Objective:To observe the therapeutic effect of acupuncture-moxibustion at different intervals on persistent allergic rhinitis. Methods: A total of 90 patients conforming to the inclusion criteria were randomized into three groups named A, B and C by randomized block method. Patients in all three groups received the same treatment of acupuncture and herbal cake-partitioned moxibustion at the same acupoints, while the treatment frequency was different. Patients in group A received the treatment once a week, group B twice a week and group C three times a week, and all the treatment lasted for 4 weeks. The total nasal symptom score (TNSS), total ocular symptom score (TOSS) and Sino-nasal outcome test-20 (SNOT-20) were evaluated before and after treatment. The self-rating score of symptoms was evaluated during treatment and 2 weeks after treatment. Results: The total effective rate was 80.0% in group A, 93.3% in group B, and 100.0% in group C. The total effective rate in group A was statistically different from that in group B and group C (both P<0.05), but there was no significant inter-group difference in total effective rate between group B and group C (P>0.05). After treatment, scores of TNSS, TOSS and SNOT-20 in all three groups dropped significantly, and statistically different from those before treatment (all P<0.05); between-group comparison showed group B and group C decreased more obvious than group A (all P<0.05). In self-rating score of symptoms, there were no inter-group statistically significant differences in the first 3-week treatment (all P>0.05); after 4-week treatment, the score in group A was higher than that in group B and group C, and showed statistical significant (both P<0.05); at 2 weeks after treatment, the score in group A was higher than that in group B and group C based on an everyday record, showing statistical significance (both P<0.05). At the 11th day after treatment, the score in group B was higher than that in group C (P<0.05). There were no significant differences between group B and group C at other time points (all P>0.05). Conclusion: All three protocols are effective for allergic rhinitis. With the increase of treatment frequency, the therapeutic efficacy with a treatment frequency of twice a week and three times a week is superior to that of once a week. Frequency of three times a week has a better long-term effect than once and twice a week, together with the least fluctuation of symptoms.

Objective:To investigate the clinicopathological features of gastric adenocarcinoma of fundic gland type (GA-FG).Methods:A total of 12 patients, including 7 cases treated with endoscopic submucosal dissection (ESD), were diagnosed as having GA-FG in Nanjing Drum Tower Hospital from January 2018 to August 2019. Morphological changes were analyzed by reviewing endoscopic and pathological results. Patients were followed up after definitive diagnosis.Results:The clinical symptoms of patients with GA-FG were nonspecific. No Helicobacter pylori infection was identified. The lesions were found in the non-atrophic gastric mucosa of the upper 1/3 portion in 10 cases and middle 1/3 portion in 2 cases. Endoscopically, the most common features were whitish color (9 cases), and all lesions diameter≤1 cm. Their macroscopic types were classified as 0-Ⅰ (2 cases), 0-Ⅱa (9 cases) and 0-Ⅱc (1 case) respectively. All lesions had sharp boundary, with branching dilated blood vessels on the surface. Five in 7 cases who were treated with ESD showed submucosal invasion. Immunohistochemically, 9 cases were classified as the chief cell type , 3 as the mixed type, 11 MUC6 positive, 4 MUC5AC positive, 2 MUC2 positive, and 3 CD10 positive. P53 was detected in all 12 cases, and 9 cases had low Ki-67 staining index (<10%). The mean time of follow-up was 11 months, and 11 patients survived. Conclusion:GA-FG should be taken into consideration when the polyps are found in the upper part of the stomach, with whitish color, and branch dilated blood vessels on the surface. Excellent clinical outcomes can be achieved for GA-FG patients with ESD.

OBJECTIVETo compare the pathologic diagnosis and immunohistochemistry of small cell malignant tumors (SCMT) of bone using both core needle biopsy and surgical specimen.
METHODSSeventy-seven cases of SCMT with core needle biopsies and surgical specimens available were respectively analyzed by histologic examination and immunohistochemical study, with literature review.
RESULTSThe male-to-female ratio was 48:29. The age of the patients ranged from 6 to 73 years. The tumors studied included Ewing sarcoma/PNET (n = 38), myeloma (n = 23), lymphoma (n = 10), small cell osteosarcoma (n = 2), small cell carcinoma (n = 2) and mesenchymal chondrosarcoma (n = 2). The tumors involved limbs, axial skeleton and flat bones. Microscopically, the tumors shared similar histology, with small round cells and spindly cells arranged in diffuse sheets. The pathologic diagnosis by core needle biopsies correlated with that by surgical specimens in 84.4% (65/77) of the cases.
CONCLUSIONSSCMT represents a heterogeneous group of malignancy. Correlations with clinicoradiologic findings and application of ancillary investigations including immunohistochemistry and molecular study are important for definitive diagnosis. Pathologic diagnosis using core needle biopsies shows good results and provides useful information for surgical planning.

OBJECTIVETo investigate the effect of curcumin (Cur) on radiosensitivity of nasopharyngeal carcinoma cell CNE-2 and its mechanism.
METHODThe effect of curcumin on radiosensitivity was determined by the clone formation assay. The cell survival curve was fitted by Graph prism 6. 0. The changes in cell cycle were analyzed by flow cytometry (FCM). The differential expression of long non-coding RNA was detected by gene chip technology. Part of differentially expressed genes was verified by Real-time PCR.
RESULTAfter 10 micro mol L-1 Cur had worked for 24 h, its sensitization enhancement ratio was 1. 03, indicating that low concentration of curcumin could increase the radiosensitivity of nasopharyngeal carcinoma cells; FCM displayed a significant increase of G2 phase cells and significant decrease of S phase cells in the Cur combined radiation group. In the Cur group, the GUCY2GP, H2BFXP, LINC00623 IncRNA were significantly up-regulated and ZRANB2-AS2 LOC100506835, FLJ36000 IncRNA were significantly down-regulated.
CONCLUSIONCur has radiosensitizing effect on human nasopharyngeal carcinoma CNE-2 cells. Its mechanism may be related to the changes in the cell cycle distribution and the expression of long non-coding IncRNA.

The paper reports the systematic study on felodipine and its impurities in tablets, to improve its quality standards for the control of the related substances. HPLC-DAD, UPLC-MS, IR and NMR methods were used for the isolation of felodipine and its impurities in tablets, their identification and the zebrafish animal model was used for the analysis of the toxic impurities. In felodipine material and its tablets, three impurities are isolated and identified. They are impurity 1 [dimethyl 4-(2, 3-dichlorophenyl)-2, 6-dimethyl-1, 4-dihydropyridine-3, 5-dicarboxylate], impurity 2 [ethyl methyl 4-(2, 3-dichlorophenyl)-2, 6-dimethylpyridine-3, 5-dicarboxylate] and impurity 3 [diethyl 4-(2, 3-dichlorophenyl)-2, 6-dimethyl-1, 4-dihydropyridine-3, 5-dicarboxylate], separately. The result of zebrafish animal model analysis showed that the teratogenic effects of four compounds were: impurity 3 > or = felodipine > impurity 1 > impurity 2, lethal effects were as follows: impurity 2 = impurity 3 > felodipine > or = impurity 1. This study confirmed the toxicity of three impurities in felodipine. According to the results, the paper suggested the amendments to the standard of the medicine and provided the support to the control of impurities in the manufacturing process.

OBJECTIVETo study the clinicopathologic features, diagnosis and differential diagnosis of myositis ossificans (MO).
METHODSThe clinical features, radiologic results and pathologic findings of 15 cases of MO (including biopsy and surgical specimens) were analyzed. The hematoxylin and eosin sections were reviewed under light microscope. Immunohistochemical staining for S-100 protein, vimentin, desmin, actin and osteonectin was performed.
RESULTSThe age of the patients ranged from 12 to 46 years. The male-to-female ratio was 11:4. Thirteen cases were located in the parosteum of long bone or subperiosteal soft tissue. The remaining two cases occurred in iliac region and palm, respectively. Five patients had history of injury, while 2 patients had operation before. Four patients had no history of trauma and the remaining one had unknown clinical history. Histologically, zonation pattern was not conspicuous in 10 biopsy cases and 8 corresponding surgical specimens. On the other hand, zonation pattern was observed in 5 biopsy cases and 7 corresponding surgical specimens. Follow up revealed relapses in two patients. Immunohistochemical study showed various degree of positivity for vimentin, desmin, actin and osteonectin. S-100 protein was focally positive in 2 of the cases. The Ki-67 index varied from 1% to 10%.
CONCLUSIONCorrect diagnosis of MO relies on correlation of clinical features, radiologic examination and pathologic findings.
