Objective To investigate the value ofsomatosensory evoked potentials (SEP) in early diagnosis of cervical spondylotic radiculopathy (CSR). Methods The median nerve SEP (SEPm) was examined in 65 cases of CSR (experimental group), and was compared with 30 controls(control group). All the patients were examined by MRI of the cervical spine which were compared with SEPm. All cases were followed up 12 months, at the same time MRI and SEPm were examined repeatedly. Results The experimental group with CSR had significantly prolonged peak latency (PL) of N11 and N13 wave and interpeak latency(IPL) of wave N9-NI3 within 3 months [( 12.92 ± 0.97), (14.81 ± 1.16), (4.45 ±0.65)ms] and at the 12th month [( 14.20 ± 1.06), ( 16.35 ± 1.75), (5.62 ± 0.88) ms] compared with those of control group[(11.65 ± 0.69), (13.26 ± 0.78), (3.56 ± 0.31 ) ms](P＜ 0.05). The PL of Nll and N13 wave and IPL of wave N9-N13 significantly prolonged at the 12th month compared with those within 3 months.SEPm provided more sensitive modality for the diagnosis[87.69%(57/65 )] of CSR within 3 months than that of MRI [70.77% (46/65)] ( X2 =4.35,P ＜0.05). While there was no significant difference in sensitive between SEPm [90.77%(59/65)] and MRI [81.54%(53/65)] at the 12th month (X2= 1.56,P＞0.05).Conclusion SEP is valuable for the early diagnosis of CSR and may be clinically utilized as a sensitive indicator of CSR.

Objective To observe the effects of aging on liver and heat shock protein (HSP)70 expression in rats,and explore the role of HSP 70 in the changes of aging liver. Methods 24 healthy Sprague Dawley rats were divided into 4 groups according to age:21-day-old group,3-monthold group,12-month-old group and 18-month-old group (n=6 per group).Routine blood tests and biochemical tests were tested. Liver tissues were observed under light microscopy. The mRNA expression of HSP70 was detected by real-time PCR. Results The ratios of liver weight to body weight were decreased gradually with aging in 4 groups (0.073,0.050,0.025,0.019,respectively,t=78.016,P =0.000).Compared with those of young rats (21-day-old and 3-month-old),serum albumin levels of aged rats (12-months and 18-months) were declined [(35.0±2.7) g/L and (39.8±3.5) g/L vs.(27.3±9.3) g/L and (20.6± 1.7) g/L,t=12.233,P=0.000].Nevertheless serum alkaline phosphatase (ALP) levels were increased with aging [(68.8± 23.3) U/L,(71.6 ± 19.2)U/L,( 185.9 ± 41.5) U/L,(418.6 ± 140.6) U/L,respectively,t =35.454,P=0.000].The differences in other routine biochemical indexes were not found among the age groups (P＞0.05).Liver histological changes including hepatocytes disordered and vacuolization or fatty changes were detected with aging,especially in 18 month-old rats. Real-time PCR results indicated that the expression level of HSP70 mRNA was much lower in 18-month-old rats than in 12-month-old and 3-month-old rats (0.218 vs.0.220 and 0.230,P=0.000). Conclusions HSP70,as a stress protein,may play an important role in the procedure of injury and senescence of liver cell,and then can serve liver aging as one of the influential markers.

The safety of drugs has been the important issue that has caught the mutual attention of clinicians and patients. Kidney is one of the important organs in drug metabolism. The study is based on hospital information system (HIS) data from 20 nationwide general hospitals, indicated by Scr and BUN. Generalized boosted models (GBM) based on propensity score method were used to balance confounding factors. The study contrasts changes on renal function between used Shuxuening injection patients and the unused to explore whether Shuxuening injection affects renal function in clinical. The results showed that Shuxuening injection is likely to affect Scr in logistic regression (P value is 0.035); after the logistic regression based on propensity score method (P value became 0.513, 0.590), no differences were found between the two groups; before and after the logistic regression based on propensity score method (P value was less than 0.05), Shuxuening injection possibly affects BUN. Nevertheless, this study is a retrospective analysis. Logistic regression based on propensity score method can control the known confounding factors very well, while there may be the unknown ones. Therefore, the further exploration is required to monitor whether Shuxuening injection affects really BUN, which will provide clinical guidance for Shuxuening injection safe application.
