China Pharmacy 2016;27(29):4127-4129,4130
OBJECTIVE:To investigate clinical efficacy and safety of trastuzumab combined with neoadjuvant chemotherapy on breast cancer,and discuss its effects on the expression of HER2 protein,B7 homolog 1(B7-H1)and IL-2. METHODS:62 patients with breast cancer confirmed by pathological biopsy,whose test results of immunohistochemistry combined with fluorescence in situ hybridization(FISH)was overexpression of HER2,were selected as the research object. They were randomly divided into observa-tion group and control group with 31 cases in each group. Control group was given carboplatin combined with docetaxel neoadjuvant chemotherapy before surgery. Observation group was additionally given Trastuzumab for injection intravenously 4 mg/kg in the first week,2 mg/kg in second-eighteenth week,once a week,for consecutive 18 weeks. Modified radical mastectomy was conducted 2 weeks after chemotherapy. Clinical efficacy and the occurrence of ADR were observed in 2 groups. The expression of HER2 protein, B7-H1 and IL-2 in tumor tissues were compared between 2 groups before and after treatment. With 1-year follow-up,tumor recur-rence rates,metastasis rates and survival rates were recorded in 2 groups. RESULTS:After treatment,total effective rate of observa-tion group was 83.87%,which was significantly higher than that of control group (58.06%),with statistical significance (P<0.05);the test result of HER2 protein in lesion tissues was non-overexpression in 19 cases (61.29%) in observation group which was significantly higher than that of control group(11 cases,35.48%),with statistical significance(P<0.05);the positive expres-sion rates of B7-H1 and IL-2 in lesion tissues of observation group were significantly lower than those before treatment and control group after treatment,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). During 1-year follow-up period,except that there was no statistically significant difference in survival rate be-tween 2 groups(P>0.05),the recurrence rate and metastasis rate of observation group were significantly lower than those of control group,with statistical significance(P<0.05). CONCLUSIONS:The application of trastuzumab combined with neoadjuvant chemo-therapy before breast cancer modified radical mastectomy can effectively improve the expression levels of HER2 protein,B7-H1 and IL-2 in lesion tissue of patients with breast cancer,promote clinical efficacy with good safety and low risk of tumor recurrence and metastasis after operation.

Journal of Jilin University(Medicine Edition) 2000;26(6):656-658
Objective:To study histocompatibility of self-made stents made of NiTi alloy in rabbits.Methods: To place 30 stents made of NiTi alloy into 30 rabbits trachea through mouth under general anethesia,to observe local tissue reaction from 1 week to 6 months and to try to find pathological changes of main organs of rabbits in the 6 th month. Results:During observation,apart from dyspnea in two rabbits,one died at 3 day and the other died at 6 week after implantation. Autopsy showed the implanta.tion sites were occluded by granulation tissue. All other rabbits were normal and implantation sites were patent. In the first three weeks we could observe acute inflammation at the implantation sites while after 5 weeks we could observe chronic inflammation there. We observed that the structure of epithelial cells tended to be normal by telemicroscope. There are no pathological changes in liver, spleen, kidney, lung, heart and brain tissue. Conclusion:Self-expanding stents possess good histocompatibility and have no toxic reaction to whole body and fit to implantation into human body.

Objective To investigate main causes leading to conversions to open surgery during laparoscopic cholecystectomy (LC) in the treatment of acute cholecystitis. Methods A total of 32 cases of acute cholecystitis received LC were analyzed. Results Out of the 32 cases of acute cholecystitis, LC was successfully accomplished in 25 cases (78.1%) and a conversion to open surgery was required in 7 cases (21.9%). Major causes of the conversion included the necrosis of the gallbladder(4 cases) and the failure to expose the Calot’s triangle(3 cases). Conclusions Conversions to open surgery should be made during LC when a gangrenous cholecystitis is confirmed or the Calot’s triangle cannot be well exposed.

0.05).The results of Western blotting and immunohistochemical method showed that HO-1 protein expression increased in DOX group and DOX-IR group,and was negative in normal group.More distruction of ultrastructural changes of hepatic cells in IR group was found than in DOX-IR group by transmission electron microscope.Conclusion Doxorubicin pretreatment could protect the liver from ischemia-reperfusion injury,which may be related to HO-1 expression induced by doxorubicin,low dosage of doxorubicin does little harm to rat liver.

Objective To investigate the degradation characteristics of the large-scale brain functional networks during aging by functional magnetic resonance imaging measurement and explore its intrinsic mechanism.Methods 40 healthy subjects including 20 elderly persons [mean aged(72.4 ±4.6)years] and 18 young persons [mean aged(23.9± 1.8) years] were enrolled in this study.All subjects underwent functional MRI scanning at blood oxygenation level-dependent contrast resting state.Four canonical resting-state networks,including the default mode network (DMN),dorsal attention network (DAN),executive control network (ECN),salience network,and visual network,were extracted by the seed zone and double regression methods.The functional connectivities in these canonical networks were compared between the young and elderly persons.Results Compared with young persons,the elderly showed the distinct and disruptive alterations in the large-scale aging-related resting brain networks.The impairment of ECN was the most serious,followed by the impairment of DAN.The salience networks and DMN showed relatively limited functional connectivity disruption.The networks associated to higher-order brain functions were impaired,while the visual network,which served as a network related to low-order brain functions,had no significant change.Conclusions The aged brain in healthy subjects is characterized by organized change in networks,and the selective impairments of large-scale brain networks were more significant in the networks associated to higher-order brain functions as compared with the networks related to low-order brain functions.

Objective To investigate the clinical characteristics of young rectal carcinomain in order to improve the diagnostic level and therapeutic efficacy at the early stage.Methods Clinical data,including clinical manifestations,misdiagnosis,clinical pathology and prognosis which from 47 cases of young rectal carcinoma were analyzed retrospectively and compared with those from 99 cases of old rectal carcinoma.Results The average course of disease was 6.98 months in young patient group,it was shorter than that in old patient group(9.16 months).The misdiagnosis rate of young group(61.70%) was significantly higher than that in old group(28.28%)(P 0.05).Conclusion Compared with the old patients,advanced stage and poorly differentiated carcinoma are more common in young patients with rectal carcinoma.But the 5-year survival rates of the young and old patients are similar.In addition,T stage and lymph node metastasis are the independent prognostic factors.Therefore,early diagnosis and treatment are crucial to improve the survival rate in young patients with rectal carcinoma.
