ABSTRACT

Objective:To analyze the external quality control assessment results of fluoride testing laboratories in endemic disease prevention and control institutions nationwide from 2006 to 2023, investigate the quality control capabilities of these laboratories in various provinces, prefectures, cities, and counties nationwide, and ensure the accuracy and reliability of surveillance data on endemic fluorosis nationwide.Methods:Using retrospective analysis, the external quality control assessment results of all participating fluoride testing laboratories of national endemic disease prevention and control institutions from 2006 to 2023 were summarized and analyzed. The assessment results from 2006 to 2008 were tested for outliers using Grubbs method, homogeneity of variance using Cochran method, excluding the assessment data of unqualified laboratories, calculating the total mean and total standard deviation, Z-score method was used to test the assessment of laboratories, and statistical analysis and judgment were done when the result of │Z│ < 3. The assessment results from 2009 - 2023 were obtained from all laboratories. In 2010, two tests were conducted in the first and second half of the year, and the Z-ratio scores of each laboratory were calculated using robust statistics. When │Z│≤2, the assessment was qualified; when 2 < │Z│ < 3, the assessment was basically qualified; when│Z│≥3, the assessment was unqualified, and the consensus value came from all participating laboratories in the assessment.Results:From the beginning of quality control operation in 2006 to 2023, the number of laboratories participated in external quality control assessments had significantly increased. The number of laboratories participated in water fluoride assessment increased from 30 in 2006 to 1 277 in 2023, and the number of laboratories participated in urine fluoride assessment increased from 29 to 497. The number of laboratories participated in the brick tea fluorine assessment had increased from 43 in 2014 to 193 in 2023. The assessment results showed that when │Z│ < 3, the total qualified rate of fluoride external quality control in fluoride testing laboratories of national endemic disease control institutions was 95.2%, with the lowest being 87.1% (27/31) in 2008 and the highest being 100.0% (394/394) in 2014. When │Z│≤2, the total feedback pass rate was 88.4%, with the lowest being 79.3% (288/363) in the first half of 2010 and the highest being 99.5% (392/394) in 2014. The assessment results showed that when │Z│ < 3, the total pass rate of urine fluoride external quality control in fluoride testing laboratories of national endemic disease control institutions was 98.0%, with the lowest being 86.2% (25/29) in 2006 and 2007, respectively, and the highest being 100.0% (68/68) in 2014. When │Z│≤2, the total qualification rate was 93.7%, with the lowest being 86.5% (64/74) in the second half of 2010 and the highest being 100.0% (68/68) in 2014. The assessment results showed that when│Z│ < 3, the total pass rate of extra-fluoride quality control of brick tea in fluoride testing laboratories of national endemic disease control institutions was 95.4%, with the lowest being 85.0% (164/193) in 2023, and the highest being 100.0% (43/43, 51/51, 79/79) in 2014, 2015 and 2016, respectively. When │Z│≤2, the total pass rate was 89.2%, with the lowest being 72.7% (32/44) in 2017 and the highest being 100.0% (43/43) in 2014. From 2009 to 2023, there were a total of 21 provincial-level laboratories that passed the water fluoride detection assessment, including 3 provinces where all prefecture level and county-level laboratories were qualified. The assessment results of urinary fluorine showed that there were 11 qualified provincial-level laboratories and 1 prefecture-level laboratory. From 2014 to 2023, the assessment results of brick-tea fluorine showed that there were 5 provincial-level laboratories that passed the tea fluorine testing assessment and no prefecture-level laboratory.Conclusions:Conclusion: From 2006 to 2023, the number of fluoride testing laboratories participating in external quality control assessment has increased year by year, and most provincial, municipal and county-level laboratories have good fluoride testing capabilities, which can meet the testing needs of endemic disease prevention and monitoring. For some laboratories with problems, targeted rectification should be carried out to improve the quality of detection, in order to provide better technical support for the monitoring of endemic fluorosis areas.

ABSTRACT

【Objective】 To describe the distribution characteristics of knee and ankle joint range of motion and muscle atrophy related indexes in patients with Kashin-Beck disease (KBD) in Shaanxi Province so as to explore the correlation of knee and ankle joint range of motion (ROM) with muscle atrophy indexes and provide reference for clinical characteristics analysis of KBD patients. 【Methods】 To investigate the registered KBD patients from KBD areas in Shaanxi Province, we measured the general demographic data of the patients were collected and the ROM of the knee joint (flexion and extension), the ankle joint (dorsiflexion and plantar flexion), and the muscle atrophy related indexes such as the upper arm circumference, thigh circumference, calf circumference and grip strength. According to the population characteristics, i.e., gender, age, body mass index (BMI) and KBD grade, the median and quartile of joint ROM and muscle atrophy of KBD patients were reported, and then the differences in each index among different groups were analyzed. Partial correlation analysis was used to explore the correlation between indicators after controlling for variables such as gender, age and BMI. 【Results】 A total of 480 patients with KBD were investigated in this study, who consisted of 249 (51.9%) males and 231 (48.1%) females, with an average age of (63.10±7.32) years and an average BMI of (23.49±8.90) kg/m2. The knee flexion ROM, knee extension ROM, ankle dorsiflexion ROM and ankle plantar flexion ROM were [105.0 (95.0, 120.0)] °, [0.0 (-15.0, 0.0)] °, [5.0 (0.0, 15.0)] ° and [20.0 (15.0, 30.0)] °, respectively, in KBD patients in Shaanxi Province. The left thigh circumference, right thigh circumference, left calf circumference, right calf circumference, and upper arm circumference were [43.0 (40.0, 47.0)] cm, [43.0 (39.0, 47.0)] cm, [29.0 (27.0, 32.0)] cm, [29.5 (27.0, 32.0)] cm, [27.0 (25.0, 30.0)] cm, respectively. The left hand grip strength and right hand grip strength were [13.4 (9.5, 18.4)] kg and [13.9 (9.8, 18.2)] kg, respectively. With the increase of age, the extension range of the left and right knee joints of KBD patients showed a decreasing trend (H=31.499, 31.847; all P<0.001). The range of motion of bilateral knee flexion was higher in the normal BMI group than in the overweight or obese group, with statistically significant differences (H=7.753, 12.333; P=0.021, 0.002). The knee flexion, thigh circumference, and calf circumference of the left and right sides showed a decreasing trend under different KBD grades (H=14.345, 17.256, 8.000, 8.462, 8.558, 9.633; all P<0.05). Correlation analysis showed that knee flexion ROM was positively correlated with thigh circumference, calf circumference, and grip strength in patients with KBD (all P<0.05). There was a positive correlation between knee extension ROM and thigh circumference in patients with KBD (P<0.01). 【Conclusion】 The impaired joint ROM and muscle atrophy are serious in KBD patients in Shaanxi Province, and there is a correlation between joint motion and muscle atrophy.

ABSTRACT

Eggplant is an important horticultural crop and one of the most widely grown vegetables in the Solanaceae family. Eggplant fruit-related agronomic traits are complex quantitative traits with low efficiency and long cycle time for traditional breeding selection. With the rapid development of high-throughput sequencing technology and bioinformatics tools, genome-wide association study (GWAS) has shown great application potential in analyzing the genetic rules of complex agronomic traits related to eggplant fruits. This paper first reviews the progress of genome-wide association analysis in eggplant fruit shape, fruit color and other fruit-related agronomic traits. Subsequently, aiming at the problem of missing heritability, which is common in the genetic studies of eggplant quantitative traits, this paper puts forward the development strategies of eggplant GWAS in the future based on the hot spots of application of four GWAS strategies in the research of agronomics traits related to eggplant fruits. Lastly, the application of GWAS strategy in the field of eggplant molecular breeding is expected to provide a theoretical basis and reference for the future use of GWAS to analyze the genetic basis of various eggplant fruit-related traits and to select fruit materials that meet consumer needs.

ABSTRACT

Objective At present, the grading evaluation of patients with disorders of consciousness (DOC) is still a focus and difficulty in related fields. Electroencephalogram (EEG) can directly read and continuously reflect scalp electrical activity generated by brain tissue structure, with high temporal resolution. Auditory stimulation is easy to operate and has broad application prospects in clinical detection of DOC. The causal network can intuitively reflect the direction of information transmission through the causal relationship between time series, helping us better understand the information interaction between different regions of the brain of patients. This paper combines EEG and causal networks to explore the differences in brain functional connectivity between patients with unresponsive arousal syndrome (VS) and those with minimum state of consciousness (MCS) under auditory stimulation. MethodsA total of 23 DOC patients were included, including 11 MCS patients and 12 VS patients. Based on the Oddball paradigm, auditory naming stimulation was performed on DOC patients and EEG signals of DOC patients were synchronously collected. The brain functional networks were constructed using multivariate Granger causality method, and the differences in node degree, clustering coefficient, global efficiency, and causal flow of the brain networks between MCS patients and VS patients were calculated. The differences in network characteristics of patients with different levels of consciousness under auditory stimulation were compared from the perspective of cooperation between brain regions. ResultsThe causal connectivity between most brain regions in MCS patients was stronger than that in VS patients, and MCS patients had more brain network connectivity edges than VS patients. The average degree (P<0.05), average clustering coefficient, and global efficiency (P<0.05) of MCS patients under naming stimulation were higher than those of VS patients. The difference in out-degree between each node of VS patients was larger, and the difference in in-degree between each node of MCS patients was smaller. The difference in in-degree of MCS patients was more significant than that of VS patients, and the inflow and outflow of information in the brain functional network of MCS patients were stronger than those of VS patients. MCS and VS patients had differences of causal flow in the frontal and temporal lobes, the direction of information transmission in the parietal lobe and central region was not the same, and MCS patients had more electrodes as causal sources than VS patients. ConclusionThe information transmission ability of MCS patients is stronger than that of VS patients under auditory naming stimulation. Compared with VS patients, MCS patients have an increase in the number of electrode channels as the causal source, an increase in information output to other brain regions, and also an increase in the information output within brain regions, which may indicate a better state of consciousness in patients. MCS patients have more electrode channels for information output in the frontal lobe than VS patients, and the number of electrode channels for changing the direction of information transmission in the frontal lobe is the highest. The frontal lobe is closely related to the level of consciousness in patients with consciousness disorders. This study can provide a theoretical basis for the grading evaluation of consciousness levels in DOC patients.

ABSTRACT

The development of animal early embryos commences with the reprogramming of terminally differentiated gametes into totipotent zygotes following fertilization. During the initial stages of embryonic development, the transcriptional levels of zygotic genome remain silent and maternal gene products dominate the regulation of development. As embryonic development progresses, the maternal gene products undergo phased degradation while the zygotic genome gradually activates transcription, marking the transition from the maternal regulation to the zygotic genome regulation in early embryonic development, which is also referred to as the maternal-zygotic transition (MZT). Zygotic genome activation (ZGA) is a critical turning process in this transition, and its accurate occurrence is crucial for early embryonic development and cell fate decisions. However, the regulatory factors and molecular mechanisms of ZGA remain poorly understood. Studies have shown that ZGA varies greatly among different species and may be affected by a variety of regulatory factors such as DNA methylation, histone modification, non-coding RNA, chromatin remodeling and ZGA related factors. Here, we review the research progress of the above regulatory factors affecting ZGA, which can provide valuable insights for further investigations into the ZGA related mechanisms of early embryos.

ABSTRACT

ObjectiveExisting artificial vision devices can be divided into two types: implanted devices and extracorporeal devices, both of which have some disadvantages. The former requires surgical implantation, which may lead to irreversible trauma, while the latter has some defects such as relatively simple instructions, limited application scenarios and relying too much on the judgment of artificial intelligence (AI) to provide enough security. Here we propose a system that has voice interaction and can convert surrounding environment information into tactile commands on head and neck. Compared with existing extracorporeal devices, our device can provide a larger capacity of information and has advantages such as lower cost, lower risk, suitable for a variety of life and work scenarios. MethodsWith the latest remote wireless communication and chip technologies, microelectronic devices, cameras and sensors worn by the user, as well as the huge database and computing power in the cloud, the backend staff can get a full insight into the scenario, environmental parameters and status of the user remotely (for example, across the city) in real time. In the meanwhile, by comparing the cloud database and in-memory database and with the help of AI-assisted recognition and manual analysis, they can quickly develop the most reasonable action plan and send instructions to the user. In addition, the backend staff can provide humanistic care and emotional sustenance through voice dialogs. ResultsThis study originally proposes the concept of “remote virtual companion” and demonstrates the related hardware and software as well as test results. The system can not only achieve basic guide functions, for example, helping a person with visual impairment to shop in supermarkets, find seats at cafes, walk on the streets, construct complex puzzles, and play cards, but also can meet the demand for fast-paced daily tasks such as cycling. ConclusionExperimental results show that this “remote virtual companion” is applicable for various scenarios and demands. It can help blind people with their travels, shopping and entertainment, or accompany the elderlies with their trips, wilderness explorations, and travels.

ABSTRACT

Objective: To investigate the clinical effects of one-stage revision combined with intra-articular infusion of vancomycin in the treatment of chronic prosthetic joint infection (PJI) caused by Enterococcal. Methods: From May 2013 to June 2020,the clinical data of 9 patients (2 males and 7 females) with chronic Enterococcal PJI treated with one-stage revision using intra-articular infusion of vancomycin at Department of Orthopaedics,First Affiliated Hospital of Xinjiang Medical University were retrospectively analyzed,including 8 hips and 1 knee.A total of 9 patients with age of (63.9±11.7)years (range:43 to 76 years) were included, and the body mass index was (23.6±4.3)kg/m2 (range:18 to 30 kg/m2).There were 6 cases with antibiotic history and 5 cases with sinus tract.The joint fluid,infected tissue around the prosthesis and ultrasonic shock fluid of the prosthesis were collected during operation for microbial culture identification and drug sensitivity test.After thorough debridement of the infected site and removal of the infected prosthesis,a new prosthesis was implanted,then the drainage tube in the operation area was placed.After surgery,vancomycin(1.0 g,q12 h) was combined with intra-articular vancomycin(0.5 g,qd) in monomicrobial PJI,and vancomycin(1.0 g,q12 h) was combined with intra-articular vancomycin (0.5 g,qd) and imipenem/meropenem (0.5 g,qd),and the interval between the two drugs was 12 hours in polymicrobial PJI.Hip and knee functions were evaluated by Harris Hip Score or Knee Society Score(KSS),respectively.The comparison of hip function scores before and after operation was performed by paired t-test. Results: All patients were followed up for (60±39)months(range:24 to 110 months).Two cases were infected with Enterococcus faecium and 7 cases were infected with Enterococcus faecalis.There were 7 cases of monomicrobial infection and 2 cases of polymicrobial infection.Erythromycin(5/9),tetracycline(4/9),ciprofloxacin and β-lactam antibiotics(3/9) were the top three antibiotics in Enterococci resistance rate.The sensitive antibiotics for Enterococcal were vancomycin,linezolid and tigecycline.The average duration of intravenous antibiotics was (14±1)days (range:13 to 17 days),and the average duration of antibiotics in articular cavity was (15±2)days(range:11 to 20 days).Mean duration of oral antibiotic use after discharge was (2±1)months(range:1 to 3 months).One case of polymicrobial PJI treatment failed,with a failure rate of 1/9.At last follow-up,the Harris score of patients with hip PJI increased from (43±6)points to (84±6)points(t=-11.899, P<0.01). KSS score of knee function was improved from 33 point pre-operatively to 85 point post-operatively;overall function score was improved from 35 point pre-operatively to 80 point post-operatively.During the treatment,no formation of sinus tract of the hip joint caused by a catheter,skin necrosis at the knee puncture site or leakage of joint fluid;no complications such as deep vein thrombosis and pulmonary embolism occurred. Conclusions: One-stage revision combined with intra-articular infusion of vancomycin can achieve acceptable infection control rate and joint function in patients with chronic Enterococcus PJI.However,the treatment of polymicrobial PJI still needs to be further verified.

ABSTRACT

This paper aimed to investigate the effect of total flavonoids of buckwheat flower and leaf on myocardial cell apoptosis and Wnt/β-catenin/peroxisome proliferator-activated receptor γ(PPARγ) pathway in arrhythmic rats. SD rats were randomly divided into a control group, a model group, a low-dose(20 mg·kg~(-1)) group of total flavonoids of buckwheat flower and leaf, a medium-dose(40 mg·kg~(-1)) group of total flavonoids of buckwheat flower and leaf, a high-dose(80 mg·kg~(-1)) group of total flavonoids of buckwheat flower and leaf, a propranolol hydrochloride(2 mg·kg~(-1)) group, with 12 rats in each group. Except the control group, rats in other groups were prepared as models of arrhythmia by sublingual injection of 1 mL·kg~(-1) of 0.002% aconitine. After grouping and intervention with drugs, the arrhythmia, myocardial cells apoptosis, myocardial tissue glutathione peroxidase(GSH-Px), catalase(CAT), malondialdehyde(MDA), serum interleukin-6(IL-6), prostaglandin E2(PGE2) levels, myocardial tissue apoptosis, and Wnt/β-catenin/PPARγ pathway-related protein expression of rats in each group were measured. As compared with the control group, the arrhythmia score, the number of ventricular premature beats, ventricular fibrillation duration, myocardial cell apoptosis rate, MDA levels in myocardial tissues, serum IL-6 and PGE2 levels, Bax in myocardial tissues, and Wnt1 and β-catenin protein expression levels increased significantly in the model group, whereas the GSH-Px and CAT levels, and Bcl-2 and PPARγ protein expression levels in myocardial tissues reduced significantly. As compared with the model group, the arrhythmia score, the number of ventricular premature beats, ventricular fibrillation duration, myocardial cell apoptosis rate, MDA leve in myocardial tissues, serum IL-6 and PGE2 levels, Bax in myocardial tissues, and Wnt1 and β-catenin protein expression levels reduced in the drug intervention groups, whereas the GSH-Px and CAT levels and Bcl-2 and PPARγ protein expression levels in myocardial tissues increased. The groups of total flavonoids of buckwheat flower and leaf were in a dose-dependent manner. There was no significant difference in the levels of each index in rats between the propranolol hydrochloride group and the high-dose group of total flavonoids of buckwheat flower and leaf. The total flavonoids of buckwheat flower and leaf inhibit the activation of Wnt/β-catenin pathway, up-regulate the expression of PPARγ, reduce oxidative stress and inflammatory damage in myocardial tissues of arrhythmic rats, reduce myocardial cell apoptosis, and improve the symptoms of arrhythmia in rats.

ABSTRACT

Most information used to evaluate diabetic statuses is collected at a special time-point, such as taking fasting plasma glucose test and providing a limited view of individual's health and disease risk. As a new parameter for continuously evaluating personal clinical statuses, the newly developed technique "continuous glucose monitoring" (CGM) can characterize glucose dynamics. By calculating the complexity of glucose time series index (CGI) with refined composite multi-scale entropy analysis of the CGM data, the study showed for the first time that the complexity of glucose time series in subjects decreased gradually from normal glucose tolerance to impaired glucose regulation and then to type 2 diabetes (P for trend < 0.01). Furthermore, CGI was significantly associated with various parameters such as insulin sensitivity/secretion (all P < 0.01), and multiple linear stepwise regression showed that the disposition index, which reflects β-cell function after adjusting for insulin sensitivity, was the only independent factor correlated with CGI (P < 0.01). Our findings indicate that the CGI derived from the CGM data may serve as a novel marker to evaluate glucose homeostasis.

ABSTRACT

OBJECTIVE@#To investigate the synergistic interaction between the deltoid muscle and the rotator cuff muscle group in patients with rotator cuff tears (RCT), as well as the impact of the critical shoulder angle (CSA) on deltoid muscle strength.@*METHODS@#A retrospective analysis was conducted on clinical data from 42 RCT patients who met the selection criteria and were treated between March 2022 and March 2023. There were 13 males and 29 females, with an age range of 42-77 years (mean, 60.5 years). Preoperative visual analogue scale (VAS) score was 6.0±1.6. CSA measurements were obtained from standard anteroposterior X-ray films before operation, and patients were divided into two groups based on CSA measurements: CSA>35° group (group A) and CSA≤35° group (group B). Handheld dynamometry was used to measure the muscle strength of various muscle group in the shoulder (including the supraspinatus, infraspinatus, subscapularis, and anterior, middle, and posterior bundles of the deltoid). The muscle strength of the unaffected side was compared to the affected side, and muscle imbalance indices were calculated. Muscle imbalance indices between male and female patients, dominant and non-dominant sides, and groups A and B were compared. Pearson correlation analysis was used to examine the relationship between muscle imbalance indices and CSA as well as VAS scores.@*RESULTS@#Muscle strength in all muscle groups on the affected side was significantly lower than on the unaffected side ( P<0.05). The muscle imbalance indices for the supraspinatus, subscapularis, infraspinatus, and anterior, middle, and posterior bundles of the deltoid were 14.8%±24.4%, 5.9%±9.7%, 7.2% (0, 9.1%), 17.2% (5.9%, 26.9%), 8.3%±21.3%, and 10.2% (2.8%, 15.4%), respectively. The muscle imbalance indices of the anterior bundle of the deltoid, supraspinatus, and infraspinatus were significantly lower in male patients compared to female patients ( P<0.05); however, there was no significant difference in muscle imbalance indices among other muscle groups between male and female patients or between the dominant and non-dominant sides ( P>0.05). There was a positive correlation between the muscle imbalance indices of infraspinatus and VAS score ( P<0.05), and a positive correlation between CSA and the muscle imbalance indices of middle bundle of deltoid ( P<0.05). There was no correlation between the muscle imbalance indices of other muscle groups and VAS score or CSA ( P>0.05). Preoperative CSA ranged from 17.6° to 39.4°, with a mean of 31.1°. There were 9 cases in group A and 33 cases in group B. The muscle imbalance indices of the anterior bundle of the deltoid was significantly lower in group A compared to group B ( P<0.05), while there was no significant difference in muscle imbalance indices among other muscle groups between group A and group B ( P>0.05).@*CONCLUSION@#Patients with RCT have a phenomenon of deltoid muscle strength reduction, which is more pronounced in the population with a larger CSA.

ABSTRACT

Objective: To analyze the burden of disease attributable to high temperature exposure in China and globally from 1990 to 2019, and to study the current burden of disease in relevant populations. Methods: In October 2021, based on data from the global burden of disease 2019 (GBD 2019) study, population attributable fraction (PAF), number of deaths, mortality, disability-adjusted life year (DALY) and DALY rate of Chinese and global populations with different ages and genders in 1990 and 2019 were extracted and analyzed. The rate of change was calculated, the mortality rate was normalized by the age structure of the world standard population, and the causes of disease burden caused by high temperature exposure of Chinese residents were analyzed. Results: In 2019, compared with 1990, the PAF of Chinese and global population decreased by 43.98% and 12.41% respectively, the number of deaths increased by 29.55% and 49.40% respectively, the crude mortality rate increased by 7.81% and 3.30% respectively, the DALY decreased by 48.12% and 14.41% respectively, and the DALY rate decreased by 56.82% and 40.82% respectively. The mortality rate of the ≥70 age group was higher than that of other groups. The disease burden indicators such as PAF, standardized mortality and DALY attributable to high temperature exposure in men were higher than those in women. In 2019, the main cause of DALY affected by high temperature exposure in Chinese population was ischemic heart disease (84400 person-years), and the main cause of death was ischemic heart disease (4900 cases). Conclusion: The burden of diseases attributable to high temperature exposure is still serious in China and the world at large. Targeted interventions should be formulated for men, the elderly and people with occupational exposure, and a sound surveillance system should be established to reduce the burden of diseases caused by high temperature exposure.

ABSTRACT

Objective: To evaluate the efficacy of neoadjuvant chemotherapy (NACT) in the treatment of locally advanced olfactory neuroblastoma (ONB), and to explore the factors related to the efficacy of NACT. Methods: A total of 25 patients with ONB who underwent NACT in Beijing TongRen Hospital from April 2017 to July 2022 were retrospectively analyzed. There were 16 males and 9 females, with an average age of 44.9 years (ranged 26-72 years). There were 22 cases of Kadish stage C and 3 cases of stage D. After multiple disciplinary team(MDT) discussion, all patients were treated sequentially with NACT-surgery-radiotherapy. Among them, 17 cases were treated with taxol, cis-platinum and etoposide (TEP), 4 cases with taxol, nedaplatin and ifosfamide (TPI), 3 cases with TP, while 1 case with EP. SPSS 25.0 software was used for statistical analysis, and survival analyses were calculated based on the Kaplan-Meier method. Results: The overall response rate of NACT was 32% (8/25). Subsequently, 21 patients underwent extended endoscopic surgery and 4 patients underwent combined cranial-nasal approach. Three patients with stage D disease underwent cervical lymph node dissection. All patients received postoperative radiotherapy. The mean follow-up time was 44.2 months (ranged 6-67 months). The 5-year overall survival rate was 100.0%, and the 5-year disease-free survival rates was 94.4%. Before NACT, Ki-67 index was 60% (50%, 90%), while Ki-67 index was 20% (3%, 30%) after chemotherapy [M (Q1, Q3)]. The change of Ki-67 before and after NACT was statistically significant (Z=-24.24, P<0.05). The effects of age, gender, history of surgery, Hyams grade, Ki-67 index and chemotherapy regimen to NACT were analyzed. Ki-67 index≥25% and high Hyams grade were related to the efficacy of NACT (all P<0.05). Conclusions: NACT could reduce Ki-67 index in ONBs. High Ki-67 index and Hyams grade are clinical indicators sensitive to the efficacy of NACT. NACT-surgery-radiotherapy is effective for patients with locally advanced ONB.

ABSTRACT

Objective:To analyze the surgical types of patients with Kashin-Beck disease (KBD) in Shaanxi Province, and to provide reference for optimizing KBD surgery.Methods:Retrospective analysis was used to investigate KBD patients who underwent surgical treatment, and the patient's information was from the Shaanxi Provincial Endemic Disease Prevention and Control Information System. Patients with incomplete surgical treatment information were excluded, and χ 2 test was used to analyze the impact of factors such as gender, education level, living area, disease severity, and social environment on the selection of different surgical types (free body enucleation or joint replacement) for KBD patients. Using propensity score method to perform a 1 ∶ 1 match on patients with different surgical types, and analyzing the influencing factors of KBD patients receiving different types of surgical treatment through multivariate logistic regression. Results:From 2018 to 2020, a total of 1 084 KBD patients in Shaanxi Province underwent surgical treatment, including 555 males (51.20%) and 529 females (48.80%), with a median age of 64 years old. There were 917 patients (84.59%) in the Guanzhong region (Tongchuan, Xi'an, Weinan, Xianyang, Baoji), 120 patients (11.07%) in the northern Shaanxi region (Yulin, Yan'an), and 47 patients (4.34%) in the southern Shaanxi region (Ankang, Hanzhong, Shangluo). The number of patients with KBD grade Ⅰ,Ⅱ, and Ⅲ was 401 (36.99%), 525 (48.43%), and 158 (14.58%), respectively. Five hundred and forty-eight patients (50.55%) underwent free body enucleation surgery, and 536 patients (49.45%) underwent joint replacement surgery. Univariate analysis showed that different genders, educational levels, living areas, disease severity, economic status, whether to relocate, type of drinking water, type of staple food, and source of staple food were the influencing factors for KBD patients to choose the type of surgery (χ 2 = 81.82, 22.38, 93.68, 22.38, 5.17, 15.68, 13.82, 39.37, 49.63, P < 0.05). Among 374 pairs of patients who underwent free body enucleation and joint replacement through propensity score matching, multivariate logistic regression analysis found that high school and above education level [odds ratio( OR) = 0.42, P = 0.008], Guanzhong region ( OR = 0.12, P < 0.001), relocation ( OR = 0.60, P = 0.004), and drinking well water ( OR = 2.15, P = 0.001) were the influencing factors for KBD patients to choose different surgical types for treatment. Conclusion:When performing surgical treatment for KBD patients in Shaanxi Province, clinicians can consider the severity of the disease, as well as factors such as the education level, living area, relocation status, and type of drinking water of KBD patients, to provide more suitable surgical types for KBD patients.

ABSTRACT

Objective:To explore the predictive value of HACOR score [heart rate (H), acidosis (A), consciousness (C), oxygenation (O), and respiratory rate (R)] on the clinical outcome of non-invasive positive pressure ventilation in patients with pulmonary encephalopathy due to chronic obstructive pulmonary disease (COPD).Methods:A prospective study was conducted. The patients with COPD combined with pulmonary encephalopathy who were admitted to Henan Provincial People's Hospital from January 1, 2017 to June 1, 2021 and initially received non-invasive positive pressure ventilation were enrolled. Besides non-invasive positive pressure ventilation, standard medical treatments were delivered to these patients according to guidelines. The need for endotracheal intubation was judged as failure of non-invasive ventilation treatment. Early failure was defined as the need for endotracheal intubation within 48 hours of treatment, and late failure was defined as the need for endotracheal intubation 48 hours and later. The HACOR score at different time points after non-invasive ventilation, the length of intensive care unit (ICU) stay, the total length of hospital stay, and the clinical outcome were recorded. The above indexes of patients with non-invasive ventilation were compared between successful and failed groups. The receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive effect of HACOR score on the failure of non-invasive positive pressure ventilation in the treatment of COPD with pulmonary encephalopathy.Results:A total of 630 patients were evaluated, and 51 patients were enrolled, including 42 males (82.35%) and 9 females (17.65%), with a median age of 70.0 (62.0, 78.0) years old. Among the 51 patients, 36 patients (70.59%) were successfully treated with non-invasive ventilation and discharged from the hospital eventually, and 15 patients (29.41%) failed and switched to invasive ventilation, of which 10 patients (19.61%) were defined early failure, 5 patients (9.80%) were late failure. The length of ICU and the total length of hospital stay of the non-invasive ventilation successful group were significantly longer than those of the non-invasive ventilation failure group [length of ICU stay (days): 13.0 (10.0, 16.0) vs. 5.0 (3.0, 8.0), total length of hospital stay (days): 23.0 (12.0, 28.0) vs. 12.0 (9.0, 15.0), both P < 0.01]. The HACOR score of patients at 1-2 hours in the non-invasive ventilation failure group was significantly higher than that in the successful group [10.47 (6.00, 16.00) vs. 6.00 (3.25, 8.00), P < 0.05]. However, there was no significant difference in HACOR score before non-invasive ventilation and at 3-6 hours between the two groups. The ROC curve showed that the area under the ROC curve (AUC) of 1-2 hour HACOR score after non-invasive ventilation for predicting non-invasive ventilation failure in COPD patients with pulmonary encephalopathy was 0.686, and the 95% confidence interval (95% CI) was 0.504-0.868. When the best cut-off value was 10.50, the sensitivity was 60.03%, the specificity was 86.10%, positive predictive value was 91.23%, and negative predictive value was 47.21%. Conclusions:Non-invasive positive pressure ventilation could prevent 70.59% of COPD patients with pulmonary encephalopathy from intubation. HACOR score was valuable to predict non-invasive positive pressure ventilation failure in pulmonary encephalopathy patients due to COPD.

ABSTRACT

Objective:To screen the key exosomal long non-coding RNAs (lncRNAs) molecules that cause nasopharyngeal carcinoma cells to develop chemoradiotherapy resistance.Methods:In vitro, a model of concurrent chemoradiotherapy for human nasopharyngeal carcinoma cells was constructed, and the continuous shock method of high-dose concurrent chemoradiotherapy was used to induce the establishment of chemoradiotherapy-resistant nasopharyngeal carcinoma cell lines, and its resistance formation was verified. Exosomes produced by chemoradiotherapy-resistant cell lines and respective mother cell lines for nasopharyngeal carcinoma were extracted and identified. Finally, biochip technology was used to detect the differential expression levels of exosomal lncRNAs. Results:After 10 repeated treatments of concurrent chemoradiotherapy, CNE-1 CRR and CNE-2 CRR were successfully obtained. Compared with the mother cell lines, CNE-1 CRR and CNE-2 CRR had a tendency to transform from epithelial to interstitial morphology, and the number of cell clones was higher, and the values of average lethal dose (D 0), quasi-threshould dose (D q), survival fraction after 2 Gy irradiation (SF 2) and cell survival rate were higher. Nasopharyngeal carcinoma cells were detected by PCR chip of exosomal lncRNAs. Compared with their respective mother cell lines, 18 lncRNAs in CNE-1 CRR exosomes were significantly up-regulated and 31 lncRNAs were significantly down-regulated, and 15 lncRNAs were significantly up-regulated and 38 lncRNAs were significantly down-regulated in CNE-2 CRR exosomes. CNE-1 CRR also had similar expression profiles to CNE-2 CRR. Conclusion:There are significantly up-regulated and down-regulated lncRNAs in the exosomes of CNE-1 CRR and CNE-2 CRR.

ABSTRACT

Upper urinary tract calculi combined with dual infections is rare, and the antimicrobial therapy is complicated. This retrospective study analyzed the clinical data of 3 patients with upper urinary tract calculi combined with dual infection who were admitted to our hospital. Three patients were treated with piperacillin sulbactam combined with fluconazole for 1 week, according to the preoperative urine culture and drug sensitivity results. Endoscopic surgery was performed after the efficacy was determined by routine urine examination. After surgery, fluconazole was administered until the removal of the double-J tube for 2 weeks, and fluconazole was discontinued when no white blood cells or fungus were found. No recurrence of stones or infection was observed at a follow-up of 11 months to 2 years. The rational choice of antimicrobial drugs to treat upper urinary tract calculi combined with dual infection could create good conditions for endoscopic surgical intervention, thus achieving satisfactory clinical outcomes.

ABSTRACT

Objective: To investigate the clinicopathological characteristics of primary pulmonary NUT carcinoma. Methods: A total of 7 cases of primary pulmonary NUT carcinoma were collected from Fujian Provincial Hospital (n=5), Fuzhou Taijiang Hospital (n=1) and Binzhou City People's Hospital of Shandong Province (n=1) from January 2021 to April 2023. The clinical, histopathological, and immunohistochemical features were analyzed, and NUT rearrangement were detected by fluorescence in situ hybridization (FISH) with break-apart probes. Results: Seven cases were all male with age ranging from 32 to 73 years. The main clinical manifestations were cough, expectoration and chest tightness. Microscopically, NUT carcinoma was composed of monotonous proliferation of primitive-appearing small-to-medium round cells, with few eosinophilic cytoplasm, arranged in solid sheets, nests or clusters. Abrupt keratinization was typically observed in 4 cases (4/7), with high mitotic activities and necrosis. Immunohistochemistry (IHC) showed that the tumors were positive for NUT (7/7), CK7 (4/4), CK5/6 (5/6), p40 (6/7). Ki-67 index were 30%-80%. NUT gene segregation (7/7) was detected by FISH break probes. Conclusions: Primary pulmonary NUT carcinoma is rare and highly malignant. Diagnosis depends on histopathology and IHC, with molecular detection as an adjunct for diagnosis. Pathologists should be aware of the clinicopathological characteristics to avoid misdiagnosis.
