Objective:This meta-analysis aims to explore the most consistent changes in cortical thickness in drug-naive first-episode patients with major depressive disorder (DF-MDD).Methods:Systematic and comprehensive searches were conducted to acquire relevant literature from the PubMed and Web of Science databases for the studies published from inception to July 23, 2023, by using the keywords ("depression" OR "depressive disorder" OR "unipolar depression") AND ("cortical thickness"OR"thickness"). The SDM (signed differential mapping) software was used to perform whole-brain voxel-wise meta-analysis, heterogeneity test, and assess publication bias. Meta-regression analysis was employed to examine the impact of disease severity on cortical thickness in depression, and heterogeneity was tested, along with an assessment of publication bias.Results:Eight studies were ultimately included, encompassing 417 DF-MDD patients and 409 healthy controls. Compared to the healthy control group, DF-MDD patients exhibited significantly decreased cortical thickness in multiple brain regions, including the supplementary motor area ( Z=-2.471, P<0.000 5) and the rolandic operculum ( Z=-2.190, P<0.000 5). Further regression analysis found that the disease severity was positively correlated with the cortical thickness in the supplementary motor area ( Z=2.265, P<0.000 5) and the rolandic operculum ( Z=1.56, P<0.000 5). Additionally, the average depressive duration was positively correlated with cortical thickness in the right opercular part of the inferior frontal gyrus ( Z=1.922, P<0.000 5), and negatively correlated with changes in the right midcingulate cortex ( Z=-3.035, P<0.000 5) in DF-MDD. Conclusion:DF-MDD patients exhibit reduced cortical thickness in the supplementary motor area and the operculum area during the early stages of the disease. And the observed pattern of cortical alterations is associated with both the severity and duration of the disease.

Objective To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. Methods We retrospectively enrolled 100 patients who underwent VATS segmentectomy for bilateral lung cancer at the Department of Thoracic Surgery of Peking Union Medical College Hospital from December 2013 to May 2022. We divided the patients into two groups: a one-stage group (52 patients), including 17 males and 35 females with a mean age of 55.17±11.09 years, and a two-stage group (48 patients), including 16 males and 32 females with a mean age of 59.88±11.48 years. We analyzed multiple intraoperative variables and postoperative outcomes. Results All 100 patients successfully completed bilateral VATS, and at least unilateral lung received anatomical segmentectomy. Patients in the one-stage group were younger (P=0.040), had lower rate of comorbidities (P=0.030), were less likely to have a family history of lung cancer (P=0.018), and had a shorter interval between diagnosis and surgery (P=0.000) compared with patients in the two-stage group. Wedge resection on the opposite side was more common in the one-stage group (P=0.000), while lobectomy was more common in the two-stage group. The time to emerge from anesthesia in the one-stage group was longer than that in the first and second operations of the two-stage group (P=0.000, P=0.002). Duration of surgery and anesthesia were similar between two groups (P>0.05). Total number of lymph node stations for sampling and dissection (P=0.041) and lymph nodes involved (P=0.026) were less in the one-stage group. Intraoperative airway management was similar between two groups (P>0.05). The one-stage group was associated with lower activities of daily living (ADL) scores. Conclusion Segmentectomy is safe in one- or two-staged VATS for bilateral lung cancer, including contralateral sublobectomy and lobectomy. Duration of surgery and perioperative complications are similar between two groups, but the one-stage group is associated with lower ADL scores. On the basis of comprehensive consideration in psychological factors, physical conditions and personal wishes of patients, one-staged sequential bilateral VATS can be the first choice.

Objective:To study the clinicopathological features, immunophenotype, molecular genetic characteristics and prognosis of renal cell carcinoma associated with TFEB gene rearrangement (TFEBr-RCC).Methods:Eight cases of TFEBr-RCC diagnosed at the West China Hospital of Sichuan University from 2014 to 2022 were collected for clinicopathological, immunohistochemical, fluorescence in situ hybridization and RNA sequencing analyses, with review of literature.Results:Six patients were male and two were female. The patient ages ranged from 25 to 50 years (mean: 34 years, median: 32 years). The tumors were present in the right kidney (3 cases) or the left kidney (5 cases). The maximum diameters of the tumors ranged from 4.0 cm to 18.5 cm, with an average of 8.5 cm. Histologically, majority of the cases (5/8) showed typical biphasic "pseudorosette" structure, while the remaining three cases demonstrated atypical morphology that was similar to epithelioid angiomyolipoma or clear cell renal cell carcinoma. Immunohistochemical study showed positivity of TFEB (8/8), PAX8 (8/8), MART-1 (7/7), and HMB45 (5/6). Interestingly, PD-L1 was variably expressed in all five tested cases. Staining for TFE3 in all cases was negative. TFEB translocation was verified in all 8 cases using TFEB fluorescence in situ hybridization. RNA sequencing showed MALAT1-TFEB gene fusion in 4 of the 5 tested cases (two of which showing novel MALAT1-TFEB fusion sites), and one case with a novel ACTB-TFEB gene fusion. Patient follow-ups ranged from 5 to 96 months (average 47 months). All patients were alive without recurrence or metastasis.Conclusions:TFEBr-RCC tends to occur in young adults and has a good prognosis. Histologically, most of the cases show characteristic biphasic structure, and some cases show epithelioid angiomyolipoma-like or clear cell RCC-like morphology. Immunohistochemical reactivity to TFEB, melanocytic markers and PD-L1 is characteristic. MALAT1-TFEB gene fusion is the most common molecular change, with variable fusion sites.

Thymic neuroendocrine tumors (TNETs) are a series of rare diseases with aggressive biology and poor prognosis. Clinical manifestations of TNETs are atypical, and ectopic secretion of adrenocorticotropic hormone can be found in some cases, resulting in associated endocrine symptoms. Due to the low morbidity and strong heterogeneity, it’s difficult to diagnose, treat and obtain new treatment regimen. Early complete surgical resection is an effective treatment. For advanced cancer, clinical trials of new drugs are expected to improve the survival of patients.

ObjectiveTo explore the underlying mechanism of Bushen Huatan prescription in alleviating postmenopausal osteoporosis (PMOP) by maintaining the balance of osteogenesis and adipogenic differentiation in ovariectomized rats with osteoporosis. MethodSeventy-five 6-month-old non-pregnant female SD rats were randomly divided into sham-operation group, model group, atorvastatin group, liviol group, and Bushen Huatan prescription group. Bilateral ovaries were removed in the four groups except the sham-operation group, while only the same mass of adipose tissue around the ovaries was removed in the sham-operation group. On the 5th week after surgery, drugs were consecutively administrated for 8 weeks. Rats in the Bushen Huatan prescription group received 9.4 mg·kg-1 of the prescription, rats in the atorvastatin group received 0.92 mg·kg-1 of atorvastatin, rats in the Liviol group received 0.23 mg·kg-1 of liviol, and rats in the model group and the sham-operation group received saline once a day. Micro-computed tomography (Micro CT) was used to detect bone mineral density (BMD) of rat tibia in each group. Hematoxylin-eosin (HE) staining was used to detect the relative area of rat bone marrow adipose tissue (BMAT) in each group. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were used to detect the relative expression levels of Runt-related transcription factor 2 (Runx2), peroxisome proliferator-activated receptor (PPARγ), leptin (LPN), and leptin receptor (OBR) in bone tissues. ResultAs compared with the sham operation group, the BMD of rats in the model group decreased (P<0.05), while the relative area of BMAT increased (P<0.05). In addition, the expression levels of LPN, OBR, and Runx2 decreased in the model group (P<0.05), while the level of PPARγ increased (P<0.05). As compared with the model group, the BMD of rats in the atorvastatin group, the Livial group, and the Bushen Huatan prescription group increased (P<0.05), and the relative area of BMAT decreased (P<0.05). The expression levels of LPN, OBR, and Runx2 in these groups increased (P<0.05), while the expression level of PPARγ decreased (P<0.05). ConclusionBushen Huatan prescription plays the anti-osteoporosis role in the rat model of PMOP through up-regulating LPN and OBR in bone tissues and maintaining the balance of osteogenesis and adipogenic differentiation, thereby reducing postmenopausal bone loss and playing a role in the prevention and treatment of PMOP.

Pulmonary inflammatory myofibroblastic tumor (PIMT) is a rare lung tumor that is poorly understood by clinicians. Based on the data of patients with PIMT in our center, a comprehensive search and a brief summary analysis of previous reports of the disease were carried out in this article. PIMTs were more likely to be present in male patients and in the right lung, and their clinical and radiographic findings were heterogeneous. Surgery is the most important treatment method, and complete resection is of great significance to the prognosis of patients. Targeted therapy represented by crizotinib may be helpful for patients with positive ALK mutations.

In order to improve the salt tolerance of banana NHX genes, we cloned a MaNHX5 gene from Musa acuminata L. AAA group and predicted the key salt-tolerant amino acid sites and mutant protein structure changes of MaNHX5 by using bioinformatics tools. The 276-position serine (S) of MaNHX5 protein was successfully mutated to aspartic acid (D) by site-directed mutagenesis, and the AXT3 salt-sensitive mutant yeast was used for a functional complementation test. The results showed that after the mutated MaNHX5 gene was transferred to AXT3 salt-sensitive mutant yeast, the salt tolerance of the mutant yeast was significantly improved under 200 mmol/L NaCl treatment. It is hypothesized that Ser276 of MaNHX5 protein plays an important role in the transport of Na+ across the tonoplast.
