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 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.

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.

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.

OBJECTIVETo study how to perform the hearing screening on the infants in the rural area.

METHODSThree thousand nine hundreds and twenty-two infants, about 84% of them from rural, were born in the People Hospital of LaiZhou City from January to December in 2004. The infants were performed fast hearing screening by transient evoked otoacoustic emission (TEOAE) after the birth in 2-7 days. The fail cases were checked again after 4-6 weeks, and then were diagnosed if they still failed after following-up.

RESULTSThe infants (3612/3922, 92.1%) have been checked by TEOAE, and the examination was free in the poverty cases. The rate passed on the first check was 69.96% (2527/3922), but 1085 infants failed (30.4%), while 310 infants have not been checked (7.9%). In the 1085 cases that should be rechecked, there was only 633 cases (58.34%) accepted the check on time, while 452 cases (41.66%) missed. In the 163 cases with high-risk infants in 2004, 114 infants (69.96%) were checked, but 49 infants (29.04%) were not checked. Fourteen cases failed in the recheck, and 11 of them were checked by ABR. Two cases were found to be moderate and severe hearing loss in binaural respectively and 4 cases with mild hearing loss in monaural while 3 cases were normal.

CONCLUSIONSIt is necessary and viable for the infants on hearing screening in the rural area It should be set up and perfected the model for infants on hearing screening in rural area as soon as possible; it should be free for the poor infants to make sure everyone enjoy the health care.

OBJECTIVETo explore demographic characteristics, current diagnosis and treatment patterns of chronic myelogenous leukemia (CML) patients in China.

METHODSData of hospitalized CML patients in 2005 whole year and outpatient information (July 1 through September 30, 2006) from 15 hospitals throughout China were analyzed.

RESULTSA total of 1824 CML cases were analyzed, including 722 inpatients and 1102 outpatients. The male/female ratio was 1.78:1. The median age at diagnosis was 40.02 (2.45 - 83.29) years old, 90.41% of the patients were diagnosed at chronic phase. Proportion of accelerated phase or blast crisis patients increased to 21.66% during study period. 93.20% of the patients received blood routine and bone marrow morphologic examination at diagnosis and in monitoring; 70.29% were performed cytogenetic analysis and 51.54% performed molecular measurement in addition. The most common therapy for CML treatment was hydroxycarbamide. The proportion of patients treated with imatinib and interferon was 37.45% and 25.55%, respectively. Of 722 inpatients, 164 (22.72%) received hemotopoietic stem cell transplantation (HSCT). The proportions of accelerated phase and blast crisis patients treated with imatinib were 48.28% and 48.42%, respectively, being significantly higher than that of chronic phase patients (35.9%) (P < 0.05). The mean imatinib dosage administered in the three phases patients did not differ significantly. Imatinib resistance rates were 6.87% and 16.28% for outpatient and inpatient, respectively. In the outpatient group, the primary resistance to imatinib occurred comparably to the secondary resistance (68.75%), while primary resistance was predominant in inpatient group (65.71%). The intolerance rates of imatinib for outpatient and inpatient were 3.21%, 11.63%, respectively. The majority of patients treated with imatinb were not monitored in time: 63.38% patients evaluated hematologic response after 3 months of treatment, proportions of patients received cytogenetic examination after 6 months and 12 months of treatment were 41.41% and 27.35%, respectively. Mean cost for HSCT was 213 092 +/- 125 890 RMB.

CONCLUSIONSCML in China tends to afflict younger population than in Western countries. Most patients were diagnosed in the chronic phase. Due to restriction of financial support, only one third of CML patients were treated with imatinib, and the majority of the treated were not monitored in time. Clinicians should pay attention to resistance and intolerance to imatinib treatment in accelerated phase or blast crisis patients.
