Objective To explore the relationships among post traumatic stress disorder(PTSD),gratitude and posttraumatic growth (PTG) for terminal cancer patients.Methods Totally 119 advanced cancer patients were investigated with the self-demographic questionnaire,posttraumatic growth inventory (PTGI),the PTSD cheeklist-civilian version (PCL-C) and the Gratitude Questionnaire-6 (GQ-6).Results For terminal cancer patients,the total score of PCL-C was 34.02±12.49.The scores on re-experience,avoidance/numbness,hypervigilance were 9.79±3.78,13.85±5.68,10.36±3.80.The total score of gratitude was 29.37±7.48.The total score of PTG was 51.34± 13.57.The scores of life appreciation,personal relationship and self-strength were 8.00± 2.99,21.18± 5.84,22.16± 6.10.The total scores of PTG were significantly statistical significance among different PTSD groups(F=16.267,P＜0.01)and gratitude groups(F=43.674,P＜0.0 1).The total scores of PCL-C (r=-0.694,P＜0.01),re-experience (r=-0.664,P＜0.01),avoidance/numbness (r=-0.671,P＜0.01),hypervigilance (r=0.753,P＜0.01) and gratitude(r=-0.611,P＜0.01) were all correlated with PTG.The total score of PCL-C and gratitude could explain 66.6％ variation of PTG.For the relationship between PTSD and PTG,the moderation effect of gratitude was not significant (P ＞0.05).Conclusion The gratitude and PTSD were important influence factors for terminal cancer patients' PTG,while the moderation effect of gratitude was not significant,so in clinical intervention we should pay more attentions to the actual effects of gratitude,and we should not pursuit gratitude education blindly.

Objective:The occurrence of numerous tumors, particularly classical Hodgkin's lymphoma (CHL), is related with Ep-stein-Barr virus (EBV) infection. However, the incidence of CHL and its association with EBV varies significantly with ethnicity, geo-graphic location, sex, and age. This study investigated the association of EBV infection with CHL in Northern Chinese Han population. Methods:EBV-encoded small RNA (EBER) was detected in 136 cases of CHL through in situ hybridization. Results:A total of 37 cas-es were EBER positive (28%). The mixed cellularity (MC) subtype had the highest positive EBER rate of 49%(23/47;P<0.001), fol-lowed by lymphocyte-rich subtype with 30%(3/10), nodular sclerosis (NS) subtype with 14%(10/73), and 1ymphocyte depletion with 0%(0/2). Our study identified a single age distribution in the third decade. Moreover, NS subtype showed an evident single peak in the third decade. However, MC subtype had a lower peak in the fifth decade. The incidence of EBER showed a bimodal age distribution with two peaks in the first and fifth decades (21.6%and 24.3%, respectively). Conclusion:CHL in Northern Chinese Han population was associated with EBV infection, particularly the MC subtype.

Objective: To investigate the hot spots and epidemiologic characteristics of hand, foot and mouth disease (HFMD) in Jinan municipality from 2009 to 2016. Methods: Disease reports of HFMD in Jinan from 2009-2016 were collected and analyzed with ArcGis 10.2 to show the hot spot in different villages and towns, as well as clustering analysis and descriptive epidemiology to show epidemiologic characteristics. Results: A total of 89 486 HFMD cases were reported and the reported annual incidence rate was 160.94/100000 during the 7-year period, which increased year by year, and within the whole city, each county was at a higher epidemic level; the curve of incidence is unimodal and the incidence peak occurred mostly between May and August, especially in June; 115 severe cases were reported and the ratio was 0.13%. Of the reported cases, 81.51% were between 1 to 4 years old; 60.36 % were children living scattered. The hot spots were like a circle surrounding the core areas, showing a tendency of increase; the proportion of EV71, CVA16 and other enteroviruses were 33.67%、37.22%and 29.09%, respectively, and they appeared in turn, but severe cases were mostly affected by EV71. Conclusions The HFMD in Jinan is in a highly prevalent level, with low ratio of severe cases. Seasonal(high in summer) and unimodal; more common among children between 1 to 4 years old, living scatted and in urban and rural linking areas, with the tendency of increasing of hot spots; prevalent pathogens appear in turn.

Objective To evaluate the clinical application value of reflectance confocal microscopy(RCM) in the diagnosis of several common diseases manifesting as papules in children, including lichen nitidus, verruca planae, lichen striatus, milium, molluscum contagiosum and lichen pilaris. Methods A total of 579 children clinically characterized by papules were recruited into this study. RCM was used to observe lesions and perilesional normal skin. The RCM features of 6 diseases manifesting as papules were analyzed and compared. Results Based on RCM images, 236 patients were diagnosed with lichen nitidus, 70 with verruca planae, 123 with lichen striatus, 40 with milium, 53 with molluscum contagiosum and 57 with lichen pilaris. All the 6 diseases had typical RCM features. Concretely speaking, RCM images of lichen nitidus lesions showed infiltration of dense inflammatory cells and melanophages in enlarged dermal papillae. In RCM images of verruca planae lesions, cells in the granular and spinous layers were arranged in concentric circles, giving a rose cluster?like appearance. RCM images of lichen striatus lesions revealed focal swelling of stratum spinosum, absent or local liquifaction degeneration of basal cells, and clustering of a moderate number of inflammatory cells in the superficial dermis. In RCM images of milium lesions, well?circumscribed round or oval structures containing highly but nonuniformly refractive materials could be seen in the dermis. RCM images of molluscum contagiosum lesions showed intact cystoid structures containing highly refractive molluscum bodies. Lowly to moderately refractive cutin ? like materials were observed along with the dilation of hair follicle infundibula in RCM images of lichen pilaris lesions. In RCM images, the 6 diseases were distinguished mainly based on structural features(patterns and refractivity)of skin lesions shown by continuous vertical scanning. Conclusion RCM is of great value to the diagnosis of diseases manifesting as papules in children.

Objective To study the effect of masked hypertension (MH) and white coat hypertension (WCH) on vascular elasticity and endothelial function in elderly patients.Methods Four hundred and eighty-seven elderly patients who underwent physical examination in our our hospital were divided into normotension group (n=128),WCH group (n=115),MH group (n=112) and hypertension group (n=132) according to their diagnostic office blood pressure and 24 h ambulatory blood pressure.The brachial artery FMD,serum NO and endothelin-1 (ET-1) levels,and cfPWV were measured.Results The FMD and serum NO level were significantly lower while the serum ET-1 level and cfPWV were significantly higher in WCH group,MH group and hypertension group than in normotension group (P＜0.05).The FMD and serum NO level were significantly higher while the serum ET-1 and cfPWV were significantly lower in WCH group and MH group than in hypertension group (P＜ 0.05).Multivariate linear stepwise regression analysis showed that WCH,MH and hypertension were the independent influencing factors for FMD,serum NO and ET-1 level and cfPWV with normotension used as reference after adjustment of confounding factors (P＜0.01).Conclusion MH and WCH are the risk factors for the decreased vascular elasticity and endothelial dysfunction in elderly patients.

Objective To study the association between morning surge (MS) of systolic blood pressure (SBP) and white matter lesions in elderly essential hypertensive (EH) patients.Methods Three hundred and thirty-seven elderly EH patients from Zhangqiu of Shandong Province were divided into MS group (n=150) and non-MS group (n=187).Their 24 h ambulatory SBP was monitored.Their white matter hyperintensity (WMH) was assessed according to their brain MRI.Results The total WMH,periventricular WMH,and deep WMH were significantly higher in MS group than in non-MS group (P＜0.01).The MS of SBP was positively related with the total WMH,periventricular WMH,and deep WMH (r=0.561,r=0.563,r=0.283,P＜0.01),and was an independent risk factor for total WMH,periventricular WMH,and deep WMH after adjustment for confunders (r=0.479,r=0.486,r=0.208,P＜0.01).Conclusion MS of SBP is an independently risk factor for WMH in elderly EH patients.

Objective:To analyze the imaging characteristics of Stanford B aortic dissection in aortic CT angiography, in order to explore the possible related factors of aortic dissection combined with renal malperfusion and to analyze the morphological changes in each involved vessel after TEVAR.Methods:From January 2018 to December 2019, totally 148 patients of Stanford B aortic dissection underwent TEVAR in our hospital. The preoperative aortic CTA was analyzed, and all cases complicated with renal malperfusion were determined according to the clinical manifestation, laboratory examination and imaging results. The differences of morphological features between the patients with and without renal malperfusion and the possible correlative factors were analyzed.The different ischemic types of the involved renal arteries were analyzed, and the morphological changes of the involved vessels before and after the operation of TEVAR were compared.Results:The logistic regression analysis showed that the concave configuration of the tear at the renal artery level was the independent risk factor for renal malperfusion (right kidney OR=5.319, P=0.032; left kidney OR=12.879, P=0.007). The diameter of renal artery was the independent protective factor for renal malperfusion (right kidney OR=0.464, P=0.018; left kidney OR=0.685, P=0.016). Compared with preoperative CTA, the diameter of the involved renal artery was significantly enlarged after TEVAR, no matter which type of ischemia. Most of the dynamic ischemia (15/16) was improved after TEVAR; while static and mixed ischemia only partially improved after TEVAR (static 22/36, mixed 11/19) . Conclusion:The concave configuration of the renal artery level, and the diameter of renal artery are associated with renal malperfusion.The malperfusion can be improved in most cases of dynamic ischemia type vessels, while only can be partially improved in static and mixed types vessles.

Objective To explore the characteristics of opportunistic infections(OIs)in HIV-infected indi-viduals with suboptimal immune reconstitution after ART treatment so as to provide a reference for preventing and managing HIV infections.Methods The clinical data including opportunistic infections specifically were acquired from 112 HIV-infected individuals with suboptimal immune reconstitution from the outpatient department of Wuming Hospital,Guangxi Medical University.The impact of baseline CD4+T lymphocyte counts on the incidence,type,and mixed infection rates of the opportunistic infections were analyzed.Results The opportunistic infection rate among the 112 HIV-infected individuals with suboptimal immune reconstitution was 42.86%,among which fungal infections were the most commonly seen.The opportunistic infection rate of the patients with a baseline of CD4+T lymphocyte counts≤50/μL was significantly higher than that of the patients with a baseline of CD4+T lymphocyte counts>50/μL,and there was no significant difference in the type of opportunistic infections as well as the rate of mixed infections.Conclusion HIV-infected people with suboptimal immune reconstitution in Guangxi are susceptible to HIV OIs.Among them,the group with a baseline CD4+ T lymphocyte counts≤50/μL has a higher rate of OIs,mainly fungal infections.

Objective To investigate the geographical distribution and seasonal fluctuations of visceral leishmaniasis vectors sandflies in Henan Province in 2023, so as to provide insights into the prevention and control of visceral leishmaniasis vectors. Methods A total of 23 counties (districts) were sampled from 18 cities of Henan Province from May to September, 2023 as sandfly surveillance sites, and sandflies were captured using human capture and light trapping methods. Following morphological identification, the changes in the sandfly density were calculated at different months and in different breeding habitats. Results A total of 406 light traps were set at sandfly surveillance sites in Henan Province from May to September, 2023, and a total of 3 137 female sandlies were captured, with an average density of 7.73 sandlies/(light·night). A total of 1 494 Phlebotomus chinensis sandflies were captured, including 1 222 female sandflies, with an average density of 3.01 sandflies/(light·night), and the highest density of P. chinensis was found in Gongyi City [17.00 sandflies/(light·night)]. A total of 5 544 sandflies were captured using the human capture method, including 230 P. chinensis, and the density of P. chinensis appeared a unimodal distribution, with a peak in early July [5.81 sandflies/(light·night)]. Among different breeding habitats, the highest P. chinensis density was detected in pigpens [4.50 sandflies/(light·night)]. Conclusions P. chinensis was predominantly distributed in hilly areas of northern and central-western Henan Province in 2023, and the sandfly density appeared a unimodal distribution. Intensified monitoring of visceral leishmaniasis vectors is recommended.
