OBJECTIVE:To observe the effect of trantuzumab combined with preoperative adjuvant chemotherapy in the treat-ment of human epidermal growth factor receptors 2 (Her-2) positive breast cancer,and to investigate its clinical value. METH-ODS:80 patients with Her-2 positive breast cancer were selected and randomly divided into observation group and control group, with 40 cases in each group. The control group received routine preoperative adjuvant chemotherapy+modified radical mastectomy for Her-2 positive breast cancer;observation group was additionally treated with trastuzumab intravenously before operation,initial dose of 4 mg/kg,followed by 2 mg/kg,once a week,for consecutive 3 weeks,on the basis of control group. The effects of two regimen on the expression of HER-2,CD-34,MGA,E-cadherin and GCDFE-15 in Her 2 positive breast cancer focus were com-pared between 2 groups. ADR and follow-up survey were recorded. RESULTS:Compared with before chemotherapy,the expres-sion of HER-2(+)in observation group increased significantly,while that of HER-2(+ + +)decreased significantly;MGA posi-tive rate and GCDFP-15 positive rate decreased significantly while E-cadherin positive rate increased significantly;MDV of CD34 expression decreased significantly,with statistical significance(P<0.05 or P<0.01). Relapse rate and distance transport rate of ob-servation group were significantly lower than those of control group,with statistical significance(P<0.05). There was no statisti-cal significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Trastuzumab combined with preoperative adjuvant chemotherapy have good clinical efficacy and safety,and it can effectively reduce related indicator of Her-2 positive breast cancer focus. So it has positive significance in reducing recurrence and metastasis of breast cancer.

Objective:To investigate the expression of chemokine receptor in eupotic and ectopic endometrial tissues of women with endometriosis, and in endometrium of women without endometriosis.Methods:Normal endometrium, eutopic endometrium and endometriotic tissues were obtained from patients with endometriosis at laparoscopy. Total RNA was then extracted using the TRIzol reagent. The expression of chemokine receptors in these tissues were analyzed by way of semi-quantitative reverse transcriptase-polymerase chain reaction.Results:Compared to normal endometrium, the eutopic endometrium expressed significantly more CCR6, CCR8, CCR9 and CX3CR1(P

Objective To observe the clinical effect of the Bushen-Qiangjin capsule and calcium D in the treatment of aromatase inhibitors-associated bone loss (AIBL) in breast cancer patients. Methods A total of 65 patients were randomized into a treatment group and a control group, 32 in the control group taking calcium D, and 33 in the treatment group taking calcium D and Bushen-Qiangjin capsule. After a 3-month treatment, the bone mineral density T (BMD), bone-specific alkaline phosphatase (BALP), bone gla protein (BGP) and tartrate resistant acid phosphatase (TrACP) of two groups were evaluated. Results The BMD increased significantly after treatment in both groups (P<0.05), and the therapeutic efficacy of the treatment group was better than of the control group (P<0.05). After treatment, the level of BALP (308.76 ± 10.99 U/L vs. 280.00 ± 7.44 U/L, t=8.170) and the BGP (42.21 ± 3.04 ng/ml vs. 34.38 ± 2.06 ng/ml, t=6.818) of the treatment group were significantly higher than those of the control group (P<0.01). The level of TrACP decreased significantly after treatment in both groups (P<0.05), and the TrACP (60.12 ± 4.58 U/L vs. 67.25±4.06 U/L, t=1.653) of treatment group was significantly lower than that of the control group (P<0.05). Conclusions The Bushen-Qiangjin capsule can produce a content efficacy in treating AIBL in breast cancer patients, improving the BMD and bone metabolism.

Integrins are transmembrane receptors that have been implicated in the biology of various human physiological and pathological processes. These molecules facilitate cell-extracellular matrix and cell-cell interactions, and they have been implicated in fibrosis, inflammation, thrombosis, and tumor metastasis. The role of integrins in tumor progression makes them promising targets for cancer treatment, and certain integrin antagonists, such as antibodies and synthetic peptides, have been effectively utilized in the clinic for cancer therapy. Here, we discuss the evidence and knowledge on the contribution of integrins to cancer biology. Furthermore, we summarize the clinical attempts targeting this family in anti-cancer therapy development.

OBJECTIVE: To investigate the efficacy and safety of the bladder training in male patients before urinary catheter removal after mid-low rectal cancer surgery. METHODS: This was a prospective, open, randomized controlled study. INCLUSION CRITERIA: male patients; pathologically diagnosed as mid-low rectal adenocarcinoma; distance from tumor lower edge to anal margin ≤10 cm; standard radical surgery for rectal cancer, including intestinal resection and regional lymph node dissection. EXCLUSION CRITERIA: previous history of benign prostatic hyperplasia or history of prostate surgery; bladder dysfunction such as dysuria and urinary retention before surgery; local resection of rectal tumor or extended resection. According to the above criteria, 92 patients who underwent colorectal surgery at the Union Hospital of Fujian Medical University from June to December 2016 were prospectively included. The patients were randomly divided into bladder training group (n=43) and bladder non-training group (n=49) according to the random number table method. The study was approved by the Ethics Committee of the Union Hospital of Fujian Medical University (ethical approval number: 2016KY005) and registered with the China Clinical Trial Registration Center (ChiCTR) (registration No.ChiCTR-IOR-16007995). The implementation of patient's treatment measures, the data collection and analysis were based on the three-blind principle, using envelopes for distribution concealment. In the bladder training group, bladder training was routinely performed from the first day after operation to catheter removal, and in bladder non-training group the catheter was kept open till its removal. The catheter was removed in the early morning at the 5th day after surgery, and the spontaneous urine output was recorded and the residual urine volume of the bladder was measured after the first urination. The international prostate symptom score (IPSS) was applied to evaluate the patient's urinary function before and after surgery. RESULTS: The age of whole group was (58.6±10.9) years old, the body mass index was (22.4±2.7) kg/m , and the distance from tumor lower edge to anal margin was (6.5±1.9) cm. The baseline data, such as age, body mass index, distance from tumor lower edge to anal margin, preoperative IPSS score, preoperative bladder residual urine volume, neoadjuvant radiotherapy and chemotherapy, preventive ileostomy and surgical procedure were not significantly different between two groups (all P>0.05). There was no significant difference in IPSS scores evaluated at the second day (3.6±4.0 vs. 3.5±3.4, t=0.128, P=0.899) and one month (3.7±2.9 vs. 3.0±3.1, t=1.113, P=0.269) after catheter removal between the bladder training group and bladder non-training group. No significant difference in the postoperative residual urine volume of bladder (media 44 ml vs. 24 ml, Z=-1.466, P=0.143), the first spontaneous urination volume (median 200 ml vs. 150 ml, Z=-1.228, P=0.219) after catheter removal, and postoperative hospital stay [(8.2±4.5) days vs. (9.1±5.5) days, t=-0.805, P=0.423] was found. Urinary infection rate was 20.9%(9/43) in the training group, which was even higher than 8.2%(4/49) in the non-training group, but the difference was not significant(χ²=3.077, P=0.079). No patient needed re-catheterization in either group. CONCLUSIONS The routine bladder training after mid-low rectal cancer surgery does not improve the urinary function, and can not reduce the residual urine volume of bladder after catheter removal. This routine clinical practice is not helpful for the bladder function recovery after rectal cancer surgery.
