OBJECTIVE: To observe the effect of acupuncture at Jiaji (EX-B2) points on upper limb motor dysfunction in patients after stroke. METHODS: A total of 62 patients with upper limb motor dysfunction after stroke were randomly assigned to an observation group (n=31, 3 cases dropped out) and a control group (n=31, 2 cases dropped out). Both groups received routine medical treatment and rehabilitation training. The control group was treated with conventional acupuncture at the affected side's Jianyu (LI15), Quchi (LI11), Shousanli (LI10), Huantiao (GB30), Yanglingquan (GB34), and Zusanli (ST36) etc. On this basis, the observation group received additional acupuncture at the affected side's Jiaji points from C₄ to T₅. Treatment was administered once daily, five times a week, for four weeks. Motor evoked potential (MEP) latency and amplitude of the abductor pollicis brevis and abductor digiti minimi, Fugl-Meyer assessment for upper extremity (FMA-UE), and Wolf motor function test (WMFT) scores were compared before and after treatment in the two groups. RESULTS: After treatment, both groups showed increased MEP amplitudes and decreased latencies of the abductor pollicis brevis and abductor digiti minimi (P<0.05), as well as increased FMA-UE and WMFT scores (P<0.05); the observation group had greater MEP amplitudes, shorter latencies, and higher FMA-UE and WMFT scores compared to the control group (P<0.05). CONCLUSION Acupuncture at Jiaji (EX-B2) points could enhance the excitability of upper limb motor neural pathways in upper limb motor dysfunction after stroke patients, thereby promoting motor function recovery of the upper limb.

[Objective] To explore the clinical application of cutaneous ureterostomy-flap embedding in radical cystectomy plus urinary diversion. [Methods] The clinical data of 10 patients with bladder cancer treated with this method in our hospital during Feb.and May 2023 were involved.Cutaneous ureterostomy-flap embedding was used in urinary diversion.The stoma-free rate and stenosis rate of stomas within 1 year postoperatively, differences in renal function indicators 1 day before operation and 1 year after operation, urinary diversion-related complications within 6 months postoperatively, including hydronephrosis, urinary tract infections, renal stones were analyzed. [Results] All surgeries were successfully completed.At 1 year postoperatively, renal function indicators showed no significant difference compared to preoperative levels (P>0.05). At 6 months postoperatively, 1 patient developed renal stones, successfully treated with surgery; 2 had urinary tract infection, recovered after antibiotic treatment; 2 had mild unilateral hydronephrosis, alleviated with conservative management.At 1 year postoperatively, the catheter-free rate was 80%(8/10), with no worsening of hydronephrosis or occurrence of ureteral obstruction, and the stent placement duration ranged from 97 to 211 days, average (151.63±42.47) days.The ureteral stent was not removed in 2 patients within 1 year, so the stoma stenosis rate was 20%(2/10). [Conclusion] The application of flap embedding in urinary diversion following radical cystectomy is a simple and safe procedure, with few postoperative complications, high success rate of stent removal, and overall favorable outcomes.

Objective To explore the efficacy and technical points of complete preservation of female reproductive organ in radical cystectomy.Methods In 2020 and 2021,two female patients with bladder cancer undergoing radical cystectomy in The First Affiliated Hospital of Naval Medical University were selected.The clinical conditions of the patients were evaluated before surgery,and the reproductive organs were completely preserved according to the patients'wishes during the operation.The patients were regularly followed up after surgery.The efficacy and prognosis of patients were evaluated.Results The operation was successful and the two patients recovered well without surgery-related complications.The follow-up time for two patients were 22 months and 36 months.During the follow-up period,no tumor recurrence was found,and the scores of sexual function and quality of life were good.One patient was successfully pregnant at 17 months after surgery,and routine prenatal examination and non-invasive fetal DNA testing showed no abnormalities.Conclusions Under the premise of strictly grasping the surgical indications,the complete preservation of female reproductive organs in radical cystectomy can improve patients'quality of life after surgery,especially protect the reproductive function of women of childbearing age.

Objective To explore the role of Adra1a in regulating the LPS-induced inflammation response in primary hepatocytes of lipopolysaccharide-binding protein knockout(Lbp-/-)mice.Methods Primary hepatocytes were extracted from WT and Lbp-/-mice using a two-step perfusion method,and an inflammation model was established using LPS induction.Expression of Adra1a in primary hepatocytes of Lbp-/-mice was suppressed by administering the inhibitor prazosin and transfection with si-Adra1a.The cells were divided into three groups under inhibitor conditions:control group A,LPS group A,and prazosin group.For siRNA transfection,cells were also divided into groups:control group B,LPS group B,si-NC group,and si-Adra1a group.WT primary hepatocytes were divided into two groups:control group(blank)and LPS group(12 h stimulation).Changes in the Adra1a response to LPS stimulation were verified by Western blot.Other method ologies,such as CCK-8,qRT-PCR,and Western blot assays,were used to confirm improvements in cell inflammation and the survival rate by prazosin and si-Adra1a.Results Significant elevation in Adra1a protein expression in Lbp-/-primary hepatocytes was observed post-LPS stimulation(P＜0.01),whereas no notable change was found in the wildtype.A remarkable increase in the cell survival rate was noted in prazosin and si-Adra1a groups(P＜0.01,P＜0.05).Furthermore,prazosin and si-Adra1a groups exhibited significantly reduced expression of proinflammatory factors TNF-αand IL-1 β(P＜O.01),p-p38,p-ERK,and p-JNK(P＜0.01),which are associated with cell damage and inflammation.Conclusions Following LPS stimulation,upregulation of Adra1a and proinflammatory cytokine expression was observed in Lbp-/-primary hepatocytes.Specific downregulation of Adra1a expression using prazosin and si-Adra1a significantly decreased LPS-induced proinflammatory cytokines in Lbp-/-primary hepatocytes.Adra1a is implicated in the regulation of the LPS-induced inflammation response in primary hepatocytes of Lbp-/-mice.

Objective:To investigate the value of the 8-channel eye surface phased array coil in improving image quality and demonstrating ocular masses on 3.0 T MR scanner.Methods:From July 2018 to January 2020, the data of orbital MRI in 692 patients with ocular masses on 6 medical centers were prospectively collected. The patients were simple randomly assigned into 8-channel eye surface phased array coil group (413 patients) or 8-channel head phased array coil group (279 patients), with the same MRI sequences. The signal to noise ratio (SNR) and contrast to noise ratio (CNR) were calculated in orbital anatomy structures and masses (eyelid mass, intraocular mass, lacrimal mass and orbital mass). The image quality scores including motion artifact, mass margin, the relationship between the mass and adjacent structures, and overall image quality were recorded. The differences of image quality between the two groups were compared by two independent sample t-test or Wilcoxon rank test. Results:The SNR and CNR were higher in eye surface coil group than those in head coil group ( P<0.05). The scores of ocular movement artifacts were higher in head coil group than those in surface coil group ( P<0.05). The scores of intraocular mass margin, the relationship between the mass and adjacent structures, and overall image quality were higher in surface coil group than those in head coil group ( P<0.001). There were no significant differences in mass margin, the relationship between the mass and adjacent structures, and overall image quality scores of eyelid, lacrimal gland, and orbital mass between the two groups ( P>0.05). Conclusion:3.0 T MR scanner combined with the 8-channel eye surface phased array coil can improve the SNR and CNR of orbital MR images, the demonstration of the intraocular mass margin and the relationship between the mass and adjacent structures.

Transposons are the most prevalent elements in human genomes, which plays a vital role in gene expression regulation and evolutionary processes. They also jeopardize genome integrity with the characteristics of jumping and insertions. A delicate balance is maintained between the benefits and deleterious aspects of transposons, mediated by the epigenetic regulatory system. Once the balance is broken, it will give rise to genomic instability, leading to neoplasia. A lot of studies have shown that the transcriptional activation, expression products and methylation of transposons are closely related with urological malignancies, holding tremendous potential as biomarkers for risk and effect prediction, noninvasive diagnosis and targeted therapies of urological malignancies. In this article, the molecular mechanisms of transposons underlying the initiation, promotion and progression of urological malignancies as well as advances in diagnosis and treatment are reviewed.

Objective:To investigate the value of periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) in improving ability of demonstrating ocular masses on 3.0 T MR scanner.Methods:This study was a multi-center prospective study involving 6 centers. From July 2018 to January 2020, totally 413 patients with ocular masses from 6 centers were prospectively enrolled, and all of them underwent T 1WI and T 2WI, PROPELLER T 1 FLAIR and T 2WI, and contrast-enhanced scans. The signal intensity of eyelid, vitreous body, lacrimal gland, intraorbital segment of optic nerve, and orbital masses of eyelid, intraocular, lacrimal gland and retrobulbar were measured by two radiologists, and the signal to noise ratio (SNR) and contrast noise ratio (CNR) were calculated. The 5-point scoring method was used to evaluate the motion artefacts, tumor edges and the relationship between the tumor and adjacent structures, and the overall score of image quality was calculated. Paired t-test or Wilcoxon signed rank test was used to compare the image quality between PROPELLER and non-PROPELLER images. Results:The SNR and CNR of PROPELLER T 2WI were higher than those of non-PROPELLER T 2WI (all P<0.001). The SNR and CNR of PROPELLER T 1 FLAIR were lower than those of non-PROPELLER T 1WI (all P<0.05). The scores of artefacts and overall image quality in PROPELLER images were higher than those in non-PROPELLER images (all P<0.001). The tumor edge and the relationship between the tumor and adjacent structures scores of eyelid, intraocular, and lacrimal gland masses in PROPELLER images were higher than those in non-PROPELLER images (all P<0.001),while compared to non-PROPELLER images, retro-global masses in PROPELLER images showed no significant differences (all P>0.05). Conclusion:PROPELLER can reduce ocular motion artefacts, effectively improve image quality and ability of demonstrating anterior (eyelid, intraocular, and lacrimal gland) masses.

Objective:To compare the application of continuous negative pressure wound therapy and conventional packing and pressure bandage in medium thick skin transplantation of difficult to fix wounds.Methods:96 patients who underwent medium thick skin transplantation of difficult to fix wounds in Suizhou Hospital Affiliated to Hubei Medical College from March 2019 to March 2020 were divided into two groups according to whether the patients were treated with continuous negative pressure wound therapy. 48 patients in the control group were treated with conventional packaging and pressure bandage, and 48 patients in the observation group were treated with continuous negative pressure wound therapy. The levels of white blood cell (WBC), C-reactive protein (CRP), skin graft survival area, skin graft survival ratio, skin hematoma ratio, length of hospital stay and incidence of complications were compared between the two groups.Results:The levels of WBC and CRP in the two groups at 7 and 14 days after treatment were significantly lower than those before treatment ( P<0.05); The levels of WBC and CRP in the observation group were significantly lower than those in the control group at 7 and 14 days after treatment ( P<0.05); The survival area and survival ratio of skin graft in the observation group were significantly higher than those in the control group ( P<0.05); The area and ratio of skin hematoma in the observation group were significantly lower than those in the control group ( P<0.05); The hospital stay in the observation group was significantly shorter than that in the control group ( t=10.472, P=0.001); The incidence of skin graft complications in the observation group was significantly lower than that in the control group (2.08% vs 12.50%) (χ 2=10.174, P=0.015). Conclusions:Continuous negative pressure wound in medium thickness skin transplantation of difficult to fix wound has obvious advantages in improving the survival area of skin graft, reducing skin graft complications and shortening hospital stay, which is worthy of clinical recommendation.
