Objective To study the nutritional risks in elderly patients with prostate cancer and explore its related factors.Methods 346 elderly patients with prostate cancer in Wuhan area from May 2013 to May 2014 were chosen as the objects in this study.Nutritional risk screening 2002 was used to evaluate nutritional risk.The sleep quality,anxiety,lower urinary tract symptoms,differentiation and other data of patients were collected.The influencing factors for nutritional risk in the patients were analyzed.Results The ratio of nutritional risk in elderly advanced prostate cancer patients was 35.3％ (122/346).The nutritional risk was increased with age (P＜0.05).The prostate cancer patients with nutritional risk had a higher international prostate symptom score (IPSS) (P＜ 0.05).Monovariate factor analysis showed that sleep quality,operation,pathology staging,radiotherapy,chemotherapy,lower urinary tract symptoms (LUTS) were the impact factors for nutritional status in elderly patients with prostate cancer (P＜0.05).Logistic regression analysis showed that age (OR=0.29),sleep quality (OR=0.25) were the protective factors for the nutritional status,while surgery (OR=12.67),pathological staging (OR=1.65),radiotherapy (OR=2.65),SPSS (OR=1.55),chemotherapy (OR=1.85) were the risk factors for nutritional status (P＜ 0.05).Conclusions The incidence of nutritional risk is high in elderly prostate cancer patients.Age,sleep quality are the protective factors,and operation,pathology staging,SPSS,chemotherapy,and radiotherapy are the risk factors for nutritional status.

Objective:To screen the kinase genes related to radioresistance by high-throughput method and provide a theoretical basis for clinical treatment strategy of oral squamous cell carcinoma.Methods:The tongue squamous carcinoma cell line Cal-27 was infected with lentivirus shRNA kinase library that contains 4 675 different shRNAs regulating 709 human kinase genes. The uninfected cells were removed by puromycin screening. Then, the cells were irradiated with different doses (0, 10, 15 cGy) and continued to culture for 3 d to enrich the differences among groups. Afterwards, the cell genomic DNA was extracted and the complete shRNA sequences were obtained by PCR.Different tags were labeled in shRNAs of each group. An illumina platform was used for next generation sequencing to acquire the shRNA abundance, and then the differentiated expressed genes among different groups were identified.Results:A total of 5 kinase genes (PKLR, IPMK, AURKB, ITPKB and DLG2) were screened out from irradiated cells. Knockdown of PKLR and IPMK increased radiation resistance, while knockdown of AURKB, ITPKB and DLG2 increased radiation sensitivity, and the high expression of these genes would lead to radiotherapy tolerance.Conclusions:In this study, 3 genes relative to radioresistance of oral squamous cell carcinoma were identified by using shRNA lentivirus library combined with next generation sequencing, but the underlying mechanism requires further exploration.

In August 2022, a patient diagnosed with PIK3CA-related overgrowth syndrome (PROS) was admitted to the Department of Burn and Plastic Surgery of the General Hospital of Eastern Theater Command. A 15-year-old male patient presented with overgrowth of the left lower limb since birth, which had progressive aggravation six months ago, accompanied by erythema and dilated veins (42 cm ×24 cm) on the left waist. MRI showed that the soft tissue of the left and right thighs was asymmetrical. There was soft tissue hypertrophy of the left thigh, vascular malformation on the left waist and a left renal cyst. The vascular malformations on the left waist were treated by sclerotherapy with 3% polydocaol injection, for which the injection volume of was 7.1 ml. Immunohistochemistry of the pathological tissue showed that PIK3CA, AKT and mTOR were positive in vascular endothelial cells and epidermal basal cells. The genetic testing suggested that there was a mutation at c. 3190_3191insA (p.H1065fs) in PIK3CA gene. On the first year after the interventional sclerotherapy, the area of erythema decreased and the overgrowth of the left lower limb did not progress significantly. This case was diagnosed by clinical manifestations, pathological examination and genetic testing, which expanded the clinical phenotype of PROS and PIK3CA mutation spectrum, providing relevant clinical data for the study of this diseases.

Angiostrongylus cantonensis invades the central nervous system (CNS) of humans to induce eosinophilic meningitis and meningoencephalitis and leads to persistent headache, cognitive dysfunction, and ataxic gait. Infected mice (nonpermissive host), admittedly, suffer more serious pathological injuries than rats (permissive host). However, the pathological basis of these manifestations is incompletely elucidated. In this study, the behavioral test, histological and immunohistochemical techniques, and analysis of apoptotic gene expression, especially caspase-3, were conducted. The movement and motor coordination were investigated at week 2 post infection (PI) and week 3 PI in mice and rats, respectively. The cognitive impairs could be found in mice at week 2 PI but not in rats. The plaque-like lesion, perivascular cuffing of inflammatory cells, and dilated vessels within the cerebral cortex and hippocampus were more serious in mice than in rats at week 3 PI. Transcriptomic analysis showed activated extrinsic apoptotic pathway through increased expression of TNFR1 and caspase-8 in mice CNS. Immunohistochemical and double-labeling for NeuN and caspase-3 indicated the dramatically increased expression of caspase-3 in neuron of the cerebral cortex and hippocampus in mice but not in rats. Furthermore, western-blotting results showed high expression of cleaved caspase-3 proteins in mice but relatively low expression in rats. Thus, extrinsic apoptotic pathway participated in neuronal apoptosis might be the pathological basis of distinct behavioral dysfunctions in rodents with A. cantonensis infection. It provides the evidences of a primary molecular mechanism for the behavioral dysfunction and paves the ways to clinical diagnosis and therapy for A. cantonensis infection.

Objective: To explore the spatial distribution of low birth weight (LBW) and the potential environmental risk factors and provide the evidence for the prevention and intervention of LBW. Methods: Data were from a surveillance system for newly born population and adverse pregnancy outcome between 2007 and 2012 in Pingding county, Shanxi province. The data from 313 villages were analyzed. Spatial hierarchical Bayesian model was used to adjust the risk of LBW at village level, Moran’s I and Getis-Ord Gi* were used to analyze the difference in distribution of LBW risk area. Spatial negative binomial model was used to evaluate the association between the risk of LBW and chemical fertilizer application. Results: A total of 18 749 new births were recorded between 2007 and 2012, including 911 LBW cases, the total incidence of LBW was 4.86%. The result of the spatial hierarchical Bayesian model showed that high-risk area of LBW was in the southeast of Pingding and low-risk area was in the middle west of Pingding. The result of Moran’s I showed that there was a clustering pattern of LBW risk, and Getis-Ord Gi* found a high risk (hot spot) area in the south area. Moreover, the findings of association analysis showed that the risk of LBW increased with the increased chemical fertilizer application at village level. Conclusions There were area specific differences in the risk of LBW, and dose-response relationship between chemical fertilizer application and the risk of LBW. Our findings suggest that maternal exposure to chemical fertilizer during pregnancy might be a potential risk factor for LBW in rural area.

Objective The existing evidence of exercise rehabilitation in patients undergoing surgery for valvular heart disease was analyzed,described and evaluated by using evidence mapping methods.Methods Systematic reviews and randomized controlled trials on exercise rehabilitation of patients undergoing valvular heart disease surgery were searched from CNKI,Wanfang Data,VIP,CBM,Embase,PubMed,Cochrane Library,Web of Science,Ovid,CINAHL and other databases,and the search period was established until April 23,2024.The quality of the included literature was evaluated,and the feature information of the included literature was visualized in the form of bubble map and table.Results Fifty-one literatures(including 44 randomized controlled trials and 7 systematic evaluations)were finally included.Among the 44 randomized controlled trials,the types of exercise were mainly related to anaerobic exercise(3 literatures),aerobic exercise(11 literatures),flexibility training(8 literatures),and multisport exercise(22 literatures);postoperative inpatient rehabilitation accounted for a relatively high proportion(16 literatures),followed by overall postoperative rehabilitation(13 literatures)and pre-operative prehabilitation(7 literatures).Twenty-seven conclusions were categorized as"beneficial",15 as"possibly beneficial,"and one ach as"unclear"and"no effect".Seven systematic evaluations were subjected to Meta-analysis,and in terms of the design of the included studies,there were only 3 systematic reviews that included randomized controlled trials.Of the study conclusions,three were"beneficial",three were"possibly beneficial"and one was"unclear".Conclusion The evidence mapping shows that exercise rehabilitation is generally beneficial or potentially beneficial in the rehabilitation of valvular heart disease surgery,mainly in the postoperative inpatient rehabilitation phase.High-quality studies are needed to further investigate the effectiveness of exercise programs with different intensities,frequencies,and durations,as well as different valve types,adverse effects of exercise,and other outcome indicators.

Objective To evaluate the effect of mindfulness-based intervention in patients after percutaneous coronary intervention(PCI)through Meta-analysis.Methods Nine databases,including CNKI and PubMed,were searched for randomized controlled trials on the effect of mindfulness intervention in patients after PCI,and the search period was from the establishment of the database to May 31,2024.Two researchers independently screened the literature,extracted data and evaluated the quality,and used Revman 5.4 software for Meta-analysis.Results A total of 11 randomized controlled trials involving 998 patients were included.The results of Meta-analysis showed that compared with conventional care,the use of mindfulness-based intervention therapy could positively improve patients'postoperative anxiety,perceived stress level,mindfulness awareness and other indicators.In terms of safety measures,the incidence of cardiac adverse events was not statistically significant compared with usual care(P＞0.05).Conclusion Mindfulness intervention has a significant effect in patients after PCI.

Objective To explore the clinical and genetic characteristics of 17α-hydroxylase/17,20-lyase deficiency(17OHD)in childhood.Methods The clinical features,laboratory and imaging examination results,gene mutation characteristics of 4 children diagnosed with 17OHD in Children's Hospital Affiliated to Zhengzhou University from January 2016 to December 2022 were retrospectively analyzed,and the literature was reviewed and summarized.Results At the time of diagnosis,the age of 4 children ranged from 11 months and 21 days to 10 years and 6 months.All patients had karyotypes of 46,XY.Social gender:1 male and 3 females.The chief complaints were 1 case of short penis,1 case of inguinal mass,and 2 cases of grade 2 hypertension,and 3 cases of testes were found in scrotum,groin and inguinal annulus,respectively.The levels of cortisol,testosterone,and androstenedione decreased at 8 o'clock in 4 children,while the levels of adrenocorticotropic hormone,progesterone,luteinizing hormone,and follicle stimulating hormone increased.17 hydroxyprogesterone was normal.Mild decrease in blood potassium levels(3.44-3.48 mmol/L)was found in 3 cases.One case of CYP17A1 homozygous mutation and three cases of compound heterozygous mutation were found,among which c.563 A＞G and c.436+1G＞T were new mutation sites that had not been reported in the past,and 3 cases had c.985_987delinsAA mutation.All 4 cases received oral hydrocortisone treatment.Conclusions Abnormal external genitalia,inguinal/labial mass and hypertension are the main features of 46,XY type 17OHD in childhood.Early hydrocortisone replacement therapy can effectively prevent the complications of 17OHD.The CYP17A1 c.985_987delinsAA mutation may be a hot topic mutation in children with 17OHD in China.

Objective:To investigate the relationship between triglyceride glucos (TyG), C-reaction protein/albumin (CRP/Alb), 25-hydroxy vitamin D[25(OH)D] and the prognosis of patients with continous ambulatory peritoneal dialysis (CAPD).Methods:A total of 220 CAPD patients in the Affiliated Hospital of Jining Medical University from January 2017 to March 2020 were prospectively selected and divided into death group and survival group according to the 6-month prognosis. The peritoneal urea clearance index (Kt/V urea), TyG, CRP/Alb, 25(OH)D were compared between the two groups. Logistic regression was used to analyze the prognostic factors of CAPD patients. The predictive value of TyG, CRP/Alb and 25(OH)D on the prognosis of CAPD patients was analyzed by receiver operating characteristic (ROC) curve. Results:After 3 months and 6 months of dialysis, the peritoneal Kt/V urea in the death group [(1.21±0.18)ml/(s·1.73 m 2), (1.02±0.14)ml/(s·1.73 m 2)] was significantly lower than that in the survival group [(1.57±0.40)ml/(s·1.73 m 2), (1.49±0.42)ml/(s·1.73 m 2)] (all P<0.05). After 3 months and 6 months of dialysis, the TyG [(8.79±0.86), (9.24±1.03)] and CRP/Alb [(4.98±0.94)×10 -4, (5.14±1.39)×10 -4] in the death group were higher than those in the survival group [(8.03±0.60), (7.26±0.93), (3.57±1.19)×10 -4, (3.07±0.88)×10 -4], while the 25(OH)D [(19.14±2.29)ng/ml, (17.79±3.17)ng/ml] was lower than that of survival group [(22.67±3.03)ng/ml, (24.31±2.51)ng/ml] (all P<0.05). TyG and CRP/Alb at 3 months and 6 months of dialysis were negatively correlated with Kt/V urea, while the 25(OH)D was positively correlated with Kt/V urea (all P<0.05). Logistic regression analysis showed that Kt/Vurea, TyG, CRP/Alb and 25(OH)D were associated with prognosis in the two groups after 3 and 6 months of dialysis (all P<0.05). The AUC of TyG, CRP/Alb and 25(OH)D at 6 months of dialysis combined to predict the prognosis of CAPD patients was the highest, which was 0.911. Conclusions:TyG, CRP/Alb and 25(OH)D are associated with all-cause mortality in CAPD patients. High TyG and CRP/Alb and low 25(OH)D suggest a higher risk of all-cause mortality. Combined detection of all indicators can effectively predict the prognosis of CAPD, which is convenient for early clinical intervention.
