Nitrogen-containing bisphosphonates exert antitumor activity through induction of apoptosis or inhibition of proliferation, invasion and migration in tumor cells, inhibition of angiogenesis and promotion of immune surveillance. Animal models show that bisphosphonates delay visceral metastasis progression. Both ABCSG-12 and ZOFAST trial have demonstrated that Zoledronate reduced breast cancer recurrence risks. Bisphosphonates are synergistic with a variety of chemotherapeutics, and sequential dosing is more effective, which may be attributable to increased uptake of bisphosphonates by tumor cells after pretreatment with chemotherapeutics. Metronomic administration of bisphophonates after chemotherapy provides bisphosphonates the promising antineoplatic potential.

A total of 21 papers about topical use of triamcinolone in the treatment of oral diseases were retrieved.1 7 of the 21 papers were about the treatment of oral lichen planus,3 were about recurrent aphthous ulcer and 1 was about Behcet's Syndrome.Topical use of triamcin-olone,either used alone or combined with other drugs,was effective in the treatment of oral lichen planus,recurrent aphthous ulcer and Beh-cet's Syndrome.No adverse drug reaction happened when triamcinolone was used in the patients after a short time application,while it hap-pened in the patients after prolonged-use.It may be also effective in the treatment of other allergy or immune dysfunction related oral mucosal diseases,of which more research should be carried out.

OBJECTIVE:To provide reference for the construction of suitable evaluation index system for the implementation of National Essential Medicine System in community health service center.METHODS:The frame of evaluation index system was designed by theoretical analysis,literature study and expert interviews methods.Delphi method was used to establish evaluation index system for National Essential Medicine System in Shanghai community health service center.Analytic hierarchy process was adopted to determine the weights of indicators at all levels.RESULTS:The positive coefficients of the two rounds consultations were 88.24％ (15/17) and 86.67％ (13/15).The authority coefficient of structural index,processing index and result index in the first round consultation were 0.68,0.68 and 0.69,respectively,which showed that the authority degree was higher.The coefficient of concordance in the second round consultation was higher than the first round (the indexes of structure,process and result in two rounds consultation were 0.286,0.306,0.193 and 0.345,0.358,0.337,respectively),which indicated the expert opinions were highly consistent.Established evaluation index system consisted of 3 fiust-level indexes,13 second-level indexes and 27 third-level indexes.CONCLUSIONS:The selected experts were representative,the consultation results were reliable,established evaluation index system was rational and the setting of weights was scientific.Also this study was a methodological exploration.

Objective To analyse the effect of eszopiclone combined with sertraline on serum S100βand clinical efficacy in patients with depression after cerebral infarction.Methods 58 patients who were diagnosed with depression after cerebral infarction were collected.All patients were randomly divided into experimental group and control group,29 cases in each group.Patients in the control group received sertraline treatment, patients in the experimental group were given eszopiclone treatment on the basis of control group, after the treatment, the serum levels of S100β,BDNF and clinical efficacy were detected in all patients.Results After treatment, compared with control group, the serum level of S100βwas lower in the experimental group(P<0.05); the serum level of BDNF was higher in the experimental group(P<0.05); the total efficiency was higher in the experimental group (P<0.05).Conclusion The eszopiclone combined with sertraline can significantly reduce the serum level of S100β,and improve serum level of BDNF in patients with depression after cerebral infarction,improve the therapeutic effect.

OBJECTIVE:To study the preventive effects of arhinhor-11 on acute alcoholism in mice. METHODS:48 mice were randomly divided into model group (sodium carboxymethyl cellulose),arhinhor-11 low-dose,medium-dose and high-dose groups [1.23,2.46,4.92 g(crude drug)/kg],with 12 mice in each group. Each group was given relevant medicine intragastrically, and 30 min later given 56% liquor intragastrically to induce acute alcoholism model. The disappearance time and recovery time of righting reflex were determined. 160 mice were grouped,given medicine and modeled with the same method,with 40 mice in each group. The alcohol concentration and alcohol dehydrogenase(ADH)activity in liver of 10 mice were determined 0.5,1,2,3 h af-ter giving alcohol. Other 10 mice were included in normal control (ig administration of sodium carboxymethyl cellulose). RE-SULTS:Compared with model group,the disappearance time of righting reflex were prolonged while recovery time shortened in arhinhor-11 groups,and alcohol concentration and ADH activity increased 0.5,1,2,3 h after giving alcohol (P<0.05 or P<0.01),especially 1 h after giving alcohol. 3 h after giving alcohol,alcohol concentration in blood of arhinhor-11 high-dose group decreased while ADH activity increased (P<0.05);there was no statistical significance among other arhinhor-11 groups (P>0.05). CONCLUSIONS:Arhinhor-11 has preventive effect on acute alcoholism in mice. It has a positive control effects on the alco-hol concentration in blood and ADH activity in liver.

Objective To study the clinical characteristics of intrauterine re-adhesions treated by transcervical resection of adhesion (TCRA). Methods Between January 2012 and January 2015, 12 patients with intrauterine re-adhesions after TCRA in other hospitals had fertility requirements , including 10 cases of severe intrauterine adhesions and 2 cases of moderate intrauterine adhesions .In our hospital , the 12 patients underwent laparoscopic exploration and TCRA .After operation the patients were treated with artificial cycle therapy for 3 months and then underwent hysteroscopic examination . Results In the operation, the remaining of 50%endometrium was found in 1 case, the remaining of 30%endometrium was found in 1 case, and the remaining of 20%endometrium in 9 cases.Only petechial and patchy residual endometrial islands were found in 1 case.Uterine dysplasia was found in 3 cases.Re-examinations of hysteroscopy 3 months after surgery showed 4 cases of uterine cavity normal recovery , 6 cases of moderate intrauterine adhesions, and 2 cases of mild intrauterine adhesions .Follow-up for 18-42 months (mean, 28.5 months) in the 12 cases showed 2 cases of term pregnancy and 1 case of spontaneous abortion .The other 9 patients had no pregnancy , 3 of which withdrew the treatment and 6 of which underwent further treatment . Conclusions Patients with intrauterine re-adhesions usually have seriously damaged endometrium and poor recovery .We suggest that TCRA should be completed by experienced professionals to reduce the residual endometrial destruction , so as to improve the treatment outcomes of intrauterine adhesions .

The recent literatures showed that the acupuncture therapy had played a special role in treating ischemic stroke, including the changes of fibrinolysis, amino acid neurotransmitters, active peptides, proteins in the blood, calmodulin, nitric oxide and the synthase, and so on. But the standard of judgments, the manipulations of acupuncture, the selection of acupoints, and the course of treatment remain uncertain.

The expression of matrix metalloproteinase-9 (MMP-9) after cerebral ischemia reperfusion injury can accelerate the damage of brain-blood barrier and plays an important role in brain edema after cerebral hemorrhage. The level of MMP-9 can reflex the severity of brain ischemia, indicate to the volume of infarct area and point out the prognosis of the disease. This article reviewed its source and expression,the gene regulation and polymorphism, hemorrhage transformation and nhibitors, and the mechanism was also analyzed.
