Methods The data of 2016 Basic Service Status and Unmet Needs for People with Disabilities in Henan, China were ana-lyzed. Results A total of 1,028,598 people with physical disabilities from all 19 cities had been surveyed, accounting for 61.7% male. In terms of rehabilitation needs, there were 19,348 (1.9%) responsed surgery, 202,855 (19.7%) responsed medical treatment, 197,592 (19.2%) responsed functional training, 360,754 (35.1%) responsed assistive products, and 158,012 (15.4%) responsed nursing, there were significant differences in the number of people who needed rehabilitation among different disability levels (χ2>18.080, P<0.001). For rehabilitation ser-vice, there were 6061 (0.6%) reported surgery, 93,905 (9.1%) reported medicine, 62,967 (6.1%) reported function training, 81,437 (7.9%) reported assistive products, and 34,595 (3.4%) reported nursing, there were significant differences in the number of people who got rehabili-tation among different disability levels (χ2>15.920, P<0.01). For the people without rehabilitation services, there were 165,172 (20.3%) per-son-times lack of understanding of rehabilitation policy, 151,448 (18.6%) reported lack of rehabilitation financial support, 20,369 (2.5%) re-ported not to access rehabilitation institutions, 540,971 (66.5%) reported lack of rehabilitation professionals or services, there were signifi-cant differences in the number of people who did not get rehabilitation services among different disability levels (χ2>19.182, P<0.001). Con-clusion The unmet needs and services of rehabilitation for people with physical disabilities in rural areas in Henan were explicated. It recom-mended to train rehabilitation professionals and improve the service delivery capacity, to raise awareness, increase investment in rehabilita-tion services and provide reasonable accommodation for people with disabilities.

Objective To investigate the inhibition effects of an hTERT-promoter-dependent oncolytic adenovirus Ad-VT that expresses apoptin on human prostatic carcinoma cell PC-3. Methods MTT assay was used to measure viability of PC-3 cell which was infected by recombinant adenovirus.The viability was measured at time points of 12,24,36,48,60,72,84 and 96 h after infection.AO/EB staining,DAPI staining,Annexin V assay were used to investigate the lethal effect and style of Ad-VT on PC-3 cell in vitro.The Caspases were measured by whole cell extraction of PC-3 cells 48hrs after infection. Results Ad-VT,Ad-VP3 and Ad-GT inhibited the proliferation of PC-3 cell in vitro.Ad-VT and Ad-GT were more effective than Ad-VP3 on cell growth,P ＜ 0.05.At 48,72,96 h time points,the inhibition effect of Ad-VT on PC-3 cell exhibited a dose related manner.When infection at MOI 100,the inhibition effect of Ad-VT on PC-3 cells exhibited time related manner.The AO/EB staining,DAPI staining,Annexin V assay,Annexin V assays and Caspase assays showed that Ad-VT inhibited the proliferation of PC-3 cells by inducing apoptosis of prostate cancer cells,Loss of cytoplasmic membrane integrity. Conclusions The hTERT-promoterdependent oncolytic adenovirus Ad-VT could effectively suppress prostate cancer cells PC-3 growth.

Objective To evaluate the efficacy and safety of management of kidney calculi in non-uronephrosis by percutaneous nephrolithotripsy (PCNL) under ultrasound guidance. Methods From July 2005 to June 2008, 97 cases of kidney calculi in non-uronephrosis were performed by percutaneous nephrolithotripsy. A tube was first inserted into the pelvis through cystoscope, and saline was instilled to dilate collecting system. Antegrade percutaneous access was obtained under ultrasound guidance. A combination of pneumatic and ultrasonic lithotrite was used to disintegrate and remove stone under direct vision. Clinical data including operation time, complications and stone free rate were analyzed retrospectively. Results The perutaneous renal access was successfully established under ultrasound guidance in all patients, immediate phase Ⅰ lithotripsy was performed in 95 cases and delayed phase Ⅱ lithotripsy in 2 cases. Operation time was 70-180 min, average time was (96±23 ) min. The average blood loss was 60 ml (20-500 ml), 4 cases had transfusion during the PCNL and average 400 ml. Minor pyrexia ( < 39℃) was seen in 24 cases,whereas serious pyrexia was noted in 3 cases. Conservatively administered with appropriate antibiotics, the fever disapeared in 27 cases within 5 days postoperatively. Severe complications did not occur during nephrolithotripsy. Stones were cleared completely in 78 out of 97 cases (80.4%)during immediate phase Ⅰ lithotripsy, residual stone fragment was found in 19 cases. Conclusion The management of kidney calculi in non-uronephrosis by PCNL appears to be efficacious and safe under ultrasound guidance.

Objective To discuss the cause and management of delayed hemorrhage after minimally invasive percutaneous nephrolithotomy (PCNL). Methods From 2004 to 2009,there were 13 cases (10 men and 3 women, mean age 47 years) developed severe bleeding following PCNL. The cause of hemorrhage and treatments were retrospectively analyzed and summarized. Results The time of hemorrhage was 5-40 d. In 7 of 13 cases, the bleeding were was controlled by complete bed rest,hemostatic,balloon compression and clamped nephrostomy tube. Six of 13 underwent selective renal arteriography after ineffective with conservative treatment. The DSA showed 4 were false aneurysm and 2 were arteriovenous fistula. All the 6 cases were treated by the super-selective arteriolar embolization. The hematuria was disappeared 1- 3 d later. The intravenous pyelogram revealed the renal function kept well during follow-up visit. Conclusions Delayed hemorrhage is one of the severe complications, which may be caused when the renal puncture passage established as forming false aneurysm and arteriovenous fistula. The renal arteriography and super-selective arteriolar embolization could be a safe and effective treatment for the severe hemorrhage after PCNL.

Objective:To compare the clinical efficacy and safety of intra-articular injection of platelet rich plasma and hyaluronic acid in the treatment of knee osteoarthritis.Methods:The relevant literatures including the randomized control study of intra-articular injection of platelet rich plasma and hyaluronic acid in the treatment of knee osteoarthritis published from January 2010 to December 2021 were searched. The bias risk of the included literatures was evaluated by Revman 5.3 software, and the data were processed and analyzed by Stata 16.0 software. The weighted mean difference ( WMD) was calculated for the difference ofefficacy indexes, and the difference was compared by t-test. The odds ratio ( OR) was calculated for the difference of safety index, and the difference was compared by t-test. Results:① A total of 10 literatures were included, all of which were in English. ② A total of 921 patients were included in the study, of which 479 patients were treated with intra-articular injection of platelet rich plasma and 442 patients were treated with intra-articular injection of hyaluronic acid. ③ Comparing the VAS scores of platelet rich plasma injection and hyaluronic acid injection, the visual analogue scale (VAS) scores of platelet rich plasma injection patients were significantly lower than those of hyaluronic acid injection patients after 6 and 12 months of injection treatment, and the difference was statistically significant [ WMD(95% CI)=-0.66(-1.25, -0.77), P=0.029; WMD(95% CI)= -0.90(-1.51, -0.29), P=0.004]. ④ The specific performance was that the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score of patients injected with platelet rich plasma after 6 and 12 months of injection treatment was significantly lower than that of patients injected with hyaluronic acid [ WMD(95% CI)=-0.76(-1.06, 0.45), P<0.001; WMD(95% CI)=-1.35(-2.05, -0.65), P<0.01]; After 3, 6 and 12 months of injection treatment, the WOMAC stiffness score of patients injected with platelet rich plasma was significantly lower than that of patients injected with hyaluronic acid [( WMD(95% CI)=-0.37(-0.66, -0.08), P=0.011; WMD(95% CI)=-0.30(-0.57, -0.04), P=0.023; WMD(95% CI)=-0.62(-0.92, -0.33), P<0.001]; After 3, 6 and 12 months of injection treatment, the WOMAC function score of patients injected with platelet rich plasma was significantly lower than that of patients injected with hyaluronic acid [ WMD(95% CI)=-1.90 (-2.53, -1.27), P<0.001; WMD(95% CI)=-5.77(-9.20, -2.34), P=0.001; WMD(95% CI)=-5.72(-8.62, -2.82), P<0.001]. ⑤There was no significant difference in the incidence of adverse events between the two intra-articular injection methods [ OR(95% CI)=1.28(0.68, 2.42), P=0.440]. Conclusion:Compared with intra-articular injection of hyaluronic acid, the short-term clinical efficacy of injection of platelet rich plasma is equivalent to that of injection of hyaluronic acid, but the long-term clinical efficacy is better, and the safety of the two methods is similiar.
