In order to promote the innovative application of Sanjiao theory and Yingwei theory， this paper tries to apply the ''Sanjiao-Yingwei'' Qi transformation theory to the treatment of tumor diseases， integrating it with T cell exhaustion mechanism to elaborate on its scientific connotation and using network pharmacology and bioinformatics to elucidate the correlation between the anti-tumor mechanism of ''Sanjiao-Yingwei'' Qi transformation and T cell exhaustion. The ''Sanjiao-Yingwei'' Qi transformation function is closely related to the immunometabolic ability of the human body， and the ''Sanjiao-Yingwei'' Qi transformation system constitutes the immunometabolic exchange system within and outside the cellular environment. Cancer toxicity is generated by the fuzzy Sanjiao Qi， and the long-term fuzzy Sanjiao Qi is the primary factor leading to T cell exhaustion， which is related to the long-term activation of T cell receptors by the high tumor antigen load in the tumor microenvironment. Qi transformation malfunction of the Sanjiao produces phlegm and collects stasis， which contributes to T cell exhaustion and is correlated with nutrient deprivation， lipid accumulation， and high lactate levels in the immunosuppressed tumor microenvironment， as well as with the release of transforming growth factor-β and upregulated expression of programmed death receptor-1 by tumor-associated fibroblasts and platelets in the tumor microenvironment. Ying and Wei damage due to Sanjiao Qi transformation malfunction is similar to the abnormal manifestations such as progressive loss of exhausted T cell effector function and disturbance of cellular energy metabolism. Guizhi decoction， Shengming decoction， and Wendan decoction can correct T cell exhaustion and exert anti-tumor effects through multi-target and multi-pathways by regulating ''Sanjiao-Yingwei'' Qi transformation， and hypoxia inducible factor-1α （HIF-1α） may be one of the main pathways to correct T cell exhaustion. It was found that HIF-1α may be one of the important prognostic indicators in common tumors by bioinformatics. The use of the ''Sanjiao-Yingwei'' Qi transformation method may play an important part in improving the prognosis of tumor patients in clinical practice.

BACKGROUND:Oleic acid can regulate inflammation and immune responses,and has the potential to repair skin wounds.Oleic acid has a short retention time at the lesion.It is prone to self oxidation and deterioration in the air,and suitable drug carriers are needed to fully exert the therapeutic effect of oleic acid. OBJECTIVE:To investigate the efficacy of oleic acid-liposome gel in the treatment of chronic burn wounds. METHODS:Oleic acid liposome solution was prepared by thin film dispersion method,and then dissolved in Poloxamer gel matrix to prepare oleic acid-liposome gel.(1)In vitro experiment:Oleic acid-liposome gel solution was prepared by adding different volumes of oleic acid-liposome gel into cell medium(volume ratio:1:3,1:9,1:27,respectively).Alma-blue reagent was used to detect the effects of different concentrations of oleic acid-liposome gel on the proliferation of human keratinocytes and human fibroblasts.Crystal violet staining was used to observe cell morphology.(2)In vivo experiment:The animal model of chronic burn wounds was established by using full-thickness burn of SD rat back skin combined with local subcutaneous injection of epirubicin.The 30 successfully modeled rats were randomly divided into five groups with six rats in each group.The wounds of oleic acid liposome gel group,oleic acid group,liposome gel group,positive control group and negative control group were applied with gauze of oleic acid liposome gel,oleic acid,liposome gel,recombinant human epidermal growth factor gel and normal saline.The dressing was changed once every other day.A total of 16 doses were administered.The wound healing was observed. RESULTS AND CONCLUSION:(1)In vitro experiments:Alma-blue reagent detection and crystal violet staining showed that oleic acid liposome gel solution with volume ratio of 1:9 could promote the proliferation of human keratinocytes and human fibroblasts.(2)In vivo experiment:The wound healing time of the oleic acid liposome gel group was shorter than that of the other four groups(P＜0.01),and the wound healing rate at 4,8,12,16,and 20 days was higher than that of the other four groups(P＜0.01).After administration,hematoxylin-eosin staining showed epithelialization and healing of wounds in all five groups,and the epidermal thickness of oleic acid liposome gel group was the closest to normal skin and better than the other four groups.Immunohistochemical staining showed that the expressions of cytokeratin 10,tumor protein 63,α-smooth muscle actin,collagen I,tumor necrosis factor α,interleukin 6,malonaldehyde,and superoxide dismutase in oleic acid liposome gel group were closest to those in normal skin,and superior to those in other four groups.On days 12 and 32 of administration,the expressions of tumor necrosis factor α,interleukin 6,malondialdehyde,and superoxide dismutase in wound homogenate supernatant in oleic acid liposome gel group were closest to those in normal skin,and superior to those in other four groups.(3)The results showed that oleic acid liposome gel could promote the proliferation of keratinocytes and fibroblasts,reduce inflammation and oxidative stress injury,and promote the healing of chronic burn wounds.

ObjectiveTo explore the effect and possible molecular mechanism of Qinghua Yichang Formula （清化益肠方， QYF） in treating acute radiation-induced intestinal injury mice via NOD-like receptor thermal protein domain associated protein 3 （NLRP3）. MethodsSixty C57BL/6J mice were randomly divided into control group， model group， pre-modeling medication group， post-modeling medication group， inhibitor group， and QYF plus inhibitor group， with 10 mice in each group.Except for the control group， the other five groups were irradiated with a single full dose to establish the acute radiation-induced intestinal injury mice model. The pre-modeling medication group and the QYF plus inhibitor group were continuously given 4 g/ml of QYF decoction by gavage before modeling， 0.2 ml each time， once a day for 7 days. The post-modeling medication group， pre-modeling medication group and QYF plus inhibitor group were given 4 g/ml of QYF decoction for 14 days after modeling. The control group， model group and inhibitor group were given 0.2 ml of normal saline once a day for 14 consecutive days. Two hours after irradiation， the inhibitor group and the QYF plus inhibitor group were given an intraperitoneal injection of 0.2 ml of the NLRP3 inhibitor MCC950 （concentration： 10 mg/kg）， once every two days. To observe the pathological changes in intestinal tissues， hematoxylin-eosin （HE） staining was used. Western blotting and RT-qPCR were used to detect the protein and mRNA expression levels of NLRP3 in intestinal tissues. Immunohistochemistry was used to detect the expression level of NLRP3， Caspase-1 and GSDMD in intestinal tissues. The proportion of CD4⁺ and CD8⁺ T cells in the spleens of mice were detected by flow cytometry. ELISA was used to determine the levels of IFN-γ， IL-18， and IL-1β in mice serum. ResultsHE staining showed no lesions in the intestinal tissue of mice in the control group. The mice in the model group had shortened intestinal villi， thinned mucosal layers， multifocal mucosal necrosis in the lamina propria， and local neutrophil infiltration. The pathological damage of intestinal tissue of mice in each medication group was improved to varied degrees， among which the QYF plus inhibitor group showed most obvious improvement. Compared to those in the control group， the protein and mRNA expression levels of NLRP3 in the intestinal tissue of mice in the model group significantly increased， with higher NLRP3， Caspase-1， and GSDMD protein expression in the intestinal tissue， increased proportion of CD4⁺ T cells in spleen， decreased proportion of CD8⁺ T cells， and increased levels of IFN-γ， IL-18 and IL-1β in serum （P＜0.05）. Compared to those in the model group， the above indicators in the other medication groups were all improved （P＜0.05）.The NLRP3， Caspase-1， and GSDMD proteins in the pre-modeling medication group were lower than those in the post-modeling medication group （P＜0.05）； and the NLRP3 mRNA level in the QYF plus inhibitor group was lower than that in the inhibitor group （P＜0.05）. ConclusionQYF may play a role in preventing and treating acute radiation-induced intestinal injury by inhibiting the expression of NLRP3.

Objective:To analyze the characteristics of cervical lymph node metastasis in tongue squamous cell carcinoma (TSCC).Methods:A retrospective study was conducted. A total of 329 patients with TSCC who underwent en bloc resection of primary tumor and neck dissection in the Second Xiangya Hospital of Central South University from June 2010 to March 2018 were included. There were 283 males and 46 females, aged from 26 to 80 years. All patients underwent the modified neck dissection. The main difference between the modified neck dissection and the traditional neck dissection lay in the managements of unconventional lymph nodes. The lymphatic adipose tissues adjacent to the superior thyroid artery, the base of facial artery and the branches of external carotid artery were thoroughly dissected. The primary tumor as well as lingual artery, tissues along the lingual artery and lymph nodes in the mouth floor were resected. χ 2 test was used for comparison of count data, and linear regression model was used for multivariate analysis. Results:Cervical lymph node metastases were found in 136 patients (41.3%). Among 142 patients (T1-2cN0) with supraomohyoid neck dissection, 22 patients had pathologically occult lymph node metastases (15.5%), with a 5-year overall survival rate of 90.2%, which was similar to the 5-year overall survival rate of 92.1% in 120 patients without lymph node metastasis (χ 2=0.156, P=0.693). Multivariate linear regression analysis showed that T stage, clinical stage and unconventional lymph node metastasis were important factors for cervical lymph node metastasis in tongue cancer patients ( P<0.05). Unconventional lymph node metastases occurred in 30 patients (9.1%), including the metastases of lymph nodes in the floor of mouth (3.0%), the lingual artery (2.4%), the base of the external maxillary artery (2.1%), the superior thyroid artery (0.9%), and the external carotid artery (0.6%). There were significant differences in the unconventional lymph node metastasis rates between patients with negative and positive conventional lymph node metastases [4.9%(10/203) vs. 15.9%(20/126), χ 2=11.242, P=0.001] and also between patients with depth of invasion ≤5 mm, 5 mm 10 mm [3.1%(2/64) vs. 5.7%(6/106) vs. 13.8%(22/159), χ 2=7.907, P=0.005]. Conclusion:Supraomohyoid neck dissection can achieve reliable control efficacy in patients with cN0 tongue cancer. All patients with lymph node dissection should undergo unconventional lymph node dissection. Unconventional lymph node dissection is strongly recommended for patients with conventional lymph node metastasis.

Objective To conduct a network meta-analysis on the effectiveness of first-line immunotherapy on patients with brain metastases from advanced non-small cell lung cancer(NSCLC).Methods Two investigators conducted a computerized search of Pubmed,Embase,Cochrane,and other databases to screen the literature,extract the information,and assess the risk of bias of the included studies.The included clinical trials were statistically analyzed using R(4.1.3)software.For the study outcome indicators OS and PFS,the risk ratios(HRs),and the 95%confidence intervals(CIs)were extracted from the included studies and logarithmically transformed into effect analysis statistics.Results Six randomized controlled trials were finally included,including 327 patients with non-excludable NSCLC brain metastases.Network meta-analysis suggested that PD-1 inhibitor+CTLA-4 was more advantageous than the conventional chemotherapy for enhancing patients'OS(HR:0.13,95%CI:0.03-0.71),followed by PD-L1 inhibitor(HR:0.17,95%CI:0.04-0.74)and PD-1 inhibitor+chemotherapy(HR:0.36,95%CI:0.2-0.63).PD-1 inhibitor+CTLA-4 was also more advantageous(HR:0.37,95%CI:0.15-0.93)than the conventional chemotherapy for boosting patients'PFS,followed by PD-L1 inhibitor+chemotherapy(HR:0.44,95%CI:0.29-0.66)and PD-1 inhibitor(HR:0.48,95%CI:0.27-0.86).Conclusion Immune checkpoint inhibitor therapy improves the survival of patients with brain metastases from advanced NSCLC.In particular,the combination of PD-1 inhibitor and CTLA-4 inhibitor show excellent survival benefit.

ObjectiveTo investigate the relationship between mosquito density fluctuations and meteorological factors, so as to provide a scientific basis for mosquito surveillance analysis, risk assessment, and comprehensive prevention and control. MethodsMosquito surveillance and monitoring data of 2020‒2023 was obtained from on-site supervisory sampling by Songjiang Center for Disease Control and Prevention, and meteorological data was obtained from the Wheat A wheat malt-agro-meteorological big data system. Excel 2019 and SPSS 25.0 software were used to organize and analyze the mosquito number, species composition, and seasonal changes in mosquito density captured by the CO₂-light trap at rach monitoring site. Circular distribution method was used to calculate the peak time of mosquito density, combined with the meteorological data of the same period to explore the impact of meteorological factors on the results of mosquito surveillance. ResultsThere was a statistical difference in the overall distribution of mosquito quantity in different habitats(H=23.11, P<0.05), 2020‒2023. In addition, the results showed that July 28th was the peak day for mosquito density, and the duration from June 13th to September 11th was the seasonal peak period for mosquitoes. Pearson correlation analysis showed a positive correlation between mosquito density and average air temperature, average highest air temperature, average lowest air temperature, extreme maximum air temperature, extreme minimum air temperature, precipitation, and number of precipitation days (all P<0.01). While, there was no significant correlation between average wind speed and mosquito density (P>0.05). Multiple stepwise regression analysis resulted in the equation of Y=0.151X_{extreme minimum temperature}+0.321X_{number of precipitation days}+1.002X_{SQRT precipitation}-1.288 (F=102.635, P<0.05). ConclusionThe CO₂-light trap is advisable to monitor the habitats of farmers, livestock sheds, residential areas, parks, hospitals, and other external environments. Air temperature and precipitation have a significant impact on mosquito density. It is recommended to implement comprehensive prevention and control measures to reduce mosquito density and prevent mosquito-borne diseases before the peak period of mosquitoes.

Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Objectives:To investigate the short-term efficacy of oblique lateral interbody fusion(OLIF)in treating mild-to-moderate lumbar spinal stenosis(LSS).Methods:35 patients with mild-o-moderate LSS treated with OLIF between May 2018 and May 2020 were analyzed retrospectively,including 25 males and 10 females,aged 50-74(60.3±10.7)years old.The patients were followed up for 12-28(18.3±3.7)months.The operative time,intraoperative bleeding,and complications were recorded;At preoperation,1 week,and 3,6 and 12 months after surgery,the visual analogue scale(VAS)for lumbar and leg pain and Oswestry disability index(ODI)were compared to evaluate clinical efficacy;And lumbar X-ray,CT,and MRI were performed at the same time to measure and evaluate the height of the intervertebral space,size of intervertebral foramen,area of dural sac and sagittal diameter,lordotic angle of intervertebral space,lordotic angle of lumbar spine,and their respective differences between before and after operation,as well as between each postoperative time point were analyzed;The complications and fusion conditions at each time point were also documented.Results:The operative time was 30-100(70.5±20.3)min,and intraoperative bleeding was 20-120(60.3±20.2)mL.The lumbar and leg pain VAS scores and ODI at postoperative 1 week,and 3,6 and 12 months were signif-icantly improved compared with those before operation,and the differences were statistically significant(P＜0.05),while there was no statistical significance when compared pairwisely between postoperative time points(P＞0.05).At postoperative 1 week,and 3,6 and 12 months,the intervertebral space height,intervertebral lor-dotic angle and lumbar lordotic angle,left and right intervertebral foramina sizes,dural sac areas,and sagittal diameters increased significantly compared with those before operation,with statistically significance(P＜0.05),and no statistical difference was found when compared pairwisely between postoperative time points for each imaging parameter(P＞0.05).According to the CT image evaluation 1 year after operation,the overall fusion rate was 94.2％(33/35 cases).No serious complications such as nerve and vascular injury occurred;3 cases of postoperative hip flexion weakness and anterior thigh numbness were relieved after 1 month of symptomatic treatment with conservative therapy;2 cases of fusion device sinking of end-plate cutting were revised in the second stage and underwent posterior muscular gap approach internal fixation.Conclusions:OLIF has satisfactory short-term clinical efficacy in the treatment of mild-to-moderate LSS.

Objective To investigate the therapeutic effect of segmental decompression combined with corrective short-segment fusion surgery for the treatment of degenerative lumbar scoliosis.Methods In total,124 patients with degenerative lumbar scoliosis were selected and divided into short-and long-segment fusion groups using the random number table method,with 62 patients in each group.Posterior short-segment decompression,fixation,and fusion were performed in the short-segment fusion group;the fusion segment was the adjacent lumbar vertebra.Posterior long-segment decompression,fixation,and fusion were performed in the long-segment fusion group;the fusion segments included multiple adjacent lumbar vertebrae.At the 6th month after surgery,the coronal Cobb angle of lumbar convexity,sagittal Cobb angle of lumbar lordosis,intervertebral foramen height,intervertebral space height,intervertebral foramen area,spinal canal area,spinal canal diameter,Japanese Orthopedic Association(JOA)score,Oswestry Disability Index(ODI),degree of pain in the lower back and lower limbs,and postoperative complications were compared between the groups.Results The Cobb angle of the coronal lumbar scoliosis in the short-and long-segment fusion groups was significantly higher than that before surgery(P<0.05).At the 6th month after surgery,the intervertebral foramen height,intervertebral space height,intervertebral foramen area,spinal canal area,and spinal canal diameter in both groups increased,and those in the short-segment fusion group were higher than those in the long-segment fusion group(P<0.05);at the 6th month after the operation,the JOA scores of the short-segment and long-segment fusion groups were higher than those before surgery,and the JOA score of the short-segment fusion group was higher than that of the long-segment fusion group(P<0.05).The ODI score was lower than that before surgery in the short-and long-segment fusion groups,and the ODI score in the short-segment fusion group was lower than that in the long-segment fusion group(P<0.05).At the 6th month after surgery,the pain scores of the lower back and lower limbs in the short-and long-segment fusion groups were significantly higher than those before surgery(P<0.05).There were two cases of dural tears during decompression caused by lamina dura adhesion in the long-segment fusion group,and no serious complications were observed in the short-segment fusion group.Conclusions Both short-and long-segment decompression fixation fusion using a posterior approach can achieve good therapeutic effects for treating degenerative lumbar scoliosis.However,compared to the long-segment fusion group,the short-segment fusion group undergoing short-segment decompression fixation fusion through a posterior approach had a shorter surgical period,lower intraoperative blood loss,better recovery of lumbar function,and a lower risk of postoperative complications.

Transcatheter aortic valve implantation (TAVI) is an important alternative in treating high-risk patients with aortic valve regurgitation. Transcatheter tricuspid valve implantation (TTVI) is also an important treatment option for high-risk patients with tricuspid regurgitation. We reported a 72-year male patient who underwent TAVI due to severe aortic valve regurgitation using a J-Valve. During a two-year follow-up, the patient developed secondary tricuspid regurgitation to atrial fibrillation, and subsequently received TTVI using a LuX-Valve. Following the interventions, the patient's symptoms were significantly improved, and echocardiography indicated good hemodynamic performance of both transcatheter heart valves. This case highlights the feasibility and effectiveness of performing multiple valve implantations via transcatheter approaches in high-risk elderly patients.
