Objective:To evaluate the safety and efficacy of ultrasound-guided percutaneous negative pressure suction and minimally invasive rotatory excision technique for the treatment of complex encapsulated lesions.Methods:A total of 48 patients(48 lesions) with complex encapsulated lesions who underwent ultrasound-guided percutaneous negative pressure suction and minimally invasive rotatory excision technique at Xi′an Chest Hospital from January to October 2023 were retrospectively enrolled, including 39 cases of encapsulated abscess, 7 cases of encapsulated effusion, and 2 cases of encapsulated haematoma; the distribution of the bacterial flora of the abscesses were as follows: 24 cases of tuberculous abscess, 14 cases of bacterial abscess, 1 case of bacterial combined bacterial-fungal abscess, and 7 cases of encapsulated effusion were tuberculous pleurisy, and the clinical data were analysed retrospectively. The maximum upper and lower diameters, right and left diameters, and anterior and posterior diameters of the lesions were measured by ultrasound before and after the operation. The patients′ various biochemical indicators (C-reactive protein, white blood cell count, neutrophil count, erythrocyte sedimentation rate) were detected. The intraoperative and postoperative complications, postoperative outcomes, and postoperative clinical symptoms were recorded.Results:Of the 48 patients, 39 were cured and discharged after negative pressure suction and rotatory excision technique, and 9 patients were cured and discharged after surgical incision and drainage of the lesions. The overall effective rate of negative pressure suction and rotatory excision treatment reached 81.25%, and the average number of days of tube placement was (11.81±7.22) days, and the average number of days of follow-up was (35.77±19.39) days. Compared with preoperative values, the upper and lower diameters, the left and right diameters, and the anterior and posterior diameters of the lesions were all reduced after operation [5.80 (4.95, 7.95)cm vs 8.00 (6.00, 11.82)cm, 4.00 (3.25, 5.00)cm vs 5.85 (4.52, 7.65)cm, 1.80 (1.00, 2.90)cm vs 3.40 (2.50, 6.15)cm, all P<0.01]; and postoperative C-reactive protein, white blood cell count and neutrophil count all decreased (all P<0.05). Before operation there were 31 cases of local swelling, 16 cases of pain, 12 cases of activity limitation, 12 cases of fever, 7 cases of chest tightness, and 6 cases of shortness of breath, and during postoperative follow-up, there were 4 cases of local swelling, 5 cases of pain, and 4 cases of activity limitation. The symptoms of fever, chest tightness, and shortness of breath all disappeared, and there was a statistically significant difference between preoperation and postoperation (all P<0.05). There were no adverse events or complications associated with the intraoperative and postoperative follow-up of negative pressure suction and rotatory excision treatment. Conclusions:Ultrasound-guided percutaneous negative pressure suction and invasive rotatory excision technique for the treatment of complex encapsulated lesions can significantly reduce lesion size, reduce inflammatory response and improve patient symptoms, which is a safe, effective and minimally invasive technique.

Nutritional therapy is a core component of critically ill patient management,and the enteral route has become the preferred method due to its dual roles of nutrition and non-nutrition. The use of vasoactive medications makes enteral nutrition decisions more challenging for these patients. This review systematically examines the pathophysiological effects of vasoactive medications on gastrointestinal tract of critically ill patients,the current value and safety of enteral nutrition in this patient's population,summarizes the optimal strategies for implementing enteral nutrition in these patients for clinical reference.

With the aging process of population in the society, the prevalence of cardiovascular diseases (CVD) in China is increasing continuously and the number of dental patients with CVD is increasing gradually too. Due to the lack of guidelines for dental patients with CVD in our country, how to implement standardized preoperative evaluation and perioperative risk prevention remains a problem to be solved for dentists at present. The present expert consensus was reached by combining the clinical experiences of the expert group of the Fifth General Dentistry Special Committee, Chinese Stomatological Association and respiratory and cardiology experts in diagnosis and treatment for CVD patients, and by systematically summarizing the relevant international guidelines and literature regarding the relationship between CVD and oral diseases and the diagnosis and treatment of dental patients with heart failure, hypertension and antithrombotic therapy. The consensus aims to provide, for the dental clinicians, the criteria on diagnosis and treatment of CVD in dental patients in China so as to reduce the risk and complications, and finally to improve the treatment levels of dental patients with CVD in China.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.

OBJECTIVE: To investigate the incidence of neonatal asphyxia and possible contributing factors for the development of severe asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture, China. METHODS: A total of 16 hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture were selected as research centers. A retrospective analysis was performed for the clinical data of 22 294 live births in these 16 hospitals from January to December, 2016 to investigate the incidence rate of neonatal asphyxia and possible contributing factors for the development of severe asphyxia. RESULTS: Of the 22 294 neonates born alive, 733 (3.29%) were diagnosed with neonatal asphyxia, among whom 627 had mild asphyxia and 106 had severe asphyxia. The neonates with low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight had a higher incidence of severe asphyxia (P<0.05). CONCLUSIONS The incidence rate of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture is higher. Low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight may be related to the development of severe neonatal asphyxia.

Background: Prospective real-life data on the safety and effectiveness of rituximab in Chinese patients with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) are limited. This real-world study aimed to evaluate long-term safety and effectiveness outcomes of rituximab plus chemotherapy (R-chemo) as first-line treatment in Chinese patients with DLBCL or FL. Hepatitis B virus (HBV) reactivation management was also investigated. Methods: A prospective, multicenter, single-arm, noninterventional study of previously untreated CD20-positive DLBCL or FL patients receiving first-line R-chemo treatment at 24 centers in China was conducted between January 17, 2011 and October 31, 2016. Enrolled patients underwent safety and effectiveness assessments after the last rituximab dose and were followed up for 3 years. Effectiveness endpoints included progression-free survival (PFS) and overall survival (OS). Safety endpoints were adverse events (AEs), serious AEs, drug-related AEs, and AEs of special interest. We also reported data on the incidence of HBV reactivation. Results: In total, 283 previously untreated CD20-positive DLBCL and 31 FL patients from 24 centers were enrolled. Three-year PFS was 59% (95% confidence interval [CI]: 50-67%) for DLBCL patients and 46% (95% CI: 20-69%) for FL patients. For DLBCL patients, multivariate analyses showed that PFS was not associated with international prognostic index, tumor maximum diameter, HBV infection status, or number of rituximab treatment cycles, and OS was only associated with age >60 years (P < 0.05). R-chemo was well tolerated. The incidence of HBV reactivation in hepatitis B surface antigen (HBsAg)-positive and HBsAg-negative/hepatitis B core antibody-positive patients was 13% (3/24) and 4% (3/69), respectively. Conclusions: R-chemo is effective and safe in real-world clinical practice as first-line treatment for DLBCL and FL in China, and that HBV reactivation during R-chemo is manageable with preventive measures and treatment.

Objective To evaluate the feasibility and safety of cap-assisted endoscopic nylon loop ligation (C-ENLL) as a new and simple method on gastric fundus submucosal tumors. Methods 74 cases with small gastric fundus submucosal tumors ≤2.00 cm in diameter were reviewed between January 2015 and June 2016. All cases were treated by C-ENLL. The clinical efficacy was analyzed. Results All the 74 patients underwent endoscopic ultrasonography before operation, 70 cases originated from the muscularis propria, 3 cases originated from the muscularis mucosae, 1 case originated from the submucosa. The average diameter of the lesions ranged 0.50 ～ 1.80 cm. C-ENLL achieved an en bloc resection rate of 100.0％, with a mean total procedure time of 26 min. Two patients developed delayed perforation, were treated with nylon rope and metal clip purse suture wound. All of whom were managed successfully. There was no delayed bleeding after operation. Pathological examination showed that 66.2％ (49/74) of the tumors were gastrointestinal stromal tumors. No tumor recurrence was observed during the follow-up. Conclusion The C-ENLL may be a feasible and safe method for the treatment of small gastric fundus submucosal tumors.

OBJECTIVETo analyze the therapeutic effect of human neural precursor cells transplantation in treatment of neonates with severe brain injury.

METHODThe transplantation was performed on 6 newborns, one of them was diagnosed as extremely severe carbon monoxide poisoning at 5(th) day after birth; one of them was diagnosed as severe hypoglycemia; the others had asphyxia at birth with Apgar scores from 1 to 3 and were diagnosed as severe neonatal asphyxia, severe hypoxic ischemic encephalopathy according to images, electroencephalogram, biochemical examination and clinical manifestation. With the approval of hospital ethics committee and informed consent of the family members, the newborns received human neural precursor cells transplantation at the 4(th) to 20(th) day after birth. With the agreement of a pregnant woman, forebrain cells were obtained from the forebrain of her 12-week old fetus after spontaneous abortion. The cells from the fetal brain were amplified into human neural precursor cells in vitro and were injected into the cerebral ventricle of the patients.

RESULTOn the 2(nd) day after transplantation, sucking and swallowing reflexes gradually appeared in all the patients, muscular tension was also improved, and convulsion stopped. NBNA scoring in 3 of the patients reached normal level on the 28(th) day after birth. The 6 patients were followed up for 12 months. Four patients were normal in psychomotor development and scores of each scale reached normal level. Two patients have cerebral palsy.

CONCLUSIONhNPCs transplantation is safe and effective in treatment of severe neonatal brain injury. More clinical trials and further observation are needed.

OBJECTIVETo investigate the role of dynactin 1 (Dctn1) in the process of mouse spermiogenesis.

METHODSWestern blot and indirect immunofluorescence were used to analyze the expression and location of Dctn1 in the mouse testis and spermatozoa. The highest efficiency of small interference RNA (siRNA) was verified by GC2-spd cell line in vitro and in vivo studies, respectively. Dctn1 siRNA mixed with the indicator (0.4% trypan blue) was injected into the seminiferous tubules of 3-week-old ICR mice through rete testis microinjection, and negative control siRNA injected into the control testes. The normal group included 3-week-old ICR mice that did not receive any treatment. Spermatozoa were collected from the cauda epididymis 3 weeks after siRNA injection for morphological analysis.

RESULTSDctn1 was mainly localized in the tail of spermatozoa. After interference, the sperm tail abnormality in the Dctn1 siRNA group was (23.57 +/- 0.55)%, significantly higher than (12.35 +/- 2.29)% in the control (P < 0.01, n = 3), and it was (3.37 +/- 0.69)% in the normal group.

CONCLUSIONDctn1 plays an important role in mouse spermiogenesis, and mainly affects the formation of the tail of spermatozoa.
