,P ＜ 0.05) in jejunum. The degree of 18 F-FDG uptake of group 3 was significantly lower than that of group 1 in ascending colon (z = - 2. 706,P ＜ 0. 05 ) and was significantly lower than that of group 1 and 2 in transverse and descending colon (z= - 3. 503,- 2.403,- 4.225,-4. 027,all P ＜0.05),and was also significantly lower than that of group 2 in rectum (z = -4. 128,P ＜0. 01 ). The maximum CT values in stomach,jejunum,ileum and ascending colon in group 1 were ( 132 ±23),(191 ±31),(313 ±47) and (374±53) HU,respectively,whose difference was significant (t = -7.088--1.781,all P ＜0. 01 ). Conclusion Oral iso-osmotic mannitol intake has better gastrointestinal filling and less physiological 18F-FDG uptake compared to diatrizoate meglumine and water.

Objective To evaluate the possible mechanism of traumatic brain injury (TB1) affecting the speed of bone fracture healing.Method TBI combined with unilateral tibial fracture (group A) was used to build multiple injury model and simple unilateral tibial fracture (group B),and the FOS,JUN,bFGF,and VEGF protein expression in different time points between the two groups were compared,and roentgenogram was used for the evaluation of bone healing.Results The expression of FOS,JUN,bFGF,and VEGF protein of the cerebral tissue was low in the normal rats,but was slightly enhanced in group B.There was consistence of development for FOS and JUN expression in the brain tissue in group A,reaching peak at post-TBI 3 hours,and then reducing to control level after 12 hours.The bFGF and VEGF reached peak at post-TBI 12 hours and 24 hours and reduced to control level after 72 hours,respectively.In group A and group B,an increase in the FOS,JUN protein expression around the fracture site was observed at 3 hours after injury,which reached the peak at 6 hours,and reduced to the control level after 24 hours;the comparison between group A,group B and the control group at 3 hours,6 hours and 12 hours had significant difference (P
