OBJECTIVETo evaluate the efficacy and safety of Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion for pancreatic cancer with liver metastases (PCLM).

METHODSWe retrospectively selected 292 patients with PCLM who were treated by Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion at Tianjin Medical University Cancer Hospital from January 2001 to December 2010. All patients were assigned to the Western medicine treatment group (157 cases) and the integrative medicine treatment group (135 cases). Patients in the Western medicine treatment group were treated with gemcitabine (GEM)-based chemotherapy, and partial of them received regional arterial perfusion. Those in the integrative medicine treatment group additionally took Chinese herbs of clearing heat and eliminating mass for at least 4 weeks. The median survival time (MST) , adverse reactions and the incidence of complications were observed.

RESULTSThere was no statistical significance in general data between the two groups (P > 0.05). There was statistical difference in MST between the two groups (4.8 months vs 5.5 months, P < 0.05). No death occurred during chemotherapy or regional arterial perfusion. All toxic or adverse reactions were tolerable.

CONCLUSIONChinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion was effective and safe, and it could be optimally selected as palliative therapy for PCLM.

ObjectiveTo explore the association between angiotensin converting enzyme (ACE) gene insertion/deletion(I/D) polymorphism and cerebral infarction among Chinese people. MethodsThe ACE gene polymorphism was determined by PCR-RFLP in 242 patients with cerebral infarction and 283 controls. Multiple logistic regression was performed to explore the risk factors for cerebral infarction. ResultsAfter adjusting age, gender, alcohol drinking, smoking, education,history of diabetes mellitus and the primary hypertension, there was no significant association between ACE I/D polymorphism and cerebral infarction, either was hypertension and diabetes mellitus. The primary hypertension significanlly increased risk of cerebral infarction (OR=7.28,P =0.000). Both ACE ID/DD genotype and the primary hypertension showed a significant gene-environment interaction(r=1.62,OR=7.29), something as super multiplicative type 2 interaction. ConclusionAlthough ACE gene polymorphism is not risk factors of cerebral infarction, but ID/DD genotype had shown significant gene-environment interaction with primary hypertension in occurrence of cerebral infarcion.

Viral hepatitis was the most common infectious disease in china. But the diagnosis and treatment were varied because the viral hepatitis patients were hospitalized in different kinds of hospital such as infectious disease hospital, general hospital and Chinese medical hospital. It was necessary to know clinical characters and information of viral hepatitis patients in different hospitals. The general information, subtype distribution, prognosis, complication, medication and relations of onset with solar term from 41 180 viral hepatitis patients based on HIS data were analyzed. It was found that the age of patients between 18 to 59 years old was most; most patients were males. The national basic medical insurance was the most type of payment. The outcome of viral hepatitis in the youth and female were better than that in the old and male. Acute hepatitis was easer to restore than chronic hepatitis. Liver cirrhosis and hepatocellular carcinoma were the two most complications. The peak of onset was during summer solstice, slight heat and great heat. The most common Chinese medicine was Diammonium glycyrrhizinate and the most common western medicine was reduced glutathione. The combination of D. glycyrrhizinate with reduced glutathione, polyene phosphatidylcholine and thymosin was the main pattern. But It was not knew if the combination of western and Chinese medicine was the most effective therapy to protect liver function. It was necessary to take deeply research of the relationship between the combination therapy and their effectiveness.

OBJECTIVETo analyze the clinical features, diagnosis, treatment, and prognosis of epithelioid sarcoma (ES).

METHODSThe clinical data of 13 cases with epithelioid sarcoma in the Tianjin Medical University Cancer Institute and Hospital from March 1995 to December 2009 were collected and analyzed. There were 10 males and 3 females in the group, with an average age of 41.5 years (range: 13 to 68 years). Nine patients had classic ES and 4 had proximal-type ES. Surgery was the mainstay of treatment. After the operation, four patients received radiotherapy, five received chemotherapy, and one received chemoradiotherapy.

RESULTSOf the 13 cases, only 1 had multi-locus lesion. The average tumor size was (6.07 ± 1.34) cm. The lymph node involvement was found in 46.2% of the patients. Local and distant failure occurred in 50% and 30% patients, respectively. The most common site for dissemination was the lung. Four cases died within 3 years after initial operation. The 1-, 2-, 5-, 10-year overall survival rates of the 11 cases were 72.7%, 54.5%, 27.3% and 9.1%, respectively, with a median survival time of 27 months.

CONCLUSIONSEpithelioid sarcoma is a rare disease. The prognosis for patients with epithelioid sarcoma is poor because of a high propensity for local recurrence, lymph node metastases, and/or distant metastases. The definite diagnosis depends mainly on the pathologic examination. Wide surgical excision is the mainstay treatment, and radiation and chemotherapy have been used occasionally as adjuvant therapy but have had limited success.

Naringenin (1) was transformed to three metabolites (2-4) by Mucor sp. Based on LCMS(n)-IT-TOF and NMR spectroscopic data, 2-4 were identified as naringenin-7-O-sulphate, naringenin-4'-O-sulphate, and naringenin-5-O-sulphate, respectively. These results might provide hints to the mammalian/human metabolism of naringenin.

To obtain the recombinant pZP3alpha protein for the study of the contraceptive vaccines, the DNA sequence (446-1423) encoding purified pZP3alpha was inserted into a vector--pPICZalphaA. The recombinant plasmid pPICZalphaA-pZP3alpha was linearized and then transformed into Pichia pastoris GS115 by electroporation. Engineering strains were attained by screening with zeocin and induced to produce rpZP3alpha in high-density fermentation. Then rpZP3alpha was purified by Cu2+ metal affinity column chromatography from the separated and concentrated fermentative supernatants. The purified rpZP3alpha was identified by SDS-PAGE and Western blot, and the quantity, purity and rate of recovery of the rpZP3alpha were analyzed by Quantity One software. One male rabbit was immunized with the Cu-NTA-purified rpZP3alpha. The antibody responses against rpZP3alpha and porcine ZP were detected by ELISA and the indirect immunofluorescence. Engineering strains expressing rpZP3alpha in secretion were constructed. A 46kD component named rpZP3alpha which can react with anti-pZP3 antibody was purified from fermentative supernatants of engineering strains and the average yield of purified rpZP3alpha obtained from fermentative supernatants was 8mg/L. The purity and the rate of recovery were up to 92% and 63% respectively. The anti-rpZP3alpha antiserum was prepared by immunization of a male rabbit with purified rpZP3alpha. This anti-rpZP3alpha antiserum could react with rpZP3alpha and purified pZP3 in ELISA and bind to porcine zona pellucida which produced bright green fluorescence in the indirect immunofluorescence. The rpZP3alpha (46kD) protein could be successfully expressed in the Pichia pastoris expression system. And this protein retained the immunogenic activity of natural pZP3.
