AIM: To investigate the association between HBV infection and HLA-DPB1 gene in population of Guangzhou Chinese. METHODS: 58 unrelated patients (test positive of HbsAg,HBeAg,HbcAb) and 75 unrelated healthy control individuals were typed by sequencing based typing (SBT) method in their HLA-DPB1 gene. RESULTS: The phenotype frequencies of HLA-DPB1 alleles of patients and control have no significant difference. CONCLUSION: These results indicate that there is no association between HLA-DPB1 gene and HBV infection.

Objective The purpose of this study was to investigate the differences of cognitive impairment and neuropsychiatric behavior disturbances between Alzheimer's disease (AD) and frontotemporal dementia (FTD) patients,as well as their relationships with dementia severity.Methods A total of 38 FTD patients and 46 AD patients were recruited in this study.The Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE) were used to evaluate the degree of cognitive impairments.The Neuropsychiatric Inventory Brief Questionnaire Form (NPI) and Frontal Behavioral Inventory (FBI) were used to measure behavioral disturbances.The 21-items Hamilton Depression Rating Scale (HAMD-21) was used to evaluate the mental or emotional state of patients.Clinical dementia rating scale (CDR) was used to divide the dementia severity.Results FTD patients were younger ((70.13 ± 8.36) years vs (66.46 ± 7.04) years,t =2.124,P =0.037),earlier at age of onset ((68.58 ± 8.51) years vs (64.43 ± 6.82) years,t =2.396,P =0.019),with lower MoCA scores (12.50 (8.00,16.25) vs 17.00(10.75,21.00),Z=-2.428,P=0.015),higher NPI (15.00(7.00,25.50)vs 9.50(4.00,17.75),Z=-2.251,P=0.024),FBI (21.00(13.00,27.00)vs 16.00(10.75,23.00),Z=-2.159,P=0.031),FBI-A (13.00 (8.00,16.00)vs 9.00(6.00,12.00) Z=-2.159,P=0.041),FBI-B (9.00(7.00,14.00) vs 7.00(3.00,11.00),Z=-2.051,P=0.040) and HAMD-21 scores (7.00(2.75,14.00) vs 5.00 (3.00,8.00),Z =-2.061,P =0.039).A detail analysis of different cognitive domains showed the executive functions (Z =-2.140,P =0.032),language (Z =-3.357,P =0.001),abstraction (Z =-2.498,P =0.012) and delayed recall (Z =-4.317,P =0.000) of the MoCA scale were lower in FTD patients than that in AD patients,while AD patients had lower scores in memory (Z =-1.999,P =0.046) and orientation (Z =-2.941,P =0.003) of the MMSE scale.Within the subscale scores of the NPI,the agitation (Z =-3.255,P =0.001),disinhibition (Z =-3.093,P =0.002) and irritability (Z =-2.214,P =0.027) scores were higher in FTD patients than in AD patients.The total scores of NPI (r=0.279,P=0.010),FBI (r =0.353,P=0.001),FBI-A (r=0.386,P=0.000) and FBI-B (r =0.273,P =0.012) were positively correlated with the CDR scores,whereas MoCA scores were negatively correlated with the CDR scores (r =-0.760,P =0.000).The subscale scores on MoCA and NPI areas changed corresponding with dementia severity in both groups.Conclusions The cognitive function,behavioral and psychological symptoms between FTD and AD patients are different.FTD patients have poorer executive function,language,abstraction and delayed recall ability,whereas AD patients perform worse in memory and orientation.With the progression of the disease,FTD patients gradually emerged disorientation,while the cognitive impairment in AD patients almost affected all the areas.FTD patients are more likely to have agitation,disinhibition and irritability behavior,and AD patients are more likely to have depression in the late stage.Dynamic evaluation of the cognitive function,behavioral and psychological symptoms in clinical practice can help to distinguish FTD and AD.

Guillain-Barré syndrome (GBS) defines a kind of Immune-mediated acute inflammatory peripheral neuropathy. Miller-Fisher Syndrome (MFS) is a special variant of GBS, with mostly one-way course and rare clinical recurrence. Only a few recurrent cases have been reported in China. Here we report a case of a young male patient with double vision and progressive aggravation of limb numbness, acute onset, with symptoms of upper respiratory tract infection before onset, accompanied by pupil abnormalities and autonomic nervous dysfunction, who was was admitted to our hospital for similar symptoms 3 years ago and was improved by immunotherapy. The patient had a triad of “ataxia, areflexia and ophthalmoplegia”. Cerebrospinal fluid showed protein-cell separation. Serum anti-Sulfatides antibody IgM, anti-GT1a antibody IgG, anti-GQ1b antibody IgG and anti-GM3 IgM were positive. Recurrent MFS was diagnosed and the symptoms improved after immunotherapy. This case suggests that MFS is clinically heterogeneous, a few patients can present with relapse and generally have a better prognosis with immunotherapy. Pre-existing infection and anti-GQ1b antibody production may be predisposing factors for MFS recurrence.

Objective:To compare and analyze the calcification characteristics and diagnostic efficiency of different breast lesion types using digtal breast tomosynthesis (DBT) and full-field digital mammography (FFDM).Methods:Totally 1 263 patients who underwent both DBT and FFDM at the same time from January 2015 to December 2018 in Dahua Hospital, Xuhui district, Shanghai were analyzed retrospectively. Benign and malignant calcification should be confirmed by pathology or a follow-up of 24 months or more using mammography, and the results of DBT and FFDM were taken as a gold standard. The detection rate and diagnostic efficiency of different types of benign and malignant breast calcification with the two methods were compared and analyzed. The detection rate of morphology and distribution of malignant calcification were compared among groups.Results:There were 240 cases with non-dense breast including 56 cases with benign calcification and 13 cases with malignant calcification. Meanwhile, there were 1 023 cases with dense breast, including 356 cases with benign calcification and 63 cases with malignant calcification. In the cases of non-dense breast, the detection rates of benign calcification by DBT and FFDM were 22.9% (55/240) and 21.7% (52/240), whereas the rates of malignant calcification were 5.0% (12/240) and 4.6% (11/240), all without statistically significances（χ2=0.108, 0.046, P>0.05). No significant differences were observed in the morphology and distribution of malignant calcification detection rates ( P>0.05). In the cases of dense breast, the benign calcification detection rates by DBT and FFDM were 34.2% (350/1 023) and 31.9% (326/1 023), whereas the detection rates of malignant calcification were 6.0% (61/1 023) and 4.9% (50/1 023), all without statistically significances (χ2=1.273 and 1.153, P>0.05). DBT detected more cases of amorphous and cluster distribution of malignant calcification than FFDM, with statistically significant differences (χ2=12.921 and 11.667, P<0.05). The area under ROC curve of DBT and FFDM in diagnosis of non-dense breast were 0.993 and 0.992, and 0.987 and 0.964 in dense breast, respectively, with no significant differences ( Z= 0.136 and 1.391, P>0.05). Conclusions:Compared with FFDM, DBT shows no statistical difference in the diagnostic efficiency of breast calcification. However, it has certain advantages in detecting malignant, amorphous, and clustered calcification in dense breast. DBT has a potential to improve the accuracy of BI-RADS classification of breast calcification.

Objective:To investigate the current situation and needs of pharmaceutical training for general practice faculty.Methods:A self-designed questionnaire survey was conducted in April 2019. The participants were general practice faculty attending the national training course in Zhongshan Hospital and selected by convenience sampling method.Results:A total of 219 general practice teachers participated in the survey, 51.14% (112/219) of the participants thought that the current pharmaceutical knowledge did not meet the needs of pharmaceutical services in daily work, and 67.58% (148/219) attended pharmacy related training every year, and the frequency was mainly 1—2 times per year (56.62%, 124/219). The main reasons for attending the training were working needs (68.24%, 101/148) and willingness (55.41%, 82/148); 63.51% (94/148) of the participants thought that the training was moderate or less effective, mainly because of the weak strength of trainers (40.54%, 60/148), insufficient attention paid by trainers (37.16%, 55/148) and lack of depth (37.16%, 55/148). The survey showed that 76.26% (167/219) of general practice teachers had pharmaceutical training needs; and gender, working years and working experience in secondary and/or tertiary hospitals were influencing factors for pharmaceutical training needs. And female faculty, those working less than 10 years and with working experience in secondary hospitals had higher demand for pharmaceutical training. The expected pharmaceutical training focused primarily on the selection and optimization of medication schemes (72.60%, 159/219), interaction/incompatibility between medicines (62.10%, 136/219) and pharmaceutical care in medical treatment (57.08%, 125/219). The expected training methods were mainly interactive case analysis and discussion (69.41%, 152/219) through the internet or APP (such as WeChat) (54.34%, 119/219); the expected training frequency was no more than once in two months (36.07%, 79/219), better in working time (48.86%, 107/219) and each session was 30—45 minutes (38.36%, 84/219).Conclusion:General practice faculty has a high demand for pharmaceutical training. Targeted, individualized and systematic pharmaceutical training courses should be developed according to the pharmaceutical training needs of participants.

Objective:To analyze the risk factors for complications of the retromandibular approach in patients with parotid gland posterior and lower pole tumors.Methods:A retrospective analysis was conducted on the clinical data of 140 patients with parotid posterior lower pole tumors admitted to the Xingtai Third Hospital from October 2019 to October 2021. They were divided into two groups based on whether complications occurred: the occurrence group and the non occurrence group. General data of the two groups of patients were collected, including age, gender, course of disease, previous surgical history, number of tumors, tumor length, resection range, facial nerve dissociation, tumor site resection frequency, and fascia preservation; Single factor and logistic multivariate analysis were conducted to determine the risk factors for complications of the posterior retromandibular approach in patients with parotid gland posterior and lower pole tumors.Results:A total of 140 patients with parotid gland posterior lower pole tumors underwent retromandibular approach treatment, with complications occurring in 38 cases (27.14%), including 7 cases of temporary facial paralysis, 10 cases of facial depression, 11 cases of Frey syndrome, 2 cases of fistula, and 8 cases of sensory abnormalities of the greater auricular nerve. Through logistic multivariate analysis, it was found that the number of tumors ≥ 2 ( OR=2.856), the resection range (total resection) ( OR=2.477), the number of surgeries ≥3 ( OR=5.637), facial nerve dissociation ( OR=3.526), and lack of fascia preservation ( OR=2.551) were all risk factors for postoperative complications in patients with parotid posterior pole tumors (all P<0.05). Conclusions:In clinical practice, relevant prevention and treatment measures should be formulated for these high-risk factors to reduce the incidence of postoperative complications.

Objective: To investigate the clinicopathologic and molecular features of the rare cribriform morular variant of papillary thyroid carcinoma (CMV-PTC). Methods: The clinicopathologic data of 10 patients with CMV-PTC were retrospectively reviewed. Immunohistochemical (IHC) staining was done using LSAB method. DNA sequencing for APC were applied using Sanger method. BRAF V600E mutation was examined using ARMS method. The cytological, morphological, IHC and molecular features were analyzed. Results: All patients were female at an average age of 27 years old. The tumors were mostly located in the right lobe of thyroid. Fine needle aspiration cytology was performed in three patients; two were diagnosed as suspicious for PTC and one as PTC. Nine tumors presented as solitary nodule and two as multiple nodules in both lobes. Infiltration was demonstrated in three cases. The average size was 2.6 cm. The neoplastic cells were arranged in papillary, cribriform, solid and glandular patterns, with rare or without colloid inside the lumen. The number of morula varied, ranging from zero to many. The neoplastic cells were variably enlarged, showing round, oval or spindle shape. Nuclear irregularity was identified as irregular membrane, nuclear grooves or pseudoinclusion, but no typical ground glass feature. Peculiar nuclear clearing could be observed in the morular cells. IHC staining showed the neoplastic cells were negative for thyroglobulin and p63, but positive for TTF1, cytokeratin 19 and estrogen receptor. Diffuse staining with cytokeratin was seen in the neoplastic cells and the morula. Specific cytoplasmic and nuclear staining of β-catenin was seen in the neoplastic cells but not the morula. Ki-67 proliferation index was 1%-30%. No recurrence or metastasis was observed. One patient was demonstrated to harbor both somatic and germline mutations of the APC gene, who was found to have adenomatous polyposis and her mother died of colonic carcinoma. No BRAF V600E mutation was detected. Conclusions CMV-PTC is rare and shows atypical cytological and clinicopathological features, and it is easily misdiagnosed.TG, TTF1, ER and β-catenin are specific IHC markers for CMV-PTC. The morula is negative for cytokeratin 19, in contrast to squamous metaplasia. Although CMV-PTC has indolent clinical behavior, a definite diagnosis is necessary to rule out the possibility of APC gene mutation and related extra-thyroidal neoplasm, such as FAP and Gardner syndrome.
