Objective To explore the effects of lycopene on interleukin-6 (IL-6) expression and motor function after spinal cord injury in rats. Methods 36 healthy adult Sprague-Dawley rats were randomly divided into control group (A), methylprednisolone sodium succinate (MP) treatment group (B) and lycopene treatment group (C) with 12 rats in each group, and spinal cord injury model at T9 was established with modified Allen's technique (10 g×25 mm). 30 minutes after modeling, group A received no treatment, group B was injected MP 30 mg/ kg, group C was given lycopene 20 mg/kg. They were tested with inclined plate test 1 day, 3 days and 7 days after injury. The expression of IL-6 was examined with immunohistochemistry, then. Results The inclined plate test scores were higher in the group C than in the group A 1 day and 7 days after injury (P<0.05), and in the group B than in the group A 1 day, 3 days and 7 days after injury (P<0.05). The expression of IL-6 was significantly lower in the groups B and C than in the group A 1 day, 3 days, 7 days after injury (P<0.001). Conclusion Lycopene can inhibit the expression of IL-6 in acute spinal cord injury to reduce the inflammation and facilitate the recovery of nerve and motor function.

OBJECTIVETo compare the differences in the clinical efficacy between Guan's quadruple therapy for kidney disease and the conventional western medication in the treatment of chronic renal failure (CRF).
METHODSEighty patients were randomized into an observation group and a control group, 40 cases in each one. In the observation group, besides the physician instruction of low protein and low phosphorus diet in the two groups, Guan's quadruple therapy for kidney disease was applied, including (1) the isolated herbal moxibustion at Shenshu (BL 23) and Pishu (BL 21), or Ganshu (BL 18), Zusanli (ST 36) and Guanyuan (CV 4) alternatively; (2) acupuncture at the auricular points such as shen (CO10), jiaogan (AHR6), Shenshangxian (TG2), fei (CO14) and pizhixia (AT4); (3) injection of mixture of astragalus injection and lidocaine injection at Feishu (BL 13), Pishu (BL 21), Shenshu (BL 23) and the others; (4) modified Shenshuai Yihao decoction according to syndrome differentiation. In the control group, the conventional western medication was used. After 6 months of treatment, the differences were observed between the two groups in the clinical efficacy, serum creatinine (Scr), blood urea nitrogen (BUN), endogenous creatinine (Ccr) and 24 h urine protein quantitation (UPQ).
RESULTSIn the observation group, after treatment, the remarkably effective rate was 50.0% (20/40) and the total effective rate was 82.5% (33/40), which were superior to 25.0% (10/40) and 45.0% (18/40) in the control group (both P < 0.05). After treatment, the levels of Scr, BUN and 24 h UPQ were reduced apparently (all P < 0.05), and the level of Ccr was increased apparently in the two groups (both P < 0.05). After treatment, the levels of Scr, BUN and 24 h UPQ were reduced much more apparently in the observation group as compared with those in the control group (all P < 0.05).
CONCLUSIONGuan's quadruple therapy for kidney disease achieves a better efficacy on CRF compared with the conventional western medication. This therapy improves renal functions, relieves clinical symptoms and physical signs and benefits the life quality of patients.

BACKGROUND:Tranexamic acid is a synthetic anti-fibrinolytic drug, and can effectively control blood loss after total knee arthroplasty through vein. OBJECTIVE:To evaluate the effectiveness and safety of tranexamic acid in reducing blood loss after primary unilateral total knee arthroplasty. METHODS:From 2014 to 2015, 100 patients from the Department of Lower Limb, Sichuan Orthopaedic Hospital underwent primary unilateral total knee arthroplasty, and randomly divided into test group which used tranexamic acid and control group which used tranexamic acid, with 50 cases in each group. 1 g tranexamic acid was infused into the vein at 10 minutes before total knee arthroplasty in the test group, but tranexamic acid was not given in the control group. RESULTS AND CONCLUSION:The amount of total blood loss, postoperative wound drainage in 24 hours, and the amount of blood transfusion were significantly less in the test group than in the control group (P < 0.05). No significant differences in intraoperative blood loss and the number of patients receiving blood transfusion were found between the test and control groups. No significant difference in preoperative hemoglobin levels was detected before surgery, but hemoglobin levels were decreased after surgery between the two groups. Postoperative hemoglobin levels were apparently higher in the test group than in the control group after surgery. At 24 hours after surgery, no significant difference in coagulation was detectable between the two groups. At 6 days, double lower limb vein color Doppler ultrasound examination did not reveal deep vein thrombosis in both groups. These findings verify that treatment with tranexamic acid in the vein before primary unilateral total knee arthroplasty can evidently diminish the amount of perioperative blood loss and blood transfusion, reduce the risk and cost of blood transfusion, which is good for rehabilitation and does not increase the risk of deep vein thrombosis.

Objective To compare the difference of the clinical efficacy on post-stroke shoulder-hand syndrome treated by acupuncture at stellate ganglion and by conventional acupuncture. Methods Ninety cases of post-stroke shoulder-hand syndrome ( at stageⅠ or stageⅡ) were randomized into treatment group and control group, 45 cases in each group. Both groups received basic rehabilitation training. Additionally, the treatment group received acupuncture at the bilateral stellate ganglions of the neck, with reducing acupuncture by rotating the needles. The control group received the conventional acupuncture on Jiquan ( HT 1) , Chize ( LU 5) , Jianyu (LI 15), Quchi (LI 11), Shousanli (LI 10), Hegu (LI 4), with reducing acupuncture by lifting and thrusting the needle on Jiquan ( HT 1) and Chize ( LU 5) , and with mild reinforcing and reducong acupuncture on the other acupoints. The treatment for both groups was given once every day, and 14 times in total. The total syndrome scores, visual analogue scale (VAS) scores, modified Fugl-Meyer Assessment of motor function scale (FMA) scores, and modified Barthel index (MBI) were observed to evaluate the changes of symptoms, pain and motor function of the upper limbs, and activity of daily life before and after treatment in the two groups. The clinical efficacy was also compared between the two groups. Results The total syndrome scores, VAS scores, FMA scores and the modified Barthel index were improved apparently after treatment in the two groups (all P<0.01), and the improvement in the treatment group as more obvious (all P<0.01) . The total effective rate was 93.33% (42/45) in the treatment group, which was better than 73.33% (33/45) in the control group ( P<0.05) . During the treatment, patients of both groups had good compliance, and all completed the trial. No obvious adverse reaction was found in the two groups. Conclusion Acupuncture at stellate ganglion is effective and safe for the treatment of post-stroke shoulder-hand syndrome, and it has higher efficiency than the conventional acupuncture.

ObjectiveTo investigate the risk factors for contrast-induced nephropathy (CIN) after endovascular therapy in patients with peripheral arterial diseases and to evaluate the conformance of serum cystatin C (Cys C) and serum creatinine in diagnosis of CIN. Methods In this prospective,single center study,in-hospital patients with peripheral arterial diseases undergoing non-emergency endovascular therapy from July 2010 to April 2011 in our hospital were enrolled.CIN was defined asScr increase ≥25% after angiography.General clinical characteristics and blood biochemical parameters were compared between the non-CIN and CIN groups.Logistic regression analysis was performed to determine risk factors.Changes compared to baseline level in serum creatinine and Cys C at predefined time-points were evaluated.Results A total of 367 patients were enrolled in the study.The proportions of patients with diabetes mellims and treatment with diuretics before angiography,contrast-media dosage were significantly higher in the CIN group than those in non-CIN group (P<0.05,<0.01,<0.01).Logistic regression analysis indicated that diabetes mellitus,contrast-media dosage were risk factors for CIN.Several serum Cys C increase criteria at 24 hours after contrast media exposure all had low sensitivity for predicting a Scr increase ≥25%.Only small overlapped regions were found in Venn diagram between several increasing criteria according to serum Cys C and serum creatinine criterion. Conclusions Diabetes mellitus,contrast-media dosage are independent risk factors for CIN.The results of several increasing criteria according to serum Cys C in evaluating contrast-induced AKI are not coincident well with that of serum creatinine criterion.

Protein tyrosine phosphatase (PTP) 1B is a potential target for the treatment of diabetes and obesity. We have previously identified the benzoyl sulfathiazole derivative II as a non-competitive PTP1B inhibitor with in vivo insulin sensitizing effects. Preliminary SAR study on this compound series has been carried out herein, and thirteen new compounds have been designed and synthesized. Among them, compound 10 exhibited potent inhibition against human recombinant PTP1B with the IC50 value of 3.97 micromol x L(-1), and is comparable to that of compound II.

Complete resection of liver cancer is the main approach for achieving radical resection,and sufficient remnant liver is essential for avoiding hepatic failure after operation.With the aim of increasing remnant liver volume,a new two-stage technique,associating liver partition and portal vein ligation for staged hepatectomy (ALPPS),recently has been developed.In this article,the initial experience with 1 case of hepatocellular carcinoma who underwent ALPPS at the Zhongshan Hospital in April 2013 was reported.In the first stage,the right portal vein branch was ligated and subsequently the liver parenchyma was dissected along the falciform ligament to isolate the segment Ⅳ and the left lateral lobe.On postoperative day 7,the remnant liver volume was increased from 291 ml to 579 ml,and on postoperative day 8,the second stage operation was performed.During the second stage,the extended right lobe was removed.ALPPS induces a great and fast hypertrophy of the remnant liver,and R0 resection could be performed on patients which was considered unresectable because of small remnant liver volume,without severe postoperative liver failure and has a low mortality.

OBJECTIVETo compare the difference in the clinical efficacy on posterior circulation ischemia between acupuncture at stellate ganglion and conventional acupuncture as well as the impacts on blood pressure.
METHODSEighty cases of posterior circulation ischemia were randomized into an observation group (40 cases) and a control group (40 cases). In the observation group, acupuncture was applied to the bilateral stellate ganglions on the neck, stimulated with reinforcing technique by rotating the needles. In the control group, the acupuncture of reducing technique was applied to Fengchi (GB 20), Baihui (GV 20), Neiguan (PC 6) and Taichong (LR 3) in the excess syndrome. The even needling or reinforcing technique was applied to Fengchi (GB 20), Baihui (GV 20), Ganshu (BL 18), Shenshu (BL 23) and Zusanli (ST 36) for the deficiency syndrome. The treatment was given once every 3 days and 4 treatments were required totally in the two groups. The changes in total syndrome score, peak Systolic blood flow velocity (Vp) of vertebral artery and basilar artery, systolic and diastolic blood pressures were compared before and after treatment in the two groups. The clinical efficacy was compared between the two groups.
RESULTSThe total syndrome score was reduced apparently after treatment compared with that before treatment in the two groups (P < 0.01), and the reducing was more obvious in the observation group as compared with that in the control group (P < 0.01). The total effective rate was 87.5% (35/40) in the observation group, higher than 67.5% (27/40, P < 0.05) in the control group. After treatment, the reduced Vp of vertebral artery was not improved apparently as compared with that before treatment in the control group, Vp in blood velocity abnormality (including vascular spasm, stenosis or reduced velocity) of vertebral artery and basilar artery was all improved as compared with that before treatment in the two groups (P < 0.01), and the improvements in the observation group were more obvious than those in the control group (P < 0.01). After treatment, the systolic and diastolic pressures were reduced as compared with those before treatment in the two groups, and the reduced systolic and diastolic pressures in the observation group were more apparent than those in the control group (P < 0.01).
CONCLUSIONAcupuncture at stellate ganglion achieves the satisfactory efficacy in the treatment of posterior circulation ischemia and the significant efficacy of reducing blood pressure, more advanced than the conventional acupuncture.
