The academic thoughts of Lingnan acupuncture and moxibustion have been an essential part of Lingnan medicine. By exploration and arrangement of Lingnan medicine and books, journals and literatures regarding acupuncture and moxibustion, the ancient and modern acupuncturists and their academic contributions in Lingnan area were reviewed. As a result, the number of Lingnan acupuncturists and their works was low before Qing Dynasty, while from the Republic of China era to People's Republic of China, a considerable amount of acupuncturists emerged with quite a lot of works. By exploration and arrangement of Lingnan acupuncturists and their works and academic opinion, the acupuncture-moxibustion school characterized by Lingnan could be formed and developed.

Effects of six kinds of Chinese herb extracts, including Folium Crataegi extract, Herba Epimedii extract, Folium Acanthopanacis Senticosi extract, Trifolium pratense L. extract, Folium Ginkgo extract and Radix Puerariae extract, on the activities of CYP450 isozymes (CYP1A2, CYP2C, CYP2E1, CYP2D, CYP3A) in rat hepatic microsomals were studied by using a UPLC-MS/MS (MRM) and cocktail probe substrates method. The results showed that effects of six kinds of Chinese herb extracts on each CYP450 isozyme activity were inhibitory. The IC50 of Folium Crataegi extract for the inhibition of rat microsomal CYP2D activity was only for 4.04 microg x mL(-1), which showed the highest inhibition; Trifolium pratense L. extract had strong inhibitory action to CYP2D, the IC50 value was 5.73 microg x mL(-1); Folium Crataegi extract also had strong inhibitory action on CYP2E1, the IC50 value was 10.91 microg x mL(-1). Furthermore, the IC50 of Folium Ginkgo extract for the inhibition of rat microsomal CYP3A, 2D, 2E1 activities were 45.12, 35.45 and 22.41 microg x mL(-1), respectively, and the IC50 of Folium Acanthopanacis Senticosi extract on the inhibition of rat microsomal CYP2E1 activity was 32.89 microg x mL(-1). In addition, mechanism of inhibition experimental results showed that the inhibiting abilities of Folium Crataegi extract and Radix Puerariae extract on each CYP450 isozyme increased with the increasing of the preincubation time, therefore, the inhibitory effects were a mechanism-based inhibition.

Objective To explore the surgical procedures and effects for recurrent scalp dermatofibrosarcoma protuberans (DFSP).Methods Retrospective review was conducted in 7 scalp recurrent DFSP cases in the past 3 years.Intraoperative frozen section analysis of surgical margins was performed.Wide local excision with margins of 3 cm or more was applied,and excision of the skull external lamina or the entire layer of the cranial bones was performed once the skulls under the tumors were invaded.Frozen section analysis was again performed on all the margins.Secondary wound was repaired with local skin flap or fascial pedicled flaps.Surgically removed tumor was paraffin-embedded for HE-staining and immunohistochemical analysis.Results All of 7 tumor specimens were proved recurrent DFSP with histologic findings of intraoperation or postoperation.7 patients were all performed with wide local excision with margins of 3 cm or more,also with skull excision (5 cases with excision of skull external lamina and 2 cases with excision of the entire layer of skull).Negative margins were confirmed with intraoperative frozen sections or postoperative paraffin-embedded sections analysis were confirmed.Immunohistochemical analysis demonstrated that Ki-67 was all positive and CD34 was partially positive in 7 cases.No tumor recurrence or metastasis had been observed in any of our patients after a median follow-up duration of 17 months (range 15-41).Conclusions Wide local excision together with the skull invaded by tumors completely is effective surgical treatments for recurrent scalp DFSP; Use of scalp transferring technique could improve wound repair after complete tumor excision.

Objective To analyze the characteristic and the clinical application of high -frequency stimulation ABR for the patients with unilateral sudden deafness .Methods 40 patients aged 17~45 with unilateral sudden deaf-ness(40 health ears ,subject group)and 20 normal volunteers (40 ears ,control group)were selected to receive high and low frequency stimulation ABRs and pure tone audiometry .Results There were no statistical differences be-tween subject group and control group in pure tone audiometry .The wave Ⅰlatency of high -frequency ABR was longer in the subject group than that in the control group(P<0 .001) .The abnormal rate of Ⅰ - Ⅴ interval between high and low frequency stimulation ABRs was 62 .5% (25/40) in the subject group ,and 5% (2/40) in the control group .There were statistical differences between the two groups (χ2 =29 .574 ,P<0 .001) .Conclusion The waveⅠlatency of high-frequency ABR was longer and the abnormal rate of Ⅰ - Ⅴ interval markedly increased in the health ear of patients with unilateral sudden deafness .This may suggest that the contralateral ear may have an ab-normal blood supply of the inner ear when single side sudden deafness happened .High frequency stimulation ABR can be used to detect the potential changes of contralateral ear before the hearing loss occurred .

In forensic case, the location diagnosis determination of drowning has been one of the most important and dififcult diagnosis. Then diatom test is considered to be a relatively reliable method for the diagnosis of drowning. According to community characteristics inferred from diatoms into the different water region has been credibility. The study of the diatoms in different waters identiifcation is reference to the determination of the body drowned into the water area. In this paper, the research progress of diatom relevant biological characteristics and test methods on review for forensic workers is related to the further research and reference case in practice.

Objective: To establish HPLC fingerprints of Lagotis integra and Lagotis brevituba which were contained in National Drug Standard and compared to Lagotis ramalana, Lagotis alutacea and Lagotis brachystachya by the established method. Methods: The similarity of HPLC fingerprints of L. integra and L. brevituba was low, so the HPLC fingerprint methods were established for both. The HPLC analysis was performed on Waters X-Bridge C18 (250 mm × 4.6 mm, 5 μm), using acetonitrile and 0.2% formic acid solution as the mobile phase at a flow rate of 1.0 mL/min, the detection wave-length was 328 nm and column temperature was 35 ℃ (L. integra) and 25 ℃ (L. brevituba). Results: There were 14 common peaks in the fingerprint of L. integra, and plantamajoside, hemiphroside B, 10-O-trans-p-methoxycinnamoyl-catalpol and 10-O-[(E)-3,4-dimethoxycinna moyl]-catalpol were standardized. There were 13 common peaks in the fingerprint of L. brevituba, and echinacoside, plantamajoside and acteoside were standardized. The similarity of HPLC fingerprint was more than 0.9 between L. integra and L. alutacea, but the others had low similarity with them. The similarity of HPLC fingerprint was more than 0.9 between L. brevituba from different batches and L. ramalana, while the others had low similarity with them. Conclusion: The established method could effectively identify L. brevituba, L. integra and L. alutacea were advised to be recorded in Medical Standards of the Ministry of Health. Lagotis ramalana could be used as a new base for "Honglian" (origin: Lagotis brevituba).

The clinical features of 17 patients with benign urachal masses and 30 patients with urachal carcinoma treated at Sun Yat-sen University Cancer Center were analyzed retrospectively.Univariate analysis indicated that seven parameters differed significantly between the two groups.Binary logistic regression analyses showed that the rate of gross hematuria was significantly higher (P =0.042,Exp[B] =7.889) and the rate of fatty infiltration of the Retzius space was significantly lower (P =0.006,Exp[B] =0.028) in patients with urachal carcinoma than in those with benign urachal masses.Gross hematuria and fatty infiltration of the Retzius space may be indications of malignant and benign urachal masses,respectively.

MAIN OUTCOME MEASURES: Free running EMG and stimulus triggered EMG, including time, frequency, amplitude, muscle group were observed and recorded simultaneously. Never root functional injury and restoration after surgery were detected.RESULTS: 378 pedicle screws in 74 patients were monitored intraoperatively, and only 3 pedicle screw malposition (2 of L_4, 1 of L_5) was detected and then replaced with the help of C-arm fluoroscopic examination. Myoelectricity appeared when the current intensity was less than 10 mA. The correct rate of implantation was 99.2%. Nerve root impingement was found in two cases during laminectomy for L_5 and S_1 decompression and never root solution, which alerted the surgical team of critical neural structures. Nerve symptoms of the lower limb were aggravated after surgery and restored following 2-4 weeks of conventional treatment. The error injury rate of nerve root was 2.7%. In all reported cases, no irreversible neurological deficit was observed 2-4 weeks after operation.CONCLUSION: Intraoperative EMG monitoring can find improperly placed screws and detect impending nerve root injury promptly. Combined EMG and 3-D imaging modality monitoring is a reliable and practicable method that can be used to protect neural structures during complex lumbosacral surgery.
