Objective:To explore the safety and efficacy of ultrasound-assisted facial filler injection, based on the anatomy of facial vessels to prevent intravascular embolization.Methods:From Jan. 2019 to Sep. 2020, 142 patients were treated with facial soft-tissue filler injection (mean age, 39.7 years; 131 female and 11 male). According to the patients＇ own will, autologous fat or hyaluronic acid was applied respectively. When injecting, the assistant could press over the periorbital artery to temporarily occlude the artery, confirmed with Doppler ultrasound, thus reduced the risk of intravascular embolization, and carefully injected with minimal pressure and tiny amount.Results:A total of 142 patients were enrolled in the study, and 54 patients were treated with autologous fat grafting, while 88 patients were injected with hyaluronic acid. The injection sites included forehead, temple, glabella, nasal root, tear trough, nasolabial fold, cheek, chin, and lips. Facial rejuvenation improvement was satisfied with a smooth contour and proper augmentation. No vascular embolization occurred. 9 patients received a second or third round fat grafting to achieve better outcome. Follow-up duration ranged from 1 month to 6 months.Conclusions:With ultrasound assistant, digital pressure over the orbital artery could temporarily occlude the artery and may reduce the risk of intravascular embolization. The simple technique may add a significant benefit with no additional cost or risk to the patients.

Objective:To evaluate the clinical efficacy of Sini-Jia-Huanglian Decoction on chronic heart failure (CHF) with qi deficiency and blood stasis syndrome. Methods:A total of 100 patients with CHF and qi deficiency and blood stasis syndrome in Handan Mingren hospital from January 2018 to June 2019 who met the inclusion criteria were divided into two groups according to the random number table method, 50 cases in each group. The control group was treated with conventional western medicine therapy, and the treatment group was treated with Sini-Jia-Huanglian Decoction on the basis of the control group. Both groups were treated for 30 days. TCM syndrome score was performed before and after treatment. The level of N-terminal-pro-B-type natriuretic peptide (NT-proBNP) was detected by radioimmunoassay. The levels of peptide and galectin 3 (Gal-3) were detected by ELISA. The exercise tolerance was measured by 6-minute walking test, the clinical efficacy was tevaluated. Results:The total effective rate of the treatment group was 92.0% (46/50), and the control group was 76.0% (38/50), there was significant difference between the two groups ( χ2=4.762, P=0.029). After treatment, the scores of shortness of breath, palpitation, dyspnea, dizziness, chest pain and total scores in the treatment group were significantly lower than those in the control group ( t values were 4.257, 8.493, 8.211, 4.481, 5.500, 6.977, respectively, all Ps<0.01). After treatment, the levels of NT-proBNP (2 349.61 ± 683.50 ng/L vs. 3 026.27 ± 714.35 ng/L, t=4.840), and peptide (12.16 ± 3.43 ng/L vs. 17.52 ± 3.98 ng/L, t=7.214) and Gal-3 (3.01 ± 0.82 μg/L vs. 3.94 ± 0.93 μg/L, t=5.304) in the treatment group were significantly lower than those in the control group ( P<0.01), and the walking distance of 6 minutes (450.66 ± 79.25 m vs. 384.49 ± 70.16 m, t=4.421) was significantly longer than that of the control group ( P<0.01). Conclusions:The Sini-Jia-Huanglian Decoction can improve the heart function and clinical symptoms of CHF patients with qi deficiency and blood stasis syndrome, and improve the clinical efficacy.

Objective: To investigate the clinical efficacy and safety profile of hyaluronic acid dermal filler(Restylane®) in treating nasolabial folds in Chinese population. Methods: 103 subjects in this study were recruited from five Chinese clinical trial centers between July 2014 and December 2015. Subjects were treated with hyaluronic acid dermal filler in correcting nasolabial folds and an optional re-treatment was performed after 12 months according to the subjects′wishes. The improved of nasolabial folds was evaluated by the change of severity (wrinkle severity rating scale, WSRS) and aesthetic improvement (global aesthetic improvement scale, GAIS). Satisfaction of subjects on treatment was evaluated using subject satisfaction questionnaires (SSQ). Safety indicators such as pain, skin and soft tissue presentation at the injection site were continuously evaluated throughout the whole treatment process. Results: Significant improvement in scores of WSRS and GAIS of all subjects was observed after treatment. Nine months after treatment, the scores of WSRS in 80 subjects (77.7%) and GAIS in 96 subjects (93.2%) were still improved. The 68 subjects (95.8%) received re-treatment after 12 months gained further improvement in nasolabial folds. Most adverse events were mild or moderate (transient/reversible local manifestations) and all resolved before study end, no severe adverse event related to products observed. Conclusions Hyaluronic acid dermal filler is effective and safe in treatment of nasolabial folds in Chinese population and the effect can last up to 12 months.

Objective To explore the clinicopathologic characteristics of polyomavirus nephropathy (PyVN) in renal transplantation.Methods Clinicopathological data from 101 cases of PyVN from January 2006 to October 2016 in our hospital were collected and analyzed retrospectively.There were 72 males and 29 females.The mean time from operation to the diagnosis of PyVN was 16.5 months (2.2-63.9 months),with 86 cases (85.1％) occurring within 2 years.The indications for biopsy included elevated serum creatinine in 81 cases (80.2％),elevated serum creatinine with proteinuria in 13 (12.9％) cases,active BK virus(BKV) infection in 5 cases (5.0％) and proteinuria in 2 cases (2.0％).Results BK viruia was detected in 98 (97.0％) recipients with viral loads of 1.5 × 109 (0-9.0 × 1011) copies/ml,and BK viremia in 80 (79.2％) recipients with viral loads of 1.8 × 104 (0-2.1 × 107) copies/ml.5 patients lost their graft function at biopsy and the other 96 patients reserved graft function with serum creatinine of 187.0 μmol/L.After 20.1 (3.7-109.6) months of follow-up,19 (18.8％) patients lost their graft function.The average serum creatinine of the 77 patients with graft function was 165.0 μmol/L,with no statistical difference (P ＞ 0.05) compared with that of patients at diagnosis.There were 18 cases of stage A,72 cases of stage B and 11 cases of stage C with 5-year allograft cumulative survival of 92.9％,82.8％ and 55.6％,respectively.Conclusions PyVN can occur within 5 years after renal transplantation,mostly within 2 years.The typical clinical manifestations include elevated serum creatinine,BK viruia and BK viremia.The severe the histopathological lesions were correlated the worse the clinical prognosis.

Objective: To observe the safety and efficiency of face-lift combined with fat grafting in facial rejuvenation. Methods: We performed a retrospective study, which included 23 patients. SMAS suspension and multi-site suspension were combined to correct the nasolabial fold, mid-cheek aging and malar mounds. Structural fat grafting was performed to treat the volume loss in mid-face. Results: All patients demonstrated a significant improvement in midfacial appearance. No infection or nerve injury were found in this study. Only three patients did not get primary healing in temple region, which led to temporal hair loss from secondary healing. Conclusions This study demonstrates that fat grafting and multiple layers face-lift are efficient method for facial rejuvenation. These approaches appear to be very promising for facial anti-aging techniques.

Objective: This paper discusses a surgical method to improve the middle part of face and the temporal surface by using the patented technology of embedding guidance technology. Methods: On the basis of not removing the skin, the application of embedding guidance technology was applied to achieve the effect of facial lifting by placing a 2-0 polyester knitting line under the scalp with a minimally invasive incision(3-5 mm) , paving up to the skull periosteum and down to the hairline edge for compound fixation. Results: Among the 200 patients, 197 were female and 3 were male. Aging from 23-62 years old, all of the patients suffered from mild to moderate problem of saggy skin.Post-operation follow-up was kept from 3 months to 5 years after the treatment, which demonstrated that all of the patients showed different degrees of facial lifting after edema subsided at 3 months, including improvedfacial skin condition, shallower nasolabial groove, lifting of the lateral canthus and tightening of facial skin. The patients were satisfied with the effect. Conclusions The surgical method is an effective method to solve the problem of facial aging with advantages, such as simple execution, minimized wound, fast recovery, no post-operation bandage requirement and showing great result towards patients suffering from mild and moderate saggy facial skin problem.

Objective: To explore the clinical effect of cervico-acromial fasciocutaneous flap based on the supraclavicular artery as a method for face and neck reconstruction. Methods: From Oct 1990 to June 2014, 17 patients, with the age range of 7 to 51 years, suffering from cicatricle contractures of neck or facial defect, were treated with cervico-acromial fascicutaneous flaps. 29 flaps were used in 12 patients bilaterally or multiply. The donor sites of 2 patients were closed by skin graft; while in the rest 15 patients, the donor sites were closed by expanded flaps. Results: All the 29 flaps were survived, with satisfactory color and texture. Hematoma occurred in 1 case after tissue expander implantation, but the flap was successfully expanded after evacuation of hematoma. The size of flaps ranged from 15 cm×7 cm to 35 cm×15 cm. 10 patients completed 6 months follow-up, and presented with satisfactory appearance and better functional results. Conclusions Cervico-acromial fascicutaneous flap based on the supraclavicular artery is an good choice for reconstruction of neck and facial defects.

Objective: To explore the effects of cigarette smoke exposure during pregnancy on the quality of oocytes and the whole genome DNA methylation in the offspring of female mice during the period of germinal vesicle (GV) . Methods: The pregnant 7 d mice were divided into 3 groups, exposure on the 0, 0.5, 1 lit cigarettes cabinet (volume 18 L) , at 9 am and 3 pm for 1 h twice daily, until delivery. When the mice were 6 weeks old, the organ index and the number of follicles in the ovary were detected by weighing and making HE stained sections. GV stage oocytes were obtained by Hoechst 33342 staining and indirect immunofluorescence to detect the quality of oocytes, chromatin configuration and whole genome DNA methylation level. Results: Compared with the control group and low dose group, the offspring ovarian organ index of female mice in the high dose group decreased, the difference was statistically significant (P<0.05) . Compared with the control group, the number of follicular oocytes in low dose group and high dose group female mice offspring decreased, the zona pellucida oocytes diameter decreased, and the zona pellucida thickness increased, the differences were statistical significance (P<0.05) . Compared with control group and low dose group, in the high dose group, the oocytes nucleus diameter of the female mice offspring decreased, the proportion of nucleolus surrounded type chromatin configuration (SN) decreased, and the proportion of nucleoil not surrounded type (NSN) increased, the relative fluorescence intensity of 5MeC decreased, the differences were statistically significant (P<0.05) . Conclusion Exposure to cigarette smoke during pregnancy may reduce indicators of offspring ovarian organ index, female rat follicle number and oocyte quality change, the high dose group can lead to oocyte chromatin structure and DNA methylation level anomaly.
