OBJECTIVETo provide reference for the safe needling depth of Dazhui (GV 14), Jianzhongshu (SI 15), Xuanshu (GV 5) and Mingmen (GV 4) in clinical acupuncture and moxibustion treatment.

METHODSThirty-two adult volunteers were divided into 3 groups, thin person group, moderate person group and fat person group according to Luo's indexes, and computer-aided tomography was used to measure the needling depth of Dazhui (GV 14), Jianzhongshu (SI 15), Xuanshu (GV 5) and Mingmen (GV 4).

RESULTSThe safe depths of perpendicular needling were different for persons of different somatotypes, for example the needling depth for Dazhui (GV 14) was (32.86 +/- 3.96) mm for the thin person group, (37.76 +/- 4.91) mm for the moderate person group, and (47.93 +/- 5.30) mm for the fat person group.

OBJECTIVETo study on safe depth and angle of needling lumbar Jiaji (Ex-B2) for treatment of prolapse of lumbar intervertebral disc.

METHODSCT technique was used for scanning investigation on the depth and angle of needling lumbar Jiaji (Ex-B2).

RESULTSWhen the acupuncture needle or puncture needle was inserted at an angle of 20-30 degrees to the sagittal plane of the human body, the tip of needle could reached to extradural posterior space of the depth of lumbar Jiaji points (being the best inserting depth), in which catgut or medicine could be placed.

CONCLUSIONAcupuncture or catgut stimulating the extradural posterior space at the depth of lumbar Jiaji is superior to the traditional needling method in treatment of prolapse of lumbar intervertebral disc.

With the popularization of chest computed tomography examination in physical examination, the detection rate of multiple pulmonary nodules has significantly increased. However, there are no unified guidelines or consensus for the diagnosis and treatment of multiple pulmonary nodules, and the clinical diagnosis and treatment of such patients are often inadequate or excessive. Therefore, it is of great clinical significance to attach importance to the moderate diagnosis and treatment of multiple pulmonary nodules and formulate unified clinical practice standards for the prevention of lung cancer and the diagnosis and treatment of multiple pulmonary nodules.

BACKGROUND AND PURPOSE: Non-contrast brain computed tomography (NCCT) remains the most common imaging modality employed to select patients for thrombolytic therapy in acute ischemic stroke. The current study used the Alberta Stroke Program Early CT Score (ASPECTS) to identify early ischemic changes on brain NCCT imaging with the aim to investigate whether a relationship exists between time from symptoms onset to NCCT with the presence of early ischaemic change quantified by ASPECTS. METHODS: We studied 1,329 ischemic stroke patients who had NCCT within 8 hours of stroke onset. Patients were assessed to see if they had any ASPECTS lesion and if the rate of patients with a lesion increased with time using logistic regression. RESULTS: 30% patients had an ASPECTS < 10 within the first 3 hours from symptom onset. Within the first 3 hours, the odds for a CT change (ASPECTS < 10) per minute of time was 1.00 with 95% confidence interval (CI) (0.99 to 1.00) (P=0.266). After 3 hours, there was a significant increase in odds of ASPECTS < 10 with increasing time. The odds of being ASPECTS positive increased 1% (odds ratio=1.01) per 1 minute of time with 95% CI (1.00 to 1.01) (P=0.002). CONCLUSIONS: We have identified that prior to first 3 hours of stroke there was no effect of time on odds of CT ischemic change; after the first 3 hours of stroke the odds increased with increasing time to CT scan. The occurrence of early ischemic change may be a marker of time from stroke onset rather than severity.

Malignant melanoma is considered as one of the tumor originated from precancerous melanosis and predilected in the iris and choroid. The Authors experienced a case of malignant melanoma affecting the upper palpebral conjunctiva in 39 year old female. The tumor mass was excised radically and followed by X-Ray therapy. Slight opacities of lens body is developed after X-ray irradiation.

We conducted a pilot study to evaluate the possibility that the intra-arterial thrombolybolytic therapy might lead to recanalization of the acutely occluded cerebral arteries and subsequent clinical improvement in patients with acute ischemic stroke. Mean time from the onset of symptoms to the start of treatment and mean dosage of thrombolytic agent, Urokinase, were 6.4 hours and 120.3 X 10(4) units respectively. Seven of 12 cases with acute ischemic stroke demonstrated successful recanalization; 5 cases achieved complete recanalization; 2 cases partial recanalization, and remaining 5 cases did not show any evidence of recanalization. Neurological evaluation at 1 week and 3 months after the onset of symptoms suggested better outcome in a cases with recanalization. Repeat CT scan at 24 hours and 1 week after the procedure demonstrated evidence of hemorrhagic transformation in the infarcted territories in 5 cases(all in recanalized group), but clinical deteriorations were observed in only 2 case. Though statistical analysis could not be done because of the limited number of cases, these results suggest that the intra-arterial thrombolytic therapy had a role in the management of acute major carebral ischemic stroke.

PURPOSE: The purpose of this study was to analyze the CT findings of hepatoblastoma before and afterchemotherapy, and to compare them with surgical and pathologic features. MATERIALS AND METHODS: Twelvehepatoblastoma patients underwent chemotherapy prior to surgery; in all cases, CT scanning was performed beforeand after chemotherapy. We reviewed the findings with special attention to changes in tumor volume, the extent andpattern of contrast enhancement, the extent of low-attenuation area in the tumor, the presence of a septum, andcalcification or ossification within the mass before and after chemotherapy. Post-chemotherapy CT findings werecompared with operative and pathologic findings. RESULTS: After chemotherapy, the volume of the tumor massdecreased in all patients, and the extent of involved segments decreased in nine(75%), the non-enhancing areawithin the mass, on the other hand, increased in nine (75%). On pre-chemotherapy CT, calcifications were detectedin seven patients(58%), and on post-chemotherapy CT, in nine (75%); the extent of calcification increased in sevenpatients. On the basis of CT findings, viable tumor and necrosis areas could not be distinguished. Massivecalcification or an osteoid mixed with loose connective tissue was noted in the mesenchymal component of thetumor; the whirling pattern of enhancement within the area of low density asen on CT scanning corresponded toosteoid mixed with loose connective tissue, which contained rich blood vessels. CONCLUSION: We describe the CTfindings of hepatoblastoma both before and after chemotherapy, highlighting the changes which occurred. Anunderstanding of these changes is helpful for the proper management of this condition.
