Objective To investigate the possibility of plastic and cosmetic operation incorporating epicanthoplasty with the double-eyelid procedure in one stage to achieve a more subtle scar in epicanthus patients with single eyelid. Methods After designing incision line of the epicanthic flap, double-eyelid line and the lower eyelid incision curved line, we cut the medial canthus skin transversely to reach a new medial canthus point, incised the part of front angle of medial palpebral ligamentum longitudinally and fixed the end point of front angle of medial palpebral ligamentum to nasal dorsum fascia firmly. Double eyelid operation was routinely performed to remove redundant small triangle skin as well as some patchy of orbicularis on the new medial canthus point. Along with eyelid edge about 1 to 2 mm to eyelash, the temporal side was cut with curved line till its disappearance by eyelid's "cat ear". The lower eyelid flap was separated downward and the superfluous flap and some patchy of orbicularis cut. The skin was su-tured to make postoperative scar hidden, blepharophimosis increased and the fold disappeared. Results 46 eyes (23 cases) were operated and satisfactory aesthetic results were obtained. Palpebral fissure was enlarged to 2 to 4 mm with epicanthic scar disappearance and formation of double-eyelid. Conclusions This is a simple and effective procedure with hidden epicanthic scar and the double-eyelid blepharoplasty could be performed simultaneously. Most patients receive satisfactory results during the 0.5 to 2 years' follow-up period except 2 cases with mild proliferation of epicanthus in half a year. It is especially suitable to correct the severe epicanthus palpebralis or epieanthus tarsalis.

Objective To observe the effect of effective monomer of Kangxianling prescription on renal function and extracellular matrix composition of 5/6 nephrectomy rats model, and provide basis for the screening of effective traditional Chinese medicine of anti-renal fibrosis. Methods Sixty SD rats were randomly divided into normal group, model group, chrysophanol group, salvianolate A group, oleanolic acid group and losartan group. The kidney fibrosis model was made by operation. Two months after intervented by correspong drugs, renal pathological changes of all groups were observed, the levels of renal function indexes were detected, and real-time PCR assay was used to detect laminin (LN), fibronectin (FN), type Ⅲ collagen (C-Ⅲ), type Ⅰ collagen (C-Ⅰ) mRNA expression in rat kidney tissue. Results SCr and BUN in model group increased significantly compared with the normal group (P<0.01). SCr and BUN in salvianolate A group decreased significantly compared with the model group (P<0.05, P<0.01). BUN in salvianolate A group decreased significantly compared with the losartan group (P<0.01). The expression of C- ,Ⅲ C-Ⅰand LN were reduced by effective monomer of Kangxianling prescription. Conclusion Effective monomer of Kangqianling prescription can inhibit renal fibrosis through reducing the expression of extracellular matrix components, thereby improve the renal function.

AIM: To investigate curative effects of excimer laser corneal refractive surgery for adults or older adolescent with hyperopic anisometropic amblyopia.METHODS: From March 2014 to March 2016, we selected 26 cases 26 eyes of adults or older adolescent with hyperopic anisometropic amblyopia in our hospital.All eyes underwent laser in situ keratomileusis, observed for the uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), diopter and stereopsis.RESULTS: At the end of the follow-up, the patient`s spherical equivalent and anisometropia were 1.47±0.51D and 1.15±0.22D, were significantly lower than that before operation (P<0.05).At the end of the follow-up, the distance and near UCVA and BCVA were 0.26±0.13 and 0.23±0.09, 0.42±0.09 and 0.31±0.16, which were significantly higher than those before operation (P<0.05).At the end of follow-up, the visual function of the patients was significantly improved (P<0.05), the rate of postoperative visual function < 100 eyes was 23%.CONCLUSION: In adult or older adolescent with hyperopic anisometropic amblyopia, excimer laser corneal refractive surgery has a certain effect.

Objective To explore the mutation and evolution of Yersiniapestis(Y. pestis) from the point of codon and 16S-ribosome. Methods Codon preference and 16S-ribosome of Y. pestis were analyzed by bioinformatics. Results Similar codon preference was found among 4 PCD1 Y. pestis, of the 3 old Y. pestis the codon preference between PMT1 and PCD1 was similar. There were some differences between PCD1, PCP1 and Yunnan 6 kb plasmid. Through the analysis of 16S-ribosome, the sequences were found similar in 11 strains of Y. pestis,Yersinia pseudotuberculosis was very close to Y. pestis, with only one nucleotide difference, mutated G-T, and corresponding amino acid methionine (M)-isoleucine (I). There were some differences in sequences of 16S-ribosome in Y. pestis, Escherichia coli and Pulex irritans. Conclusions The time for Y. pestis to obtain PCP1 is later than PMT1 does, in other words, the affinity of Y. pestis with PMT1 was closer than PCP1 with 6 kb plasmid;alteration of 16S-ribosomal nucleotide sites may cause changes in function and structure of 16S rRNA. The lower similarity between 16S-ribosomal sequences of Y. pestis and Pulex irritans indicates the time for co-evolution is very short,and the late emergence of Y. pestis.

A total of 128 TCM physicians completed the questionnaire, which was created according to Medical Care Guideline of Stroke Rehabilitation in China. Results Overall accuracy of stroke rehabilitation basic knowledge was 66.83%, 88.77% of stroke rehabilitation evaluation, 75.12% of stroke rehabilitation treatment. Conclusion The knowledge of stroke rehabilitation is insufficient among TCM physicians in tertiary A-level hospitals, and further training is needed.

Objective To evaluate the influence of narrow-band ultraviolet B on lesional microvessel density (MVD),vascular endothelial growth factor (VEGF),matrix metalloproteinases 2 (MMP-2)as well as on serum VEGF in patients with psoriasis vulgaris(PV).Methods Fifteen patients with PV were recruited into this study with 10 normal human controls.All patients received NB-UVB phototherapy thrice a week for 4-5 weeks.Prior and after the treatment,psoriasis area and severity index (PASI)was calculated,tissue specimens were taken from non-photoexposed lesions,and sera samples were obtained from these patients.Then,MvD and the expression level of VEGF and MMP-2 were measured by immunohistochemical labeled dextran polymer(LDP)method in the tissue specimens.Also,the serum level of VEGF was tested by enzyme-linked immunosorbent assay(ELISA).Results PASI score remarkably decreased in patients after the photothempy(t=13.35,P＜0.01).The MVDs were 20.52±5.02,7.33±1.24 and 4.26±0.79 capillaries per high power field(400 × amplification),in psoriatic lesions before treatment,after treatment,and normal control tissues,respectively,with a significant difference among the three groups (F=97.57,P＜0.05),and a significant increase was observed in the lesions before treatment compared with those after treatment and normal controls.The serum level of VEGF was 307.55±121.65 ng/L in psoriatic lesions before treatment,significantly higher than that after treatment(163.92±95.57 ng/L),and in normal control skin (139.78±79.06 ng/L),whereas there was no significant difference between the latter two groups(P＞0.05).The positivity rate of MMP-2 was similar among the three groups without statistical difference(P＞0.05).In psoriatic patients,a positive correlation was observed among PASI score,MVD,lesional and serum VEGF levels(P＜0.05),also among the MVD,VEGF and MMP-2 levels in lesions(P＜0.05).but lesional MMP-2 was unrelated to PASI score or sgrum VEGF(both P＞0.05).Conclusions NB-UVB may regulate superficial dermal microvascular proliferation by acting on the expression of VEGF in sera and lesions of psoriatic patients.VEGF and MMP-2 may bOth participate in the proliferation process of microvessels,while MMP-2 is unlikely to be involved in the therapeutic mechanism of NB-UVB.

Objective To investigate the value of intraoperative ultrasound in the resection of hemangioblastoma.Methods Intraoperative ultrasound was applied in 17 patients who underwent resection. The size,number,location ,depth,feeding arteries and draining veins of the tumors were clearly displayed.Results Intraoperative ultrasound could real-time locate the tumor with high accuracy. Totally there were 35 tumors in 17 patients, and intraoperative ultrasound found 32 of them.The diameter of thr smallest tumor was 7 mm. Intraoperative ultrasound could displayed clearly the feeding arteries and draining veins in bigger tumors. Conclusions Intraoperative ultrasound should be routinely used in the operation of hemangioblastoma for its high detection rate.

This study examined the dynamic characteristics of upper airway collapse at soft palate level in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS) by using dynamic 3-Dimensional (3-D) CT imaging. A total of 41 male patients who presented with 2 of the following symptoms, i.e., daytime sleepiness and fatigue, frequent snoring, and apnea with witness, were diagnosed as having OSAHS. They underwent full-night polysomnography and then dynamic 3-D CT imaging of the upper airway during quiet breathing and in Muller's maneuver. The soft palate length (SPL), the minimal cross-sectional area of the retropalatal region (mXSA-RP), and the vertical distance from the hard palate to the upper posterior part of the hyoid (hhL) were compared between the two breathing states. These parameters, together with hard palate length (HPL), were also compared between mild/moderate and severe OSAHS groups. Association of these parameters with the severity of OSAHS [as reflected by apnea hypopnea index (AHI) and the lowest saturation of blood oxygen (LSaO(2))] was examined. The results showed that 31 patients had severe OSAHS, and 10 mild/moderate OSAHS. All the patients had airway obstruction at soft palate level. mXSA-RP was significantly decreased and SPL remarkably increased during Muller's maneuver as compared with the quiet breathing state. There were no significant differences in these airway parameters (except the position of the hyoid bone) between severe and mild/moderate OSAHS groups. And no significant correlation between these airway parameters and the severity of OSAHS was found. The position of hyoid was lower in the severe OSAHS group than in the mild/moderate OSAHS group. The patients in group with body mass index (BMI)≥26 had higher collapse ratio of mXSA-RP, greater neck circumference and smaller mXSA-RP in the Muller's maneuver than those in group with BMI<26 (P<0.05 for all). It was concluded that dynamic 3-D CT imaging could dynamically show the upper airway changes at soft palate level in OSAHS patients. All the OSAHS patients had airway obstruction of various degrees at soft palate level. But no correlation was observed between the airway change at soft palate level and the severity of OSAHS. The patients in group with BMI≥26 were more likely to develop airway obstruction at soft palate level than those with BMI<26.
