Objective To investigate the relation of morbidity law of upper gastronintestinal hemo rrhage and cycle of Heavenly Stems and Earthly Branches in Gansu province. Methods Investigative statistical forms were set up and analyzed by computer about twelve years in-patient of upper gastronintestinal hemorrhage in TCM hospital of these district. Results High morbidity corresponded with theory of YUNQI, in 1988 (year of the fifth of ten Hevenly Stems and the fifth of the twelve Earthly Branches, HUOYUN is high sufficient), 1995 (year of the second of ten Hevenly Stems and the last of the twelve Earthly Branches, JINYUN is insufficient), and Baiyin district in 1994 (year of the first of ten Hevenly Stems and the eleventh of the twelve Earthly Branches TUYUN is high sufficient), Cheng district in 1996 (year of the third of ten Hevenly Stems and the first of the twelve Earthly Branches, SHUIYUN is high sufficient), YUNQI was high sufficient or insufficient, which causing diseases conform to five internal organs and geographical position. Conclusion Morbidity law of upper gastronintestinal hemorrhage corresponds with cycle of Heavenly Stems and Earthly Branches.

Objective To investigate the relation between TCM syndromes of upper gastrointestinal hemorrhage and solar terms change in different years. Methods Data of upper gastrointestinal hemorrhage in-patients in seven districts of TCM hospital of Gansu province in twelve years were filled in investigative statistical forms and analyzed by computer. Results There was obvious difference in TCM syndromes among different solar terms and different years. Conclusion Atmospheric pressure, atmospheric temperature, air humidity, diurnal temperature range of solar terms change in different years directly effect TCM syndromes of upper gastrointestinal hemorrhage.

Objective We discussed the nursing of patients with superior mesenteric artery syndrome (SMAS) through duodenal circular drainage operation. Methods We carried out a retrospective analysis for 42 SMAS patients undergoing duodenal circular drainage operation from. 1959 to 2007. They were given preoperative psychological nursing, correct lying style, postoperative nutritional support and health education instruction. The treatment effect was observed. Results All patients cured and left hospital. The treatment effect was good after one to fifteen years of follow-up visit. Five patients who changed to adopt duodenal circular drainage operation also got good result after nine to ten years of follow-up visit. The incidence of anastomotic ulcer and anastomotic stenosis as well as reflux gastritis was not seen. Conclusion SMAS could be cured earlier through duodenal circular drainage operation and effective nursing.

The diagnostic value of keratin-18 and its fragments in liver diseases has drawn increasingly interests in recent years,but studies on its application in chronic hepatitis B is still few.This paper reviews the circulating levels of keratin-18 fragments M30 and M65 in chronic hepatitis B and its application in the future.

Objective To compare the result differences of different dynamic nerves transferring to different segments of the radial nerve. Methods From 1997 to 2000, different ways of intercostal nerves or contralataral C 7 transfering to different segments of the radial nerves were carried out in 36 cases with total avulsed brachial plexus injuries that were followed up for average 42.39 months. Four-fold table was selected to statistically calculate the effective rate of muscle strength recovery. Results The total effective rate was 56% (20/36). The effective rate of the functional rehabilitation of elbow extension was 5/8 in the group with neurotization to radial nerve trunk and 4/4 in the group with neurotization to branches innervating the triceps brachii muscle of radial nerve. The highest effective rate up to 75% (9/12) of the functional rehabilitation of wrist and digit extension belonged to the group with contralateral C 7 transferring to the radial nerve segment in the humeral spiral groove where branches innervating the triceps brachii muscle had already diverged. Conclusions The way of neurotization to radial nerve trunk and to branches innervating the triceps brachii muscle of the radial nerve can win good functional rehabilitation of elbow extension. Contralataral C 7 transfering to the radial nerve segment in the humeral spiral groove ranks the best way for function recovery of the wrist extension. Age below 30 years and operation interval less than 12 months are helpful for functional rehabilitation of the radial nerve.

Objective To investigate the inhibitory effects of docosahexaenoic acid (DHA)and 5-fluorouracil (5-FU)in combination on human gastric cancer cell line AGS in vitro .Methods Human gastric cancer line AGS was treated with different concentrations of DHA and 5-FU alone or in combination.The inhibition of cell proliferation was evaluated by MTT assay.Dose of median (IC50 )of drugs (alone or in combination)and the combination index (CI)were calculated using the median-effect equation and the combination index equation of Chou-Talalay.Flow cytometry was used to detect the cell cycle distribution.The expression of mitochondrial respiratory membrane protein complex in AGS cells was analyzed with Western blot.Results DHA and 5-FU alone or in combination could markedly suppress the proliferation of AGS in significantly time-dependent and dose-dependent manners (P <0.05).IC50 values with DHA or 5-FU administered for 24 h and 48 h were 5 1.60 μg/mL (DHA:24 h),34.82 μg/mL (DHA:48 h),45.90 μg/mL (5-FU:24 h),and 1 6.86 μg/mL (5-FU:48 h), respectively.DHA remarkably strengthened the inhibitory effect of 5-FU and decreased IC50 of 5-FU by 3.56 -2.1 5 folds.The combination of DHA and 5-FU showed synergism.Flow cytometry showed that AGS cells treated with DHA and 5-FU were arrested in G0/G1 phase and the proportion of AGS cells in G0/G1 phase increased compared with that in the control group,DHA group and 5-FU group,while the proportion of the cells in S phase decreased significantly (P < 0.05 ).Western blot showed after treatment with DHA and 5-FU for 48 h,the expression of mitochondrial respiratory membrane protein complex was significantly decreased compared with control group,DHA group and 5-FU group (P <0.05).Conclusion DHA could act synergistically with 5-FU in inhibiting the growth of gastric carcinoma cells,and meanwhile decrease the dose of 5-FU.The mechanism may be associated with cell cycle arrest in G0/G1 phase and interference in the energy metabolism of AGS cells due to inhibition of the expression of mitochondrial oxidative respiratory chain complexes by the two compounds.

Objective To evaluate value of narrow band imaging(NBI) endoscopy for children with abdominal Henoch?Schonlein purpura ( HSP ) . Methods A total of 46 patients with abdominal HSP were enrolled into the observation group(NBI intervention) from November 2010 to February 2016.Diagnostic rates of white light and NBI endoscopy in abdominal HSP patients, IgA positive rates of targeted biopsies and severe complications were retrospectively analyzed. A total of 25 abdominal HSP patients with no NBI intervention admitted from 2007 to 2009 were randomly enrolled into control group. Data of the control group were compared with those of observation group. Results In observation group, the diagnostic rate under NBI was significantly higher than that under white?light endoscopy[91. 3%(42/46)VS 67. 4%(31/46),χ2=8. 02,P<0. 05]. IgA positive rates of targeted biopsies under NBI was significantly higher than that under white?light endoscopy [ 95. 7%( 88/92 ) VS 69. 6%( 64/92 ) ,χ2 = 21. 79, P<0. 05 ] . Three patients developed such serious complications as digestive hemorrhage as predicted. Compared with control group, abdominal pain and blood stool relief time (10. 96±5. 32 d VS 19. 68±4. 29 d,t=7. 50,P<0. 01), fasting time(10. 37±5. 42 d VS 8. 80± 3. 71 d,t=7. 73,P<0. 01), hospital stay (18. 80±7. 11 d VS 23. 12±4. 36 d, t=3. 16,P<0. 01), time of stool occult blood negative ( 11. 41 ± 6. 30 d VS 19. 12 ± 4. 09 d, t=6. 22, P<0. 01 ) in observation group were significantly shortened. Conclusion NBI endoscopy is valuable for improving the diagnostic accuracy and biopsy accuracy and complication prediction of abdominal Henoch?Schonlein purpura in children.

Objective:To compare the therapeutic and adverse effects of chemotherapeutic regimen based on three drugs (taxol+carboplatin/cisplatin+etoposide) and two drugs (carboplatin/cisplatin+etoposide) on the combined small cell lung cancer (CSCLC). Methods:A retrospective study was conducted based on the data of 62 CSCLC patients who were admitted to and treated at Tianjin Medical University Cancer Institute and Hospital between July 2000 and April 2013. Of the 62 patients, 19 received the three-drug regi-men and 43 received the two-drug regimen. All patients received at least two cycles of chemotherapy and completed follow-up proce-dures. For each patient, the therapeutic efficacy was evaluated every two cycles, and toxicity was evaluated every cycle. Results:The response rates between the three-drug and two-drug groups were statistically significant (90%vs. 53%, P=0.033). However, no statisti-cal differences were observed in the disease control rate between the two groups (100% vs. 86%, P=0.212). The three-drug regimen could induce a better median progression-free survival compared with the two-drug regimen, but with no statistical significance (10.5%vs. 9.8%, P=0.484). Similarly, no statistical differences were noted in the median overall survival between the three-drug and two-drug groups (24.0%vs. 17.5%, P=0.457). The incidence rates of grade IV bone marrow depression and the termination of the original regi-men owing to severe adverse reactions were both significantly higher in the three-drug group than in the two-drug group (26.3% vs. 7.0%, P=0.036;31.6%vs. 14.7%, P=0.004). Conclusion:The two-drug regimen had almost the same survival rate and lower toxicity compared with the three-drug regimen. When using the TEP/TCE regimen, a close attention should be focused on its adverse reactions. The findings of this work showed that the two-agent regimen should be one of the standard treatments for CSCLC.

Objective To study the role of total flavonoids of hippophae rhamnoides in improving contactile function of stretched cardiac myocyte.Method Flavonoids were given to stretched myocytes which were proved their contractile function decline and then myocyte contractile mechanics characteristics and calcium transfer were measured.Result Flavonoids increased myocyte contractility,as indicated by myocyte shortening,velocity of shortening,peak+dL/dt and peak-dL/dt during shortening,in a concentration-dependent manner (r>0.9,P<0.001),and with no relation to the intracellular calcium transfer in the myocytes.Conclusion Flavonoids of the traditional Chinese drug hippophae rhamnoids is effective in improving the contractile function of stretched cardiac myocyte in low dosage.

Objective To investigate the effects of different concentrations of isoflurane on viability in rat primary cortical neurons. Methods Primary cortical neurons were isolated from neonatal Wistar rats (less than 24 h after birth) and exposed to 0.6 %, 1.2 % and 2.4 % isoflurane for 1, 2, 4, 8, 12 or 24 h, cell viability was evaluated by MTT reduction and LDH release assays. Changes in intracellular [Ca2+]i were detected by real-time confocal microscopy after the neurons were exposed to different concentrations of isoflurane. Results Exposure to 0.6% isoflurane for 24 h significantly increased viability of the primary rat cortical neurons as shown by decrease in LDH release and increase in MTT and elevation of peak [Ca2+]i. Exposure to 1.2% isoflurane for 12 or 24 h and to 2.4% isoflurane for 8, 12 or 24 h significantly reduced viability of cortical neurons associated with high and fast elevation of peak [Ca2 +] i. Conclusion Exposure to 0.6 % isoflurane increases viability of the primary rat cortical neurons. Exposure to 1.2% isoflurane and to 2.4% isoflurane decreases cell viability and the mechanism may be related to the changes in calcium concentrations in the neurons.
