Stepping up clinical consultation control is an effective way to improve the level of patient care and medical quality. A retrospective analysis of relevant clinical data led to the discovery that among the leading causes of clinical misdiagnosis and mistreatment were limitation in the scope of knowledge on the part of specialized physicians, inadequate collection of medical record data, over-reliance on accessory examinations, and one-sided clinical thinking. It is pointed out that stepping up clinical consultation control is of great importance as it can help solve clinical difficulties and raise the rate of accuracy in diagnosis; promote professional exchange and raise the rate of success in emergency treatment; cultivate and enhance young doctors expertise in diagnosis and treatment; protect the interests of patients and reduce medical disputes. The paper also puts forward measures for improving and implementing the system of clinical consultation: revising consultation criteria, standardizing consultation procedure, strengthening consultation supervision, and setting up a system of consultation result follow-up and retrospective case discussion.

Aim To investigate the gender differences in electrophysiology and neuroanatomy of myelinated and unmyelinated visceral and baroreceptor afferent neurons(VANs and ABNs) of adult rats.Methods VANs and ABNs were isolated enzymatically and Vagus-nodose slice preparation was also applied in this study.For identification of ABNs,aortic depressor nerve(ADN) was labeled using fluorescent dye.Whole-cell patch technique was used to record action potential(AP).Electronic microscopy was selected for morphological analysis of ADN.Results(1) A-and C-type VANs were identified and significant differences of AP discharge profiles between female and male were not established;(2) except for the traditionally classified A-and C-types,myelinated Ah-type VGNs were also identified with faster conduction velocity,lower firing threshold,and higher neuronal excitability.Importantly,these Ah-types were found in female rats with a similar frequency like A-types but rarely seen in males.(3) Ah-type ABNs were also identified by fluorescence.(4) Morphological data showed that myelinated fiber in ADN was ~25% of total and this result was consistent with our electrophysiological data.(5) Firing frequency of Ah-types(20~40 Hz) was lowered than that of A-types(40~150 Hz,P

Objective To study whether focal mild hypothermia can prolong the therapeutic time window in ischemic stroke, and inquire into the protection mechanisms of focal mild hypothermia on cerebral ischemia. Methods The focal cerebral ischemia and reperfusion model of rats was achieved by intraluminal middle cerebral artery occlusion (MCAO). The adult rats were randomly divided into sham-operation group, normothermia ischemia and reperfusion group and hypothermia ischemia and reperfusion group. The two ischemic groups were respectively further divided into 5 subgroups (subjected ischemia for 2, 3, 6, 8 and 12 h respectively and then all reperfused for 4 h, n=14 per time point). Brain mild hypothermia was achieved 30 minutes after ischemia and maintained to reperfusion period. The neurological deficit scores were assessed. The infarct volumes were evaluated by TTC staining and measured with a computerized image analysis system. TUNEL method was used to observe the neuron apoptosis. The expressions of NF-?Bp65 and NF-?BP65mRNA were detected by immunohistochemistry and hybridation in situ. Results The infarct volumes of hypothermia group were respectively (57.39?37.62) mm~3, (74.09?61.00) mm~3, (81.26?25.46) mm~3, (87.43?54.81) mm~3 and (111.10?43.67) mm~3, which saw significant reductions of 63%, 55%, 56%, 70% and 63% as compared with the normothermia group. In comparison with the normothermia group, focal mild hypothermia also greatly reduced the neurological deficit scores (P

By reverse transcription-polymerase chain reaction (RT-PCR), an open reading frame of pathogenesis-related protein 1 (PR1) was isolated from Panax notoginseng and named as PnPR1. Molecular and bioinformatic analyses of PnPR1 revealed that an open reading frame of 501 bp was predicted to encode a 166-amino acid protein with a deduced molecular mass of 18.1 kD. Homology analysis showed that the deduced amino acid sequence of PR1 protein of Panax notoginseng had a high similarity with other higher plants had the same conservative structure domain of cysteine-rich secretory protein (CAP). The recombinant expressed plasmid pET28a(+)-PnPR1 was expressed in Escherichia coli BL21. The expression conditions were optimized by induction at different times, different temperatures, different IPTG concentrations and different giving times. The optimum expression condition was 0.4 mmol.L-1 IPTG at 28 degrees C for 20 h. The successful expression of PnPR1 provides some basis for protein purification and preparation of the monoclonal antibody.

Objective To explore the biomechanical function of PCL and its different bundles and examine the biomechanical impact of posterior cruciate ligament (PCL) integrity on the medial femoral condyle. Methods Twelve fresh human cadaveric knee specimens were subjected to different axial load (0-800 N) at 0°, 30°,60°, and 90°of knee flexion. Four surgical treatments were carried out for biomechanical testing: PCL intact, anterolateral bundle (ALB) rupture, posteromedial bundle (PMB) rupture and PCL rupure. During the test, strains of middle part of the medial femoral condyle were calculated. Results At O°knee flexion, increasing strain of the medial femoral condyle was detected in PMB rupture and PCL rupture under all loading conditions. No significant difference of strain of the medial femoral condyle was noted between PCL intact and ALB rupture under any loading conditions. Compared to PMB rupture, PCL rupture had not higher strain of the medial femoral condyle under all loading conditions. At 30°, 60° and 90° knee flexion, increasing strain of the medial femoral condyle was noted in ALB rupture under higher loading conditions and PCL rupture under all loading conditions. ALB rupture under lower loading conditions and PMB rupture under all loading conditions did not significantly increased strain of the medial femoral condyle. PCL rupture had higher strain of the medial femoral condyle than ALB rupture under most of loading conditions.Conclusion The data suggest that PMB is the major stabilizing bundle of PCL in full extension, ALB is the major stabilizing bundle of PCL in knee flexion, and both bundles function through the ROM in a codominant fashion. Partial and complete ruptures of PCL may have hazardous biomechanical impacts on the medial femoral condyle during normal movement.

Objective:To evaluate the effect of fluoride on the viability of rat ameloblast HAT-7 cells and calcium concentration in the cells.Methods:HAT-7 cells were exposed to NaF at 0,0.4,0.8,1.6,3.2 and 6.4 mmol/L for 24,48 and 72 h respectively. CCK-8 assay was performed to examine the cells proliferation;the apoptosis rate was determined by flow cytometry;Ca2 +concentration in the cells was detected by laser scanning confocal microscopy.Results:The cell proliferation was increased by NaF at 0.4 mmol/L and 0.8 mmol/L,whereas inhibited at 1.6 mmol/L and above.The effects were in a time-dependent manner.NaF increased apoptosis of the cells and increased Ca2 + concentration in the cells in a concentration-dependent manner.Conclusion:Fluoride at low doses promotes proliferation,at high doses inhibits proliferation of HAT-7 cells.NaF of 1.6 mmol/L or more induces apoptosis of HAT-7 cells and in-duce Ca2 + overloading in the cells.

OBJECTIVE:To observe therapeutic efficacy and safety of Shensong yangxin capsules combined with edaravone in the treatment of cerebrovascular disease complicated with cerebrocardiac syndrome(CCS). METHODS:A total of 128 cerebrovas-cular disease patients with CCS were randomly divided into control group (64 cases) and observation group (64 cases). Control group received routine treatment,observation group was additionally given Shensong yangxin capsule 1.6 g orally,3 times a day+Edaravone injection 30 mg added into 0.9% Sodium chloride solution 250 mL intravenously,2 times a day. Treatment courses of 2 groups lasted for 10 d. Clinical efficacies of 2 groups were observed,and MDA,SOD,catecholamine(NE,E,DA)levels,cT-nI,NIHSS scores,correlation of cTnI level with NIHSS score were also observed before and after treatment. The occurrence of ADR was recorded. RESULTS:Total response rate of nervous system and electrocardio gram in observation group were significant-ly higher than control group,with statistical significance (P<0.05). Before treatment,there was no statistical significance in MDA,SOD,NE,E,DA,cTnI levels or NIHSS scores between 2 groups(P>0.05). After treatment,MDA,NE,E,DA,cTnI levels and NIHSS scores of 2 groups were significantly lower than before,and the observation group was significantly lower than the control group;SOD of 2 groups were significantly higher than before,and the observation group was significantly higher than the antrol group,with statistical significance (P<0.05). cTnI level was positively correlated with NIHSS score (r=0.956,P=0.001). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Based on rou-tine treatment,Shensong yangxin capsules combined with edaravone can significantly improve therapeutic efficacy of cerebrovascu-lar disease patients with CCS,and improve the levels of catecholamine,MDA and SOD without increasing the occurrence of ADR.

Objective:To explore the correlation between serum C1q, thyroid hormone (serum FT 3, FT 4, TSH) and depression by detecting the difference of serum C1q, thyroid hormone (serum FT 3, FT 4, TSH) between depression patients and normal people. Methods:A total of 275 depressive patients(depression group) and 275 healthy controls(healthy group) were recruited.The serum levels of C1q, FT 3, FT 4 and TSH were compared between the two groups.The serum levels of C1q, FT 3, FT 4 and TSH in depression patients with different age, gender, course of disease and HAMD were compared.Further regression analysis was used to evaluate the effects of serum C1q, FT 3, FT 4 and TSH levels on the incidence and severity of depression in patients with depression. Results:Serum C1q, FT 3, TSH of depression group(C1q: 203(165, 239)mg/L, FT 3: (4.39±0.70)pmol/L, TSH: 1.69(1.17, 2.46)mIU/L) were significantly lower than those of healthy group(C1q: (236.25±27.06)mg/L, FT 3: 4.61(4.29, 4.95)pmol/L, TSH: 2.04(1.42, 3.01)mIU/L)(all P<0.01). Compared with the serum indexes in depression group, the level of C1q and TSH in men(C1q : 188.00 (164.00, 221.00) mg/L, TSH: 1.52(1.13, 2.16)mIU/L) were significantly lower than those in women(C1q : 213.00 (168.25, 247.75) mg/L, TSH: 1.85(1.28, 2.57)mIU/L)( P<0.05), and the level of FT 3 and FT 4 in men(FT 3: 4.64 (4.23, 5.06) pmol/ L, FT 4: 16.76(15.05, 18.20)pmol/L) were significantly higher than those in women (FT 3: 4.34 (3.82, 4.72) pmol/L, FT 4: 15.92(14.35, 17.40)pmol/L).
