Objective To investigate the frequency of therapy-oriented oral radiation in Nanping, China and its distribution, and to provide a basis for the rational application of therapy-oriented oral radiation and the effective allocation of resources in Nanping. Methods A questionnaire was designed to investigate the frequency of therapy-oriented oral radiation in all oral radiation diagnosis and treatment institutions in Nanping. Results In 2021, there were 54 oral radiation diagnosis and treatment institutions and 79 oral radiation machines in Nanping. The total frequency of therapy-oriented oral radiation was 61593 visits and the radiation frequency was 19.54 visits per thousand patients. The average annual frequency of medical institutions at all levels was 721.87 to 3713.25 visits per institution; the male-to-female composition ratio of frequency of therapy-oriented oral radiation in December 2021 was 50.5%:49.5%. The proportion of radiation frequency of different devices was as follows: 38.7% (intraoral dental film), 46.5% (oral panorama), 10.3% (oral computed tomography [CT]), and 4.5% (cranial photography). The proportion of radiation frequency in patients of different ages was as follows: 17.1% (0−15 years), 48.2% (15−40 years), and 34.7% (over 40 years). The frequency of therapy-oriented oral radiation grew by 77.43%, 35.18%, and 8.16% every two years from 2015 to 2021, respectively. Conclusion The frequency level of therapy-oriented oral radiation in Nanping is at the level of Class II health care. The distribution of therapy-oriented oral radiation is highly unbalanced and is related to the level of economic development. Private healthcare institutions are growing rapidly, and public healthcare institutions of grade two and above occupy the main healthcare resources. The oral panorama accounts for the most, cranial photography accounts for the least, and oral CT is the fastest-growing portion. Therapy-oriented oral radiation is predominantly performed in the young and middle-aged populations, regardless of sex. Except for intraoral dental films, the general trend is upward.

Objective To investigate the sleep status and emotional-behavioral problems among preschool children in Yanping District of Nanping City in Fujian Province, and analyze the correlation between sleep status and emotional-behavioral problems. Methods A total of 500 preschool children were selected as subjects of this study. The Children's Sleep Habits Questionnaire (CSHQ) and the Strengths and Difficulties Questionnaire (SDQ) were used to evaluate the sleep status and emotional-behavioral problems of the children. Additionally, general information about the children was collected. Comparisons were made between children with different demographic and sociological characteristics in terms of their sleep status and emotional-behavioral problems, and the correlations between sleep status and emotional-behavioral problems were analyzed. Results The detection rates of sleep disorders and emotional-behavioral problems among preschool children were 15.00% and 14.80% respectively. The detection rate of emotional-behavioral problems was significantly higher in boys than in girls (P < 0.05). No significant differences were found in the detection rates of sleep disorders and emotional-behavioral problems among children of different ages, birth weights, whether they were only children, birth methods, whether they were premature, maternal pregnancy ages, father's education level, sleep environments, or co-sleeping situations (P>0.05). Both the detection rates of sleep disorders and emotional-behavioral problems significantly decreased with the improvement of mother's education level and increased with the increase in daily screen exposure time (P < 0.05). Compared with children with normal/borderline scores on each dimension (conduct problems, peer problems, emotional symptoms, hyperactivity, prosocial behavior) and total scores of SDQ, children with abnormal scores on each dimension and total scores had significantly higher incidences of sleep disorders (P < 0.05). Multivariate analysis showed that sleep disorders were the risk factors for the scores of occurrence of conduct problems, peer problems, emotional symptoms, hyperactivity, prosocial behavior, and abnormal total difficulties scores among preschool children (P < 0.05). Conclusion The overall sleep status of preschool children in Yanping District of Nanping City is relatively good, but there are still many sleep problems. Sleep disorders can increase the risk of emotional-behavioral problems in children, and excessive screen exposure may increase the risk of sleep disorders and emotional-behavioral problems in children.

Background::Pulmonary arterial hypertension (PAH) is characterized by excessive proliferation of small pulmonary arterial vascular smooth muscle cells (PASMCs), endothelial dysfunction, and extracellular matrix remodeling. G protein-coupled receptor kinase 2 (GRK2) plays an important role in the maintenance of vascular tone and blood flow. However, the role of GRK2 in the pathogenesis of PAH is unknown.Methods::GRK2 levels were detected in lung tissues from healthy people and PAH patients. C57BL/6 mice, vascular smooth muscle cell-specific Grk2-knockout mice ( Grk2?SM22), and littermate controls ( Grk2flox/flox) were grouped into control and hypoxia mice ( n = 8). Pulmonary hypertension (PH) was induced by exposure to chronic hypoxia (10%) combined with injection of the SU5416 (cHx/SU). The expression levels of GRK2 and Yes-associated protein (YAP) in pulmonary arteries and PASMCs were detected by Western blotting and immunofluorescence staining. The mRNA expression levels of Grk2 and Yes-associated protein ( YAP) in PASMCs were quantified with real-time polymerase chain reaction (RT-PCR). Wound-healing assay, 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay, and 5-Ethynyl-2′-deoxyuridine (EdU) staining were performed to evaluate the proliferation and migration of PASMCs. Meanwhile, the interaction among proteins was detected by immunoprecipitation assays. Results::The expression levels of GRK2 were upregulated in the pulmonary arteries of patients with PAH and the lungs of PH mice. Moreover, cHx/SU-induced PH was attenuated in Grk2?SM22 mice compared with littermate controls. The amelioration of PH in Grk2?SM22 mice was accompanied by reduced pulmonary vascular remodeling. In vitro study further confirmed that GRK2 knock-down significantly altered hypoxia-induced PASMCs proliferation and migration, whereas this effect was severely intensified by overexpression of GRK2. We also identified that GRK2 promoted YAP expression and nuclear translocation in PASMCs, resulting in excessive PASMCs proliferation and migration. Furthermore, GRK2 is stabilized by inhibiting phosphorylating GRK2 on Tyr86 and subsequently activating ubiquitylation under hypoxic conditions. Conclusion::Our findings suggest that GRK2 plays a critical role in the pathogenesis of PAH, via regulating YAP expression and nuclear translocation. Therefore, GRK2 serves as a novel therapeutic target for PAH treatment.

Objective·To describe the level of multiple symptom distress and physical activity in children and adolescents with cancer,analyze symptom distress profiles,and explicit the relationship between latent profiles and physical activity.Methods·From November 2021 to March 2023,the convenient sample method was used to recruit children and adolescents with cancer aged 10-18 years old,who had been treated for more than 1 month in the Departments of Hematology/Oncology,Shanghai Children's Medical Center and Xin Hua Hospital,Shanghai Jiao Tong University School of Medicine.The questionnaires,including General Information Questionnaire,Memorial Symptom Assessment Scale 10-18(MSAS 10-18)and Modified Chinese Version of Children's Leisure Time Activities Study Survey(CLASS-C),were used.Latent profile analysis was used to identify whether the level of multiple symptom distress in children and adolescents with cancer was population heterogeneity and its explicit characteristics.Whether there were differences in physical activity levels among different profiles of symptom distress was also analyzed.Results· A total of 165 valid questionnaires were collected,with an effective response rate of 91.7％.The symptom distress scores of the top five occurrence rates of symptoms in children and adolescents with cancer were lack of energy with a median of 1(1,2)point,nausea 1(1,2)point,lack of appetite 2(2,3)points,sweat 1(1,2)point,and pain 1(1,2)point.The physical activity level of the patients was mainly light,with a median of 2 530.00(1 577.50,3 721.00)min/week,and moderate to vigorous physical activity was relatively lower[70.00(10.00,197.50)min/week].The patients with cancer could be divided into two latent profiles:"high fatigue-high nausea-high hair loss-high sleepy"and"high fatigue-low nausea-low vomiting-low sleepy",which were named as high symptom distress(n=47,30.6％)and low symptom distress(n=l 18,69.4％)separately.Multivariate Logistic regression analysis showed that patients with acute lymphoblastic leukemia were more likely to be classified as high symptom distress group,and outpatients in the latest hospital visit were more likely to classified as low symptom distress group(both P＜0.05).In addition,patients with high symptom distress had a higher level of light physical activity(P＜0.05),and had a lower level of moderate to vigorous physical activity,but the difference was not statistically significant.Conclusion·There is population heterogeneity in the multiple symptom distress in children and adolescents with cancer.Disease type(acute leukemia)and the way of the latest hospital visit(through outpatient department)are the predictors of symptoms profiles of patients with cancer.Patients who experience high symptom distress have higher level of light physical activity,and perhaps lower level of moderate to vigorous physical activity.

OBJECTIVE: To investigate the effects of down-regulating of c-Met expression to the proliferation, invasiveness and apoptosis of human multiple myeloma RPMI 8226 cells. METHODS: According to transfection the RPMI8226 cells were dividide into RPMI 8226 (untreated RPMI 8226), RPMI 8226 /shRNA-Met and RPMI8226/shRNA-control group, respectively. Protein expression level of c-Met was detected by Western blot so as to evaluate transfection condition; the proliferation of the cells was detected by MTT; apoptosis and cycle of the cells were detected by flow cytometry; effect of c-Met/shRNA on RPMI 8226 cell adhesion was detected by RPMI 8226 cell adherence to ECM (Fn and Matrigel) and ECV304 cells. Invasiveness of RPMI 8226 cell was detected by Transwell assay. RESULTS: The c-Met short hairpin RNA (shRNA) was successfully transfected into RPMI 8226 cells, and could inhibit the expression of c-Met significantly. The down-regulation of c-Met could inhibit the proliferation of RPMI 8226 cells significantly. The percentage of cells in the G/G phase and apoptotic rate (sub-G) in the RPMI 8226/shRNA-Met group were higher than those in the control group, the adhesion rate and the number of migrated RPMI 8226/shRNA-Met cells were decreased significantly as compared with control group. There were no significant differences in each indexes between RPMI 8226/shRNA-control and control group. CONCLUSION Knockdown of c-Met can affect the proliferation, adherence, invasiveness and apoptosis of human multiple myeloma RPMI 8226 cells.

Objective:To systematically review the clinical effectiveness of combined postoperative adjuvant transcatheter arterial chemoembolization (TACE) with portal vein chemotherapy (PVC) versus TACE alone in patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT).Methods:Databases including PubMed, Embase, Cochrane Library, Medline, Web of Science, CNKI, China Biology Medicine, Wan Fang and VIP were searched from Jan 1st 2000 to Jun 30th 2019 for eligible studies on clinical effectiveness of combined postoperative adjuvant TACE with PVC versus TACE alone in patients with HCC and PVTT. The primary endpoints were overall survival (OS) and disease-free survival (DFS). The secondary endpoint was adverse events. These endpoints were evaluated by odds ratio ( OR) and 95% confidence interval ( CI) using Review Manager 5.3 software. Results:Nine studies with 642 patients were enrolled in this meta-analysis. There were 323 patients in the TACE group and 319 patients in the TACE plus PVC group. The pooled OR for the 1-, 2-, and 3-year OS were all significantly better in the TACE plus PVC group than the TACE group (1-year OS, OR=2.20, 95% CI: 1.53-3.17; 2-year OS, OR=2.44, 95% CI: 1.69-3.53; 3-year OS, OR=2.30, 95% CI: 1.52-3.46) (all P<0.05). Similarly, significantly better results were observed in the pooled OR for the 1-, 2-, and 3-year DFS (1-year DFS, OR=2.56, 95% CI: 1.70-3.86; 2-year DFS, OR=2.27, 95% CI: 1.19-4.32; 3-year DFS, OR=3.03, 95% CI: 1.55-5.92) (all P<0.05). There were no significant differences in the incidences of adverse events between the two groups (all P>0.05). Conclusion:Postoperative adjuvant TACE combined with PVC for patients with HCC and PVTT was safe and effective, and was significantly better than TACE alone in long-term prognosis. Large-scale, multi-center, prospective studies are needed to support the conclusion.

Objective:To explore the experience and needs of symptom management care of parents of cancer children during chemotherapy so as to provide a reference for improving the level of symptom management.Methods:Between November 2018 and April 2019, phenomenological research method was used to conduct a semi-structured interview with 14 parents of cancer children in the stage of chemotherapy from two hospitals. Colaizzi seven step analysis was used to the data analysis.Results:The care experience of symptoms and adverse reactions of parents of children with cancer during chemotherapy was refined into two themes, namely the process of learning and growth, and the transformation of psychological adaptation. The main needs of care were information needs, communication needs and psychological support needs.Conclusions:Parents of children with cancer are learning and growing up in the process of treatment and symptom care, and there are many needs. Medical and nursing staff should work closely with the children and their parents to meet the parents' needs for knowledge, communication and psychological support for symptom care, improve the care experience of parents and alleviate the pain of children.

Objective To investigate the status of human intestinal parasitic diseases in Nanping City from 2014 to 2018, so as to provide reference for the development of the effective control measures. Methods Administrative villages were selected using the two-stage cluster sampling in Nanping City from 2014 to 2018, and surveillance of human intestinal parasitic diseases was performed in 5 administrative villages in each county (district) of Nanping City. Intestinal parasitic infections were detected using a modified Kato-Katz thick smear method (two smears for a single stool sample) in villagers, and the hookworm species was differentiated. In addition, the eggs of Enterobius vermicularis were detected using the adhesive tape method in children aged 3 to 6 years. Results A total of 6 317 villagers were detected in Nanping City from 2014 to 2018, and the overall prevalence of human intestinal parasitic infections was 2.15%. There was year- (χ² = 10.53, P < 0.05) and gender-specific prevalence of human intestinal parasitic infections in Nanping City during the study period (χ² = 17.00, P < 0.01). The prevalence of human intestinal parasitic infections increased with age, and there was age-specific prevalence of human intestinal parasitic infections in Nanping City (χ² = 102.62, P < 0.01). A total of 945 children at ages of 3 to 6 years were detected, and the prevalence of E. vermicularis infection was 3.28%. Conclusions The prevalence of human intestinal parasitic infections is at a low level in Nanping City from 2014 to 2018, and the infection mainly occurs in villagers of advanced age and low education levels. Further comprehensive measures are required to control intestinal parasitic infections in key populations.

OBJECTIVETo explore the effects of the combined therapy of heat sensitive moxibustion and acupoint injection on endometrial receptivity of hypdrosalphinx infertility in the patients after hysteroscopy and laparoscopy on the base of routine post-operative anti-inflammation.

METHODSA total of 210 patients of hypdrosalphinx infertility after hysteroscopy and laparoscopy were divided into a combined therapy group, a heat sensitive moxibustion group and a control group, 70 cases in each one according to the random number table. In the control group, the intravenous drip of cefoxitin sodium was adopted, and the anti-inflammation treatment was given for 1 week after operation. In the heat sensitive moxibustion group, on the basis of the treatment as the control group, the heat sensitive moxibustion was applied after vaginal bleeding stopped. The acupoints were Yaoyangguan (GV 3), Guanyuan (CV 4), Qihai (CV 6), Shenshu (BL 23), Sanyinjiao (SP 6), Yinlingquan (SP 9) and Zigong (EX-CA1). The acupoints were modified according to the different syndromes. In the combined therapy group, on the basis of the regimen as the heat sensitive moxibustion group, after vaginal bleeding stopped, the acupoint injection was given alternatively at bilateral Tiangong (extra, 1.0 cm inferior and bilateral to the cervix) with lidocaine 1 mL, amikacin 2 mL and salvia injection 2 mL. The treatment was given once every day, the treatment for 10 times as one course and a total of 3 courses were required. The endometrial type, thickness, uterine arterial plusatility index (PI) and resistance index (RI) were observed in the patients of each group.

RESULTSAfter treatment, the numbers of A-type endometrial type in the combined therapy group and the heat sensitive moxibustion group were remarkably higher than those of the control group [57.1% (40/7) vs 31.4% (22/70), 50.0% (35/70) vs 31.4% (22/70), both<0.05]. The endometrial thickness after treatment was all increased as compared with that before treatment in each group (all<0.05). The increasing degree in the combined therapy group was better than either the heat sensitive moxibustion group or the control group (both<0.05). The improvement in the heat sensitive moxibustion group was superior to the control group (<0.05). PI and RI in the combination group and PI in the control group were decreased after treatment (all<0.05). The improvements of PI and RI in the combination group were better than those in the heat moxibustion group (both<0.05), which were superior to those in the control group (all<0.05).

CONCLUSIONIn the patients of hypdrosalphinx infertility after hysteroscopy and laparoscopy, the combined therapy of heat sensitive moxibustion and acupoint injection increases endometrial thickness, reduces uterine arterial resistance and improves endometrial receptivity.

Objective To determine the impact and the risk factors of different methods of preoperative biliary drainage (PBD) for malignant obstruction jaundice (MOJ) on overall survival (OS).Methods Databases including the PubMed,Medline,Web of Knowledge,and other databases were searched up to 30th April,2018 for clinical studies which compared the OS rates between percutaneous transhepatic biliary drainage (PTBD) and endoscopic biliary drainage (EBD) for MOJ.Hazard ratio (HR) and Odds Ratio (OR) with 95％ confidence interval (CI) were performed using the Review Manager 5.3 software to synthesize the results.Results Nine studies were enrolled in this meta-analysis,which included 818 patients in the PTBD group and 1253 patients in the EBD group.EBD was shown to be superior to PTBD in OS (HR=0.63,95％ CI:0.51～0.77,P＜0.05).Risk factors analysis showed that patients in the EBD group had a higher rate of early tumor stage (P＜0.05) and a lower rate of lymphatic metastasis (P＜0.05).When compared with the PTBD group,the EBD group had a lower rate of intraoperative bleeding (P＜0.05),and a higher rate of adjuvant therapy (P＜0.05).Conclusion In PBD for patients with resectable MOJ,there was insufficient evidence to support EBD to be superior to PTBD in OS.
