Objective:To compare the clinical characteristics in primary hyper(-) parathyroid hormone (PHPT) of the different patholog-ic types. Methods:Clinical data of 140 patients with PHPT proved by operation and pathology during January 2010 to June 2016 were retrospectively analyzed. Results:A total of 140 PHPT patients, including 13 (9.29%) cases of parathyroid carcinoma (PC), 27 (19.29%) cases of parathyroid hyperplasia (PH), and 100 (71.43%) cases of parathyroid adenoma (PA). The duration of the PC group was longer than the PH group and the duration of the parathyroid adenoma (PH) group was longer than the PA group (P<0.05). The percentage of young patients with PC was higher than in the other two groups (P=0.003). The diameters of the PC group were larger than those of the other two groups, and those of the PA group were larger than those of the PH groups (P<0.05). Blood calcium, parathyroid hor-mone (PTH), AKP, fasting blood glucose (FBG), alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamete transpepti-dase (GGT), blood urine nitrogen (BUN), creatine (CRE), urinary calcium, and phosphorus of the PC group were higher than in the oth-er two groups (P<0.05). The blood calcium, PTH, alkaline phosphatase (AKP), urinary calcium of the PH group were lower than those in PA group (P<0.05). The proportion of ostalgia was 46.15%(6/13), 44.44%(12/27), and 49.00%(49/100). No statistical difference was observed (P>0.05). The postoperative calcium level of PC group was lowest (P<0.001), and the highest was of PTH (P<0.001). The pro-portions of clinical manifestation of the urinary system, digestive system, and nervous system in the PC group were 76.92%(10/13), 76.92%(10/13), and 15.38%(2/13), respectively, and these values were the highest in the three groups (P<0.05). The proportion of the clinical manifestation of the urinary system of the PH group was higher than that of the PA group. The fracture rate (30.77%, 4/13) and constipation rate (38.46%, 5/13) of the PC group were the highest among the three groups (P<0.05). Conclusion:The duration of patients with PC was the longest among the three groups. The percentage of young patients with PC was the highest. The abnormal parathyroid glands in the PC group were the heaviest. The PC group exhibited the lowest postoperative calcium level and the highest PTH level. The biochemistry and clinical manifestations of PC were obvious.

Objective To evaluate the clinical features and efficiency of surgical treatment in elderly patients with parathyroid tumor.Methods Clinical data of 12 cases (aged 60-83 years) was retrospectively analyzed.Their main complaints varies individually,including bone and muscle trouble in 9 patients,abdominal problem in 7 ones,and kidney stone in 6 ones.PTH level ranged from 78 to 2850 μg/L,and calcium level 2.6-4.5 mmol/L.Parathyroidectomy was carried out in 8 patients,while extended excision of suspected tissues in 6 ones.Intraoperative PTH determination was routinely performed.Results A drop by at least 50％ in PTH level was achieved in all cases after 10 minutes of tumor-bearing tissues excision.A much improvement of main complaints was shown in all cases about 1 week postoperatively.During the follow-up period from 18 to 48 months,both PTH and calcium levels were still in normal range in 9 patients,relapse was noticed in two cases 1 or 2 years after operation respectively.One patient died even after successful excision of parathyroid tumor.Conclusions PTH and calcium level determination is advised in elderly patients with suspected parathyroid tumor,and surgical treatment is generally safe and effective.

To study the effect of Fuzheng Huayu recipe (FZHY) on five types of isozymes of cytochrome P450 (CYP450) of normal and liver fibrosis rats by using the cocktail probe method. Dimethylnitrosamine ( DMN) was injected to induce the liver fibrosis model. After the tail vein injection with Cocktail probe solutions prepared with five CYP450s probe substrates (phenacetin-CYP1A2, omeprazole-CYP2C9, tolbutamide-CYP2C19, dextromethorphan-CYP2D6, midazolam-CYP3A4), the plasma concentrations of the five probe substrates were determined by LC-MS/MS, and the pharmacokinetic parameters were calculated by PK solutions 2. After the oral administration with FZHY, normal rats given phenacetin, omeprazole, tolbutamide and dextromethorphan showed increase in AUC(0-t) and decrease in CL to varying degrees, indicating that FZHY obviously inhibited the activities of CYP1A2, CYP2C9, CYP2C19 and CYP2D6 in normal rats, but with no obvious effect on the activity of CYP3A4. After the oral administration with FZHY, liver fibrosis rats treated with CYP2C9 showed the significant increase in AUC(0-t) and significant decrease in Vd, hut with no obvious changes in the pharmacokinetic parameters of other four types of prove substances, suggesting that FZHY could significantly inhibit the activity of CYP2C9 in rats but had no effect on the activities of CYP1A2, CYP2C19, CYP2D6 and CYP3A4. The changes in the activity of CYP450 isozymes in liver fibrosis rats may be the reason for FZHY's different effects on CYP450 isozymes in normal and liver fibrosis rats.

This study aimed to understand the dynamic distribution of infectious bronchitis virus (IBV) Jin-13 strain in SPF chickens. Ninety-day-old SPF chickens were inoculated with Jin-13, a virulent strain, and dissected at day 1, 4, 7, 10, 14, 21, 28 or 35 post-inoculation (dpi). Samples of heart, liver, spleen, lung, trachea, kidney and duodenum were collected and the N gene was detected by Sybr Green I real-time quantitative RT-PCR assays. The established method had a good linear correlation from 7.77 x 10(8) to 10(0) copies/microL. SPF chickens developed typical clinical signs of IBV at the 4th dpi, and the IBV viral concentration of tissues and organs gradually increased with a peak of up to 7.13 x 10(4) copies/microL. The viral concentration of most organs decreased by the 10th dpi, but those of the kidney, trachea and lung remained positive for IBV at 28 dpi and the heart was still positive for IBV at > 35 dpi. The results of this study, showed that the Jin-13 strain can cause prolonged virus excertion in chickens with severe renal damage.

In early 2011, the serious outbreak of porcine pseudorabies virus (PRV) infection suddenly recurred in Henan and neighboring Provinces. To investigate the etiology of massive infection with PRV, 16 800 serum samples, 905 porcine epidemic diarrhea virus (PEDV) back-feeding tissues, and 56 PR gene deleted live vaccines were colleted from January 2011 to May 2013 to detect PRV field infection using a PRV gE antibody test kit. The gE and TK genes of 11 new epidemic PRV strains were sequenced by PCR, and their molecular characteristics were analyzed. Moreover, virus titer determination, protective test against PRV, and vaccine potency testing were performed. The results showed that the detection rate of PRV field infection-positive pig farms was 68.06%, and the overall positive rate of PRV field infection in serum was 38.47%; the positive rates in breeding sows, breeding boars, reserve pigs, and commercial pigs were 40.12%, 30.88%, 54.67%, and 26.52%, respectively. The new epidemic strains were in the same evolutionary branch and belonged to the virulent strain group. Compared with the classical PRV strain, the virulence of new epidemic strains changed a little. The length of gE gene was 1 787 bp, and the length of TK gene was 963 bp. The nucleotide homologies of gE and TK genes to Chinese reference strains were 98.2%-99.8% and 98.90%-99.6%, respectively, and the amino acid homologies were 97.1%-99.8% and 97.5%-99.4%, respectively. Commercial vaccine had a 100% protective effect against the new epidemic strains. The positive rate of PRV field infection was 0% in vaccine and 40.44% in back-feeding tissues. The results confirmed that PRV field infection rates were rising sharply among pigs in Henan and neighboring Provinces after 2011. The main virulence genes of new epidemic PRV strains did not change significantly over the years. PR gene deleted live vaccines had no PRV field infection and could completely resist the attack of new strains. The virus carriage of breeding boars and reserve pigs and the serious PRV field infection in PEDV back-feeding tissues were the main causative factors for massive infection with PRV and epidemic outbreak in Henan and neighboring Provinces from 2011 to 2013.

Encephalomyocarditis virus (EMCV) is a natural epidemic zoonotic pathogen. However, no reports have been published regarding the isolation, identification and full-length genome of EMCV from a local aardvark population. In present study, an EMCV isolate HNXX13 was isolated from aardvarks named Huainan-pig in Henan Province. The systematic identification, full-length genome sequencing and molecular characteristic analysis of the isolate HNXX13 were conducted. The result showed that the isolate was spherical with a diameter of 24-30 nm, neither heat- nor acid-resistant, sensitive to trypsin, insensitive to chloroform, not protected by bivalent cationic, and the specific fluorescence was observed in the cytoplasm of BHK-21 cells infected with the isolate by using indirect fluorescence assay. The full-length genome of EMCV HNXX13 generated a 7 725bp sequence (GenBank: F771002), with 81.0%-99.9% nucleotide identity to reference strains from different animals, and 99.5% with a Chinese reference strain isolated earlier from a commercial pig herd. The phylogenetic tree based on the full-length genome and ORF sequences identified that all EMCV strains were divided into three groups G1, G2 and G3, and strain HNXX13 belonging to the G1 group with other Chinese reference strains. The result also identified that this EMCV infection could cause severe clinical signs in a local aardvark population, and enriches the molecular epidemiological data of EMCV in China. Regional differences exist in EMCV genome and transmission is limited within a certain area. However, the cross-infection and transmission of EMCV between aardvark and mice appears most likely. Mutations have occurred in some amino acids of EMCV strain HNXX13 during the transmission in local aardvark herd and these mutations might make the virus easier to infect the aardvark.
