Objective To observe the therapeutic effect of clarithromycin combined with Cassia Twig-Poria Cocos capsule on patients with chronic pelvic inflammatory disease and its influence on high sensitivity C - reactive protein (hs-CRP). Methods 106 cases of patients with chronic pelvic inflammatory disease were selected to be divided into the observation group and control group with each group of 53 patients. The patients in control group were only given clarithromycin, on the base of control group, patients in observation group were given Cassia Twig-Poria Cocos. Both group were treated for three courses of 7-14 days. Then the therapeutic effect, adverse reactions, hs-CRP, erythrocyte sedimentation rate and hematocrit of patients were investigated. Results The total effective rate of patients in observation group was 90.57%, and the control group was 75.47%. The total effective rate of observation group was higher than control group with statistically significant difference (P<0.05). The hs-CRP, erythrocyte sedimentation rate and hematocrit of two groups both decreased after treatment (P<0.05) and these indexes of observation group was much less than control group (P<0.05). Besides, there was no difference of incidence of adverse reactions between two groups during the treatment. Conclusion Treatment of clarithromycin combined with Cassia Twig-Poria Cocos capsule on patients with chronic pelvic inflammatory disease not only can lessen inflammatory reaction, but also can improve the therapeutic effect effectively.

ObjectiveTo observe the efficacy of maintenance hormonal treatment after response to chemotherapy in advanced breast cancer. Methods8 patients with advanced breast cancer were treated with chemotherapy,maintenance hormonal therapy were given after response to chemotherapy.The efficacy was evaluated every 2 cycles of chemotherapy and 2 months of endocrine therapy according to RECIST standard.Results8 patients received chemotherapy for 2-8 cycles (median 4 cycles). All patients got PR, the duration of chemotherapy was 1-6 months (median 2 months), the time to failure of chemotherapy was 4 months. Until the last follow-up day (31th December 2010), the time to progression was 6-86 months (median 13.5 months).Survival was 6-86 months(median 21.5 months).Seven patients quit the chemotherapy due to severe side effects of hematologic toxicity,fatigue or nausea vomiting.One patient died because of allergy to paclitaxol.Conclusion Maintenance hormonal treatment after patients with metastatic breast cancer response to chemotherapy may prolong the duration of effective therapy and improve the QOL.

Objective To conduct a retrospective study about drug-induced hyperthermia (DIH) based on DIH data obtained in medical practice,and elucidate the relationship between DIH incidence and antibacterials overuse.Methods To investigate successively the medical records of inpatients from orthopaedics department in Fudan university affiliated Jinshan hospital at two different periods,and data of DIH cases were extracted to perform a comparative study.The period for 229 effective cases of group Ⅰ was from Feb.1 to Apr.30,2011,before significant improvement on antibacterials use.The period for 342 effective cases of group Ⅱ was from Jul.1 to Sep.30,2012,after the effective enforcements of regulation on antibacterials use.Inclusion criteria for DIH were:①an oral temperature ≥37.6 ℃ since postoperative day 4,②no evidence of infection,③a time relationship between fever and the administration of causative drugs:a fever occurring with drug administration and disappearing after drug cessation within 3 days,④no other causes for the fever,⑤oral temperature ≤ 37.6 ℃ until leaving hospital.Exclusion criteria for DIH were listed below:①possible pathological fever,e.g.,in cancer,②hospitalization within 3 days,③no surgery,④severe trauma,for example,visceral or central nervous system injury.Results All causative drugs were for injection.By comparison,duration of antibacterial administration is significantly shorter in group Ⅱ than in group Ⅰ (1.7 ± 1.7 vs.4.6-± 1.8days,P ＜ 0.01),and total DIH incidence and antibacterials related DIH incidence were significantly lower in group Ⅱ than in group Ⅰ (7.3％ vs.30.1％,1.5％ vs.25.3％,both P ＜0.01).Conclusion DIH incidence is related with drug type especially with antibacterials overuse,and changed with drug program.DIH was more serious for injection of antibacterials than injection of traditional Chinese medicine.Decrease of antibacterials usage is positively associated with the decreased DIH incidence.Safe medication should begin from safe usage of antibacterials.

Objective To investigate the effects of 20 Hz repetitive transcranial magnetic stimulation (rTMS) with different intensities on neurobehavior and expression of glial fibrillary acidic protein (GFAP) in ischemic penumbra of rats with cerebral infarction,so as to explore the probable mechanism. Methods Forty-three rats were randomly divided into a blank control group( n =7 ),a model control group( n =7),a sham stimulation control group(n =8) and a rTMS group (n =21) ; the rTMS group was further subdivided into 3 subgroups:80％ MT subgroup,100％ MT subgroup and 120％ MT subgroup,with 7 rats in each subgroup.The cerebral infarction model was established by right middle cerebral artery occlusion (MCAO) in each group except the blank control group.The 3 rTMS subgroups were given 14 successive blocks of 20 Hz rTMS with corresponding intensity.The sham stimulation control group received sham treatment (without any output).The model control group was given no stimulation,and the blank control group did not receive any special treatment.Functional assessments were performed at 3 different time points.After 14-day treatment,the expression of GFAP proteins in ischemic penumbra were detected by immunohistochemistry technique. Results Functional outcome reflected from 3 behavioral tests in 100％ MT subgroup after 14-day stimulation was better than 1 day after operation,while in the other rTMS subgroups functional outcomes were just better in 2 behavioral tests.The expressions of GFAP in 3 rTMS subgroups were all less than that in model control group. Conclusions The 20 Hz rTMS with 80％ MT and 100％ MT might be safe and effective to improve the functional outcome in rats with acute cerebral infarction,especially 100％ MT.Decrease of expression of GFAP in ischemic penumbra might be one of the mechanisms of beneficial effects of rTMS in ischemia brain injury.

Objective To compare and evaluate the clinical efficacy and side effect of vinorelbine plus gemcitabine and vinorelbine plus cisplatin combinations in advanced non-small-cell lung cancer(NSCLC). Methods 56 cases with non-treated advanced NSCLC were unrandomly divided into two groups: the GN group (27patients) treated with vinorelbine plus gemcitabine, the NP group (29 patients) treated with vinorelbine plus cisplatin,1/3 weeks×2～6 cycles. Results For the GN group, the overall response rate was 37.7 %, MTTP was 5.1months,one year survival rate (1-ySR) was 40.7 %. There were no significant difference in the response rates and the survival rates for the GN group compared with the NP group (P ＞0.05); But on the side effect of toxicities, WHO grade anemia and nausea/vomiting and tiredness of the GN group was significantly milder than the NP group (P ＜ 0.05). Conclusion Vinorelbine combined Gemcitabine regimen (GN) is active and well-tolerated. It is worth to investigate GN recommended as the first line chemotherapeutic regimen for the treatment of patients with advanced NSCLC.

Objective To investigate the effects of high-frequency repetitive transcranial magnetic stimulation (rTMS) at different intensities on the ultrastructure of an ischemic brain penumbra and the expression of brainderived neurotrophic factor (BDNF) using rats with permanent middle cerebral artery occlusion (MCAO).Methods Forty-two rats were randomly divided into a blank control group,an MCAO model control group,a sham stimulation control group and an rTMS group.The rTMS group was divided further into 3 subgroups:an 80％ of motor threshold (MT) subgroup,a 100％ of MT subgroup and a 120％ of MT subgroup.The cerebral infarction model was established by right MCAO.rTMS treatment was given 24 hours after the MCAO model was successfully established.The rTMS group and sham stimulation control group were given 20 Hz rTMS with the planned intensities.The MCAO model control group was not given any stimulation.After 14 days of treatment,transmission electron microscopy,immunohistochemical and Western blotting ( WB ) methods were used to investigate the ultrastructure of the ischemic penumbra and the expression of BDNF.Results Damage reflected in the ultrastructure in the 3 rTMS subgroups was less than in the model control group and the sham stimulation control group.Expression of BDNF protein increased significantly in 100％ of the MT group and blank control group rats as compared with that in the sham stimulation control group,while the blank control group and the 3 rTMS subgroups had no statistically significant difference in comparison with the MCAO model control group.The expression of BDNF protein had no statistically significant difference between any of the groups.Conclusion 20 Hz rTMS might,especially at 100％ of the MT,promote the recovery of the ultrastructure of neural tissues in the ischemic penumbra after acute cerebral infarction and enhance the expression of BDNF in the ipsilesional hemisphere.This may be one of the important mechanisms of rTMS's effectiveness in the treatment of ischemic stroke.

Objective:This study aims to evaluate the clinical effect and adverse reactions of oxaliplatin or irinotecan plus capecitabine treatment for colorectal liver metastases. Methods:Data from 125 cases of colorectal liver metastasis patients were continuously enrolled and randomized into two groups, i.e., 63 in group one (treatment group) and the other 62 in group two (the control group). Capecitabine was administered at 1 000 mg/m2 doses, twice a day from d1 to d14, to all patients. Irinotecan was administered at 150 mg/m2 in d1 to group one, and oxaliplatin was administered at 130 mg/m2 in d1 to group two. The drug administration cycle lasted for 21 days in both regimens, with at least 6 administration cycles. The total course was for 6 months at most. The therapeutic efficacy, median progression-free survival time, median survival time, short-term clinical effect, and adverse drug reaction were monthly determined. Results:The overall response rates and disease control rates were 33.3%and 66.7%in group one, respectively, and 35.5%and 70.9%in group two, respectively, with no significant differences between the groups (P>0.05). The median survival time and median progression-free survival time were 14 months and 5 months in group one, respectively, and 12 months and 5 months in group two, with no significant differences between the two groups (P>0.05). The level-Ⅲand-Ⅳadverse drug reactions mainly include hematological toxicity, gastrointestinal reactions, and hand-foot syndrome. The diarrhea frequency is obviously higher in group one than in group two, and the difference between the two groups is sta-tistically significant (P<0.05). No significant differences were observed in the other adverse reactions between the groups (P>0.05). Conclusion:The Oxaliplatin or Irinotecan plus Capecitabine treatment is effective for colorectal liver metastases, which enhances survival rate and reduces patient suffering because of it has less side effects and good tolerance. The treatment must be further generalized and clinically applied.
