Objective To investigate the clinical features and incidence of depression in patients with different lo-cations and pathological types of brain tumors. Methods Hamilton Depression Scale (HRSD) was used to assess the de-pression in 140 patients with brain tumor before and after operation. Results The preoperative mean depression rating score was 15.36 ± 6.52 and the prevalence rate of depression was 50 cases (35.7%) in 140 patients with brain tumor. The postoperative mean score of depression was 9.71 ± 5.55 and the prevalence rate of depression was 9 cases (6.4%) in 140 patients with brain tumor. The postoperative depression score and the prevalence rate was significantly decreased after op-eration (P<0.05)(χ2=36.10,P<0.05). The postoperative depression score in either benign or malignant brain tumors was significantly lower after than before operation(all P<0.05)The postoperative depression score in either the left or right or bilateral brain lesions were significantly decreased after than before operation(all P<0.05).Conclusion Pa-tients with brain tumors have different degrees of depression in perioperative. Depression may be associated with brain tu-mour pathological types and lesion sites in patients with brain tumors.

Group-A rotaviruses are recognized as the most common cause of acute diarrhea. Phylogenetic analyses of the VP7 genes of rotaviruses circulating in Nanjing (China) could aid in the development of rotavirus vaccines. A total of 908 stool specimens were collected from patients suffering from acute diarrhea in Nanjing between October 2012 and December 2013, and were tested further for rotaviruses. Fifty rotavirus isolates selected randomly were typed by reverse transcription-polymerase chain reaction using serotype-specific primers for G genotyping. VP7 genes of 19 G9 strains were sequenced for further genetic characterization. Among the 908 stool specimens examined during the surveillance period, 103 (11.34%) were rotavirus-positive. G9 was the most predominant genotype (78.0%), followed by G2, G1 and G3. Sequence and phylogenetic analyses of the VP7 genes of serotype G9 rotaviruses revealed these strains to comprise two lineages (G9-VI, G9-III) and to be dominated by the G9-VI lineage (which belonged to a unique subcluster of Japanese and Chinese G9 strains). Amino-acid sequences of the four antigenic regions (A, B, C or F) were variant among a portion of strains, which may have contributed to the prevalence of G9 rotaviruses in this area.

Autoimmune diseases of the nervous system are a group of diseases caused by the body′s immune system attacking its own nervous system, resulting in structural damage and functional impairment of the corresponding tissues. Interventional clearance of pathogenic auto-antibodies has been shown to be effective in reducing immune damage, inhibiting disease progression and improving prognosis through extensive basic research and long-term clinical practice. The neonatal Fc receptor (FcRn)-mediated circulating protection mechanism of IgG contributes to the long half-life and high plasma levels of IgG. FcRn inhibitors are able to target and block the binding of FcRn to IgG, accelerating IgG clearance and reducing IgG levels. Therefore, the use of FcRn inhibitors in the treatment of autoimmune diseases of the nervous system could theoretically help to accelerate the clearance of pathogenic IgG, achieve good clinical efficacy and have promising applications. Research in this area has made considerable progress in recent years and this article will review this.
