OBJECTIVETo assess the efficacy of tendons of minimally invasive therapy (TMIT) combined drug therapy by comparing it with treatment by drug therapy alone on patients with knee osteoarthritis (KOA).

METHODSTotally 60 KOA patients were assigned to the treatment group and the control group according to random digit table, 30 in each group. Patients in the control group took Hydrochloric Acid Glucosamine Capsule and Celecoxib Capsule. Patients in the treatment group additionally received TMIT. The treatment course for all was 4 weeks. Scores for visual analogue scale (VAS) and the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index were observed and recorded at week 1 and 4 after treatment by acupotomology mirror.

RESULTSCompared with before treatment, improvement was shown in VAS score, pain and stiffness degrees, activities and functions, and WOMAC scores at week 1 and 4 after treatment in all patients with statistical difference (P < 0.05). Besides, better effect was shown in the treatment group (P < 0.05).

CONCLUSIONSTMIT combined drug therapy could relieve KOA patients' pain, stiffness and joint activities, elevate the overall efficacy. TMIT was easily operated with less injury.

OBJECTIVE:To introduce the research and application of sentinel hospital pharmacovigilance system,and provide technical reference for hospital pharmacovigilance working in China. METHODS:A sentinel hospital pharmacovigilance system based on hospital information system was established,the architecture and functionality were introduced and its effects were ana-lyzed. RESULTS:The sentinel hospital pharmacovigilance system formed by hospital business information management platform and data center. Its main functions included drug data arrangement,the auxiliary reporting of ADR,active monitoring,pharmaco-vigilance information inquiry,monitoring and warning and statistical analysis,which successfully achieved the rapid reporting and active monitoring of hospital ADR. The system had applied in 20 sentinel hospitals,and the ADR reporting quantity was obviously increased after applying the system. Compared with 2015,ADR reporting in a sample sentinel hospital was increased 120.6％ since it used the system in early 2016. Besides,the system had improved the ADR reporting process,operation and input standard for the ADR reporter,shortened the reporting time and improved the efficiency of the reporting staff. CONCLUSIONS:The establish-ment and application of sentinel hospital pharmacovigilance system has greatly improved the hospital ADR monitoring management level,and it is of great significance to further strengthen the pharmaovigilance in China.

The in vitro transcribed (IVT) mRNA technology has progressed rapidly and the application of mRNA vaccines in the COVID-19 pandemic made it become the most talked-about topic. Compared with protein drugs, IVT mRNA has a lower cost; it can be modular produced and its sequence can be modified easily, so it has a broad application prospect. However, due to its short history, mRNA drugs face the problem of lacking sufficient clinical data, and there is no quality control standard for mRNA drugs except mRNA vaccines. We overview the sequence design, delivery vectors, administration, application prospect and safety considerations of mRNA drugs. We also discussed the quality control of mRNA drugs briefly.

BACKGROUNDVasoactive drugs are often necessary for reversing hypotension in patients with severe infection. The standard for evaluating effects of vasoactive drugs should not only be based on the increase of arterial blood pressure, but also on the blood flow perfusion of internal organs. The effects of dopamine and metaraminol on the renal function of the patients with septic shock were investigated retrospectively in this study.

METHODSNinety-eight patients with septic shock were divided into three groups according to the highest infusing rate of metaraminol, with the lightest infusing rate of (0.1 - 0.5, 0.6 - 1.0, > 1.0) microgxkg(-1)xmin(-1) in group A, B and C respectively. Urine output, mean arterial blood pressure (MAP), heart rate (HR), urine output, blood urea nitrogen (BUN), creatinine (CRE), urine albumin (U-ALB), urine beta(2)-microglubulin (Ubeta(2)-MG) and Apache III scores were recorded.

RESULTSBefore antishock therapy, hypotension, tachycardia and oliguria occurred to all the 98 patients with septic shock and CRE, BUN, U-ALB, Ubeta(2)-MG and Apache III scoring were abnormal in most cases. With the antishock therapy, MAP, HR, urine output, BUN and CRE in all patients returned gradually to normal (P < 0.05 or < 0.01 compared to those before antishock therapy). U-ALB, Ubeta(2)-MG output and Apache III scoring also reverted but remained abnormal (P < 0.01 compared to those before antishock therapy). No statistically significant differences in the changes of these indices with the time existed among the three groups (P > 0.05).

CONCLUSIONDopamine and metaraminol when applied to the patients with septic shock could effectively maintain the circulatory stability and promote restoration of renal function.

OBJECTIVETo evaluate the efficacy of intraoperative magnetic resonance imaging (iMRI) and multimodal navigation in surgical resection of glioblastoma.

METHODSBetween February 2009 and July 2010, 76 glioblastoma patients underwent surgical resection guided by iMRI and multimodal navigation. The cohort consisted of 43 male and 33 female patients, with a mean age of 49 years (range: 14-79 years). Rates of gross total resection (GTR) and extent of resection (EoR) were calculated at first and final iMRI scans.Pearson χ(2) test was used to compare the rates of GTR.

RESULTSiMRI and multimodal navigation were successfully implemented in all cases. Rates of GTR were misestimated by neurosurgeons in 24 cases (31.6%), which were confirmed by first iMRI. Total tumor resection were achieved in 20 cases (26.3%) as a result of iMRI scan, increasing the rates of gross total resection from 52.6% to 78.9% (χ(2) = 11.692, P = 0.001). Extent of resection in 28 patients who underwent further tumor resection were increased from 81.5% to 98.1%, leading to the overall extent of resection improved from 92.3% to 98.4%. At 3-month follow-up, 3 cases (3.9%) developed permanent neurologic deficits. The mean clinical follow-up was 15.6 months (range 3.0-45.0 months). The 2-year overall survival rate was 19.7%. The median progression-free survival of gross total resection group was 12 months (95% CI: 10.1-13.9 months), compared with 9 months (95%CI: 7.9-10.1 months) of the subtotal resection group (χ(2) = 4.756, P = 0.029). The overall survival of gross total resection group was 16 months (95% CI: 13.7-18.3 months), compared with 12 months (95% CI: 9.7-14.3 months) of the subtotal resection group (χ(2) = 7.885, P = 0.005).

CONCLUSIONCombined with multimodal navigation, iMRI helps maximize surgical resection of glioblastoma, preserving neurological function while increasing progression-free survival and overall survival.

OBJECTIVETo investigate the role of lysine-specific demethylase 1 (LSD1) in the process of THP-1 monocyte-to-macrophage differentiation.

METHODSQuantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blotting were performed to analyze the expression of LSD1 and interleukin-6 (IL-6) in THP-1 monocytes and THP-1-derived macrophages. Chromatin immunoprecipitation (ChIP) assay was applied to detect the occupancy of LSD1 and H3K4 methylation at IL-6 promoter during THP-1 monocyte-to-macrophage differentiation. IL-6 mRNA level and H3K4 methylation at IL-6 promoter were analyzed using qRT-PCR and ChIP assay in LSD1-knockdown THP-1 cells treated with 12-O-tetradecanoylphorbol-13-acetate (TPA) for 0, 4, 8, 12, and 24 hours. Fluorescence activated flow cytometry was performed to reveal the percentage of macrophages differentiated from THP-1 monocytes.

RESULTSThe expression of LSD1 reduced during THP-1 monocyte-to-macrophage differentiation (P<0.01). LSD1 occupancy decreased and H3K4 methylation increased at IL-6 promoter during the differentiation. With knockdown of LSD1, H3K4 methylation at IL-6 promoter was found increased after TPA treatment at different times points (all P<0.05, except 24 hours). The percentage of macrophages increased significantly in the THP-1 cells with LSD1 knockdown (P<0.05).

CONCLUSIONSLSD1 is repressed during the monocyte-to-macrophage differentiation of THP-1 cells. Suppression of LSD1-mediated H3K4 demethylation may be required for THP-1 monocyte-to-macrophage differentiation.

BACKGROUND: Intestinal and lymphoid tissues constitute an important part of intestinal immunity, which plays an important regulatory role in spleen deficiency and hydronephrosis. OBJECTIVE: To observe the effect of acupuncture on T lymphocyte subsets in lymph nodes of rats with spleen deficiency, and to investigate the correlation of spleen deficiency with intestinal immunity and the mechanism of acupuncture for spleen deficiency syndrome. METHODS: Thirty-six female Sprague-Dawley rats were randomly divided into three groups: model, acupuncture and blank control groups. The rat model of spleen deficiency was established by fatigue-induced spleen injury plus abnormal diet for 31 days. Afterwards, the rats in the acupuncture group received acupuncture at Zusanli(ST 36).Urine D-xylose excretion rate was detected during modeling and treatment.Then, the mesenteric lymph nodes were removed, and the changes in T lymphocyte subsets in the mesentericlymph nodes were observed by immunohistochemistry. RESULTS AND CONCLUSION: Urine D-xylose excretion rate under spleen deficiency in the modeling and acupuncture groups was significantly lower than that in the blank control group (P < 0.05 or P < 0.01); after acupuncture, the urine D-xylose excretion rate was significantly increased compared with the modeling group (P < 0.01), but still lower than that in the blank control group (P < 0.05). The count of CD4+T lymphocytes, count of CD8+T lymphocytes and ratio of CD4+/CD8+T lymphocytes were ranked as follows: blank control group >acupuncture group>modeling group(P<0.01 or P<0.05).These results suggest that acupuncture at Zusanli can improve the urine D-xylose excretion rate, regulate the balance of T lymphocyte subsets in mesenteric lymph node of rats with spleen deficiency, thus improving the intestinal immune function, spleen deficiency systems, disorder of intestinal digestive function, intestinal digestion and absorption, as well as anorexia, loose stool, diarrhea and other symptoms of the digestive system.

Purpose: To investigate the relationship between prostatic urethral angle (PUA) and the development of surgical capsule calculi (SCC) within the prostate, and to examine the presence and impact of intravesical prostatic protrusion (IPP). Materials and Methods: A retrospective analysis was conducted on 90 patients who underwent radical prostatectomy, with preoperative assessments using both transrectal ultrasound of the prostate (TRUS) and magnetic resonance imaging. Patients were divided into groups with and without SCC and further categorized into type 1 and type 2 stones based on the location and severity of the calculi. Statistical analysis included chi-square and independent sample t-tests, with p<0.05 considered significant. Results: Of the patients, 82.2% were diagnosed with SCC. No significant difference in PUA was found between patients with and without SCC. However, a notable disparity in IPP presence was observed, suggesting an inverse correlation with SCC development.Additionally, no significant differences were identified when comparing the two types of SCC based on PUA and IPP measurements. Conclusions The presence of IPP exhibited an inverse relationship with SCC, suggesting diminished urine flow pressure over the prostatic urethra may reduce the likelihood of SCC formation. However, no direct association between PUA and the presence or severity of SCC was identified. These findings highlight the complexity of factors contributing to prostatic calculi development and the potential role of IPP in this context.
