Gastric cancer with peritoneal metastasis (GCPM) is a common and lethal manifestation of advanced gastric cancer, with a median survival of only 5-11 months. This consensus was developed by 30 experts from Asia (China, Japan, Korea, and Singapore) using the Delphi method and the GRADE evidence grading system. A total of 29 statements were formulated, covering the diagnosis and assessment of GCPM, indications for laparoscopic exploration and NIPS (normothermic intraperitoneal and systemic treatment), treatment regimens, prevention and management of complications, criteria for conversion surgery, and postoperative intraperitoneal therapy. The consensus aims to standardize clinical practice and improve the prognosis of patients with GCPM.

Objective:Assisted traction technology is effective in increasing the rate of super minimally invasive surgery (SMIS) in patients with early gastric cancer (EGC), and shortening the operator′s learning curve. We adopt the variable angle traction technique of tissue clamp dental floss as a traction technique in this research.Methods:Patients with early gastric cancer who were treated with SMIS - non full layer resection of EGC were enrolled in the First Medical Center of Chinese PLA General Hospital from January 2022 to June 2023. This research was carried out by experts at the same level. It was divided into two groups: traction and non-traction. Submucosal detachment time (SDT), submucosal detachment rate (SDS), lamina propria exposure, muscularis propria defect (MPD), bleeding during operation, block resection, surgical resection, hand operation expenses, and surgical instruments were recorded.Results:Nine patients adopted variable angle traction, and 9 patients did not. The overall resection rate and curative resection rate of both groups were 100%. The mean SDT time was 28.00 (21.00, 34.00) min in traction group and 56.00 (40.00, 85.00) min in non traction group. And it had statistical significance ( P = 0.005). The SDS was (0.58 ± 0.21) cm 2/min in traction group and (0.23 ± 0.10) cm 2/min in non-traction group. And it had statistical significance ( P<0.05). Exposure of intrinsic muscle layer (IML): 8 cases in the traction group and 6 cases in the non-traction group. Intraoperative IML injury: in the traction group, 8 cases were MPD-0 and 1 case was MPD-Ft; in the non-traction group, 4 cases were MPD-0, 1 case was MPD-Pt, and 4 cases were MPD-Ft. There was no statistical difference between the two groups in terms of intraoperative bleeding, hospitalization expenses, surgical expenses, and the total hospitalization time. There were no serious adverse reactions or outcomes. Conclusions:The variable angle traction method accelerates SDT and SDS for SMIS-non full layer resection of EGC. It has the advantages of the sufficient separation of IML and mucosal layer, the deeper dissection depth, the low injury of IML, low intraoperative bleeding, and no additional medical costs. Therefore, this method can become an auxiliary treatment technology for SMIS.

Objective To investigate the relationship between the therapeutic effect of anti-vascular endothelial growth factor(VEGF)and cytokines in aqueous humor in patients with diabetic retinopathy(DR).Methods From July 2023 to December 2023,50 DR patients(56 eyes)who were treated with anti-VEGF drugs in the Department of Ophthal-mology,the Third Affiliated Hospital of Xinxiang Medical University were included in this study.The patients were divided into the diabetic macular edema(DME)group(30 patients,36 eyes)and the proliferative DR(PDR)group(20 patients,20 eyes).Patients in the DME group received an intravitreal injection of aflibercept once a month for three consecutive times,with aqueous humor extracted before each injection.Patients in the PDR group received an intravitreal injection of aflibercept one week before vitrectomy,with aqueous humor extracted before injection and during vitrectomy,respective-ly.The concentrations of vascular endothelial growth factor A(VEGF-A),placental growth factor(PLGF),interleukin(IL)-1β,IL-23,IL-17A,and tumor necrosis factor-α(TNF-α)in the aqueous humor were detected using the Luminex as-say.Before injection therapy,all patients underwent best corrected visual acuity(BCVA)and central macular thickness(CMT)examinations,and their correlations with cytokine concentrations in DR patients before injection therapy were ana-lyzed.Results Compared to before injection therapy,the concentrations of VEGF-A,PLGF,and IL-23 in the aqueous humor of patients in the DME group decreased significantly after treatment(all P＜0.05);additionally,the CMT de-creased,and the BCVA increased(both P＜0.05).After injection therapy,the concentrations of VEGF,PLGF,IL-1β,IL-23,IL-17A,and TNF-α in the aqueous humor of patients in the PDR group significantly decreased compared to before injec-tion therapy(all P＜0.05).Before injection therapy,the levels of VEGF-A,PLGF,and IL-23 in the aqueous humor of pa-tients in the DME group were higher than those in the PDR group,and the differences were statistically significant(all P＜0.05).The correlation analysis results showed that before injection therapy,VEGF was negatively correlated with BCVA(r=-0.767,P=0.004)and was positively correlated with CMT(r=0.662,P=0.019)and IL-23(r=0.765,P=0.004)in the DME group.There was no correlation between the cytokines in the aqueous humor of patients in the PDR group be-fore injection therapy(all P＞0.05).Conclusion Changes in the concentration of VEGF-A,PLGF,and IL-23 are closely related to the occurrence and development of DR.Anti-VEGF treatment can improve BCVA and decrease CMT in DME pa-tients.The expression level of IL-23 in aqueous humor can serve as a predictive factor for the anti-VEGF efficacy in DR pa-tients,providing new targets for early diagnosis and treatment of DR.

The measurement results were analyzed according to the body height (divided into 3 groups: a 1.00 to 1.60 m group, a 1.61 to 1.70 m group, and a ≥1.71 m group) and gender using the software IBM SPSS 26.Results:The primary measures: ATPT was 37.0°±4.5°, and L1 and L2 were respectively (57.8±7.4) mm and (34.5±3.3) mm. The secondary measures: PSA 128.1°±5.4°, ATAA 52.7°±4.1°, APST 89.1°±5.9°, APD was (32.9±2.6) mm, LPTS (20.5±2.4) mm, and LTT (40.9±5.7) mm. After grouping by gender, there was no significant difference in PSA between men and women ( P>0.05) while there were significant differences in the other indexes between men and women ( P<0.05). After grouping by body height, there was no significant difference in ATPT, PSA, APST or ATAA between the 3 groups (1.00 to 1.60 m group, 1.61 to 1.70 m group and ≥1.71 m group) ( P>0.05) while there were significant differences in L1, L2, APD, LPTS and LTT between the 3 groups ( P<0.05). Conclusions:Based on the knee CT images, the primary measures of PCL low tibial tunnel are as follows: the angle between tibial plateau and tibial tunnel is 37.0°±4.5°, and the perpendicular distances from the tibial tunnel entrance and exit point to the tibial plateau are (57.8±7.4) mm and (34.5±3.3) mm, respectively. Gender and body height are the important factors influencing the above measurement outcomes.

Objective:To evaluate clinical efficacy and safety of topical compound oleum lithospermi in the treatment of mild to moderate diaper dermatitis.Methods:A multicenter, randomized, positive-drug parallel-controlled clinical trial was conducted in 19 hospitals from July 2019 to August 2020. Children aged 0 - 12 months with mild to moderate diaper dermatitis were enrolled and randomly divided into 2 groups using a random number table: test group topically treated with compound oleum lithospermi, and control group topically treated with zinc oxide cream. The treatment was carried out 6 - 8 times a day for 7 days. Visits were scheduled on days 0 and 7, and total response rate and clinical healing time were evaluated. Changes in the dermatitis family impact (DFI) score were compared between the test group and control group, and adverse events were recorded. Statistical analysis was carried out by using independent-sample t test for normally distributed continuous data, Wilcoxon rank sum test for non-normally distributed continuous data, and chi-square test or Fisher′s exact test for unordered categorical data; survival curves were drawn, and log-rank test was used for comparisons between two groups. Results:A total of 343 children with diaper dermatitis were enrolled in this study. Among them, 31 children violated the protocol, so 312 were included in the per protocol set, including 157 in the test group and 155 in the control group, and all completed the visits on days 0 and 7. The total response rate was significantly higher in the test group (87.26%, 137/157) than in the control group (78.71%, 122/155; χ2 = 4.04, P = 0.044) . The clinical healing time was significantly shorter in the test group (5.33 days) than in the control group (6.13 days; χ2 = 4.67, P = 0.025) . After 7-day treatment, the DFI score significantly decreased in both the 2 groups compared with that before the treatment, but there was no significant difference in the DFI score between the 2 groups (test group: 4.02 ± 6.96, control group: 3.58 ± 5.90, Z = -0.39, P = 0.686) . The incidence of adverse events was 2.92% (5/171) and 5.45% (9/165) in the test group and control group respectively, and there was no significant difference between the 2 groups ( χ2 = 0.03, P = 0.865) . Conclusion:Compound oleum lithospermi can markedly reduce the clinical severity of diaper dermatitis, improve the total response rate, shorten the clinical treatment period, and improve the quality of life of children′s families with a favorable safety profile.

Objective:To compare the efficacy of open surgery and arthroscopic assisted surgery in treatment of knee dislocations.Methods:A retrospective case-control study was conducted to analyze the clinical data of 80 patients with knee dislocations admitted to Second Hospital of Lanzhou University from May 2013 to September 2019, including 59 males and 21 females, aged 18-66 years [(42.5±11.6)years]. Open multiple ligament reconstruction was performed in 49 patients (open group) and arthroscopic assisted multiple ligament reconstruction was performed in 31 patients (arthroscopic group). The postoperative hospitalization days, incidence of complications, time needed for recovery of knee range of motion (>0°, >90°, >120°), and time to complete weight-bearing were compared between the two groups. The Lysholm score, international knee documentation committee (IKDC) subjective knee form, Tegner activity level, score of the MOS item short-form health survey (SF-36), patient satisfaction and knee range of motion were compared between the two groups at the last follow-up.Results:All the patients were followed up for 1.2-7.4 years [(3.8±1.5)years]. There was no significant difference in postoperative hospitalization days or incidence of complications between the two groups ( P>0.05). No significant difference was found in time needed for recovery of knee range of motion (>0°, >120°) or time to complete weight-bearing ( P>0.05). The time needed for recovery of knee range of motion (>90°) was 90(60, 90)days in open group and 60(30, 90)days in arthroscopic group ( P<0.05). At the last follow-up, there was no significant difference in Lysholm score, IKDC subjective score, Tegner activity level, SF-36 score, or patient satisfaction between the two groups ( P>0.05). At the last follow-up, the knee range of motion was 120°(90°, 130°) in open group and 135°(120°, 140°) in arthroscopic group ( P<0.05). Conclusion:For treatment of knee dislocations, open surgery and arthroscopic assisted surgery have similar results in the long-term effect, while arthroscopic assisted surgery has benefits in early rehabilitation and ultimately better knee range of motion.
