Journal of Integrative Medicine 2012;10(12):1490-6
Acupuncture is widely used in clinics to suppress chronic visceral pain in patients with irritable bowel syndrome (IBS); however, the exact neurobiological mechanisms for its therapeutic effects need further exploration. The aim of this study was to investigate the possible involvement of spinal neurons in the effects of electroacupuncture (EA) in relieving chronic visceral hyperalgesia in a rat model of IBS.

Acupuncture has been clinically proved to be effective in treating abdominal pain in patients with irritable bowel syndrome (IBS). However, its neurobiological mechanism remains largely unexplored. The aim of this study was to investigate the effect of electroacupuncture (EA) in relieving chronic visceral hyperalgesia and the possible involvement of N-methyl-D-aspartate receptor 1 (NR1) in rostral ventromedia medulla (RVM) of the brain in an IBS rat model.

Dopamine(DA) modulates diverse wake-related behaviors including movement,reward, and cognition.Dopaminergic neurons are located in the substantia nigra pars compacta and ventral tegmental area.There are five distinct DA receptors(R):D_1R,D_2R(D_(2S)R and D_(2L)R), D_3R,D_4R and D_5R in the central nervous system, in which D_1R and D_2R are majorly expressed. The affinity of D_2R for endogenous DA is significantly higher than that of D_1R.Re- cently,studies by pharmacological and gene knock-out animals revealed that dopamine D_2R is essential inmaintaining wakefulness.Here,we review the progress on roles of D_2R in sleep-wake regulation.

Objective To clarify the correlation of alpha fetoprotein (AFP) half-life (T1/2) with relapse or/and metastasis of primary hepatocellular carcinoma (PHC) after treatment. Methods Determination of AFP content in serum with two steps double McAb sandwich ELISA.Calculation AFP T1/2 of the sufferers treated with intervention and radiofrequency ablation (RFA) according to T1/2=0.3 dT/log(AFP1/AFP2). Results When AFP T1/2>11.5 days, the sensitivity, specificity and accuracy of predicting the relapse or metastasis of PHC after treatment were 87.5%, 89.3%, 88.5%, respectively. Intervention group was 82.35%, 83.3%, 82.75%, respectively and RFA group was 93.3%, 93.75%, 93.5%, respectively. During 200 days,there was very significant difference of AFP T1/2 (P<0.001) between non-relapsed/ non-metastasized and relapsed, metastasized and died. Conclusions AFP T1/2 can be used as a predictive index for relapse, metastasis of PHC after treatment. It is not only a reliable parameter for the later stage treatment, but also a useful index for the evaluation of effect.

Objective To investigate the value of echocardiography for assessing the right ventricular function before and af ter treatment in the patients with pulmonary embolism.Methods Ninety-six patients with pulmonary embolism in our hospital from June 2014 to December 2015 were selected as the research subjects and divided into low-risk group,intermediate-risk group and high-risk group according to the disease severity.The echocardiographic examination was performed before and after treatment in all cases.Results The pulmonary artery systolic pressure after treatment in the low-risk group was lower than that before treatment (P<0.05).The transverse diameter of right ventricle,transverse diameter of right ventricle and pulmonary artery systolic pressure after treatment in the intermediate-risk group and high-risk group were lower than those before treatment (P<0.05).The Tei index after treatment in the low-risk group,intermediate-risk group and high-risk group was lower than that before treatment (P< 0.05).The right ventricle ejection fraction (RVEF),right ventricular end-systolic volume (RVESV) and right ventricular end-dias tolic volume (RVEDV) in the low-risk group had no statistically significant difference between before and after treatment.RVEF after treatment in the intermediate-risk group and high-risk group was higher than that before treatment(P<0.05),while RVESV and RVEDV after treatment were lower than those before treatment (P<0.05).Conclusion Echocardiography can objectively re flect the change situation of right heart function before and after treatment in the patients with pulmonary embolism,and can be used as an evaluation method for the effect of pulmonary embolism treatment.

Objective To evaluate the clinical significance of detecting urinary natural killer(NK) cells in patients with general types of glomerulonephritis. Methods The contents of urinary NK cells from 54 patients with glomerulonephritis were measured by flowcytometry,while all patients were classified into two groups including acute proliferation group and none-acute proliferation group by renal biopsy results. The content of urinary NK cells was compared between the two groups. Results The content of urinary NK cells in acute proliferative glomerular disease group were( 14. 8 ±3. 3)% (30 cases) ,which was significantly higher than that of(21. 6 ±2. 9)% (24 cases) in the non-acute proliferative glomerular patients(P<0.05). Conclusions Decreasing of the contents of NK cells in urine may be an indirect indicator of the activity of glomerulonephritis.

Objective To investigate clinical features, diagnosis, and treatment of refractory Mycoplasma pneumoniae pneumonia (MPP) combined with thrombosis. Methods One case with refractory MPP associated with thrombosis was retrospectively analyzed with literature review. Results The patient presented with respiratory symptom at the onset, while melosalgia and decreased respiratory sound in left lung were occurred during anti-infection therapy. Thereafter, thrombosis of lower extremity veins and pulmonary embolism were confirmed by a series of examinations. Serum anti-phospholipid antibody was positive. Finally, the patient was treated with a combination of anticoagulation and immunosuppressive therapies. Conclusions The mechanism of refractory MPP combined with thrombosis may be associated with excessive inflammatory response and endothelial cells injury. The thrombosis complication should be suspected in patient of Mycoplasma pneumonia infection with positive anti-phospholipid antibody and low concentration of protein C and immunosuppressive therapy should be implemented promptly.

Objective:To investigate the correlation between Duke treadmill score (DTS) and corrected thrombolysis in myocardial infarction frame count(CTFC)in patients with coronary atherosclerotic heart disease(CAD). Methods:Seventy-two patients with coronary atherosclerotic heart disease, who underwent treadmill exercise tests in 2 weeks before coronary angiography were enrolled in our study. All the patients were divided into 2 groups according to the value of DTS: low-risk group (DTS≥5) and moderate-high-risk group (DTS

Objective To investigate the safety and short-term outcome of rotational atherectomy followed by drug-eluting stenting in heavily calcified coronary long lesions. Methods From Jan 1, 2011 to May 31, 2016, 109 cases with 114 heavily calcified coronary lesions which were treated with rotational atherectomy followed by drug-eluting stenting in Peking University People's Hospital were included. They were divided into diffuse lesion group ( lesion ≥25 mm, 68 cases, 72 lesions ) and focal lesion group (lesion ﹤25 mm,41 cases, 42 lesions). All patients were followed up in hospital. Procedure parameters, procedural complications ( dissection, perforation, slow flow/no flow and procedural related myocardial infarction),procedural success and major adverse cardiovascular events (cardiac death, non-fatal myocardial infarction and stent thrombosis) were analyzed. Results The procedural success rate was 98. 5%(67/68) in diffuse lesion group and 100% ( 41/41 ) in focal lesion group ( P=0. 453 ) . Complication rates did not differ between the two groups (41. 2% and 34. 1%, P=0. 673). Major adverse cardiovascular events rates were 41. 2% and 31. 7%, P =0. 484. Conclusions Treating coronary lesions ≥25 mm in length with rotational atherectomy followed by drug-eluting stenting does not impact the short-term outcome when treating carefully and correctly . Procedural success rate and in-hospital outcome is satisfactory.
