Objective To compare the clinical effects between uniportal video-assisted thoracic surgery (VATS) and 3-portal VATS lobectomy for patients with lung cancer. Methods Patients were divided into uniportal VATS lobectomy group (n=45) and 3-portal VATS lobectomy group (n=53). The clinical data were compared between two groups, including the oper-ation time, intraoperative blood loss, number of lymph node dissection, length of incision, postoperative extubation time, post-operative pain score and postoperative hospitalization. Results There were no significant differences in intraoperative blood lose (128.75±18.32) mL vs (129.15±17.69) mL, lymph node dissection number (13.33±1.05) vs (13.12±1.38), duration of chest drainage (4.90±0.75)d vs (4.75±0.70)d, duration of hospital stay (7.52±1.16)d vs (7.55±1.10)d and incidence of seri-ous postoperative complications between two groups (P>0.05). The incision length (5.36±0.22)cm vs (7.44±0.35)cm, numeric pain intensity scale including first day(6.47±0.54) vs (6.86±0.52),third day(3.59±0.29) vs (4.05±0.25), and patient satisfac-tion scores (91.03 ± 2.62) vs (88.35 ± 2.97) were significantly better in uniportal VATS group than those of 3-portal VATS group (P<0.05). The operation time (143.81±17.97) min vs(130.11±15.03)min was longer in uniportal VATS group than that of 3-portal VATS group (P < 0.05). Conclusion Uniportal VATS lobectomy is safe and reliable for patients with early-stage lung cancer, which has less surgical injury, slighter pain, and higher satisfaction than 3-portal VATS lobectomy.

Objective To investigate the association between the genetic polymorphisms in GSTA1 and the clinical outcome of breast cancer patients treated with cyclophosphamide-based adjuvant chemotherapy. Methods A total of 137 breast cancer patients receiving cyclophosphamide-based adjuvant chemotherapy were recruited ( 124 cases with infiltrative ductal carcinoma, 5 cases with infiltrative lobular carcinoma and 8 cases with other histological types). PCR-LDR method was used to detect the genotypes of GSTA1. Survival curves were generated by the Kaplan-Meier method, and verified by the log-rank test. Cox proportional hazards regression analysis was used to estimate the prognostic factors in multivariate analysis. Results Of the 137 breast cancer patients, the genotypic frequencies of the GSTA1 * A/* A,* A/* B and * B/* B were 67.2% ( 92/137 ), 31.4% ( 43/137 ) and 1.5% ( 2/137 ), respectively. No significant differences were found between the genotypic frequencies and groups categorization according to age, stage, lymph node metastasis, ER or PR status (x2 = 0. 722,1. 967, 3. 303, 0. 226 and 0. 709, all P ＞0. 05 ) ;through Fisher exact test, also no significant differences were found between the genotypic frequencies and group categorization according to tumor size, histological types and grading ( all P ＞ 0. 05 ) . The recurrence rates in patients with GSTA1 * A/* A and * A/* B or * B/* B genotypes were 47. 8% (44/92) and 31.1% ( 14/45 ), respectively, and the mortality rates were 22. 8% ( 21/92 ) and 17. 8% ( 8/45 ),respectively. Patients with GSTA1 * A/* B and * B/* B genotypes were significantly associated with reduced hazard of relapse (x2 =18.723, P＜0. 01)and mortality (x2 =7.352, P＜0.01), compared to cases with the common * A/* A genotypes, according to Kaplan-Meier survival analysis and log-rank test. Moreover,Cox multivariate analysis showed that GSTA1 polymorphisms appeared to be an independent risk factor for recurrence-free survival ( OR =0. 222, 95% CI:0. 108-0. 458, P ＜0. 01 ) and overall survival ( OR =0. 362,95% CI:0. 145-0. 902, P ＜ 0. 05 ). Conclusion These data indicate that GSTA1 polymorphism may be a potential prognostic factor for recurrence-free survival and overall survival in breast cancer patients treated with cyclophosphamide-based adjuvant chemotherapy.

In recent years, the management of respiratory diseases related to preterm birth has received extensive attention.In 2021, the American Thoracic Society brought together multidisciplinary experts in respiratory, neonato-logy, otolaryngology, sleep medicine, radiology and nursing specialties to develop Guidelines for outpatient respiratory management in infants, children, and adolescents with post-preterm respiratory disease (hereinafter referred to as the " Guideline" ), aiming to provide evidence-based medical evidence for standardized outpatient management of respiratory diseases associated with preterm birth at different ages.The Guideline was interpreted and summarized so that pediatric clinicians could correctly diagnose and treat these diseases, and understand and implement standardized outpatient management on the basis of evidence.

Objective To study l-arginine aerosolized inhalation's protective effect on pulmonary ventilation of the pulmonary-arterial-hypertension patients during the early stage after pulmonary lobectomy,and its preventive effect on reducing postoperative complications.Methods 54 cases of pulmonary lobectomy patients with preoperative plumonary arterial hypertension were divided into two groups randomly-Group A was given L-arginine aerosolized inhalation within 4 h after the operation;Group B was given the same dose of aerosolized inhalation of physiological saline as contrast(other postoperative medication being the same with Group A).Compare the two groups of patients in terms of oxygenation index(PaO2/FiO2),alveolararterial oxygen difference(PA-aO2),nitric oxide(NO) concentration,ultrasonic cardiogram,mechanical ventilation duration,ICU duration,occurances of hemodvnamic disturbance and arrhythmia,and differences in postoperative hospital stay.Results The oxgenation index and the content of NO in plasma of Group A were higher than that of Group B(P ＜0.001);the alveolar-arterial oxygen difference and the postoperative pulmonary arterial pressure detected by UCG of Group A were lower than that of Group B(P ＜ 0.001);the postoperative mechanical ventilation duration,ICU duration,occurances of hemodynamic disturbance and arrhythmia of Group A were all lower than that of Croup B(P ＜ 0.05).Conclusion The postoperative l-arginine aerosolized inhalation during the early stage after pulmonary lobectomy has positive effect on the lung protection of the pulmonary-arterial-hypertension patients and it can reduce the perioperative complications and postoperative hospital stay of such patients.

Objective To investigate the clinical features and gene mutations of 3M syndrome. Method The clinical data of a child with 3M syndrome was retrospectively analyzed. The DNA was extracted from the peripheral blood of the child and parents, and the sequence analyses were performed by Agilent SureSelect exon capture and Illumina HiSeq sequencing platform. And the mutant gene was validated by Sanger sequencing. Results The six-month-old girl presented special face and growth retardation.The girl had a missense mutation c.4898C>T,p.T1633M in the CUL7 gene(NM_014780.4),and both her parents had heterozygous mutations.The girl was diagnosed with 3M syndrome.Conclusions The CUL7 mutation is the major causative gene of 3M syndrome in this girl. Early gene testing should be performed to confirm the diagnosis in suspected clinical phenotype.

The lung is the second most common site of neuroendocrine tumors (NETs). Typical and atypical carcinoids are low-grade NETs of the lung. These rare tumors have received little attention and education is needed for treating physicians. The article describes the classifcation of lung NETs, the epidemiology and pathological characteristics. When lung NETs are diagnosed at an early stage, surgical intervention is often curative. For advanced lung NETs patients, different treatment methods including chemotherapy, somatostatin analogs, m-TOR inhibition, peptide receptor radioligand therapy, and biologic systemic therapy are discussed. The conclusions are generally extrapolated from the outcome of extra-pulmonary carcinoids. Prospective randomized well-designed trials are urgently needed to inform current recommendations on systemic treatment.
