OBJECTIVETo explore the relationship between Pi-Wei Damp-Heat Syndrome (PWDHS) with expression of aquaporin (AQP) 3,4 gene in gastric mucosa and the effects of Qingre Huashi Recipe (QHR) on the expression.

METHODSSixty-eight patients with chronic superficial gastritis were differentiated into Pi-Wei Damp-Heat Syndrome group (PWDHS, n = 53, 19 cases with predominant Dampness, 14 cases with predominant Heat, 20 cases with Dampness equal to Heat) and Pi deficiency Syndrome group (PDS, n = 15). The PWDHS were treated with QHR. The expression of AQP 3,4 gene in the two groups were determined by fluorescence quantitative polymerase chain reaction (FQ-PCR).

RESULTSExpression of AQP 3 gene in PWDHS was higher than that in PDS and the healthy group, but the difference showed no statistical significance. Expression of AQP 4 gene in PWDHS was obvious higher than that in PDS and the healthy group (P <0.05 or P <0.01), but the difference of AQP 4 gene expression between PDS and the healthy group was insignificant. Comparison among various sub-types of PWDHS showed that the AQP 4 gene expression in the predominant dampness > dampness equal to heat> predominant heat. AQP 3,4 gene expression in PWDHS was significantly decreased after QHR treatment, especially in the cases with predominant dampness syndrome (P <0.01), approaching that in the healthy group and PDS.

CONCLUSIONAbnormal expression of AQP 3,4 gene may be one of the possible mechanisms of PWDHS pathogenesis, Chinese herbs could influence AQP 3,4 gene expression to play a key role in treatment.

Objective To discuss how to protect the intracranial vertebral artery and posterior inferior cerebellar artery by observing and measuring the intracranial vertebral artery in the surgery adopt far lateral approach. Methods Mimicking far lateral approach, 20 adult cadaveric heads connected to neck fixed with 10% formalin were dissected. Intracranial segment of the vertebral arteries and their main branches were exposed and measured under operating microscope. Results The intracranial vertebral artery joined with the contralateral one into the basilar artery after traveling through the atlanto-occipital sulcus. The relationship between the vertebral artery and the hypoglossal nerve is close. Thirty sides (75%) of the vertebral arteries traveled to pons medulla sulcus in front of the hypoglossal nerve roots and 2 sides (5%) behind the hypoglossal nerve roots, while 8 sides (20%) traveled among the hypoglossal nerve roots; 70% of the vertebral arteries were contacted to the hypoglossal nerve roots, 30% of which compressed the hypoglossal nerve. The main branches of intracranial segment of the vertebral arteries were the posterior inferior cerebellar arteries, the anterior spinal arteries, the posterior meningeal arteries,and some perforating arteries. Posterior inferior cerebellar arteries all originated from the intracranial vertebral artery were the largest vertebral artery's branches; their trip was mostly loop-shaped and they had close relationship with Ⅸ, Ⅹ, Ⅺ cranial nerves. The starting points of the posterior inferior cerebellar arteries were different, even in the same specimen, but most of them originated from the upper 1/3intracranial vertebral artery. No anterior inferior cerebellar artery was noted originated from the vertebral artery in our specimen. Anterior spinal arteries originated from the vertebral arteries joined with the branches of the bilateral vertebral arteries and traveled down through the tortuous anterior median fissure to supply the spinal cord. Conclusion Being familiar with the characteristics and anatomic vertebral arteries variations of the intracranial vertebral artery and its branches can contribute to identify and protect the intracranial segment of the vertebral artery and its main branches in the surgery adopt far-lateral approach.

The galacto-oligosaccharide was synthesized continuously by immobilized Bacillus stearothermophilu producing β-galactosidase in fibrous bed reactor. The effect of substrate concentration, pH, reaction temperature and retention time on production of GOS was investigated. The optimal reaction conditions were determined. Substrate concentration were 450 g/L;Reaction temperature was 55℃; pH was 7.0; Residience time was 100 min. The product yield reached up to 50.7 %. GOS synthesis was promoted by feeding 1.5 % D-glactose after 24h. The immobilized cell reactor can work stably for 120h.

Objective： The current study was designed to investigate the role of foods such as fish juice, pickles, bacon, salted fish, smoked food, fruit and vegetables in the etiology of esophageal cancer in Chaoshan region of China. Method： A large case-control study was conducted to investigate 1248 patients with squamous cell carcinoma of the esophagus and 1248 controls matched by sex and age. Results： After adjusting for the effects of occupation, areas of residence, income, alcohol, cigarette and tea, a strong association with a clear dose-response was observed between the frequencies of fish juice eating and esophageal cancer (P<0.01), and the relative risk for women was 23.5 and for men was 3.1, respectively. The results for pickles were similar to fish juice. A protective effect of fruits on esophageal cancer was observed both in women (OR=0.13) and in men (OR=0.46), and the risk was decreased (P< 0.01) as frequencies of fruits eating was increased. The risks were significantly higher in bacon and salted fish consumers than that in non-consumer, but the dose-response relationship was not significant. No significant effects, however, were detected in vegetables and smoked food consumption. Conclusions:To the authors' knowledge, this is the first report on relationship between the fish juice and high risk of esophageal cancer in population. Further epidemiological and experiment study are required to find a biological causal relationship between them.

OBJECTIVETo investigate the clinical features of Candida albicans sepsis in preterm infants.

METHODSRetrospective analysis was performed on the clinical data of 13 preterm infants with Candida albicans sepsis, who were born at 28 to 36 weeks of gestational age and who weighed between 1400 and 2815 g.

RESULTSThe infants were infected with Candida albicans at the age of 19±11 d, with the main clinical manifestations being apnea, poor response, poor skin perfusion, blood oxygen concentration decrease, dark skin, yellowish skin, heart rate increase in the rest state, copious phlegm and difficulty in weaning from the ventilator. The infants showed significantly decreased platelet and increased C-reactive protein (CRP), platelet distribution width (PDW), alanine transaminase (ALT), creatine kinase isoenzyme-MB (CK-MB), total bilirubin (TBIL), creatine kinase (CK), and lactate dehydrogenase (LDH). CK and LDH were significantly decreased after 2 weeks of antifungal therapy. Only 3 cases developed drug resistance to fluconazole and these showed response when treated with voriconazole instead. Of the 13 cases, 10 were cured, 2 abandoned therapy and 1 died.

CONCLUSIONSThe clinical manifestations of Candida albicans sepsis are nonspecific in preterm infants. Infectious diseases are probably caused by Candida albicans in preterm infants 2-3 weeks after birth. Preterm infants show decreased platelet and increased CRP, PDW, ALT, CK-MB, TBIL, CK, and LDH when infected with Candida albicans.

OBJECTIVETo investigate the effect of curcumin (Cur) on radiosensitivity of nasopharyngeal carcinoma cell CNE-2 and its mechanism.

METHODThe effect of curcumin on radiosensitivity was determined by the clone formation assay. The cell survival curve was fitted by Graph prism 6. 0. The changes in cell cycle were analyzed by flow cytometry (FCM). The differential expression of long non-coding RNA was detected by gene chip technology. Part of differentially expressed genes was verified by Real-time PCR.

RESULTAfter 10 micro mol L-1 Cur had worked for 24 h, its sensitization enhancement ratio was 1. 03, indicating that low concentration of curcumin could increase the radiosensitivity of nasopharyngeal carcinoma cells; FCM displayed a significant increase of G2 phase cells and significant decrease of S phase cells in the Cur combined radiation group. In the Cur group, the GUCY2GP, H2BFXP, LINC00623 IncRNA were significantly up-regulated and ZRANB2-AS2 LOC100506835, FLJ36000 IncRNA were significantly down-regulated.

CONCLUSIONCur has radiosensitizing effect on human nasopharyngeal carcinoma CNE-2 cells. Its mechanism may be related to the changes in the cell cycle distribution and the expression of long non-coding IncRNA.
