Since trastuzumab was listed and approved for breast cancer in 2002, China has entered a new epoch of targeted therapy. Over the past 20 years, anti-human epidermal growth factor receptor 2 (HER2) targeted therapy for breast cancer in China has experienced the era of single-target, tyrosine kinase inhibitors, double-target and anti-HER2 plus antibody-drug conjugate. Advancement in the anti-HER2 targeted therapy is continuously changing the treatment mode of patients with HER2 positive status and even HER2 low expression, significantly improved their prognosis. In the past 20 years, Chinese scholars have participated in international clinical researches, completed a series of registration studies of imported drugs, developed new drugs with proprietary intellectual property rights, enriched the evidence of clinical research on HER2-targeted therapy, and formed a treatment system with both international standards and Chinese characteristics. In particular, the formulation of the Chinese Society of Clinical Oncology Breast Cancer Guidelines and the Chinese expert consensus on anti-HER2 targeted treatment in breast cancer are the concentrated embodiments of Chinese wisdom.

OBJECTIVE:
To investigate the change trends of sperm quality with seasonal variations among the volunteers of sperm donors in Beijing area, as well as the relationship between two parameters.
METHODS:
Semen data from the volunteers of sperm donors in Human Sperm Bank of Peking University Third Hospital were collected using a retrospective study method. The subjects were divided into 4 seasonal groups based on the lunar solar terms and the time of sperm donation. The data were assessed to find whether there were differences in semen parameters among different seasonal groups, and to analyze the change trends and the influence of seasonal factors on semen parameters.
RESULTS:
A total of 21 174 semen parameter data were analyzed. Firstly, to analyze all data as a whole, in spring, summer, autumn and winter groups, sperm concentration was (106.04±59.67)×106/mL, (97.61±47.41)×106/mL, (100.18±47.17)×106/mL, (100.59±38.68)×106/mL, respectively, and the spring group was significantly higher than the other 3 seasonal groups (P < 0.001); proportion of progressive motility sperm (PR) was 56.49%±12.76%, 58.02%±13.65%, 58.05%±12.36%, and 57.66%±12.61%, respectively, spring group was lower than the other three seasonal groups, and summer group was better among the latter (P < 0.001). There was no difference in normal rate of sperm morphology among the four seasonal groups. The qualified rate of sperm donors in the winter group was higher than that in the other three seasons groups (P < 0.01), while the qualified rate in the summer group was lower than that in the other three seasons groups. In addition, the semen parameters of the volunteers during the screening period and the official sperm donation period were analyzed respectively, which revealed that sperm concentration of spring group was higher than that of summer and winter groups, and PR was lower than that of summer and autumn groups. On account of the semen parameters of official sperm donation period, multiple linear regression analysis found that season was the main factor affecting sperm concentration, the average sperm concentration in spring group was about 6×106/mL higher than in winter group, but PR was 2.9% lower in spring group compared with autumn group (all P < 0.05).
CONCLUSION
Season was the influencing factor of semen quality of sperm donors in Beijing area. We recommend spring and winter may be the preferred seasons for sperm donation.

Objective: To investigate the safety, feasibility and short-term efficacy of total laparoscopic loop ileostomy reversal in patients after resection of rectal cancer. Methods: The clinical data of 20 patients who underwent total laparoscopic loop ileoscopic loop ileostomy after radical resection of rectal cancer at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, or Beijing Chaoyang District Sanhuan Cancer Hospital from October 2019 to June 2020 were collected and retrospectively analyzed. Results: All patients had successfully underwent total laparoscopic ileostomy reversal without conversion to open surgery or discontinued operation. No perioperative related death cases were found. In the whole group, the median operation time was 97 (60-145) minutes and the median intraoperative blood loss was 20 (10-100) milliliters. The median Visual Analogue Scale (VAS) score was 1.9 (1-5) one day after the operation. Nobody needed to use additional analgesic drugs. The median time to grand activities was 25 (16-42) hours, the median time to flatus was 44 (19-51) hours, and the median hospitalization after operation was 6.9 (5-9) days. No patients underwent operation related complications such as operative incision infection, abdominal and pelvic infection, intestinal obstruction, anastomotic leakage, bleeding and so on. Conclusions: Total laparoscopic loop ileostomy reversal appears to be safe, feasible and with promising efficacy for selected patients.
