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.

Conventional angiography has been used to identify detailed vascular anatomy for surgery in which parenchymal salvage should be necessary. Recently, we experienced a case in which 3-dimensional CT was very helpful in salvaging the part of the kidney. A 2 year-old girl was diagnosed as bilateral Wilms` tumor. Conventional CT scan showed right huge mass and left upper pole mass of the kidney. The patient was planned to have neoadjuvant chemotherapy. Spiral CT scan with three-dimensional reconstruction was performed after 3-month chemotherapy and detailed anatomical information regarding vessels, tumor mass and normal parenchyma was obtained. Based on these anatomical information, right radical nephrectomy and left partial nephrectomy was successfully performed. Surgical findings was quite similar to that obtained by preoperative 3-dimensional CT images. Three-dimensional reconstruction of spiral CT imaging is considered to be useful in the evaluation of surgical anatomy in kidney-saving surgery preoperatively.

PURPOSE: To assess the usefulness of radiofrequency (RF) thermal ablation with combined chemotherapy for the treatment of metastatic liver tumors. MATERIALS AND METHODS: A non-randomized, comparative study was performed in 21 patients with metastatic liver tumors. Inclusion criteria were that these should be less than five in number and less than 6 cm in diameter. Two groups were designed for comparison of the local and remote (new intrahepatic or extrahepatic) tumor control rate (Group A: RF alone, n=11; Group B: RF+combined chemotherapy, n=10). There was no significant difference in age, sex, and mass size between the two groups (p>0.05). All ablations were performed percutaneously with a 50W RF generator and 15G-needle electrode (RITA Medical System Inc.) under US guidance. In group B, six cycles of systemic chemotherapy were performed every month immediately after RF ablation. Follow-up CT scans were obtained within 24 hours of ablation and were compared with the findings of pre-ablation CT scanning. If an ablated lesion covered the mass without any residual enhancing foci, this was defined as complete ablation. Three and six months after ablation, local and remote tumor control rates were compared between the two groups (follow up: range 4 -17 (mean, 10.2) months. RESULTS: In group A, the local tumor control rate was 43.8% (7/16) and 31.2% (5/16) at 3 and 6 months follow-up, respectively, while in group B, the corresponding rates were both 75% (15/20). At three months, the difference in this rate between the two groups was not significantly different (p>0.05), but at 6 months there was significant difference (p<0.05). At 6 months follow-up, the remote tumor control rate for Group A and Group B was 27.3% (3/11) and 80.0% (8/10), respectively, reflecting a significant difference between the two groups (p<0.05). CONCLUSION: In patients with metastatic liver tumor, radiofrequency thermal ablation with combined chemotherapy may be superior to RF thermal ablation alone for both local and remote tumor control.

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.
