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.

OBJECTIVETo investigate the therapeutic effect and mechanism of Qidan granule on blemycinA5-induced pulmonary fibrosis in rats.

METHODSA total of 70 SD rats were randomly divided into normal group, the model group, Qidan group and hydrocortisone group and observed for 28 days and 42 days, respectively. Rat pulmonary fibrosis was induced by intrabronchial injection of blemycinA5. Treatment started from day 14 to day 42 with Qidan granule and Hydrocortisone for 14 days (day 28 group) and for 28 days (day 42 group), respectively. The lung pathological grades were observed by hematoxylin and eosin (HE) staining and expressions of transforming growth factor beta (TGF-beta(1)) protein and tumor necrosis factor alpha (TNF-alpha) protein were tested by the immunohistochemical technique.

RESULTS(1) Lung pathobiology fibrosis were alleviated was alleviated significantly in Qidan granule group compared with those in model group and hydrocortisone group (p < 0.01). (2) In Qidan group and hydrocortisone group, the expression of TGF-beta(1) protein was 1.71 +/- 0.17 and 1, 78 +/- 0.17 in day 28 group and day 42 group, respectively. The expression of TNF-aprotein was 2.16 +/- 0.40 and 1.98 +/- 0.33 in day 28 group and day 42 group, respectively. The expression of TGF-beta(1) and TNF-alpha protein was significantly difference from those in the model group and the hydrocortisone group (p < 0.01).

CONCLUSIONSQidan granule ameliorate the pulmonary fibrosis by decreasing expressions of TGF-beta(1) and TNF-alpha proteins in lung tissue.

OBJECTIVETo examine granulocyte colony stimulating factor (G-CSF) expression in human non-small cell lung cancer (NSCLC) as well as discuss its clinicopathological significance.

METHODSSpecimens were obtained from 114 cases (53 cases with granulocyte infiltration) diagnosed pathologically as NSCLC in General Hospital of PLA. Paraffin-embedded tissues from these 114 cases of NSCLC were examined for expression of G-CSF by immunohistochemical staining. Correlation between G-CSF expression and pathological features, clinical manifestation, prognosis of patients with NSCLC was analyzed statistically. All the patients were retrospectively followed-up.

RESULTSFifty-five of the 114 NSCLC specimens expressed G-CSF, and among these 41 (41/54, 75.9%) were large cell carcinoma, nine (9/30, 30.0%) were adenocarcinoma and five (5/30, 16.7%) were squamous cell carcinoma. The expression was significantly correlated with infiltration of tumor mass by neutrophilic granulocytes, histological type, necrosis, differentiation, lymph node metastases, distant metastases, recurrence and survival period (P < 0.01). There was no significant correlation with primary tumor size (P > 0.05). Logistic multi-factor analysis revealed that necrosis, lymph nodes metastases and distant metastases RR (risk ratio) in G-CSF positive group was 5.57, 6.28 and 5.24 times higher than those of G-CSF negative group (P < 0.05). There were remarkable difference of 5-year survival rates (0 and 12.1% respectively) and survival period (42 and 62 months respectively) between positive and negative groups (P < 0.01).

CONCLUSIONSNSCLC with G-CSF excretion are mainly large cell lung cancer. The pathologic characteristics of these cases with G-CSF expression included poor differentiation, remarkable atypia, prominent necrosis and infiltration of tumor mass by neutrophils or emperipolesis. These tumors are usually more aggressive in biological behavior and have worse prognosis than those without G-CSF expression.
