Vascular calcification (VC) is a chronic systemic vascular disease characterized by abnormal deposition of hydroxyapatite minerals in the vascular system and is closely associated with aging, diabetes, atherosclerosis, and chronic kidney disease. Perivascular adipose tissue (PVAT), a special type of adipose tissue that surrounds blood vessels, is thought to be a supportive component of the vascular structure and is capable of playing a role in homeostatic regulation during vasodilatation and contraction. Currently, there is growing evidence that perivascular adipose tissue acts as an endocrine and paracrine organ and interacts closely with cellular components of the vascular wall, which may be involved in the development of vascular calcification. This article reviews the role of perivascular adipose tissue in the pathophysiological process of vascular calcification and its potential as a target for therapeutic intervention, with the aim of providing new ideas for the prevention and treatment of vascular calcification.

OBJECTIVETo evaluate clinical efficacy of electroacupuncture at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery on postoperative pain and discomforts in patients with mixed hemorrhoids.

METHODSOne hundred and twenty cases of mixed hemorrhoids who received Milligan-Morgan operation were randomly divided into an electroacupuncture group, a sham electroacupuncture group and a blank group, 40 cases in each one. At the same time of basic treatment, the electroacupuncture was applied at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery in the electroacupuncture group, while shallow needling without electrical stimulation at sham acupoint (1 cm next to acupoint) was applied 30 min before surgery in the sham electroacupuncture group, while no treatment was given before the surgery in the blank group. The total dose of painkillers in the first 24 h after operation, the number of cases who received additional anesthetic in the operation, the self-score of most severity pain in the first 24 h after operation and sleeping time in the night of surgery were observed.

RESULTSThe differences of the numbers of cases who received additional anesthetic in the operation had no statistical significance among the three groups (all P > 0.05), but compared with the sham electroacupuncture group and blank group, the total dose of painkillers in the first 24 h after operation was reduced in the electroacupuncture group [(2.43 +/- 1.08) tablets vs (3.23 +/- 1.33) tablets, (3.10 +/- 1.22) tablets], and the score of most severity pain was also decreased (6.65 +/- 1.00 vs 7.48 +/- 0.96, 7.25 +/- 1.19), besides, the sleeping time in the night of surgery was increased [(220.63 +/- 85.50) min vs (162.00 +/- 92.69) min, (151.50 +/- 80.01) min, all P < 0.05].

CONCLUSIONThe electroacupuncture at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery has effects of preemptive analgesia on postoperative pain for patients with mixed hemorrhoids.

Objective To explore the expression of Survivin in colorectal cancer tissue and its relationship with clinicopathological features.Methods In situ hybridization was used to examine the expression of Survivin mRNA,and immunohistochemical method was used to detect the expression of Survivin protein in 60 cases of colorectal cancer and 30 cases of colorectal normal mucos tissue.The relationship of the expression of Survivin protein with clinicopathological features of colorectal cancer was analyzed.Results The positive expression rate of Survivin protein in colorectal normal mucos tissue (10.00％,3/30) was lower than that in colorectal cancer tissue (73.33％,44/60),and there was significant difference (P ＜ 0.05).The positive expression rate of Survivin mRNA in colorectal normal mucos tissue (6.67％,2/30) was lower than that in colorectal cancer tissue (63.33％,38/60),and there was significant difference (P ＜ 0.05).The expression of Survivin mRNA was positively correlated with depth of invasion,lymph node metastasis,liver metastasis,peritoneal micrometastasis and TNM stage in patients with colorectal cancer (P ＜ 0.01),but had no correlation with gender,age,tumor size,location,degree of differentiation and histological type (P ＞ 0.05).Conclusions The specific high expression of Survivin protein has a high correlation with the occurrence,development,infiltration of colorectal cancer.Survivin may be used as a marker for prognosis of patients with colorectal cancer.

The theoretical basis of the alcohol precipitation process control was provided, the alcohol precipitation was optimized and the relationship equation was got. The monod glycoside, loganin and paeoniflorin were used as the evaluation indexes to determine the impact factors of alcohol precipitation techniques of Liuwei Dihuang decoction by the Plackett-Burman experimental design and the levels of non-significant factors were identified. Then, Box-Behnken response surface methodology was used to research and discuss the critical process parameters influence the effect of alcohol precipitation and draw interaction between key process parameters and the correlation equation with index components.

Objective To evaluate the efficacy and safety of oxycodone hydrochloride injection for postoperative analgesia in patients undergoing the operation under general anesthesia in a prospective,randomized,blind,multicenter,positive-controlled,clinical trial.Methods Two hundred and forty ASA Ⅰ or Ⅱ patients of both sexes,aged 18-64 yr,weighing 40-95 kg,scheduled for elective abdominal operation or orthopedic surgeries under general anesthesia,were randomly divided into 2 groups (n =120 each):morphine sulfate injection group (group M) and oxycodone hydrochloride injection group (group O).Morphine or oxycodone 1 mg was injected intravenously when the patients complained of pain after tracheal extubation or removal of the laryngeal mask,and administration was repeated if necessary until VAS≤40 mm.Then patient-controlled intravenous analgesia (PCIA) (100 ml,0.5 mg/ml) with morphine or oxycodone was used for postoperative analgesia (lasting for 48 h).The PCIA pump was set up with a 1 ml bolus dose,a 5 min lockout interval and background infusion at a rate of 0.5 mg/h.Pain at rest and during movement was assessed using VAS score at 3,24 and 48 h after administration,and non-inferiority test was performed.Total morphine or oxycodone consumption,requirement for rescue analgesic,the number of unsuccessfully delivered dose,the number of attempts,and the level of patient' s satisfaction were recorded within 48 h after operation.The adverse events were recorded and laboratory examinations (blood and urine routine test,blood biochemical examination) were performed within 72 h after administration.Results There was no significant difference in the VAS scores at rest and during movement at different time points,requirement for rescue analgesic,the number of unsuccessfully delivered doses and attempts,level of patient' s satisfaction,total morphine or oxycodone consumption,and adverse events between the two groups (P ＞ 0.05).No serious adverse event occurred in the two groups.The most common adverse event was nausea,followed by vomiting.There was no significant difference in the incidences and degree of nausea and vomiting between the two groups (P ＞ 0.05).The incidences of nausea and vomiting in patients underwent orthopedic surgeries were significantly lower in group O than in group M (P ＜ 0.05).The other adverse events were fewer and abnormal laboratory examinations were rare in the two groups.95％ confidence interval of the difference between the mean VAS scores at rest and during movement at each time point was within 15 mm (boundary values of non-inferiority testing) in the two groups.Conclusion PCIA with oxycodone hydrochloride injection is safe and effective in reducing pain after moderate or major operation,and the analgesic efficacy is similar to that of morphine sulfate injection,however,the development of nausea and vomiting is reduced when PCIA with oxycodone hydrochloride injection is used for orthopedic surgeries as compared with that when morphine sulfate injection is used and the ratio between the analgesic efficacy of the two drugs is close to 1∶1.

ObjectiveTo study the role and mechanism of resisitin in prophylactic and therapeutic treatments of rosiglitazone,a specific peroxisome proliferator-activated receptor-γ(PPARγ) ligand,in rats with severe acute pancreatitis (SAP) and pancreatitis-associated pulmonary injury.MethodsThe levels of amylase ( AMY ),Resistin,TNF-α,IL-1 β and C reactive protein (CRP) in blood plasma,lung myeloperoxidase ( MPO ) activity,pancreas/body weight ratio and lung wet/dry weight ratio were evaluated.Pancreatic and pulmonary pathology were observed.The expression of resistin in pancreas was detected byimmunohistochemistry.The gene expression of resistin mRNA was investigated by real-time PCR.ResultsBoth prophylactic and therapeutic treatments with rosiglitazone could obviously ameliorate the levels of AMY,resistin,TNF-αt,IL-1β and CRP ( all P ＜ 0.01 ).Compared with the control group,both prophylactic and therapeutic treatment groups were higher( all P ＜ 0.01 ).The prophylactic treatment group was not different from the therapeutic treatment group.Both prophylactic and therapeutic treatments with rosiglitazone could significantly reduce pancreas/body weight ratio,pancreatic pathology,MPO,pulmonary pathology ( all P ＜ 0.01 ).Compared with the SAP group,the expression of resistin mRNA in the prophylactic and therapeutic treatment groups were obviously decreased.ConclusionRosiglitazone could obviously ameliorate pancreatitis and pulmonary injury induced by L-arginine.
