Objective To assess the type and prevalence of residual symptoms in Chinese depressive patients after acute phase treatment and the impact on the quality of life and social function. Method It was a nationwide, multi-center survey. A total of 11 sites participated and 1503 outpatients with major depressive disorder who subjectively self-reported a least 50%improvement after 8-12 weeks of antidepressants treatment were included in this study. Brief 16-Item Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR16), Patient Health Questionnaire-15 (PHQ-15), Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF) and Sheehan Disability Scale (SDS) were used to assess the symptoms and function. Results Altogether 48.8%(733/1503) of patients who self-reported an improvement after acute-phase treatment still presented with residual symptoms (QIDS-SR16>5). The most common residual symptoms (QIDS-SR16≥1) were poor concentration/decision making (82.4%, 604/733), low energy (79.7%, 584/733), loss of interest (75.2%, 551/733), sad mood (72.4%, 531/733) and mid-nocturnal insomnia (72.3%, 530/733). The patients with severe residual symptoms had higher PHQ-15 total score (t=-10.55,P<0.01), lower Q-LES-Q-SF score (t=10.20,P=0.010) and higher SDS score (t=-13.22,P<0.01). Conclusion The great majority of patients who self-report an improvement after acute phase antidepressant treatment may still have residual symptoms. The severity of residual symptoms is associated with significant function impairment and poor life satisfaction.

Objective To explore the effect of early application of pediauic amino acids on extrauterine growth and development of preterm and small for gestational age infants.Methods A total of 106preterm and small for gestational age infants was selected in our NICU from June 2011 to May 2013,and randomly divided into two groups:treatment group (group T) and control group (group C).Next,each group was divided into two subgroups according to gestational age and birth weight.Such as ≥34W group (group T1,group C1),＜ 34W group (group T2,group C2),＜ 1.5 kg group (group T3,group C3) and ≥ 1.5 kg group (group T4,group C4).They were observed the effect of extrauterine growth and correlative serum biochemical indicators with application of pediatric amino acid in postnatal 6 hours and 12 hours.Resuits After 2-week treatment,the head circumference and weight growth of group T were higher than that of group C (P ＜ 0.05,or P ＜ 0.01),and the time of birth weight recovery was significantly shortened(P ＜ 0.05,or P ＜ 0.01).The incidence rate of extrauterine growth retardation(EUGR) in the group T was lower than that in group C,there is significantly statistical differences(P ＜ 0.01).The concentration of blood urea nitrogen (BUN) in group T was obviously increased than that in the group C(P ＜0.01).The levels of ALT,aspartate aminotransferase (AST),total bilirubin (TBIL),cholesterol (CH) and triglycerides (TG) were not different between the group T and group C.The comparison of alanine aminotransferase (ALT) levels were statistically significant between group C4 and group T4.In the different gestational age groups,the concentration of BUN in group T was obviously higher than that in the group C after 2-week treatment(P ＜0.05),the levels of AST,TBIL,CH and TG were not different between the group T and group C (P ＞ 0.05).The incidence rate of EUGR in the 4th group C was increased significantly than that in the 4th group T(P ＜0.05).Conclusions The preterm and small for gestational age infants were safe after the pediatric amino acid was used at the 6 h after birth.Amino acid can promote growth of head circumference and weight,shorten the birth weight recovery time and reduce the incidence of EUGR.

Objective To investigate the role of Hedgehog pathway in hepatic fibrosis and its association with activation of hepatic stellate cells. Methods Twenty male Spragur-Dawley rats were divided into control and model groups with 10 each. The animal models were induced by injection with CCl4 and fed with fat-rich diet. The rats in both groups were sacrified at the 8 week with 5 each and the liver tissues were removed for HSC-T6 culture. The deposition of collagen fiber in liver was detected with HE and Masson staining. RT-PCR was used to detect the expressions of Sonic hedgehog (Shh), smoothened (Smo), patched (Ptc), Gli-1 and α-smooth muscle action (α-SMA) mRNA in HSC-T6 and liver tissues. The influence of cyclopamine (Cyc) and lipopolysaccharide (LPS) on HSC-T6 proliferation were assayed by MTT. The expressions of Shh, Smo, Ptc, Gli-1 and α-SMA mRNA after intervention with Cyc (100μmol/L) and LPS were measured by real-time PCR. Results A lot of lipo and collagen deposited in liver of model rats. The Shh,Smo,Gli-1 and α-SMA mRNA were highly expressed in model rats than those in control group (2-△△Ct were 20.45±3.31 vs. 1, 12.78 ± 0. 53 vs. 1, 10.88 ± 2.41 vs. 1, 4.91 ± 2. 59 vs. 1, respectively, all P value <0. 05). In vitro Cyc inhibited HSC-T6 proliferation in dose dependant manner (F=636.81, P<0.01). Compared to the control group, the mRNA expressions of Smo, Ptc, Gli-1,α-SMA in HSC-T6 were significantly reduced after Cyc intervention (2△△Ct, were 0. 20±0. 11, 0. 21 ± 0. 08, 0. 28 ± 0. 05,0. 27±0.10,respectively, all P values<0.01). Conclusion The expression of members of Hedgehog pathway are increased in the progress of hepatic fibrosis, which may accelerate the hepatiee fibrosis by activating HSC.

[Objective] To investigate the height change of intervertebral space after anterior cervical fusion and its relation to neck axial symptoms.[Method]Totally 122 patients receiving anterior cervical fusion were followed up for 2 to 5 years,average 3.9 years.The height change of intervertebral space of the fused segment on X-rays were evaluated before,3 months and 2 years after operation.All patients were classified into 3 groups by means of the postoperative height change of intervertebral space.The axial symptoms after operation were observed and analyzed during follow-up.[Result]The incidence of neck axial symptoms was 54.55%,25.84% and 45.45%,respectively.There were significant differences in statistical analysis in group A group B,group B to group C(x2=7.18,P0.0125).[Conclusion]There is significant relation between height change of intervertebral space and neck axial symptoms after anterior cervical fusion.

On the intact and awake rat, the flexion reflex potential (FRP)and dorsal root potential (DRP) induced by stimulation of the cutaneous nerve with graded intensity stimulations to the sural nerve (a pure cutaneous nerve) were observed, there appeared A-FRP and C-FRP one after the other on the hamstring nerve (a group of nerves innervating the hindlimb flexors), and A-DRP and C-DRP on the L_5 dorsal root at the same time. The threshold and the latencices of A-FRP and A-DRP had no differences, and had significant positive correlations. The amplitudes of A-FRP and A-DRP increased simultaneously with the increase of the stimulating intensity in certain range. The threshold and latency of C-FRP are larger than those of C-DRP. The threshold and the latency of the C-FRP and C-DRP showed significant positive correlation. The amplitudes of C-FRP and C-DRP increased simultaniously with the increase of the stimulating intensity in certain range. The train stimuli (three pulses, 5ms interval, 0. 5ms duration) induced larger FRP and DRP than those induced by single stimulus. Thus, FRP and DRP both have the property of temporal summation.

Deseription was given of the effect of electric acupuncture of Neiguan point on the flexion reflex potential (FRP) of the hindlimbs and the dorsal root potential (DRP). On the intact and awake rats, the graded train stimulation (three pulses, 5ms interval, 0.5ms duration) was given to the sural nerve (a pure cutancous n(?), the C-FRP and C-DRP with their proper amplitudes (70～80% maximum) were obtained on the hamstring nerve (a group of nerves innervating the hindlimb flexors) and L5 dorsal root respectively. Then the electric acupuncture with low freqency and low intensity (4Hz, 1～3V)and low freqency and high intensity ( 4Hz, 20～40V), lasting 5 minutes, was given to the ipsilateral Neiguan point. After acupuncture, the amplitudes of both C-FRP and C-DRP decreased without change of their latebcues. The former one declined heavier and recovered slower than the latter one did. The A-FRP and A-DRP were not affected. Te result of the experiment suggests that the ipsilatcral Neiguan point cletric acupuncture can induce hindlimb's analgesia, the presynaptic inhibition might be involved in the mechanism of such analgesia.
