[Objective]To discuss the anatomy and etiology of cubital tunnel syndrome.[Method]The clinical data and surgical findings of sixty five cubital tunnel syndrome cases were analyzed,and the per-operative electromyogram results of twenty five cases were studied.[Result]Hypertrophy of arcuate ligament resulted in compression and abrasion of ulnar nerve in sixty patients;we found that the ulnar nerve conduct velocity decreased(the average speed was 27.97 m/s),motional amplitude also decreased(the average voltage was 1.95 mv),and latent period prolonged(the average time was 5.41 ms)after pre-operative electromyogram.[Conclusion]The major etiology of cubital tunnel syndrome is chronic injury with sustained compression of ulnar nerve around elbow joint.Careful physical examination of ulnar nerve function and pre-operative electromyogram will help us to diagnose the cubital tunnel syndrome.Cubital tunnel syndrome should be differentiated from tardy ulnar nerve palsy of other sites.

AIM: To study the action of Shugan Pills (SHGP) (Fructus Toosendan, Rhizoma corydalis, Radix Paloniae Albe, Radix Aucklandiae, Cortex Magnoliae Officinalis, Fructus Aurantii, etc.) on treatment of epigastralgia. METHODS: The analgesic effect was tested by the hot plate test and writhing method. The anti gastric ulcer action of SHGP was observed on the gastric ulcer induced by water immersion stress, reserpine and absolute ethyl alcohol. The effect on gastric secretion in rats was studied with pylorus ligation. The effect on gastrointestinal motility was observed by determination of gastric emptying and small intestinal propulsion ability in mouse. RESULTS: SHGP enhanced hot pain threhshold and decreased the number of twisting body in mouse. SHGP markedly inhibited gastric ulcer induced by water immersion stress, reserpine and absolute ethyl alcohol. SHGP significantly inhibited the secretion of gastric acid and pepsin and promoted the secretion of gastric mucus. SHGP markedly delayed gastric emptying in normal mouse and when gastric emptying and small intestinal propulsion was stimulated by neostigmine. SHGP faintly strengthed the effect of atropine on inhibition of gastrointestinal motility. CONCLUSION: Shugan Pills could have analgesic effect, anti gastric ulcer action, it inhibited the secrection of gastric juice and the activity of gastric smooth muscle. These effects might be the pharmacological mechanisms of SHGP on treatment of epigastralgia.

How does brain select and adjust the distributed neural activities to achieve its function? To address this problem,researchers introduce Granger causality analysis method to brain functional study,which deals with the estimation of causal influences among multi-variables.First,basic principles of Granger Causality and its improved algorithm structural vector autoregression (SVAR) are introduced.Then several technical problems are reviewed which should be noted when analyzing brain functional signals by Granger Causality Methods.In the end,the application foreground of Granger Causality in epilepsy localization is introduced by taking idiopathic generalized epilepsy as the example.

Objective To study the changes of white matter fiber tracts in mild traumatic brain injury(mTBI)patients by using DTI technique on 3.0T MR system,and evaluate the clinical diagnostic value of DTI.Methods Thirty mTBI and 30 matched health-y controls underwent conventional CT,MRI and DTI examinations.FA values and ADC values in the genu of the corpus callosum, the splenium of the corpus callosum,bilateral internal capsule,the cingulum bundle,the bilateral superior longitudinal fasciculus and the inferior longitudinal fasciculus of mTBI were measured in mTBI patients and controls at acute phase,subacute phase,5 weeks and 3 months post-trauma.The temporal changes of MRI data were observed.Results The FA values in the part of the white mat-ter fiber tracts reduced in the acute and subacute phase in mTBI patients (all P <0.05)in relative to controls (all P <0.05),At 5 weeks and 3 months post-trauma,the FA values also slightly lower in patients than controls.As for the genu of the corpus callosum and the splenium of the corpus callosum,the FA values in mTBI patients increased slightly at the acute stage (all P >0.05),but de-creased at 5 weeks-3 months post-trauma phase,though there was no significantly difference(all P >0.05).ADC values significantly decreased in the acute and subacute phase in mTBI patients,while they recovered thereafter (all P >0.05).Conclusion The sensi-tivity of DTI in detecting the lesions of mild traumatic brain damage is high,and it can display the damage of white matter.DTI could play an important role in the diagnosis of mTBI.

Objective To study effects of multimodal analgesia on postoperative delirium (POD)in elder patients with hip fracture.Methods One hundred and eight elder patients with hip fractures were gathered in a prospective study.Fifty-nine cases were included in the group of multimodal analgesia (25 males,34 females),with an average age of 72.91±5.42 years,and 35 were treated with hip replacements,the other 24 were internal fixations.Forty-nine cases were in the group of conventional analgesia (22 males,27 females),with an average age of 72.14±4.93 years,29 were treated with hip replacements,20 were internal fixations.Assessments of delirium were based on confusion assessment method.Local infiltrated anesthesia,patient control intravenous analgesia,and intravenous nonsteroid anti-inflammatory drug were applied in the group of multimodal analgesia.For the other group,morphine would be given only when patient complained pain or there was POD.Postoperatively,visual analogue scale (VAS),onset of delirium,other correlative data were recorded by an independent researcher.All patients underwent POD were managed with intensive pain management,and then reevaluated.Results VAS in multimodal analgesia group [Day1:2.10±1.43(resting),4.74±1.45 (active) and Day 3:1.01±0.92 (resting),3.31±1.36 (active)] were significandy lower than that in the other group [Day1:4.67±1.33 (resting),7.44±1.59 (active)and Day 3:2.24±1.39 (resting),5.06±1.46 (active)].PODs were detected in 15 (30.6％) in group of conventional analgesia; while in group of multimodal analgesia,there were 7 (11.9％).All POD were given intensive pain managements by injection of 10 mg morphine and achieved relief of deliriums.Conclusion Postoperative multimodal analgesia may reduce the incidence of POD.First aid of intensive pain management may help to control POD.

Purpose To investigate the diameter change of dorsal root ganglion (DRG) in lumbar disc herniation using three-dimensional MR neurography. Materials and Methods Sixty-ifve patients with lumbar disc herniation and 30 healthy volunteers were selected. Bilateral DRG diameter was measured using MR three-dimensional constructive interference steady state (3D-CISS) sequence at the level of L3-S1 in the control group and at the level of herniation disc in patient group including central and lateral subgroups. The relationship between the sagittal index and DRG diameter at the level of herniation disc was analyzed. Results In the control group, the DRG diameters increased from the level of L3 to S1. The DRG diameters of the central subgroup were bigger than those of the control group (t=-2.485--2.253, P<0.05). The DRG diameters of the lateral subgroup were bigger on the diseased side than the contralateral side (t=1.956-2.432, P<0.05). The DRG diameters of the contralateral side in lateral subgroup were slightly bigger than those of control group without statistical signiifcance (t=-1.248--0.981, P>0.05). The sagittal index was not correlated with DRG diameter. Conclusion 3D-CISS sequence clearly demonstrates morphological changes of lumbosacral nerve root and measures its diameter.

Objective To investigate the expressions of peripheral type benzodiazepine receptor (PBR) and steroidogenic acute regulatory protein (StAR) of testis in rats with chronic ethanol feeding.Methods Forty rats were treated with different ethanol dosages for twenty weeks, the morphology of testis and protein expressions of PBR and StAR were observed.Results In the ethanol-feeding rats, seminiferous tubular wall of testes became thin and the layer of germ cells was significantly reduced, moreover, the broken spermatozoon′s flagella were frequently observed and few integrated spermatozoa were produced.Compared with control group, the protein expressions of PBR and StAR protein were reduced by 13.8%, 20.9%, 50.4% and 34.5%, 37.7%, 95.2% in low-, middle- and high-dose ethanol feeding group respectively by immunoprecipitation.Similarly, both locating at interstitial cells in testes were also decreased by 33.27 %, 37.71 %, 63.59 % and 27.12 %, 51.84 %, 58.41% in the same ethanol feeding groups respectively by immunohistochemistry.Conclusion Both PBR and StAR protein expressions are decreased in interstitial cells of testes in chronic ethanol-feeding rats, which shows positive correlation with ethanol dosage.

To summarize Professor LIU Feng-bin's clinical experience and theoretical thoughts on chronic atrophic gastritis (CAG), the study group designed a retrospective study on his case series and expert interview. First of all, the data of CAG patients treated in the First Affiliated Hospital of Guangzhou University of Chinese Medicine between 2009 and 2013, e. g. herbs, diseases, syndrome type, prescription amount and number of herbs, was collected and processed. The statistical description and binary logistic regression were used to determined the syndrome type, initial basic remedy and modification. During the statistics, a complete and sub-group analysis was performed simultaneously. After the expert interview, the syndrome type and medication were finalized. As a result, a total of 228 CAG patients aged at (50.30 ± 10.18) were collected, including 151 males (66.23%). Of them, the TCM diagnosis and syndrome type were extracted from the information of 157 patients, including 115 cases with gastric stuffiness, 23 cases with gastric pain, 19 missing cases, 2 cases with spleen-stomach weakness syndrome, 57 cases with spleen deficiency and dampness-heat syndrome, 18 cases with spleen-stomach disharmony syndrome, 23 cases with syndrome of liver depression syndrome, 21 cases with liver qi invading stomach syndrome and 26 qi and yin deficiency syndrome, respectively. All of the 228 patients used totally 104 herbs, while the subgroups with 157 patients used 94 herbs. The most frequently used 15 herbs used in each groups were analyzed to determine the initial basic remedy and modification. Subsequently, based on the information of the sub-groups with 157 patients, with the syndrome type as the dependent variable, the logistic regression analysis was made on the most frequently used 32 herbs, in order to determined the modification in herbs for different syndrome types. After experts reviewed and modified, they believed the main causes of CAG were dietary irregularities, moodiness and weak constitution; the pathogenesis of CAG was spleen deficiency with qi stagnation, heat depression and blood stasis in the stomach meridian. The above six syndrome types and 12 herbs were determined, including Pseudostellariae Radix, Poria, Atractylodismacrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Fritillariae Thunbergii Bulbus, Sepiae Endoconcha, Arecae Pericarpium, Aurantii Fructus, Perillae Caulis, Herba Hedyotis Diffusae, Scutellariae Barbatae Herba, Curcumae Rhizoma. This study summarized Professor LIU Feng-bin's clinical experience and theoretical thoughts of chronic atrophic gastritis based on clinical practice data and expert interview, with a rigorous design and good scientificity and practicability.

Objective To synthesize 99Tcm- (hydrazinonictinamide- [Lys3] -bombesin) (tricine)(trisodium triphenylphosphine-3,3',3"-trisulfonate) ((HYNIC-[Lys3]-BBS) (tricine) (TPPTS)) and evaluate its biodistribution and binding capability with tumor tissue in Balb/c nude mice bearing human pancreatic cancer xenografts. Methods HYNIC was conjugated to the [Lys3] -BBS at pH = 9.0 with SnCl2 as reducing agent and both tricine and TPPTS as coligands for 99Tcm-labeling. 99Tcm-HYNIC-[Lys3]-BBS)(tricine) (TPPTS) was purified by Sep-Pak C18 cartridge and was analysed by HPLC. The radiochemical purity and radiolabeling yield were measured. The stability of 99Tcm-(HYNIC-[Lys3]-BBS) (tricine)(TPPTS) in serum, biodistribution (% ID/g) in the normal mice and imaging of the Balb/c nude mice bearing human pancreatic cancer xenografts in vivo were studied. Results The radiolabeling yield was (90 ±2)% and the radiochemical purity was over 95%. The radiochemical purity after 4 h in serum was over 85%. The distribution in normal mice showed rapid clearance from blood (the uptake was (0.07 ±0.01) %ID/g at 2 h postinjection). 99Tcm-(HYNIC-[Lys3]-BBS) (tricine) (TPPTS) was excreted mainly via the kidney with little radioactivity accumulation in the liver and gastrointestinal tract (the uptake of liver, stomach, intestine was (0.27 ±0.03), (0.06 ±0.03), (0.04 ±0.00) %ID/g at 2 h postinjection). Marked uptake of radioactivity was found in tumor tissue of the Balb/c nude mice bearing human pancreatic cancer with maximum T/NT ratio of 3.71 ± 0.57 at 2 h postinjection. Conclusions 99Tcm-(HYNIC-[Lys3]-BBS)(tricine) (TPPTS) can be easily prepared with high radiolabeling yield and radiochemical purity. The stability in serum and good biodistribution charateristics make it useful for the diagnosis of human pancreatic cancer with over-expression of the gastric-releasing peptide(GRP) receptor.
