Osteosarcopenia is a geriatric syndrome referring to the co-existence of osteoporosis and sarcopenia.Its pathogenesis involves factors such as genetics, mechanics of the musculoskeletal system, endocrine regulatory mechanisms and molecular signaling pathways.In clinical practice, aside from comprehensive assessment of risk factors, screening of bone density, muscle strength, muscle mass and the overall body function must also be undertaken.Intervention measures primarily include therapeutic exercise, nutritional support and drugs.

Objective To compare the clinical efficacy of peritoneolaparoscopic single position nephreteral total length resection(PSPNTLR)and posterior laparoscopic subabdominal incision technique(PLSIT)in the treatment of upper urothelial carcinoma(UTUC).Methods A total of 82 UTUC patients treated in our hospital during Jan.2018 and Feb.2021 were divided into the observation group(n=41,treated with PSPNTLR)and control group(n=41,treated with PLSIT)according to the random number table method.Perioperative indicators,pain degree,inflammatory factors,bladder recurrence and distant metastasis were compared between the two groups.Results The operation time[(122.15±15.14)min vs.(160.88±17.26)min],hospitalization time[(10.07±2.14)d vs.(12.22±3.13)d]and postoperative exhaust time[(1.46±0.57)d vs.(3.10±0.88)d]were significantly shorter,the intraoperative blood loss[(42.85±4.88)mL vs.(78.22±8.17)mL]and drainage volume[(53.61±9.74)mL vs.(81.56±11.06)mL]were significantly less in the observation group than in the control group(P＜0.05).The visual analogue score(VAS)of the observation group at 6,12 and 24 h after operation was significantly lower than that of the control group(P＜0.05).The levels of interleukin-6(IL-6)and C-reactive protein(CRP)were increased in both groups one day after surgery,but the indexes were increased more significantly in the control group(P＜0.05).During the 2-year follow-up after surgery,there were no statistical difference in bladder recurrence(12.20％vs.14.63％)and distant metastasis(9.76％vs.4.88％)between the two groups(P＞0.05).Conclusion Both PSPNTLR and PLSIT have good therapeutic safety,but PSPNTLR is more effective in improving perioperative indicators,reducing postoperative pain,and inhibiting inflammatory factors.

Objective:To explore the diagnostic value of serum C-C chemokine ligand 5 (CCL5) in assessing the degree of liver fibrosis in patients with metabolic-associated fatty liver disease (MAFLD).Methods:71 MAFLD patients who visited the Department of Integrated Traditional and Western Medical Hepatology, Third Hospital of Hebei Medical University, and underwent liver biopsy histopathology examinations between October 2021 and June 2023 were selected for diagnostic testing. Simultaneously, 71 healthy subjects who underwent physical examinations at the physical examination center of the hospital were selected as the control group. Serum CCL5 levels were detected using an enzyme-linked immunosorbent assay (ELISA). Routine blood tests, liver and kidney function tests, and other tests were conducted to analyze the expression level of CCL5 and its correlation with the above indicators. The aspartate aminotransferase/platelet ratio index (APRI) and fibrosis 4 index (FIB-4) were calculated. SPSS 26.0 software was used for statistical analysis. The area under the receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficacy of CCL5 for the degree of liver fibrosis in MAFLD. The combined diagnostic efficacy of APRI and FIB-4 was further analyzed for the degree of liver fibrosis in MAFLD.Results:The expression level of serum CCL5 gradually increased with the increase in liver fibrosis stage in patients with MAFLD, and the difference was statistically significant ( P<0.05). The AUC value of serum CCL5 for diagnosing significant liver fibrosis in MAFLD patients was 0.775, with a sensitivity of 65.7%, a specificity of 80.6%, and an optimal cutoff value of 49.845 ng/ml. The CCL5 and FIB-4 combination had the highest diagnostic value for significant liver fibrosis in patients with MAFLD, with an AUC of 0.802, a sensitivity of 91.4%, and a specificity of 61.1%. Conclusion:CCL5 has a high diagnostic value for significant liver fibrosis in MAFLD patients. Therefore, it is expected to become a non-invasive diagnostic marker for assessing the degree of liver fibrosis in MAFLD patients.

Objective:To investigate the therapeutic impact of combining vitamin D supplementation with dietary adjustments on elderly male patients with diabetes and osteosarcopenia.Methods:From January 2021 to May 2023, a total of 108 male patients diagnosed with diabetes and osteosarcopenia were admitted to Beijing hospital for research purposes.The patients were randomly assigned to either a control group( n=54)or a trial group( n=54).The control group received conventional dietary adjustments, while the trial group received vitamin D supplementation in addition to dietary adjustments.Various parameters including 25-(OH)-VitD 3 levels, blood glucose levels, appendicular skeletal muscle mass index(ASMI), bone mineral density, and bone metabolism indexes were measured before and after the treatment in both groups. Results:Compared to the pre-treatment period, the levels of 25-(OH)-VitD 3, grip strength, 6 m step speed, and ASMI increased in both groups, while fasting blood glucose and 2 h postprandial blood glucose decreased significantly(all P<0.05).Additionally, the experimental group showed higher levels of 25-(OH)-VitD 3, grip strength, 6 m step speed, and ASMI compared to the control group post-treatment, with lower levels of fasting blood glucose and 2 h postprandial blood glucose(all P<0.05).Compared with the pre-treatment period (bone density values in the lumbar spine: 0.41±0.09, the hip: 0.42±0.12 in the control group; bone density values in the lumbar spine: 0.43±0.07, the hip: 0.44±0.09 in the experimental group), the bone density values of the lumbar spine and the hip were higher in both groups after treatment(bone density values in the lumbar spine: 0.76±0.12, the hip: 0.78±0.12 in the control group; bone density values in the lumbar spine: 0.95±0.22, the hip: 0.97±0.28 in the experimental group). The bone density values of the lumbar spine and the hip in the experimental group were higher than those of the control group after treatment(all P<0.05).Furthermore, serum concentrations of parathyroid hormone(PTH)and osteoclast differentiation factor(RANKL)were significantly lower, while serum osteocalcin(OCN)was significantly higher in both groups post-treatment(all P<0.05).In the experimental group, serum PTH and RANKL concentrations were significantly lower and serum OCN was significantly higher compared to the control group post-treatment(all P<0.05). Conclusions:The results show that incorporating vitamin D into dietary changes can effectively regulate blood glucose levels, decrease bone loss, enhance bone density, and improve muscle quality in this patient population.

Objective:To investigate the neurobiochemical metabolites of caudate nucleus and thalamus in patients with obsessive-compulsive disorder and their relationship with obsessive-compulsive symptoms.Methods:From April 2019 to January 2022 in Beijing Anding Hospital, totally 25 untreated patients with obsessive-compulsive disorder were recruited, and 20 healthy controls matched with gender, age and educational background were recruited for the study.The maps of neurobiochemical metabolites of patients and normal controls were collected by hydrogen proton magnetic resonance spectroscopy.With bilateral caudate nucleus and thalamus as brain regions of interest.The relative concentrations of N-acetylaspartic acid (NAA), glutamic acid (Glu) and γ-aminobutyric acid (GABA) were fitted by LCModel software.At the same time, the clinical symptoms of patients were evaluated with Yale-Brown obsessive-compulsive scale (Y-BOCS) and Hamilton anxiety scale (HAMA). SPSS 20.0 software was used for statistical analysis.Independent double sample t-test was used to compare the differences of different nerve biochemical metabolite concentrations between patients with obsessive-compulsive disorders and healthy controls.Pearson correlation analysis was used to explore the correlation between biochemical metabolite concentrations and clinical symptoms. Results:The Glu concentration in the left thalamus of patients with obsessive-compulsive disorder (3.97±0.41) was higher than that of the control group (3.66±0.55)( t=-2.11, P<0.05), while the NAA concentration was (4.87±0.47)lower than that of the control group (5.15±0.44)( t=2.05, P<0.05). The GABA concentrations in the right caudate nucleus (0.50±0.18) and thalamus (0.80±0.19) were lower than those in the control group ((0.63±0.23), (0.96±0.24))( t=2.08, 2.36, both P<0.05). Pearson correlation analysis showed that the Glu concentration in the left caudate nucleus of patients with obsessive-compulsive disorder was positively correlated with the total score of Y-BOCS( r=0.46, P<0.05). Spearman correlation analysis showed that Glu concentration in the right caudate nucleus was positively correlated with the total score of HAMA in patients with obsessive-compulsive disorder ( r=0.46, P<0.05). Conclusion:NAA, Glu and GABA metabolism in caudate nucleus and thalamus are abnormal in patients with obsessive-compulsive disorder, and Glu concentration is positively correlated with the severity of obsessive-compulsive and anxiety symptoms.

Objective:To summarize the correlation between anterior pituitary function and tumor size in patients with different hormone-secreting pituitary adenomas.Methods:This was a retrospective case series study. The clinical data of 1 946 patients with pituitary adenoma hospitalized in the First Medical Center of Chinese PLA General Hospital from January 1, 2005, to December 31, 2020, were collected. The correlation between tumor size and anterior pituitary hormone levels was analyzed using Spearman rank correlation analysis in different types of pituitary adenomas.Results:The median age of the 1 946 patients was 45.1 years, of which 857 (44.0%) were men. The maximum tumor diameter of the patients [ M ( Q1, Q3)] was 22 (14, 30) mm. Tumor size in nonfunctioning adenomas ( n=1 191) was negatively correlated with adrenocorticotropic hormone (ACTH) ( r=-0.11, P<0.001), growth hormone ( r=-0.13, P<0.001), and luteinizing hormone (men: r=-0.26, P<0.001, women: r=-0.31, all P<0.001). The tumor size of somatotropic adenomas ( n=297) was positively correlated with growth hormone ( r=0.46, P<0.001), but negatively correlated with male testosterone ( r=-0.41, P<0.001). The tumor size of ACTH-secreting pituitary adenomas ( n=155) was positively correlated with the ACTH level at 8∶00 AM ( r=0.25, P<0.001); however, no correlation was found with cortisol at 8∶00 AM ( P>0.05). The tumor size of prolactinomas ( n=303) was positively correlated with the prolactin level (men: r=0.34, P=0.001; women: r=0.13, P=0.070). Conclusions:The correlation between the function of the anterior pituitary and size of the tumor depends on the cellular origin of the pituitary adenoma and specific type of hormone secretion. In somatotroph adenomas, ACTH-secreting pituitary adenomas, and prolactinomas, there is a positive correlation between tumor size and level of hormones secreted by the corresponding tumors. In patients with nonfunctioning adenomas, the tumor size was negatively correlated with the hormone levels of the pituitary-adrenal and pituitary-growth hormone axes.

OBJECTIVE To monitor the occurrence of tenofovir disoproxil fumarate （TDF）-induced kidney injury and investigate the risk factors， and provide reference for rational use of TDF in clinic. METHODS The information of inpatients with hepatitis B was collected by China Hospital Pharmacovigilance System （CHPS） from the Second People’s Hospital of Lanzhou during Jan. 1st， 2019 to Dec. 31st 2021. The search criteria were set according to kidney injury criteria， and suspected TDF- induced kidney injury cases were actively monitored； then the clinical pharmacist confirmed the positive patients with TDF-induced kidney injury one by one and calculated the incidence of TDF-induced renal injury； the risk factors for TDF-induced kidney injury in real world were explored by collecting and analyzing the correlation of basic data of patients， main indexes of liver and kidney function， complications and combined use of drugs with TDF-induced renal indexes. RESULTS Totally 1 226 inpatients with hepatitis B using TDF were included. Through active monitoring of CHPS， 160 suspected patients with TDF-induced kidney injury were found， and 64 positive patients were finally confirmed manually. The incidence of TDF-induced kidney injury was 5.22%. Compared with pre-medication， the levels of serum creatinine and cystatin C， the proportion of patients with urinary protein 2+ and above were increased significantly after medication （P＜0.001）， glomerular filtration rate and blood phosphorus level were reduced significantly （P＜0.001） and other indicators had no statistical difference. Treatment time for more than 36 months， disease progresses to decompensated cirrhosis， and concomitant use of more than 10 kinds of drugs were significantly correlated with TDF- related kidney injury （P＜0.05 or P＜0.012 5）. CONCLUSIONS The active monitoring scheme of TDF-induced kidney injury established by CHPS has the characteristics of time-saving， labor-saving and high efficiency； based on real-world evidence， it is imperative to strengthen monitoring kidney function of patients when using TDF， especially when the patient has been on medication for a long time， in decompensated cirrhosis and combination of multiple drugs， and thus， we can identify earlier and avoid adverse effects in high-risk patientseffectively.

Objective: To investigate the association of GNA11 gene polymorphisms with the risk of adult-onset non-surgical hypoparathyroidism (Ns-HypoPT). Methods: Genotyping of GNA11 single nucleotide polymorphisms (SNPs) (rs28685098, rs4806907, rs11084997 and rs78003011) was carried out in 203 patients and 209 healthy participants by sequenom MassArray iPLEX System. These SNPs are located in promoter and 3′untranslated region (3′UTR) of GNA11 gene, respectively. Results: Allele and genotype frequencies of rs11084997 in patients were significantly different from those of controls (genotype GG:60.5% vs. 49.8%, GC: 35.5% vs. 41.6%, CC: 4.0% vs. 8.6%, P=0.038; G allele 78.3% vs. 70.6%, C allele 21.7% vs. 29.4%, P=0.012), and the C allele of rs11084997 carriers had a lower risk to develops Ns-HypoPT in additive and dominant genetic models [OR=0.382 (0.160-0.915), 0.647 (0.437-0.957)]. CC-Haplotype formed by the minor alleles of rs4806907 and rs11084997 was associated with a decreased risk of Ns-HypoPT in additive, dominant and recessive genetic model [OR=0.317 (0.126-0.801), 0.640 (0.430-0.952), 0.367 (0.148-0.912)]. Conclusion The minor allele C of rs11084997 in GNA11 gene promoter was associated with decreased risk of Ns-HypoPT in Chinese population.

Objective: To explore the feasibility and advantages of totally laparoscopic radical cystectomy plus ρshape orthotopic ileal neobladder, and to summarize the experiences. Methods: The clinical data of 11 patients with bladder cancer admitted to the second hospital of Hebei medical university from October 2018 to May 2019 were retrospectively analyzed. All patients were male, aged 33 to 77 years, with an average of 64.4 years. Body mass index ranged from 18.0 to 31.8 kg/m^2, with an average of 23.2 kg/m². One case underwent partial cystectomy and 10 cases underwent transurethral resection of bladder tumor, with 10 cases of invasive urothelial carcinoma and 1 case of adenocarcinoma. No case underwent neoadjuvant therapy, and all cases were clinically staged as cT_2a-3bN_0-2M₀. Totally laparoscopic radical cystectomy and ρ shape orthotopic ileal neobladder intraperitonealy were performed. The specific procedures were described as follows. After bladder resection, the ileal segment of 55 cm in length was intercepted at 25 cm from ileocecal valve, with the proximal part retaining 15 cm lumen as the input loop, and the distal part of 40 cm ileum being folded in 1∶1 ratio. The folded intestinal segment was made into a allantoic sac by using a linear incision closure device, forming a "ρ" shape with the input loop, bilateral ureters and the input loop. Anastomosis of wall, distal end of allantoic and urethra was performed.Record the perioperative data such as operation time, estimated bleeding, postoperative recovery, complications, and follow-up results. Result: All of the 11 cases underwent successfully operation, and no cases were transferred to open surgery. The operation time ranged from 320 to 440 minutes, with an average of 357.1 minutes. The estimated amount of bleeding ranged from 100 to 300 ml, with an average of 207.1 ml. The total time of intestinal tract procedure was 80-100 minutes, with an average of 89.3 minutes, and the time of allantoic preparation was 14-19 minutes, with an average of 16.1 minutes. The pain score was 2-5 points at 4 hours after operation, with an average of 3.8 points, and 1-4 points at 24 hours after operation, with an average of 2.3 points. Postoperative exhaust time ranged from 2.5 to 3.5 days, with an average of 3.0 days.Catheter removed 21 days after operation, with 9 cases of urinary incontinence, including mild in 6 cases, moderate in 2 cases and severe in 1 case, with daytime pad of 0-3 and nighttime pad of 1-3.which improved gradually following pelvic exercise for 4-18 weeks. Postoperative hospital stay ranged from 7 to 13 days, with an average of 10.4 days. The drainage removal time was 4-11 days, with an average of 6.7 days. Postoperative pathology revealed 7 cases of high-grade invasive urothelial carcinoma, 3 case of low-grade invasive urothelial carcinoma and 1 case of adenocarcinoma. The tumors invade the prostate in adenocarcinoma patient, with left (3/13) and right (1/9) positive lymph nodes. One case of high-grade invasive urothelial carcinoma had both left (2/11) and right (1/9) positive lymph nodes, and the other cases were negative. The margin were negative in all patients. Pathological staging was pT_2a-4aN_0-2M₀. Postoperative adjuvant chemotherapy with gemcitabine+ cisplatin regimen were performed in 9 patients.The follow-up period ranged from 3 to 29 weeks, with an average of 17.4 weeks, the patients with adenocarcinoma died of multiple organ failure at the 13th week after operation, and the other cases have no recurrence or metastasis. Dual J-tube was removed in 9 cases in the last follow-up, and the new bladder volume was estimated 300-350 ml, with residual urine of 0-43 ml and 19 ml of average. There is no stone formation in the new bladder.No hydronephrosis or ureteral dilatation aggravated. Conclusions Totally laparoscopic radical cystectomy plus ρ shape orthotopic ileal neobladder simplify the procedure of making allantoic storage and shorten the procedure time. The patients suffered less pain and recovered quickly after operation.It is a safe and feasible surgical procedure based on this study.
