OBJECTIVE:To observe the occurrence of paclitaxel(PTX)-induced muscle soreness and therapeutic efficacy and safety of diclofenac sodium. METHODS:Among 84 patients with malignant tumor receiving PTX chemotherapy,56 patients suf-fered from PTX-induced muscle soreness,among which 22 female patients suffered from medium and severe muscle soreness and then were randomly divided into group A and B,with 11 cases in each group. Group A was given Diclofenac sodium sustained-re-lease tablet 75 mg orally,once a day;group B was given Paracetamol and tramadol hydrochloride tablets one tablet orally,once a day,and then given Promethazine hydrochloride injection 100 mg subcutaneously,2-3 times a day when muscle soreness could not be born. Treatment course of both groups lasted for 5 d. The distribution of muscle soreness were observed. The onset time and dura-tion of muscle soreness were also observed as well as pain relief and the occurrence of ADR in group A and B. RESULTS:Among 84 cases,the incidence of muscle soreness was 66.67%,among which mild pain accounted for 23.81%,moderate pain accounted for 13.10%,and severe pain accounted for 29.76%. Among 56 patients with muscle soreness,earliest muscle soreness occurred on the day of medication,and most of muscle soreness occurred on 1-3 days after medication,mainly manifesting as sore,activity limitation when severe,associated with fatigue. The pain relief rate of group A and B were 100%,but the incidence of adverse re-actions in group A was significantly lower than group B,with statistical significances(P<0.05).CONCLUSIONS:Diclofenac sodi-um is similar to paracetamol and tramadol hydrochloride in the treatment of PTX-induced muscle soreness,but it is better than paracetamol and tramadol hydrochloride in safety.

The expectation about the direction of citrinin in the future was also discussed.

Cirrhosis with portal hypertension is a common disease which has a significant impact on the quality of patients' life. Esophagogastric devascularization (EGDV) has been demonstrated to be an effective method to treat portal hypertension, however certain complications are associated with it. The purpose of this study was to evaluate the effectiveness and clinical outcome of the selective EGDV (sEGDV) for the treatment of portal hypertension. The study was conducted prospectively from Jan. 1 2011 to Dec. 31, 2012, and 180 patients were randomized to the sEGDV group (n=90) or the non-sEGDV (n-sEGDV) group (n=90). Patients' demographics, preoperative lab test results and operative details were comparable between the two groups. Postoperative and short-term complications were analyzed in two groups. There was statistically significant difference (P<0.01) in the PVF reduction between the two groups. Post-operative complications showed no statistically significant difference between the two groups in the incidence of bleeding, ascites, acute portal vein thrombosis, fever and hepatic encephalopathy. Mortality between two groups was comparable. The incidence of splenic fossa effusion after the surgery was lower in sEGDV group than in n-sEGDV group. There were no significant differences in the short-term follow-up data such as esophageal varices and portal hypertensive gastropathy (P>0.05). It is suggested that sEGDV is a safe, simple and effective surgical procedure. It has both the advantages of the shunt and devascularization because it preserves body's voluntary diversion. With the advantage of low incidence of postoperative complications, it is an ideal surgical approach for the treatment of portal hypertension.
