Objective:To assess the clinical outcome of autologous fat injection in treatment of hemifacial atrophy,so as to search for an ideal treatment of hemifacial atrophy.Methods: Autologous fat granules were obtained by tumescent liposuction.After purification,the fat granules were injected in a multi-strata,multi-tunnel,and multi-spot manner to repair facial introcession abnormality.Patients whose introcession was not improved after the stabilization of the fillings were re-injected with autologous fat granules twice or more until satisfactory outcomes were achieved.Results: All the 7 patients in this study obtained satisfactory outcomes after fat injection and basically reached symmetry.The follow-up result was good after 2 years.Conclusion: Local injection transplantation of autologous fat granules is effective for the treatment of facial depression and hemifacial atrophy,with slight trauma,little complication,and satisfactory outcome.

Objective:To investigate the anatomic characteristics of the pudendal-thigh flap and provide anatomic basis for clinical design and application. Methods: The perineal regions of 15 male cadavers were anatomized. The flap was designed on the cadavers and the blood vessels/nerves contained in the flap were studied. Based on the above anatomic findings, we designed the flaps in our operation. The axial arteries were isolated according to the designing and the tissue adjacent to the vessel pedicles was preserved. The flaps were transferred to the recipient site. The incision of donor site was directly sutured; skin graft was transplanted when the incision could not be directly sutured. Results: The perineal regions had rich and constant blood supply and had stable nerve innervation. The blood supplies of the perineal region included external pudendal artery, anterior cutaneous branches of obturator artery, lateral branch of posterior labial or scrotum arteries. The location of the above vessels was comparatively constant, especially external pudendal arteries and posterior scrotum arteries. Three groups of blood vessels went through the lower, middle and upper parts, and there were 4 groups of major nerves responsible for the innervation of the pudendal region. We have used 23 cases of pudenal-thigh flaps, with the largest flap being 17 cm X 9 cm and the smallest being 8 cm X 5 cm, and satisfactory outcomes were achieved in all the cases. Conclusion: The pudenal thigh flap has rich blood supply, convenient incision, and covert donor site. It has satisfactory outcome (morphologic and sensory) in repairing and reconstructing male perineal region and is worth popularizing.

OBJECTIVE To evaluate distribution and resistance of pathogens in patients with pulmonary infection after abdominal operation by stages,and provide reference to select antibiotics in clinics.METHODS Forty five patients with pulmonary infection after abdominal operation were included from Jan 2004 to Sep 2007.Their course was divided into 3 stages: onset stage,middle stage and last stage,at every stage to identify pathogens and to test drug sensitivity and the sputa and broncho-alveolar lavage fluid(BALF) were sampled.RESULTS A total of 189 strains of pathogens were isolated,from them 110(58.2%)were Gram-negative bacilli including Pseudomonas aeruginosa,Escherichia coli and Klebsiella pneumoniae;and 59(31.2%)were Gram-positive cocci including Staphylococcus aureus and Enterococcus;and 20(10.6%)were fungi,Candida albicans was the main fungus.At onset stage the most pathogens were Gram-negative bacilli;at middle stage the Gram-positive cocci increased distinctly;and the fungi were detected at middle and last stages.The mixed infection rate was high.The result of drug sensitive test showed that there were high rates of multidrug resistance in P.aeruginosa.The resistance rates of all isolates of Enterobacteriaceae to imipenem or meropenem were 0.The resistance rates of all Gram-positive cocci to linezolid or vancomycin were 0.CONCLUSIONS Distribution of pathogens in patients with pulmonary infection after abdominal operation is different at each stage.The most are multidrug resistant,and rationl use of antibacterial drug in clinics must be based on the distribution and drug-resistance of pathogens.

Objective:To investigate the distribution of precancerous conditions and lesions of high-risk population in the high-in-cidence area of esophageal cancer in Ci County, Hebei Province. Methods:Esophageal cancer was detected early in 40 to 69 year old patients in Ci Xian through endoscopic screening data and endoscopic screening using iodine staining and indicative biopsy. The pa-tients were classified according to gender, age group, statistical esophageal precancerous condition, and lesion detection rate. Results:The analysis included 11 423 cases by screening queue, and the esophageal biopsy rate was 66.90%. The detection rates of squamous epithelium with mild, moderate, and severe dysplasia were 11.84%, 2.66%, and 1.04%, respectively. DCIS detection rate was 0.40%in patients with squamous cell carcinoma. The detection rate of the patients had been infiltrated by the squamous cell carcinoma was 0.04%.The rate of the squamous cell carcinoma within the mucosa was 0.37%.The rate of the infiltration squamous cell carcinoma was 0.17%. The detection rate of the hyperplasia above average severe dysplasia and cancer was 2.01%. Conclusion: High incidence of esophageal precancerous lesions was found in the Ci County aged 40 to 69. A large number of asymptomatic patients with cancer were detected. Age and sex are closely related to detection rate.

AIM: To investigate the effects of advanced glycation end products (AGEs) on protein and mRNA expression of macrophage inflammatory protein-1? (MIP-1?) in cultured human umbilical vein endothelial cells(HUVECs). METHODS: HUVECs were cultured with AGEs at different concentrations for 24 h and at a concentration of 400 mg/L for different time.The levels of mRNA and protein expression of MIP-1? in cultured HUVEC were detected by in situ hybridization and Western blot, respectively. RESULTS: In situ hybridization showed that after exposure of HUVECs to AGEs at different concentrations (100 mg/L, 200 mg/L, 400 mg/L) for 24 h, the average integrated optical density values (18.76?3.17, 26.58?1.61, 34.23?2.25) of MIP-1? mRNA expression in HUVECs were higher than that in control group (13.83?1.24, P

Objective: Epithelial dysplasia of the esophagus and gastric cardia is precancerous lesion, including mild, moderate and severe levels. In 2000 year, WHO recommended to replace dysplasia with intraepithelial neoplasia. Mild and moderate dysplasia were classified as low-grade intraepithelial neoplasia (LIN). Cardia adenocarcinoma was suggested to be called esophageal-gastric junction adenocarcinoma. The risk of cancer development and the rule of time evolution were detected in esophagus and esophageal-gastdc junction LIN in high incidence area of esophageal cancer in Northern China, in an effort to provide scientific data for the prevention of esophageal cancer. Methods: Between October 2001 and October 2002, two townships of Cixian were chosen to carry out endoscopic iodine staining screening cohort study. The total population aged 0-85 was 22,016, of which 6,596 aged 40-69 (3257 males and 3339 females). Except for thoese with contraindications and those who refused to join the study, 3,506 cases were finally recruited in the study, and the screening rate was 53.2%. According to WHO criteria of the pathological diagnosis, the esophageal squamous epithelium with mild and moderate dysplasia and esophageal-gastric junction with mild dysplasia were classified into LIN groups (including 616 cases). The control group contained a total of 2,478 cases without precancerous lesions and free of cancer in endoscopic screening. Results: From June to September in 2008, the cohort was followed up and 174 cases were lost, with a follow-up rate of 95.0%. Follow-up was 3,970.7 person- years in the LIN group and 16,120.0 person-years in the control group.Carcinomous conversion rates were 251.7 and 68.2/per 100,000 person- years respectively in the LIN group and the control group. The median time in the two groups was 38 and 47 months, respectively. Compared with that of the normal population, the relative risk (RR) of LIN was 3.69 (95% CI=1.57-8.69, P=0.001). Conclusion: Population with LIN are at high-risk for esophageal cancer and endoscopic examination every year is absolutely necessary.

Objective To perform mutation analysis of survival motor neuron gene 1 (SMN1 in two spinal muscular atrophy (SMA) patients and their parents to evaluate the effects of the two SMN1 gene mutations on the transcript levels of the gene and preliminarily predict their effects on the structure and function of SMN protein.Methods Mutation analysis of SMN1 gene was carried out by multiplex ligationdependent probe amplification,reverse transcript-polymerase chain reaction (RT-PCR) and cloning sequencing.Transmission of the mutations was confirmed by the mutation analysis in patients' parents.The full-length SMN1 (SMN1-fl) transcript levels of the patients carrying these subtle mutations were detected using quantitative RT-PCR.Results The two patients were diagnosed as SMA Ⅱ and SMA Ⅲ.They carried p.Val19GlyfsX21 and p.Ala2Gly SMN1 mutations in SMN1 gene,respectively.Both of the two mutations were originated from their fathers.Compared with the healthy individuals (23.5 ± 4.9),the two patients had a significant reduction in the level of SMN1-fl transcripts (t =3.322,P =0.011 (p.Ala2Gly) ;t =6.964,P =0.000 (p.Val19GlyfsX21)).However,compared with the healthy carriers (14.1 ±4.5),the patient with p.Ala2Gly mutation had no significant reduction in the level of SMN1-fl transcripts (13.9 ±3.6,t =0.058,P =0.955) ; however,the patient with p.Val19GlyfsX21 mutation had a significant reduction (4.9± 2.4,t =3.725,P =0.004).Conclusions Two SMN1 gene mutations are identified in our study.The mutation p.Val19GlyfsX21 is a novel mutation and p.Ala2Gly is firstly reported in Chinese SMA patients.p.Val19GlyfsX21 may possibly lead to decreased SMN1-fl mRNA by nonsense-mediated messenger RNA decay,however,p.Ala2Gly has no obvious effects on the amount of the SMN1-fl transcripts,indicating that its deleterious effect may be occurring at SMN protein level or the function of SMN protein.

Objective To analyze the distribution of common chromosomal karyotypes of patients with Turner syndrome (TS), and to explore the correlation between the age and height standard deviation scores (HSDS) on diagnosis.Methods Retrospective investigation was performed for the data of age and HSDS on diagnosis in 273 TS girls(≤ 18.0 years old)diagnosed by chromosomal karyotypes.The main statistical methods were analyzed with t-test and Pearson correlation test by using the SPSS 18.0 statistical software.Results (1) There were 4 kinds of common chromosomal karyotypes in the TS :45, X (87/273 cases,31.9％),46, X, i (Xq) (43/273 cases, 15.7％) ,45, X/46, X, i (Xq) (36/273 cases, 13.2％) and 45, X/46, XX (23/273 cases, 8.4％), respectively, the adolescent TS all had delayed puberty.For the cases with 45, X karyotypes ,3 cases presented mental retardation and 2 cases with organs deformity.(2)The patients with 45 ,X/46,X,i(Xq) karyotypes or with 46,X,i(Xq) karyotypes had the maximum(12.56 age) or the minimum(9.70 age) mean age on diagnosis, respectively, there was a significant difference between 2 groups (t =3.019, P =0.004).The maximum deviation from normal height was found in the patients with karyotypes of 46, X,i (Xq) (HSDS =-4.04), and the minimum deviation was in the patients with karyotypes of 45,X/46, XX (HSDS =-3.16), and there was a significant difference between 2 groups (t =-2.95, P =0.004).(3) More than 75.7％ of TS patients was diagnosed when their heights deviated above 3 SD,and their mean age on diagnosis was 12.10 age,which was 3 years later than those patients within 2 SD.(4) There was a significant negative correlation between the age and HSDS on diagnosis in the groups of common chromosomal karyotypes[45,X、46,X,i(Xq) and 45,X/46,XX] (r =-0.551,-0.560,-0.622,all P ＜ 0.01), except for the group with the 45, X/46, X, i (Xq).Conclusions (1) In this study, the consti-tuent ratios of these 4 common chromosomal karyotypes were different from those in Europe and America's.(2)Patients with 45 ,X may have more severe symptoms than others.(3)The mean age on diagnosis was at least 3.0 years earlier when considered HSDS below-2.00 as an indicator for chromosomal karyotype screening,which would facilitate earlier diagnosis.

· AIM: To compare the measurement of anterior chamber depth (ACD) and axial length (AL) by IOLMaster and contact ultrasonic (US) axial scan (A-scan).· METHODS: Measurements of ACD and AL were prospectively obtained in 137 eyes of 121 subjects with the IOLMaster compared with measurements with the US.· RESULTS: There was an excellent correlation between IOLMaster and US measurements for the ACD (r=0.823;P＜0.001) and AL (r=0.996;P＜0.001). The mean values of the parameters measured by IOLMaster and US were,respectively, as follows: ACD, 2.94±0.49mm, 2.58±0.51mm;AL, 24.37±3.04mm, 23.81±2.83mm. The mean differences of ACD and AL values between IOLMaster and US measurements were 0.36 ±0.30mm, 0.56 ±0.34 mm respectively, and they proved to be statistically significant (P＜0.001), With the 95%limits of agreement (LoA) from -0.08mm to +0.38mm for ACD and from -0.09mm to +0.69mm for AL.· CONCLUSION: As noncontact biometry, IOLMaster provides accurate values. A high degree of agreement between US and IOLMaster was noted. It not only has the advantage of performing noncontact examinations, but also produces various additional data simultaneously and may thus obviate the need for multiple examinations. Further studies are needed to assess the interchangeability of measurements in clinical practice.

OBJECTIVETo compare the efficacy of different points combination in the treatment of menopausal insomnia.

METHODSNinety-six cases of menopausal insomnia were randomized into 3 groups, Xinshu (BL 15), Shenshu (BL 23), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6) were chosen in the restore interaction between the heart and the kidney group (group A, 32 cases); Zhaohai (KI 6), Jiaoxin (KI 8), Shenmai (BL 62), Pucan (BL 61) were chosen in the acupuncturing qiao mai group (group B, 32 cases); auricular Shenmen (TF4) and sensitive spot at the distribution area of auricular vagus nervus were chosen in the ear acupuncture group (group C, 32 cases). Six days made one session and the treatments were finished after 4 courses. The polysomnography (PSG) and Pittsburgh sleep quality index (PSQI) were employed before and after treatment to evaluate the alleviation of insomnia.

RESULTSThe parameters of the sleep latency (SL), rapid wave sleep latency (RL) and sleep efficiency (SE) were significantly improved in the three groups, and the differences were statistically significant (P < 0.05, P < 0.01). The SL and awaking time (AT) in group C [SL (401.08 +/- 16.54) min and AT (4.87 +/- 2.64) times] were significantly superior to those in the other two groups [SL (50.36 +/- 18.47) min, (54.87 +/- 20.92) min, AT (5.98 +/- 2.11) times, (6.13 +/- 3.04) times, all P < 0.05]. The S(3+4) (%) in group C was also significantly higher than those in the other two groups (both P < 0.05). It was indicated by PSQI that the sleep quality of group C (0.78 +/- 0.12) was significantly superior to that in group B (1.32 +/- 0.29), the total score and cured and markedly effective rate in group C [(4.34 +/- 1.43), 68.8% (22/32)] were superior to those in group A [(7.48 +/- 3.09), 53.1% (17/32), both P < 0.05].

CONCLUSIONEar acupuncture has a better curative effect than the restore interaction between the heart and the kidney group and acupuncturing qiao mai group, it is worth of being promoted.
