Objective To observe the clinical characteristics of gestational diabetic retinopathy (DR)of 13 pregnants with vitreous hemorrhage.Methods The clinical data of 26 eyes retinopathy with 13 cases of gestational diabetes were retrospectively analyzed.After bilateral eyes were mydriatic by Pyrazole MAO amine compound,ophthal-mologist used fundus camera to check bilateral fundus.B ultrasonic was used to examine vitreous hemorrhage and the surfaces of vitreous and retinal.Results In 13 cases,26 eyes vision were between hand motion-0.6.Sudden vitre-ous hemorrhage in 13 eyes,accounted for 50.0%(13/26).Among them,the classⅠvitreous hemorrhage in 10 eyes, 76.9%(10/13).Ⅱ,Ⅲ grade vitreous hemorrhage in 2 eyes,15.4%(2/13).LevelⅣvitreous hemorrhage in 1 eye, accounted for 7.7%(1/13).26 eyes were diagnosed with stage IV(early or fiber hyperplasia period)DR.The fundus photography:the size,number of retinal neovascularization were found in 13 eyes without vitreous hemorrhage.Ultra-sound confirmed that the 13 eyes vitreous hemorrhage were fresh bleeding,and found 4 eyes with fiber membrane, accounted for 30.8%(4/13).The eyes without vitreous hemorrhage were timely treated by laser,and the eyes with vitreous hemorrhage were treated by stage laser treatment according to the condition of vitreous hemorrhage absorp-tion.Followed up for 4 to 6 months,in a stable condition.Conclusion Obstetrics and gynecology doctors and oph-thalmologists should pay attention to pregnancy DR with vitreous hemorrhage.Because they are all early or fiber hyper-plasia period.Timely and reasonable laser treatment can prevent permanent damage of visual function.

OBJECTIVETo investigate the application of medpor and split-thickness skin graft in formation of cranioauricular sulcus during auricular reconstruction with Nagata method.

METHODSThe first stage operation was fulfilled according to the Nagata two-stage method which involves fabrication and grafting of the costal cartilage framework. The second-stage ear elevation operation was undertaken 6 months later to form the cranioauricular sulcus. Split-thickness skin was taken from temporal and accipital area. After releasing the auricular framework and transplanting C shaped medpor at the rear side of framework, the temporaparietal fascia flap was transferred to cover postauricular medpor and framework. Then the split-thickness skin graft was implant on the fascia surface.

RESULTSFrom July 2010 to August 2012, 20 cases (22 ears) were treated. Partial necrosis of temporaparietal fascia flap and framework exposure happened in 1 case. Successful ear reconstruction was achieved in other cases with satisfactory cranioauricular sulcus during the follow-up period of 6-18 months (average, 13 months).

CONCLUSIONSThe application of medpor and split-thickness skin graft in the ear elevation of Nagata method for auricular reconstruction for microtia can achieve satisfactory results. It not only avoids the obvious scar in the donor site due to harvesting full-thickness and intermediate-thickness skin, but also reduces chest trauma due to harvesting costal cartilage.

Methods Pediatric patients who were checked by long-range V-EEG from April 2014 to March 2015 were chronologically divided into experimental group ( n=169 ) and control group ( n =142 ) . The patients of experimental group were cared by unified nursing intervention while the patients of control group were implemented traditional nursing. Contrast was implemented between two groups according to leads and electrode off, sleep deprivation situation, completion of provocation test, rash and trauma. Results After the implementation of V-EEG monitoring nursing regulations, the incidences of leads off, artifact, failure of sleep deprivation, and trauma were lower than those of the control group (P<0. 05); the cooperation of children having hyperventilation increased in the experimental group with low failure rate of opening and closing eyes stimulation and flush stimulation (P<0. 05). The parent′s satisfaction increased from 78.87% to 94.08% (P <0. 01). Conclusions Standardized nursing can effectively improve the quality of V-EEG monitoring, decline the incidence of artifact, make the V-EEG report more accurate and completed, and promote parent′s satisfaction.

Objective To explore the trend of preductal pulse oxygen saturation (SpO2) during 10 min after birth in newborns born at different gestational age and through different delivery mode.Methods From May 2014 to August 2014,319 neonates,born in Tianjin Central Hospital of Obstetrics and Gynecology and whose Apgar score at 1 min after birth ≥ 8,were included into the study.Term infants were grouped into vaginal delivery group (n=102) and caesarean group (n=117) according to the delivery mode.Infants born through caesarean section were divided into three groups,including 30-33+6 weeks (n=50),34-36+6 weeks (n=50) and 37-41+6 weeks (n=117) group according to the gestational age at birth.Immediately after the umbilical cord clamped,preductal SpO2 was recorded at each minute from one to ten minutes using the pulse oximetry.Oneway analysis of variance and two independent sample t test were applied for statistical analysis.Results At each time point within ten minutes after birth,the preductal SpO2 for preterm infants of 30-33+6 weeks gestation in the caesarean group were (54± 3)％,(59± 3)％,(65 ±4)％,(70±4)％,(75 ±4)％,(80±4)％,(84± 3)％,(89± 3)％,(91 ± 3)％ and (93 ± 2)％,respectively,which were significant lower than those of the 34-36+6 weeks group [(57 ± 5)％,(66 ± 4)％,(72 ± 6)％,(78 ± 6)％,(83 ± 6)％,(87 ± 6)％,(90± 5)％,(92 ± 4)％,(94± 4)％ and (95 ± 4)％,respectively] and of the term infants [(58 ± 3)％,(67 ± 4)％,(73 ± 5)％,(78 ± 6)％,(83 ± 6)％,(87 ± 6)％,(90± 5)％,(92± 5)％,(94± 3)％ and (95± 3)％,respectively] (all P ≤ 0.05).While the corresponding preductal SpO2 for term infants in the vaginal delivery group were (61 ± 6)％,(69± 7)％,(75 ± 6)％,(81 ± 7)％,(86± 6)％,(90 ± 6)％,(93 ± 5)％,(94± 4)％,(95 ± 4)％ and (96 ± 3)％,respectively,which were all higher than those of term infants in the caesarean group (all P ≤ 0.05).Conclusions The preductal SpO2 for preterm infants of 30-33+6 weeks of gestation is lower than that of preterm and term infants of ≥ 34 weeks of gestation at all time points within ten minutes after birth.The preductal SpO2 for term infants born through vaginal delivery is higher and rising faster than that of term infants born through caesarean section at all times.

Objective To study the relationship between polymorphism of NAT2 gene and the susceptibility of osteosarcoma. Methods Using serum samples of patients with osteosarcoma , NAT2 gene polymorphism was determined by PCR-RFLP to observe M1, M2 and M3 mutant genes, NAT2 genotype and allele distribution. Slow acetylation and rapid acetylation genotype between groups in the distribution were also detected. Moreover , the relationship between the clinical characteristics of osteosarcoma and NAT2 genetic polymorphism were analyzed. Results From January 2010 to September 2015, 126 patients with osteosarcoma were enrolled as a case group, and 119 healthy persons in the same period were as the control group. In the control group, the frequency of NAT2 genotype (homozygous wild type (wt/wt and miscellaneous synthetic mutant WT/ MX, homozygous mutant MX/MX) were 30.95%, 50.79% and 18.25% respectively; In the experimental group were 47.06%, 46.22% and 6.72% respectively. The frequency of the two groups was statistically significant (P <0.05). Rapid NAT2 acetylator genotype of suffering from the risk of osteosarcoma 1.782 times slow acetylation genotype (P < 0.05). Compared to rapid acetylation genotype patients with osteosarcoma, slow acetylation genotype patients has smaller tumor volume (P = 0.008),lower differentiation degree of tumor (P = 0.011) and less occurrence of distant metastasis (P = 0.001). Conclusion The rapid acetylation genotype of NAT2 gene may be a risk factor for osteosarcoma.

Objective: To explore the clinical effect of the multi-point, multi-level suspension as well as fixation using midfacial soft-tissue spaces for midface lifting. Methods: A total of 65 patients with aging midface were admitted at the First Affiliated Hospital of Fujian Medical University from October 2017 to February 2019. Among them, 47 patients underwent primary blepharoplasty and midface lifting. Eighteen patients, including 5 patients with lower eyelid retraction or ectropion after blepharoplasty, underwent secondary midface lifting after blepharoplasty. The preseptal space was separated under orbicularis oculi muscle by palpebral margin incision. The orbicularis retaining ligament and the tear trough ligament were severed through preperiosteal plane. The preseptal space was connected with premaxillary space and prezygomatic space. The malar fat pad and superficial fascia were vertically suspended and fixed on the periosteum of infraorbital ridge by selected medial, middle and lateral points. The orbicularis oculi muscle was suspended and superolaterally fixed at lateral orbital periosteum. Therefore, the midface could be lifted by multi-point, multi-level suspension and fixation. Results: All incision healed in the first stage. Eyelid separation occurred to 1 patient, around 1 month after the operation. Tarsal strip lateral canthoplasty was performed for repair. Local protuberance of lateral lower eyelid occurred to another patient shortly after the operation, but improved after 3 months by lid massaging. No other complication was observed in the rest of the cases. All patients were followed up for 1 to 8 months and the results were satisfactory. Conclusions It is simple and practicable to utilize midfacial soft-tissue spaces. This method could benefit patient of less trauma, bleeding, and complications, and good clinical effect. It is a good choice for rejuvenation of the midface, especially for secondary midface rejuvenation after blepharoplasty, or complicated with lower eyelid retraction and ectropion.

Objective: To explore the clinical application of subpectoral silicone implant associated with autologous fat grafting after tissue expansion, for breast reconstructions. Methods: From Jan 2013 to Dec 2016, a total of 15 female patients were admitted to the plastic surgery department of the First Affiliated hospital of Fujian Medical University. They were after or were prepared to unilateral modified radical mastectomy. Patients were aged 18-50 years old, with the average of 33.5 years. There were 8 cases of T₁N₀M_O (T_1micN₀M_O, n=1), 3 cases of T₂N₀M_O, 1 case of T₂N₁M_O, 1 case of T₁N₂M_O, 1 case of T₂N₂M_O and 1 case of T₃N₃M_O. A tissue expander was inserted beneath the posterior pectoralis major in first surgery. The cavity stripped range is greater than the expander around 1cm. The lowest position of the expander was determined according to the IMF of the other breast. The tissue expander was gradually filled intraoperatively and postoperatively periodically, until the expander exceeds 30%-50% of the volume of the other breast. Three months later, as the soft tissue over the breast area has stretched enough, the expander was removed in a second operation and a permanent implant was inserted. Meanwhile, the autologous fat particles, harvested from thigh or abdomen, was centrifuged at 800×g for 3 minutes. Then it was injected into the subcutaneous and posterior pectoralis major space. And the other breast may be adjusted if necessary for symmetry. Results: Fifteen patients was included in this study (immediately tissue expander implanted, n=8; delayed tissue expander implanted, n=7). All the expanders are round in shape. The interval between the two operations was 6-12 months, with an average of 7.4 months. The total salt-water solution injected was 310-450 ml per patient, with an average of 365 ml. The volume of breast implants was 180-280 ml. The injection volume of autologous fat was 65-230 ml, 122.7 ml on average. All incisions healed well. The follow-up period was 1-3 years, with an average of 2 years. The reconstructed breasts were in a natural shape, with a slight drop and bilateral symmetry. According to Harris breast shape evaluation criteria, all reconstructed breasts were graded as excellent. Conclusions The permanent implant associated with autologous fat grafting after tissue expansion is alternative for breast reconstruction.

ObjectiveTo explore the value of color Doppler ultrasonography (CDU) in the differential diagnosis of cystic biliary atresia (CBA) and choledochal cyst (CC) in infants.MethodsA total of 54 infants diagnosed with hepatic portal cystic lesion in the First Affiliated Hospital of Sun Yat-sen University from January 2012 to July 2014 who were going to receive surgical treatment were included in this prospective study. Of the 54 cases, 35 were baby boys and 19 were baby girls with a mean of (63±19) d old. According to the results of pathological examination, the patients were divided into the CBA group and the CC group.All guardians of the infants signed the informed consent and the local ethical committee approval had been received. Preoperative TB level and DB level were recorded. CDU was used to observe the incidence of hepatic portal ifbrous mass, intrahepatic bile duct dilation and biliary sludge sedimentation in the cyst. In addition, the length diameter and width diameter of gallbladder and the inner diameter of hepatic artery were measured. The observed parameters of two groups were compared byχ2 test ort test.ResultsThe incidence of hepatic portal ifbrous mass in CBA group was 96% (25/26), which was signiifcantly higher than 0 (0/28) in CC group (P<0.05). The incidence of intrahepatic bile duct dilation and biliary sludge sedimentation in the cyst in CBA group were both 0 (0/26), which were signiifcantly lower than 75% (21/28) and 54% (15/28) in CC group (P<0.05). The width diameter of gallbladder in CBA group was (5±1) mm, which was signiifcantly less than (8±2) mm in CC group (t=-38.68,P<0.05). The inner diameter of hepatic artery in CBA group was (2.4±0.4) mm, which was significantly greater than (1.8±0.3) mm in CC group (t=28.40,P<0.05). ConclusionsThe hepatic portal ifbrous mass, intrahepatic bile duct dilation, biliary sludge sedimentation in the cyst, width diameter of gallbladder and inner diameter of hepatic artery are effective indexes for CDU to differentiate CBA and CC, thus, CDU may be used in the preoperative differential diagnosis.
