Objective To observe the clinical efficacy of Kuijiening Paste acupoint application on ulcerative colitis (UC) patients of spleen-kidney Yang deficiency type, and its effect on serum levels of IFN-γand IL-4. Methods Sixty UC patients were divided into treatment group, control group and combined treatment group, 20 cases in each group, and were given Kuijiening Paste acupoint application plus placebo, oral sulfasalazine plus comfort paste and Kuijiening Paste acupoint application plus sulfasalazine respectively for 60 days. The clinical efficacy, mucosal lesions efficacy, mucosal pathology efficacy, changes of serum IFN-γand IL-4 were observed after treatment. Results There was no significant difference in clinical efficacy, mucosal lesions efficacy and mucosal pathology efficacy among the three groups (P>0.05). After treatment, IFN-γlevels of the three groups significantly reduced, and IL-4 levels significantly increased (P<0.01). The difference between the treatment group and the control group was significant (P<0.05). The difference between the combined treatment group and the control group was significant (P<0.01). Conclusion Kuijiening Paste acupoint application combined with sulfasalazine can regulate the level of immune cytokine in UC patients of spleen-kidney Yang deficiency type, and receive good clinical efficacy.

Objective To study the effect of folic acid on decreasing level of plasma total homocysteine(tHcy)in patients with sudden sensorineural hearing loss(SSHL) and the optimal dosage of folic acid. Methods Ten randomized controlled trials involving treatment data on 210 patients with SSHL were retrospectively studied.They were divided into seven groups according to the daily dosage of folic acid: group A to group G,0.2 mg,0.4 mg,0.8 mg,2.0 mg,5.0 mg,10.0 mg and 15.0 mg,respectively.Besides oral administration of folic acid,Vitamine B6 and B12were supplemented,and other routine treatment were performed.Fluorescence polarization immunoassay was employed to detect the plasma tHcy before and 3 months after the treatment.And the data of plasma tHcy of 210 patients without SSHL were collected and served as controls.The levels of plasma tHcy were statistically analysed between the SSHL group and control group and among group A to group G. Results The level of plasma tHcy in the SSHL group was significantly higher than that in the control group,(18.07?1.58)?mol/L vs(13.63?1.33) ?mol/L(P0.05). Conclusion The levels of plasma tHcy are significantly increased in SSHL.Folic acid may play an important role in decreasing the levels of tHcy in patients with SSHL,and a dosage of 10 mg/d for oral adminstration is well suggested.

Objective To investigate the effect of acupuncture at point Neiguan on mouse myocardial hypertrophy.Methods Thirty-sixty healthy C57BL6 mice were randomized into blank, model and treatment groups, 12 rats each. In the treatment group, an acupuncture needle was inserted into point Neiguan and retained for 15 min, once daily. After nine days of treatment, the ratios of cardiac weight/tibial length were compared between the groups. Left ventricular myocardial tissues were processed by Masson trichrome staining in every group of mice. The differences in myocardial fiber arrangement and collagen fiber distribution between the groups were observed under the ordinary optical microscope in 100 times of field of vision. Sarcomere structure, myofibril arrangement, collagen fibers and mitochondria in injured myocardial tissues were observed by transmission electron microscopy. Results Heart rate increased significantly in the model group and decreased significantly in the acupuncture group compared with the blank group. Cardiac weight and the ratios of cardiac weight/tibial length increased significantly in the model and acupuncture groups compared with the blank group (P<0.01) and decreased significantly in the acupuncture group compared with the model group (P<0.01). In the model group, myocardial tissues had compensatory hypertrophy with incontinuous status, and myocardial transverse striations had severe disorder/disruption, karyopyknosis appeared and cytoplasmic eosinophilic change became obvious in few of the rats. The results were better in the acupuncture group than in the model group. In the model group, part of myofibrils had focal fusion, interstitial collagen fibers proliferated and mitochondria had swelling and compensatory increase. The results were also better in the acupuncture group than in the model group.Conclusions Acupuncture at point Neiguan can reduce the production of collagen fibers and mitochondria, improve the arrangement of sarcomere structure and delay the progression of myocardial hypertrophy.

Objective To investigate the association of chest pain patients with primary level in high-sensitivity troponin T (hs-cTnT) level no more than 14 ng/L in the onset of acute myocardial infarction in pa-tients with chest pain. Methods We enrolled 3 096 participants from January 2012 to December 2013 in West China Hospital, Sichuan University. All patients were classified two groups (hs-cTnT > 14 ng/L, hs-cTnT ≤14 ng/L and no ischemia on ECG) according to hs-cTnT levels and ECG. We evaluated the risk of myocardial in-farction and death and negative predictive value in 30 days. Results Thirty-seven patients were diagnosed in having acute myocardial infarction (AMI) and 4 patients were dead in the hs-cTnT > 14 ng/L group in 30 days in the absolute risk 2.35(1.86-2.74) and 0.29(0.12-0.53); 9 patients were diagnosed as having AMI and no patients were dead in the hs-cTnT ≤ 14 ng/L group in 30 days in the absolute risk 0.58 (0.42-0.74). Conclu-sion Chest pain patients whose primary levels no more than 14 ng/L in hs-cTnT with no ischemia on ECG can be ruled out AMI in negative predictive value 99.6%. the levels of hs-cTnT which were dynamic monitored at least 5 h and still no more than 14 ng/L can rule out AMI directly.
