OBJECTIVETo explore an ideal method of digestive tract reconstruction and tolerance to adjuvant chemotherapy after radical proximal gastrectomy.

METHODSThirty patients in the reconstruction group were treated by jejunal interposition, and other 30 patients received gastroesophagostomy (control group). The operation time, operation risk, occurrence of reflux esophagitis and postoperative 1-, 3-, 6-month nutrition statuses were evaluated. Forty-three patients received postoperative adjuvant chemotherapy with mFOLFOX-6 and tolerance to the chemotherapy was assessed.

RESULTSThe operation time of the reconstructional group was (162.2 ± 14.0)min and that of the control group was (137.6 ± 18.9)mi, with a statistically significant difference. (t = -5.7, P<0.01). There were no significant differences of operation risk, postoperative 2-, 4-, and 6-day C-reactive protein, 2-, 4- and 6-day systemic inflammatory response syndrome between the two groups. The differences of the occurrence of postoperative 1-, 3- and 6-month reflux esophagitis and 3- and 6-month nutritional status between the two groups were statistically significant. 18 of 19 (94.7%) patients in the reconstruction group completed all six cycles of chemotherapy, 24 patients in the control group received chemotherapy, and 12 (50.0%) of them completed 6 cycles of chemotherapy. There was a significant difference in the completion rate of chemotherapy of the two groups (P<0.05).

CONCLUSIONSThe postoperative complications of jejunal interposition are not inceased, the symptoms of reflux esophagitis are alleviated, the quality of life can be improved, and there is a better tolerance to adjuvant chemotherapy. Therefore, jejunal interposition after radical proximal gastrectomy is a rational method of digestive tract reconstruction.

OBJECTIVETo evaluate the efficacy and safety of oxymatrine in the treatment of chronic hepatitis B.

METHODSA multicenter randomized double-blind placebo-controlled trial was conducted. A total of 144 patients with chronic hepatitis B entered the study for 52 weeks; of them 72 received oxymatrine, and 72 received a placebo. Before and after the treatment, clinical symptoms, liver function, serum hepatitis B virus markers, and adverse drug reactions were observed.

RESULTSIn 144 patients, 14 were dropped and excluded due to inconsistencies in the included standard. Therefore, the efficacy and safety of 130 patients were analyzed. After being treated for 52 weeks, 70.77% of the patients in the study group had a normal ALT level, and in 43.08% and 33.33% their HBV DNA and HBeAg became negative. In the placebo group, 39.68% had normal ALT level, and 12.31% and 3.33% had their HBV DNA and HBeAg become negative. The rates of complete response and partial response in the oxymatrine group were 23.08% and 58.46%, and in the placebo group they were 3.08% and 44.62%. They were significantly higher in the oxymatrine group than in the placebo group. In the oxymatrine treated patients, 12 weeks after its withdrawal, 60.00% had a normal ALT level, 41.54% and 23.33% had both HBV DNA and HBeAg negative. In the placebo group, 31.75% had a normal ALT level, 3.08% and 1.67% had both HBV DNA and HBeAg negative. The rates of complete response and partial response in the oxymatrine group were 21.54% and 47.69%, and in the placebo group they were 0 and 41.54%. They were significantly higher in the study group than in the placebo group. The adverse reaction rates of oxymatrine in the study and the placebo group were 7.69% and 6.15%, respectively, but there was no statistical significant difference between them.

CONCLUSIONOxymatrine is an effective and safe agent for the treatment of chronic hepatitis B.

We report a case of mucormycosis induced by Cunninghamella spp. infection in a ten-year-old girl with acute lymphoblastic leukemia, who developed fever and respiratory symptoms after chemotherapy and was diagnosed with invasive fungal disease. Peripheral blood DNA sequences were analyzed using metagenomic next-generation sequencing (mNGS), and by comparison with the Pathogens Metagenomics Database (PMDB), we identified Cunninghamella spp. with sequence number 514 as the pathogen. The patient was treated with amphotericin B combined with posaconazole and showed a favorable response. We searched Pubmed, Embase, CNKI, and Wanfang database for reports of cases of Cunninghamella spp. infection in children and retrieved 22 reported cases (including 12 males) with a median age of 13.5 (3-18) years. In these 22 cases, hematological malignancy was the most common underlying condition (19/22), and most of patients experienced an acute onset and rapid progression with respiratory symptoms (14/20) and fever (16/20) as the most common symptoms. CT imaging often showed unilateral lesions with varying imaging findings, including pulmonary nodules or masses, infiltrative changes, and pleural effusion. Definite diagnoses were established in 18 of the cases, and 4 had probable diagnoses; the lungs and skin were the most frequent organs compromised by the infection. A definite diagnosis of Cunninghamella spp. infection still relied on histopathological examination and fungal culture, but the molecular techniques including PCR and mNGS had shown potentials in the diagnosis. Almost all the cases received antifungal treatment after diagnosis (21/22), and 13 patients also underwent surgeries. Death occurred in 9 (42%) of the cases at a median of 19 (4-54) days after onset of the signs or symptoms. The patients receiving antifungal therapy combined with surgery had a high survival rate (9/13, 69%) than those with antifungal therapy alone (3/8, 37%). Invasive fungal disease is a common complication in immunoco-mpromised patients, but Cunninghamella spp. infection is rare and has a high mortality rate. In cases highly suspected of this disease, active diagnosis and early treatment are critical to improve the survival outcomes of the patients.

Objective: To compare the efficacy between laparoscopic and open proximal gastrectomy with double-tract reconstruction for Siewert type II and III adenocarcinoma of the esophagogastric junction (AEG). Methods: A retrospective cohort study was conducted. Inclusion criteria: (1) 18 to 80 years old; (2) Siewert II and III AEG was confirmed by preoperative gastroscopy and biopsy, which could not be resected by endoscopy; patients undergoing radical proximal gastrectomy with double-tract reconstruction; (3) contrast-enhanced abdominal CT staging was cT1-2N0M0; (4) Eastern Cooperative Oncology Group (ECOG) physical status score <2 points, American Association of Anesthesiologists (ASA) grade 1 to 2; (5) patients agreed to perform proximal gastrectomy and signed an informed consent. Those who had undergone neoadjuvant radiochemotherapy, suffered from serious mental diseases and had incomplete data were excluded. According to the above criteria, clinical data of 84 consecutive patients with Siewert II and III AEG undergoing surgery at General Surgery Department of The Affiliated Tumor Hospital of Zhengzhou University from October 2010 to December 2018 were collected and analyzed. Of 84 patients, 61 underwent open proximal gastrectomy with double-tract reconstruction (OPG group), while 23 underwent laparoscopic proximal gastrectomy with double-tract reconstruction (LPG group). The perioperative complications and postoperative reflux esophagitis of two groups were compared. A P-value of <0.05 was considered to be statistically significant. Results: Among 84 cases, 74 were male and 10 were female. There were 43 cases of Siewert type II and 41 cases of Siewert type III. There were no significant differences in age, gender, body mass index, comorbidities, Siewert type, and tumor staging between the two groups (all P>0.05). As compared to the OPG group, the LPG group had longer operation duration [(223±21) minutes vs. (161±14) minutes, t=15.352, P<0.001], less intraoperative blood loss [195 (150, 215) ml vs. 208 (192, 230) ml, Z=2.143, P=0.032], and shorter time to flatus [(2.8±0.7) days vs. (3.3±0.9) days, t=2.477, P=0.015]. There were no significant differences in the number of harvested lymph nodes, time to the first meal and postoperative hospital stay between the two groups (all P>0.05). Postoperative complications developed in 2 cases (8.7%, 1 case each for anastomotic leakage and intestinal obstruction) in the LPG group and 5 cases (8.2%, 1 case each for anastomotic leakage, anastomotic bleeding, and anastomotic stenosis, 2 cases of incision infection) in the OPG group (χ(2)=5.603, P=0.231). The median follow-up was 41.2 (12.8-110.5) months. One patient (1.6%,1/61) had obvious reflux symptoms in the OPG group, compared with none in the LPG group (χ(2)=0.644, P=0.422). Esophagitis occurred in 1 case (4.8%, 1/21) in LPG group, compared with 4 patients (7.1%, 4/56) in the OPG group, without significant difference between the two groups (χ(2)=0.505, P=0.477). Conclusion: Laparoscopic proximal gastrectomy with double-tract reconstruction is safe and feasible without increasing the risk of postoperative complication and reflux esophagitis.
