Trastuzumab is a specific inhibitor against human epidermal growth factor receptor-2 (HER-2). Trastuzumab is widely used in the neo-adjuvant treatment of HER-2 breast cancer. Large-scale randomized and controlled clinical trials have demonstrated that pathologic complete response rates (pCRs) were significantly increased with neo-adjuvant trastuzumab therapy plus chemotherapy than with regular chemotherapy. The use of trastuzumab plus chemotherapy with lapatinib supplements could further improve pCR rates. An-thracycline and non-anthracycline drugs could both be used concurrently with trastuzumab. Endocrine therapy could be used as an alter-native for estrogen receptor-positive patients. pCR is a powerful predictor of long-term outcomes in HER-2 positive patients under neo-adjuvant therapy with trastuzumab. However, patient loss of HER-2 expression with residual disease after neo-adjuvant therapy with trastuzumab is a poor prognostic factor. This study paper will provide a review of related research.

Tyrosinase is a key enzyme related to skin pigmentation disorders of elderly people, while self-aggregation of the amyloid-beta peptide, Abeta42, has been considered as a key event in the pathogenesis of Alzheimer's disease (AD). The present study was undertaken to investigate the inhibitory effects of 20 samples from Rhodiola species on tyrosinase and Abeta42 aggregation, and to isolate their corresponding bioactive components. The results demonstrated that the oligomeric proanthocyanidins (OPCs) commonly found in Rhodiola species were the major bioactive components corresponding to their anti-tyrosinase and anti-Abeta42 aggregation bioactivities. Salidroside, a representative compound of Rhodiola plants, proved not to be active in the present studies.

Objective To investigate the status of safe injection practice in primary medical institutions.Methods 55 primary medical institutions in Hubei Province were randomly selected,questionnaire survey on status of safe injection in primary medical institutions was conducted.Results A total of 55 questionnaires were distributed,50(90.91％) valid questionnaires were obtained.All valid questionnaires were from primary level medical institutions of Hubei Province,16 of which were from community health centers,17 from township health centers,and 17 from village health clinics.None of 50 primary medical institutions repeatedly used syringe and hemostix,all used disposable sterile syringe,only 7(14.00％) medical institutions used retraction type self-destructing syringe.Only 5 (10.00％) medical institutions were equipped with hand hygiene facilities and sharps containers,32 (64.00％) medical institutions didn't provide sharps containers on treatment carts,21 (42.00 ％) injection rooms didn't install hand-drying facilities,18 (36.00 ％)medical institutions didn't provide alcohol-based hand rub on treatment carts and didn't install hand-drying facilities in treatment rooms.Of sharp injures among health care workers (HCWs) reported in 2015,114 HCWs sustained 117 times of injuries,74 cases(63.25 ％) were caused by ampoule.Of medical waste disposal,there existed some problems,such as leakage and repeated use of sharps box,didn't close sharps box timely,as well as without providing sharp containers in locations where sharps might be produced.Conclusion There are a variety of hidden risks of unsafe injection in primary medical institutions,like insufficient facilities and unsafe disposal of medical waste.

Hemophagocytic syndrome is a group of fatal immune function disorder,which can be divided into primary and secondary HPS.The disease is complex,lacking of specificity,difficult in diagnosis with quick progress,high mortality and poor prognosis.The diagnosis is mainly based on the HPS-2004 diagnostic criteria,etoposide,dexamethasone and cyclosporine would be first chosen for treatment.This article reviews the clinical advances on etiology,diagnosis,treatment and prognosis of hemophagocytic syndrome.

Objective To evaluate the diagnosis and treatment of primary breast lymphoma(PBL).Methods Clinical data of 49 PBL cases diagnosed in our center from 1997 to 2011 was retrospectively analyzed.Results 1 case was male,48 cases were female.Most patients were at the age of 35-55 years.Painless mass was the most common symptom which was most often seen on the upper-outer quadrant of the right breast,accounting for 61.11％ in this group.Preoperative misdiagnosis rate was high by mammography,B ultrasonic and hollow needle pathologic examination.Final diagnosis could only made by postoperative histopathologic examination.In this group 1 case was Hodgkin lymphoma and 48 cases were non-Hodgkin lymphoma(NHL) originating from B cells.46 patients underwent surgery and chemotherapy followed by radiotherapy in 16 cases.Median time of follow up was 40 months,5-year overall and disease free survival was 48％ and 28％ respectively,and bone marrow was the most common metastatic organ.Conclusions The prognosis of PBL is poor.The image diagnosis lacks specificity.Paraffin sections and immunohistochemistry were the main means to make a definite diagnosis.Chemotherapy-based comprehensive treatment is the strategy in the management of PBL instead of radical mastectomy.

Objective To explore the clinical effect of small incision extracapsular cataract extraction combined with implantation of artificial lens and phacoemulsification combined with implantation of artificial lens for patients with cataract.Methods One hundred and ten patients (142 eyes) with cataract were selected,55 patients (69 eyes) were treated with small incision extracapsular cataract extraction combined with implantation of artificial lens (observation group),and 55 patients (73 eyes) were treated with phacoemulsification combined with implantation of artificial lens (control group).After treatment,the corrected vision and quality of life were observed 1-week,1-and 3-month after operation,and the complications were recorded.Results The vision 0.6-1.0 of 1-week,1-and 3-month in observation group were 34 eyes (49.3％,34/69),61 eyes (88.4％,61/69) and 63 eyes (91.3％,63/69) respectively,in control group were 37 eyes (50.7％,37/73),64 eyes (87.7％,64/73) and 65 eyes (89.0％,65/73) respectively,there were no statistical differences (P ＞0.05).The quality of life score 1-week,1-and 3-month in observation group were (87.5 ± 10.7),(91.2 ± 5.3),(94.3 ± 5.8) scores respectively,in control group were (85.9 ± 11.5),(90.6 ± 6.7),(94.5 ± 6.0) scores respectively,there were nostatistical differences (P ＞ 0.05).The rate of complications in observation group was 23.2％ (16/69),in control group was 37.0％ (27/73),there was statistical difference (P ＜ 0.05).Conclusions The vision recovery and quality of life in cataract patients treated with small incision extracapsular cataract extraction combined with implantation of artificial lens are similar to treated with phacoemulsification combined with implantation of artificial lens.However,with fewer complications,small incision extracapsular cataract extraction combined with implantation of artificial lens is a more safe and reliable treatment method.

Adjuvant treatment, which includes chemotherapy and endocrine therapy, for early breast cancer may impair bone den-sity, resulting in bone loss. The third generation bisphosphonate-zoledronic is an anti-resorptive agent that inhibits osteoclast-mediated bone resorption. This drug can be mainly used in the treatment of hypercalcemia caused by bone metastases of the cancer. The Zome-ta-Femara Adjuvant Synergy Trial revealed that immediate zoledronic acid and endocrine therapy not only prevents bone loss, but also reduces recurrence. The Austrian Breast and Colorectal Cancer Study Group-12 (ABCSG-12) also confirmed that zoledronic acid, when combined with endocrine therapy, could reduce the risk of cancer disease progression and death. Moreover, preclinical studies and clini-cal trials have demonstrated the synergistic antitumor effects of chemotherapy and zoledronic acid. Neo-adjuvant zoledronic acid to re-duce recurrence trials showed that the addition of zoledronic acid to adjuvant chemotherapy significantly reduced the risk of disease pro-gression and death in postmenopausal women more than five years postmenopause at the beginning of the study or over 60 years of age at the baseline. The ABCSG-12 subgroup analysis based on age (≤40 years or>40 years) also showed that zoledronic acid can signifi-cantly improve the prognosis in women who were over 40 years at the study entry. These results suggest that zoledronic acid administra-tion in patients with lowered estrogen levels (naturally or as a consequence of adjuvant treatment) easily exerts anti-tumor effects. How-ever, the optimal dose and duration of zoledronic acid requires further studies. More clinical trials should be performed to provide suffi-cient evidence to support the effectiveness of zoledronic acid in the treatment of early breast cancer.
