To investigate the function of the acupoints of the stomach meridian in the treatment of obesity of gastrointestinal excessive heat. Methods: Fifty-one cases of the patients with obesity of gastrointestinal excessive heat were randomly allocated into two groups.The acupoints of the stomach meridian were mainly selected for the treatment group (A), and the combination of Back-Shu and Front-Mu points were used for the control group (B). The treatment was given once every other day, with one month as a course, 3 courses in total, to observe the changes in the symptoms and signs of the patients and to determine the obesity index before and after treatments and the experimental indexes such as leptin, blood lipids,blood sugar and ACHE. Results: In comparison of the control group, various obesity indexes could be significantly reduced (P＜0.01), hyperleptinemia and fat metabolic disturbance could significantly improved (both P＜0.05) and the imbalance status of the parasympathetic hyperfunction could be significantly reversed (P＜0.05) in the patients with obesity in the treatment group. Conclusion: The stomach-meridian acupoints can function on many rings in the occurrence and development of obesity and are key and effective acupoints for obesity of gastrointestinal excessive heat.

[ Objective ] To observe the effects of acupuncture in treating extraweight rats and on morphology of brown adipocytes. [ Methods ] Sixty SD rats were randomized into normal group ( group A), model group ( group B) and acupuncture group (group C). Group A was fed with common forage and groups B and C with high-fat diet for 12 weeks. After then group C was given acupuncture of Zusanli (ST36) and Neiting (ST44) points for 15 days. Body weight, body length and Lee's index were compared before and after treatment in the three groups; wet weight of perirenal fat was detected and the ultrastructure of interscapular brown adipose tissue was observed under transmission electron microscope after treatment. [Results] After treatment, body weight, Lee's index and wet weight of perirenal fat were decreased in group C (P

This study was aimed to evaluate the clinical effect of 66 yin-deficiency acne cases treated with body constitution adjustment using acupuncture and moxibustion. In this research, 66 acne patients with the body con-stitution of yin-deficiency were selected . These patients were randomly divided into two groups ( 33 every group ) . The acupuncture treatment group was treated by acupuncture and local treatment. And moxibustion treatment group was treated by indirect moxibustion and local treatment. The treatment was given twice a week. And the improvement condition of acne skin lesions and yin-deficiency body constitution were evaluated after 12-week treatment. The results showed that certain curative effects were received in both groups. However, the moxibustion treatment group had higher curative effect compared with the acupuncture treatment group. There were significant statistical differences between two groups ( P < 0 . 05 ) , which meant moxibustion with local treatment had a higher curative effect than acupuncture with local treatment to acne. In the aspect of skin lesion improvement, according to the statistics, the moxibustion treatment group were statistically significant compared with acupuncture group (P< 0.05), which meant more obvious improvement of skin in the moxibustion treatment group. In the aspect of body constitution, the body constitution scores in both groups were significantly declined and the moxibustion treatment group was more obvious. There was statistical significance between two groups (P < 0.05), which meant patients in the moxibustion treatment group obtained a more obvious body constitution improvement. After the treatment, follow-up was given to all patients for 4 weeks. The results showed that both the acne skin lesion con-dition and yin-deficiency body constitution score were decreased and not achieve the recurrence diagnostic stan-dard. It showed that acupuncture and moxibustion are able to activate the self-regulation and disease resistibility of the body. It was concluded that acupuncture and moxibustion not only improve skin lesion of acne patients with the body constitution of yin-deficiency with inner heat , but also regulate yin-deficiency body constitution . Moxibustion had higher efficacy in the treatment of yin-deficiency with inner heat acne than acupuncture.

Objective To investigate the value of panel fluorescence in situ hybridization (panel FISH)for detection of genomic aberrations in chronic lymphocytic leukemia(CLL). Methods Five types of fluorescein-labelled DNA probes including five sequence specific probes D13S25 for 13q14. 3, RB1, p53, ATM (11 q23)and centromeric probe for chromosome (CSP12) were used to perform fluorescence in situ hybridization assays in 17 patients with CLL. Its results were compared with that obtain by conventional cytogenetic (CC)examination. Results In 17 patients with CLL, CC examination showed that only one case (1/17) was found to have chromosomal abnormality that was simultaneous trisomies 3,8 and 18, whereas panel FISH assay showed that 10 cases (10/17) were found to have genomic aberrations including deletion of D13S25 in 4 cases,deletion of ATM in 2 cases,deletion of p53 in 1 case,deletion of D13S25 combined RB1 in 1 case and 1 case with a variety of abnormalities. Conclusions Panel FISH is a useful method for detection of genomic aberration in CLL If it is combined with CC,it can obviously enhance the detection rate of chromosomal abnormalities in CLL.

OBJECTIVETo assess the accuracy of ultrasound-guided 16G and 18G core needle biopsy for detecting ultrasound visible breast lesions with different sonographic features.

METHODSA total of 955 sonographically detected breast lesions examined with ultrasound-guided core needle biopsy (US-CNB) and subsequently surgically excised from July 2005 to July 2012 were retrospectively reviewed. Histological findings of US-CNB and the surgical specimens were analyzed for agreements, sensitivities, false negative rates, and underestimate rates according to different sonographic features.

RESULTSThe pathological results of the US-CNB showed malignant lesions in 84.1%, high-risk lesions in 8.4%, and benign lesions in 7.5% of the samples. The overall agreement rates were 92.4% for 16G CNB and 92.8% for 18G CNB; their complete sensitivities and false negative rates were both 98.6% and 1.4%, respectively; the high-risk underestimate rates and DCIS underestimate rates were 48.0% and 46.2% for 16G CNB vs 53.3% and 41.2% for 18G CNB, showing no significant difference between the two groups (P>0.01). For both 16G and 18G CNB, the agreements were better for mass lesions than for non-mass lesions (P<0.01). For the mass lesions with a diameter no greater than 10 mm, the agreement rates were lower than the overall data (P<0.01). Calcification in the lesions did not affect the agreement rates (P>0.01).

CONCLUSIONUltrasound-guided 16G and 18G CNB are both accurate methods for evaluating ultrasound visible breast mass lesions with a diameter larger than 10 mm.

Objective:To investigate the clinical and genetic characteristics of cerebellar ataxia, neuropathy, vestibular areflexia syndrome (CANVAS) with replication factor C subunit 1 (RFC1) gene mutation to improve the understanding of this disease.Methods:A case of CANVAS diagnosed in the Peking University Third Hospital in January 2021 was reported. Detailed genetic analyses of ataxia were performed with DNA extracted from the peripheral blood of the patient. Studies including pathogenic variants of RFC1 gene causing CANVAS were reviewed and the clinical and genetic characteristics of the disease were summarized.Results:The patient was a 51-year-old female with the prominent manifestation of progressive walking instability. And the clinical data met the diagnostic criteria of CANVAS. The genetic tests excluded other hereditary ataxia mutations and identified the biallelic expansion of the pathogenic variant structure (AAGGG)exp repeat amplification in RFC1 gene. A total of 14 studies on CANVAS with RFC1 gene mutation were reviewed. The overall mutation rate of RFC1 gene in CANVAS was 68%-100%, and it varied in sporadic and familial CANVAS. And the mutation had ethnic differences.Conclusions:Among adult patients with late-onset ataxia, the combination of brain magnetic resonance imaging, electrophysiology tests and vestibular function examination is beneficial to the identification of CANVAS. And the genetic test of RFC1 gene has significant value in the diagnosis of this disease. This patient with CANVAS expands the disease spectrum of ataxia in China, and confirms that RFC1 gene mutation is of great significance in the screening of ataxia disorders in the Chinese population.

OBJECTIVETo establish the theories and methods to determine apparent solubility paraneters of multiple components for the Chinese materia medica (CMM) with HPLC fingerprint.

METHODThe mathematical functional expresses to determine the apparent solubility parameters for multiple constituents were established according to total quantum geometrical average retention time (TQGART) for HPLC fingerprint that characterized the entirety tendencies for all-over chromatographic peaks, validated by the aloe-emodin's solubility parameters which had been determined. The HPLC for the aloe-emodin's solubility parameters were carried out with an Alltech Apollo C18 as column, Acetone: Water as mobile phase, gradient elution,flow rate as 1.0 mL x min(-1), the detection wave-length as 430 nm and the temperature as 30 degrees C.

RESULTThe mathematical functional model between the TQGART of HPLC chromatographic fingerprint and the total quantum apparent solubility parameters was established and used to determine the aloe-emodin's mixture solubility parameter as 36.12 J(1/2) x cm(-3/2), nearly equal to 35.57, 36.07 J(1/2) x cm(-3/2) calculated by ration of peak area ratios and molecular fraction, respectively.

CONCLUSIONThe TQGART of HPLC fingerprint can be used to determine simultaneously the apparent or single intrinsic solubility parameters for total quantum or intrinsic solubility parameters for single in multiple constitute systems, by which theoretical and technologic platform to study the compatibility rule and dosage form reform of the single CMM will be established.

Objective: To study the anti-inflammatory effect and mechanism of Gutong plasters in acute inflammatory model of rats. Methods:Totally 60 SD rats were randomly divided into the blank group,the model group,Gutong plasters at low,medium and high dose groups(0.594,1.188 and 2.376 g/patch containing crude drug 0.48,0.96 and 1.92 g,respectively) and prednisone ace-tate group(0.005 4 g·kg-1). The acute inflammation model was prepared by injecting 5% formaldehyde into right side of foot plan-tar. And then,the anti-inflammatory effect was evaluated by measuring the foot plantar volume. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of nitric oxide(NO),histamine(HIS) and 5-hydroxytryptamine(5-HT) in serum and inflam-matory tissue,the levels of prostaglandin E2(PGE2),tumor necrosis factor alpha(TNF-α),interleukin 1 beta(IL-1β) and interleu-kin 6 (IL-6) in inflammatory tissue were also determined. Pathological changes were observed through the pathological sections pre-pared by HE staining. Results:When compared with the model group,Gutong plasters could significantly inhibit the swelling of foot plantar in inflammatory rats(P<0.01). At the same time,Gutong plasters could significantly reduce the levels of NO,5-HT and HIS in serum and inflammatory tissue in different degrees(P<0.05 or P<0.01),significantly reduce the content of PGE2in inflammatory tissue (P<0.05 or P<0.01),increase the content of IL-6 in inflammatory tissue and improve the pathological changes of inflammato-ry tissues (the pathological score was significantly reduced). In partical indictor changes,Gutong plasters and prednisone acetate showed an equal effect.In addition,Gutong plasters didn't show significant dose-dependent manner in inhibiting foot swelling,affect-ing inflammatory mediators and improving pathological changes(P>0.05). Conclusion:Gutong plasters have better anti-inflammato-ry effect in the acute inflammation model induced by formaldehyde in rats. The anti-inflammatory effect may be associated with the de-crease of the levels of NO,5-HT and HIS in serum and inflammatory tissue,the decrease of the content of PGE2and the increase of the content of IL-6 in inflammatory tissue. In addition,the anti-inflammatory effect may be relevant to improving the local inflammatory tis-sue subcutaneous edema and inflammatory cell infiltration.
