Objective To investigate and analyze the cognition of intraspinal labor analgesia (ILA) of women in labor and its influencing factors. Methods A total of 322 women in labor in West China Second University Hospital of Sichuan University between May and September 2015 were investigated by questionnaire, which included the general situation, the pregnancy status, the understanding for labor pain, and the cognition of ILA. Investigator introduced the knowledge of ILA to them after the investigation, and then they were re-investigated for the choice of ILA. Results Only 22.67% of these women in labor knowed ILA clearly, 53.42% heared it but did not understand, and 49.38% liked to use it. The proportion of women in labor who liked to use it increased to 81.89% after introduction, and the difference was significant (P<0.001). Among all factors, the acknowledgement level of ILA and the choice to use it were mainly related to the family awareness concept for labor pain. Conclusions The cognition of ILA of women in labor is not enough, and their using desire is not strong. The family awareness concept is one of the important factors. The education and advertise to the women in labor and their family members after admiting to labor room can increase the choice rate of ILA significantly.
Objective To provide evidence for establ ishing a health care system for pregnant women after disasters by evidence-based evaluation on the comparison of programs in different countries of the world. Methods We electronically searched The Cochrane Library (Issue 2, 2008), MEDLINE (1966 to June 2008), EMbase (1984 to June 2008), VIP ( 1989 to June 2008), CBM ( 1978 to June 2008), Wangfang database (1997 to June 2008), CNKI (1994 to June 2008) and handsearched Journals such as Chinese Journal of Obstetrics and Gynecology to identify l iteratures and guidel ines on pregnant women healthy care system after calamity. The qual ity of l iteratures and guidel ines was assessed. Results A total of 293 studies were searched, of which 25 studies were identified with the focuses on the consequence of pregnancy, development of fetus and first-aid of injuries of pregnant women. We found the studies on pregnant women’s health care were l imited, and most of them were retrospective and cohort studies, which was related to the paroxysmal ity, rarity and complexity of the disaster.? Conclusions The high proportion of pregnant women among displaced persons underscores the importance of examining how behavioral changes and difficulties in access to health care influencing the maternal and infant health, which needs comprehensive planning and arrangement.
Objective To investigate the surgical procedures and cl inical outcomes of the neurovascular free flap based on dorsal branch of digital artery of ring finger graft for repair of finger pulp defect. Methods From February 2006 to May 2009, 11 cases (11 fingers) of finger pulp defect with tendon and bone exposure were treated, including 8 males and 3 females with an average age of 29 years (range, 23-40 years). The defect locations were thumb in 2 cases, index finger in 5 cases, and middle finger in 4 cases. The defect size ranged from 1.0 cm × 1.0 cm to 2.5 cm × 2.0 cm. The time frominjury to operation was 1-9 hours. The flap size ranged from 1.5 cm × 1.5 cm to 3.0 cm × 2.5 cm. Five flaps carried the dorsal branch of digital nerve, 6 flaps carried nervi digitales dorsales. The flaps were cut from proximal radial dorsal ring finger in 4 cases and from promximal ulnar dorsal ring finger in 7 cases. Defect of donor site was repaired with full-thickness skin grafting. Results All flaps and grafted skins survived; wound and incision of donor site achieved heal ing by first intention Eleven patients were followed up 6 to 24 months with an average of 12 months. The other finger flaps had good texture and shape except for 1 flap with sl ightly bloated. The activities of finger distal interphalangeal joint were normal, the two-point discrimination of finger pulp was 7-12 mm. The extension and flexion activities of donor fingers were normal, the ringl ike thread scar left at the donor site. Conclusion It is an ideal method to use the neurovascular free flap based on dorsal branch of digital artery of ring finger graft for repair of finger pulp defect, which has the advantages of simple operation, good appearance, and functional recovery.
Tree shrew is a novel and high-quality experimental animal model. In this study, the real-time polymerase chain reaction methods were established to detect infection-related cytokines interleukin-6 (IL-6), IL-8, IL-10, IL-17A, interferon-γ (IFN-γ) and housekeeping gene glyceraldehyde-phosphate dehydrogenase (GAPDH) of tree shrew. The results indicated that the establised methods had good specificity. The high point of the linear range of these reagents reached 1 × 1010 copies, and the low points ranged from 10 copies (IL-6, IL-17A), 100 copies (IL-10, GAPDH) to 1 000 copies (IL-8, IFN-γ). In this interval, the linear correlation coefficient R2 of each reagent was greater than 0.99. The lowest detectable values of IL-6, IL-8, IL-10, IL-17A, IFN-γ and GAPDH were 8, 8, 4, 8, 128 and 4 copies, respectively. The results showed that the established detection methods had good specificity, sensitivity and wide linear range. The methods were suitable for detection of multiple concentration range samples, and could be used for the subsequent studies of tree shrew cytokines.
Objective To investigate the effectiveness of autologous nano-fat mixed granule fat transplantation in the treatment of facial soft tissue dysplasia in children with mild hemifacial microsomia (HFM). Methods A total of 24 children with Pruzansky-Kaban type Ⅰ HFM were admitted between July 2016 and December 2020. Among them, 12 children were treated with autologous nano-fat mixed granule fat (1∶1) transplantation as study group and 12 with autologous granule fat transplantation as control group. There was no significant difference in gender, age, and affected side between groups (P>0.05). The child’s face was divided into region Ⅰ(mental point-mandibular angle-oral angle), region Ⅱ (mandibular angle-earlobe-lateral border of the nasal alar-oral angle), region Ⅲ (earlobe-lateral border of the nasal alar-inner canthus-foot of ear wheel). Based on the preoperative maxillofacial CT scan+three-dimensional reconstruction data, the differences of soft tissue volume between the healthy and affected sides in the 3 regions were calculated by Mimics software to determine the amount of autologous fat extraction or grafting. The distances between mandibular angle and oral angle (mandibular angle-oral angle), between mandibular angle and outer canthus (mandibular angle-outer canthus), and between earlobe and lateral border of the nasal alar (earlobe-lateral border of the nasal alar), and the soft tissue volumes in regions Ⅰ, Ⅱ, and Ⅲ of healthy and affected sides were measured at 1 day before operation and 1 year after operation. The differences between healthy and affected sides of the above indicators were calculated as the evaluation indexes for statistical analysis. At 1 year after operation, the parents, the surgeons, and the nurses in the operation group made a self-assessment of satisfaction according to the frontal photos of the children before and after operation. Results The study group and the control group were injected with (28.61±8.59) and (29.33±8.08) mL of fat respectively, with no significant difference (t=0.204, P=0.840). After injection, 1 child in the control group had a little subcutaneous induration, and no related complications occurred in the others. All children in both groups were followed up 1 year to 1 year and 6 months, with an average of 1 year and 4 months in the study group and 1 year and 3 months in the control group. At 1 year after operation, the asymmetry of the healthy and affected sides improved in both groups; the satisfactions of parents, surgeons, and nurses in the study group were all 100% (12/12), while those of the control group were 100% (12/12), 83% (10/12), and 92% (11/12), respectively. The differences between healthy and affected sides in mandibular angle-oral angle, mandibular angle-outer canthus, earlobe-lateral border of the nasal alar, and the soft tissue volume in 3 regions of the two groups after operation were significantly smaller than those before operation (P<0.05). There was no significant difference in the above indexes between the two groups before operation (P>0.05). After operation, all indexes were significantly lower in study group than in control group (P<0.05). Conclusion Autologous nano-fat mixed granule fat transplantation and autologous granule fat transplantation can both improve the facial soft tissue dysplasia in children with mild HFM, and the former is better than the latter.
