Objective To study the clinical value of preserving intercostobrachial nerve(ICBN) during axillary lymph node dissection.Methods The clinical data of 146 cases of operated breast cancer of stage Ⅰ、Ⅱ、Ⅲa were analyzed.All cases were divided into twe groups randomly:preserved group(n=67) preserved ICBN in axillary lymph node dissection operation;control group(n=79) resected ICBN regulary in the operations.The number of lymph node dissection and the incidence of abnormal sense on the skin of inside upper arm were compared between groups.Results In one month,three months and six months followed up:the incidence of ahnormal sense on the skin of inside upper arm was 17.9%,11.9%,7.4% in preserved group,which was lower than that (74.9%,60.7%,59.5%) in control group significantly (P＜0.01).The diflrence between the two groups was significant.No local recurrence was occurred after opreations from eight months to five years examined.It was none difference that period of operation and the number of lymph node dissection between the groups.Conclusions Preserving ICBN in axillary lymph node dissection for breast cancer of stage Ⅰ、Ⅱ、Ⅲa could decrease the incidence of abnormal sence on the skin of inside upper arm.It eouldnt increase the incidence of local recurrence.It can improve the life quality of the patients after operations.

Objective To explore the clinical features of chronic myelogenous leukemia (CML) combined with solid malignant neoplasms. Methods The clinical data of 8 CML patients with solid malignant neoplasms who were admitted to the Affiliated Tumor Hospital of Zhengzhou University, the Central Hospital of Nanyang City, the First Affiliated Hospital of Science and Technology University of Henan, and the Central Hospital of Xinxiang City from August 2006 to August 2018 were analyzed retrospectively. The clinical features, treatment and prognosis of the patients were summarized with the review of literature. Results Among the 8 patients, 3 were male and 5 female, aged 40-76 years, with a median of 50 years old. Seven cases were in CML chronic phase, and 1 was in accelerated phase. Seven patients were treated with tyrosine kinase inhibitor (TKI), and only 1 patient was treated with hydroxyurea. In 8 patients, two cases presented with synchronous multiple primary cancer (SMPC), 6 cases presented with heterochrony multiple primary cancer (HMPC). two patients received the operation, 1 patient received the operation and chemotherapy, 4 patients received chemotherapy, and 1 patient received the isotope treatment. One SMPC patient died and another one was under treatment, and 6 HMPC patients were under treatment. ConclusionsThe relationship between CML and solid malignant neoplasm is under discussion, but patients with CML and solid malignant neoplasm are not unusual. Clinicians should raise awareness to avoid misdiagnosis. The treatment should follow the two main lines that are comprehensive treatment and individualized treatment.

Objective:To investigate the feasibility, effectiveness and safety of indocyanine green (ICG) navigation in the surgical resection of abdominal wall endometriosis (AWE).Methods:Seven women undergoing surgery for AWE in First Affiliated Hospital of Sun Yat-sen University (from July 1, 2021 to October 1, 2021) were collected. After exposure of the focus, ICG were used intravenously (0.25 mg/kg) as fluorescent dye for the intraoperative evaluation of AWE vascularization. Resection of the AWE was guided by direct visualization of the focus under standard laparoscopy with a near-infrared (NIR) camera head. Surgical margin around the AWE (3, 6, 9 and 12 point) and the margin under the focus were obtained for postoperative pathological examination of endometriosis. Time from injection to fluorescence visualization, the proportion of fluorescence visualization, time of fully resection of AWE, side effects related to the use of ICG, perioperative complications as well as the pathological result of the surgical margins were recorded.Results:ICG fluorescence of the AWE were seen in 5 patients (5/7). The mean time from injection to fluorescence visualization was (46.7±9.8) s. The mean time of fully resection of AWE was (16.4±7.0) minutes. There were no side effects related to the use of ICG. The rate of class-A wound healing was 7/7. All of the surgical margins were confirmed endometriosis-negative by postoperative pathological examination.Conclusion:ICG fluorescence visualization could conduct accurate resection of AWE, which is clinically safe and effective.

Objective: To investigate the change of hepatitis B surface antibody (HBsAb) titer and its long-term protection and infection rates between 1 and 3-year-old children whose mothers were chronic hepatitis B pregnant woman with HBeAg positive and high viral load after successful blocking of mother-to-child transmission. Methods: One-year-old children whose mothers were hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) positive, with HBV DNA≥10⁶IU/ml were enrolled, then were followed up till 3 years old, and tested the five serological markers of hepatitis B and biochemical parameters at the age of one and three years respectively, and analyzed HBsAb titer, positive rate, negative rate and infection rate of 1 to 3-year-old children without enhanced vaccination; meanwhile, data of HBsAb titers at the age of 7 months were collected HBsAb titer, positive rate, and negative rate were analyzed. Results: Totally 264 1-year-old children were enrolled into the study, including 178 children without enhanced vaccination between seven months and 1 year of age, and 114 children without enhanced vaccination between 1 year and 3 years of age. Our result showed that there were no infected children at the age between 1 and 3 years. HBsAb titer decreased from 7 months to 1 year old and dropped from 1 000 IU/L to 509.43 IU/L (P<0.05), and the antibody was still protective. From 1 year to 3 years old, HBsAb titer dropped from 466.72 IU/L to 67.3 IU/L (P< 0.05); at the age of 3 years, 60.52 % children were either weakly positive or negative, but still protective, but significantly less than those who had the reinforced vaccination. As a result , the children without the enhanced vaccination between 1 and 3 years of age were still at high risk. Conclusions If the antibody was protective at 7 months, children were not easily infected between 1 year and 3 years of age. At the age of 3, the antibody dropped to low or no responsive levels, and the children were still at high risk. It is necessary to take protective measures and supplement the vaccine.
