Objective To explore a new efficient extraction method of dorsal root ganglions(DRGs)of rats by exploring and extracting DRGs reversely along the nerve traveling pathway. Methods The DRGs were extracted by the traditional method of opening the intervertebral foramina and the new method, extracting DRGs reversely along the nerve traveling pathway,respectively. The time consuming and the number of intact DRGs obtained with these two method were compared. Results The number of intact DRGs(L3-5segments,both sides)extracted from each rat with the traditional method was(3.08 ± 1.31),and the average time consuming of each DRG was(5.58 ± 1.21)min. As for the new method ,the number of intact DRGs extracted from each rat was(4.29 ± 1.08), and the average time consuming was(1.69 ± 0.91)min,significantly better than that of the traditional method(P < 0.05 for both). Conclusions The new method of exploring and extracting DRGs reversely along the nerve traveling pathway is more efficient for obtaining intact DRGs of rats,providing more useful tissue materials for subsequent culture and morphological studies of DRG cells.

BACKGROUND:
The aim of this study is to systematically evaluate the efficacy and adverse effects of Lobaplatin and Cisplatin in the treatment of malignant pleural effusion.
METHODS:
The databases of Medline (PubMed), Embase, Web of Science, Cochrane, Wanfang, CNKI and VIP were retrieved so as to search the studies about the randomized controlled clinical trials (RCT) that compared the Lobaplatin and Cisplatin for malignant pleural effusion. The main outcome indicators include objective response rate, complete response, partial response, nephrotoxicity, chest pain, gastrointestinal reaction, myelosuppression, fever response and hepatotoxicity. Relative risk was used as the effect size, which was expressed as 95% confidence interval. The meta-analysis was performed using Stata 14.0 statistical software.
RESULTS:
A total of 12 RCTs and 720 MPE patients were included. The results showed that the ORR (RR=1.27, 95%CI: 1.15-1.40, P<0.001), CR (RR=1.39, 95%CI: 1.09-1.78, P=0.007), PR (RR=1.21, 95%CI: 1.02-1.42, P=0.026) in LBP thoracic perfusion chemotherapy were significantly higher than those in DDP thoracic perfusion chemotherapy. The incidence of nephrotoxicity (RR=0.31, 95%CI: 0.13-0.71, P=0.005) and gastrointestinal reactions (RR=0.44, 95%CI: 0.31-0.62, P<0.001) in the LBP group were significantly lower than those in DDP group.
CONCLUSIONS
Compared with DDP pleural perfusion chemotherapy, the ORR, CR and PR of LBP pleural perfusion chemotherapy for MPE are significantly better than DDP, and its nephrotoxicity and gastrointestinal reactions are remarkably lower than DDP.
