Effects of Acupuncture Combined with Biofeedback Therapy on Limb Motor Rehabilitation in Patients with Acute Stroke: Systematic Review and Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2022; 2022:9582077. [PMID: 35845965 PMCID: PMC9277156 DOI: 10.1155/2022/9582077] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 05/26/2022] [Accepted: 06/08/2022] [Indexed: 11/29/2022]
Abstract
Objective The purpose of the systematic review is to verify the effect of biofeedback therapy on limb motor rehabilitation in patients with acute stroke and to provide evidence-based medicine for the promotion and use of biofeedback therapy. Methods The randomized controlled trials (RCT) of biofeedback therapy in the treatment of cerebral palsy were searched in PubMed, EMBASE, ScienceDirect, Cochrane Library, China National Knowledge Infrastructure (CNKI), China VIP Database, Wanfang Database, and Chinese Biomedical Literature Database (CBM). The starting time and ending time of this study are from the time of building the database of the number of pieces to October 31, 2018. The data included in this study were extracted by two independent researchers and evaluated the bias risk of all the literature included in the study according to the Cochrane manual 5.1.0 criteria. RevMan5.4 statistical software was used to analyze the collected data by meta. Results This systematic review included 9 RCT studies with a total of 1410 patients. The results of meta-analysis showed that there were significant differences in the improvement of lower limb muscle tension, comprehensive spasm scale score, EMG score, and passive range of motion of ankle joint between biofeedback therapy and routine rehabilitation therapy. Conclusion Biofeedback therapy can improve lower limb muscle tension, spasticity, EMG integral value, and passive range of motion of ankle joint in children with cerebral palsy and provide better conditions for improving the motor ability of lower extremities in children with cerebral palsy. However, more studies and follow-up with higher methodological quality and longer intervention time are needed to further verify.

Abstract
AIM To develop and validate a radiomics nomogram for prediction of degree of differentiation in lung adenocarcinoma presenting as sub-solid or solid nodules. MATERIALS AND METHODS A total of 438 patients with histopathologically confirmed adenocarcinoma (248 non-poorly differentiated and 190 poorly differentiated) were divided into training cohort (n=235) and internal validation cohort (n=203) according to surgery sequence. Sixty patients form public TCIA dataset were selected for external validation. One thousand, two hundred and eighteen radiomics features were extracted from each volumetric region of interest and a least absolute shrinkage and selection operator logistic regression was applied to select meaningful radiomic features for building a radiomics score (Rad-score) model. A nomogram model incorporating the Rad-score and type was established after multivariable logistic regression. The discrimination efficiency, calibration efficacy, and clinical utility value of the nomogram were evaluated. RESULTS The Rad-score model could predict the differentiation degree of lung adenocarcinoma with an area under the curve (AUC) of 0.83 (95% confidence interval [CI]: 0.78-0.89) in the internal validation cohort. The AUC of the nomogram and radiographic model was 0.86 (95% CI: 0.80-0.91), 0.78 (95% CI: 0.72-0.84) in the internal validation cohort respectively. The AUC of the nomogram in the external validation cohort was 0.73 (95% CI: 0.58-0.88). Delong's test showed that the nomogram performed better than radiographic features alone (p=0.001). CONCLUSIONS The proposed radiomics nomogram has the potential to predict the differentiation degree of lung adenocarcinoma preoperatively.

Abstract
AIM Dental anxiety (DA) is a common problem worldwide because it renders dental treatment in children challenging. This study aimed to evaluate the long-term effect of dental treatment under general anaesthesia (GA) or physical restraints (PR) on children's DA and behaviour. METHODS A total of 103 children were recruited and divided into four groups: the GA group, PR group, cooperative (CO) group, and no experience (NE) group. The face version of the Modified Child Dental Anxiety Scale and modified Venham's Clinical Anxiety and Cooperative Behaviour Rating Scale were used to evaluate the level of DA and behaviour. CONCLUSION Dental treatment under GA is associated with a higher risk for DA when compared with that under PR in the long term. Increased DA may lead to uncooperative dental behaviour, although the agreement is only moderate.

Abstract
Abstract
Background
Corticosteroids systemically reduce immune system activity thereby limiting inflammation in the GI tract. Corticosteroid use is limited by deleterious systemic effects including immunosuppression and adverse effects on growth and development (Giles et al., 2018). The metabolism of dietary polysaccharides, such as plant cell wall xyloglucan, by gut symbionts has been demonstrated to be mediated by niche members of the human gut microbiota (Larsbrink et al., 2014). By caging corticosteroids like dexamethasone (DEX) with xyloglucans to be released by microbiota at the site of disease, there is potential to increase efficacy and limit adverse effects.
Mice deficient in Src homology 2 domain-containing inositol polyphosphate 5’-phosphatase (SHIP-/-) develop spontaneous CD-like ileal inflammation (Ngoh et al., 2016). We have used SHIP-/- mice to compare the efficacy of DEX versus caged DEX to reduce intestinal inflammation.
Aims
Caged DEX will reduce CD-like ileal inflammation in SHIP-/- mice at a lower dose than uncaged DEX because it is released and acts at the site of inflammation.
To assess this hypothesis we propose 3 aims:
Measure decaging activity along the GI tract of SHIP-/- mice ex vivo
Determine the minimum effective dose of DEX required to reduce ileal inflammation in SHIP-/- mice
Determine if equimolar and lower concentrations of caged DEX can reduce ileal inflammation in SHIP-/- mice
Methods
Intestinal contents and feces were harvested from SHIP-/- mice. Decaging activity was measured ex vivo, using caged resorufin (a fluorescent reporter).
SHIP-/- mice were orally gavaged with dexamethasone (or vehicle), or the molar equivalent of caged dexamethasone from 6–8 weeks of age. At 8 weeks of age, gross and histopathology were assessed and IL-1β concentrations were measured in full-thickness tissue homogenates.
Results
SHIP-/- mice demonstrated decaging activity in the cecal, colon, and fecal contents assayed. DEX treatment (3 or 1 mg/kg) of SHIP-/- mice eliminated CD-like gross pathology and histopathology, and reduced IL-1β concentrations in full-thickness ileal tissue homogenates from SHIP-/- mice compared to untreated or vehicle-treated mice. DEX did not have any harmful effects on the intestines of SHIP+/+ mice. 1 or 0.3 mg/kg molar equivalent of caged DEX (3-fold lower concentrations) eliminated CD-like gross pathology in SHIP-/- mice compared to treatment with vehicle control. Additionally, the mean IL-1β concentration in tissue homogenates of mice treated with the molar equivalent of 1 mg/kg caged DEX was reduced
Conclusions
SHIP-/- mice express decaging activity are effectively treated by DEX, and caged DEX shows similar efficacy at reducing SHIP-/- ileal pathology at lower concentrations than uncaged DEX. In future experiments, we will examine caged DEX at a lower concentration, and in 2nd mouse model of intestinal inflammation.

Abstract
Objective: To investigate the effects of regional citrate anticoagulation in continuous veno-venous hemofiltration (CVVH) of severe burn patients. Methods: A retrospective non-randomized controlled study was conducted. From January 2017 to August 2020, sixty-eight severe burn patients who met the inclusion criteria were treated with CVVH in Affiliated Hospital of Nankai University. According to the different methods of blood anticoagulation in CVVH treatment, patients were divided into citrate group (n=40) and heparin group (n=28). In the citrate group, 32 males and 8 females were (40±18) years old with total burn area of (62±14)% total body surface area (TBSA); in the heparin group, 22 males and 6 females were (38±16) years old with total burn area of (57±20)%TBSA. Creatinine level, C-reactive protein (CRP) value, and urea nitrogen level in serum of patients were recorded at 0 (immediately), 48, and 96 h after CVVH treatment in 2 groups, urea clearance index was calculated based on urea nitrogen level at 0, 48, and 96 h after CVVH treatment in 2 groups, platelet count (PLT), prothrombin time (PT), and activated partial thromboplastin time (APTT) in total coagulation of patients were recorded. The frequency of forced hemofiltration termination caused by adverse reactions such as severe hypocalcemia, aggravated wound bleeding, and new bleeding on non-wound surface of patients was recorded within 96 h of CVVH treatment. The duration of daily CVVH use from the beginning to the end was recorded. Data were statistically analyzed with chi-square test, analysis of variance for repeated measurement, independent samples t test, and Bonferroni correction. Results: There were no significant differences in urea nitrogen level, creatinine level, and CRP value in serum of patients between 2 groups at 0 h after treatment (P>0.05). At 48 and 96 h after treatment, urea nitrogen level, creatinine level, and CRP value in serum of patients in citrate group were significantly lower than those in heparin group (t=3.366, -2.315, 2.942, -2.657, 2.011, -2.441, P<0.05), and urea clearance index of patients in citrate group was significantly higher than that in heparin group (t=1.017, 2.233, P<0.05). There were no statistically significant differences in PLT, PT, and APTT of patients between 2 groups at 0 h after treatment (P>0.05). At 48 and 96 h, PLT of patients in citrate group was significantly higher than that in heparin group (t=-3.417, -4.143, P<0.05 or P<0.01), PT of patients in citrate group was significantly shorter than that in heparin group (t=2.760, -3.655, P<0.01), APTT of patients in citrate group was significantly shorter than that in heparin group (t=3.719, 5.146, P<0.05 or P<0.01). Within 96 h of treatment, there was 1 case of hypocalcemia and 1 case of aggravated wound bleeding resulting in forced hemofiltration termination in citrate group, but there was no new bleeding on non-wound surface; in heparin group, there was no hypocalcemia, but 7 cases of aggravated wound bleeding and 2 cases of new bleeding on non-wound surface (both at the tracheotomy site) resulting in forced hemofiltration termination. The use time of blood purification filter of patients in citrate group was (11.7±4.8) h, obviously longer than (6.6±2.5) h in heparin group (t=3.310, P<0.01). Conclusions: The use of regional citrate anticoagulation in CVVH treatment of severe burn patients has the advantages including little effect on coagulation function and high safety, can effectively prolong the use time of filter and improve the therapeutic effect, but this conclusion still needs to be further verified in clinical application.

Abstract
Objective: To determinate the range of quantitative myocardial perfusion parameters (MBF, MBV) in subjects without coronary artery lesions by dynamic computed tomography myocardial perfusion imaging (CTP). Methods: Subjects with occasional chest tightness or family history of coronary artery disease coming to Fuwai Hospital underwent coronary computed tomography angiography (CCTA) were prospectively enrolled. A total of 34 subjects [mean age (50±7) years, range from 33 to 65 years; 15 male and 19 female] were enrolled. Coronary lesions were not confirmed in any subjects using CCTA and volunteered for stress and rest dynamic CTP examination. MBF and MBV values were calculated in each myocardial segment using a 17-segment model. The global ranges of MBF and MBV were analyzed, and the gender variability and regional variability were compared. Results: The mean global MBF and MBV at rest and under stress were (115.5±27.4) ml·100 g-1·min-1, (212.8±40.8) ml·100 g-1·min-1 and (17.6±4.0) ml/100 g, (25.8±4.6) ml/100 g, respectively. The absolute and resolute reserves of MBF and MBV [(102.8±41.5) ml·100 g-1·min-1, 107.7%±52.5%; (9.3±5.2) ml/100 g, 62.1%±47.4%] were highest in the right coronary artery territory, but without any significant differences. The stress MBF and absolute reserve of MBF in females were higher than those of males [(228.6±39.9) ml·100 g-1·min-1, (113.3±46.2) ml·100 g-1·min-1; (192.8±33.4) ml·100 g-1·min-1, (77.0±41.2) ml·100 g-1·min-1] (both P<0.05). The MBF resolute reserve, rest MBV, stress MBV and MBV absolute and resolute reserves were higher in females, but without significant differences (all P>0.05). Conclusion: The mean global MBF and MBV at rest and under stress were (115.5±27.4) ml·100 g-1·min-1, (212.8±40.8) ml·100 g-1·min-1 and (17.6±4.0) ml/100 g, (25.8±4.6) ml/100 g. The MBF under stress perfusion and MBF absolute reserve of females are higher than those of males.

Abstract
Abstract
Background
The clinical features and long-term outcomes of patients with pulmonary Takayasu's arteritis associated pulmonary hypertension (PTA-PH) have not been well studied.
Purpose
To assess the clinical characteristics and long-term survival outcome in patients with PTA-PH.
Methods
We conducted a multi-center cohort study using the clinical, functional, and hemodynamic data from the National Rare Diseases Registry System of China. Patients with Takayasu's arteritis and pulmonary artery involvement, who fulfilled the 1990 American College of Rheumatology and/or modified Ishikawa criteria, from 13 referral centers of China, were included. The diagnosis of pulmonary hypertension (PH) was confirmed by right heart catheterization findings. The primary outcome was time from diagnosis of PTA-PH to the occurrence of all-cause death.
Results
Between Jan. 2007 and Jan. 2019, a total of 140 patients with PTA-PH were included, with a mean age of 41.4±14.3 years at diagnosis, and a female predominance (81%). The most common symptoms were exertional dyspnea (91%) and hemoptysis (36%). The majority of patients (87%) exhibited bilateral pulmonary artery involvement. Pulmonary lobar artery was the most frequently affected vessel (100%), followed by segmental artery (82%) and left/right pulmonary artery trunk (49%). Severely compromised hemodynamic profiles were identified in these patients, indicating by elevated mean pulmonary artery pressure (48, interquartile range [IQR] 38–59 mm Hg) and pulmonary vascular resistance (9.4, IQR 5.7–13.3 Wood U). The overall 1-year, 3-year, and 5-year survival rates in PTA-PH were 94.0%, 83.2%, and 77.2%, respectively (Figure). Predictors associated with increased risk of all-cause death were the presence of syncope (hazard ratio [HR]: 4.88; 95% CI: 1.62–14.74; p=0.005), N-terminal pro-B type natriuretic peptide level (HR: 1.04; 95% CI: 1.02–1.06; p<0.001), and right atrial pressure (HR: 1.07; 95% CI: 1.02–1.73; p=0.009).
Conclusions
In this national registry study, the reported clinical features and long-term prognosis of patients with PTA-PH are novel findings. These findings may provide new insights on this specific pulmonary hypertension entity.

Abstract
BACKGROUND Nasopharyngeal carcinoma (NPC) is a malignant head and neck tumor arising in the nasopharynx. MicroRNAs (miRNAs) are elucidated to exert tumor-suppressing function in human cancers. Numerous studies have manifested that miR-30a-5p serves as an anti-oncogene in various cancers. OBJECTIVE To research the biological function and molecular mechanism of miR-30a-5p in NPC. METHODS The morphology of NPC tissues was revealed by H&E staining. Transwell and wound healing assays were applied to investigate the effects of miR-30a-5p on NPC cell migration. The binding interaction between miR-30a-5p and nucleobindin 2 (NUCB2) was identified by luciferase reporter assay. Xenograft nude mice were used to detect the influence of miR-30a-5p on NPC tumor growth. RESULTS MiR-30a-5p was downregulated in NPC tissues and cells. The overexpression ofmiR-30a-5p inhibited proliferation, migration and invasion abilities of NPC cells. Moreover, NUCB2 was revealed to be a downstream target gene of miR-30a-5p, and knockdown of NUCB2 repressed the malignant behaviors of NPC cells and tumor growth. Additionally, rescue experiments revealed that miR-30a-5p suppressed the proliferation, migration and invasion of NPC cells via targeting NUCB2 in vitro. Meanwhile, in vivo assays depicted that NUCB2 overexpression rescued the effects induced by miR-30a-5p upregulation on tumor growth. CONCLUSION MiR-30a-5p modulates NPC progression by targeting NUCB2. These findings lay a foundation for exploring the clinical treatment of NPC.

Abstract
The nervous system exerts finely tuned control over all aspects of the life of an organism, including pain, sensation, growth, and development. Recent developments in tissue regeneration research have increasingly turned to small molecule peptides to tailor and augment the biological response following tissue loss or injury. In the present study, we have introduced the small molecule peptide galanin (GAL) as a novel scaffold-coating agent for the healing and regeneration of craniofacial tissues. Using immunohistochemistry, we detected GAL and GAL receptors in healthy periodontal tissues and in the proximity of blood vessels, while exposure to our periodontal disease regimen resulted in a downregulation of GAL. In a 3-dimensional bioreactor culture, GAL coating of collagen scaffolds promoted cell proliferation and matrix synthesis. Following subcutaneous implantation, GAL-coated scaffolds were associated with mineralized bone-like tissue deposits, which reacted positively for alizarin red and von Kossa, and demonstrated increased expression and protein levels of RUNX2, OCN, OSX, and iBSP. In contrast, the GAL receptor antagonist galantide blocked the effect of GAL on Runx2 expression and inhibited mineralization in our subcutaneous implantation model. Moreover, GAL coating promoted periodontal regeneration and a rescue of the periodontal defect generated in our periodontitis model mice. Together, these data demonstrate the efficacy of the neuropeptide GAL as a coating material for tissue regeneration. They are also suggestive of a novel role for neurogenic signaling pathways in craniofacial and periodontal regeneration.

Abstract
Emerging energy harvesting yarns, via triboelectric effects, have wide application prospects in new-generation wearable electronics. However, few studies have been carried out regarding simultaneously achieving high electrical performance, mechanical robustness, and comfortability in industrial-scalable yarn. Here, an electronic yarn twisted into Fermat spiral, which has outstanding dynamic structure stability, is reported. The Fermat-spiral-based energy yarns (FSBEY) can simultaneously realize ultrahigh abrasion resistance (over 5000 Martindale standard abrasion cycles), stable reversible strain (100%), and excellent electrical output. Considerably high output (105 V, ≈1.2 µA under 2 Hz) can be attained upon contacting a single yarn (30 cm) with latex material, which is superior to most state-of-the-art stretchable triboelectric yarns. The application of these FSBEY in wireless gesture recognition, smart screen information protection, and harvesting of energy from water dropletsis demonstrated. Moreover, textiles knitted from the FSBEY have distinguished waterproof nature and are breathable. This work shows a feasible proposal for building future "energy garments".

Abstract
Objective: To observe the efficacy of macular buckling in the treatment of highly myopic traction maculopathy. Methods: Retrospective case series study. The patients with high myopia who underwent macular buckling at the Zhongshan Ophthalmic Center of Sun Yat-sen University from June 2014 to June 2019 were enrolled, including 136 males and 212 females. The age was (56.68±11.59) years old. The outcomes measured included retinal reattachment rate, foveoschisis recovery rate, macular hole closure rate, postoperative best corrected visual acuity (BCVA), axial length (AL), and complications. The measurements were recorded preoperatively and at 1 month, 6 months, 1 year, 2 years, and 3 years postoperatively. The data was statistically analyzed using paired t test. Results: A total of 378 eyes were included, including 216 eyes with foveoschisis and macular detachment and 162 eyes with macular holes and macular detachment. Among them, 296 eyes underwent macular buckling, and the other 82 eyes underwent macular buckling combined with pars plana vitrectomy. During the follow-up period, 373 eyes (98.68%) achieved retinal reattachment; in patients with foveoschisis, 204 eyes (94.44%) were recovered; in patients with macular holes, 89 eyes (54.09%) achieved closure. All the postoperative results of BCVA were better than the preoperative value (1.459±0.841). BCVA continued to increase from postoperative month 1, remained stable at 1 year, and reached 0.908±0.606 at 3 years (t=6.896, P<0.01). All the postoperative results of AL were shorter than the preoperative value. The AL shortened by (4.423±1.740)mm at one month (t=33.144, P<0.01), increased gradually thereafter, remained stable at 1 year, and shortened by (2.101±1.643) mm at three years (t=6.392, P<0.01). The common complications included transient high intraocular pressure in 98 eyes (25.92%), epiretinal hemorrhage in 67 eyes (17.72%), and vitreous hemorrhage in 9 eyes (2.38%), which all resolved spontaneously within 1 month. In the early postoperative period, all patients had a certain degree of eye movement limitation, and 39 eyes (10.31%) had diplopia which resolved within 6 months without treatment. The strabismus surgery was arranged to treat esotropia in 6 eyes (1.58%). The macular buckle was removed from 1 eye (0.26%) because of the inability to tolerate diplopia. There were 8 eyes (2.11%) requiring a second operation to adjust the position of the buckle. The macular buckle was also removed from 4 eyes (1.05%) due to the implant rejection. Conclusion: Macular buckling can effectively shorten the AL, resolve posterior scleral staphyloma, and improve vision in the treatment of highly myopic traction maculopathy.

Abstract
A reliable and efficient method for the simultaneous extraction and determination of antibiotics of ciprofloxacin and levofloxacin from milk was developed with solid phase extraction based on tailored adsorbent materials of deep eutectic solvents modified phenolic resin (DES-R-SPE). Six types of polyhydric alcohol-based hydrophilic DESs were prepared to modify the phenolic resin with the compositions of 3-aminophenol as a functional monomer, glyoxylic acid as a crosslinker, and polyethylene glycol 6000 as a porogen. And the prepared DES-Rs showed better extraction capacities for the target analytes than the unmodified phenolic resin because of more hydrogen bonding and electrostatic interactions supplied by DESs. The choline chloride-glycerol-based resin (DES1-R) with the highest adsorption amounts was selected and the adsorption behavior of it was studied with static adsorption and the dynamic adsorption performance; the adsorption process followed Freundlich isotherm (R2 ≥ 0.9337) and pseudo-second-order (R2 ≥ 0.9951). The present DES1-R-SPE method showed good linear range from 0.5 to100 μg mL-1 (R2 ≥ 0.9998), good recoveries of spiked milk samples (LEV, 96.7%; CIP, 101.5%), and satisfied repeatability for intra-day and inter-day (LEV, RSD≤5.4%; CIP, RSD≤4.6%).

Abstract
Objective: To explore the experience of intimate partner-related violence (IPV) and its correlation with high-risk sexual behaviors among MSM. Methods: MSM were recruited in Ji'nan, Qingdao, and Jining of Shandong province from April to July 2019. Information on socio-demographic characteristics, AIDS prevention and control knowledge, IPV experience in the last year and high-risk sexual behaviors in the previous six months was collected by face-to-face questionnaire. EpiData 3.1 and SPSS 24.0 software were used for data cleansing and statistical analysis. Results: The average age of the 1 122 MSM was (29.80±8.78) years, with 68.1% (764/1 122) unmarried. 9.8% (110/1 122) had IPV experiences in the past year. MSM who came from Jining and Qingdao, living in the local area for more than two years, met their sexual partners in bar/bathroom/park, having no basic knowledge about AIDS, being drug users, and diagnosed with STD in the previous year, had a higher proportion of IPV experiences in the last year (P<0.05). 49.0% (550/1 122) and 20.9% (234/1 122) had unprotected anal intercourse and group sex behavior during the past six months, respectively. The results of multivariate logistic regression showed that MSM who experienced IPV were likely to have unprotected anal intercourse and group sex behavior during the past six months (aOR = 1.82, 95%CI: 1.14-2.91;aOR = 3.30, 95%CI: 2.10-5.20) than those did not experience IPV. Conclusions: IPV exists in the MSM population, and the IPV experience is positively associated with high-risk sexual behaviors. Targeted intervention to reduce the risk of high-risk sexual behaviors should be taken among MSM who experienced IPV.

Abstract
Background COVID-19 has spread worldwide and become a pandemic. We report the epidemiological and clinical characteristics of cluster infections. Methods Data of clustered cases were retrieved from the public health emergency monitoring information system of China. We analyzed the incubation period, generation gap, secondary attack rate, and viral load in various grouped cases. Results A total of 60 COVID-19 infection clusters including 226 patients and 19 asymptomatic cases involving four generations were analyzed. With the increase of transmission generations, secondary attack rate decreased (P<0.001) and severity alleviated (P = 0.008). The median incubation period and intergenerational interval were 9 and 6 days, respectively. The secondary attack rate was 7.1% in the index cases, 5.0% in the first generation, 1.0% in the second generation, and 4.7% overall. Severe cases were seen more in the index (13, 65%) and first generation (7, 35%) ones, who had a significantly higher viral load than the mild and moderate ones. Conclusions With the increase of transmission generation, secondary infection rate and severity decreased. Severe patients had a higher virus load. Patients in the incubation period and asymptomatic carriers were potential infection sources who might play an important role in transmission.

Abstract
Objective: To propose a method of cervical cytology screening based on deep convolutional neural network and compare it with the diagnosis of cytologists. Method: The deep segmentation network was used to extract 618 333 regions of interest (ROI) from 5, 516 cytological pathological images. Combined with the experience of physicians, the deep classification network with the ability to analyze ROI was trained. The classification results were used to construct features, and the decision model was used to complete the classification of cytopathological images. Results: The sensitivity and specificity were 89.72%, 58.48%, 33.95% and 95.94% respectively. Among the smears derived from four different preparation methods, this algorithm had the best effect on natural fallout with a sensitivity of 91.10%, specificity of 69.32%, positive predictive rate of 41.41%, and negative predictive rate of 97.03%. Conclusion: Deep convolutional neural network image recognition technology can be applied to cervical cytology screening.

Abstract
BACKGROUND Follicular cells give rise to thyroid cancer. Worldwide thyroid cancer incidence continues to rise in recent decades but the mortality rate remains at a stable level. The discovery of novel molecular mechanisms in the pathogenesis of thyroid cancer will promote new diagnostic or therapeutic strategies. Circular RNA (circRNA) is a type of noncoding RNA which is characterized by the covalently closed loop and non-protein coding capacity. The abnormal expression of circRNAs is an important part during the pathogenesis and development of thyroid cancer. CircTP53 is a novel circRNA, and we aimed to investigate its function in the pathogenesis of thyroid cancer and to further demonstrate the underlying molecular mechanism. METHODS The levels of circTP53, miR-1233-3p, and other relative mRNA were analyzed by qRT-PCR. Protein levels were shown by Western blot. RNA-pulldown assay and luciferase assay were employed to examine the interaction between circTP53 and miR-1233-3p. Cell proliferation was analyzed by the MTT assay. RESULTS CircTP53 was a circRNA highly expressed in thyroid cancer tissues. CircTP53 promoted cell proliferation and cell viability of TPC-1 cells. Knockdown of circTP53 inhibited the expression of Mouse double minute 2 (MDM2) and increased the protein level of p53. CircTP53 acted as a target of miR-1233-3p to increase MDM2 expression. p53 expression in thyroid cancer tissue exhibited a negative correlation with circTP53 expression. CONCLUSION In thyroid cancer, overexpressed circTP53 decreased the protein level of p53 via targeting miR-1233-3p/MDM2 axis and promoted cancer cell proliferation.

Abstract
Objective: To understand the relationship between new-type drug use and high risk behavior in men who have sex with men (MSM) in Shandong province. Methods: Cross-sectional surveys was conducted to collect the information about demographics, sexual and drug use behaviors of MSM and HIV-related services in MSM in three sentinel surveillance sites in Shandong from April to July in 2019. Blood samples were taken from the MSM for serological tests of HIV antibody and syphilis antibody. Results: A total of 1 203 MSM were included in this study. The average age of the MSM was 30.2±8.9 years. Among these MSM, 67.7% (815) were unmarried; 66.9% (805) had education level of college or above; 62.2% (721/1 160) had unprotected sex behaviors and 16.3% (189/1 160) had group sex behavior in the past six months and 54.2% (652/1 203) ever used new-type drugs. HIV infection and syphilis prevalence rates were 3.1% (37/1 203) and 4.7% (56/1 203), respectively. Multivariable logistic analysis indicated that MSM who had unprotected anal sex in the past six months were more likely to be from Qingdao (aOR=1.59, 95%CI:1.13-2.23), with education level of high school or below (aOR=1.61, 95%CI: 1.20-2.16), with male sex partners from bars/dance halls or other venues (aOR=1.69, 95%CI: 1.06-2.69), with HIV knowledge awareness score <6 (aOR=1.55, 95%CI: 1.01-2.37), with ≥2 sex partner in the past week (aOR=1.48, 95%CI: 1.12-1.95), to have group sex behaviors in the past six months (aOR=2.43, 95%CI:1.61-3.67) and to use new-type drugs (aOR=1.46, 95%CI: 1.11-1.91). MSM who had group sex were more likely to have following features: being from Qingdao (aOR=2.21, 95%CI: 1.45-3.38), non-Shandong residents (aOR=2.13, 95%CI: 1.28-3.55), HIV knowledge awareness score ≥6 (aOR=3.11, 95%CI: 1.55-6.25), ever having unprotected anal sex behaviors (aOR=2.60, 95%CI: 1.71-3.96) and ever having male commercial sex (aOR=3.38, 95%CI: 1.92-5.95) in the past six months, ever using new-type drugs (aOR=2.71, 95%CI: 1.82-4.04), and never having HIV testing in the past year (aOR=2.66, 95%CI: 1.59-4.43). Conclusion: New-type drug use is common in MSM in Shandong. The use of new-type drugs promotes unprotected sex and group sex in MSM. Surveillance and intervention measures targeting this population should be strengthened.
