[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.

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.

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 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.
