Based on the viewpoint of "sweat pore-qi and liquid-kidney collaterals"， it is believed that children's nephrotic syndrome is caused by the core mechanism of sweat pore constraint and closure， qi and liquid imbalance， and kidney collaterals impairment， and it is proposed that the treatment principle is to nourish the sweat pore， regulate qi and fluid， and supplement the kidney and unblock the collaterals. In clinic， guided by sequential therapy and according to the different disease mechanism characteristics of the four stages， including early stage of the disease， hormone induction stage， hormone reduction stage， hormone maintenance stage， the staged dynamic identification and treatment was applied. For early stage of the disease with edema due to yang deficiency， modified Zhenwu Decoction （真武汤） was applied to warm yang and drain water； for hormone induction stage with yin deficiency resulting in effulgent fire， modified Zhibai Dihuang Pill （知柏地黄丸） plus Erzhi Pill （二至丸） was used to enrich yin and reduce fire； for hormone reduction stage with qi and yin deficiency， modified Shenqi Dihuang Decoction （参芪地黄汤） was used to boost qi and nourish yin； for hormone maintenance stage， modified Shenqi Pill （肾气丸） was used to supplement yin and yang. Meanwhile， the treatment also attaches importance to the combination of vine-based or worm medicinals to dredge collaterals， so as to providing ideas for clinical treatment.

Surgery is the mainstay of lung cancer treatment options.Traditionally,lobectomy has held its place as the gold standard for treating localized lung cancer,while sublobar resection,including wedge resection and segmentectomy,was primarily considered as an alternative,often reserved for patient ineligible to sustain a radical intervention.However,with the widespread application of computed tomography(CT)to clinical practice,the increasing detection rate of pulmonary ground glass nodules(GGNs)has reshaped this landscape.Ground glass opacity(GGO)in persistent lung nodules is an indicative factor of a favorable prognosis,typically corresponding to pathological changes such as atypical adenomatous hyperplasia(AAH),adenocarcinoma in situ(AIS),or adenocarcinomas predominantly featuring a lepidic growth pattern.A large number of retrospective studies have shown that sublobar resection can achieve satisfactory therapeutic outcomes for such lesions.A series of prospective studies from Japan have confirmed that for early-stage lung cancers dominated by GGOs,sublobar resection is also a viable curative surgical option.The follow-up data showed that there was no statistical difference in the survival status of these patients compared with that of pulmonary lobectomy.This article aims to delve into the role of limited lung resection in the context of lung adenocarcinoma presenting with GGO features.

Objective To develop an automatic segmentation model of acute stroke lesions based on DWI images,and build a 1-year recurrence prediction model of acute stroke based on this model and machine learning technology.Methods The patients with acute ischemic stroke who received intravascular therapy in Nanjing First Hospital from January 2019 to September 2021 were retrospectively included.The patients were divided into recurrence group and non-recurrence group according to clinical and imaging data within 1 year.The developed EfficientNet-B0 network was applied to segment acute stroke lesions on DWI images and its segmentation efficiency was evaluated.Based on automatic segmentation and manual delineation of tags respectively,the radiomics were extracted and the support vector machine classifier was used to construct the prediction model of acute stroke recurrence.Delong test was used to compare the differences between the two models.Results A total of 268 patients were included in the study,161 in the non-recurrence group and 107 in the recurrence group.The sensitivity,specificity,accuracy and Dice similarity coefficient of DWI automatic lesion segmentation model was 0.791,0.999,0.817 and 0.803,respectively.The area under the curve(AUC)of the prediction model of acute stroke recurrence based on the radiomics of the automatic segmentation lesions was 0.878(95%CI:0.834-0.923)(sensitivity:0.879,specificity:0.851).The AUC of the prediction model of acute stroke recurrence based on the radiomics of of manually outlined tags was 0.865(95%CI:0.819-0.911)(sensitivity:0.860,specificity:0.832).There was no significant statistical difference between the two models(Z=0.526,P=0.599).Conclusion The network proposed in this study can well segment acute stroke lesions on DWI,and the prediction model based on the radiomics of this model can predict the recurrence of acute stroke very well.

Total mesorectal excision (TME) is the gold standard for the treatment of middle and low rectal tumors. Since the first patient who underwent transanal total mesorectal excision (taTME) was reported in 2010, taTME has attracted wide attention from scholars at home and abroad. Fecal incontinence is one of the common complications after taTME, which severely affects the postoperative quality of life of patients. This paper systematically summarizes the commonly used assessment methods, current situation, influencing factors, treatment and nursing progress of postoperative fecal incontinence patients with taTME, in order to provide evidence for improving the quality of life of postoperative defecation incontinence patients with taTME.

(4) Analysis of influencing factors for positive circumferential margin in surgical specimen of intersphincteric resection for rectal cancer. Results of univariate analysis showed that preoperative T staging on preoperative pelvic MRI, mesorectal fascia invasion, extramural venous invasion, pathological T staging, and pathological N staging were related factors for positive circumferential margin in surgical specimen of intersphincteric resection for rectal cancer ( P<0.05). Conclusions:Intersph-incteric resection with transabdominal transanal mixed approach has good specimen quality and low positive rate of surgical margin. T staging on preoperative pelvic MRI may be related to positive circumferential margin after intersphincteric resection for rectal cancer.

Objective:To investigate the application value of transanal endoscopic intersphincteric resection (taE-ISR) in sphincter preservation for low rectal cancer.Methods:The pro-pensity score matching and retrospective cohort study was conducted. The clinicopathological data of 278 patients with low rectal cancer who were admitted to 5 medical centers, including Ruijin Hospital of Shanghai Jiaotong University School of Medicine et al, from January 2017 to December 2021 were collected. There were 178 males and 100 females, aged 58 (range, 49-64)years. Of 278 pati-ents, 147 cases undergoing taE-ISR were divided into the taE-ISR group, and 131 cases undergoing intersphincteric resection (ISR) were divided into the ISR group. Observation indicators:(1) propen-sity score matching and comparison of general data of patients between the two groups after matching; (2) comparison of intraoperative and postoperative conditions between the two groups; (3) long-term follow-up of the two groups; (4) analysis of risk factors affecting sphincter preservation for low rectal cancer. Propensity score matching was done by the 1∶1 nearest neighbor matching method, with a caliper value of 0.05. Propensity score matching analysis was done using the Matching package. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the Student′s t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the Pearson chi-square test or Fisher exact probability. The Kaplan-Meier method was used to calculate survival rate and plot survival curve, and the Log-Rank test was used for survival analysis. Multivariate analysis was conducted using the Logistic regression model with the "glm2" package. The forest plot was used to show the risk factors affecting sphincter preservation for low rectal cancer. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of 278 patients, 180 cases were successfully matched, including 90 cases in the taE-ISR group and 90 cases in the ISR group, respectively. After propensity score matching, the elimination of distance between ischial tuberosities and distance from ischial tuberosity to the skin of buttocks confounding bias ensured comparability between the two groups. (2) Comparison of intraoperative and postoperative conditions between the two groups. Cases with positive distal margins, cases with specimen integrity, cases with sphincter preservation were 1, 88, 88 in the taE-ISR group and 8, 78, 74 in the ISR group, showing significant differences between the two groups ( P<0.05). (3) Long-term follow-up of the two groups. The median follow-up time was 4.3(range, 3.8-5.0)years of the taE-ISR group and 4.1(range, 3.4-4.7)years of the ISR group. The overall survival rate, disease-free survival rate and cumulative recurrence rate were 100.0%, 95.6% and 2.2% of the taE-ISR group, versus 98.9%, 87.8% and 10.0% of the ISR group, showing no significant difference in overall survival rate between the two groups ( χ2=0.97, P>0.05) and significant differences in disease-free survival rate and cumulative recurrence rate between the two groups ( χ2=4.05, 5.26, P<0.05). (4) Analysis of risk factors affecting sphincter preservation for low rectal cancer. Results of multivariate analysis showed that taE-ISR, distance from the tumor to the anus, and adjacent organ damage were independent factors affecting sphincter preservation for low rectal cancer ( odds ratio=0.86, 0.88, 1.35, 95% confidence interval as 0.79-0.93, 0.83-0.92, 1.04-1.74, P<0.05). In further analysis, there were significant differences in sphincter preservation and defecatory dysfunction between the 21 cases with neoadjuvant therapy in the taE-ISR group and the 19 cases with neoadjuvant therapy in the ISR group ( P<0.05). Conclusions:The taE-ISR is safe and feasible for patients with low rectal cancer. Compared with ISR, taE-ISR can significantly improve surgical quality, sphincter preservation rate and patient prognosis.

Objective:To evaluate the effect of pre-infusion of hypertonic saline on the postoperative cognitive function in elderly patients.Methods:This was a prospective study. Seventy-six patients of both sexes, aged≥60 yr, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, who underwent elective shoulder arthroscopic surgery under brachial plexus block combined with general anesthesia from June 2022 to January 2023 in our hospital, were selected and divided into 2 groups ( n=38 each) by the random number table method: hypertonic saline group and normal saline group. At 30 min before anesthesia induction, 3% hypertonic saline of 4 ml/kg was intravenously infused in hypertonic saline group, and normal saline 4 ml/kg was intravenously infused in normal saline group. The occurrence of intraoperative cerebral desaturation events was recorded. Venous blood samples were collected at 24 h postoperatively, and the plasma concentrations of interleukin-1beta (IL-1β), IL-6, tumor necrosis factor-alpha and S-100β were measured by enzyme-linked immunosorbent assay, and the expression of neutrophil CD11b was detected by flow cytometry. Rey auditory verbal learning test, trail making test, digit symbol substitution test, and stroop color-word test were performed at 1 day before surgery and 5 days after surgery, and the postoperative cognitive dysfunction was assessed using the Z-score method. Results:Compared with normal saline group, the concentrations of plasma IL-6, tumor necrosis factor-alpha and S-100β and expression of neutrophil CD11b were significantly decreased in hypertonic saline group, and the incidence of cognitive dysfunction and cerebral desaturation events was decreased in hypertonic saline group ( P<0.05). Conclusions:Pre-infusion of hypertonic saline can reduce inflammatory responses and improve postoperative cognitive function in elderly patients.

Objective To investigate the safety and short-term efficacy of π-shaped anastomosis and circular anastomosis(reverse puncture device)in reconstruction of esophagojejunostomy after laparoscopic total gastrectomy.Methods A retrospective study was used to collect the clinical and pathological data of 75 cases of gastric cancer from January 2019 to March 2021.According to the different reconstruction methods of esophagojejunal anastomosis,the patients were divided into a linear cutting obturator group(π-shaped anastomosis group,n = 27)and a circular anastomat anastomosis group(reverse puncture device group,n = 48).The general information of the two groups,operation time,esophagojejunostomy time,intraoperative bleeding volume,number of intraoperative lymph node dissection,intraoperative complications,and postoperative complications were compared and analyzed.Results The operation time and esophagojejunostomy time in the π-shaped anastomosis group were(221.5±8.8)and(34.7±3.7)min,and the reverse puncture device group were and(246.9±5.6)and(47.2±4.6)min,respectively,the differences were statistically significant(t = 15.19,t = 11.81,P＜0.05).There were no statistical significance in the comparison of intraoperative bleeding volume and number of intraoperative lymph node dissection between the two groups(P＞0.05).In the reverse puncture device group,there were two intraoperative complications,including one case of esophageal jejunal anastomosis atresia and one case of anastomosis tear,postoperative complications occurred in 3 cases,postoperative anastomotic stenosis occurred in 2 case,and anastomotic bleeding occurred in 1 case.Conclusion Laparoscopic total esophagojejunostomy with π-shaped anastomosis and reverse puncture device are safe and feasible.In terms of esophagojejunostomy time,π-shaped anastomosis reconstruction time is shorter.When the small intestine diameter is relatively small and it is difficult to extend into the 25 mm stapler,the advantage of π-shaped anastomosis is more obvious.When the tumor is Siewert type Ⅰ and type Ⅱ adenocarcinoma of gastroesophageal junction,which infiltrates into above the dentate line,reverse puncture device method is recommended for reconstruction.
