Objective To analyze the surgical treatment and pathological manifestations in patients with hyperparathyroidism. Methods The clinical data of 368 patients undergoing parathyroidectomy with hyperparathyroidism in Peking Union Medical College Hospital between Oct 1974 and Jan 2009 were retrospectively analyzed. Results 368 cases underwent parathyroidectomy. There were 249 women (67.7%) and 119 men (32. 3% ). Parathyroid lesions were located in normal positions in 318 cases (86. 4% ), and in ectopic positions in 50 cases (13.6%). The pathology of 264 cases (71.7%) was adenoma, 91cases (24.7%) was hyperplasia, 11 cases (3.0%) was carcinoma, and two cases was parathyroid cyst. Postoperatively 257 cases (68.0%) presented with hypocalcaemia, and 159 cases (66. 0% ) recovered within 7 days. Conclusions The main pathological diagnosis was adenoma. It is common for a ectopic parathyroid gland in which a parathyroid lesion is located.

Objective To discuss the features and surgical management of ectopic hyperparathyroidism.Methods Clinical data of 66 cases of ectopic hyperparathyroidism were retrospectively analyzed.Results There were 66 cases of ectopic hyperparathyroidism accounting for 11.5％ (66/575) of all ectopic hyperparathyroid cases admitted during the period from 1982-2010.Prevalence of mediastinal ectopic lesions was 71.2％ (47/66),among those 65.2％ (42/66) was in anterosuperior mediastinum,and 28.8％ (19/66) in the non-typical loci of the neck.Radionuclide imaging of parathyroid glands was the most sensitive (87.0％) method among all common positioning examinations.Average number of operation episode was 1.47,and all lesions were finally resected.After surgery 49 cases presented with transient hypocalcemia,and were cured by calcium administration.52 cases were followed up,with recurrent hyperparathyroidism in 1 case.Conclusions Diagnosis and treatment of ectopic hyperparathyroidism are dependent on the understanding of common locations of ectopic parathyroid glands.Preoperative correct location and surgical expertise are helpful for successful resection.

Background and purpose:Long non-coding RNA (lncRNA) could be an important player in cancer biology. Recent studies showed that lncRNA PCGEM1 might be important in the regulation of androgen recep-tor (AR) signaling pathway. We tried to observe the expressions of lncRNA PCGEM1 and AR in prostate cancer, and investigate their role and signiifcance in prostate cancer genesis and progress.Methods:The expression of lncRNA PCGEM1 was observed in prostate cancer by lfuorescencein situ hybridization (FISH) technique. Then detection of AR was performed by immunolfuorescence histochemistry methods. Their co-effective role was checked by RNA pull-down technique.Results:Compared with the AR-independent cell line such as PC3 or DU145, AR-dependent cell line such as LNCaP showed much higher expression of lncRNA PCGEM1 (P<0.01). PCGEM1 and AR could be co-localized in most of these prostate cancer samples, especially in the metastasis samples. Moreover, androgen deprivation promoted the translocation of PCGEM1 into nucleus. RNA pull-down results also proved the co-effective role of PCGEM1 and AR.Conclusion:This study showed that lncRNA PCGEM1 was highly expressed in metastatic prostate cancer. It was related to the progress and malignant behavior of the prostate cancer. Its co-localization with AR may play an important role in prostate cancer genesis and progress.

Objective To investigate the relationship between serum omega-3 polyunsaturated fatty acid (ω-3PUFA) and insulin resistance(IR) in patients with type 2 diabetes mellitus and non-alcoholic fatty liver disease (NAFLD). Methods This trial involved 51 patients of type 2 diabetes mellitus with NAFLD (G4 group), 50 patients of type 2 diabetes alone(G3 group), 45 patients of NAFLD alone (G2 group) and 42 healthy control subjects (G1 group). Serum ω-3PUFA profile was analyzed with capillary gas chromatography. Insulin resistance was assessed by homeostasis model assessment (HOMA-IR). ALT, AST, γ-glutamyltransferase(GGT) and serum lipids were measured. Results The levels of HOMA-IR were higher in G4 group than those in G3, G2 and G1 group(4. 90 ± 2. 54 vs 2. 38 ± 1.23, 2. 20 ± 1.15, 1.13± 0.42;P<0.05). The level of ALT, AST, GGT, TC, TG, LDL-C were higher in G4 group than those in G3, G2 and G1 group(P < 0. 05). The level of ω-3PUFA was signifieantly lower in G4 group than those in G3, G2 and G1 group(5.68 ±2.02 vs 7. 17 ±2. 38, 6.97±2.32, 10.08±2.76;P <0.05). ω-3PUFA cocentration was negatively correlated with HOMA-IR, TC, TG and LDL-C (r = -0.491, -0. 376, - 0. 462, - 0. 408, P < 0. 05). Conclusions Serum ω-3 PUFA is significantly decreased in patients with type 2 diabetes mellitus and NAFLD. Serum ω-3PUFA is negatively correlated with insulin resistance. ω-3PUEA plays a very important role in the development of diabetes mellitus and NAFLD.

To study the in situ intestinal absorption kinetics and compatibility influence of peimine and peiminine in rats, the absorption of peimine and peiminine in small intestine (duodenum, jejunum and ileum) and colon of rats was investigated using in situ single-pass perfusion method and the drug content was measured by HPLC-ELSD. Perfusion rate, pH, concentration of drug, gender and bile duct ligation can significantly affect the absorption of peimine and peiminine, the Ka, and Papp values in the condition of pH 6.8 and pH 7.4 had significant difference (P<0.01), as drug concentration irlcreased, the absorption parameters of peimine and peiminine decreased, Ka and Papp between low concentrations and middle concentrations was significant difference (P<0.01). Verapamil can not affect Ka and Papp of peimine and peiminine which are in the extract (P> 0.05). Bitter almonds and licorice can significantly reduce the absorption of peimine and peiminine with the usual dose (P<0.01), extracted separately and together had no significant difference on Ka and Papp (P> 0.05). Experimental results show that the absorption features of peimine and peiminine are basically the same, both of them could be absorbed at all segments of the intestine in rats and had no special absorption window, and with significant differences between male and female individuals. The absorption of peimine and peiminine complies with the active transport and facilitated diffusion in the general intestinal segments. Bitter almond and licorice can reduce the intestinal absorption rate ofpeimine and peiminine.

Objective SD rats were immuned with the transgenic tomatoes which carried fused gene of a region of PAc Strep-tococcus mutants and cholera toxin B subunit.The immunogenicity was tested to explore secure and economic edible vaccines a-gainst dental caries.Methods A total of 18 eighteen-day-old female SD rats were subdivided randomly into three groups:the exper-imental group which were fed with transgenic tomato juice containing chimaera protein PAcP/CTB;the positive control group which were treated with deactivated S.mutans;the negative control group which were not treated with transgenic tomato juice.Rats were immuned once per week for four weeks.Blood and saliva were collected at one day before the first immunity and one week after each immunization.IgG of blood serum and SIgA of saliva were detected using the enzyme-linked immunosorbent assay (indirect ELISA) testing.On day 70,rats were terminated.The maxillary and mandibular bones were subsequently taken out to count dental caries′scores.Results Post immunization,the experimental group and the positive control group had statistical significant levels of speci-ficity IgG in serum and SIgA in saliva compared to the negative control group (P <0.05).There was a significance difference be-tween the experimental group and the negative control group except in Dx levels of caries loss (P <0.05).Conclusion The targeted protein expressed on the transgenic tomatoes is immunogenic,which can effectively induce mucous membrane immune response and the systematical immunoreaction to suppress the occurrence of the dental caries.

Objective: To understand the behavioral characteristics of vaccination of human papillomavirus (HPV) vaccine based on diffusion of innovation theory, and to put forward suggestions for improving the vaccination willingness. Methods: The women who had made an appointment or received at least one dose of HPV vaccine in two community health service centers with HPV vaccination qualification in Hangzhou were recruited by convenience sampling method. A questionnaire survey was conducted according to cervical cancer risk factors, HPV vaccine knowledge and the time of vaccination. The diffusion of HPV vaccination and the characteristics of vaccinees in different stages was analyzed. Results: A total of 448 women, aged from 18 to 45 years old, with a median of 30.5 years old, were investigated. The spread of HPV vaccine were divided into five stages: April 2017 and before was the initial stage, with 8 leaders, accounting for 1.79%; October 2017 to February 2018 was the slowly rising stage, with 59 early vaccinees, accounting for 13.17%; April 2018 to April 2019 was the rising stage, with 160 most early vaccinees, accounting for 35.71%; May to August 2019 was the rapidly rising stage, with 170 most late vaccinees, accounting for 37.95%; September 2019 to the end of the survey was the standstill stage, with 51 laggards, accounting for 11.38%. All of the leaders had participated in cervical cancer screening, voluntarily vaccinated, and knew the susceptible population of cervical cancer, the targeted HPV types and the suitable population of vaccine. The median age of the first pregnancy was 27 years old. Six of them had three pregnancies. The early vaccinees and the most early vaccinees were recommended by doctors or friends to get HPV vaccine. The median age of first pregnancy was 26 and 28 years old, respectively. Their other characteristics were similar to those of the leaders. The characteristics of most late vaccinees were similar to those of the laggards. They were were mainly students who were recommended by their friends to receive HPV vaccination, did not participate in cervical cancer screening, did not know the susceptible population of cervical cancer, the targeted HPV types and the suitable population of vaccine. Conclusions People with high risk of HPV exposure, awareness of cervical cancer and screening are more likely to receive HPV vaccination at the early stage. It is necessary to strengthen the health education of HPV vaccination, and make full use of the influence of doctors and early vaccinees, which is helpful to promote the early vaccination of HPV vaccine among the right age population.
