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.

To study the clinical application of Jintian'ge capsule in treatment of vertebral compression fracture in senile osteoporosis patients. In the study, 69 senile osteoporotic vertebral compression fracture patients hospitalized in our hospital between January 2012 and June 2014 were selected and randomly divided into the control group and the treatment group. Patients in the control group were treated by percutaneous kyphoplasty (PKP), while those in the treatment group were given Jintian'ge capsule in addition to PKP. Efforts were made to visit the patients before the surgery and in three month after that, observe and compared the vertebral height, Cobb's angle, bone density, visual analogue scale (VAS) and Oswestry disability index between patients in the two groups. According to the findings, compared with before the treatment, patients in the two groups showed significant improvements in the vertebral height, Cobb's angle, bone density, VAS and Oswestry disability index three months after the surgery (P < 0.05); During the visit three months after the treatment, compared with the control group, the treatment group showed notable increases in all parameters (P < 0.05), particularly in the vertebral height, VAS and Oswestry disability index (P < 0.05). Based on the above findings, Jintian'ge capsule is applicable in adjuvant therapy after the osteoporotic vertebral compression facture PKP surgery.

Abstract: Objective A survey on the plague foci in Qiaojia County of Jinsha River Basin was conducted to understand the composition of plague host vectors and the prevalence of plague among animals, to explore the occurrence and epidemic risk of plague, and to provide scientific basis for plague monitoring and control in this area. Methods Seven villages and towns in Qiaojia County were selected as the research areas, and the cage night method and the clamp line method were used to investigate the small mammals and their surface parasitic fleas. The host animal organs, serum and surface parasitic flea's samples were collected. The plague indicator animal serum was collected simultaneously on the spot, and the collected host animal organs and flea's samples were cultured and detected for Yersinia pestis. The indirect hemagglutination test (IHA) was used to detect the fraction 1 capsular antigen (F1) antibody of the host animal and the indicator animal serum samples. Results A total of 525 small mammals belonging to 3 orders, 6 families, 12 genera and 23 species were captured. The dominant species in farming areas were Apodemus chevrieri (31.05%), Niviventer confucianus (13.90%) and Anourosorex squamipes Milne-Edwards (11.43%). The dominant species in residential areas were Rattus norvegicus (66.67%) and Rattus tanezumi (20.00%). The rat densities in agricultural and residential areas were 20.98% and 1.00%, respectively. A total of 277 external parasitic fleas belonging to 15 species, 13 genera, 5 families were collected. The dominant species were Palaeopsylla remota (22.02%), Neopsylla specialis specialis (20.58%), Frontopsylla diqingensis (18.77%) and Ctenophthalmus (Sinoctenophthalmus) quadratus (11.55%), and the rat fleas index was 0.53. No Yersinia pestis was isolated from all rodent organs and flea samples. A total of 167 serum samples from dogs and 15 serum samples from rats were collected, and plague F1 antibody was detected by IHA. IHA detection of plague F1 antibody were negative. Conclusions Qiaojia County has the distribution of the main host and main vector of plague, and the rat density is high, but the rat body flea index is low. There is no positive detection of plague host animals, vector fleas and indicator animals. It can be considered that the risk of plague occurrence and epidemic in the region is not high in the near future. It is necessary to further strengthen the monitoring and control of plague and other rodent-borne diseases in the region.

10.Effect of desmopressin on platelet aggregation and blood loss in patients undergoing valvular heart surgery.
Chinese Medical Journal 2015;128(5):644-647
BACKGROUNDBlood loss after cardiac surgery can be caused by impaired platelet (PLT) function after cardiopulmonary bypass. Desmopressin or 1-deamino-8-D-arginine vasopressin (DDAVP) is a synthetic analog of vasopressin. DDAVP can increase the level of von Willebrand factor and coagulation factor VIII, thus it may enhance PLT function and improve coagulation. In this study, we assessed the effects of DDAVP on PLT aggregation and blood loss in patients undergoing cardiac surgery.
METHODSA total of 102 patients undergoing valvular heart surgery (from October 2010 to June 2011) were divided into DDAVP group (n = 52) and control group (n = 50). A dose of DDAVP (0.3 μg/kg) was administered to the patients intravenously when they were being re-warmed. At the same time, an equal volume of saline was given to the patients in the control group. PLT aggregation rate was measured with the AggRAM four-way PLT aggregation measurement instrument. The blood loss and transfusion, hemoglobin levels, PLT counts, and urine outputs at different time were recorded and compared.
RESULTSThe postoperative blood loss in the first 6 h was significantly reduced in DDAVP group (202 ± 119 ml vs. 258 ± 143 ml, P = 0.023). The incidence of fresh frozen plasma (FFP) transfusion was decreased postoperatively in DDAVP group (3.8% vs. 12%, P = 0.015). There was no significant difference in the PLT aggregation, urine volumes, red blood cell transfusions and blood loss after 24 h between two groups.
CONCLUSIONSA single dose of DDAVP can reduce the first 6 h blood loss and FFP transfusion postoperatively in patients undergoing valvular heart surgery, but has no effect on PLT aggregation.
