With deep acupuncture at Baliao points (eight sacral foramina) as the core, Professor WANG Ling-ling has treated diseases of urinary, digestive and reproductive systems with superior therapeutic effect. The key for efficacy of Baliao points is deep acupuncture. Only deeply insert into acupoints with long needles and directly stimulate at sacral nerves, could Baliao points play a superior role in treatment effect. Searching acupoints is the basis of deep acupuncture, and superficial anatomy should be combined to summarize the methods of searching Baliao points. The premise of deep acupuncture is needling manipulation. The angles of needles must be adjusted according to morphological features of posterior sacral foramina, or it is hard to practice deep acupuncture into Baliao points. The description of location and manipulation on Baliao points in ancient and modern literature was vague, which restricts clinical application of Baliao points. A lot of research on location, manipulation and clinical application of Baliao points has performed by Professor WANG Ling-ling, and its manipulation and clinical cases are introduced to make a positive effect on its application and popularization.

Objective To study the effects of manganese on the expression of caspase-3 and cytochrome-c in the spermatogenic cells of rats. Methods Forty-eight male SD rats were randomly divided into the high dose,low dose exposure groups and the control groups,16 in each,were given manganese(MnCl2?4H2O) at 15,30 mg/kg and normal saline,I.P. once a day, 5 times a week,for 6 consecutive weeks. In the 4th and 6th weekend,the testis were collected,the expression of caspase-3 and cytochrome-c in the testis was determined by immunohistochemical methods (SABC). Results The caspase-3-positive-cell rate in the spermatogenic cells of rats in the high dose and low dose exposure groups increased significantly (P

OBJECTIVETo observe effects of mild moxibustion and lovastatin on immunologic function in rabbits with chronic hyperlipidaemia and atherosclerosis (AS) to initially explain regulating rules of mild moxibustion on immunologic function.

METHODSAmong thirty-two Japanese male big-ear rabbits, 8 rabbits were randomly selec ted as a blank group, the rest 24 rabbits were fed with method of endothelial injury and high-fat diet to establish AS model. The blank group was raised with normal diet and free water. After ten weeks of model establishment, the rest 24 rabbits were randomly divided into a model group, a moxibustion group and a medicine group, eight rabbits in each one. Moxibustion was applied at "Shenque" (CV 8) and "Zusanli" (ST 36) for 10 min per acupoint per day in the moxibustion group, while intragastric administration of 3.6 mg/kg lovastatin capsule was applied in the medicine group. After treatment, serum was acquired. Spectrophotometry method was adapted to measure cholesterol (TC) and high-density lipoprotein (HDL-C) and evaluated atherosclerosis index (AI), while enzyme-linked immunosorbent assay method was used to measure interferon-gamma (IFN-gamma) and interleukin-4 (IL-4).

RESULTS(1) The serum TC and HDL-C in the model group were significantly higher than those in the blank group, moxibustion group and medicine group (all P < 0.01). The mean value of AI was 1.683 +/- 0.486 in the moxibustion group, which was obviously lower than 20.301 +/- 4.022 in the model group (P < 0.01). (2) The ratio of Th1/Th2 was 0.569 +/- 0.143 in the moxibustion group and 0.445 +/- 0.079 in the medicine group, which were significantly lower than 0.917 +/- 0.255 in the model group (both P < 0.01), but there was no statistically significant difference between the moxibustion group and the medicine group (P > 0.05).

CONCLUSIONThe moxibustion for AS could reduce atherosclerosis index, influence drift and bias of helper T cell and regulate balance between humoral immunity and cellular immunity. As a result, status of relative balance of immunity is acquired, which could slow down the development of atherosclerosis and process of thrombus burst.

OBJECTIVETo study the antalgic and antiphlogistic functions and mechanism of ronggudingtong (RGDT) plaster (traditional Chinese medicine).

METHODSThe painful models were established with hot plate test or acetic acid writhing and the inflammatory models were established with daubing dimethylbenzene on auricle or injecting formaldehyde in toe or synovial envelope to study the antalgic and antiphlogistic functions of RGDT Plaster. The total protein and leukotriene B4(LTB4) in inflammatory exudate were detected to investigate the antalgic and antiphlogistic mechanism of RGDT plaster. The mice were randomly divided into different groups (n = 11), on the basis of drug using, the indexes of pain threshold, swelling degree were observed. Sixty-six mice were used to establish gasbag synovitis model and randomly divided into normal control group,model control group, positive control group (Voltaren gel 0.8 mg/d)and low/medium/high dosage RGDT plaster treating groups(30 mg/d, 60 mg/d, 120 mg/d).

RESULTS30 mg/d, 60 mg/d,120 mg/d RGDT plaster could upgrade the pain thresholds, remit auricular and foot swelling (P < 0.05, P < 0.01), and degrade total protein and LTB4 in inflammatory exudates (P < 0.05, P < 0.01).

CONCLUSIONRGDT plaster has some antalgic and antiphlogistic functions, and one of the mechanisms is depressing synthesis of LTB4.

Background Eyes with filamentary keratitis present with serious clinical symptoms.This disease is easy to relapse and the treatment is tricky.At present,its pathogenesis is still unclear,and few works were done on filamentous composition.Objective This study was to analyze the composition of corneal filament by imageological and histopathological method,and discuss the formation mechanism of filamentary keratitis.Methods Eighty-eight eyes of 82 cases who suffered from filamentary keratitis were collected in Shandong Eye Hospital between January 2008 and January 2011.The etiologies of the patients were classified and the clinical data were recorded.Firstly,the corneal filiform strip was detected by laser scanning confocal microscopy (LSCM),and the corneal structure was examined by high-definition optical coherence tomography (HD-OCT).Then the composition of filamentary strip was analyzed by Giemsa and Masson trichrome staining of stretched preparation of filiform strip.Results Etiological study showed that filamentary keratitis occurred after penetrating keratoplasty in 40 eyes,after cataract surgery and photorefractive keratectomy (PRK) in 18 eyes,dry eye and neural dystrophic corneal disease in 14 eyes,acute conjunctivitis in 10 eyes.HD-OCT revealed that filament lesion developed to Bowman layer.Filament was composed of epithelial cells,inflammatory cells,mucus and the high reflective strip core with spiral arrangement under the LSCM,and epithelial cells,inflammatory cells and fibrous tissue were seen in the strip core.Giemsa staining exhibited that filament contained corneal epithelial cells,inflammatory cells,mucus and dark blued strip core with helical arrangement.Masson trichrome discovered that the strip core was red fibrous tissue surrounding by blue mucus.Conclusions Epithelial cells,inflammatory cells,mucus and the high reflective strip core with spiral arrangement are the main elements of filament in filamentary keratitis.The lesion can reach Bowman layer.The results contribute to reveal the formation mechanism of corneal filament and assist treatment.

Objective To investigate the relationship between epigenetic changes involving multiple modifications of histones and both happening of glioma and pathological grades of glioma.Methods Immunohistochemistry was performed on 67 samples that were cut off from patients with gliomas who made their definite diagnosis from 2006 to 2008 to evaluate the level of histone 4 lysine 12 acetylation (H4K12Ac), histone 4 arginine 3 monomethylation (H4R3monoMe) and histone 4 lysine 20 acetylation (H3K18Ac). Results H4K12Ac, H4R3monoMe and H4K20triMe were all detected at high frequencies in tumor tissue of glioma. The expressions of H4K12Ac and H4R3monoMe were positively correlated with increasing WHO pathological grades (P＜0.05), while H4K20triMe staining was not significantly correlated with WHO pathological grades (P＞0.05). Conclusion Multiple modifications of histones may affect several steps in tumor cell biology, and may have a prognostic value in gliomas since specific modifications were correlated with WHO pathological grades of glioma.
