Objective To compare the surgical modes of cholecystectomy in patients with diabetes mellitus. Methods The intraoperative blood loss, operation time, duration of hospital stay and incidence of complications were respectively compared in 46 patients with diabetes receiving either laparoscopic cholecystectomy (LC, n=23) or open cholecystectomy (OC, n=23). Results In the Group LC and the Group OC, the intraoperative blood loss was (80?23) ml and (120?40) ml, respectively ( t = -4.518 , P = 0.000), the operation time was (45?20) min and (69?28) min, respectively ( t =-3.345, P =0.002), and the hospital stay was (6?2) d and (11?3) d, respectively ( t =-6.651, P =0.000). There were no statistical significances between the two groups in the incidence of complications. Conclusions LC can be performed safely in patients with diabetes mellitus. It offers the advantages over OC in less blood loss, shorter operative time and shorter hospital stay.

OBJECTIVETo apply single nucleotide polymorphism (SNP) microarray for delineation of small supernumerary marker chromosome (sSMC) in two newborns.

METHODChromosome karyotyping was performed on newborns who were born in Jan. 2013 and Jan. 2014 in Haidian Maternal and Child Health Hospital because of the abnormalities found in pregnancy checkups. SNP microarray analysis was carried out on 2 newborns with de novo sSMCs (one was mos 47,XY, + mar[45]/46,XY[5] and the other was mos 47, XY, + mar [30]/46, XY [20]), which could not be determined by conventional banding techniques. Genomic DNA was extracted from cord blood samples, amplified, tagged and hybridized following the manufacturer' s protocol. Data were collected and analyzed.

RESULTThere was a 78. 6 Mb duplication in chromosome 8 for Newborn A, which was associated with 8p22 duplication syndrome; and a 32. 7 Mb duplication in chromosome 13 for Newborn B, which was not yet reported definitely as pathogenic. The newborn A was identified with agenesis of the corpus callosum, obvious right eyelid drooping, the onset of low muscle tone and mental developmental lag behind their peers, while the newborn B had normal findings on physical and mental evaluation.

CONCLUSIONSNP-array can identify sSMCs of newborns at the DNA level, and can be used as an important supplement to the conventional karyotype analysis, but the pathogenicity of positive outputs need further verification.

Objective To investigate effect of trepibutone tablet combined with ursodeoxycholic acid in treatment of patients with gallstone. Methods 200 cases with gallstone were diagnosed and randomly divided into observation group and control group from February 2013 to February 2014.100 cases in control group were given ursodeoxycholic acid treatment 50 mg/(kg? d),two times per day for six month.On the basis of control group observation group were treated with trepibutone one tablet per day,three times per day,4 weeks for 1 course, 2 weeks of treatment interval between 4 courses, totally for four courses.After treatment, patients were followed up and recorded gallbladder wall thickness, gallbladder functional status. Results After 6 months of treatment in patients with gallbladder wall thickness of observation group ( 2.77 ±0.38 ) mm was superior to control group (3.24 ±0.36)mm(P<0.05).After 6 months of treatment in patients with gallbladder function score of observation group (58.75 ±4.79) was better than control group (53.11 ±5.02) ( P<0.05).Recurrence rate of observation group was 9% better than that of control group 18%(χ2 =3.468,P<0.05)after treatment for 6 months.Conclusion Effect of trepibutone tablet combined with ursodeoxycholic acid in treatment of patients with gallstone is well.There is no obvious side effects during the treatment.

BACKGROUND: Enophthalmos deformity is the most common complication caused by orbital blow-out fractures, and others are diplopia and worsening of visual acuity. Since the therapeutic result of orbital blow-out is not satisfactory and many complications exist after operation, it is still a dispute to select implantation materials and therapeutic regimens.OBJECTIVE: To observe the therapeutic effect and assess the improvement of visual function by surgical reconstruction with porous high-density polyethylene (Medpor) for the correction of enophthalmos deformity caused by orbital blow-out fractures.DESIGN: A pre-and postoperative controlled study.SETTING: Beauty Center for Trauma Repair,Plastic Surgery Hospital,Peking Union Medical College, Chinese Academy of Medical Science .PARTICIPANTS: Totally 56 patients with orbital blow-out fractures who had enophthalmos deformity caused by fists or traffic accidents, treated at Beauty Center for Trauma Repair,Plastic Surgery Hospital, Peking Union Medical College, Chinese Academy of Medical Science, were selected in this study from December 1996 to March 2004. Final diagnosis were made with case history, X-ray film, two-demensional and three-dimensional CT before operation. 24 cases were accompanied with other areas fractures such as zygoma and nasal bone, 34 cases with diplopia, 35 cases with visual acuity worsening after injured.METHODS: ①Material implantation: Exposure of the orbital floor, inferior and medial walls could be performed through a 2 mm inferior subciliary incision of 3 cm long. To approach the orbital rim via a dissection plane anterior to the orbital septum, sub-periosteal dissection was then performed over the orbital rim, and along the orbital floor to the orbital apex. Mobilized the soft tissue from the bone throughout the entire area of fractures and re-position it to its proper position. Took Medpor (Type 6331) sheets as the implantation materials, trimmed Medpor sheets according to the radian and anatomic form, and 2 mm larger than the defect rim was needed.If other operations were needed during the operation, they could be done.Mannitol and dexamethasone should be used just postoperatively to decrease edema of the orbital contents and reduce inner orbital excessive pressure. ②Functional evaluation standard: Diplopia: completely disappear meant recovered, less diplopia residual meant improvement, no improvement meant inefficacy. Enophthalmos: marked improvement meant the degree of enophthalmos stabilizated at below 2 mm, less improvement meant stabilizated at above 2 mm.MAIN OUTCOME MEASURES: ①Improvement of enophthalmos; ②Improvement of diplopia ; ③Improvement of visual acuity.RESULTS: ①All 56 cases of enophthalmos deformities caused by orbital blow-out fractures improved greatly. ② Of all the 34 patients with diplopia, 27 recovered. ③ 9 patients' visual acuity of 35 improved with different degrees. No diplopia or visual acuity worsening occurred. With a follow-up ranging from 2 months to 5 years, the degree of enophthalmos stabilizated at below 2 mm, and no relapse and other complications occurred.CONCLUTION: Medpor has such advantages as better histocompatibility,fewer complications and better visual function improvement, so it is the preferred implantation material for correcting enophthalmos deformity caused by orbital blow-out fractures.

Objective:To investigate frailty status of the elderly patients with leukoaraiosis (LA) and to analyze the correlation between white matter hyperintensities and their frailty status.Methods:From June 2019 to September 2020, a total of 162 patients with leukoaraiosis over 65 years old were screened by cranial MRI.The Fried frailty phenotype was used to evaluate their frailty status.The Fazekas scale scoring method was used to independently assess the periventricular white matter hyperintense (PVH) and deep white matter hyperintense (DWMH) by the cranial MRI images.SPSS 22.0 software was used for statistical analysis.ANOVA test was used to compare normal distribution data between groups, and Kruskal-Wallis H test was used to compare non-normal distribution data between groups.Spearman rank correlation analysis was used to analyze the correlation between PVH and DWMH scores and Fried frailty phenotype score. Results:Among 162 elderly patients with leukoaraiosis, 46 patients (28.40%) were non-frailty, 76 patients (46.91%)were pre-frailty and 40 patients (24.69%) were frailty.There were statistically significant differences in age( F=9.382, P<0.01), number of chronic diseases( H=10.736, P<0.01), number of medication ( H=15.927, P<0.01) and mini-nutritional assessment short form (MNA-SF) scores( F=5.263, P<0.01) among older LA patients with different frailty phenotype.There was statistical difference in PVH scores in elderly LA patients with different frailty phenotype (χ 2=108.537, P<0.01), but no significant difference in DWMH scores (χ 2=4.239, P>0.05). Spearman correlation analysis showed significant positive correlation between PVH score and frailty phenotype score in elderly LA patients ( r=0.718, P<0.001). Conclusion:Elderly LA patients have a high incidence of frailty, which may be related to aging, multi-disease coexistence, multiple medication, nutritional risk and other factors.The occurrence of weakness in elderly LA patients is related to periventricular white matter lesions, and the more serious the white matter damage, the more obvious the degree of frailty.

OBJECTIVETo study the combination of Mandibular distraction and orthognathic techniques for the reconstruction of adult hemifacial microsomia.

METHODSThe three-dimensional CT reconstruction data was used with Mimics for preoperation design. The osteotomy location, distraction vector, distraction distance were decided before operation with a surgical guider. At the first stage, internal distractor was implanted after ostetomy through an extra-oral approach. The distraction begun 5-7 days after operation with a frequency of 1 mm/day. After distraction, the distractor was maintained for 3-6 months. At the second stage, the distractor was removed. Le Fort I osteotomy was performed in order to correct the cross-bite and improve the facial contour. Usually, bone graft was inserted into the gap after Le Fort I osteotomy. The genioplasty was also performed if necessary.

RESULTS9 cases of adult hemifacial microsomia with severe mandibular deviation were treated. The facial asymmetry were improved greatly. 1 patient suffered an wound infection in the maxillary region after Le Fort I osteotomy and healed uneventfully with wound irrigation.

CONCLUSIONSMandibular distraction combined with orthognathic surgery is an effective procedure for adult hemifacial microsomia with complicated mandibular hypoplasia.

Abstract Allostatic load (AL) is related to stress. Adverse childhood experiences(ACEs), as a common stress in childhood, can make a serious and lasting impact on it. Allostatic load can reflect the wear and tear of an individual s physiological system. This article mainly reviews the functional changes of several systems of AL who have experienced ACEs, including neuroendocrine, metabolism, immune, and cardiovascular systems, as well as the different effects of the occurrence time and subtypes of ACES on AL, providing some theoretical basis for the development of early intervention plans in the future and reducing the occurrence and development of deleterious outcomes.
