Objective:To investigate the effect of mucosal thickness around implants on marginal bone resorption.Methods:A retrospective analysis was conducted on the clinical data of 75 patients who received single-tooth implant restorations at Shaoxing Stomatological Hospital from December 2020 to May 2022. The patients were divided into two groups based on mucosal thickness: the thin gingiva group ( n = 40) and the thick gingiva group ( n = 35). In the thin gingiva group, implants were placed 1.5 mm below the bone surface, while in the thick gingiva group, implants were placed at the bone surface. Implant survival rates, marginal bone resorption, bone remodeling, and the incidence of adverse reactions were compared between the two groups. Results:The implant survival rate in the thin gingiva group was significantly lower than that in the thick gingiva group [75.00% (30/40) vs. 94.29% (33/35), χ 2 = 5.17, P < 0.05]. After 9 months of weight bearing, marginal bone resorption value in the thin gingiva group was significantly higher than that in the thick gingiva group [(0.16 ± 0.04) vs. (0.14 ± 0.02), t = 2.83, P < 0.05]. The bone remodeling value in the thin gingiva group was significantly lower than that in the thick gingiva group [(1.03 ± 0.21) vs. (1.25 ± 0.34), t = 3.48, P < 0.05]. The incidence of adverse reactions including infection, bleeding, occlusal weakness, and pain in the thin gingiva group was significantly higher than that in the thick gingiva group [25.00% (10/40) vs. 5.72% (2/35), χ 2 = 5.17, P < 0.05]. Conclusion:A mucosal thickness of ≥ 3 mm is associated with a higher survival rate of implants placed below the bone surface, which better maintains bone tissue stability, reduces bone resorption, promotes bone remodeling, and decreases the incidence of adverse reactions.

Background::Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) can profoundly affect the mental health of the people living with HIV (PLWH), with higher rates of anxiety, depression, and sleep disturbances. The disparities in neuropsychological problems evaluated by physicians and self-assessed by patients are still unknown.Methods::A total of 5000 PLWH and 500 physicians from 167 hospitals were enrolled in this cross-sectional study from September 2022 to February 2023. 4-Item Patient Health Questionnaire (PHQ-4) was used for the evaluation of depressive issues and anxiety issues by PLWH. Each physician assessed 10 PLWH under their care for the presence of depressive or anxiety issues. The primary outcomes of this study are the concordance rates on the depressive issues and anxiety issues evaluation between physicians and PLWH. The Cohen’s kappa test was used to assess the agreement between physicians and PLWH.Results::The concordance rate for the evaluation of depressive issues is 73.84% (95% confidence interval [CI]: 72.60-75.04%), and it is significantly different from the expected rate of 80% ( P <0.001). Similarly, the concordance rate for the evaluation of anxiety issues is 71.74% (95% CI: 70.47-72.97%), which is significantly different from the expected rate of 80% as per the null hypothesis ( P <0.001). The overestimation rate by physicians on depressive issues is 12.20% (95% CI: 11.32-13.14%), and for anxiety issues is 12.76% (95% CI: 11.86-13.71%). The mismatch rate for depressive issues is 26.16% (95% CI: 24.96-27.40%), and for anxiety issues is 28.26% (95% CI: 27.02-29.53%). The underestimation rate by physicians on depressive issues is 13.96% (95% CI: 13.03-14.95%), and for anxiety issues is 15.50% (95% CI: 14.52-16.53%). For the treatment regiments, PLWH sustained on innovative treatment regimen (IR) related to a lower prevalence of depressive issues (odds ratio [OR] = 0.71, 95% CI: 0.59-0.87, P = 0.003) and a lower prevalence of anxiety issues (OR = 0.63, 95% CI: 0.52-0.76, P <0.001). PLWH switch from conventional treatment regimen (CR) to IR also related to a lower prevalence of depressive issues (OR = 0.79, 95% CI: 0.64-0.98) and a lower prevalence of anxiety issues (OR = 0.81, 95% CI: 0.67-0.99). Conclusion::Nearly one in three PLWH had their condition misjudged by their physicians. The findings underscore the need for improved communication and standardized assessment protocols in the care of PLWH, especially during the acute phase of HIV infection.

Purpose: The epidemiology of B-cell non-Hodgkin lymphoma (BNHL) in Asia is not well described, and rates of second primary malignancies (SPM) in these patients are not known. We aimed to describe temporal changes in BNHL epidemiology and SPM incidence in Korea. Materials and Methods: A retrospective cohort study used claims data from the National Health Insurance Service that provides universal healthcare coverage in Korea. Newly diagnosed patients aged at least 19 years with a confirmed diagnosis of one of six BNHL subtypes (diffuse large cell B-cell lymphoma [DLBCL], small lymphocytic and chronic lymphocytic [CLL/SLL], follicular lymphoma [FL], mantle cell lymphoma [MCL], marginal zone lymphoma [MZL], and lymphoplasmacytic lymphoma/Waldenström’s macroglobulinemia [WM]) during the period 2006-2015 were enrolled and followed up until death, dis-enrolment, or study end, whichever occurred first. Patients with pre-existing primary cancers prior to the diagnosis of BNHL were excluded. Results: A total of 19,500 patients with newly diagnosed BNHL were identified out of 27,866 with non-Hodgkin lymphoma (NHL). DLBCL was the most frequently diagnosed subtype (41.9%-48.4% of NHL patients annually, 2011-2015). Standardized incidence of the six subtypes studied per 100,000 population increased from 5.74 in 2011 to 6.96 in 2015, with most increases in DLBCL, FL, and MZL. The incidence (95% confidence interval) of SPM per 100 person-years was 2.74 (2.26-3.29) for CLL/SLL, 2.43 (1.57-3.58) for MCL, 2.41 (2.10-2.76) for MZL, 2.23 (2.07-2.40) for DLBCL, 1.97 (1.61-2.38) for FL, and 1.41 (0.69-2.59) for WM. Conclusion BNHL has been increasingly diagnosed in Korea. High rates of SPM highlight the need for continued close monitoring to ensure early diagnosis and treatment.

Objective: A more safe and efficient "classification" items validity management method is proposed through the comparative analysis of the merits and demerits of the common items validity management methods, combined with the exploration and practice of the gynaecological ward of a specialized hospital in Shanghai, Methods: The "classification" item validity management method includes setting up a special task group and formulating a work flow. The critical point is to adopt different management methods according to the classification of items. Results: According to the supplier of items, it is divided into Class I and Class II. Items of Class I adopt the management method of validity turnover rate and Class II items adopt the effective period safety area management method. Conclusion The validity management method of "classification" items ensures the quality of special task and improves the work efficiency.

Objective To investigate the clinical efficacy and toxicity in the use of simultaneous integrated boost intensity modulated radiation therapy (SIB-IMRT) for inoperable locally advanced nonsmall cell lung cancer (LA-NSCLC).Methods Between February 2012 and July 2015,58 pathologically diagnosed inoperable LA-NSCLC patients treated with SIB-IMRT were analyzed.A radiation dose of 50-64 Gy was administered in 1.8-2.2 Gy/fraction (26-30 fractions) to the planning target volume (PTV).Simultaneously,60-70 Gy was administered in 2.0-2.35 Gy/fraction (26-30 fractions) to the planning gross tumor volume (PGTV).Results The median follow-up time was 28.0 months (ranging from 6.0 to 40.0 months).The median overall survival (OS) and progress-free survival (PFS) were 25.0 (95％ CI:23.8-26.2) and 15.0 (95％ CI:11.3-18.7) months,respectively.The 1-,2-year OS were 91.4％ and 51.7％,respectively.The 1-,2-year PFS were 56.9％ and 22.7％,respectively.None of the patients developed grade 4 or 5 pneumonitis and esophagitis.In addition,in the subgroup analysis,the patients with N3 have a higher incident of ≥ grade 2 esophagitis compared with N0-N2,the incident are 29.2％ and 20.6％,respectively (P ＜ 0.05).Conclusions SIB-IMRT is feasible and well-tolerated for inoperable LA-NSCLC patients.It remains to be further evaluated in a large sample size prospective clinical trial.

Objective To compare the curative effect of arthroscopic transtibial single-bundle posterior cruciate ligament(PCL) reconstruction using LARS artificial ligament and hamstring tendon autograft.Methods Thirty-seven patients who underwent isolated single-bundle PCL reconstruction with remnant preservation technique were evaluated.They were divided into LARS group(n=19) and 4-strand hamstring tendon autograft (4SHG) group (n =18).Minimum follow-up was 2 years.Patients were evaluated preoperatively and postoperatively at the latest follow-up with several parameters,including the international knee documentation committee(IKDC) score,Lysholm knee score,Tegner activity rating and physical examination.Results After operation,in LARS group,Lysholm sorce was 89 (51,100) points,Tegner sorce was 6 (1,9) points,IKDC sorces were normal of 5 cases,nearly normal of 10 cases,abnormal of 3 cases,and obviously abnormal of 1 case,significantly improved compared with before operation (62 (28,98) points,2 (1,5) points,abnormal IKDC score of 8 cases,obviously abnormal of 11 cases;P＜0.001).In 4SHG group,Lysholm sorce was 84(36,100) points,Tegner sorce was 6(1,9) points,IKDC sorces were normal of 5 cases,nearly normal of 9 cases,abnormal of 3 cases,and obviously abnormal of 1 case,better than before operation (64 (28,98) points,2 (1,5) points,IKDC score abnormal of 8 cases,obviously abnormal of 10 cases;P＜0.001).There was significant difference about Lysholm sorce between two groups after operation (P=0.037).The drawer test results show that,after operation,there were 15 case of grade 0,4 cases of grade 1 in LARS group,3 cases of grade 0,11 cases of grade 1,4 cases of grade 2 in 4SHG group,all improved significantly compared with before operation,and the differences were statistically significant(LARS group:x2 =38.000,P＜0.001;4SHG group:x2 =29.143,P＜0.001),and the grade of patients in LARS group were superior to 4SHG group after operation (x2 =15.251,P ＜0.001).Conclusion The clinical effect of using a LARS ligament for PCL reconstruction is more useful than using a 4SHG.

Nasopharyngeal cancer (NPC) is an Epstein–Barr virus-associated malignant tumor. Radiation alone or concurrent chemo-radiotherapy is the principal treatment method and can generally achieve excellent efficacy for NPC patients. However, the prognosis of locoregionally advanced disease or distant metastasis remains poor. Currently, immunotherapy has become a new treatment of sol-id tumors, and it is mainly activating the antitumor immune system of the body. The review aims to explore the progress of immuno-therapy, including adoptive immunotherapy, tumor vaccines, and immune checkpoint inhibitors in NPC treatment.

Objective To explore the change of copeptin in plasma and its significance in patients with intracerebral hemorrhage combined with stress ulcer.Methods Eighty patients with intracerebral hemorrhage were collected.Forty-nine patients of pure intracerebral hemorrhage and 31 patients of intracerebral hemorrhage combined with stress ulcer were included.Thirty healthy people were taken as controls.The level of copeptin in plasma was measured and compared in all subjects.Results The level of copeptin in plasma in patients with pure intracerebral hemorrhage and intracerebral hemorrhage combined with stress ulcer was significantly higher than that in controls:(303.684 ± 68.691),(527.034 ± 74.111) ng/L vs.(121.460 ± 53.364) ng/L,and the level of copeptin in plasma in patients with intracerebral hemorrhage combined with stress ulcer was significantly higher than that in patients with pure intracerebral hemorrhage.The differences were statistically significant (P ＜ 0.05).Conclusion The level of copeptin in plasma in patients with pure intracerebral hemorrhage increases significantly,and it is much higher in patients with intracerebral hemorrhage combined with stress ulcer.

PurposeThe bone flare phenomena has been well described on bone scintigraphy for efficacy monitoring up to now, but our knowledge has been rarely described on MSCT, the phenomena may be erroneously classiifed as disease progression. This article intends to evaluate the existence and CT features of bone flare phenomena of metastatic bone disease in lung cancer patients treated with ibandronate, to raise awareness of this phenomenon.Materials and Methods The clinical and image data of 45 patients with bone metastases of lung cancer were retrospectively analyzed prior to treatment and 3, 6 months after treatment, the change of CT value and CT features 3 months after treatment between bone flare phenomena group, progressive disease group 1 and progressive disease group 2 were compared.Results The incidence of bone flare phenomena was 6.7% (3/45). 3 months after treatment, CT value of the bone flare phenomena group and progressive disease group 1 changed when compared with before treatment, the differences were statistically signiifcant (t=-5.787 and-2.788,P<0.05) and there was no statistically signiifcant difference (t=1.691,P>0.05) of CT value in the progressive disease group 2 after 3 months' treatment. After 3 months' treatment, the bone flare phenomena group mostly appeared as osteogenic sclerosis of osteolytic lesions, while the cases of progressive disease group mostly appeared as new periosteal reaction of the lesion, or osteogenic/mixed lesion combined with osteolytic damages, the difference between the two groups was statistically signiifcant (χ2=10.139, 8.041 and 4.154,P<0.01,P<0.05). There was no statistically signiifcant difference in increase of density in osteosclerotic lesions (χ2=0.059, P>0.05).Conclusion In patients treated with ibandronate, when there is therapeutic effect evaluation standard of bone metastases (disease progression) and clinical comprehensive curative effect evaluation standard (effective) discordance at 3 months after treatment, it can be interpreted as bone flare phenomena, and the change of CT features contributes to the differential diagnosis of bone flare phenomena with progressive disease.
