OBJECTIVE:To evaluate the clinical efficacy of liraglutide and insulin glargine in the treatment of type 2 diabetes mellitus (T2DM) and conduct pharmacoeconomic analysis, and to provide economical and reasonable T2DM treatment plan. METHODS:80 T2DM patients were randomized into liraglutide group and insulin glargine group,with 40 cases in each group. Both groups were given Metformin hydrochloride sustained-release tablet orally 0.5-2.0 g/d,and diabetes mellitus diet and sport training guide after oral antidiabetic drug withdrawal of previous treatment plan. Liraglutide group was given Liraglutide injection hypodermically,0.6-1.2 mg,qd;insulin glargine group was given insulin glargine hypodermically at 22 o’clock,initial dose of 0.2 IU/(kg·d),adjusted according to the levels of PG,FBG,nocturnal blood glucose level till FBG≤7 mmo1/L and 2 h PG ≤10 mmol/L in both group. Treatment course of 2 groups lasted for 12 weeks. The changes of FBG,2 h PG,HbA1c and BMI were ob-served in 2 groups before and after treatment. 2 therapy plans were evaluated and compared by cost-minimization analysis. RE-SULTS:After treatment,the levels of FBG,2 h PG and HbA1c decreased significantly in 2 groups,compared to before treatment, with statistical significance (P<0.05),but there was no statistical significant difference between 2 groups (P>0.05). After treat-ment,BMI of liraglutide group decreased significantly compared with before treatment and insulin glargine group,with statistical significance (P<0.05). There was no statistical significant difference in BMI of insulin glargine group before and after treatment (P>0.05). Cost-minimization analysis showed that the cost of insulin glargine group in reducing FBG,2 h PG and HbA1c were less than liraglutide group,but were more than liraglutide group in reducing BMI. Sensitivity analysis demonstrated the stability and reliability of cost-minimization analysis. CONCLUSIONS:Lira-glutide and insulin glargine have the same clinical efficacy,but insulin glargine need lower cost in blood glucose control,and liraglutide is better therapy plan for body weight control.

It was reported that a complete antifertility action of alpha-chlorohydrin in combination with glycidol in male rats after a daily oral dose of 5mg/kg and 75mg/kg respectively for two days. Simultaneously some ultrastructural changes including mitochondrial swelling, atrophy of Golgi complex, decreasing in pinocytotic vesicles and stereocilia were found in principal cells of epididymis within 3 days after medication.In this experiment the animals received 3, 6 and 9 courses of treatment respectively, each course included two days of administration with a daily dose mentioned above and eight days of cessation of medication.The specimens of initial segment of epididymis, liver and kidney were taken at the end of 3 rd, 6 th and 9th courses of treatment for electron microscopy.The principal cells of initial segment of epididymis revealed a normal feature at the end of 3 rd and 9 th course of treatment. But at the end of 6 th course of treatment, the atrophy of Golgi complex and the decrease in stereocilia and pinocytotic vesicles were found in some principal cells.Any ultrastructural changs of sperms in the initial segment were not found by electron microscope.There was also mitochondrial changes with striking increase in the density of the matrix and reduction of size in some liver cells at the end of 6 th course of treatment, but not at the end of 3 rd or 9 th course of treatment. The epithelial cells of nephron in all the specimens revealed a normal ultrastructural feature.The results suggest that the ultrastructural changes of the principal cells and the liver cells induced by the mixture of the drugs could be recovered at the end of treatments.

Combined effects of ?-chlorohydrin and glycidol on the ultrastructure of theinitial segment and the tail region of the rat epididymis have been studied by ultra-thin sections under electronmicroscope.Individual effects of the both drugs on thesame tissues were also examined simultaneously.The major results are as follows.1.Numbers of swollen and degenerated mitochondria were observed in principalcells,clear cells,apical cells and basal cells of epididymal epithelium,as well as insmooth muscle cells of the ductus epididymidis and in endothelial cells of the capil-laries in epididymal interstitium during a period of 3~30 days after administrationof low dose of ?-chlorohydrin combined with glycidol(5 mg ?-chlorohydrin plus75mg glycidol/kg/day?2),which previously has been proved to be effective inmale rat antifertility.Additionally,Golgi vacuoles,pinocytotic vesicles,multivesicularbodies,stereocilia and smooth endoplasmic reticulum in the apical cytoplasm of someprincipal cells occasionally were found to decrease in number.No Morphologicalchanges of the nuclei were found in these affected cells.The number of morphologi-cally unchanged mitochondria appears to become more with extended time after drugswithdrawal.2.In the group treated with the large combined dose of the drugs(20 mg ?-chlorohydrin plus 100 mg glycidol/kg/day?2),apart from the changes mentionedabove,necrosis and exfoliation of some epididymal epithelial cells could be found.Some lesions of the sperm,such as the destruction of the cytoplasmic membrane,swelling of mitochondria and pyknosis of nucleus were present in a few specimenstaken from this group.3.Effects similiar to that of the combined use of the drugs were also found ingroups using ?-chlorohydrin or glycidol alone,but a less degree of lesions revealed.These observations suggested that the antifertile effects of ?-chlorohydrin andglycidol either used in combination or alone could result injury of mitochondria inepididymal epithelial cells,which should lead to the decrease of the function ofepididymis,hence to interfere with the maturation of the sperm in it.

Objective:To evaluate the efficacy and safety of thalidomide on preventing and treating radiation-induced oral mucositis (RIOM) in nasopharyngeal carcinoma (NPC). Methods:A total of 60 patients with NPC were randomly divided into treatment group and control group. The treatment group took thalidomide and gargled with mixture of saline+gentamycin+dexamethasone when ra-diotherapy started, and the control group gargled only with mixture of saline+gentamycin+dexamethasone. The time of occurrence and degree of RIOM in both groups were registered at the same time. Results:The incidence of RIOM in treatment group was lower than that in control group (P<0.05). For the incidence of 3 or 4 grade RIOM, the treatment group was also lower than the control group. No statistical difference in terms of objective response rate was found between the two groups (P>0.05). There was no statisti-cally significant difference between the treatment group and the control group in the oral average dose, V30, V35, V40, V45, V50, and V54 (P>0.05). There was no statistically significant difference between the treatment group and the control group in the use of nutri-tion agents, hormones and antibiotics (P>0.05). There was no statistical difference between the groups in the drowsiness, peripheral nerve toxicity, hematologic toxicity and gastrointestinal reaction (P>0.05). Conclusion:Thalidomide can reduce the incidence and se-verity of RIOM for radiotherapy of patients with NPC, which deserves clinic application.
