Objective To explore the influence of the intimacy and adaptability to the other fa- mily members on the postpartum recovery of parturients. Methods One hundred and twenty-two pregnant women were randomly selected among all the admissions from March to August of 2004 in the hospital. FACESⅡ-CV and (EPDS) were applied in this study. Results Postpartum depression and postpartum recovery were significantly correlated with the degree of intimacy and adaptability between the mother and other family members. Conclusions A higher degree of intimacy and adaptability in the family is helpful in postpartum recovery, breast-feeding and alleviating symptoms of postpartum depression.

Objective To investigate how to improve the survival rate,and to avoid the serious complications in fat grafting.Methods Under comprehensive design of facial filling area,the fat was harvested by concentration in mesh;under the micro autologous fat transplantation gun with blunt needle injection technique,the fat was filled into the face to achieve the effect of improving the facial contour and the rejuvenation.From June 2014 to July 2015,78 patients with facial contour and facial soft tissue relaxation depression were treatment by the technique.Results The follow-up of 2 months to 1 year showed that 64 patients had the soft,young,significantly enhanced facial contour;7 patients had second times grafts and the remaining were satisfied.7 patients gave up the second times grafts because the other reasons.The surgical complications such as facial nerve injury and infection and embolism were not seen.Conclusions This technique by comprehensive design and purification of autogenous fat granules achieves a better effect on facial rejuvenation with fewer complications.

Objective To introduce a surgical procedure resulting in less scars for unilateral microform cleft lip.Methods A Z-plasty incision was designed at suffered agger nasi,and then subcutaneours dissection of suffered upper lip and basis nasi was performed.Releasing suffered alar nasi base from maxillary bone by partly severing the mesculus compressor naris,an orbicularis oculi flap was formed and fixed to the hypodermis of columella base for advancing to superior medial position and overlaying orbicularis oculi.The labial frenulum extension and vermillion submucoustissue flap plicature for filling incisura were carried out to correct the deformitiy of vermillion incisura.Results After 6-18 months follow-up,the wounds of 7 cases (aged 7-19 years) healed at the first grade.The deformity of unilateral subcutaneous celft lip,such as the agger nasi and vermillion incisura,widened nostril,and deficient abial height,was significantly improved.Conclusions Unilateral subcutaneous celft lip could be satisfactorily reconstructed by the surgical technique consisting of Z-plasty incision at agger nasi,orbicularis oculi flap advancing,labial frenulum extension and vermillion submucous tissue flap plicature,with less scar formation.

Microglia is involved in the occurrence and development of retinal degenerative diseases,thus its activation is a marker for retinal degenerative diseases.Microglia can be activated by different external stimulating factors and polar-ized into two phenotypes with different functional states and surface markers.The classical activation pathway produces M1 phenotype microglia,which mainly exerts pro-inflammatory and neurotoxic effects;the selective activation pathway pro-duces M2 phenotype microglia,which mainly exerts anti-inflammatory and neuroprotective effects.Precise modulation of microglia polarization is a promising approach for treating retinal degenerative diseases.This paper reviews the role of mi-croglia polarization in the pathogenesis of retinal degenerative diseases,aiming to pioneer new avenues and research ideas for treating retinal degenerative diseases.

Objective To compare the long term effectiveness of tonsillotomy(TT)vs. tonsillectomy (TE)by hypercator in treatment of obstructive sleep apnea hypopnea syndrome(OSAHS)in children. Methods 119 children with tonsil hypertrophy were diagnosed with OSAHS and included in the study. Among them,57 children underwent TT by hypercator and 62 TE only after preoperative laboratory polysomnography(PSG). All participants were interviewed 5 years after operation to assess the satisfaction of their caregivers,investigate the frequency of respiratory infections,the rate of tonsil regrowth and evaluate their quality of life by Obstructive Sleep Apnea-18(OSA-18). Results Some of them received postoperative PSG. All parents reported alleviation of breathing obstruction,but the postoperative satisfaction in TT group was higher than TE group mainly because of the shorter time return to normal diet. The rate of the respiratory tract infections was not increased in all cases after surgery. Four cases of children were observed with tonsillar regrowth,but no surgery was needed for further treatment. The rate of the dry throat symptoms in TT group was lower than TE group. Conclusions Tonsillotomy by hypercator can effectively eliminate the obstruction symptoms in children with OSAHS,superior to TE for its shorter recovery period and smaller oral mucosal injury and lower rate of tonsils regrowth and it is worth to clinical promotion.

Objective:To analyze the relationship between early-life famine exposure and the risk of metabolic syndrome in Chinese population.Methods:Relevant literature on the relationship between early-life famine exposure and the risk of metabolic syndrome in the Chinese population was retrieved from databases such as CNKI, Wanfang, VIP, CBM, Web of Science, and PubMed. The search was conducted from the inception of the databases up to October 2022. Two researchers independently extracted and systematically evaluated the data from the literature, and meta-analysis was performed using Stata 16.0 software. Results:A total of 12 publications met the inclusion criteria, including 71 470 study subjects. Meta-analysis results showed that early-life famine exposure increased the risk of metabolic syndrome in the Chinese population( OR=1.28, 95% CI 1.16-1.40). Subgroup analysis showed that both fetal famine exposure( OR=1.25, 95% CI 1.03-1.52) and childhood famine exposure( OR=1.29, 95% CI 1.15-1.45) increased the risk of developing metabolic syndrome compared to the non-exposed group, and this significant association was only found in the female population. Conclusion:Early-life exposure to famine may increase the risk of developing metabolic syndrome in adulthood in the Chinese population, particularly among females.

Objective:To investigate the perinatal prognosis and its impact factors for premature infants with twin-twin transfusion syndrome (TTTS) who were born at ≤34 weeks of gestation.Methods:A retrospective study was conducted on 68 pregnancies of TTTS with gestational age ≤34 weeks at delivery, among them 106 preterm infants (TTTS group) were admitted to the neonatal intensive care unit of the First Affiliated Hospital, Sun Yat-sen University from January 2003 to February 2019. During the same period, another 178 twins without TTTS, congenital malformation, and intrauterine intervention who matched the TTTS group in maternal age (differences within two years) and gestational age (differences within one week) were assigned as non-TTTS group. Perinatal prognosis of TTTS infants born at ≤34 weeks was analyzed by comparing the differences in postnatal early complications and perinatal outcomes (survival time morn than 28 days or not) between the TTTS and non-TTTS groups, recipient and donor twins, mild and severe TTTS infants, and among TTTS infants with different intrauterine interventions. The risk factors for perinatal survival in TTTS infants with gestational age ≤34 weeks were analyzed. Two independent samples t-test, one-way analysis of variance, rank-sum test, Chi-square test, and ordered logistic regression were used for statistical analysis. Results:(1) Among the 68 pregnancies, the overall perinatal survival rate of the neonates was 72.1% (98/136), the double-twin survival rate was 48.5% (33/68), and the rate of at least one survivor was 95.6% (65/68). (2) In the TTTS group, 62 were recipients and 44 were donors. Stage Ⅰ-Ⅱ TTTS was found in 41 cases (mild TTTS group) and stage Ⅲ-Ⅴ in 65 cases (severe TTTS group). (3) The rate of severe brain injury was higher in the severe-TTTS group than those in the mild-TTTS group [9.2% (6/65) vs. 0.0% (0/41), χ 2=4.01, P=0.045]. (4) Gestational age ≤28 weeks ( OR=101.90, 95% CI: 5.07-2 048.37), stage Ⅳ ( OR=14.04, 95% CI: 1.56-126.32) and stage Ⅴ TTTS ( OR=51.09, 95% CI: 3.58-728.81) were independent risk factors for death within 28 days (all P<0.05). (5) Compared with the non-TTTS group, the TTTS group had higher rates of neonatal anemia [51.9% (55/106) vs. 33.1% (59/178), χ 2=9.71], polycythemia [5.7% (6/106) vs. 0.6% (1/178), χ 2=7.18], neonatal persistent pulmonary hypertension [3.8% (4/106) vs. 0.0% (0/178), χ 2=6.81], sepsis [15.1% (16/106) vs. 7.3% (13/178), χ 2=4.40], state Ⅲ or higher retinopathy of prematurity [3.8% (4/106) vs. 0.0% (0/178), χ 2=6.81], congenital cardiac structural abnormality [19.8% (21/106) vs. 0.6% (1/178), χ 2=33.45], heart failure [8.5% (9/106) vs. 0.6% (1/178), χ 2=12.29], and renal insufficiency [14.2% (15/106) vs. 1.1% (2/178), χ 2=20.04] (all P<0.05). Conclusions:Compared with the twin premature infants without TTTS, those with TTTS and ≤34 gestational age were more likely to have cardiac, cerebral, and renal complications. The more severe the TTTS, the higher the incidence of severe brain injury. TTTS preterm infants with gestational age ≤28 weeks and stage Ⅳ or above have high risk of death.

Objective:To investigate the changes of mortality，causes of death，and cause-specific mortality rate（CMR）of hospitalized neonates in NICU of the First Affiliated Hospital of Sun Yat-sen University.Method:A retrospective study was performed to compare the mortality，cause of death，and CMR of hospitalized neonates in period Ⅰ（2005-2009），period Ⅱ（2010-2014）and period Ⅲ（2015-2020）.Result:The overall mortality of hospitalized neonates in NICU of our hospital was 0.51%（104/20 493）through 2005 to 2020. The mortality in period Ⅰ，Ⅱ and Ⅲ were 0.61%（48/7 855），0.43%（27/6 209），and 0.45%（29/6 429），respectively. Compared with period Ⅰ，the mortality of preterm infants decreased significantly in period Ⅱ（3.14% vs 1.24%， χ2=14.076， P<0.01）and in period Ⅲ（3.14% vs 0.90%， χ2=25.157， P<0.01）. Eighty-five（81.7%）neonates were premature，and ninety-one（89.2%）neonates had definite abnormal perinatal factors. The CMR of hospitalized neonates related to pulmonary hemorrhage，congenital anomalies，and NRDS were 1.22‰（25/20 493），0.93‰（19/20 493），and 0.59‰（12/20 493），respectively. The CMR of other causes were sepsis 0.44‰（9/20 493），extremely premature 0.34‰（7/20 493），and perinatal asphyxia 0.24‰（5/20 493），respectively. Compared with period Ⅰ，specific mortality of NRDS in period Ⅱ（1.27‰ vs 0.16‰， χ2=5.487， P=0.016）and period Ⅲ（1.27‰ vs 0.16‰， χ2=5.738， P=0.014）significantly decreased. The leading causes of neonatal death in period Ⅰ，period Ⅱ，and period Ⅲ were NRDS，pulmonary hemorrhage，and congenital anomalies，respectively.And 71.2%（74/104）of neonatal deaths occurred within 7 days after birth. Conclusion:The mortality of preterm infants and specific mortality of NRDS in NICU have significantly decreased over the past 16 years.Congenital anomalies and infections remain important causes of death，and further efforts are needed to improve perinatal care.
