Objective To study the surgical repair mode of skin cancer in facies in aged patients. Methods The modes of surgical repair in 216 cases of aged patients with skin cancer in facies were analyzed. Results The special characteristics of physiology and pathology and the facies anatomy in the elderly determined the complexity of surgical repair. The surgical mode of excision and suture was the safest and the most efficacious. Skin flap transfer could mostly satisfy the function requirements of facies for the wound that was not able to be sutured after excision. Free skingrafting was applicable to the case that the deep tissue was not invaded by the tumor and the general condition of the patients was not much good. Conclusion The order of surgical repair modes for skin cancer in the facies in the elderly is excision and suture, skin flap transfer, and free skingrafting. Local skin flap must be the primary source as the selection of the skin flap is concerned. The suitable axial pattern skin flap or musculo-cutaneous flap can be selected according to the different section of the facies while there is no suitable local tissue.

Objective To analyze proliferating cell nuclear antigen(PCNA) index in invasive, proliferative,aged parts of keloid to explore the mechanism of keloid invasive growth characteristics. Methods PCNA in 10 cases of keloid and 10 cases of normal skin was detected by immunohistochemical staining, and the PCNA index of different parts in keloid and normal skin was compared. Results The PCNA index of invasive part in keloid was obviously higher than that of proliferative,aged parts of keloid and normal skin (P

Objective To explore the effect of tonifying kidney with traditional Chinese medicine together with estradiol valerate and clomiphene citrate on serum leptin levels in patients with polycystic ovarian syndrome. Method Two hundred and eight patients with PCOS were randomly divided into observation group (n=104) and control group (n=104). Patients in control group and observation group took estradiol valerate and clomiphene citrate, while patients in observation group took Shiying Minlin soup for three months. Crinosity, body temperature, acne&Skin diseases, and menoxenia were recorded; Leptin (LP) and five hormone including follicle stimulating hormone (FSH),luteinizing hormone (LH), prolactin (PRL), estradiol (E 2) and testosterone (T) are determined using euzymelinked immunosorbent assay. Results Crinosity, body temperature, acne&Skin diseases, and menoxenia were improved;the level of FSH, LH, PRL, E 2, T in both observation and control group decreased and the content in observation group are high than that in control group, while LH,T and E 2 are lower. Conclusion Treatment with tonifying kidney with traditional Chinese medicine on polycystic ovarian syndrome can decrease the level of FSH, LH, PRL, E 2, T and LP. Compared with western medicine, tonifying kidney with traditional Chinese medicine showed advantage in the terms of treatment on polycystic ovarian syndrome.

Objective To observe the effects of pentifylline on hypertrophic scars in the rabbit ears. Methods An animal model for hypertrophic scars was established and treated with pentifylline in different concentrations or saline on day 49. Hypertrophic index, growth of fibroblasts and production of collagen in the section were quantitatively determined with an image analysis system. Results Hypertrophic index was found to be decreased in the pentifylline-treated group (P

Objective Nonsyndromic cleft lip with or without cleft palate(NSCL/P)is a common craniofacial birth defect which results in lifelong medical and social consequences.Although Asians have the highest birth prevalence of oral-facial clefts,the majority of gene mapping studies of cleft lip with or without cleft palate(CL/P)have been in European or Ameriean Caucasians.Therefore,the obiective of this study was to evaluate association between transforming growth factor alpha(TGF-α)gene BamH Ⅰ polymorphism and NSCL/P in Chinese.Methods 107 patients with NSCL/P and 136 healthy controls were examined for TGF-α/BamH Ⅰ genotypes.TGF-α/BamH Ⅰ typing was carried out by digesting the locus specific polymerase chain reaction amplified products with alleles specific BamH Ⅰ restriction enzyme(PCR-RELP).Resuits A1 allele frequency was 0.06 and A2 allele frequency was 0.94 in the controls.A1 allele frequency was 0.14 and A2 allele frequency was 0.86 in patients with NSCL/P(x2=8.27,df=1,P＜0.05).A1 allele frequency was 0.17 and A2 allele frequency was 0.83 in the bilateral cleft lip with or without cleft palate.A1 allele frequency was 0.13 and A2 allele frequency was 0.87 in the unilateral cleft lip with or without cleft palate(x2=0.36,df=1,P＞0.05).There was no statistically significant between the case with family history and the case without family history(x2=0.34,df=1,P＞0.05).Conclusions The above data demonstrate that there is evidence for the association of TGF-α polymorphism with development of NSCL/P in Chinese.

BACKGROUND: Clinical genetics and molecular biology studies have shown that the occurrence and development of the keloid is closely related to the inheritance. However, it remians unclear if the same is ture to the hypertrophic scar. OBJECTIVE: To investigate similadties and differences of genetic alteration between the hyperplastic scar and the keloid, DESIGN, TIME AND SETTING: A contrast observational experiment was performed in Guangdong Medical College between March 2007 and December 2008.MATERIALS: Scar samples were taken from 16 patients (in-patient and out-patient) in the Department of Plastic Surgery, the Affiliated Hospital of Guangdong Medical College, with10 patients with hypertrophic scars (3 males and 7 females, 20-50 years old) and 6 patients with keloids (1 males and 5 females, 19-46 years old). METHODS: The DNA of both hyperplastic scar and keloid tissues was extracted to investigate, using comparative genomic hybridization technique, the genomic imbalance (the lose or amplification of genetic material), so as to make a comparative study on differences of the DNA copy number changes between the two. RESULTS: Neither altofrequent loss nor amplification of DNA copy number was found in any specific DNA region of hyperplastic scar tissues; as for the keloid, special DNA altofrequent loss regions were also not found, but altofrequent DNA copy number loss regions presented in 1, 16, 20 and 22 chromosomes. Comparatively, the keloid presented much higher loss rate of the DNA copy number in 1,16,20 and 22 chromosomes than the hyperplastic scar (P < 0.05).CONCLUSION: The hyperplastic scar has no conspicuous DNA copy number lose or amplification compared with the keloid, which indicates that the occurrence and development of the hyperplastic scar may not have any direct relation with the inheritance.

OBJECTIVETo summarize the therapeutic experience in removing huge craniofacial hemangioma in 135 cases and reveal the rules of repairing the damaged tissues or organs caused by the extirpation.

METHODSThe procedure was to remove the focal lesion correctly, control hemorrhage, keep the stable blood volume, repair and rebuild the damaged tissues or organs reasonably.

RESULTSThe focal lesion was removed rather completely without accidental injuries or deaths. The damaged tissues or organs were repaired and rebuilt quite satisfactorily.

CONCLUSIONHuge craniofacial hemangioma of any type should be operated on as early as possible with sufficient preoperative preparations.

Carotid endarterectomy (CEA) is one of the methods to prevent stroke in patients with atherosclerotic carotid stenosis. Under cervical plexus block, the consciousness of patients can be evaluated to determine whether shunt is needed during the clamp period of carotid artery. Traditional nerve block adopts blind technique according to anatomical landmark. Ultrasound-guided nerve block can identify accurate location of puncture site, improve anesthesia effect and minimize the potential risk of block-related complications. To provide guidance for clinical application, this article reviews the status quo of carotid endarterectomy, anesthesia methods and ultrasound-guided cervical plexus block.
