OBJECTIVETo explore the correction for shortened and broaden prolabium deformity following bilateral cleft lip repair.

METHODSWe designed the upper lip double flag-shaped flaps. The quadrilateral original surgical scar (flap flag pole part) was resected and the incision was made along the direction of nasolabial groove at the nostrils bottom to form two flag-shaped flaps (the section of the flag face). Lip tubercle were tracted and blunt dissection of upper philtrum were performed to form a wound, 4-6 mm in width. The flag-shaped flaps on both sides were rotated to the central, in order to form a new nasal base and new prolabium, followed by V-Y or Z plasty procedure to correct the defect of tubercle and vermilion.

RESULTS10 cases were enrolled for the clinical application from January 2008 to December 2012. The height of the prolabium was lengthened by 4-6 mm after operation, which fundamentally corrected shortened and broaden prolabium deformity after bilateral cleft lip operation. The procedure can also correct the depression or defect of tubercle, too wide philtrum, philtrum column scar and the deformity of vermilion border continuity. The patients were followed up for a period of 3 months to 3 years with satisfactory results.

CONCLUSIONDouble flag-shaped flaps of the upper lip at the nostrils bottom is a simple and good surgery method to correct the shortened and broaden prolabium deformity following bilateral cleft lip repair.

AIMTo study the effect of Angelica sinsensis polysaccharides on lymphocyte proliferation and induction of IFN-gamma.

METHODSAngelica sinensis polysaccharides(AP) were separated into AP-I, AP-II, AP-III and AP-IV by alcohol deposition with different concentration. The radioactivities of [3H]-TdR uptake by lymphocyte were used to determine the ability of lymphocyte. The bioactivity of IFN-gamma was measured by violet crystalline dying.

RESULTSAP-IV was found to be composed of Ara and Glu in the ratio of 0.99:6.47, the molecular weight was estimated to be 5,600. AP-I and AP-II 100 mg.kg-1 i.p. were found to significantly augment mice splenocyte proliferation, release IFN-gamma and increase IFN-gamma bioactivity. 50 micrograms.mL-1 AP-I, AP-II and AP-III were shown to enhance the proliferative response of the mouse spleen lymphocytes in vitro.

CONCLUSIONAP-I and AP-II showed higher immunoactivity than AP-III, AP-IV had no effect.

Objective By analyzing mitochondrial function,reactive oxygen species (ROS) and adenosine triphosphate (ATP) production under different levels of RalA and caveolin-1 (Cav-1) expression,to investigate the regulation role of RalA played in cancer metabolism and explore the possibility of its regulation role involved in Cav-1 and caveolae motility.Methods Firstly,RalA and Cav-1 expression were inhibited by siRNA in breast cancer cell line MDA-MB-231,and then the changes of mitochondrial membrane potential (MMP),ROS produc tion,ATP generation and L-lactate level before and after inhibition were assessed by Western blotting,confocal microscope and fluorescence quantification.Results (1) The decreased RalA and Cav-1 expression led to a significant reduction of MMP directly.(2) Low RalA and Cav-1 expression resulted in an inhibition of ATP production and an increase of H2O2 generation.With the reduction of MMP,mitochondrial malfunction was observed.(3) With mitochondrial function suppression,an elevated level of glycolysis metabolite L-lactate was also detected in RalA and Cav-1 deprived cells.Conclusions RalA and Cav-1 mediate cellular metabolic switch by inhibiting mitochondrial function and simultaneously boosting glycolysis.This regulation role of RalA depends on its association with Cav-1,and possibly is related to the endocytosis and motility of caveolae.The research findings enrich the cancer metabolic studies,and provide a novel approach for cancer therapeutic strategy targeted to cellular metabolism.

Objective: This is a review of our cases and published literature on cheiro-oral syndrome (COS), to better understand its localization, etiology and outcome. Methods: In addition to our database, we reviewed the medical database (including PUBMED, BIOSIS, EMBASE, and SCOPUS) and other sources, searched by the keyword of “cheiro-oral”. The defi nition of COS was a subjective or an objective sensory disturbance confi ned to the perioral area and the fi nger(s)/hand without a detectable abnormality in mental, motor or cerebellar function. Only cases of COS where the clinicoanatomic correlation could be identifi ed by neuroimaging study, autopsy or stereotatic surgery was included. Results: There were a total of 174 patients; 85 patients from our database, 76 patients from medical database, and 13 patients from other sources. They were 111 men and 63 women. Their age ranged from 12 to 85 years; average being 58.2 years. Stroke is the leading etiology and constituted 74% of the patients. The most common location of lesion was thalamus, followed by pons and cortex. Classical unilateral COS was seen in 81% of patients, atypical COS in 19%. Whereas the lesions were from cortex to cervical spinal cord in unilateral COS, atypical COS was associated with lesions in pons or medulla oblongata. An early deterioration was seen in 16.5% of patients, especially in large cortical infarction and subdural hemorrhage. Structural lesions were found in 85% of patients. Conclusion: Classical unilateral COS do not have a high localizing value, the atypical COS is associated with lesion in pons or medulla.

OBJECTIVETo observe the therapeutic effect of head point-through-point therapy on insomnia and to probe the mechanism.

METHODSSeventy-one cases of insomnia were randomly divided into a head penetration needling group (n=36) and a routine acupuncture group (n=35). In the head penetration needling group, Shenting (GV 24)-through-anterior Shencong (EX-HN 1), bilateral Toulinqi (GB 15)-through-bilateral Shencong (EX-HN 1), posterior Shencong-through-Qiangjian (GV 18) were selected; and in the routine acupuncture group, Baihui (CV 20), Yintang (EX-HN 3), Sishencong (EX-HN 1), Neiguan (PC 6), etc. were selected. After treatment of 30 days, their therapeutic effects, cumulative scores of Pittsburgh Sleep Quality Index (PSQI) and plasma serotonin contents before and after treatment were compared. Results The total effective rate of 91.7% in the head penetration needling group was better than 77.1% in the routine acupuncture group (P < 0.05), and the improvement of sleep quality, falling asleep time and the total cumulative score of PSQI in the head penetration needling group was superior to that in the routine acupuncture group (P < 0.05), and plasma serotonin was significantly increased in the head penetration needling group with a significant difference as compared with that in the routine acupuncture group (P < 0.05).

CONCLUSIONThe therapeutic effect of head penetration needling is better than that of the routine acupuncture, and the mechanism is related with regulation of serotonin metabolism.
