OBJECTIVE:To investigate the occurrence of ADR induced by Shuxuening injection in Beijing area,and to pro-vide reference for rational drug use in clinic. METHODS:ADR induced by Shuxuening injection in Beijing area during 2003-2013 was classified statistically in respects of population,organs/systems involved in ADR,clinical manifestations,occurrence time, drug combination and prognosis. RESULTS:Of 1648 ADR cases,the incidence of ADR in the elderly patients was higher than young patients,and that of female patients (60.92％) was higher than that of male patients (39.14％). Multiple organs/systems were involved in Shuxuening injection-induced ADR,and top 3 were nervous system (422 cases,21.33％),skin and its appen-dants (411 cases,20.78％) and others (305 cases,15.42％). Clinical manifestations were skin rash,itching,dizziness and ner-vousness,palpitation,arrhythmia,etc. ADR mostly occurred within 5-30 min after medication. In ADR reports,there were a vari-ety of drugs combined with Shuxuening injection. Shuxuening injection combined with Alprostadil injection was most common(61 cases,accounting for 23.46％ of drug combination). Among 1648 ADR cases,there were 622 cured cases and 1039 cases im-proved,4 cases were not improved,3 cases had sequelae and 1 case died. CONCLUSIONS:Clinical application of Shuxuening in-jection should strictly follow the indications of drug package inserts;differentiation of symptoms and signs is based on specific dos-age,solvent,route of administration,etc. It is necessary to strengthen the prescription check,and strengthen the observation after medication especially for the elderly and other special groups so as to reduce and avoid ADR.

Objective To estimate prenatal diagnoses strategy with abnormal results of non-invasive prenatal testing (NIPT) based on a case of mosaic for trisomy 22.Methods The pregnanct woman was recruited from Department of Prenatal Diagnosis Center of Xinhua Hospital.Ultrasound scans suggested fetal nuchal translucency was 3.5 mm.Peripheral venous blood was drawn from the pregnant woman for NIPT at 12+2 weeks gestation.For further prenatal diagnosis, amniocentesis was conducted at 16+2 weeks gestation, and karyotype analysis combination with chromosome microarray analysis (CMA) was executed to analysis amniocytes.Results NIPT results suggested that chromosome 21, 18 and 13 were normal and supplementary reports suggested that chromosome 22 were slightly above the normal range.Karyotype analyzed 35 cultured cells.Each of them revealed a normal female karyotype.However, CMA results suggested that chromosome 22 gain mosaic and its copy number was 2.26.The fetus was diagnosed as high possibility of mosaic for trisomy 22.Conclusions Combined with the NIPT results, which was slightly gain mosaic of chromosome 22, a prenatal diagnosis strategy were proposed.When NIPT results suggest chromosomal abnormities, karyotype analysis combination with CMA to diagnose were recommended.

OBJECTIVE: To investigate the effect and molecular mechanism of interferon-α (INF-α) on the apoptosis of the mouse podocyte cell line MPC5 induced by hepatitis B virus X (HBx) protein. METHODS: MPC5 cells were transfected with the pEX plasmid carrying the HBx gene. RT-PCR was used to measure the mRNA expression of HBx at different time points. MPC5 cells were divided into 4 groups: control group (MPC5 cells cultured under normal conditions), INF-α group (MPC5 cells cultured with INF-α), HBx group (MPC5 cells induced by HBx), and HBx+INF-α group (MPC5 cells induced by HBx and cultured with INF-α). After 48 hours of intervention under different experimental conditions, flow cytometry was used to measure the apoptosis of MPC5 cells, and quantitative real-time PCR and Western blot were used to measure the mRNA and protein expression of slit diaphragm-related proteins (nephrin, CD2AP, and synaptopodin) and the cytoskeleton-related protein transient receptor potential cation channel 6 (TRPC6). RESULTS: MPC5 cells transfected by pEX-HBx had the highest expression of HBx mRNA at 48 hours after transfection (P<0.05). Compared with the control, INF-α and HBx+INF-α groups, the HBx group had a significant increase in the apoptosis rate of MPC5 cells (P<0.05). Compared with the control and INF-α groups, the HBx group had significant reductions in the mRNA and protein expression of nephrin, synaptopodin, and CD2AP and significant increases in the mRNA and protein expression of TRPC6 (P<0.05). Compared with the HBx group, the HBx+INF-α group had significant increases in the mRNA and protein expression of nephrin, synaptopodin, and CD2AP and significant reductions in the mRNA and protein expression of TRPC6 (P<0.05). CONCLUSIONS INF-α can inhibit the apoptosis of podocytes induced by HBx, possibly through improving the abnormal expression of slit diaphragm-related proteins (CD2AP, nephrin, and synaptopodin) and cytoskeleton-related protein (TRPC6) induced by HBx.

This study aims to investigate the effect of total flavones of Fructus Chorspondiatis (TFFC) on the mRNA and protein expression of collagen type I and III of rat cardiac fibroblasts (CFs) induced by angiotensin II (Ang II), and explore its anti-myocardial fibrosis molecular mechanism. Neonatal rat CFs were prepared from Sprague-Dawley rats (1-3 d after birth). The expression of collagen type I and III mRNA and protein were measured by RT-PCR and Western blotting, respectively. The study showed that stimulation of neonatal rat CFs with 100 nmol.L-1 of Ang II for 72 h resulted in a significant increase of the expression of collagen type I and III mRNA and protein. The changes on the expression level were blocked by TFFC. The results demonstrated that TFFC can inhibit myocardial fibrosis induced by Ang II in rats, which is probably associated with the collagen type I and III mRNA and protein levels up-regulated by Ang II, and TFFC was shown to decrease the expression levels of collagen type I and III mRNA and protein.

Hyperlipidemia (HLP) is the No.1 risk factor for patients with atherosclerosis (AS) and is directly related to the occurrence of coronary artery disease (CAD) and cerebrovascular disease. Therefore, prevention and treatment of AS is of great importance and of practical significance in controlling the incidence and mortality of CAD. With its peculiar syndrome-dependent therapy, traditional Chinese medicine (TCM) has accumulated abundant practical experiences in this field and good clinical effects have been achieved. Chinese herbal medicine, with its particularly unique advantages and high potentials yet to be tapped, displays its huge strength in HLP prevention and treatment. The progress of studies concerning prevention and treatment of HLP by Chinese herbal medicines, in the form of monomers or compound recipes, is reviewed in this paper.

Objective:To evaluate the value of 68Ga-labeled prostate-specific membrane antigen( 68Ga-PSMA PET/CT)in the diagnosis of prostate cancer(PCa) and determination of the strategy on neurovascular bundle(NVB)preservation and lymphadenectomy before surgery. Methods:We retrospectively analyzed the clinical data of 46 patients with newly diagnosed PCa who underwent 68Ga-PSMA PET/CT from June 2018 to October 2019. The median age was 66.50 (60.00, 69.25) years old and the median PSA was 15.97(8.58, 33.10)ng/ml. Forty-one patients were diagnosed PCa and 5 were diagnosed with benign prostatic hyperplasia or prostatitis by 68Ga-PSMA PET/CT, 6 were diagnosed with lymph nodes metastasis. Forty patients underwent mpMRI, 33 were diagnosed PCa, and 6 were diagnosed with lymph nodes metastasis. Seventeen patients underwent 11C-choline PET/CT, 12 were diagnosed PCa, and 4 were diagnosed with lymph nodes metastasis. Among the 41 patients which were diagnosed PCa by 68Ga-PSMA PET/CT, 26 were confirmed with PCa by needling biopsy, 12 did not undergo the needling biopsy and 3 had negative biopsy; 22 were in the high-risk group, and 19 were in the low- and medium-risk group. All 41 patients underwent radical prostatectomy. The strategy of NVB preservation was determined by the position of the PCa reported by 68Ga-PSMA PET/CT. If the tumor was close to the unilateral prostate capsule, the healthy part of the NVB would be preserved. And if the tumor was limited in the prostate gland, bilateral NVB would be preserved. The NVB was preserved in 16 cases(6 cases unilateral and 10 cases bilateral). In addition to routine lymph node dissection for patients in the high-risk group, lymph node dissection was also performed on patients with 68Ga-PSMA PET/CT that showed positive lymph nodes in the low- and medium-risk groups. The paired chi-square or Fisher exact test was used to compare the sensitivity and specificity of 68Ga-PSMA PET/CT, mpMRI, and 11C-choline PET/CT for lesion detection. Spearman analysis was used to examine the correlation between the SUV max, Gleason score, and the PSA value before treatment. Results:Forty-one patients undergoing radical resection were diagnosed PCa by postoperative pathology, and no cancer tissue was observed at the surgical margin; the median Gleason score was 8(7, 9); 20 cases (48.8%) had a pathological stage ≤pT 2c; 21 cases (51.2%)≥pT 3; 7 cases were N+ (11 positive lymph nodes). Seven cases (17.1%) had complications of Clavien-Dindo ≤ grade 2 within 30 days after surgery, and there was no complication above grade 3 after surgery. The median follow-up time of the 41 patients was 16(12, 20). The rate of urinary control was 46.3%, 95.1%, and 100% after 1 month, 6 months, and 12 months follow-up respectively. Among the five patients that did not undergo surgery, the PSA value of 4 decreased after antibiotic treatment, and biopsy was performed in 1 case without PSA decreasing, and no carcinoma was found. The sensitivity of 68Ga-PSMA PET/CT on the primary PCa was 100%(41/41), which was significantly better than that of 11C-choline(80%, 12/15, P=0.016)and mpMRI (83.7%, 31/37, P=0.009), while no statistical significance was observed between the specificity of 68Ga-PSMA PET/CT (5/5)and 11C-choline PET/CT(2/2, P=1.000), 68Ga-PSMA PET/CT and mpMRI(1/3, P=0.107). Of the 41 patients that were diagnosed with PCa, the sensitivity of 68Ga-PSMA PET/CT to lymph nodes metastases(71.4%, 5/7) had a significant difference with that of mpMRI(16.7, 1/6, P=0.016), but no statistical difference with 11C-choline (75%, 3/4, P=1.000). Analysis of the relationship between SUV max of 68Ga-PSMA PET/CT, Gleason score, and PSA value before treatment revealed that the SUV max of 68Ga-PSMA PET/CT in patients with Gleason score ≥8 and <8 score were 19.60(9.58, 24.38) and 8.55 (5.18, 12.88); SUV max of patients with PSA values ≥20 ng/ml and <20 ng/ml before treatment were 19.40 (13.00, 23.50) and 8.40 (5.35, 13.95), respectively, the differences were statistically significant (all P<0.05). Conclusions:68Ga-PSMA PET/CT had high sensitivity and specificity for the diagnosis of primary prostate cancer lesions, but the sensitivity for the diagnosis of lymph node metastasis was not enough to guide the preoperative decision of whether to remove the lymph node and the scope of the removal. However, the treatment strategy of whether to retain NVB could be formulated according to the tumor location displayed by 68Ga-PSMA PET/CT before surgery.

β1 -adrenergic receptor (β1 -AR ) down regulation or knockout may effectively decrease blood pressure in SHR mice.Instead , up regulation of β1-AR would show an opposite effect:increasing heart rate, arrhythmia and hypertension.The research focused on how β1 -AR influence cardiovascular system and the blood pressure in different levels of expressions.This study could help us know more about β1-AR gene and β1 -AR, their functions and the corelation between β1 -AR and blood pressure changes.

PURPOSETo compare the efficacy of percutaneous poking reduction and fixationwith open reduction and fixation in the treatment of displaced calcaneal fractures.

METHODSReports of studies using case-controlled trials (CCT) to compare the percutaneous poking reduction and fixation with the open reduction and fixation in the management of calcaneal fractures were retrieved from the Cochrane Library, PubMed Database, CNKI, Chinese Biomedical Database, Wanfang Data (from January of 2005 to August of 2015). Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical software Revman 5.0 was used for data-analysis.

RESULTSFifteen articles were included in the meta-analysis. Comparison of the efficacy of percutaneous poking reduction and fixation with open reduction and fixation in the treatment of calcaneal fractures revealed statistical significance in the incidence of complications after operation [RR = 0.32, 95% CI (0.20, 0.5), p < 0.05]. However, there were neither statistical significance in the degrees of recovery for calcaneal Bohler angle [WMD = -1.65, 95% CI (-3.43, 0.14), p > 0.05] and calcaneal Gissane angle [WMD = -3.21, 95% CI (-6.75, 0.33), p > 0.05], nor statistical significance in the rate of good foot function after operation [RR= 0.95, 95% CI (0.90, 1.00), p > 0.05].

CONCLUSIONFor the treatment of calcaneal fractures, percutaneous poking reduction and fixation is su- perior to open reduction and fixation in terms of the incidence of postoperative complications. But both techniques can obtain satisfactory clinical function.
