Eligibility Criteria for Active Ulcerative Pyoderma Gangrenosum in Clinical Trials: A Delphi Consensus on Behalf of the UPGRADE (Understanding Pyoderma Gangrenosum: Review and Assessment of Disease Effects) Group.

At present, there are no standardized guidelines for determining patient eligibility for pyoderma gangrenosum (PG) clinical trials. Thus, we aim to determine which clinical features, histopathological features, or laboratory features should be included in active ulcerative PG clinical trial eligibility criteria for treatment-naïve patients and patients already treated with immunomodulating medications (treatment-exposed patients). This study employed 4 rounds of the Delphi technique. Electronic surveys were administered to 21 international board-certified dermatologists and plastic surgeon PG experts (June 2022-December 2022). Our results demonstrated that for a patient to be eligible for a PG trial, they must meet the following criteria: (i) presence of ulcer(s) with erythematous/violaceous undermining wound borders, (ii) presence of a painful or tender ulcer, (iii) history/presence of rapidly progressing disease, (iv) exclusion of infection and other causes of cutaneous ulceration, (v) biopsy for H&E staining, and (vi) a presence/history of pathergy. These criteria vary in importance for treatment-naïve versus treatment-exposed patients. Given the international cohort, we were unable to facilitate live discussions between rounds. This Delphi consensus study provides a set of specific, standardized eligibility criteria for PG clinical trials, thus addressing one of the main issues hampering progress toward Food and Drug Administration approval of medications for PG.

Experiences of Using Patient Decision Aids for Decisions About Cancer Treatment: A Meta-Aggregation of Qualitative Studies.

BACKGROUND: Inconsistent results have been found regarding the effects of patient decision aids (PtDAs) in supporting patients' decision-making for cancer treatment. OBJECTIVE: This qualitative meta-aggregation presents the experiences of using PtDAs, as perceived by adult patients with cancer, and highlights the components they perceived as important. METHODS: We used the 3-phase process for meta-aggregation suggested by Joanna Briggs Institute to identify published studies with qualitative evidence from CINAHL, Ovid-MEDLINE, APA PsycINFO, and EMBASE databases. The selected studies involved adults with various cancer diagnoses. The phenomenon of interest and the context for this review were people's experiences of using PtDAs for decisions about first-line cancer treatment. RESULTS: A total of 16 studies were included. The authors achieved consensus on 5 synthesized findings about PtDAs: (1) improved understanding of treatment options and patient values and preferences; (2) served as platforms for expressing concerns, obtaining support, and having meaningful conversations with healthcare providers; (3) facilitated active personal and family engagement in decision-making; (4) enabled recall of information and evaluation of satisfaction with decisions; and (5) presented potential structural barriers. CONCLUSIONS: This study used qualitative evidence to demonstrate the usefulness of PtDAs and identify aspects patients with cancer find particularly beneficial. IMPLICATIONS FOR PRACTICE: Nurses play a crucial role in supporting patients and family caregivers throughout the decision-making process for cancer treatment. Patient decision aids that balance complex treatment information with simple language and illustrations or graphs can enhance patients' comprehension. The integration of values clarification exercises into care can further improve patients' decisional outcomes.

Efficacy of radiofrequency ablation combined with ozone therapy under CT guidance in the treatment of lumbar disc herniation / 中国基层医药

Objective:To investigate the efficacy of radiofrequency ablation combined with ozone therapy under CT guidance in the treatment of lumbar disc herniation.Methods:A total of 93 patients with lumbar disc herniation who were admitted to The First Hospital of Jiaxing from January 2019 to May 2022 were included in this study. They were randomly divided into an observation group ( n = 47) and a control group ( n = 46). The control group was treated with radiofrequency ablation and the observation group was treated with radiofrequency ablation combined with ozone therapy. Efficacy was compared between the two groups at 3 months after surgery. The pain was compared between the two groups before and 7 days and 3 months after surgery. Inflammatory factors were compared between the two groups before and 7 days after surgery. The lumbar spine function was compared between the two groups before and 3 months after surgery. Results:At 3 months after surgery, the excellent and good rate in the observation group was significantly higher than that in the control group [89.36% (42/47) vs. 71.74% (33/47), χ2 = 4.63, P < 0.05). At 7 days and 3 months after surgery, Visual Analogue Scale scores in the observation group were (2.91 ± 0.54) points and (1.32 ± 0.31) points, respectively, which were significantly lower than (3.76 ± 0.62) points and (2.08 ± 0.47) points in the control group ( t = 7.06, 9.22, both P < 0.001). At 7 days after surgery, serum interleukin-1β, interleukin-6, and tumor necrosis factor-α in the observation group were (0.24 ± 0.05) μg/L, (18.49 ± 3.47) ng/L, and (97.94 ± 17.43) ng/L, respectively, which were significantly lower than (0.37 ± 0.09) μg/L, (24.31 ± 4.12) ng/L, and (148.87 ± 20.13) ng/L, respectively in the control group ( t = 8.63, 7.37, 13.05, all P < 0.05). At 3 months after surgery, the Japanese Orthopedic Association score in the observation group was significantly higher than that in the control group [(25.68 ± 2.28) points vs. (21.17 ± 3.24) points, t = -7.78, P < 0.001], and the Oswestry Disability Index in the observation group was significantly lower than that in the control group [(9.84 ± 1.43) points vs. (13.46 ± 2.18) points, t = 9.49, P < 0.001]. Conclusion:Radiofrequency ablation combined with ozone therapy under CT guidance is highly effective on lumbar disc herniation. The combined therapy can reduce pain and inflammatory reactions in patients and improve lumbar function.

Research progress on the relationship between lid-wiper epitheliopathy and dry eye / 国际眼科杂志(Guoji Yanke Zazhi)

Lid-wiper epitheliopathy(LWE)refers to the corresponding pathological changes in the palpebral conjunctiva after the skin-mucosa junction area of the palpebral margin, and staining occurs after using dyes such as fluorescein sodium or lissamine green. Current studies suggest that LWE mainly results from the increase of friction between the lid wiper and the ocular surface. The specific mechanism of LWE is not clear, but the common causes include wearing contact lenses, abnormal tear film, blink abnormalities and inflammation. Clinical studies have found that LWE appears when the conventional dry eye index is negative, so the diagnosis of LWE plays an important role in the early diagnosis and treatment of dry eye. However, there are few studies on the correlation between LWE and dry eye in clinical practice. Based on the existing clinical studies, the etiology, pathogenesis, clinical manifestations and treatment of LWE are introduced, and the research progress of LWE and dry eye is reviewed, hoping to provide reference for further investigation and the clinical application of LWE.

Varieties systematization and standards status analysis of fermented Chinese medicine / 中国中药杂志

Fermented Chinese medicine has long been used. Amid the advance for preservation of experience, the connotation of fermented Chinese medicine has been enriched and improved. However, fermented Chinese medicine prescriptions generally contain a lot of medicinals. The fermentation process is complicated and the conventional fermentation conditions fail to be strictly controlled. In addition, the judgment of the fermentation end point is highly subjective. As a result, quality of fermented Chinese medicine is of great difference among regions and unstable. At the moment, the quality standards of fermented Chinese medicine are generally outdated and different among regions, with simple quality control methods and lacking objective safe fermentation-specific evaluation indictors. It is difficult to comprehensively evaluate and control the quality of fermented medicine. These problems have aroused concern in the industry and also affected the clinical application of fermented Chinese medicine. This article summarized and analyzed the application, quality standards, and the modernization of fermentation technology and quality control methods of fermented Chinese medicine and proposed suggestions for improving the quality standards of the medicine, with a view to improving the overall quality of it.

Arsenic speciation and valence / 中国中药杂志

As arsenic widely exists in nature and has been used in the pharmaceutical preparations, the traditional Chinese medicine(TCM) with arsenic include realgar(As_2S_2 or As_4S_4), orpiment(As_2S_3), and white arsenic(As_2O_3). Among the above representative medicine, the TCM compound formulas with realgar are utilized extensively. Just in Chinese Pharmacopoeia(2020 edition), there are 37 Chinese patent medicines including realgar. The traditional element analysis focuses on the detection of the total amount of elements, which neglects the study on the speciation and valence of elements. The activity, toxicity, bioavailability, and metabolic pathways of arsenic in vivo are closely related to the existence of its form, and different forms of arsenic have different effects on organisms. Therefore, the study on the speciation and valence of arsenic is of great importance for arsenic-containing TCMs and their compound formulas. This paper reviewed four aspects of the speciation and valence of arsenic, including property, absorption and metabolism, toxicity, and analytical assay.

Preparation and evaluation of sirolimus sustained release tablets based on mesoporous silicon loaded self-microemulsion / 药学学报

Sirolimus self-microemulsion-mesoporous silicon sustained release tablets were prepared in order to improve the dissolution of the insoluble drug sirolimus and reduce its side effects. Firstly, sirolimus self-microemulsion was prepared and cured with mesoporous silicon. Secondly, the suitable excipients were selected according to the appearance, hardness and in vitro release rate. The sustained-release tablets with hydroxypropyl methylcellulose (HPMC) as skeleton material were prepared by powder direct pressing method, and the formulation was optimized by central composite design-response surface method to investigate the drug release in vitro. Finally, the pharmacokinetics was carried out in beagle dogs using the commercial sirolimus tablets as references. The final formulation of sustained-release tablets is as follows: 162 mg of sirolimus self-microemulsion-mesoporous silica (1∶1, w/w), 80 mg of HPMC K4M and 80 mg of carboxymethyl starch sodium, the microcrystalline cellulose is 168 mg. The results of in vitro release test showed that the self-made sustained-release tablets released slowly within 12 h, which conformed to the Ritger-Peppas model. The in vivo test results showed that compared with the commercial sirolimus tablets, the Cmax of the sustained-release tablets decreased by 49.47%, the Tmax of the sustained-release tablets was prolonged by 5.1 times, and the relative bioavailability was 105.81%. Sirolimus self-microemulsion-mesoporous silicon sustained-release tablets have good sustained-release effects in vitro and in vivo, which provides a reference for the solubilization of other insoluble drugs and the research and development of sustained-release preparations. Animal experiments and welfare processes were reviewed and approved by the Animal Ethics Committee of the 900TH Hospital of the Joint Logistics support Force.

SRT1720 as an SIRT1 activator for alleviating paraquat-induced models of Parkinson's disease.

Epidemiological studies have linked herbicides and Parkinson's disease (PD), with the strongest associations resulting from long exposure durations. Paraquat (PQ), an herbicide, induces PD-like syndromes and has widely been accepted as a PD mimetic. Currently, there is still no cure to prevent the progression of PD, and the search for effective therapeutic ways is urgent. Recently, the impairing activity of sirtuins (SIRTs), such as SIRT1, may correlate with PD etiology. However, the nonspecificity of SIRT1 agonists has made the protective mechanisms against PD unclear and hampered the therapeutic application of SIRT1. Thus, this study investigated the protective mechanism and therapeutic potential of SRT1720, a more specific agonist for SIRT1 synthesized by Sirtris, in alleviating the toxicity of PQ-induced cellular and animal models of PD. Here we show that SRT1720 alleviates PQ-induced toxicity in cell and animal models. Genetic silencing and pharmacological inhibition of SIRT1 attenuated SRT1720's protection against PQ-induced toxicity. Moreover, SRT1720 not only attenuated PQ-induced increased oxidative stress and mitochondrial free radical formations but also decreased mitochondrial membrane potential. Furthermore, SRT1720 reversed PQ-induced decreased PGC-1α levels and mitochondrial biogenesis. Although PQ and SRT1720 elevated NRF2 and antioxidative enzyme levels, only PQ decreased antioxidative enzyme activity but not SRT1720. NRF2 and PGC-1α silencing attenuated SRT1720 protection against PQ-induced toxicity. SRT1720 targeted SIRT1 and activated downstream PGC-1α and NRF2 signalings to prevent PQ-induced toxicity involving oxidative stress and mitochondrial dysfunction. Thus, SRT1720 might have therapeutic potential in preventing PD.

Effects of different environmental intervention durations on the intestinal mucosal barrier and the brain-gut axis in rats with colorectal cancer.

An enriched environment (EE) is a promising strategy for protecting the intestinal mucosal barrier and regulating the brain-gut axis, but the optimal EE intervention duration is unknown. Here, different EE intervention durations were applied to assess the optimal intervention duration in rats with colorectal cancer. We used a rat model of 1, 2-dimethylhydrazine-induced colorectal cancer. The rats were housed in an EE for 0, 2, 4, 8 weeks and 8-week blank group. The intestinal mucosa and serum TNF-α, IL-6, IL-10, ATP, CRF, and occludin levels and bacterial translocation (BT) were measured, and the intestinal mucosa morphology was evaluated. In 8 weeks, the effect of tumor on intestinal mucosal barrier was not obvious and the EE had a greater impact on it. Eight weeks of EE was more beneficial to the intestinal mucosal mechanical barrier than 2 or 4 weeks of intervention. A significant difference in BT was found between the 4- and 8-week groups. Overall, the analysis of inflammatory factor regulation revealed that the two blank groups exhibited the worst effect, and the intervention effect at 8 weeks was better than that at 2 and 4 weeks. CRF at 4 weeks was higher than that at 8-week blank group. The effect of 8-week intervention duration on the intestinal mucosal barrier was generally better than that of 2- and 4-week durations and intervention within 4 weeks can help to stabilize and promote the secretion of brain gut peptide, but the effect of different intervention durations on the brain-gut peptide levels was not obvious. In the future, we can further explore the molecular biological mechanism of the effect of different EE intervention durations on the intestinal mucosal barrier and analyze the effect of an EE on other brain-gut peptides.

Inhibition of COX-2 ameliorates murine liver schistosomiasis japonica through splenic cellular immunoregulation.

BACKGROUND: We have reported the positive association of the cyclooxygenase 2 (COX-2)/prostaglandin E2 (PGE2) axis with liver fibrosis induced by Schistosoma japonicum (Sj) infection, and TLR4 signaling controlled this axis. However, how COX-2 regulates immune response during Sj infection is still unclear. METHODS: Hematoxylin and eosin staining was used to evaluate the effect of the COX-2-specific inhibitor NS398 on liver granulomatous inflammation and fibrosis. Flow cytometry was used to explore the frequency and amount of different immune cell infiltration in the spleen during Sj infection. RESULTS: NS398 significantly reduced the size of liver granuloma, spleen, and mesenteric lymph node (MLN) and alleviated chronic granulomatous inflammation. Mechanically, this might be by decreasing the number of Sj-induced macrophages and T helper type 1 (Th1), Th2, T follicular helper (Tfh), T follicular regulatory (Tfr), and germinal center B (GC B) cells. There were no differences in the number of neutrophils, myeloid-derived suppressor cells, Th17 cells, regulatory T cells (Treg), or total B cells in the spleen of the mice with or without NS398 treatment. CONCLUSIONS: COX-2/PGE2 inhibition may represent a potential therapeutic approach for schistosomiasis japonica through splenic cellular immunoregulation.

Effects of Cognitive Training and Social Support on Cancer-Related Fatigue and Quality of Life in Colorectal Cancer Survivors: A Systematic Review and Meta-Analysis.

BACKGROUND: Few studies have evaluated the effects of cognitive training and social support on cancer-related fatigue and quality of life. We performed a meta-analysis of randomized controlled trials to examine the efficacy of cognitive training and social support in colorectal cancer patients and survivors. METHODS: The PubMed, Ovid, EMBASE, Cochrane Central Register of Controlled Trials, and China National Knowledge Infrastructure databases were searched from database establishment until August 2021 to identify suitable studies according to relevant key words, taking cancer-related fatigue and quality of life as the outcomes. The Jadad scale was used to evaluate the methodological quality of the studies. Stata 15.1 software was used for statistical analyses, and sensitivity analyses were performed. RESULTS: Eleven studies (6 published in English and 5 published in Chinese) involving 980 patients and survivors were included in the meta-analysis. All studies had Jadad scores ≥3. Statistically significant effects of cognitive training and social support were detected for cancer-related fatigue within 14 weeks (SMD = -1.13, P < .001) and after 14 weeks (SMD = -0.56, P < .001), overall quality of life within 14 weeks (SMD = 0.73, P < .001) and after 14 weeks (SMD = 0.54, P = .003). However, no statistically significant effects of the combination intervention were detected on long-term QOL (SMD = 0.50, P = .435). CONCLUSIONS: Distinct cognitive interventions and a combination of cognitive and social support interventions can help to alleviate long-term and short-term CRF and short-term QOL. Further studies are needed to examine the mechanisms of cognitive training and social support for cancer-related fatigue and overall quality of life in patients and survivors with colorectal cancer.

Effects of sleep interventions on cancer-related fatigue and quality of life in cancer patients: a systematic review and meta-analysis.

BACKGROUND: Nondrug treatments are potentially beneficial for cancer patients. However, the effect of sleep on cancer-related fatigue (CRF) and quality of life (QOL) in cancer patients remains unclear. We conducted a meta-analysis of randomized controlled trials to examine the efficacy of sleep in cancer patients undergoing treatment. METHODS: The PubMed, Ovid, Embase, Cochrane Central Register of Controlled Trials, and China National Knowledge Infrastructure databases were searched to identify suitable studies. Stata 15.0 software was used for statistical analyses. Sensitivity analyses were conducted. Fourteen studies (6 in English and 8 in Chinese) involving 1151 patients were included in the meta-analysis. Ten, five, and six studies that assessed the effects of sleep on CRF, QOL, and quality of sleep, respectively, in cancer patients undergoing treatment were identified. RESULTS: Sleep interventions significantly affected overall CRF (standardized mean difference (SMD) = -1.52, P < 0.01), overall QOL (SMD = 1.20, P < 0.01), physical fatigue (SMD = -0.66, P < 0.01), cognitive fatigue (SMD = -0.38, P = 0.015), and physical function (SMD = 0.64, P < 0.01). Comprehensive intervention measures focusing on sleep, sleep nondrug interventions, and interventions for ≥3 or <3 months affect CRF. However, no significant effects on emotional fatigue, emotional function, perpetual fatigue, depression, or quality of sleep were observed. CONCLUSIONS: Comprehensive interventions focusing on sleep are helpful for CRF. Sleep interventions may only affect physiological function and have no effect on emotional function, perpetual function, or sleep quality. Future research should focus on how to combine sleep interventions with psychological, social, cognitive, and emotional interventions and provide targeted comprehensive nursing measures to better improve CRF, sleep quality, and QOL.

Methods Totally 405 samples (178 males, 227 females) of Kazakh in Tacheng, Xinjiang, were investigated for the types of tongue movement. Chi-square test, u test and cluster analysis were used to explore the characteristics of tongue movement of Kazakhs and the tongue movement of other ethnic groups relation. Generalized multivariate dimension reduction (GMDR) analysis and logistic regression were used to analyze the correlations between tongue movements. Results The frequencies of rolling tongue, folding tongue, twisting tongue, and pointed tongue were 73. 08%, 41. 97%, 18. 02%, and 66. 91% respectively. No gender difference was found in the frequencies of four tongue moving types. Compared with other ethnic groups in our country, the frequency of rolling tongue and pointed tongue was at a moderate level, the frequency of folding tongue was higher, and the frequency of twisting tongue was lower. The cluster analysis result showed that the tongue movement type of Xinjiang Kazak was closest to that of Han nationality in Jinzhou, Liaoning. GMDR result showed that among the four tongue movements, there were interactions between the combinations of rolling tongue and folding tongue, folding tongue and rolling tongue and pointed tongue, twisting tongue and pointed tongue, and rolling tongue and folding tongue,and pointed tongue and folding tongue. Logistic regression result showed that there were correlations between rolling tongue and folding tongue, pointed tongue and folding tongue, folding tongue and pointed tongue and rolling tongue. Conclusion Compared with the tongue movements of the domestic ethnic groups, the four types of tongue movements of the Kazakhs in Xinjiang are stronger in folding tongue movement, weaker in tongue turning movement, and average in rolling tongue and pointed tongue movement. There is a relationship between rolling tongue and folding tongue, pointed tongue and folding tongue, and folding tongue are related to pointed tongue and rolling tongue.

Analysis of Zuojinwan Based on Ancient Literature / 中国实验方剂学杂志

Zuojinwan originated from Danxi′s Experiential Therapy （《丹溪心法》） in the Yuan dynasty. It is a representative prescription for the treatment of liver fire invading stomach syndrome， and is also one of the typical prescriptions of the anti-adjuvant method of traditional Chinese medicine （TCM）. In this paper， the method of bibliometrics was used to systematically sort out the ancient books of Zuojinwan， and 729 relevant literature data were obtained. After certain retrieval and screening， 57 ancient books of TCM were finally obtained. The statistics and analysis were carried out from the aspects of prescription source， historical evolution， composition， functions， evolution of prescription meaning， prescription dose， and preparation and usage of Zuojinwan. It was found that Zuojinwan was composed of Coptis chinensis rhizoma and Euodia rutaecarpa fructus in a ratio of 6∶1. It was mainly used for the treatment of liver fire invading stomach syndrome. The symptoms included pain in chest and hypochondrium， vomiting and bitter mouth， noisy acid-swallowing， red tongue coating yellow， and pulse string number. Later medical records recorded that Zuojinwan was mostly consistent with the original prescription. It mainly treated various diseases caused by liver fire， including left by liver fire， including left hypochondriac pain， swallowing acid and vomiting acid， tendon hernia and lump， epigastric pain， bitter mouth pulse string， head pain， diarrhea， gonorrhea， cold and hot， abdominal pain， alcohol wet yellowing， silence of oral dysentery and so on. There was little controversy in the analysis of relevant prescriptions. In the past dynasties， pills was mainly used， which was consistent with the original prescription. In modern times， it is mainly water flooding for pills or steamed cakes for pills， warm boiling water to serve 6 g， taking 2-3 g per time， the history is basically the same. In this paper， through the excavation， collation and systematic analysis of the ancient literature of TCM that recorded Zuojinwan， we hope to provide the literature basis for the development， inheritance and utilization of this famous classical formulas.

Expression and role of the TRPC family in TGF-β1-induced calcium influx in podocytes / 生理学报

The TRPC family consists of multiple important cationic channels in mammals that participate in a variety of physiological and pathological processes. Our previous studies have shown that transforming growth factor-β1 (TGF-β1) increases the expression of TRPC6 in podocytes, but the roles of other members of the TRPC family in podocytes require further investigation. In this study, we investigated the effect of TGF-β1 on the expression of the TRPC family and the role of the TRPC family in the changes of the intracellular Ca2+ concentration ([Ca2+]i) in podocytes induced by TGF-β1. The model of podocyte injury was established by treatment with TGF-β1 in immortalized glomerular podocytes (MPC5) in vitro. qRT-PCR and Western blot were used to detect the effect of TGF-β1 on the mRNA and protein expression of each TRPC family member. After the expression of each TRPC family member was knocked down by a siRNA-based approach and blocked by SKF96365, respectively, free cytosolic Ca2+ was measured using the fluorescent Ca2+ indicator Fluo-3/AM, and the dynamic change of [Ca2+]i in podocytes was detected by a dynamic high-speed calcium imaging system. The results showed that TGF-β1 increased the protein expression of TRPC1/3/6 in podocytes, but had no effects on the protein expression of TRPC4. The protein expression levels of TRPC5/7 were only affected by 4 ng/mL and 8 ng/mL TGF-β1, respectively. TGF-β1 increased TRPC1/3/6 mRNA levels in podocytes, however had no effects on TRPC4/5/7 mRNA. TGF-β1 significantly increased [Ca2+]i in podocytes. Knockdown of TRPC1/4/5/7 in podocytes had no significant effect on the [Ca2+]i induced by TGF-β1, but TRPC3/6 knockdown significantly decreased the [Ca2+]i. There was no significant difference in the [Ca2+]i between the TRPC6 siRNA-treated group and SKF96365-treated group, but the [Ca2+]i of the TRPC3 siRNA-treated group was significantly higher than that of SKF96365-treated group. These results demonstrate that TGF-β1 increases the expression of the TRPC1/3/6 in podocytes. TGF-β1 increases [Ca2+]i in podocytes, which is dependent on the TRPC3/6 expression. Our results also suggest that the effect of TRPC6 on [Ca2+]i in podocytes may be greater than that of TRPC3.

20 cases of robotic assisted thoracoscopic surgery for the treatment of pulmonary sequestration in children / 中华胸心血管外科杂志

Objective:To analyze the application of robot-assisted thoracoscopic surgery in the treatment of pulmonary sequestration in children.Methods:The clinical data of 20 children with pulmonary sequestration admitted to the Children's Hospital Zhejiang University School of Medicine from May to November 2020 were analyzed retrospectively. There were 13 males and 7 females, ages ranged from 6 months to 5 years old, with median age of 10 months. Body weight ranged from 7.5 to 18.0 kg, with mean weight of(9.95±2.46)kg. Abnormal blood supply vessels in pulmonary sequestration were found by chest enhanced CT and were further confirmed during surgery. All the other 19 cases were found to have pulmonary lesions by prenatal ultrasound except 1 case due to repeated infection. The lesions were located in left lung in 15 cases and right lung in 5 cases.Results:1 case was converted to thoracotomy due to failure of intraoperative single lung ventilation and inability of artificial pneumothorax to collapse the lung lobe, and other 19 cases were successfully completed by robot-assisted thoracoscopic surgery. The operation time ranged from 40 to 270 min, mean(88.25±55.68) min. All 10 patients with extralobar sequestration underwent simple pneumonectomy, including 2 patients with intra-diaphragmatic pulmonary sequestration. In 10 cases of intralobar sequestration, 2 cases underwent wedge resection, 2 cases underwent segmental resection, and 6 cases underwent lobectomy. No operative death occurred. The postoperative hospital time ranged from 3 to 10 days, mean(5.00±1.89) days. All patients recovered well and no complications such as pleural effusion and atelectasis were observed during 1-6 months follow-up.Conclusion:The robotic surgical system is safe and effective for the treatment of pulmonary sequestration in children.
