Objective To evaluate the value of the short-segment nerve conduction studies (SSCSs, inching test) in the diagnosis and localization of cubital tunnel syndrome (CubTS).Methods The clinical and electrophysiologic data of 46 patients (92 limbs from 32 men and 14 women, aged from 19 to 59 years, with average age of 41.2 years) with CubTS were collected.The symptoms occurred in unilateral arm in 41 patients and bilateral arms in 5 patients, involving 35 left arms and 16 right arms.SSCSs were performed in both arms in all the 46 patients.Sixty ulnar nerves were studied in 30 healthy control subjects using SSCSs.Results The 51 symptomatic arms with CubTS were abnormal in long segment motor nerve conduction studies.There were 68 abnormal arms ( 51 symptomatic arms, 17 asymptomatic arms ) in SSCSs.The lesions were located 2 cm proximal to the elbow-the elbow segment ( AE2-E ) in 41 arms (44.6%),the elbow-2 cm distal to the elbow segment (E-BE2) in 23 arms (25%), 4 cm proximal to the elbow-2 cm proximal to the elbow segment (AE4-AE2) in 18 arms (19.6%), 6 cm proximal to the elbow-4 cm proximal to the elbow segment (AE6-AE4) in 9 arms (9.8%), 2 cm distal to the elbow-4 cm distal to the elbow segment (BE2-BE4) in 8 arms(8.6%) and 4 cm distal to the elbow-6 cm distal to the elbow segment (BE4-BE6) in 6 arms(6.5%),respectively.Conclusions SSCSs are more sensitive in detecting CubTS than the conventional long segment motor conduction studies.SSCSs could precisely localize the entrapment lesions in patients with CubTS ,might be a useful tool for the detection of ulnar mononeuropathy at the elbow, especially for diagnosing the patients with CubTS who have no clinical features or have a normal long segmental nerve conduction findings.

OBJECTIVETo compare the efficacy between elongated needle therapy and regular needle therapy at Tiantu (CV 22) on the basis of xingnao kaiqiao (activiting brain and regaining consciousness) acupuncture therapy so as to explore the effective therapeutic method in treatment of dysphagia induced by bulbar palsy.

METHODSSeventy one cases of dysphagia induced by bulbar palsy were randomized into two groups. The xingnao kaiqiao acupuncture therapy was applied at Shuigou (GV 26), Neiguan (PC 6), Sanyinjiao (SP 6) and the others in the two groups. In the elongated needle therapy group, on the basis of xingnao kaiqiao acupuncture therapy, the elongated needle was used to puncture Tiantu (CV 22). In the regular needle therapy, the regular acupuncture technique was used at Tiantu (CV 22). In both groups, the treatment was given once a day in a week except Sunday and lasted for 4 weeks totally. Before and after treatment, the swallowing condition and the standardized swallowing assessment (SSA) were observed in the patients and the efficacy was compared between the two groups.

RESULTSThe total effective rate was 97.2% (35/36) in the elongated needle therapy group, which was better than 77.1% (27/35) in the regular needle therapy group (P<0.05). After treatment, SSA score was reduced significantly as compared with that before treatment in the two groups (both P<0.05). SSA score in the elongated needle therapy group was reduced much more apparently as compared with that in the regular needle therapy group after treatment (P<0.05).

CONCLUSIONOn the basis of the xingnao kaiqiao acupuncture therapy, the elongated needle therapy at Tiantu (CV 22) achieves the superior effect on bulbar palsy-induced dysphagia as compared with the regular acu- puncture at Tiantu (CV 22).

In this paper, the concepts of surrogate outcomes and intermediary outcomes, their correlation with the primary outcome, how to select surrogate outcomes and intermediary outcomes and the particular requirements for using surrogate outcomes in assessing TCM clinical efficacy were discussed and described. It is difficult to evaluate clinical efficacy objectively and thoroughly by means of a single surrogate outcome for reason of the global characteristics of TCM, therefore, to rationally select such intermediary outcomes as important clinical symptoms, combination of several syndromes, patients' subject feeling, patients' satisfaction for treatment and quality of life, should be beneficial for objectively evaluating the efficacy of TCM intervention approaches.
