Objective:To compare the diagnostic efficacy of 18F-prostate specific membrane antigen (PSMA)-1007 PET/CT, 18F-FDG PET/CT and multi-parameter MRI (mpMRI) in prostate cancer (PCa). Methods:Retrospective analysis was conducted on data from 22 patients ((72.6±6.2) years) with pathologically confirmed PCa in the Affiliated Taizhou People′s Hospital of Nanjing Medical University between April 2021 and September 2022. All patients underwent 18F-PSMA-1007 PET/CT, 18F-FDG PET/CT, and mpMRI examination within 30 d, and the imaging parameters were collected, including PSMA-SUV max, FDG-SUV max, minimum apparent diffusion coefficient (ADC min), mean apparent diffusion coefficient (ADC mean), PSMA-SUV max/ADC min, PSMA-SUV max/ADC mean, FDG-SUV max/ADC min, FDG-SUV max/ADC mean. Patients were divided into groups based on the International Society of Urological Pathology (ISUP) grading (≤3 vs >3) and serum total prostate specific antigen (TPSA; ≤20 μg/L vs >20 μg/L), and differences of imaging parameters between groups were compared (Mann-Whitney U test or independent-sample t test). ROC curves were generated to evaluate the diagnostic ability of each parameter for different levels of PCa. χ2 test and ROC curve analysis were used to compare the detection rate and diagnostic efficiency of three imaging methods for primary focus, lymph node metastasis, and bone metastasis in PCa. Results:Differences were found between ISUP≤3 ( n=6) and >3 ( n=16) groups in PSMA-SUV max/ADC min, PSMA-SUV max/ADC mean, PSMA-SUV max, and ADC min ( z values: from -2.65 to -2.36, t=3.60, P values: 0.002-0.018). But there was no significant difference found between TPSA≤20 μg/L ( n=5) and >20 μg/L ( n=17) groups in all indices ( z values: from -1.76 to -1.45, t values: -1.19 and 1.28, all P>0.05). The optimal cut-off value for PSMA-SUV max/ADC min in differentiating high-grade and low-grade PCa was determined to be 22.628×10 3. In the patient-based analysis, no statistical difference was found in the detection rate of PCa primary tumors among 18F-PSMA-1007 PET/CT, 18F-FDG PET/CT, and mpMRI ( χ2=1.91, P=0.767). However, the detection rates of lymph node and bone metastasis among three imaging methods were significantly different (72.73%(16/22), 59.09%(13/22), 36.36%(8/22) and 81.82%(18/22), 63.64%(14/22), 45.45%(10/22); χ2 values: 6.03, 6.29; P values: 0.049, 0.043). 18F-PSMA-1007 PET/CT resulted in a 36.36%(8/22) increase in N stage and the 40.91%(9/22) increase in M stage compared to mpMRI. Conclusions:PSMA-SUV max/ADC min is a valuable parameter for differentiating high-grade and low-grade PCa. 18F-PSMA-1007 PET/CT demonstrates superior detection rate of PCa lymph node and bone metastasis compared to 18F-FDG PET/CT and mpMRI, and exhibits higher diagnostic efficiency, so it can be recommended for NM staging in patients with PCa.

Systemic lupus erythematosus(SLE)is characterized by a large number of anti-autoantibodies produced by abnormally activated B cells,which form immune complexes with autoantigens to induce systemic inflammation,leading to the involvement of multiple systems and organs.Existing treatment strategies targeting B cells(such as belimumab,telitacicept,and rituximab)had limited efficacy.Recently,CD 19 targeting chimeric antigen receptor(CAR)-T cell has shown excellent efficacy in the treatment of SLE.However,autologous CAR-T cell therapy has potential risks such as cytokine release syndrome(CRS),T cell tumors,and infections,and it is expensive.CAR-natural killer(NK)cell therapy,on the other hand,is an off-the-shelf cellular therapy with high safety,no neurotoxicity or tumorigenic risk,and with low treatment costs.Currently,CAR-NK cell has achieved remarkable research results in treating hematological malignancies,and preliminary clinical studies of CAR-NK cell therapy for SLE have showed good efficacy,excellent safety,and predictable durability.This article focuses on the characteristics of the new generation of universal CAR-NK cell and the latest clinical research results for the treatment of relapsed and refractory SLE,offering insights into its promising future in the treatment of SLE and B-cell-related autoimmune diseases.

Objective·To explore the effects of hypertension and dyslipidemia on cognitive function in the elderly.Methods·A dynamic population cohort was established by using prospective cohort study methods.In 2019,a complete cohort was selected from residents aged 65 and above who voluntarily participated in a free physical examination program in a community in Shanghai,serving as the baseline cohort.In 2022,512 community-dwelling elderly aged 67 to 93 were randomly selected from the same community as the follow-up cohort for the study.The collected date included residents' health records,various physical examination measurements,and Mini-mental State Examination(MMSE)scale scores.Results·Of the 512 cases that were followed up,the valid sample size was reduced to 495 after data cleaning.According to the baseline and follow-up cognitive assessments and changes,the cases were categorized into three cognitive groups:the improvement group,the normal group,and the decline group.The prevalence of hypertension in the decline group was 43.14%higher than that in the improvement group and 24.39%higher than that in the normal group(66.67%in the decline group vs 23.53%in the improvement group,P=0.011;66.67%in the decline group vs 42.28%in the normal group,P=0.040).Total cholesterol(TC)in the improvement group was lower than that in the normal group[improvement group(4.38±1.04)mmol/L vs normal group(5.11±1.12)mmol/L,P=0.009].Additionally,TC in the decline group in 2022 was higher than that in 2019[paired difference(0.46±0.87)mmol/L,95%CI 0.08?0.84,P=0.021].LDL-Ch in the improvement group was lower than that in the normal group[improved group(2.51±0.92)mmol/L vs normal group(3.07±1.00)mmol/L,P=0.024],and their HDL-Ch in 2022 was higher than that in 2019[paired difference(0.16±0.20)mmol/L,95%CI 0.06?0.26,P=0.005].The results of multinomial Logistic regression showed:TC in the improved group was lower than that in the normal group[β=4.12,OR=61.64,95%CI 1.52?2494.07,P=0.029]and the decline group[β=5.88,OR=357.35,95%CI 4.54?28149.75,P=0.008];the TAG[β=1.85,OR=6.34,95%CI 1.05?38.43,P=0.045],LDL-Ch[β=5.61,OR=274.06,95%CI 3.65?20567.57,P=0.011],and hypertension[β=1.90,OR=6.69,95%CI 1.53?29.16,P=0.011]in the decline group were higher than those in the improvement group;the age of the decline group was greater than that of the normal group[β=0.08,OR=1.08,95%CI 1.00?1.16,P=0.041],and the education level was lower than that of the normal group[β=1.22,OR=3.39,95%CI 1.28?8.94,P=0.014].Conclusion·Low TC and LDL-Ch and high HDL-Ch are beneficial to cognitive improvement.Conversely,hypertension,high TC,high TAG,high LDL-Ch,low education level,and advanced ages are risk factors for cognitive decline.

To investigate the therapeutic effects of oral osthole on streptozotocin (STZ)-induced type 1 diabetes mellitus(T1DM) mice and explore its internal mechanism. METHODS: The diabetes model induced by STZ was established. Mice were randomly divided into control group, STZ model group, STZ+osthole group (20 mg/kg). Body weight, blood glucose, urine protein, blood urea nitrogen and creatinine were observed to detect renal function. The degree of renal tissue damage was detected by H&E staining and PAS staining, and the degree of renal fibrosis was detected by Sirius Red staining. CD68 and F4/80 immunofluorescence staining was used to observe the infiltration of macrophages in kidney tissue. The mRNA expressive levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) in renal tissue were detected by RT-qPCR. The protein expressive levels of phospho-NF-κB p65, NF-κB p65, IκBα, phospho-IκBα, phospho-p38 and p38 were detected by Western blot in renal tissue. RESULTS: Compared with the STZ model group, the levels of urinary protein, blood urea nitrogen, creatinine were significantly decreased after osthole treatment (P<0.05 or P<0.01). The renal structure disorder, mesangial matrix area, collagen fiber accumulation, and macrophage infiltration were significantly improved (P<0.05 or P<0.01). The expression of mRNA of pro-inflammatory cytokines TNF-α and IL-6 were significantly decreased (P<0.05 or P<0.001). The expression of phospho-NF-κB p65, phospho-IκBα and phospho-p38 were significantly down-regulated (P<0.05 or P<0.01), while the protein expression level of NF-κB p65, IκBα was up-regulated (P<0.05). CONCLUSION: Osthole has a protective effect on kidney injury caused by diabetes and inhibits NF-κB and p38/MAPK signaling pathway.

To effectively solve the serious impact of high oil in the kitchen wastewater on the downstream treatment process, an excellent oil-degrading strain Aeromonas allosaccarophila CY-01 was immobilized to prepare Chitosan-Aeromonas pellets (CH-CY01) by using chitosan as a carrier. Oil degradation condition and efficiency of CH-CY01 pellets were assessed. The growth of immobilized CH-CY01 was almost unaffected, and the maximum degradation rate of soybean oil was 89.7%. Especially at 0.5% NaCl concentration, oil degradation efficiency of CH-CY01 was increased by 20% compared with free cells. In the presence of a surfactant (sodium dodecylbenzene sulfonate) at 1 mg/L, the degradation efficiency of oil by CH-CY01 was increased by 40%. Moreover, using the high-oil catering wastewater as the substrate, more than 80% of the solid oil was degraded with 1% (V/V) CH-CY01 pellets treatment for 7 days, significantly higher than that of free cells. In summary, immobilized CH-CY01 significantly improved the efficiency of oil degradation.

OBJECTIVE:To provide data and reference for pharmacist legislation. METHODS:Questionnaire survey was de-signed investigate and analyze the staffing situation,education level,professional composition,age composition,professional titles composition,continuing education and wage of pharmacists who worked in medical and health institutions from 16 states (cities) in Yunnan province,and suggestions were put forward for relevant legislation. RESULTS:Totally 10 questionnaires were received from provincial medical and health institutions,and 16 from state (city) Health and Family Planning Commission,with effective recovery of 100%;data covered 1 561 medical and health institutions,involving 7 409 pharmacists. The numbers of pharmacy per-sonnel/hospital beds in tertiary hospitals,secondary hospitals and class-1 hospitals were 1∶15.49,1∶17.50,1∶20.68,numbers of pharmacy personnel/health professional and technical personnel in hospital accounted for 5.62%,6.18%,5.30%,respectively;most pharmacists in tertiary hospitals were mainly undergraduate degree(35.21%),doctor degree accounted for 0.15%,the high-est ratio of education was junior college degree in secondary hospitals(41.60%)and class-1 hospitals(57.51%);most pharmacists graduated in pharmacy in tertiary hospitals(94.14%),70.22% in secondary hospitals and only 10.50% in class-1 hospitals;phar-macy personnel mainly held the pharmacist professional titles in tertiary,secondary and class-1 hospitals (33.83%,37.89% and 63.55%),senior professional titles accounted for 5.88%,2.71% and 0.21%,respectively;only a few have learning experience and almost less than 6 months (9.17%,5.84% and 21.32%),and 80 pharmacists were certificated as clinical pharmacists in the whole province;generally,all wage was concentrated in 2 000-2 999 per month (27.72%,41.80% and 55.90%,respectively). CONCLUSIONS:Shortage of hospital pharmacists and lack of senior personnel are the main problems in Yunnan province,and wage is not high,especially in primary hospital,this situation is more obvious. The current situation of pharmacists in the hospital should be more taken into consideration during the legislative process in aspects of clearing and guaranteeing access qualifications, responsibilities,status,rights and interests,and pharmaceutical technology and service charges should be established.

Ribosomal S6 kinase is a family of serine/threonine protein kinases involved in the regulation of cell viability. There are two subfamilies of ribosomal s6 kinase, (p90rsk, p70rsk). Especially, p90rsk is known to be an important downstream kinase of p44/42 MAPK. We investigated the role of p90rsk on ethanol-induced cell proliferation of HepG2 cells. HepG2 cells were treated with 10~50 mM of ethanol with or without ERK and p90rsk inhibitors. Cell viability was measured by MTT assay. The expression of pERK1, NHE1 was measured by Western blots. The phosphorylation of p90rsk was measured by ELISA kits. The expression of Bcl-2 was measured by qRT-PCR. When the cells were treated with 10~30 mM of ethanol for 24 hour, it showed significant increase in cell viability versus control group. Besides, 10~30 mM of ethanol induced increased expression of pERK1, p-p90rsk, NHE1 and Bcl-2. Moreover treatment of p90rsk inhibitor attenuated the ethanol-induced increase in cell viability and NHE1 and Bcl-2 expression. In summary, these results suggest that p90rsk, a downstream kinase of ERK, plays a stimulatory role on ethanol-induced hepatocellular carcinoma progression by activating anti-apoptotic factor Bcl-2 and NHE1 known to regulate cell survival.

Objective To establish bladder reflex arc with sensory afferent pathway using SD rats,and evaluate its effect in the treatment of atonic bladder after spinal cord injury.Methods Twenty-four male SD rats were used in the study.For each rat,the right side was the experimental side,and the left side was the control side.In the right side,the L5 ventral root (VR) was anastomosed to S2 VR,and the distal end of S2 dorsal root (DR) was anastomosed to the proximal end of L5 peripheral process of dorsal ganglion.In the left side,no treatment was done.In order to evaluate the validity of the bladder reflex arc,general observation,neuro-electrophysiological test and wheat germ agglutinin horseradish peroxidase (WGA-HRP) method were used before and after the spinal cord destruction between L6 and S2 level at 3 months postoperatively.Results Twenty-one rats survived 3 months after the operation,and anastomotic nerves were separated successfully only in seven rats.Compound action potentials (CAPs) of plexus vesica and compound muscle action potentials (CMAPs) of bladder smooth muscle were found by electrical stimulation in distal end of the anastomotic stoma of the right S2 DR.There was no statistically significant difference in action potential before and after paraplegia.No action potential was detected in control sides after paraplegia.The curves of CAPs and CMAPs in the right side were similar to those in the control side,and the mean maximum amplitude reached respectively 71.9％ and 82.4％ of those in the left side before paraplegia.In addition,WGAHRP labeled cells were observed in L5 anterior horn and posterior horn in the experimental side after WGAHRP injection.Conclusion Reconstruction of bladder reflex arc with sensory afferent pathway can promote axonal regeneration of motor and sensory nerves,and then the regenerated axon could contact with cells in anterior and posterior horn of spinal cord through parasympathetic nerves,ultimately the capability of axoplasmic transportation could be reestablished.Therefore,this method can be used for treating atonic bladder.

Objective To study the effect of urodynamic factors on the urinary retention of the patients with cervical cancer received radical hysterectomy. Methods Seventy-two patients with cervical cancer Ininternational Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ bl to Ⅱ a hospitalized in Fujian Provincial Maternity and Child Health Hospital between June 2006 and August 2009, who were not found any abnormal representation of urodynamics before the operation, were divided into the group with urinary retention and the group without urinary retention based on whether urinary retention after the operation. All patients were detected by urodynamic examination following radical hysterectomy. Data obtained from urodynamic examination were analysed by logistic regression to evaluate the influence of urodynamic factors on the urinary retention postoperation. Results Twenty-one patients out of all were found with urinary retention after the operation , the incidence rate of urinary retention was 29%. The first sensation after operation in both groups were increased significantly than those before operation[ ( 171 ±61 )ml vs.(126 ±28)ml, (134±39)ml vs. (119 ± 17)ml,all P＜0.05], while the maximum volume[ (337 ±66) and (300 ±66)ml, respectively], the compliance[ (31 ±25) and (29 ± 18) ml/cm H2O (1 cm H2O =0. 098 kPa), respectively], the maximum flow rate[ (10 ±4) and (12 ±5) ml/s, respectively] and the pressure at the maximum flow rate [ (27 ±9) and (32 ±8) cm H2O, respectively] were decreased obviously after radical hysterectomy in both the group with urinary retention and the group without urinary retention ( all P ＜0.05), compared with the corresponding value before the operation. The urodynamic changes in urinary retention group was much more severe than those in group without urinary retention ( P ＜ 0. 05 ). The single factor analysis results showed that bladder destusor dysfunction ( OR = 8. 20, 95% CI: 2.62 - 25. 66, P ＜0. 01 ) and lack of sensation ( OR = 6. 90, 95% CI: 1.95 - 24. 43, P ＜ 0. 01 ) were relevant to the urinary retention post-operation. While there were not relationship was found between low compliance bladder( OR =1.99, 95% CI:0. 70 - 5.63, P = 0. 195 ), detrusor overactivity ( OR = 2. 51, 95% CI: 0. 73 - 8.67, P =0. 144), bladder outlet obstruction ( OR = 3.77, 95% CI: 0. 76 - 18. 57, P = 0. 104 ) or dyssynergia of urethral external sphincter( OR =2. 67, 95% CI:0. 49- 14. 45, P =0. 255 ) and urinary retention following the operation. There were an antagonistic effects ( OR = 7.60, 95% CI: 1.43 - 40. 39, P = 0. 017 ) of detrusor overactivity and bladder destrusor dysfunction on urinary retention. The multiple factors analysis results revealed that bladder destusor dysfunction( OR = 7.01, P ＜ 0. 01 ) and lack of sensation( OR = 5.45, P =0. 018)were the independent risk factors influening on the urinary retention post-operation. Conclusions There are obvious urodynamic change in cervical cancer patients following radical hysterectomy. Bladder destrusor dysfunction and lack of sensation are the independent urodynamic risk factors influencing on urinary retention following radical hysterectomy, while detrusor over activity may be a protective effect on bladder destrusor dysfunction post-operation in some degree. Urodynamic test is important for analysis and treatment of urinary retention following radical hysterectomy.
