ABSTRACT

Objective:To use three-dimensional (3D) scanning to measure the preoperative and postoperative nasal parameters of the patients received rhinoplasty with ear cartilage and silicone prosthesis, and to evaluate the clinical effect of the surgery.Methods:Sixteen female patients with an average age of 28.3 years, ranged from 21 to 35 years, received rhinoplasty with ear cartilage and silicone prosthesis in Wuhan Tongji Hospital from June 2018 to February 2019. Preoperative and postoperative 3D scanning was performed to measure nasal parameters, including linear length, angle, and proportional index.Results:All patients were satisfied with the postoperative outcomes. The postoperative nasal length, nasal height, and nasal depth increased significantly, and the postoperative nasal width and nasal tip width decreased. The postoperative nasolabial angle and nasofrontal angle were statistically improved, while the preoperative and postoperative data of columellar facial angle, nasal tip angle, and nasal column-lobular angle were not significantly different. The ratios of nasal depth and nasal width, nasal index and nasal tip protrusion were improved after surgery, while the postoperative ratios of nasal columella and nasal lobules length were not statistically improved.Conclusions:The 3D scanning allows for comprehensive and accurate measurement of the nasal parameters. The rhinoplasty with ear cartilage and silicone prosthesis is more effective in improving the overall contour of the nose, but less effective in improving the aesthetics of the nasal tip.

ABSTRACT

【Objective】 To investigate and analyze the current situation of the human resources as well as blood collection and supply of blood banks of Zhejiang Province, so as to understand the problems existing in the development of human resources and put forward suggestions. 【Methods】 Questionnaires were issued to Blood Center of Zhejiang Province, municipal central blood stations, and county-level central blood banks to investigate the relevant data in 2015 and 2019. Meanwhile, some data were obtained through the Zhejiang Blood Management Information System (BIS3.0), symposiums, and querying medical service data. Statistical analysis was carried out. 【Results】 Among the 28 blood banks, filled the questionnaires, 927 personnel were in accordance with the authorized strength, accounting for 62.26% (927/1 489), and 1069 health technicians, accounting for 71.519% (1 060/1 489). From 2015 to 2019, the annual growth rate of human resources in blood banks was 2.02%, lower than the annual growth rate of whole blood collection volume 4.83% and the annual growth rate of clinical blood supply (red blood cell) 4.82%, lagging behind the annual growth rate of 6.55%, 8.71% and 12.36% in the number of diagnoses, inpatients and surgeries in the hospitals across the province. The average annual growth rate of doctors and nurses in blood banks was 0.17% and 1.67%, lower than that of licebsed doctors and registered nurses of the province, which was 6.78% and 8.27%, respectively. 【Conclusion】 With the development trend of blood collection and supply, the personnel allocation and the proportion of health technicians of blood banks across Zhejiang Province is insufficient. It is suggested to establish a manpower allocation standard suitable to the business volume, give priority to properly solvement of the current employment, strengthen training, and improve the efficiency of physical examination consultation, testing and phlebotomy positions.

ABSTRACT

Objective@#To explore the regulatory mechanism of E2F1 transcription factor on M2 macrophages in full-thickness skin defect wounds of mice.@*Methods@#E2F1 gene knockout heterozygotes C57BL/6 mice and wild-type C57BL/6 mice were introduced and self-reproduced. Two weeks after birth, E2F1 gene knockout homozygotes mice and wild-type mice were identified by polymerase chain reaction (PCR). Twelve identified 6-8 weeks old male E2F1 gene knockout homozygotes C57BL/6 mice and wild-type C57BL/6 mice were selected respectively according to the random number table and set as E2F1 gene knockout group and wild-type group. A full-thickness skin defect wound was made on the back of each mouse. On post injury day (PID) 2 and 7, 6 mice in each group were selected according to the random number table and sacrificed, and the wound tissue was excised. The expression of CD68 and CD206 double positive M2 macrophages was observed by immunofluorescence method, and the percentage of CD206 positive cells was calculated. The protein expression of CD206 was detected by Western blotting. The mRNA expression of arginase 1 was detected by real-time fluorescent quantitative reverse transcription PCR (RT-PCR). Wound tissue specimens of the two groups on PID 7 were obtained, and the protein and mRNA expressions of peroxisome proliferator-activated receptor gamma (PPAR-γ) were detected by Western blotting and real-time fluorescent quantitative RT-PCR respectively. The above-mentioned experiments were repeated four times. Three specimens of wound tissue of mice in wild-type group on PID 7 were obtained to detect the relationship between E2F1 and PPAR-γ by co-immunoprecipitation and Western blotting, and this experiment was repeated two times. Data were processed with unpaired t test.@*Results@#The size of PCR products of E2F1 gene knockout homozygotes C57BL/6 mice and wild-type C57BL/6 mice were 227 and 172 bp respectively, which were the same as those of the designed DNA fragments. On PID 2 and 7, the number of CD68 and CD206 double positive M2 macrophages in the wound tissue of mice in E2F1 gene knockout group was more than that of wild-type group, and the percentages of CD206 positive cells in the wound tissue of mice in E2F1 gene knockout group were (0.234±0.032)% and (0.584±0.023)% respectively, which were significantly higher than (0.129±0.017)% and (0.282±0.071)% of wild-type group (t=3.29, 3.54, P<0.05). On PID 2 and 7, the protein expression of CD206 in the wound tissue of mice in E2F1 gene knockout group were 1.00±0.23 and 1.63±0.26 respectively, which were significantly higher than 0.43±0.06 and 0.97±0.08 of wild-type group (t=2.41, 2.45, P<0.05). On PID 2 and 7, the mRNA expressions of arginase 1 in the wound tissue of mice in E2F1 gene knockout group were 0.482±0.105 and 0.195±0.031 respectively, which were significantly higher than 0.163±0.026 and 0.108±0.017 of wild-type group (t=3.04, 2.86, P<0.05). On PID 7, the protein and mRNA expressions of PPAR-γ in the wound tissue of mice in E2F1 gene knockout group were 0.61±0.12 and 0.51±0.13 respectively, which were significantly higher than 0.20±0.04 and 0.20±0.04 of wild-type group (t=3.36, 2.86, P<0.05). On PID 7, detection of the wound tissue of mice in wild-type group showed that PPAR-γ had unidirectional effect on E2F1.@*Conclusions@#E2F1 transcription factor affects the polarization of M2 macrophages by inhibiting the expression of PPAR-γ, thereby inhibiting the healing process of full-thickness skin defect wounds in mice.

ABSTRACT

Objective@#To compare the clinical efficacy and patient satisfaction of 755 nm semiconductor laser for hair removal during different stages of auricular reconstruction.@*Methods@#From July 2016 to September 2018, 86 patients who had ear reconstruction underwent 755 nm semiconductor laser for auricle hair removal in plastic surgery department of Tongji hospital affiliated to Tongji medical college of Huazhong university of science and technology. There were 39 males and 47 females with an average age 12 years old(from 6 to 28 years old). 28 cases were left ear, 58 cases were right ear. With random grouping, 40 patients underwent auricle hair removal treatment after posterior ear tissue expander implantation (post-operation of stage Ⅰ depilation group) and 46 patients underwent treatment after auricular reconstruction (post-operation of stage Ⅱ depilation group). Auricle hair removal treatments(pulse width 10-20 ms, wave length 755 nm, spot size 10 mm×15 mm, energy density 4-8 J/cm2) were respectively started at different intervention time. Each treatment time were 5-10 minutes. The end of the treatment was slight redness or edema of the local hairy follicle. The treatment was repeated every 4 weeks with a total of 5 times. The number of adverse reactions was recorded as while as the hair density, hair clearance rate and patient satisfaction before treatment and 6 months after the 5th depilation.@*Results@#Patients in both groups successfully were completed the treatment and were followed up to about 6 months (23 to 25 weeks) after the last depilation treatment. There were only 2 cases with scratch in skin preparation and 2 cases with blisters in the postoperative of stage Ⅱ group. None of the other patients had adverse reactions. Hair density after treatment (27.63±7.75 bar/cm2) was less than before treatment (84.55±13.68 bar/cm2) in post-operation of stage Ⅰ depilation group. Hair density after treatment was 40.52±5.92 bar/cm2 in post-operation of stage Ⅱ depilation group, less than before treatment (74.78±11.19 bar/cm2). The differences were statistically significant (both P<0.001). After hair removal, the hair density of post-treatment in the post-operation of stage Ⅰ depilation group was less than the post-operation of stage Ⅱ depilation group. The difference was statistically significant (P=0.000). The hair clearance rate of the post-operation of stage Ⅰ (67.32%) was higher than the post-operation of stage Ⅱ(45.81%). The difference was statistically significant (P<0.001). Patients’ satisfaction was 87.5% in the post-operation of stage Ⅰ and 69.5% in the post-operation of stage Ⅱ. The former was superior to the latter.@*Conclusions@#Auricle hair removal with semiconductor 755 nm laserstarted at stage Ⅰ that posterior ear tissue expander was implanted has more favorable clinical efficacy, and higher patient’s satisfaction rate.

ABSTRACT

Objective@#The study is to assess the accuracy and reliability of three-dimensional simulated magnetic resonance imaging with silicone-excitation SPACE (sampling perfection with application optimized contrast using different flip angle evolutions) sequence for estimating implant volume.@*Methods@#(1) MRI examinations of 10 silicone implants (Wuhan Tongji Hospital from October 2018 to December 2018) were performed with T2, H2O-excitation SPACE sequence (T2-spc-H2O) and silicone-excitation SPACE sequence (T2-spc-Silicone) to find the most accurate method to estimate implant volume by ITK-SNAP. The effect of implant deformation and slice thickness of T2-spc-Silicone on volume measurement were investigated. (2) 13 normal patients and 6 patients with implant complications (Wuhan Tongji Hospital from March 2017 to May 2019) were enrolled for testing the accuracy and reliability of T2-spc-Silicone for volume measurement in vivo. The data were analyzed using Prism 8.0 software. The paired student t-test was used to compare the difference of two groups. One-way ANOVA was used to compare the difference of multiple groups. P<0.05 was considered statistically significant.@*Results@#The absolute volume differences of T2, T2-spc-H2O, T2-spc-Silicone were (42.19±2.31) ml, (23.27±1.55) ml and (6.28±1.22) ml. The absolute volume differences of T2-spc-Silicone group was significantly less than T2-spc-H2O and T2 group in vitro(F=195.3, P<0.001). No significant difference(F=1.36, P=0.22)was shown between the normality group and the deformation group for estimating the volume of implants with the slice thickness of SPACE increased from 0.5 mm×0.5 mm×0.5 mm to 5.0 mm×5.0 mm×5.0 mm. Besides, the slices thickness of SPACE from 0.5 mm×0.5 mm×0.5 mm to 5.0 mm×5.0 mm×5.0 mm did not significantly affect the accuracy of volume measurement of the implants in deformation state(F=1.22, P=0.29). The measurement error of SPACE was (8.82±0.99) ml in normal patients. Moreover, there was no significant difference between measured volume[(226.4±12.76)ml] and actual volume of implants[(225.9±11.94) ml](t=0.31, P=0.76)in patients with implant complications. The result showed excellent intraobserver reliability (ICC=0.997) and internal consistency ranged from 0.986 to 0.997 (P<0.001).@*Conclusions@#The method to measure implant volume by silicone-excitation SPACE sequence had desirable accuracy and reliability. The deformation of the implant and the slice thickness of the SPACE sequence did not exhibit a significant effect on the accuracy of volume measurement.

ABSTRACT

Objective To detect and analyze the levels of preoperative serum carcino-embryonic antigen (CEA) and CA15-3 in early invasive breast cancer patients and their correlation with pathological parameters. Methods Electrochemical luminescence immunoassay (ECLI) technology was used to detect serum levels of CEA and CA15-3 in 223 cases of early invasive breast cancer patients, 109 patients with benign lesions, and 30 cases of heath control. Immunohistochemical (IHC) and fluorescence in situ hybridization (FISH) were used to detect the estrogen receptors (ER), progesterone recepter (PR), and its HER-2 pathological indicators.Besides, the correlation of serum CA15-3, CEA levels and pathological parameters was analyzed. Results The serum CA15-3 and CEA levels of Breast cancer patients [(22.27±15.11) U/ml, (5.03± 0.49) μg/L] were significantly higher than that of patients in benign lesion group [(14.13±3.04) U/ml, (2.72± 0.11) μg/L] (P0.05). CEA positive rate of breast cancer group was significantly higher than that of benign lesions(13.5%vs. 3.7%, 26.5%vs. 1.8%, P<0.05). 30 cases of normal control group had no positive one. The joint monitoring sensitivity of CEA and CA15-3 breast cancer group was 9.4 %, the sensitivity was 0 in benign lesion group. There was significant difference (P < 0.05). Conclusion The changes of Serum CA15-3 and CEA levels in breast cancer patients can be considered as the judgment standard for early diagnosis, pathological staging, prognosis and clinical effect monitoring.

ABSTRACT

Objective To evaluate the effects of long-term high-fat diet on skin wound repair in mice, and to explore its related mechanism. Methods A total of 16 ten-week-old C57BL/6J wild-type mice were randomly and equally divided into two groups to be fed a high-fat diet(HFD group)and a standard diet(SD group)respectively for 8 weeks. Then, an 8-mm full-thickness skin wound was created on the back of each mouse by using a biopsy punch. The degree of wound healing was observed, wound healing rate and epithelialization level were evaluated every day. The weight of mice was measured before feeding, after 8-week feeding and on day 14 after the operation. Peripheral blood samples were obtained from these mice for the determination of total cholesterol(TC)and triglyceride(TG)levels after a 12-hour fast on day 14 after the operation. Then, all the mice were sacrificed, and wound tissues were resected from the dorsal skin of mice for a histological study. The two-sample t test was used to compare the thickness of new epidermis in the wound surface, collagen deposition rate in the wound bed, count of new vessels, levels of cell proliferation and degree of inflammatory cell infiltration between the two groups. Results The average weight of mice was significantly higher in the HFD group than in the SD group after 8-week feeding(27.3 ± 0.7 g vs. 21.2 ± 0.6 g, t = 21.98, P 0.05). Conclusion Long-term high-fat diet can affect wound healing and delay skin wound repair in mice.

ABSTRACT

This study examined the effects of a combined surgery of sleeve gastrectomy (SG) and modified jejunoileal bypass (JIB) on the body weight, food intake, and the plasma levels of active glucagon-like peptide-1 (GLP-1) and total ghrelin of rats. Rats were divided into 3 groups in terms of different surgical protocol: SG-JIB (n=12), SG (n=12), JIB (n=12) and sham surgery groups (n=10). In SG-JIB group, rats was subjected to sleeve gastrectomy and end to side anastomosis of part of the jejunum (25 cm from the ligament of Treitz) to the ileum 25 cm proximal to the cecum. The body weight and food intake were evaluated during 10 consecutive weeks postoperatively. The levels of active GLP-1 and total ghrelin in the plasma of the rats were measured by ELISA assay. The results showed that the SG-JIB treated rats relative to SG- or JIB-treated ones produced a sustained reduction in food intake and weight gain. The level of active GLP-1 was elevated and total ghrelin level decreased in SG-JIB-treated rats as compared with SG- or JIB-treated ones. It was concluded that SG-JIB could efficiently reduce the body weight and food intake, alter obesity-related hormone levels of the rats, indicating that SG-JIB may be potentially used for the treatment of obesity.

ABSTRACT

Objective To construct and analyze the model of the sleeve gastrectomy with modified jejunoileal bypass (SG/MJIB) on non-obese Goto - kakizaki (GK) rats. Methods GK rats were randomly divided into SG/MJIB, sham-SG/MJIB, pair-fed (PF) and controls group. Before and after surgery, the changes of weight, food intake, fasting glucose, oral glucose tolerance test (OGTT), insulin tolerance test (ITT), fasting plasma Insulin and the histological changes in islet were dynamically observed for 16 weeks. Results From the 4th week postoperative, the weight changes of SG/MJIB significantly decreased compared with sham-SG/MJIB and PF group (P<0.01). Fasting glucose concentration of SG/MJIB animals was lower than sham-SG/MJIB, PF and controls group (P<0.05). The OGTT of SG/MJIB rats was obviously improved compared with the sham-SG/MJIB, PF and controls group (P<0.01). Two weeks after operation, glucose tolerance was better improved in SG/MJIB than preoperative, the area under the curve (AUC) of blood glucose concentration decreased by about 38.9% (P<0.01). Postoperative insulin levels in SG/MJIB group were obviously lower than sham-SG/MJIB group throughout the experiment(P<0.05). In the 16th week, the morph of pancreatic islet of SG/MJIB was obviously improved. In the SG/MJIB group, the number of positive β-cell and mature acinus was significantly increased, while sham surgery groups had no obvious changes as mentioned above. Conclusions SG/MJIB was directly linked to the reduction in glucose levels in GK rats, independently weight loss and caloric intake, and it can be served asa stable long-lasting hypoglycemic surgery model to research the mechanism for the treatment of type 2 diabetes.

ABSTRACT

Objective To evaluate the clinical efficacy of 5-aminolevulinic acid-induced photodynamic therapy (ALA-PDT) in the treatment of condyloma acuminatum. Methods Thirty-six cases of condyloma acuminatum were treated with ALA-PDT. Results After the treatment, 33 (91.67%) patients were cured, 35 (97.22%) improved. Relapse occurred in 3 (8.33%) patients. Side effects were noted in 2 (5.56%) patients. Conclusions ALA-PDT is a relatively simple, effective and safe treatment with a lower recurrence rate for condyloma acuminatum, especially for small skin lesions or lesions at specific area. However, the high expense required for multiple treatments with ALA-PDT may restrict its application.

ABSTRACT

Objective To determine the effect of different serum insulin-like growth factor-Ⅰ(IGF-1)levels on mouse cancer.Methods A total of 120 male mice at 6 weeks of age(60 control mice and 60 LID mice)were subcutaneously injected colon tumor CT26 cell line.Each group was random divided into two subgroups respectively,every 10 mice of one subgroup were injected subcutaneously with growth hormone(GH)(1ms/kg)daily from the 10th,14th and18th days respectively until the 22nd days,and the other subgroup received saline injection.Results All mice treated with GH have higher level of IGF-1,compared with those treated with saline.High level of IGF-1 promoted the development of cachexia in these mice treated with GH from the 10th days.However,the level of IGF-1 has negative correlation with the cancer cachexia state for mice treated with GH from the 14th days.Conclusion Circulating IGF-1 and GH play an important role in tumor growth 4nd cachexia development in the early stage of cancer and can ameliorate the state of cachexia in the advanced stage.

ABSTRACT

In order to investigate the effects of rhGM-CSF on apoptosis of HL-60 cells induced with VP-16 treatment, HL-60 cells were first incubated with rhGM-CSF before they were treated with VP-16. The apoptosis processes and the changes in apoptosis related gene bcl-2 and fas expression were observed. The morphological and ultrastructural changes were observed under optics microscope and electromicroscope. DNA fragmentation were detected by agarose gel electrophoresis, the apoptotic rate, bcl-2 and fas expression with flow cytometry. Our results showed that rhGM-CSF inhibited the apoptosis of HL-60 cells induced with VP-16 treatment, which enhanced the down-regulation of bcl-2 expression, but inhibited the up-regulation of fas expression. So it suggested that rhGM-CSF can decrease the sensitivity of HL-60 cells to VP-16, probably by down-regulation of fas expression.
