Objective : To systematically evaluate the incidence of suicide ideation among HIV/AIDS patients in China, so as to provide insights into prevention of suicidal behaviors among HIV/AIDS patients. Methods : All publications pertaining to suicide ideation were jointly retrieved in electronic databases from database creation to May 22, 2022, including CNKI, CMB, Wanfang Data, VIP, PubMed and Web of Science. The quality of literatures was evaluated using the 11 quality indicators for cross-sectional studies recommended by the United States Agency for Healthcare Research and Quality (AHRQ), and a meta-analysis was performed using the software Stata 16.0. The stability of the study results was evaluated using sensitivity analysis, and the publication bias was evaluated using Begg's test. Results : A total of 1 557 publications were screened and 32 literatures covering 12 917 HIV/AIDS patients were included in the final analysis, including 21 Chinese publications and 11 English publications, and 19 high-quality publications and 13 moderate-quality publications. Meta-analysis showed that the incidence of suicide ideation was 30.3% (95%CI: 23.2%-37.4%) among HIV/AIDS patients in China, and subgroup analysis showed higher incidence of suicide ideation in unemployed HIV/AIDS patients than in employed patients (P<0.05). Sensitivity analysis showed stable study results, and Begg's test revealed no significant publication bias. Conclusions The incidence of suicide ideation is 23.2% to 37.4% among HIV/AIDS patients in China. High attention paid to psychological health and early psychological interventions are required to prevent the development of suicide ideation.

Objective To evaluate the efficacy and safety of prophylactic cefiazidime on early bacterial infection in APBSCT recipients during neutropenia.Methods APBSCT recipients were prospectively randomly assigned to intravenous ceftazidime treatment group and control group (no prophylaxis of antibiotics).The treatment started from the first day until resolution of neutropenia or the appearance of early bacterial infection.Results From March 2010 to January 2013,70 APBSCT recipients were enrolled in the study with 36 in treatment and 34 in control group.Overall,29 (41.4％) patients developed early bacterial infection,among which,9(25.0％) in the treatment group and 20(58.8％) in the control group (P =0.004).The median infection free survival (IFS) was not reached in the treatment group and was 8 days in the control group (P =0.005).Despite whether patients received single high dose melphalan or other conditioning regimes,the early bacterial infection rate was lower in the treatment group than in the control group,and the median IFS was longer in the treatment group than that in the control group.The mean courses of antibiotic administration were (8.08 ± 2.03) days and (3.68 ± 3.56) days respectively in the treatment and control groups (P ＜ 0.001).However,the duration of empirical carbapenems were (1.67 ±3.03) days and (3.68 ±3.56) days respectively (P =0.013).There was no significant difference of antibiotics cost per patient between the two groups.Four patients in the treatment group had a transient elevated serum creatinine.Overall,no infection related mortality was observed in either group.Conclusions Prophylaxis of intravenous ceftazidime for APBSCT recipients is effective in preventing early bacterial infection with an acceptable toxicity and cost profile.However,it doesn't have effect on infection related mortality.Therefore,our results do not support the use of antibiotic prophylaxis for patients undergoing APBSCT.

ObjectiveTo observe the effect of reverse acupuncture by stages combined with facilitation techniques on motor function of stroke patients.Methods114 stroke patient were randomly divided into the treatment group (n=68) and control group (n=46). The patients of the treatment group were treated with reverse acupuncture by stages combined with facilitation techniques. Those of the control group were treated with general acupuncture combined with facilitation techniques. The period of treatment of two group was 30 days.ResultsAfter treatment, the scores of motor function and activities of daily living of the treatment group were significantly higher than that of the control group ( P<0.01).ConclusionThe reverse acupuncture by stages combined with facilitation techniques can obviously improve motor function of stroke patients.

Objective This study was to assess the three-dimensional gross tumor volume(GTV)motion of lung cancer caused by respiration using four-dimensional computed tomography(4DCT),and to analyze the influenee factors.Methotis Four-DCT scans of 22 lung focuses in 21 patients with lung cancer were analyzed.The gross tumor volume was contoured in all 10 respiration phases of 4DCT scans.The changes in volume of GTV,the 3D motion of the centroid,boundary of GTV and the 3D spatial motion vectors were calculated and the irdluenee factors were analyzed.Results The average change in volume of GTV was+14.3%(0.2%.42.5%)/-8.4%(0.4%-38.6%),the average movement amplitude of GTV centroid and GTV boundary were(0.18±0.12)cm,(0.20±0.16)cm,(0.53±0.59)cm and(0.42±0.23)cm,(0.41±0.22)cm,(0.57±0.70)cm in medio-lateral,vertro-dorsal,cranio-caudal(CC) direction,respectively.The CC movement was larger than other directions(Z=-2.12,P=0.034;Z:-2.10,P=0.035),and no significant difference was observed in 3D motion of GTV boundary(Z=-0.81.P=0.417;Z=-0.86,0.391).The CC motion of GTV eentroid in lower lobe was larger than that in upper lobe[(0.87±0.64)and(0.35±0.49)cm,(t=-2.12,P=0.047)],and no significant difference was found in other directions[(0.23±0.10)and(0.19±0.18)em(t=-0.49,P=0.629),(0.21±0.13)and(0.17±0.11)cm(t=0.76,P=0.460)].There was no correlation of the 3D movement and 3D spatial motion vector of GTV to the volume of GTV(r=-0.306,-0.062,-0.279,-0.300;P=0.189,0.796.0.234,0.199).Conclusions GTV motion of patients with lung cancer is individual,the CC movement is the moat obvious,using 4DCT to assess is comparatively accurate.The motion amplitude of lower lobe focuses is larger.No significant correlation of the GTV motion to the volume was observed.Larger sample study is needed to analyze the influence of adjacency to the GTV motion.

OBJECTIVE: To explore the antitumor activities of kushen (Sophora flavescens) flavonoids (KS-Fs) in vivo and in vitro. METHODS: Cell proliferation was assayed by using methyl thiazolyl tetrazolium (MTT) method. H22 hepatocellular carcinoma and S180 sarcoma were induced in ICR mice. Lewis lung carcinoma was induced in C57BL/6 mice. H460 and Eca-109 tumor were induced in Balb/c nude mice by injecting 5x10(5) or 5x10(6) tumor cells in the right flank, respectively. RESULTS: KS-Fs could inhibit the growth of a variety of human tumor cell lines (A549, SPC-A-1, NCI-H460, etc.) in vitro. The antitumor efficacies were confirmed in the mice models of H22, S180 and Lewis lung tumors and the nude mice models of human H460 and Eca-109 xenografted tumors. The oral or intravenous maximum tolerated dose of KS-Fs was more than 2.8 g/kg or 750 mg/kg respectively, far more than the oral medial lethal dose of kushen alkaloids (< or = 1.18 g/kg). No adverse reactions were observed. CONCLUSION: These results suggest that KS-Fs or kurarinone may be developed as a novel antitumor agent.

Objective To investigate the clinical characteristics and prognostic factors in patients with primary gastric non-Hodgkin lymphoma (PG-NHL).Methods The pathological data of 51 PG-NHL patients admitted in our hospital from 2003 to 2013 were analyzed retrospectively.Results In 51 patients with PG-NHL,there were 26 males and 25 females.The patients' age ranged from 18 to 80 years old with median age as 56 years old.The median survival time was 32 months (range from 1 to 114 months).The oneyear overall survival (OS),three-year OS and five-year OS were 90.2 ％,82.4 ％ and 80.4 ％,respectively.The surgery did not significantly improve PG-NHL patients' progress free survival and OS.Only 1 (2.0 ％) patient had gastrointestinal hemorrhage and perforation after chemotherapy.However,6 (46.2 ％) patients suffered from early satiety,gastric emptying disorder,alkaline reflux gastritis and dumping syndrome in surgery group.Conclusions Surgery did not improve the survival of PG-NHL patients.The life quality in chemotherapygroup is better than that in surgical group.

Plasmablastic myeloma is a rare pathological classification of multiple myeloma. This condition must be differentially diag-nosed because of lack of a distinctive phenotype. Involvement of the central nervous system is a rare complication of multiple myelo-ma. The choice of treatment is important for plasmablastic myeloma. Thus, this article presents a rare case of plasmablastic myeloma with multiple cranial nerve involvement. We clarify the diagnosis through the multidisciplinary team and select the optimal therapy for the patient.
