Endoscopic thoracic sympathicotomy/sympathotomy (ETS) is the first-line treatment for palmar hyperhidrosis with best minimally invasive effect. In recent years, with the widespread development of ETS in the treatment of palmar hyperhidrosis, many medical centers list ETS surgery as the day surgery. Nevertheless, there is no expert consensus on medical quality control of day surgery for ETS yet. Therefore, the Chinese Medical Doctor Association Thoracic Surgeons Branch Hyperhidrosis Subcommittee, Sympathetic Neurosurgery Expert Committee of WU Jieping Medical Foundation, and Fujian Provincial Strait Medical and Health Exchange Association Hyperhidrosis Special Committee organized domestic experts to conduct repeated consultations and sufficient discussions based on domestic and foreign literatures, to formulate the "Chinese expert consensus on ETS optimization and surgical quality control of day surgery for palmar hyperhidrosis". It aims to provide a reference for the clinical diagnosis and treatment of palmar hyperhidrosis for thoracic surgery colleagues in our country, to enhance their management level and work efficiency, and ultimately to achieve standardized quality control.

BACKGROUND: Durvalumab after chemoradiotherapy (CRT) failed to bring survival benefits to patients with epidermal growth factor receptor ( EGFR ) mutations in PACIFIC study (evaluating durvalumab in patients with stage III, unresectable NSCLC who did not have disease progression after concurrent chemoradiotherapy). We aimed to explore whether locally advanced inoperable patients with EGFR mutations benefit from tyrosine kinase inhibitors (TKIs) and the optimal treatment regimen. METHODS: We searched the PubMed, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases from inception to December 31, 2022 and performed a meta-analysis based on a Bayesian framework, with progression-free survival (PFS) and overall survival (OS) as the primary endpoints. RESULTS: A total of 1156 patients were identified in 16 studies that included 6 treatment measures, including CRT, CRT followed by durvalumab (CRT-Durva), TKI monotherapy, radiotherapy combined with TKI (RT-TKI), CRT combined with TKI (CRT-TKI), and TKI combined with durvalumab (TKI-Durva). The PFS of patients treated with TKI-containing regimens was significantly longer than that of patients treated with TKI-free regimens (hazard ratio [HR] = 0.37, 95% confidence interval [CI], 0.20-0.66). The PFS of TKI monotherapy was significantly longer than that of CRT (HR = 0.66, 95% CI, 0.50-0.87) but shorter than RT-TKI (HR = 1.78, 95% CI, 1.17-2.67). Furthermore, the PFS of RT-TKI or CRT-TKI were both significantly longer than that of CRT or CRT-Durva. RT-TKI ranked first in the Bayesian ranking, with the longest OS (60.8 months, 95% CI = 37.2-84.3 months) and the longest PFS (21.5 months, 95% CI, 15.4-27.5 months) in integrated analysis. CONCLUSIONS: For unresectable stage III EGFR mutant NSCLC, RT and TKI are both essential. Based on the current evidence, RT-TKI brings a superior survival advantage, while CRT-TKI needs further estimation. Large randomized clinical trials are urgently needed to explore the appropriate application sequences of TKI, radiotherapy, and chemotherapy.

Objective:To investigate the clinical situation of 201 emergency adult sudden death patients, and analyze the influence of white blood cell count and arterial blood lactate level on prognosis.Methods:The clinical data of 201 patients diagnosed with sudden death in the emergency department of Medical College of Cangzhou people's Hospital from January 2017 to January 2021 were retrospectively analyzed. The gender, age, disease composition and etiology of the patients were statistically analyzed. The independent sample t-test was used to compare the measurement data with normal distribution, the χ 2 test or Fisher exact probability method was used to compare the counting data between groups, and the logistic regression model was used to screen the risk factors of emergency death, and the impact of white blood cell count and arterial blood lactate level on the prognosis was analyzed. Results:After active rescue, 11.44% (23/201) of the patients were successfully rescued, and 88.56% (178/201) of the patients were ineffective; ≥46-≤65 years old was the age group with high incidence of sudden death (55.22%(111/201)). The proportion of male (43.28% (87/201), 23.38% (42/201)) in the age group of ≥46-≤65 years old and the age group over 65 years old were higher than that of female (11.94% (24/201), 14.43% (29/201)), with a statistically significant difference (χ 2=4.801, 9.209; P=0.028, 0.002). In the past history of sudden death patients, the proportion of cardiovascular disease (53.23% (107/201)) was the highest; the proportion of patients may have inducements before sudden death was 74.13% (149/201), the proportion of patients have premonitory symptoms before sudden death was 67.66% (136/201), and sudden cardiac death was the first cause. Logistic regression analysis showed that white blood cell count ( OR=4.442,95% CI: 1.898-10.395), arterial blood lactic acid concentration ( OR=4.272,95% CI: 2.024-9.016), and albumin concentration ( OR=2.657,95% CI: 1.302-5.422) were independent risk factors affecting emergency sudden death patients ( P values were 0.001, <0.001, 0.007, respectively). Conclusions:There are some differences in gender, age and past history of adult sudden death patients. Most of them have premonitory symptoms and inducements. Sudden cardiac death is the primary cause. The increases of white blood cell count and lactic acid level, the decrease of albumin level are the risk factors of sudden death.

Primary palmar hyperhidrosis (PPH) is a pathologic condition of excessive sweating on hands that has adverse impacts on patients' social activity, professional life, and psychological state. Endoscopic thoracic sympathicotomy (ETS) is by far the treatment choice for PPH with the most stable and durable curative effects, but special attention should be given to the side effects of the surgery, especially compensatory hyperhidrosis (CH). This consensus is the second version of the Chinese Expert Consensus on the Surgical Treatment of PPH by the China Expert Committee on Palmar Hyperhidrosis (CECPH), which was published 10 years ago. This consensus emphasizes the need for special attention and careful assessment of the patients’ feelings, as well as their emotional and mental state, and emphasizes that distress due to palmar sweating and the desire for treatment are prerequisites for diagnosis. It also provides a more nuanced delineation of CH and reviews all new attempts to prevent and treat this side effect. New evidence of the epidemiology, pathogenesis of PPH, and indications for surgery were also assessed or recommended.

Objective:To investigate the anatomical variation of the T3 sympathetic ganglia and its relationship with surgical outcomes in primary palmar hyperhidrosis.Methods:A total of 86 patients with primary palmar hyperhidrosiswho underwent R4 sympathicotomy from November 2017 to September 2018 were prospectively enrolled. The anatomical variation of T3 sympathetic ganglia was observed by fluorescence thoracoscopy. The therapeutic effect and side effect were followed up after operation.The relationship between T3 anatomical variation and postoperative effect was analyzed.Results:82.6% of T3 ganglion had no anatomic variation, 17.4% of T3 ganglion shifted down to the surface of the fourth rib or intercostal space. After 1 month of follow-up, the therapeutic effect was: overly dry 2.1%, dry 39.4%, mild moist 57.0%, moist 1.4% innormalside, and 13.3%, 53.3%, 33.3%, 0 in the variation side respectively. Mann- Whitney U test showed statistically significant difference between the two groups( P=0.004). After 1 year of follow-up, the effect was 0, 36.5%, 56.9%, 6.6% in normal side, and 0, 33.3%, 63.0%, 3.7% in the variation side respectively. There was no significant difference between the two groups by Mann- Whitney U test( P=0.869). Conclusion:Fluorescence thoracoscopy showed that the variation rate of the position of T3 sympathetic ganglion was 17.4%. Postoperatively, patients with the downshift variation of T3 sympathetic ganglion have drier hands in short-term follow-up.

Objective:To preliminarily evaluate the effect of tension stimulation on the biological activity of and expression of fibrosis marker genes in keloid fibroblasts (KD-Fbs) .Methods:Three patients who were diagnosed with keloids and received surgical treatment were collected from the Department of Dermatology, Tangdu Hospital, the Fourth Military Medical University from January to March 2017. Human KD-Fbs were isolated from resected keloid tissues, and subjected to primary culture. The third- to sixth-passage KD-Fbs were divided into tension group and control group to be cultured in the tension-based chamber and control chamber respectively, and subjected to tension stimulation and normal culture respectively. Cell counting kit-8 (CCK8) assay was performed to assess the proliferative activity of KD-Fbs after 1-, 2-, 3- and 4-day culture, and the scratch assay to evaluate the migratory ability of KD-Fbs after 1- and 2-day culture. After 48-hour treatment, real-time quantitative PCR and Western blot analysis were performed to determine the mRNA and protein expression of fibrosis markers type Ⅰ collagen, fibronectin and α-smooth muscle actin (α-SMA) in KD-Fbs respectively. Two-independent-sample t test was used for comparisons between 2 groups. Results:CCK8 assay showed that the proliferative activity of KD-Fbs was significantly higher in the tension group than in the control group after 1-, 2-, 3- and 4-day culture ( t=3.05, 7.00, 16.65, 15.19, respectively, all P< 0.05) . After 1- and 2-day culture, the scratch assay showed that the migration rate of KD-Fbs was significantly higher in the tension group (48.65%±3.96%, 100.00%, respectively) than in the control group (9.36%±1.14%, 50.35%±4.23%, t=16.53, 20.35, respectively, both P< 0.01) . Real-time quantitative PCR showed that the mRNA expression of type Ⅰ collagen, fibronectin and α-SMA was significantly higher in the tension group (3.04±0.20, 2.16±0.10, 3.76±0.24, respectively) than in the control group (1.00; t=17.57, 21.01, 20.25, respectively, all P< 0.01) . As Western blot analysis revealed, changes in the protein expression of the 3 fibrosis markers were consistent with their mRNA expression changes (all P< 0.05) . Conclusion:Tension may participate in the fibrosis in keloids by promoting the expression of fibrosis marker genes, and enhancing the proliferative and migratory ability of KD-Fbs.

This guideline systematically reviewed and summarized the 20 years' clinical and basic research experience of minimally invasive treatment of palmar hyperhidrosis (PH) in China, and discussed the hot and difficult issues of minimally invasive treatment of PH. We have formed a new consensus of PH in terms of its definition, clinical manifestations, diagnostic criteria and classification, surgical indications and contraindications, surgical procedures and management of complications, especially in the area of postoperative compensatory hyperhidrosis (CH). This guideline confirmed that endoscopic thoracic sympathicotomy (ETS) was the most effective treatment for PH and that CH was the most common side effect. In order to reduce the incidence of CH, eliminate patient's distress and improve patient's satisfaction, the guideline emphasized that the keys to prevent CH were to pay attention to pre-operative interview, communicate with patients, select patients carefully, avoid the enlargement of operative indication and optimize operative procedure. This guideline also introduced the advantages and disadvantages of various methods to reduce the incidence of CH. We provided this authoritative guidance document in order to avoid the surgical risk, strengthen the perioperative management and improve the sugery effect.

Objective To explore the relationship between iodine and fluoride content in drinking water and the incidence of adult thyroid nodules in Cangzhou,Hebei.Methods According to the previous reports on iodine and fluoride levels in drinking water in Cangzhou,from November 2016 to January 2017,Cangzhou was divided into high iodine,low iodine,normal iodine and fluorine,low iodine and high fluorine,high iodine and high fluorine areas,and according to the different contents of iodine and fluorine in drinking water,high iodine and high fluorine area was further divided into high iodine and high fluorine 1 (iodine:743.30 μg/L,fluorine:4.27 mg/L),2 (iodine:119.31μg/L,fluorine:4.67 mg/L) and 3 (iodine:105.30 μg/L,fluorine:1.64 mg/L) subareas.Subjects who lived for 20 or more years and aged 30 or older,without serious disease and not taken iodized salt were selected.Palpation was used to examine the size,texture,mass,tenderness and mobility of the thyroid gland.The boundary,internal echo,blood flow and quantity of nodules were observed and recorded by color Doppler.Results The prevalence difference of thyroid nodules [36.8％ (629/1 710),32.8％ (636/1 938),25.1％ (427/1 700)] in high iodine,low iodine and normal iodine and fluorine areas was statistically significant (x2 =55.597,P ＜ 0.05).The prevalences of thyroid nodules in both high iodine and low iodine areas were higher than that of normal iodine and fluorine area (P＜ 0.016 7).The prevalence difference of thyroid nodules [43.3％ (749/1 730),39.8％ (712/1 790),34.9％ (623/1 785)] in high iodine and high fluorine 1,2 and 3 subareas was statistically significant(x2 =26.220,P ＜ 0.05).Compared with low iodine area,the prevalence of thyroid nodules [41.2％ (735/1 785)] in low iodine and high fluorine area was increased (x2 =6.288,P ＜ 0.05).Conclusions Both high iodine and low iodine can induce thyroid nodules.In water source areas with high iodine content,both high iodine and high fluorine are the factors inducing thyroid nodules.The prevalence of thyroid nodules in low iodine and high fluorine area is significantly higher than that of low iodine area.
