Methods We divided 144 patients with bone fracture and lying in bed into the test group and the control group with 72 cases in each group from May 2006 to February 2007. Inflatable bed urinals were used in the test group and common bedpans were used in the control group. The pain alleviation, comfort degree, staining of bed sheet and skin injury were observed and evaluated in each group. Results Application of inflatable bed urinal was superior to common bedpan in the following aspects: alleviation of pain, comfort degree, staining of bed sheets and skin injury. Conclusions Adoption of inflatable bed urinal could alleviate pain, prevent the incidence of complication and reduce the workload of nurses.

Objective To investigate the effect of Pin1 novel depressor all-transretinoic acid (ATRA) in collagen-induced arthritis (CIA) mice and elucidate the underlying mechanisms.Methods CIA model mice were established,then the qualified ones were treated with ATRA and other medicines respectively.Paw thickness and volume were measured once a week in each group.The production of tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6) was detected by enzyme-linked immunosorbent assay (ELISA) in serum.Pathological changes of joints tissues were observed by hematoxylin and eosin (HE) staining.Western blot was used to detect the expression of Pin1 and nuclear factor-κB (NF-κB) between different groups.The measurement date were compared with single factor analysis of variance and independent sample t test.Results Compared with healthy control group,the paw thickness,volume and arthritis scores were significantly increased in CIA mice,compared with disease control group,joints swelling and arthritic score index were reduced in both treatment groups;TNF-α and IL-6 expression were significantly increased in CIA mice [(50.1±1.3) pg/ml,(67.6±8.3)) pg/ml] when compare with health control group [(47.1±0.6) pg/ml,(43.0± 5.2) pg/ml] (t=-9.0,P＜0.01;t=-6.9,P＜0.01),and both were decreased in treatment groups compare with disease control group (TNF-α,F=35.5,P＜0.05;IL-6,F=17.15,P＜0.01);HE staining study demonstrated that ATRA and Dexamethasone could significantly suppressthe pathological changes of joints tissues;Western blot assay demonstrated that the higher arthritis scores was,the more synovial pin1 expressed in mice,moreover ATRA and Dexamethasone decreased Pin1 and NF-κB expression in CIA mice synovial.Conclusion ATRA can successfully decrease inflammation scores and joints pathology damage in CIA mice via weaken the synovial Pin1 expression.

Objective:To explore the feasibility and safety of the clinical application of the diagnosis and treatment mode combining rapid frozen pathological examination of prostate biopsy tissue with radical prostatectomy.Methods:Suspected prostate cancer patients with PSA>10 ng/ml and PI-RADS score ≥4 in, Northern Jiangsu People's Hospital from April to September 2021 were collected. The included patients underwent mpMRI/TRUS image fusion-guided transperineal prostate targeted biopsy with 16G biopsy needle, 2-3 needles for biopsy, and rapid frozen pathological examination. Robot-assisted laparoscopic radical prostatectomy (RALP) was performed immediately for patients with prostate cancer with rapid freezing pathology. For undiagnosed prostate cancer, 18G biopsy needle for prostate targeted + systematic biopsy were used, 18-22 needles for systematic biopsy, and routine pathological examination. The baseline data, frozen pathological results, perioperative conditions, pathological results and follow-up data of all patients were collected.Results:Eleven patients were included in the study, the mean age of the patients was 69.9(66-73) years, the mean BMI was 22.8(19-26) kg/m 2, the mean PSA was 23.2(14.25-32.00), the mean prostate volume was 45(32-52) ml, mean PSAD 0.54(0.33-0.75). PI-RADS score was 4 in 3 cases and 5 in 8 cases; digital rectal examination was positive in 5 cases. All 11 cases underwent rapid freezing and the pathological results showed that: 9 cases were prostate adenocarcinoma, and RALP was performed immediately. The operation time was 111.5(96-126) min, the intraoperative blood loss was 78.9(55-105) ml, and the postoperative extubation time was 4.3(3.5-5.0) days, postoperative hospital stay 5.8(5.0-6.5) days. Postoperative pathology showed that Gleason score 3+ 4=7 in 1 case, 4+ 3=7 in 3 cases, 8 points in 4 cases, and 10 points in 1 case; 3 cases had positive resection margins, and 1 case had seminal vesicle invasion, the average number of dissected lymph nodes was 10.9 (8.5-14.0), and there was no tumor metastasis. Pathological T staging included 2 cases of T 2b stage, 5 cases of T 2c stage, 1 case of T 3a stage, and 1 case of T 3b stage. Two patients were undiagnosed by rapid freezing pathology, of which one was prostate adenocarcinoma with a Gleason score of 4+ 3=7, and then received RALP; the other one was prostate inflammation. 11 patients were followed up; the postoperative follow-up time was 3-7 months, with an average of 5.2 months. Among the 10 patients who underwent RALP, 8 patients recovered urinary continence 2 weeks after surgery, and all recovered within 2 months after surgery. Three patients with positive surgical margins were given regular androgen deprivation therapy in the second week after surgery. PSA did not drop below 0.1 ng/ml in patients with positive margins and seminal vesicle invasion 3 months after surgery. No complications of Clavien grade Ⅰ or higher occurred after operation and during follow-up. Conclusions:For patients with high suspicion of prostate cancer, rapid frozen pathological examination of prostate biopsy tissue is performed. RALP is performed immediately for patients with prostate cancer. The results show that this diagnosis and treatment model could be safe and feasible.

Objective:To investigate the effect of local anesthesia in patients with a PI-RADS score of 5 and ECOG score ≥2 for prostate puncture.Methods:Retrospective analysis of case data of 33 patients admitted to the Subei People's Hospital for prostate puncture from April 2020 to April 2022. Age (82.5±3.6) years. There were 18 cases with hypertensive disease, 8 cases with diabetes mellitus, and 6 cases with both diabetes mellitus and hypertensive disease. Body mass index (25.2±3.5) kg/m 2. prostate-specific antigen (PSA)(131.5±69.7) ng/ml. prostate volume (38.5±21.4) ml. all patients had a PI-RADS score of 5 on multiparametric magnetic resonance (mpMRI) and an Eastern Cooperative Oncology Group (ECOG) score ≥2. All 33 cases in this group underwent trans-perineal targeted prostate puncture using local anesthesia at the tip of the prostate. The visual analog score (VAS) and visual numeric score (VNS) were applied by the same surgeon to assess the patient's pain level and satisfaction at the time of puncture (VAS-1 and VNS-1) and 30 min after puncture (VAS-2 and VNS-2), and to record the duration of the procedure and the occurrence of postoperative complications. Results:In this group of 33 cases, the VAS-1 score was (1.9±0.3) and the VAS-2 score was (0.1±0.2); the VNS-1 score was (2.9±0.2) and the VNS-2 score was (3.9±0.1). Postoperative pathological results indicated that one of the 33 patients had a negative puncture result (pathology report indicating interstitial inflammation), while the rest of the patients had a positive puncture pathology report (puncture pathology report indicating prostate cancer), with a positive rate of 97%. One case of postoperative carnal haematuria occurred, which gradually improved after the patient was advised to drink water and take alpha-blockers. No perineal hematoma occurred, and all patients did not suffer complications such as urinary tract infection, urinary retention, azoospermia, vagal reaction, and infectious shock.Conclusion:In patients with a PI-RADS score of 5 and ECOG score ≥2, the use of single-hole local anesthesia for performing trans-perineal targeted puncture biopsy has the advantages of good paroxysmal pain and high safety.

The present study retrospectively analyzed the clinical data of 137 patients who underwent prostate in North Jiangsu People's Hospital from June 2020 to May 2021. All patients underwent peripheral prostatic nerve block anesthesia (PPNB). The observation group received 1% ropivacaine 32 ml local, and the control group received the same dose of lidocaine. There was no significant difference in general data before puncture between the two groups ( P>0.05). All 137 cases were performed by the same surgeon. The number of puncture needles in the observation group and the control group was (20.2±2.8) and (20.2±2.9), respectively, and the difference was not statistically significant ( P>0.05). The visual analogue scores (VAS-1) of pain during puncture in the observation group and the control group were (2.62±0.74) and (2.48±0.79) points, respectively. The visual numeric score (VNS-1) was (3.03±0.88) points and (3.15±0.80) points, respectively, and there was no significant difference ( P>0.05). 30 min after puncture, VAS-2 was (0.48±0.53) points and (0.30±0.47) points, VNS-2 was (3.31±0.48) points and (3.55±0.71) points, respectively.The differences were statistically significant ( P<0.05). There was no significant difference in overall complication rate between the two groups ( P=0.661).

Excavating the quantitative trait locus (QTL) associated with rice cooking quality, analyzing candidate genes, and improving cooking quality-associated traits of rice varieties by genetic breeding can effectively improve the taste of rice. In this study, we used the indica rice HZ, the japonica rice Nekken2 and 120 recombinant inbred lines (RILs) populations constructed from them as experimental materials to measure the gelatinization temperature (GT), gel consistency (GC) and amylose content (AC) of rice at the maturity stage. We combined the high-density genetic map for QTL mapping. A total of 26 QTLs associated with rice cooking quality (1 QTL associated with GT, 13 QTLs associated with GC, and 12 QTLs associated with AC) were detected, among which the highest likelihood of odd (LOD) value reached 30.24. The expression levels of candidate genes in the localization interval were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR), and it was found that the expression levels of six genes were significantly different from that in parents. It was speculated that the high expression of LOC_Os04g20270 and LOC_Os11g40100 may greatly increase the GC of rice, while the high expression of LOC_Os01g04920 and LOC_Os02g17500 and the low expression of LOC_Os03g02650 and LOC_Os05g25840 may reduce the AC. The results lay a molecular foundation for the cultivation of new high-quality rice varieties, and provide important genetic resources for revealing the molecular regulation mechanism of rice cooking quality.
