Objective:To investigate the diagnostic value of plasma cytokines such as interleukin (IL)-2, IL-6 and interferon (IFN)-γ in non-Hodgkin lymphoma (NHL).Methods:A retrospective case-control study was conducted. A total of 48 NHL patients admitted to the Second Affiliated Hospital of Xuzhou Medical University between January 2020 and December 2022 were selected as NHL group, and another 34 healthy people who underwent physical examimation during the same period were selected as the healthy control group. The levels of IL-2, IL-4, IL-6, IL-10, IL-17, tumor necrosis factor (TNF) - α and IFN-γ in the plasma of patients at first admission and healthy subjects during physical examination were detected by using flow cytometry. The differences in general data and all cytokines levels of both groups were compared. The collinearity stepwise screening was made in 7 cytokines levels, and the screened variables were included in multivariate binary logistic regression model. Plasma cytokines with independent effects on the pathogenesis of NHL were screened. Taking local biopsy, histopathological examination or immunohistochemical examination as the gold standard, the receiver operating characteristic (ROC) curves of individual and combined diagnosis of NHL based on the selected cytokines were drawn to judge the diagnostic effect of all indicators on NHL.Results:There were 32 males (66.7%) and 16 females (33.3%) in NHL group, with the median age [ M ( Q1, Q3)] of 56.50 (45.75, 67.50) years; there were 28 males (82.4%) and 6 females (17.6%) in the healthy control group, with the median age of 52.00 (47.50, 55.50) years. There were no statistically significant differences in age and gender composition between the 2 groups (all P > 0.05). The levels of IL-2 [1.44 (1.36, 1.85) pg/ml vs. 1.19 (0.86, 1.68) pg/ml] and TNF-α [3.46 (2.68, 4.06) pg/ml vs. 2.23 (1.52, 3.46) pg/ml] in NHL group were higher than those in the healthy control group, and the differences were statistically significant (all P < 0.05). There were no statistically significant differences in IL-4, IL-6, IL-10, IL-17, IFN-γ levels (all P > 0.05). According to collinear stepwise screening of independent variables, IL-4 and TNF-α were excluded from 7 cytokines, and the other 5 cytokines were included in multivariate logistic regression model, and the result showed that the decreased level of IL-2 ( OR = 0.20, 95% CI: 0.08-0.53, P = 0.001) and the increased levels of IL-6 ( OR = 1.18, 95% CI: 1.04-1.33, P = 0.009) and IFN-γ ( OR = 1.26, 95% CI: 1.08-1.46, P = 0.003) were independent risk factors for the onset of NHL. The results showed that the area under the curve of IL-2, IL-6, IFN-γ and the combination of 3 indexes for the diagnosis of NHL was 0.760 (95% CI: 0.651-0.870), 0.595 (95% CI: 0.468-0.722), 0.508 (95% CI: 0.373-0.642), 0.847 (95% CI: 0.763-0.930), and the optimal cut-off value of the combination of 3 indexes was 0.730 which was calculated by logistic regression model formula; the corresponding sensitivity and specificity were 70.2% and 94.1%, respectively. Conclusions:The decreased level of IL-2 and increased levels of IL-6 and IFN-γ at initial diagnosis are risk factors for the onset of NHL. The combined detection of the 3 indexes shows a good value in the diagnosis of NHL.

Baitouweng Decoction is a classic prescription commonly used in the treatment of heat-toxin dysentery,with confirmed efficacy in the treatment of ulcerative colitis(UC).Clinical studies have found that Baitouweng Decoction,modified Baitouweng Decoction,combined with other Chinese materia medica or other therapies for UC can improve the clinical symptoms of patients,reduce the lesion activity score under colonoscopy,promote the healing of intestinal mucosal tissue,and also improve the overall efficiency of treatment,and reduce adverse reactions and recurrence rate.Pharmacological studies showed that Baitouweng Decoction may treat UC by regulating the expressions of related inflammatory factors and signaling pathways,regulating immune function,repairing intestinal mucosal barrier,and improving intestinal flora imbalance.This article systematically reviewed the clinical and basic research progress of Baitouweng Decoction in the treatment of UC,in order to provide a basis for relevant research.

Objective:To investigate the clinical features and therapeutic efficacy of patients with hereditary leiomyomatosis and renal cell carcinoma(RCC) syndrome-associated RCC (HLRCC-RCC) in China.Methods:The clinical data of 119 HLRCC-RCC patients with fumarate hydratase (FH) germline mutation confirmed by genetic diagnosis from 15 medical centers nationwide from January 2008 to December 2021 were retrospectively analyzed. Among them, 73 were male and 46 were female. The median age was 38(13, 74) years. The median tumor diameter was 6.5 (1.0, 20.5) cm. There were 38 cases (31.9%) in stage Ⅰ-Ⅱand 81 cases (68.1%) in stage Ⅲ-Ⅳ. In this group, only 11 of 119 HLRCC-RCC patients presented with skin smooth muscle tumors, and 44 of 46 female HLRCC-RCC patients had a history of uterine fibroids. The pathological characteristics, treatment methods, prognosis and survival of the patients were summarized.Results:A total of 86 patients underwent surgical treatment, including 70 cases of radical nephrectomy, 5 cases of partial nephrectomy, and 11 cases of reductive nephrectomy. The other 33 patients with newly diagnosed metastasis underwent renal puncture biopsy. The results of genetic testing showed that 94 patients had FH gene point mutation, 18 had FH gene insertion/deletion mutation, 4 had FH gene splicing mutation, 2 had FH gene large fragment deletion and 1 had FH gene copy number mutation. Immunohistochemical staining showed strong 2-succinocysteine (2-SC) positive and FH negative in 113 patients. A total of 102 patients received systematic treatment, including 44 newly diagnosed patients with metastasis and 58 patients with postoperative metastasis. Among them, 33 patients were treated with tyrosine kinase inhibitor (TKI) combined with immune checkpoint inhibitor (ICI), 8 patients were treated with bevacizumab combined with erlotinib, and 61 patients were treated with TKI monotherapy. Survival analysis showed that the median progression-free survival (PFS) of TKI combined with ICI was 18 (5, 38) months, and the median overall survival (OS) was not reached. The median PFS and OS were 12 (5, 14) months and 30 (10, 32) months in the bevacizumab combined with erlotinib treatment group, respectively. The median PFS and OS were 10 (3, 64) months and 44 (10, 74) months in the TKI monotherapy group, respectively. PFS ( P=0.009) and OS ( P=0.006) in TKI combined with ICI group were better than those in bevacizumab combined with erlotinib group. The median PFS ( P=0.003) and median OS ( P=0.028) in TKI combined with ICI group were better than those in TKI monotherapy group. Conclusions:HLRCC-RCC is rare but has a high degree of malignancy, poor prognosis and familial genetic characteristics. Immunohistochemical staining with strong positive 2-SC and negative FH can provide an important basis for clinical diagnosis. Genetic detection of FH gene germ line mutation can confirm the diagnosis. The preliminary study results confirmed that TKI combined with ICI had a good clinical effect, but it needs to be confirmed by the results of a large sample multi-center randomized controlled clinical study.

Objective:To compare the effects of transverse abdominis plane block and incision infiltration anesthesia on the early postoperative recovery in the patients undergoing thoracoscopic lung resection with general anesthesia.Methods:Eighty American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ patients, regardless of gender, aged 50-78 yr, with body mass index of 18-30 kg/m 2, scheduled for elective thoracoscopic lung resection under general anesthesia, were divided into 2 groups ( n=40 each) using a random number table method: incision local infiltration group (group D) and transverse abdominis plane block group (group E). In group E, the patients were changed to the lateral position after completion of anesthesia induction, ultrasound-guided transverse abdominis plane block was performed on the affected side, with 0.25% ropivacaine hydrochloride 30 ml injected. In group D, infiltration anesthesia with 0.25% ropivacaine hydrochloride was performed before incision. Postoperative patient-controlled intravenous analgesia was carried out, and flurbiprofen axetil was intravenously injected for rescue analgesia when the numerical rating scale score at rest >3 or numerical rating scale score≥6 while coughing. Quality of Recovery-15 scale scores were assessed at 1 day before surgery and 24 and 48 h after surgery. Plasma concentrations of interleukin-6 (IL-6) and IL-1β were measured by enzyme-linked immunosorbent assay before incision, at the end of surgery, and at 24 h after surgery. The amount of remifentanil used during surgery, the number of effective pressing times of patient-controlled analgesia within 48 h after surgery, requirement for rescue analgesia, first ambulation time after surgery, time to first flatus, length of hospital stay, and occurrence of nausea and vomiting and pulmonary infection within 48 h after surgery were recorded. Results:Compared with group D, Quality of Recovery-15 scale scores were significantly increased, the amount of remifentanil used during surgery and the number of effective pressing times of patient-controlled analgesia were reduced, the rate of rescue analgesia was decreased, the time to first rescue analgesia was prolonged, and the time to first flatus was shortened in group E ( P<0.05). There were no significant differences in the plasma concentrations of IL-6 and IL-1β at various time points, time to first ambulation after surgery, length of hospital stay, and incidence of nausea and vomiting and pulmonary infection between the two groups ( P>0.05). Conclusions:Compared with incision infiltration anesthesia, transverse abdominis plane block can reduce intraoperative consumption of opioids, alleviate postoperative pain, and promote early postoperative recovery when used for thoracoscopic lung resection under general anesthesia.

Objective To investigate the change in the function of the motor nerve fibers of the sciatic nerve of rat following injection of different neurolytic drugs. Methods Thirty-five SD rats weighing 350-380 g were randomly divided into 7 groups ( n = 5 each): group C received normal saline; group Ad adriamycin 5 mg/ml;group Aa anhydrous alcohol; group Pg1 8% phenol-glycerol; group Pg2 10% phenol-glycerol; group Pg3 12% phenol-glycerol and group Ci cidomycin 4000 U/ml. 0.2 ml of the different neurolytic drugs was injected at the points where the branches of the sciatic nerve entering semi-membranous and adductor magnus muscles. The action potential and conduction velocity of motor and sensory nerve fibers were measured at 21 d after injection. Results The conduction velocity of sensory nerve fibers was 0 in each group. The conduction velocity and action potential of the motor nerve fibers were significantly decreased in group Ad, Aa, Pg1, Pg2, Pg3 and Ci as compared with group C (the control group). The action potential and the conduction velocity were significantly higher in group Ad than in other neurolytic drug groups. The potential and the conduction velocity were the lowest in group Aa and Pg3.The conduction velocity in group Pg1, Pg2, Ci was comparable. Conclusion 5% adriamycin seems to be a better neurolytic drug with less interference with function of motor never fibers.
