Ten years had passed for the molecular targeted therapy since approval by the U.S.Food and Drug Administration of the first monoclonal antibody-Rituximab,for the treatment of the B-cell non-Hodgkin's lymphomas with positive CD20- The targeting therapy,which may be a promising approach in the future,has significantly improved the patients'qualities of lives and prognosis because it has higher selectivity and less adverse effects than current chemotherapy and radiotherapy.In the past decade,with the fast development of novel targeting drugs and extension of therapeutic fields,the limitations associated with the targeted treatments were received attentions.

B-cell lymphoma is a heterogeneous group of disorders involving malignant proliferation of B lymphocytes, accounting for approximately 85%of non-Hodgkin lymphoma. Combined use of rituximab and chemotherapy remarkably improves the survival of pa-tients with B-cell lymphoma. Despite the increase in treatment response, some patients suffer relapsed or refractory lymphoma. Nu-merous novel treatment options have been developed in pre-clinical and clinical practice, including targeted therapies, auto-hemato-poietic stem cell transplantation, cellular immunotherapy, and radioimmunotherapy. This review describes recent advances in B-cell lymphoma treatment and discusses future perspectives.

Objective To summarize the value of laparoscopic operation using an ultrasonic scalpel for the radical treatment of Hischsprung’s disease (HD) in infants and children. Methods Laparoscopic operation was performed in 20 infants and children with HD under general anesthesia from February 2003 to January 2006. The CO_2 pressure of pneumoperitoneum was set at 10~12 mm Hg. By way of three abdominal ports, the diseased colon and rectum were mobilized by dissecting the supplying vessels and severing the peritoneal reflection in the pelvic floor. The modified Soave pull-through procedure was employed to incise and mobilize the rectal mucosa at 0.5 cm above the dentate line. The lateral ligament of rectum was severed and the intraabdominal cavity was reached through the peritoneal reflection. The diseased colon was pulled through the anus passing the level of the transition zone for resection. Then coloanal anastomosis was made between the proximal colon and the cutting edge of the anal canal above the dentate line. Results All the procedures were completed smoothly. The operation time was 120~210 min (mean, 132 min). The length of resected colon was 20~55 cm (mean, 35 cm). The intraoperative blood loss was 5~20 ml (mean, 14 ml), with no need of blood transfusion. Enterocolitis happened in 2 cases postoperatively. Follow-up observations in the 20 cases for 3~36 months (mean, 12.5 months) found no complications. The patients had 1~2 times of fecal discharge per day during follow-up. Conclusions Laparoscopic pull-through procedure using an ultrasonic surgical scalpel has advantages of minimal invasion, little hemorrhage, simple performance, quick recovery, and low complication rate.

Objective To investigate the feasibility of two-port laparoscopy-assisted resection of the Meckel’s diverticulum in children. Methods Resection of the Meckel’s diverticulum was performed under a laparoscope in 13 children in our hospital from July 2002 to March 2006. Two 5-mm trocars were introduced at the infraumbilical ring and the right lower abdomen, respectively. When the Meckel’s diverticulum was found, the incision was prolonged to 2 cm long along the inferior border of the umbilicus, the diverticulum was removed externally and the intestine was anastomosed. Results The operation was completed successfully without conversion to open surgery. The mean operation time was 50 min (range, 40-70). The intestinal function of the patients recovered 24 hours after the operation, and then liquid food was given at 3 days postoperatively, and the patients was discharged from hospital within 5-7 days after the operation. The patients were followed up for 6-48 months (mean, 13), during which no one had recurrence, intestinal adhesion, or intestinal obstruction. Conclusions Two-port laparoscopy-assisted resection of Meckel’s diverticulum is safe and feasible for children. The recovery time and hospital stay are short after the procedure.

Objective To summarize the experience of l ap aroscopic pyloromyotomy for the treatment of infantile hypertrophic pyloric sten osis (IHPS). Methods Laparoscopic pyloromyotomy was employed i n 50 cases of IHPS from April 2001 to April 2004. The patients aged 12~90 days ( mean, 35 days). Three 3-mm-diameter trocars were introduced into the abdominal c avity via the left, right and upper abdominal wall, respectively. A non-traumati c grasping forceps was inserted through the left trocar to manipulate the gastri c wall near the pylorus. Through the right trocar, a retractable pyloromyotomy s calpel, a stripper and a dissecting forceps were in turn utilized to complete py loromyotomy. Results The operation was completed under laparos cope in 48 cases, while a conversion to open surgery was needed in 2 cases (1 c ase of prepyloric membrane and 1 case of pyloric mucosal injury, which were cure d by open repair). The operative time was 15~45 min (mean, 25 min). The nasogast ric tube was removed and oral feeding with milk was attempted 6 hours after the operation. The patients were discharged at 3~5 postoperative days. Follow-up for 3~6 months (mean, 4.5 months) in 42 cases showed that the patients were normall y developed. Conclusions Laparoscopic pyloromyotomy can be wel l performed in the presence of experience in open surgery, technical skills in l aparoscopy, effective anesthesia and proper surgical instruments.

Objective:To explore the effect of bifidobacterium tetravaccine tablets combined with low-dose erythromycin on the efficacy and motilin (MTL) levels in the treatment of children with functional dyspepsia (FD).Methods:One hundred and fifty children with FD admitted to Shanghai Public Health Clinical Center from January 2019 to June 2020 were selected and were divided into two groups by random number table, with 75 cases in each group. The control group was treated with bifidobacterium tetravaccine tablets, and the observation group was treated with low-dose erythromycin on the basis of control group. The clinical efficacy and the disappearance time of the clinical symptoms of the two groups were compared. The changes in the frequency of gastric antrum contraction (ACF), the amplitude of gastric antrum contraction (ACA), the gastric antral movement index (MI) were detected by ultrasonic developing-out unit before and after treatment. The levels of 5-hydroxytryptamine (5-HT), nitric oxide (NO), gastrin (GAS) and MTL were detected before and after the treatment using enzyme linked immunosorbent assay. The incidence of adverse reactions was counted. The recurrence rate was recorded after 6 months of the treatment.Results:The total effective rate in the observation group was higher than that in the control group:93.33% (70/75) vs. 78.67% (59/75), and the difference was statistically significant ( χ2 = 6.700, P<0.05). The disappearance time of symptoms of nausea and vomiting, loss of appetite, abdominal distension, and abdominal pain in the observation group were shorter than those in the control group: (2.58 ± 0.45) d vs. (3.22 ± 0.68) d, (3.56 ± 0.62) d vs. (4.10 ± 0.70) d, (2.54 ± 0.46) d vs. (3.24 ± 0.69) d, (2.66 ± 0.56) d vs. (3.40 ± 0.67) d, and the differences were statistically significant ( P<0.05). The levels of ACF, ACA and MI in the observation group after the treatment were higher than those in the control group: (4.32 ± 0.90) times/min vs. (3.58 ± 0.83) times/min, (0.34 ± 0.12) vs. (0.30 ± 0.10) mm, (1.33 ± 0.42) vs. (1.14 ± 0.30), and the differences were statistically significant ( P<0.05). The levels of 5-HT and NO in the observation group after the treatment were lower than those in the control group: (164.77 ± 30.34) mg/L vs. (184.45 ± 28.90) mg/L, (38.27 ± 10.20) mmol/L vs. (46.54 ± 9.48) mmol/L; and the levels of GAS and MTL were higher than those in the control group: (115.23 ± 15.70) ng/L vs. (98.50 ± 14.29) ng/L, (266.67 ± 32.76) ng/L vs. (238.40 ± 28.97) ng/L, and the differences were statistically significant ( P<0.05). Conclusions:The treatment of pediatric FD with bifidobacterium tetravaccine tablets combined with low-dose erythromycin can significantly improve the efficacy, quickly improve the clinical symptoms of children, promote physical recovery, and regulate MTL levels to improve gastric motility. The recurrence rate is low.
