Objective To observe the effect of electroacupuncture on migraine. Methods 60 patients were divided into electroacupuncture group (30 cases) who received electroacupuncture, and control group (30 cases) who received local nerve block. Results In the electroacupuncture group, 22 (73.33%) cases were cured, 6 (20.00%) cases were obviously improved, 2 (6.67%) cases were improved. While in control group, 17 (56.67%) cases were cured, 5 (16.67%) cases were obviously improved, 8 (26.67%) cases were improved. There was significant difference between these two groups (P<0.05). The time of treatment was less in the electroacupuncture group than in the control (P<0.05). Conclusion Electroacupuncture is effective on migraine.

Objective To study clinical value of percutaneous intrabiliary expandable metallic biliary stenting (EMBS) for treatment of malignant obstructive jaundice. Methods One hundred and sixty patients with malignant obstructive jaundice were treated with EMBS ( EMBS group) . Thirty patients underwent only external drainage by PTCD were recruited as control. The patency rate of stent,decline of bilirubin and the complication were analyzed retrospectively. Both groups were followed up for three months. The Kaplan-Meier method (log-rank test) was used to compare the survival period between the two groups. Results Anorexia,skin pruritus and color of urine alleviated at a certain degree in both groups.In the EMBS group,plasma total bilirubin was(218. 78 ±2. 29) μmol/L pre-stent,and decreased to (134. 90 ±2. 34), (83. 18 ±2.40) , (40. 74 ±2. 29) μmol/L at the 7,14,21 days after the stenting, respectively; direct bilirubin was (128.82 ±2.40) μmol/L pre-stent, and decreased to (81.28 ± 2. 34), (51. 29 ±2. 45) and (25. 70 ±2.40)μmol/L at the 7,14,21 days after the stenting ( P =0. 000). In the PTCD group,plasma total bilirubin was (223. 57 ± 2. 58) μmol/L pe-stent, and decreased to ( 145. 68 ± 2. 57 ) ,(87.57 ±2.58) ,(38.65 ±2. 20) μmol/L at the 7,14,21 days after the stenting,respectively;direct bilirubin was (127. 6 ±2. 59)μmol/L pre-stent,and decreased to (79. 78 ±2. 70) ,(58. 36 ±2. 46) and (29.46 ±2. 20)μmol/L at the 7,14,21 days after the stenting,respectively ( P <0.001 ). No significant difference was found between the two groups at any time point ( P > 0. 05). Complications occurred in 34 patients in the EMBS group and the incidence rate was 20. 62% . Two or more complications occurred in 9 patients. In the PTCD group, complications occurred in 60.00% of the patients. In the EMBS group, 14 patients were failed to follow up, and 136 died. The median length was 214 days. In the PTCD group,all patients were followed up and all died,with a median length of survival of 75. 5 days. The survival analysis showed that the EMBS group survived longer than the PTCD group (P =0. 000). Conclusions EMBS placement showed better effect than PTCD. Compared to PTCD, internal drainage of metallic stents lead few complications and faster recover, and can improve the life quality and prolong survival time of patient with malignant obstructive jaundice. The placement of metallic stents is recommended as a preference for palliative therapy of malignant biliary obstruction.

Conclusions The rehabilitation can improve the function of automatic nerve.

OBJECTIVETo explore the perioperative cardiovascular dysfunction and its relevance to age in patients with silent coronary heart disease (or silent myocardial ischemia), and explore the clinical treatment and recovery of perioperative arrhythmias.

METHODSOne hundred and eighty cases were selected from selective surgery patients with silent myocardial ischemia (SMI). Among the cases, 130 patients older than 51 years old were divided into 51 - 60 year-old group, 61- 70 year-old group and 71 - 80 year-old group. Control group was set up by other 50 patients younger than 51 years old. Electrocardiogram data of 24 h before the operation, 24 h after the operation and 48 h after the operation were continuously monitored by dynamic electrocardiogram (DCG). The electrocardiogram data of ST shifting, arrhythmia incidences of different type and at different time were analyzed by professional doctors. At the same time, the treatment and recovery of perioperative arrhythmia were recorded.

RESULTSAs the age increase, the magnitude and duration of ST shifting appeared upward trend compared to the control group (P < 0.05, P < 0.01). The incidence of ST elevation in 71 - 80 year-old group was higher than the control group (P < 0.05). The ST depression duration in 61 - 70 and 71 - 80 year-old group and ST elevation magnitude in 71 - 80 year-old group were higher than 51 - 60 year-old group (P < 0.05). Compared to the control group, the incidence of accelerated idioventricular rhythm (AIR) in 61 - 70 year-old group and the incidence of sinus bradycardia (SB), ventricular premature beat (VPB), ventricular tachycardia (VT) in 71 - 80 year-old group were higher (P < 0.05, P < 0.01). Compared to the 51 - 60 year-old group, the incidence of atrial fibrillation (AF) in 61 - 70 year-old group and the incidence of VP, VT, AF in 71 - 80 year-old group were higher (P < 0.05, P < 0.01). The arrhythmia incidences in 24 h after operation were higher than 48 h after operation and 24 h before operation (P < 0.01). As the age increase, the recovery incidence by removing inducement was decreased, but the recovery incidences by drug and electric-shock treatment were increased (P < 0.05).

CONCLUSIONOld SMI patients have high levels of perioperative myocardial ischemia and arrhythmia, and 24 h after operation is the period of high incidence.

BACKGROUND:Matrix metal oproteinase-13 is most active in the degradation of col agen type II in the extracel ular matrix of cartilage. Interleukin-1 (IL-1) is thought to be the inducer of matrix metal oproteinases, and participates in the degradation and degeneration of articular cartilage. OBJECTIVE:To study the influence of IL-1βon microRNA-27b (miR-27b) and matrix metal oproteinase-13 expression of chondrocytes in rats. METHODS:Chondrocytes isolated from seven male Wistar rats were cultured and divided into IL-1βstimulation group and control group. No stimulus was given in the control group;10μg/L of serum free medium was used to culture rat chondrocytes in the IL-1βstimulation group. Cel growth was observed at 0, 24, and 48 hours under an inverted microscope. miR-27b and matrix metal oproteinase-13 expression in the cultured chondrocytes were detected. RESULTS AND CONCLUSION:The relative expression of matrix metal oproteinase-13 in rat chondrocytes was gradual y increased when induced by IL-1βat 0, 24, and 48 hours (P<0.05). Expression of miR-27b and miR-31 in rat chondrocytes at 24 and 48 hours induced by IL-1βgradual y decreased (P<0.05);conversely, expression of MiR-26a, miR-26b, miR-23, and miR-204 gradual y increased (P<0.05). After 48 hours of IL-1βinduction, expression of miR-27b was the lowest in rat chondrocytes (P<0.05). These findings suggest that IL-1βinhibits miR-27b expression, strengthens the expression of matrix metal oproteinase-13, and damages chondrocytes, contributing to both the onset and progression of osteoarthritis.
