ABSTRACT

Objective:To explore the clinical utility of metagenomic next-generation sequencing (mNGS) for patients with critically ill atypical rickettsial infections in the early diagnosis and therapy.Methods:From Jan 2020 to Aug 2022, clinical features, blood biochemical results, imaging data and mNGS results in patients with unexplained critical illnesses were collected and analyzed retrospectively. Fisher's exact test was used to compare the positive rate of mNGS and weil felix reaction.Results:All 15 patients with rickettsial disease had fever, 12 cases had headache, but only 3 had a typical rash or scab of diagnostic significance, 6 had septic shock and all had multi-organ dysfunction; blood mNGS tests were positive in 15 cases, of which 10 had Orientia tsutsugamushi detected in their blood and the remaining five had Rickettsia moschata detected in their blood. The positive rate of mNGS was significantly higher than that of the weil felix reaction (15/15 vs 0, P<0.001). All patients were given doxycycline and other treatments after diagnosis, of which 14 improved and were discharged, and one died 1 week after discharge due to critical condition and abandonment of treatment. Conclusion:mNGS can improve the detection rate of atypical rickettsiae in patients with negative routine test results, which can provide valuable reference basis for early diagnosis and early anti-infection treatment of patients with critical rickettsial disease.

ABSTRACT

AIM: To observe the clinical features of acute macular neuroretinopathy(AMN)induced by Omicron.METHODS: A retrospective study. A total of 9 patients(18 eyes)diagnosed with AMN from December 2022 to January 2023 in the Hospital of Chengdu University of Traditional Chinese Medicine were included. Patients underwent spectral-domain optical coherence tomography(SD-OCT), fundus fluorescein angiography(FFA), fundus photography, autofluorescence(AF), infrared reflectance(IR), optical coherence tomography angiography(OCTA)and multicolor, etc. Furthermore, they were followed up for 1~3mo and observed the prognosis.RESULTS: The initial symptom of the Omicron-induced AMN was the sudden onset of central/paracentral scotoma in the eyes with or without impaired vision and metamorphopsia, and the scotoma could persist for at least 3mo. The image features of AMN are as follows. First, the SD-OCT examination showed the rupture of outer retinal layers, scattered hyperreflective lesions, and atrophy of outer retinal layers. In severe cases, hyperreflective lesions were seen in the inner nuclear layer(INL)or with microcystic cavities under the retinal pigment epithelium(RPE). Second, the OCTA examination demonstrated the decreased blood flow density of the deep capillary plexus(DCP)of the macula. Third, the IR examination showed the weak reflection of lesion areas. Fourth, the fundus photography demonstrated the localized brown wedge-shaped lesion.CONCLUSIONS: The Omicron-induced AMN is mostly found in young females, and the characteristic manifestation of fundus is damage to the outer retinal layers. The extent of fundus lesions is related to the systemic inflammatory response and ocular microcirculatory changes after infection. The multimodal fundus image examination and a history of Omicron infection are helpful to diagnose the Omicron-induced AMN.

ABSTRACT

OBJECTIVE@#To assess the safety and efficacy of"leverage pry-off method"for preventing thermal injury during microwave ablation of benign thyroid nodules.@*METHODS@#From July, 2017 to September, 2019, a total of 348 patients with benign thyroid nodules underwent ultrasound-guided microwave ablation. For protecting from thermal injury during the ablation, "hydrodissection technique" was used in 174 of the patients (admitted from July, 2017 to August, 2018) and "leverage pry-off method" in the other 174 patients (admitted from September, 2018 to September, 2019). All the patients were followed up for 1 to 12 months after the operation for observation of severe complications and nodular residues.@*RESULTS@#Ultrasound-guided microwave ablation was completed in all the 348 patients. The most common severe complication associated with the ablation was voice change, occurring in 3 cases (1.7%) in "hydrodissection technique" group and in 4 (2.3%) in the "leverage pry-off method" group, showing no significant difference between the two groups (P>0.05). During the follow-up, no significant difference was found in the rate of nodular residues between the "hydrodissection technique" group and "hydrodissection technique" group (9.8% vs 10.9% (P>0.05).@*CONCLUSIONS@#The "leverage pry-off method" is simple and effective for preventing thermal injury during microwave ablation of benign thyroid nodules.

ABSTRACT

@#Objective     To investigate the safety of thoracic surgery for high-altitude patients in local medical center. Methods    We retrospectively collected 258 high-altitude patients who received thoracic surgery in West China Hospital, Sichuan University (plain medical center, 54 patients) and People's Hospital of Ganzi Tibetan Autonomous Prefecture (high-altitude medical center, 204 patients) from January 2013 to July 2019. There were 175 males and 83 females with an average age of 43.0±16.8 years. Perioperative indicators, postoperative complications and related risk factors of patients were analyzed. Results    The rate of minimally invasive surgery in the high-altitude medical center was statistically lower than that in the plain medical center (11.8% vs. 55.6%, P<0.001). The surgical proportions of tuberculous empyema (41.2% vs. 1.9%, P<0.001) and pulmonary hydatid (15.2% vs. 0.0%, P=0.002) in the high-altitude medical center were statistically higher than those in the plain medical center. There was no statistical difference in perioperative mortality (0.5% vs. 1.9%, P=0.379) or complication rate within 30 days after operation (7.4% vs. 11.1%, P=0.402) between the high-altitude center and the plain medical center. Univariate and multivariate analyses showed that body mass index≥ 25 kg/m2 (OR=8.647, P<0.001) and esophageal rupture/perforation were independent risk factors for the occurrence of postoperative complications (OR=15.720, P<0.001). Conclusion    Thoracic surgery in the high-altitude medical center is safe and feasible.

ABSTRACT

Objective:To investigate the efficacy and safety of noninvasive high-frequency oscillatory ventilation in the treatment of respiratory failure in premature infants.Methods:Sixty-one premature infants with respiratory failure who received treatment in Neonatal Intensive Care Unit, Wenzhou Central Hospital from June 2019 to June 2020 were included in this study. They were randomly assigned to undergo either noninvasive high-frequency oscillatory ventilation (observation group, n = 31) or transnasal continuous positive airway pressure ventilation (control group, n = 31). Blood gas indicators, including pH value, oxygen partial pressure (PaO 2), partial pressure of carbon dioxide (PaCO 2), oxygenation index (OI), and respiratory index (RI), were determined before ventilation and 2, 8, 12, and 24 hours after ventilation. At the same time, the incidence of complications post-ventilation, including intracranial hemorrhage, bronchopulmonary dysplasia, air leakage, nasal crush injury, retinopathy of prematurity, abdominal distension, and necrotizing enterocolitis, was recorded in each group. Results:There were no significant differences in pH value, PaO 2, PaCO 2, OI, and RI pre-ventilation between observation and control groups ( t = 0.58, 0.64, 0.85, 0.43, 0.70, all P > 0.05). pH value, PaO 2, and OI measured 2, 8, 12 and 24 hours post-ventilation were significantly higher in the observation group than in the control group (pH value: t2 h = 3.20, t8 h = 4.81, t12 h = 6.39, t24 h = 5.22; PaO 2value:t2 h = 5.80, t8 h = 6.31, t12 h = 7.55, t24 h = 6.97; OI value: t2 h = 6.38, t8 h = 8.37, t12 h = 11.30, t24 h = 9.61). PaCO 2 and RI values were significantly lower in the observation group than in the control group (PaCO 2value:t2 h = 4.29, t8 h = 5.09, t12 h = 6.83, t24 h = 8.30; RI value: t2 h = 3.26, t8 h = 5.81, t12 h = 7.36、 t24 h = 6.54) (all P < 0.05). The incidence of complications was significantly lower in the observation group than in the control group [25.81% (8/31) vs. 46.67% (14/30), χ2 = 8.75, P < 0.05]. Conclusion:Compared with transnasal continuous positive airway pressure ventilation, noninvasive high-frequency oscillatory ventilation leads to better ventilation performance and a greater oxygenation ability, exhibits stronger effects on CO 2 clearance and acidosis correction, and has fewer complications in premature infants with respiratory failure. Therefore, noninvasive high-frequency oscillatory ventilation is suitable for clinical application.

ABSTRACT

Objective:To assess the applicability of the Chinese version of the symptom assessment in dry eye (SANDE) questionnaire refer to the ocular surface disease index (OSDI) questionnaire.Methods:A cross-sectional study was conducted.Three hundred and twenty-three students from a senior high school in Hongkou District in Shanghai were enrolled in June 2020.The Chinese version of the SANDE and the OSDI questionnaires were answered by the students to assess the dry eye symptom and were collected on-site.Scores of the two questionnaires were calculated.According to the OSDI score, the students were divided into the normal control group ( n=87), mild dry eye group ( n=82), moderate dry eye group ( n=87) and severe dry eye group ( n=67). Cronbach α was obtained to evaluate the internal consistency.Kruskal-Wallis test was used to analyze the difference in SANDE scores among dry eye groups with different severities and evaluate the discriminative validity.Correlation between the total scores of the two questionnaires was analyzed by using Spearman rank correlation analysis to evaluate the criterion validity.Factor analysis was used to evaluate the construct validity.Receiver operating characteristic curve (ROC) was drawn to obtain the area under the ROC curve (AUC) and cut-off point to evaluate the diagnostic threshold for dry eye.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Shanghai General Hospital (No.2020KY026). Written informed consent was obtained from guardians of each subject. Results:The Cronbach α of the SANDE and OSDI questionnaires were 0.856 and 0.829, respectively.SANDE score of the four groups classified according to the OSDI score was 7.0 (2.5, 16.9) for the normal control group, 17.0 (8.4, 31.0) for the mild dry eye group, 29.2 (14.6, 49.4) for the moderate dry eye group and 49.1 (24.4, 60.7) for the severe dry eye group, respectively, which was increased in turn.There was a statistically significant overall difference in the SANDE score among the four groups ( H=113.213, P<0.001), and statistically significant pairuise differences were found (all at P<0.05). The SANDE score was moderately positively associated with the OSDI score ( rs=0.615, P<0.001). The factor analysis revealed that for the SANDE questionnaire, factor loadings of its two items on the common factors were higher than 0.5, among which the frequency of dry eye symptoms was 0.936, and the severity of dry eye symptoms was 0.936.The AUC of the SANDE questionnaire was 0.815 ( P<0.001, 95% CI: 0.770-0.860). When using 23 as the diagnostic threshold for dry eye, the sensitivity and specificity of the SANDE questionnaire were 60.59% and 88.51%, respectively. Conclusions:The Chinese version of the SANDE questionnaire shows good reliability, validity, discrimination ability and slightly poor sensitivity in detecting dry eye.As a simple assessment questionnaire, it is applicable to the Chinese population and is of good clinical application value.

ABSTRACT

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

ABSTRACT

Aberrant regulation of DNA methylation plays a crucial causative role in haematological malignancies (HMs). Targeted therapy, aiming for DNA methylation, is an effective mainstay of modern medicine; however, many issues remain to be addressed. The progress of epigenetic studies and the proposed theory of "state-target medicine" have provided conditions to form a new treatment paradigm that combines the "body state adjustment" of CM with targeted therapy. We discussed the correlation between Chinese medicine (CM) syndromes/states and DNA methylation in this paper. Additionally, the latest research findings on the intervention and regulation of DNA methylation in HMs, including the core targets, therapy status, CM compounds and active components of the Chinese materia medica were concisely summarized to establish a theoretical foundation of "state-target synchronous conditioning" pattern of integrative medicine for HMs, simultaneously leading a new perspective in clinical diagnosis and therapy.

ABSTRACT

Gastric cancer is one of the most common gastrointestinal malignancies, and the incidence and mortality of gastric cancer remain high in China. In recent years, with the rapid popularization of laparoscopic technology, fluorescent laparoscopic technology is increasingly getting mature, providing a new method for accurate clinical tracing of lymph nodes and prediction of tumor metastasis lymph nodes. A large number of scientific research experiments and clinical trials have shown that, laparoscopic lymph node diagnosis technology based on the fluorescent indocyanine green (ICG) can significantly improve the efficiency of lymphadenectomy and prediction accuracy of lymph node metastasis, and can reveal a more accurate scope of lymphadenectomy in gastric cancer for surgeons, so as to avoid excessive adenectomy as well as iatrogenic injuries on patients. Although the status of the technology in gastric cancer surgery mentioned above continues improving, the overall operation process details of ICG fluorescence imaging, standardized fluorescence detecting equipment, and postoperative pathological examination process still need to be further optimized.

ABSTRACT

The proportion of adenocarcinoma of the esophagogastric junction (AEG) in gastric cancer is gradually increasing. Due to the unique anatomical structure and biological characteristics of the tumor at this site, AEG has a certain degree of complexity in many aspects of diagnosis and treatment, which brings difficulties to the operation method, the selection of the resection range, the lymph node dissection and the treatment decision-making. Therefore, AEG has always been the focus of academic debate. With the development of minimally invasive surgery in recent years, laparoscopic technology has been increasingly mature and widely used in the treatment of gastrointestinal tumors. Compared with distal gastric cancer, the minimally invasive treatment of AEG is in a lagging state, and there are also a series of problems that have not yet reached a consensus. This article reviews and summarizes the recent research progress in two aspects: proximal gastrectomy for AEG and lymph node dissection. Laparoscopic-assisted proximal gastrectomy is safe for early proximal gastric cancer and has a long-term survival outcome not inferior to total gastrectomy, but the surgical indications must be strictly selected. Abdominal lymph node metastasis of AEG is mainly in group 1, 2, 3, and 7, and mediastinal lymph node metastasis is closely related to the length of the infiltrated esophagus. The abdominal transhiatal (TH) approach can obtain a sufficient number of harvested lymph node, and has good safety and efficacy, which is the first-choice of surgical approach for early AEG. The results of the CLASS-10 clinical trial can provide a higher level of evidence for laparoscopic mediastinal lymph node dissection. Laparoscopic surgery for AEG should be carried out in experienced medical center based on clinical research.

ABSTRACT

Teaching quality is directly related to the performance of universities in fostering talents. Being innovative, high-level, and challenging (IHC) is the basic goal of course reform at universities in the new era. It is essential to reform the contents and teaching mode to improve the IHC properties of the existing courses. We first designed the three-dimensional goals of Molecular Biology Experiment teaching and the contents to support these goals. Then, we pinpointed the common points shared by blended teaching and experiment course, and designed the ways of blended teaching for the course. The reformed course contents and teaching mode have enhanced its IHC properties, and achieved good teaching performance. This paper provides a reference for the reform of experiment courses in universities.

ABSTRACT

Repetitive transcranial magnetic stimulation (rTMS) and intermittent theta-burst stimulation (iTBS) are evidenced-based treatments for patients with major depressive disorder (MDD) who fail to respond to standard first-line therapies. However, although various TMS protocols have been proven to be clinically effective, the response rate varies across clinical applications due to the heterogeneity of real-world psychiatric comorbidities, such as generalized anxiety disorder, posttraumatic stress disorder, panic disorder, or substance use disorder, which are often observed in patients with MDD. Therefore, individualized treatment approaches are important to increase treatment response by assigning a given patient to the most optimal TMS treatment protocol based on his or her individual profile. This literature review summarizes different rTMS or TBS protocols that have been applied in researches investigating MDD patients with certain psychiatric comorbidities and discusses biomarkers that may be used to predict rTMS treatment response. Furthermore, we highlight the need for the validation of neuroimaging and electrophysiological biomarkers associated with rTMS treatment responses. Finally, we discuss on which directions future efforts should focus for developing the personalization of the treatment of depression with rTMS or iTBS.

ABSTRACT

@#Objective     To analyze the perioperative outcomes of uniportal thoracoscopic lobectomy compared with three-port thoracoscopic lobectomy. Methods     Data were extracted from the Western China Lung Cancer Database, a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University. Perioperative outcomes of the patients who underwent uniportal or three-port thoracoscopic lobectomy for lung cancer during January 2014 through April 2021 were analyzed by using propensity score matching. Altogether 5 817 lung cancer patients were enrolled who underwent thoracoscopic lobectomy (uniportal: 530 patients; three-port: 5 287 patients). After matching, 529 patients of uniportal and 1 583 patients of three-port were included. There were 529 patients with 320 males and 209 females at median age of 58 (51, 65) years in the uniportal group and 1 583 patients with 915 males and 668 females at median age of 58 (51, 65) years in the three-port group. Results     Uniportal thoracoscopic lobectomy was associated with less intraoperative blood loss (20 mL vs. 30 mL, P<0.001), longer operative time (115 min vs. 105 min, P<0.001) than three-port thoracoscopic lobectomy. No significant difference was found between the two groups regarding the number of lymph node dissected, rate of conversion to thoracotomy, incidence of postoperative complication, postoperative pain score within 3 postoperative days, length of hospital stay, or hospitalization expenses. Conclusion     Uniportal video-assisted thoracoscopic lobectomy is safe and effective, and the overall perioperative outcomes are comparable between uniportal and three-port strategies, although the two groups show differences in intraoperative blood loss.

ABSTRACT

@#Objective     To verify the feasibility and accuracy of the "lung surface intersegmental constant proportion landmarks", developed by our center, in identifying intersegmental planes during pulmonary segmentectomy. Methods    We prospectively enrolled the patients who planned to receive thoracoscopic segmentectomy in West China Hospital of Sichuan University and The Third People's Hospital of Chengdu from September 2021 to October 2021. We took a relatively objective and feasible method, intravenous injection of indocyanine green, in identifying intersegmental planes as standard control. We intraoperatively judged the consistency between "lung surface intersegmental constant proportion landmarks" and intravenous injection of indocyanine green in identifying intersegmental planes. We discerned main landmarks of intersegmental plane by the constant proportion segment module, which was built based on the "lung surface intersegmental constant proportion landmarks", as well as distinguished the planes with discrepant fluorescence by peripheral intravenous indocyanine green injection. When the distance between the landmarks determined by the "ung surface intersegmental constant proportion landmarks" and the segmental boundaries displayed by indocyanine green  fluorescence staining was ≤1 cm, the landmarks were judged to be consistent with the planes with discrepant fluorescence. As long as one of the landmarks was judged to be consistent, the method was considered to be feasible and accurate. Results 聽 聽 A total of 21 patients who underwent thoracoscopic segmentectomy were enrolled, with 5 male and 16 female patients. The median age was 55 years, ranging from 34 to 76 years. A total of 11 patients received left-side surgery, while 10 patients received right-side surgery. In the operations of 21 pulmonary segmentectomies, at least one intersegmental landmark determined by the "lung surface intersegmental constant proportion landmarks" was consistent with the intersegmental plane determined by indocyanine green fluorescence staining in each patient. Conclusion 聽 聽The intersegmental landmarks determined by the "lung surface intersegmental constant proportion landmarks" are consistent with that determined by indocyanine green fluorescence staining. The method of "lung surface intersegmental constant proportion landmarks" is feasible and accurate in identifying intersegmental planes during pulmonary segmentectomy.

ABSTRACT

@#Objective     To summarize the perioperative and long-term outcomes of ground-glass opacity (GGO) dominant early stage lung cancer patients treated by anatomic segmentectomy. Methods     We collected clinical data of 756 patients from Western China Lung Cancer Database, who underwent intentional anatomic segmentectomy [tumor size (T) ≤ 2 cm, GGO ≥ 50%] in the Department of Thoracic Surgery, West China Hospital, Sichuan University from 2009 to 2018. There were 233 males and 523 females at a median age of 53 (25-83) years including 290 (38.4%) patients of simple segmentectomy and 466 (61.6%) patients of complex segmentectomy. All patients were diagnosed as adenocarcinoma, including 338 (44.7%) patients of minimally invasive adenocarcinoma and 418 (55.3%) patients of invasive adenocarcinoma. Results     The median operative time was 115 (38-300) min, the median blood loss was 20 (5-800) mL, 58 (7.7%) patients had postoperative complications and the postoperative stay was 4 (2-24) days. The median follow-up period was 43.0 (30.1-167.9) months. Five-year overall survival rate was 99.5% [95%CI (98.8%, 100.0%)], 5-year recurrence-free survival rate was 98.8% [95%CI (97.5%, 100.0%)], and 5-year lung cancer-specific survival rate was 100.0%. Conclusion    Anatomic segmentectomy has favorable perioperative outcomes and excellent prognosis in GGO dominant early stage lung cancer patients.

ABSTRACT

@#Objective     To identify the risk factors for postoperative recurrence of peripheral solid small-nodule lung cancer (PSSNLC) (T≤2 cm), and to explore the effects of surgery types on prognosis. Methods     We extracted data from Western China Lung Cancer Database (WCLCD), a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University, and Surveillance, Epidemiology, and End Results (SEER)  database for peripheral solid small-nodule lung cancer patients (T≤2 cm N0M0, stageⅠ) who underwent surgery between 2005 and 2016. We used univariable and multivariable logistic regression to analyze risk factors for recurrence of PSSNLC. We applied propensity-score matching to compare the long-term results of segmentectomy and lobectomy, as well as the survival of patients from WCLCD and SEER. We finally included 4 800 patients with PSSNLC (T≤2 cm N0M0)(WCLCD: SEER=354∶4 446). We matched 103 segmentectomies and 350 lobectomies in T≤1 cm, and 280 segmentectomies and 1 067 lobectomies in 1 cm<T≤2 cm at a ratio of 1∶4 according to the propensity scores. Results     The results of multivariable logistic regression showed that older age (HR=1.04, 95%CI 1.03-1.05, P<0.001), male (HR=1.60, 95%CI 1.37-1.88, P<0.001), squamous carcinoma (HR=1.65, 95%CI 1.40-1.95, P<0.001), lymph node removed (HR=0.97, 95%CI 0.96-0.99, P<0.001) were risk factors for recurrence after surgery. We found that segmentectomy and lobectomy could reach similar survival in PSSNLC patient with either T≤1 cm or 1 cm<T≤2 cm. Analyses of 1 441 patients with PSSNLC after matching (WCLCD∶SEER=325∶1 116) indicated that the 5-year overall survival rate of the patients in WCLCD was better than that in SEER database ( 89.8% vs. 77.1%, P<0.001). Conclusion     Older age, male, squamous carcinoma, and lymph node removed are the risk factors for recurrence of PSSNLC. Segmentectomy shows similar survival in PSSNLC patient with either T≤1 cm or 1 cm<T≤2 cm N0M0. The patients in the WCLCD shows better survival compared with of the patients in the SEER database.
