ABSTRACT

Objective@#To verify the applicability of the theory of planned behavior(TPB) in the physical exercise behaviors of rural adolescents in Sichuan Province, and to explore the possible influencing factors of physical exercise behaviors, and to provide a theoretical basis for further effective intervention measures.@*Methods@#A total of 2 302 students were selected from grade seven and grade ten of two rural middle schools in Zizhong, Sichuan Province. The survey was conducted with a structured questionnaire. Using TPB as the research framework and basis, the structural equation model was constructed for analysis.@*Results@#Lack of physical exercise was 1 527(66.3%).Physical exercise behavior was statistically different among schools, grades(t=-7.40,-2.90,10.90,P<0.05), and genders. Based on TPB, the structural equation model was established and corrected to obtain the revised model, and the fitting index GFI=0.93, CFI=0.94, NFI=0.94, TLI=0.93, IFI=0.94,RMSEA=0.07, indicating the model fitted good. Exercise intention directly affected exercise behaviors. The standardized effect was 0.45(95%CI=0.39-0.52). Subjective norms and perceived power were the main two mediators of the relationship between value evaluation and exercise intention. The standardized effect values were 0.66(95%CI=0.57-0.73), 0.23(95%CI=0.16-0.93)(P<0.01).@*Conclusion@#There is serious lack of physical exercise in rural adolescents in Sichuan Province. TPB has a good applicability for physical exercise in rural adolescents in Sichuan Province. Subjective norm is the most important factors to promote exercise intentions.

ABSTRACT

@#AIM: To investigate the effect and safety of endoscopic-assisted RS silicone intubation for congenital nasolacrimal duct obstruction after failed probing in children, in order to guide the clinical application.<p>METHODS: Retrospective case series. Totally 158 children(158 eyes)with congenital nasolacrimal duct obstruction who were failed probing in our hospital from September 2016 to September 2019 were selected as the research subjects. All patients underwent endoscopic-assisted RS silicone intubation. Regular follow-up was performed 1, 3, and 6mo after surgery. Observe the children's gender, age, treatment history, presence or absence of discharge before surgery; treatment effect; complications; types of nasolacrimal duct obstruction. Spearman's correlation coefficient calculation and analysis of the relationship between ages, times of probing and operation efficiency, Fisher's exact probability test for the operation efficiency of different types of nasolacrimal duct obstruction, and chi square test for the operation efficiency of presence or absence of discharge.<p>RESULTS: The total effective rate was 89.9%(142/158). The effective rate of surgery tends to decrease with age(Spearman's correlation coefficient <i>rs</i>= -1.000, <i>P</i><0.01). The effective rate of surgery showed a downward trend with the increase of the times of probing(Spearman's correlation coefficient <i>rs</i>= -1.000, <i>P</i><0.01). The efficiency of membranous nasolacrimal duct obstruction surgery is higher than that of complex nasolacrimal duct obstruction, and the difference is statistically significant(<i>P</i><0.05). It cannot be considered that there is a statistically significant difference in the effectiveness of the operation between the two symptoms with or without discharge(<i>P</i>>0.05). The main complications were: false passage formation(16 eyes, 10.1%), loss of tube(14 eyes, 8.9%), red eyes and irritated tears(18 eyes, 11.4%), punctums tissue adhesion(3 eyes, 1.9%), punctum granuloma formation(1 eye, 0.6%).<p>CONCLUSION: Endoscopic-assisted RS silicone intubation has a higher effective rate and better safety in the treatment of congenital nasolacrimal duct obstruction after failed probing in children. The effective rate of surgery decreases with age, and decreases with the increase of the times of probing. Membranous nasolacrimal duct obstruction is more effective than complicated nasolacrimal duct obstruction.

ABSTRACT

Objective:To develop a novel method for detection of genomic RNA of 2019-nCoV with reverse-transcription thermophilic helicase-dependent amplification (tHDA) and lateral flow dipsticks.Methods:This study included 143 PCR-negative nucleic acid specimens and 20 PCR- positive nucleic acid specimens collected from patients from January to April 2020 at Institute of Clinical Laboratory, Jinling Hospital. 5 pairs of primers were designed for conserved sequence of both gene N and E of 2019-nCoV, and the amplicons were analyzed by gel electrophoresis to screen out the most efficient primers. High level (5×10 5 copies/ml) and low level (5×10 2 copies/ml) templates were amplified, and lateral flow dipsticks (LFD) were used to detect amplification products. The amplification time and visualization time were optimized to visualize the results, and the optimal tHDA-LFD reaction system was established. Simulated specimens with low, medium, and high concentrations were detected for 15 times, and precision was assessed. The limit of detection was evaluated using tenfold serial dilutions of 2019-nCoV in contrived samples. To evaluate the cross-reactivity, six samples of respiratory viruses, including influenza A virus, influenza B virus, human adenovirus, human respiratory syncytial virus, human parainfluenza virus and coronavirus 229E were tested using this assay. The tHDA-LFD assay was performed to detect 2019-nCoV in 163 clinical specimens stored in our laboratory. The clinical diagnostic efficacy was determined. Results:The established RT-tHDA one-step method combined with LFD was adopted, which could be conducted within 60 min and was reproducible with good precision, showing 100% positive concordance rate. The assay showed no cross reaction with other six human respiratory pathogens. The limit of detection of the RT-tHDA assay was 5×10 2 copies/ml for both N and E genes detected by LFD. The diagnostic efficacy evaluation showed that the sensitivity of the method was 95.00%(19/20), and the specificity was 100.00%(143/143). The positive predicted value of the method was 100.00% (19/19)and the negative predicted value was 99.31%(143/144). Compared with real-time RT-qPCR assay, it showed Kappa value of 0.971 ( P<0.0001). Conclusion:The proposed tHDA-LFD assay is a rapid and visualized method to detect 2019-nCoV.

ABSTRACT

Objective:To explore the effect of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on the aerobic capacity of middle-aged and elderly patients with type 2 diabetes.Methods:A total of 95 patients with type 2 diabetes (aged 45 to 70 years) were randomly divided into an HIIT group ( n=35), an MICT group ( n=35) and a sedentary control group (CON group) ( n=25). All of the subjects maintained their daily habits, but the HIIT and MICT groups performed their corresponding exercise using a bicycle ergometer 4 times/week for 8 weeks. Before and after the 8 weeks, each subject′s maximum oxygen uptake (VO 2max) was measured using a graded exercise test. Results:Eighty-three of the subjects (87.4%) completed the study. The follow-up loss rate in the HIIT group was 13% and in the MICT group it was 14%. After the intervention, the average VO 2max had increased by (11.5±2.3)% in the HIIT group and (8.1±1.9)% in the MICT group, a difference which is not significant. Conclusion:Either HIIT or MICT is feasible, well tolerated, safe and effective for improving the aerobic capacity of middle-aged and elderly patients with type 2 diabetes.

ABSTRACT

Objective:To explore the clinicalfactors related to allograft fibrosis after pediatric liver transplantation.Methods:The clinical data were respectively analyzed for 94 pediatric recipients from January 2013 to December 2016 at Tianjin First Central Hospital.The Patients were assigned into fibrotic and non-fibrotic groups based upon the results of protocol liver biopsies. Univariate and multivariate Logistic regression analyses were performed for examining the risk factors of fibrosis after pediatric livertransplantation. Then Logistic regression model was established to obtain the predicted value of combined predictive factors.Thereceiver operating characteristic curve (ROC) was conducted to evaluate the predictive value of combined predictive factors.Results:A total number of 54(57.5%) patients occurred fibrosis among the 94 patients. There weresignificant differences in cold ischemia time (Z=2.094), warm ischemia time (Z=2.421), biliary stricture( χ2=4.560), drug-induced liver injury ( χ2=7.389), hepatic artery thrombosis and rejection ( χ2=6.955)between two groups ( P<0.05). Logistic regression analysis showed that cold ischemia time (OR=1.003, 95%CI: 1.000~1.007, P=0.044), biliary stricture(OR=6.451, 95%CI: 1.205~33.295), rejection(OR=2.735, 95%CI: 1.057~7.077)and drug-induced liver injury (OR=4.977, 95%CI: 1.207~20.522, P=0.026) were independent risk factors for fibrosis 5 years after liver transplantation. The area under the ROC curve was 0.786(95%CI: 0.691~0.881), for predicting patient outcome.If using 0.311as a cutoff Value, the sensitivity was 90.70%, and the specificity was 60.00%. However, through the ROC curve comparison, there was statistical significance between combined predictive factors and the other independent risk factors ( P>0.05). Conclusions:The incidence of fibrosis 5 years after pediatricliver transplantation is 57.5%. Prolonged cold ischemia time, biliarystricture, rejectionand drug-induced liver injury after liver transplantation are independent risk factors for fibrosis 5 years after pediatric liver transplantation.And the combined predictive factors have a high predictive value forallograftfibrosis.

ABSTRACT

Objective:To explore the reference interval of urinary iodine concentration(UIC)/urinary creatinine(UCr) ratio evaluating the iodine nutritional status in early pregnancy women.Methods:A reference interval of UIC/UCr ratio was determined among 5 609 early pregnant women with normal thyroid function, negative thyroid autoantibodies, and no history of diseases or taking drug that may affect thyroid function. Then we verified the reliability of this reference interval in a group of 7 514 women in early pregnancy.Results:We determined the UIC/UCr ratio of 75-149 μg/g as the reference interval. In the reference interval, thyroglobulin antibody(TgAb), thyroid peroxidase antibody(TPOAb), and thyroglobulin(Tg) were all at lower levels, and the overall distributions were approximately U-shaped. The prevalence of thyroid dysfunction, the positive rates of antibodies and the proportion of Tg>40 μg/L were the lowest within the reference interval, while higher on both sides of the interval.Conclusion:The reasonable reference interval of the UIC/UCr ratio in iodine-sufficient regions is 75-149 μg/g in early pregnerty women.

ABSTRACT

Objective:To investigate the correlation between anterior cruciate ligament injury and the bone contusion in the posterior of tibial plateau and the risk factors of it.Methods:Data of patients with knee trauma who came to our hospital from Oct. 2017 to Nov. 2019 were retrospectively analyzed. There are 100 males and 55 females with an average age of 40.0±10.6 years (range, 18-60). Bone contusion in the posterior tibial plateauand anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament, lateral collateral ligament and fibula injury were evaluated through imaging data, and injury mechanism, age, sex and the side of injury were collected from medical records. The effect of events on bone contusion in the posterior of tibial plateau was analyzed.Results:Bone contusion occurred in 92 of the 155 patients (56 males and 36 females), with an average age of 39.6±10.5 years (range, 19-55 years). There were 45 cases on right knee and 47 cases on the left side. ACL injury: ACL was completely ruptured in 42 cases, partially ruptured in 34 cases, and had no injury in 16 cases. There were 18 cases with PCL injury, and 74 cases without any injury. There were 57 cases of non-contact injury, and 35 cases of contact injury. There were 57 cases with fibular head injury, and 35 cases without. There were 44 cases with MCL injury, and 48 cases without. There were 13 cases with LCL injury, and 79 cases without. ACL injury degree ( χ2=18.345, P<0.05) and the head of fibula ( χ2=5.495, P<0.05) injury were significantly different between the two groups. There was no significant difference in male ratio ( χ2=1.315, P>0.05), knee side ( χ2=0.880, P>0.05), injury mechanism ( χ2=3.467, P>0.05), age ( t=0.664, P>0.05), LCL ( χ2=0.010, P>0.05)、MCL ( χ2=0.029, P>0.05) and PCL ( χ2=0.161, P>0.05). ACL injury was an independent risk factor for bone contusion in the posterior of tibial plateau ( P<0.05) and the injury of fibula head was an independent risk factor for the formation of bone contusion in the posterior of tibial plateau ( P<0.05) according to logistic analysis. The possibility of bone contusion on the posterior tibial plateau in ACL complete injury was significantly greater than that of ACL partial injury ( OR=2.695, P=0.021). Conclusion:The injury of ACL and fibula head are independent risk factors for the bone contusion in posterior of tibial plateau; ACL complete injury is more likely to be associated with posterior tibial plateau bone contusion than ACL partial injury.

ABSTRACT

Objective:To discussed the diagnostic value of magnetic resonance cholangiopancreatography (MRCP), and the use of laparoscopic surgery in management of patients with choledochal cyst with extrahepatic bile duct anomaly.Methods:Of 330 consecutive patients who underwent laparoscopic choledochectomy at Guangzhou Women and Children's Medical Center from January 2010 to September 2018, there were 23 patients with extrahepatic bile duct anomaly. The data of these patients were retrospectively analyzed. There were 4 males and 19 females, with an average age of 3.2 (range 0.3~9.0) years. According to whether the extrahepatic bile duct anomaly was diagnosed by preoperative MRCP, these patients were divided into the preoperative MRCP diagnosis group and the preoperative MRCP undiagnosed group. The impact of MRCP in diagnosing bile duct anomaly to prevent bile duct injury, on operation time, hospital stay and the types of extrahepatic bile duct anomaly on outcomes of laparoscopic treatment were analyzed.Results:All the 23 patients with choledochal cysts complicated by extrahepatic bile duct anomaly were confirmed at surgery. The incidence of extrahepatic bile duct anomaly was 6.97% (23/330). There were 47.8% of type II AHD (11/23); 36.8% of type III AHD (7/23); 4.3% of type IV AHD (1/23); 17.4% (4/23) of the type with communication with accessory bile duct (CABD). The preoperative MRCP diagnosis group consisted of 14 patients, while the preoperative MRCP non-diagnosis group consisted of 9 patients, including 2 patients without MRCP. The diagnostic rate of MRCP in preoperative diagnosis of extrahepatic bile duct anomaly was 66.7%(14/21). The preoperative MRCP undiagnosed group, when compared with the preoperatives MRCP undiagnosed group, had a significantly higher bile duct injury rate [preoperative MRCP diagnosis group 7.1%(1/14), preoperative MRCP non-diagnosis group 55.6%(5/9)], and a significantly longer operation time [preoperative MRCP diagnosis group(232.6±10.0) min, preoperative MRCP undiagnosed group (278.9±22.45)min], (all P<0.05). Laparoscopic surgery was completed in 22 of 23 patients. One patient was converted to open surgery. AHD reconstruction was needed in 11 patients with type II AHD and 1 patient with type IV AHD. Seven patients with type III AHD did not require any surgical intervention for the anomaly. The 4 patients with CABD underwent simple ligation. Postoperative chyloperitoneum developed in 1 patient, who successfully responded to conservative treatment. Postoperative recovery was uneventful in the remaining patients. At a median follow-up of 2 years (range 1 to 5 years), no further complications, including intrahepatic bile duct dilatation and hepatic atrophy were detected. Conclusions:MRCP was effective in preoperative diagnosis of choledochal cysts with extrahepatic bile duct anomaly. It helped to decrease intraoperation injuries to bile duct anomalies. MRCP was also useful in classifying patients with extrahepatic bile duct anomaly to better preoperatively planning of surgical treatment strategies. Laparoscopic surgery could be completed in the majority of these patients with good postoperative results.

ABSTRACT

Objective:To evaluate the efficacy and safety of stereotactic ablative radiotherapy (SABR) in patients with pulmonary oligometastases.Methods:Clinical data of patients with pulmonary metastases treated with SABR from 2011 to 2018 were retrospectively analyzed. The local control rate (LCR) and overall survival (OS) were calculated by Kaplan- Meier method. log-rank test was used for univariate analysis and Cox’s regression model for multivariate analysis. Results:A total of 214 lung metastases were detected in 159 patients, and the median follow-up time was 43 months. The 1-, 3-and 5-year LCR were 90.1%, 73.9% and 65.8%, respectively. The 1-, 3-and 5-year OS were 73.8%, 43.6% and 11.9%, respectively. Univariate analysis showed that biological effective dose (BED)≥100 Gy was significantly correlated with LCR ( P=0.033). Cox’s multivariate analysis showed that BED and primary tumor source were the independent prognostic factors of LCR ( P=0.023, P=0.043). No>grade 3 adverse events were observed in all patients during treatment. Conclusions:SABR is a safe and effective treatment of lung oligometastases. SABR should be actively aD ministered for pulmonary oligometastases, especially for those with lesions from lung cancer and the radiation dose should be selected as BED ≥100 Gy.

ABSTRACT

Objective:To understand the epidemiological characteristics of brucellosis in non-occupational population reported in Hangzhou, and provide basis for diagnosis and further prevention and control of brucellosis in non-occupational population.Methods:The basic information, epidemiological characteristics, clinical characteristics and laboratory test data of brucellosis patients reported in Hangzhou from 2008 to 2019 were collected retrospectively. The data were obtained from the case questionnaire of confirmed brucellosis and annual report of brucellosis prevention and control work of Hangzhou Center for Disease Control and Prevention over the years. The epidemiological characteristics, clinical characteristics and diagnosis of brucellosis in non-occupational population were analyzed.Results:From 2008 to 2019, 76 cases of brucellosis in non-occupational population were reported in Hangzhou, accounting for 34.23% (76/222) of the total reported brucellosis cases. In the 76 cases of brucellosis in non-occupational population, there were 47 males and 29 females, the ratio of male to female was 1.62∶1.00; the age was (47.37 ± 16.04) years old, ranging from 6 to 84 years old. The peak incidence of brucellosis in non-occupational population was from March to May, accounting for 59.21% (45/76); the main routes of infection were direct contact and digestive tract, accounting for 80.26% (61/76). The main clinical symptoms were fever (100.00%, 76/76), hyperhidrosis (73.68%, 56/76) and muscle and joint pain (69.74%, 53/76); the diagnosis time was 27 (14, 49) d, and the longest diagnosis time was 190 d. Among them, 39 cases were misdiagnosed, accounting for 51.32% (39/76). Sixty suspected Brucella strains were identified by routine culture of automatic blood culture apparatus in hospital laboratory, and 54 strains of Brucella melitensis were identified by typing, with a coincidence rate of 90.00%. The blood culture rate of patients from 2015 to 2019 (88.46%, 46/52) was significantly higher than that from 2008 to 2014 (58.33%, 14/24), the difference was statistically significant (χ 2=8.968, P < 0.05). Conclusions:From 2008 to 2019, the onset of brucellosis in non-occupational population is seasonal in Hangzhou, the infection mode is diverse, the clinical symptoms are not typical, and it is easy to be misdiagnosed. Blood culture for suspected brucellosis patients in high incidence season is conducive to the early diagnosis of brucellosis.

ABSTRACT

@#Objective    To summarize the clinical outcomes and experience of surgical treatment for patients with complete atrioventricular septal defect (CAVSD) above the optimal age for surgery. Methods    We retrospectively reviewed clinical data of 163 simple type CAVSD patients less than 7 years who underwent operations in Fuwai Hospital from 2002 to 2013. The patients were divided into a normal group (n=84, including 37 males and 16 females with an average age of 7.6±2.7 months) and an over-age group (n=79, including 30 males and 49 females with an average age of 34.6±19.6 months) according to whether the age was more than 1 year. Results    The average aortic cross clamp time (88.3±24.4 min vs. 106.1±35.4 min, P<0.001) and cardiopulmonary bypass time (123.6±31.1 min vs. 142.6±47.1 min, P=0.003) were statistically different between the two groups. During the follow-up period (the normal group 53.3±43.9 months, the over-age group 57.2±48.2 months), there was no statistical difference in all-cause mortality (10.7% vs. 8.9%, P=0.691), the incidence of moderate or severe left atrioventricular valve regurgitation (16.7% vs. 21.5%, P=0.430) and reintervention rate (3.6% vs. 0.0%, P=0.266) between the two groups. No left ventricular outflow tract obstruction and complete atrioventricular block occurred in both groups. Conclusion    For CAVSD children above the optimal age, rational surgical treatments can also achieve satisfying results.

ABSTRACT

Considering the adverse effects of nonimpacted third molars (N-M3s) on the periodontal health of adjacent second molars (M2s), the removal of N-M3s may be beneficial to the periodontal health of their neighbors. This study aimed to investigate the clinical, immunological, and microbiological changes of the periodontal condition around M2s following removal of neighboring N-M3s across a 6-month period. Subjects with at least one quadrant containing an intact first molar (M1), M2, and N-M3 were screened and those who met the inclusion criteria and decided to receive N-M3 extraction were recruited in the following investigation. M2 periodontal condition was interrogated before M3 extraction (baseline) and at 3 and 6 months postoperatively. Improvements in clinical periodontal indexes of M2s in response to their adjacent N-M3 removal, along with changes in inflammatory biomarkers among gingival crevicular fluid (GCF) and the composition of subgingival plaque collected from the distal sites of the M2s of the targeted quadrant were parallelly analyzed. Complete data of 26 tooth extraction patients across the follow-up period were successfully obtained and subsequently applied for statistical analysis. Compared to the baseline, the periodontal condition of M2s was significantly changed 6 months after N-M3 removal; specifically, the probing depth of M2s significantly reduced (P < 0.001), the matrix metalloproteinase (MMP)-8 concentration involved in GCF significantly decreased (P = 0.025), and the abundance of the pathogenic genera unidentified Prevotellaceae and Streptococcus significantly decreased (P < 0.001 and P = 0.009, respectively). We concluded that N-M3 removal was associated with superior clinical indexes, decreased GCF inflammatory biomarkers, and reduced pathogenic microbiome distribution within the subgingival plaque. Although the retention or removal of N-M3s continues to be controversial, our findings provide additional evidence that medical decisions should be made as early as possible or at least before the neighboring teeth are irretrievably damaged.

ABSTRACT

Aiming at the problem of timeliness of CBCT reconstruction, a CBCT fast short scan reconstruction method is proposed. At the same time, the image reconstruction process in which a new attenuation compensation algorithm is applied to improve image quality. When performing FDK three-dimensional reconstruction of a single-frame acquisition image, the Parker-weighted image is calculated in real time, and a new attenuation compensation algorithm is applied in the back projection process to complete the short scan Parker-weighted reconstruction. This method simulates the CBCT synchronous acquisition and reconstruction process by establishing collection and reconstruction threads. Under the premise of satisfying the reconstruction quality, the reconstruction can be completed within 1 to 2 seconds after the patient collection is completed, which achieves the purpose of real-time.

ABSTRACT

Dry eye is a common ophthalmic disease caused by eye maladjustment due to meibomian gland dysfunction (MGD), which is often accompanied by symptoms such as increased tear film osmotic pressure and ocular surface inflammation. In the treatment of dry eye patients, dredging gland obstruction caused by meibomian gland secretion is an effective treatment method. Based on electrothermal effect and hyperelasticity of the silicone, an auxiliary treatment instrument for MGD is designed, which can improve the blood circulation of the glands through heat compress and massage to achieve the purpose of dredging the meibomian glands. The therapy device can display the temperature and pressure during the treatment in real time, so that the surgeon can grasp the progress of the treatment in real time. The therapy device constructs a user-oriented interactive interface based on parametric modeling method, which can be customized by 3D printing according to the user's eyeball geometric parameters. The designed therapeutic device was finally tested on New Zealand white rabbits. The experimental results show that the therapeutic device has significant effectiveness and safety, as well as clinical application prospects.

ABSTRACT

OBJECTIVE@#To analyze the influence of serum homocysteine (Hcy) levels to the prognosis of newly diagnosed multiple myeloma (MM) patients, and to explore related factors affecting the prognosis of the patients.@*METHODS@#The clinical pathological data of 180 newly diagnosed MM patients treated in our hospital from March 2013 to February 2015 were collected, and the patients were divided into high and low Hcy groups based on the median Hcy. The survival curves of the patients in the two groups were drawn to compare the differences of the survival; univariate and multivariate survival analysis was used to observe the influence of serum cysteine to the prognosis of newly diagnosed MM patients; the clinicopathological data of the patients with high and low Hcy in the two groups was compared, Pearson test was used to further analyzes the relationship between Hcy and different factors, and explores the related factors of Hcy affecting the prognosis of the patients.@*RESULTS@#The median survival times of patients in the high and low Hcy groups were 32 (5-59) and 41 (7-71) months, respectively. The 3-year survival rate of the patients in high Hcy group was significantly lower than those in low Hcy group, and the difference shows statistically significant (P<0.05). The results of univariate survival analysis showed that the OS of newly diagnosed MM patients whom with advanced age, high bone disease grade, high-level bone marrow plasma cell count, LDH, C-reactive protein, Cr, β@*CONCLUSION@#Serum Hcy level has a correlation trend with the survival of newly diagnosed MM, which is affected by factors such as Hb.
