ABSTRACT

Objective To study and analyze the trend of diabetes death and the impact of life expectancy in Qidong City, Jiangsu Province from 1990 to 2019, and to provide a basis for formulating health policies. Methods Based on the surveillance data of deaths from all causes in Qidong City and the population data over the years from 1990 to 2019, the residents' diabetes mortality and temporal trends were analyzed. Joinpoint4.7.0.0 software was used to calculate relevant indicators including crude mortality (CR), age-standardized rates by China population (CASR), annual percentage change (APC), potential years of life lost (PYLL), and potential years of life lost rate (PYLLR). Results The CR of diabetes in Qidong City from 1990 to 2019 was 15.12/100 000, with a rate of 12.72/100 000 in males and a rate of 17.45/100 000 in females. The total CASR was 7.58/100 000, including 6.47/100 000 for males and 8.59/100 000 for females. Trend analysis showed that the APC of CR and CASR was 9.31% and 5.26% in males, and 8.12% and 4.40% in females, respectively. The APC of CR and CASR in the 45-64 years old group was 2.59% and 4.85%, respectively. The APC of CR and CASR in the 65 years old and above group was 7.20% and 9.79%, respectively. There were statistically significant differences except for the 15-44 years old group. The life expectancy of residents in Qidong City rose from 73.95 years in 1990 to 82.91 years in 2019 (APC=0.38, P<0.001), and life expectancy without diabetes rose from 74.01 years in 1990 to 83.39 years in 2019 (APC=0.39, P<0.001). Conclusion In the past 30 years, the diabetes mortality and life loss of residents in Qidong City have been increasing year by year and the trend is obvious. Women's diabetes mortality and life loss are higher than those in men. The level and increase rate of diabetes mortality in the high age group are higher than those in the low age group. It is necessary to carry out key intervention for the corresponding population.

ABSTRACT

OBJECTIVE@#To explore the clinical value of three-dimensional (3D) visualization technique in laparoscopic D3 radical resection of right colon cancer.@*METHODS@#We retrospectively analyzed the clinical data of 73 patients with right colon cancer undergoing laparoscopic D3 radical operation in our hospital between May, 2019 and March, 2021. Among these patients, 41 underwent enhanced CT examination with 3D visualization reconstruction to guide the actual operation, and 32 underwent enhanced CT examination only before the operation (control group). In 3D visualization group, we examined the coincidence rate between the 3D visualization model and the findings in surgical exploration of the anatomy and variations of the main blood vessels, supplying vessels of the tumor, and the tumor location, and the coincidence rate between the actual surgical plan for D3 radical resection of right colon cancer and the plan formulated based on the 3D model. The operative time, estimated blood loss, unexpected injury of blood vessels, number of harvested lymph nodes, mean time of the first flatus, complications, postoperative hospital stay and postoperative drainage volume were compared between the two groups.@*RESULTS@#The operative time was significantly shorter in 3D visualization group than in the control group (P < 0.05). The volume of blood loss, proportion of unexpected injury of blood vessel, the number of harvested lymph nodes, time of the first flatus, proportion of complications, postoperative hospital stay and postoperative drainage volume did not differ significantly between the two groups (P > 0.05). In the 3D visualization group, the 3D visualization model clearly displayed the shape and direction of the colon, the location of the tumor, the anatomy and variation of the main blood vessels and the blood vessels supplying the cancer, and showed a coincidence rate of 100% with the findings by surgical exploration. The surgical plan for D3 radical resection of right colon cancer was formulated based on the 3D model also showed a coincidence rate of 100% with the actual surgical plan.@*CONCLUSION@#The 3D visualization reconstruction technique allows clear visualization the supplying arteries of the tumor and their variations to improve the efficiency, safety and accuracy of laparoscopic D3 radical resection of right colon cancer.

ABSTRACT

Objective: To explore the dynamic changes of vestibular autorotation test (VAT) before and after vestibular rehabilitation treatment in patients with unilateral vestibular hypofunction (UVH). Methods: A retrospective study was carried out,48 patients who were diagnosed with UVH and under vestibular rehabilitation in department of otorhinolaryngology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2019 to January 2021 were enrolled. Among them, there were 21 males and 27 females, with an average age of 46.9 years old, including 25 cases of Meniere's disease, 13 cases of sudden deafness with vertigo and 10 cases of vestibular neuritis. The course of disease ranged from 5 days to 10 years. Demographic characteristics, detailed case data and routine examination were collected for the patients. The horizontal gain/phase, vertical gain/phase, and asymmetry of VAT at different frequencies before and after vestibular rehabilitation were collected. The absolute value of the difference between the measured value of 2.0-5.9 Hz before and after rehabilitation and the standard value were statistically analyzed. Results: Before vestibular rehabilitation, the incidence of abnormal gain was 62.5% (30/48), the incidence of abnormal phase was 56.3% (27/48), and the incidence of asymmetry was 16.7% (8/48). After 4-6 weeks of vestibular rehabilitation, the incidence of gain abnormality was 22.9% (11/48), the incidence of phase abnormality was 31.3% (15/48), and the incidence of asymmetry was 12.5% (6/48).The horizontal gain at frequency of 2.0-3.9 Hz showed statistically significant difference compared with before vestibular rehabilitation (P<0.05), and the horizontal gain at frequency of 4.3-5.9 Hz showed that there was no significant difference (P>0.05); the horizontal phase at 5.9 Hz showed that the difference was statistically significant (P=0.043), and there was no significant difference before and after rehabilitation treatment at 2.0-5.5 Hz (P>0.05); the vertical gain at 4.3 Hz showed the difference was statistically significant (P=0.020), and the remaining frequency showed no significant difference (P>0.05); No frequency of asymmetry and vertical phase showed the difference before and after rehabilitation was statistically significant (P>0.05). Conclusion: VAT can be used to monitor the change trend of multiple frequency bands before and after vestibular rehabilitation in UVH, in order to provide reference for the formulation of personalized rehabilitation strategies.

ABSTRACT

OBJECTIVE@#To analyze the effects of ozone (O3) concentrations measured with different approaches across different seasons on the total number of childhood asthma-related clinical visits, as well as the differentiation of such effects across different groups of patients.@*METHODS@#The outpatient data of three grade A tertiary hospitals in Lanzhou City spanning from 1 January 2014 to 31 December 2017, as well as air pollution and meteorological data during the same period were collected. Considering the nonlinear relationship between O3 concentrations and the total number of childhood asthma-related clinical visits and meteorological factors, a generalized additive temporal sequence model was employed to analyze the short-term association between changes in O3 concentrations and the total number of childhood asthma-related clinical visits. Taking into account of the variations in O3 concentrations within 1 day, this study adopted different measurement approaches to address the three types of O3 exposures, namely, the maximum 1 h daily concentration (O3max1h), the maximum 8 h daily concentration (O38h) and the mean 24 h daily concentration (O324h) as the short term exposure indicators to O3, followed by a model-based analysis.@*RESULTS@#The increase in short-term exposure levels to O3 in summer had a significant effect on the increase in the total number of childhood asthma-related clinical visits. With lag0 for the current day, every 10 μg/m3 increase in atmospheric concentration of O3max1h was associated with an increase in the total number of childhood asthma-related clinical visits by 3.351% (95%CI: 1.231%-5.516%); for every 10 μg/m3 increase in O38h concentration, the total number of childhood asthma-related clinical visits increased by 3.320% (95%CI: 0.197%-3.829%); for every 10 μg/m3increase in O324h concentration, the total number of childhood asthma-related clinical visits in summer increased by 6.600% (95%CI: 0.914%-12.607%); moreover, an increase in exposure to O3max1h also led to a significant rise in the total number of childhood asthma-related clinical visits among the males.@*CONCLUSION@#The increase in short-term exposure levels to O3 in summer in Lanzhou City has a significant effect on the increase in the total number of childhood asthma-related clinical visits; O3max1h is more closely correlated with the increase in the total number of childhood asthma-related clinical visits.

ABSTRACT

Laparoscopic techniques are more and more poplular in proximal gastrectomy. The traditional esophagogastric anastomosis may lead to severe reflux esophagitis after surgery, affecting patient's quality of life. In recent years, multiple methods of digestive tract reconstruction after laparoscopic proximal gastrectomy capable of resisting reflux have been applied to the clinic. Combining the results of the latest clinical studies and our clinical experience, we elaborate the views on digestive tract reconstruction after laparoscopic proximal gastrectomy. Esophagogastric anastomosis (posterior esophagogastric anastomosis, anterior esophagogastric anastomosis, gastric tube reconstruction, lateral esophagogastric anastomosis, Kamikawa anastomosis and modified Kamikawa anastomosis, etc.) and esophagojejunal anastomosis (interposition jejunum, interposition jejunum with pouch, and double-channel anastomosis, etc.) are mainly discussed. Of course, the anti-reflux mechanisms of different surgical procedures are not the same, the anti-reflux effects are variable, and the surgical difficulties under laparoscopy are also different. Therefore, how to choose a rational reconstruction method after proximal gastrectomy needs to be comprehensively considered based on patient's own situation and technical level of the surgeons.

ABSTRACT

OBJECTIVES@#There is less clinical data on multiple myeloma (MM) in China, and the aim of this study was to collect and analyze the clinical data of newly diagnosed multiple myeloma (NDMM) patients in Hunan Province during 1 year, to understand the real clinical features and treatment outcome for Hunan Province patients with MM, and to strengthen the understanding of the standardized diagnosis process and treatment plan of MM.@*METHODS@#The clinical data of 529 patients with NDMM in 12 large-scale general hospitals in Hunan Province from January 1 to December 31, 2019 were collected and analyzed, including baseline data, treatment regimens, duration of treatment, and adverse reactions. The clinical characteristics, treatment, and safety of patients were analyzed by SPSS 21.0.@*RESULTS@#Among the 529 NDMM patients, the age was 33-90 (median 64) years and the male-female ratio was 1.38꞉1. The clinical features ranged from high to low were as follows: Bone pain (77.7%), anemia (66.8%), renal insufficiency (40.6%), hypercalcemia (15.1%). Typing: IgG 46.5%, IgA 24.6%, IgD 2.6%, IgM 0.8%, light chain 15.7%, double clone 3.0%, no secretion 0.6%, absence 6.2%. Staging: Durie-Salmon stage I, II, and III were 4.5%, 10.6%, 77.3%, respectively, and 40 cases (7.6%) missed this data. International Staging System (ISS) stage I, II, and III were 10.4%, 24.4%, and 47.6%, respectively, and 93 cases (17.6%) were missing. Revised International Staging System (R-ISS) stage I, II, and III were 5.5%, 27.0%, 23.1%, respectively, and 235 cases (44.4%) missed this data. Among the 98 NDMM patients in the Third Xiangya Hospital, Central South University, Durie-Salmon (DS) stage missing 2.0%, ISS stage missing 12.3%, and R-ISS stage missing 12.3%.Treatment: Among the 529 patients,475 received treatment, the rate of treatment was 89.8%; 67.4% of the patients were able to complete four courses of chemotherapy at induction phase, 90.3% of the patients received proteasome inhibitor based combination chemotherapy regimen more than once, 67.2% received immunomodulator based regimen more than once, and 59.8% of the patients received proteasome inhibitor and immunomodulator based combination chemotherapy regimen more than once. Curative: Overall response rate (ORR) and high quality response rate (HQR) of the 4-course group were better than those of the 2-course group (ORR: 85% vs 65%, P=0.006; HQR: 68.3% vs 24.0%, P<0.001). The HQR of the standard chemotherapy group was better than that of the non-standard chemotherapy group (65.1% vs 48.2%, P=0.035). Adverse reactions during treatment included hematologic toxicity (17.5%), peripheral neuropathy (24.8%), gastrointestinal adverse events (23.8%), pulmonary infection (25.9%), herpes zoster (4.6%), and venous thrombotic events (1.7%).@*CONCLUSIONS@#In 2019, the missed diagnosis rate of MM patients was high, the medium age of diagnosis was older, and the accuracy of patient diagnosis was not high. There is a great difference among medical centers, especially in the stage and risk stratified, nearly half of NDMM patients are not diagnosed with R-ISS stage; the lack of cytogenetic data needs to be supplemented by follow-up studies. A high proportion of patients with NDMM present with bone pain and anemia.Patients received treatment have higher use of chemotherapy regimens containing proteasome inhibitors and/or immunomodulators, but there is a significant gap among different medical centers, and standardized treatment needs to be strengthened. The safety during chemotherapy is controllable.

ABSTRACT

OBJECTIVE@#To test the hypothesis that β -glucan enhances protective qi (PQi), an important Chinese medicine (CM) concept which stipulates that a protective force circulates throughout the body surface and works as the first line of defense against "external pernicious influences".@*METHODS@#A total of 138 participants with PQi deficiency (PQD) were randomized to receive β -glucan (200 mg daily) or placebo for 12 weeks. Participants' PQi status was assessed every 2 weeks via conventional diagnosis and a standardized protocol from which a PQD severity and risk score was derived. Indices of participants' immune and general health status were also monitored, including upper respiratory tract infection (URTI), saliva secretory IgA (sIgA), and self-reported measures of physical and mental health (PROMIS).@*RESULTS@#PQi status was not significantly different between the β -glucan and placebo treatment groups at baseline but improved significantly in the β -glucan (vs. placebo) group in a time-dependent manner. The intergroup differences [95% confidence interval (CI)] in severity score (scale: 1-5), risk score (scale: 0-1), and proportion of PQD participants (%) at finish line was 0.49 (0.35-0.62), 0.48 (0.35-0.61), and 0.36 (0.25-0.47), respectively. Additionally, β -glucan improved URTI symptom (scale: 1-9) and PROMIS physical (scale: 16.2-67.7) and mental (scale: 21.2-67.6) scores by a magnitude (95% CI) of 1.0 (0.21-1.86), 5.7 (2.33-9.07), and 3.0 (20.37-6.37), respectively, over placebo.@*CONCLUSIONS@#β -glucan ameliorates PQi in PQD individuals. By using stringent evidence-based methodologies, our study demonstrated that Western medicine-derived remedies, such as β -glucan, can be employed to advance CM therapeutics.

ABSTRACT

BACKGROUND@#Lung cancer is still the malignant tumor with the highest morbidity and mortality in China. Lung adenocarcinoma is the most common subtype, and the number of lung cancer presenting as mixed ground glass nodule (mGGN) in imaging is gradually increasing. Visceral pleural invasion (VPI) is an important factor affecting the prognosis of mGGN type lung adenocarcinoma. The aim of the study is to explore and analyze the risk factors for VPI in mGGN type lung adenocarcinoma.@*METHODS@#From November 2016 to November 2019, 128 patients with mGGN lung adenocarcinoma underwent radical surgical resection in the First Affiliated Hospital of Nanjing Medical University. Their clinical data, including imaging, pathological and biological features, were collected and analyzed retrospectively. There were 40 males and 88 females, aged 60.3±9.3 years ranging from 30 to 81 years. Single factor Chi-square test and multivariate Logistic regression were used to analyze the risk factors of VPI in mGGN type lung adenocarcinoma.@*RESULTS@#Among 128 mGGN patients who met the inclusion criteria, 57 cases were pathologically confirmed with pleural invasion. Between the VPI (+) and VPI (-) group (P<0.05), there were significant differences in gender, maximum diameter of solid component, consolidation tumor ratio (CTR), spicule sign, history of lung disease, family history of hypertension, relation of lesion to pleura (RLP), coursing relationship between bronchi and nodules. In multivariate Logistic regression analysis, RLP (OR=3.529, 95%CI: 1.430-8.713, P=0.006) and coursing relationship between bronchi and nodules (OR=3.993, 95%CI: 1.517-10.51, P=0.005) were found to be independent risk factors for VPI (P<0.05).@*CONCLUSIONS@#The possibility of VPI in m GGN lung adenocarcinoma should be evaluated by combining these parameters in clinical diagnosis and treatment. As independent risk factors, RLP and coursing relationship between bronchi and nodules are instructive to identify VPI in mGGN type lung adenocarcinoma.

ABSTRACT

Cancer-associated fibroblasts (CAFs) and tumor-infiltrating immune cells are the most essential components of the tumor microenvironment (TME). They communicate with each other in tumor microenvironment and play a critical role in tumorigenesis and development. CAFs are very heterogeneous and different subtypes of CAFs display different functions. At the same time, it can contribute to the regulation of the function of tumor-infiltrating immune cells and eventually result in the carcinogenesis, tumor progression, invasion, metastasis and other biological behaviors of tumors by producting various growth factors and cytokines etc. Based on the current research results at home and abroad, this paper reviews the recent research progress on the regulation of CAFs on infiltrating immune cells in tumor microenvironment.

ABSTRACT

BACKGROUND@#At present, the research progress of targeted therapy for epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) gene mutations in lung adenocarcinoma is very rapid, which brings new hope for the treatment of advanced lung adenocarcinoma patients. However, the specific imaging and pathological features of EGFR and ALK gene mutations in adenocarcinoma are still controversial. This study will further explore the correlation between EGFR, ALK gene mutations and imaging and pathological features in invasive lung adenocarcinoma.@*METHODS@#A total of 525 patients with lung adenocarcinoma who underwent surgery in our center from January 2018 to December 2019 were included. According to the results of postoperative gene detection, the patients were divided into EGFR gene mutation group, ALK gene mutation group and wild group, and the EGFR gene mutation group was divided into exon 19 and exon 21 subtypes. The pathological features of the mutation group and wild group, such as histological subtype, lymph node metastasis, visceral pleural invasion (VPI) and imaging features such as tumor diameter, consolidation tumor ratio (CTR), lobulation sign, spiculation sign, pleural retraction sign, air bronchus sign and vacuole sign were analyzed by univariate analysis and multivariate Logistic regression analysis to explore whether the gene mutation group had specific manifestations.@*RESULTS@#EGFR gene mutation group was common in women (OR=2.041, P=0.001), with more pleural traction sign (OR=1.506, P=0.042), and had little correlation with lymph node metastasis and VPI (P>0.05). Among them, exon 21 subtype was more common in older (OR=1.022, P=0.036), women (OR=2.010, P=0.007), and was associated with larger tumor diameter (OR=1.360, P=0.039) and pleural traction sign (OR=1.754, P=0.029). Exon 19 subtype was common in women (OR=2.230, P=0.009), with a high proportion of solid components (OR=1.589, P=0.047) and more lobulation sign (OR=2.762, P=0.026). ALK gene mutations were likely to occur in younger patients (OR=2.950, P=0.045), with somking history (OR=1.070, P=0.002), and there were more micropapillary components (OR=4.184, P=0.019) and VPI (OR=2.986, P=0.034) in pathology.@*CONCLUSIONS@#The EGFR and ALK genes mutated adenocarcinomas have specific imaging and clinicopathological features, and the mutations in exon 19 or exon 21 subtype have different imaging features, which is of great significance in guiding the clinical diagnosis and treatment of pulmonary nodules.

ABSTRACT

Objective To evaluate the clinical efficacy of liver transplantation in children with Alagille syndrome (ALGS). Methods Clinical data of 12 children with ALGS were collected and retrospectively analyzed. Clinical characteristics of children with ALGS, pathological characteristics of liver tissues, characteristics of liver transplantation, postoperative complications and follow-up of children with ALGS were analyzed. Results JAG1 gene mutation and typical facial features was present in all 12 children. Jaundice was the most common initial symptom, which occurred at 7 (3, 40) d after birth. Upon liver transplantation, the Z scores of height and body weight were calculated as -2.14 (-3.11, -1.83) and -2.32 (-3.12, -1.12). Five children developed severe growth retardation and 4 children with severe malnutrition. Eight of 12 children were diagnosed with cardiovascular abnormalities. Pathological examination showed that the lobular structure of the diseased livers of 4 children was basically maintained, and 8 cases of nodular liver cirrhosis in different sizes including 1 case of single early moderately-differentiated hepatocellular carcinoma. Three children were misdiagnosed with biliary atresia and underwent Kasai portoenterostomy. Eight children underwent living donor liver transplantation, three children underwent cadaveric donor liver transplantation (two cases of split liver transplantation and one case of cadaveric total liver transplantation), and one child underwent domino liver transplantation (donor liver was derived from a patient with maple syrup urine disease). during the follow-up of 30.0(24.5, 41.7) months, the survival rates of the children and liver grafts were both 100%. During postoperative follow-up, the Z scores of height and body weight were calculated as -1.24 (-2.11, 0.60) and -0.83 (-1.65, -0.43), indicating that the growth and development of the children were significantly improved after operation. Conclusions Liver transplantation is an efficacious treatment for children with ALGS complicated with decompensated cirrhosis, severe itching and poor quality of life. For children with ALGS complicated with cardiovascular abnormalities, explicit preoperative evaluation should be delivered, and consultation with pediatric cardiologists should be performed if necessary.

After corresponding treatment ,the apoptotic rate ,release of lactate dehydrogenase (LDH),malondialdehyde(MDA)level,the activity of superoxide dismutase (SOD),the level of tumor necrosis factor α(TNF-α),interleukin 1β(IL-1β)and interleukin- 6(IL-6), mRNA and protein expression of Rnd 3 and NF-κB subunit p65(NF-κB p65),the expression of aspartate proteolytic enzyme 3 (Cleaved Caspase- 3)protein and Cleaved Caspase- 9 protein were detected. RESULTS Different concentrations of acteoside could reduce the apoptotic rate of H/R-induced H 9c2 cardiomyocyte,the protein expressions of Cleaved Caspase- 3 and Cleaved Caspase-9,mRNA and protein expressions of NF-κB p65,the levels of LDH release and MDA ,TNF-α,IL-1β and IL-6,while increase the activity of SOD and mRNA and protein expressions of Rnd 3(P<0.05),in a dose-dependent manner. Overexpression of Rnd 3 could decrease the apoptotic rate of H 9c2 cardiomyocyte,protein expressions of NF-κB p65,Cleaved Caspase- 3 and Cleaved Caspase- 9, the levels of LDH release , MDA, TNF-α,IL-1β and IL-6,while increase the protein expression of Rnd 3 and the activity of SOD (P<0.05). The inhibition overexpression of Rnd 3 could weaken the inhibitory effects of acteoside on H/R-induced apoptosis of H 9c2 cardiomyocyte, oxidative stress and inflammatory reaction (P<0.05). CONCLUSIONS Acteoside could regulate Rnd 3/NF-κ B pathway by promoting the expression of Rnd 3 and inhibiting the expression of NF-κB p65,inhibit cardiomyocyte apoptosis ,oxidative stress and inflammation reaction so as to relieve the H/R-induced cardiomyocyte damage.

ABSTRACT

This paper aims to develop folic acid-modified paclitaxel nanocrystals (PTX NC@FA) with good stability, high drug loading and tumor cell targeting for endoscopic injection for preoperative local chemotherapy of gastric cancer. PTX NC@FA was prepared by the "bottom-up" followed by ultrasonic to study its morphology, particle size, ζ-potential, drug loading, folic acid-modified phospholipid (FA-DSPE-PEG2000) content, crystalline characteristics, stability, in vitro release, cytotoxicity against human gastric cancer cell line SGC-7901, and anti-tumor effect in two different tumor sizes (tumor volume 100 mm3 or 300 mm3) after single peri-tumor injection in a murine subcutaneous SGC-7901 tumor model. Animal experiments were approved by the Experimental Animal Ethics Committee of the School of Pharmacy, Fudan University. The resulting PTX NC@FA was of short rod-like shape, average particle size 175.3 ± 2.5 nm (PDI 0.17 ± 0.02), ζ- potential -2.5 ± 0.2 mV, PTX loading (28.23 ± 0.74) % (w/w) and FA-DSPE-PEG2000 content (4.40 ± 0.60) % (w/w). The size of the PTX NC@FA remained unchanged for 4 days in phosphate buffer with or without serum. Cellular growth inhibition effect on SGC-7901 showed the superiority of PTX NC@FA over nanocrystals without FA modification. PTX NC@FA inhibited tumor growth more efficiently than both nanocrystals without FA modification and commercially available paclitaxel injection (Taxol) 12 days after peri-tumor injection. For model tumor with the volume of 100 mm3, tumors of all animals in the PTX NC@FA group disappeared completely. For model tumor with the volume of 300 mm3, tumors of 3 animals in the PTX NC@FA group completely disappeared and tumors of the rest 4 animals also became significantly smaller with a tumor volume inhibition rate of 90%. PTX NC@FA showed good potential for preoperative chemotherapy of increase the chances of function preserving gastrectomy and improve the quality of life of patients.

ABSTRACT

@#Objective    To analyze the results and rationality of the lesion-focused strategy with subsegment as the pulmonary anatomical unit for pulmonary nodules with a diameter of ≤2 cm which require surgery. Methods    Clinical data of 246 patients with pulmonary nodules who underwent surgery in the Department of Thoracic Surgery of The First Affiliated Hospital of Nanjing Medical University from January 2017 to October 2018 were retrospectively analyzed, including 76 males and 170 females, with an average age of 53.30±11.82 years. The patients were divided into four groups, a single segmentectomy group, a segmentectomy combined with adjacent subsegmentectomy group, a single subsegmentectomy group and a combined subsegmentectomy group, according to the different surgical approaches, to compare preoperative, intraoperative, and postoperative related data. Results    There was no perioperative death. Among the four groups, there was no statistical difference in gender (P=0.163), age (P=0.691), diameter of the nodule (P=0.743), longitudinal position of the nodule (depth ratio, P=0.831), postoperative pulmonary leakage (P=0.752), intraoperative blood loss (P=0.135), pathological type (P=0.951) or TNM stage (P=0.995); there were statistical differences in transverse position of the nodule (P<0.001) and number of subsegments involved (P<0.001). The results of multivariate logistic regression analysis showed that compared with combined subsegmentectomy, the odds ratio (OR) of the lung nodule in segmentectomy combined with adjacent subsegmentectomy as intersegment nodules was 5.759 (95%CI 1.162 to 28.539, P=0.032). Conclusion     The surgical strategy of lesion  focused and subsegment as anatomical unit is safe and feasible for surgical treatment of pulmonary nodules with diameter ≤2 cm. The transverse position of the nodules is an important factor affecting the choice of surgical method for the middle and lateral nodules with a diameter of ≤2 cm, and the longitudinal location of the nodule is not an influencing factor. For nodules in inner zone, the diameter also is one of the factors influencing the choice of surgical method.

ABSTRACT

Diabetic foot wound repair is a challenging issue in clinical practice. Due to the influence of multiple factors including the damage and regeneration failure of local tissue, the impaired pathways of wound repairing through blood vessels and nerve nutrition, and disorders of a variety of cellular factors, traditional treatment methods are often difficult to achieve good therapeutic effects. Stem cells are a type of cells with potentials of multidirectional differentiation, which also possess functions such as regulating immunity and paracrine to facilitate the comprehensive wound repair, so they have promising application prospect at present for the treatment of diabetic foot wounds. Because the relevant parameters of stem cell treatment are in the exploratory phase, there were no standardized data. This paper reviews the application of stem cells in the research of diabetic foot wound treatment over the past 6 years, analyzing and summarizing the contents in focused aspects including the types and sources of stem cells, effects of donor age and gender on stem cells, mode of administration, transplantation survival rate and safety, which may provide a reference for further application of stem cells in the clinical treatment of diabetic foot wound.

ABSTRACT

To assess the treatment effectiveness of vital inflamed pulp therapy (VIPT) in immature permanent teeth with irreversible pulpitis and apical periodontitis. The faculty members in the Department of Pediatric Dentistry, the Ninth People's Hospital were invited to submit consecutive VIPT cases from June 2015 to June 2016 (follow-up periods>12 months). The cases were retrospectively reviewed, clinical symptoms and radiographic changes in periapical radiolucency were evaluated, meanwhile, the data of radiographic changes such as apical diameter and root length were calculated and analyzed with ANOVA. Totally thirteen submitted patients/cases were included (6 males and 7 females) in the present study,. The average age of patients was (9.9±1.4) years old. The average follow-up time was (26.5±6.8) months (17-37 months). At the 12-month visit, all 13 treated teeth survived, 9 out of 11 teeth with apical periodontitis showed normal radiographic manifestation. At the 3, 6 and 12 months visits, the within-case percentage changes in apical diameter were (8.0±5.1)%, (24.1±9.1)% and (70.3±10.7)%, respectively, while the within-case percentage changes in root length were (11.4±9.8)%, (14.5±9.8)% and (27.4±14.2)%, respectively. There were statistically significant differences in the changes of apical diameter (F=18.80, P<0.001) and root length (F=4.64, P=0.047) from the preoperative time to the postoperative follow-ups. VIPT might improve clinical outcomes, even achieve continued root development. VIPT can be an option in treating immature teeth with irreversible pulpitis and apical periodontitis.

ABSTRACT

Objective: To analyze mortality and its trend of chronic respiratory diseases (CRD) in China from 1990 to 2019. Methods: Based on the provincial results of China from the 2019 Global Burden of Disease (GBD) study, the average annual percent change (AAPC) of standardized mortality rates of different CRDs were analyzed by using Joinpoint 4.8.0.1, and the age-standardized mortality rate of CRD was calculated by using the GBD 2019 world standard population. Based on the comparative risk assessment theory of GBD, the attributable deaths due to 12 CRD risk factors were estimated, including smoking, indoor air pollution, occupational gas exposure, particulates and smog exposure, environmental particulate pollution, low temperature, passive smoking, ozone pollution, occupational exposure to silica, occupational asthma, high body mass index, high temperature and occupational exposure to asbestos. Results: From 1990 to 2019, the number of deaths and standardized mortality of chronic obstructive pulmonary disease (COPD) showed a downward trend (P<0.001). The number of COPD deaths decreased from 1 244 000 (912 000 - 1 395 000) in 1990 to 1 037 000 (889 000 - 1 266 000) in 2019. AAPC=-0.9% (95%CI: -1.5% - -0.3%), P<0.001; The standardized mortality rate decreased from 217.9/100 000 (163.3/100 000 - 242.0/100 000) in 1990 to 65.2/100 000 (55.5/100 000 - 80.1/100 000) in 2019. AAPC= -4.2% (95%CI:-5.2% - -3.2%), P<0.001. The number of deaths from asthma decreased from 40 000 (30 000 - 58 000) in 1990 to 25 000 (20 000 - 31 000) in 2019. AAPC=-2.0% (95%CI: -2.6% - -1.4%), P<0.001; The standardized mortality rate of asthma decreased from 6.4/100 000 (4.7/100 000 - 9.5/100 000) in 1990 to 1.5/100 000 (1.2/100 000 - 1.9/100 000) in 2019. AAPC=-5.1% (95%CI: -5.8% - -4.4%), P<0.001. The number of pneumoconiosis deaths decreased from 11 000 (8 000 - 14 000) in 1990 to 10 000 (8 000 - 14 000) in 2019, AAPC=-0.2%(95%CI:-0.4% - 0.1%), P=0.200; The standardized mortality rate of pneumoconiosis decreased from 1.4/100 000 (1.0/100 000 - 1.7/100 000) in 1990 to 0.5/100 000 (0.4/100 000 - 0.7/100 000) in 2019. AAPC=-3.1% (95%CI: -3.4% - -2.8%), P<0.001. The number of deaths from pulmonary interstitial diseases and pulmonary sarcoidosis increased from 3 000 (3 000 - 6 000) in 1990 to 8 000 (6 000 - 10 000) in 2019, AAPC=3.5% (95%CI: 2.7% - 4.2%), P<0.001; The corresponding standardized mortality rate changed little from 1990 to 2019, and AAPC was not statistically significant.The age-standardized mortality rates of different CRDs were higher in men than those in women. In 1990 and 2019, the mortality rates of COPD, asthma, pneumoconiosis and interstitial pulmonary disease and pulmonary sarcoidosis increased with age. In 2019, the population attributable fractions (PAFs) for smoking, environmental particulate pollution, occupational gas exposure, particulate and smog exposure, low temperature exposure and passive smoking were 71.1% (68.0% - 74.3%), 24.7% (20.1% - 30.0%), 19.3% (13.0% - 25.4%), 15.7% (13.6% - 18.3%) and 8.8% (4.5% - 13.1%) respectively in men, and the PAFs for environmental particulate pollution, smoking, low temperature exposure, occupational gas exposure, particulate and smog exposure, and passive smoking were 24.1% (19.6% - 29.3%), 21.9% (18.7% - 25.2%), 16.4% (14.0% - 19.2%), 15.6% (10.2% - 21.1%) and 14.7% (7.9% - 21.3%) respectively in women. Conclusions: During 1990-2019, the overall death level of CRD decreased significantly in China, but it is still at high level in the world. Active prevention and control measures should be taken to reduce the death level caused by CRD.
