Epidemiology of medications use in pregnancy.
December 22, 2018, a pair of female baby twins aged 2 years with severe burns at the same time were transferred from the primary hospital to the People's Hospital of Xinjiang Uygur Autonomous Region on day 17 post burn. Physical examination on admission showed that both of them had severe burns on head, face, left upper limb, foot, etc. The blood preparations were difficult for them due to their rare blood types, with the elder sister of type B blood combined with Rh D mutant and the younger sister of type B combined with Rh negative blood. The total area of burn of the younger sister was 15% total body surface area (TBSA), with full-thickness burns with tendon and bone exposure in left ear and most of the ear auricle fallen off. The younger sister was treated with anti-infection, anti-shock by fluid infusion, and nutritional support. Split-thickness skin graft on left thigh was harvested to repair wound on left upper limb, and thin medium-thickness skin graft was harvested from right thigh in different operaization respectively. During follow-up of 6 months, the effect of the operation was good.From January 2014 to June 2018, 12 patients with skin and soft tissue defects in shoulder and elbow were admitted to General Hospital of Ningxia Medical University with skin and soft tissue defect size of 6 cm×5 cm to 11 cm×8 cm, including 9 males and 3 females aged 15-56 years. Wounds of 5 patients were repaired with rotator scapular artery perforator flap (flap area of 8 cm×7 cm to 12 cm×6 cm), and the donor flap area was sutured directly. Wounds of 3 patients were repaired with lateral thoracic perforator flap (flap area of 8 cm×7 cm to 13 cm×9 cm). The donor flap area of two patients was sutured directly, the majority of the donor flap area of one patient was sutured directly, and a small part was covered by split-thickness skin graft from ipsilateral thigh. Wounds of 4 patients were repaired with medial brachial artery perforator flap (flap area of 6 cm×5 cm to 12 cm×10 cm). The donor flap area of two patients was sutured directly, and two patients were covered with split-thickness skin graft from left chest wall. see more The flaps of 11 patients survived after surgery. Blood flow disorder at the distal end of the flap was observed in one patient. After treatment, the distal end of the flap presented 3 cm×2 cm necrosis, and the skin graft survived after second skin grafting and debridement. During the follow-up of 6 to 24 months post surgery, all patients had good texture of flap, with light scar hyperplasia in the donor flap area, and good recovery of elbow and shoulder joint function. The rotator scapular artery perforator flap, lateral thoracic perforator flap, and medial brachial artery perforator flap with the advantages being of relatively simple operation, high survival rate, and good surgical outcome, are good choices for repairing the skin and soft tissue defects in shoulder and elbow.Objective To analyze the clinical characteristics of 801 inpatients with chronic wounds. Methods The medical records of patients with chronic wounds who were admitted to the General Hospital of Southern Theater Command of PLA (hereinafter referred to as the author's unit) from January 2013 to December 2017, including gender, occupation, wound type, age, department distribution, recovery status, recovery time, hospitalization time, hospitalization cost, treatment method, clinical outcome, and medical expenses were retrospectively analyzed. Data were statistically analyzed with chi-square test, Fisher's exact probability test, and Kruskal-Wallis H test. Results Of 245 037 inpatients admitted to the author's unit within 5 years, 801 (3.3‰) patients with chronic wounds met the inclusion criteria. The composition ratio of chronic wound patients during the 5 years was 2.4‰ (106/44 230)-3.9‰ (191/49 342). Among chronic wound patients, there were 527 males and 274 females, with manual labor, retired, and unemployed p is necessary to strengthen the public knowledge about chronic wounds and improve the awareness of prevention and treatment.Objective To observe the effects of pyrroloquinoline quinine (PQQ) on the mitochondrial function and cell survival of rat bone marrow mesenchymal stem cells (BMSCs) under oxidative stress, and to explore its mechanism. Methods BMSCs of rats were cultured in vitro with Dulbecco's minimum essential medium/F12 medium containing fetal bovine serum in the volume fraction of 10% (hereinafter referred to as normal medium). The rat BMSCs of third to fifth passages in logarithmic growth phase were selected for the following experiments. (1) The cells were divided into normal control group, normal control+ PQQ group, hydrogen peroxide (H(2)O(2)) alone group, and H(2)O(2)+ PQQ group. The cells in normal control group were cultured in normal medium for 24 hours; the cells in normal control+ PQQ group were cultured in normal medium containing 100 μmol/L PQQ for 24 hours; the cells in H(2)O(2) alone group were cultured in normal medium containing 200 μmol/L H(2)O(2) for 24 hours; the cells in H(2)O(2)+ PQQ group were pre-iaved caspase-3 protein level.Objective To explore the influence of inhalation injury on fluid resuscitation of massive burn patients during shock stage. Methods A total of 74 massive burn patients (65 males and 9 females, aged 21 to 65 years) admitted to the Second Affiliated Hospital of Air Force Medical University (n=57) and Yan'an University Affiliated Hospital (n=17) from May 2009 to December 2019 were enrolled in this retrospective cohort study. Patients were divided into inhalation injury group (n=56) and non-inhalation injury group (n=18) based on clinical symptoms, vital signs, and results of bronchofibroscopy. Then 26 patients in inhalation injury group and 13 patients in non-inhalation injury group were 1∶2 matched by case-control matching based on the difference of total burn surface area. The total fluid replacement coefficient, crystalloid replacement coefficient, colloid replacement coefficient, glucose input volume, ratio of crystalloid to colloid, urine volume, and cumulative ratio of input to output volume during the first 24 h post injury, the second 24 h post injury, and the third 24 h post injury, heart rate, respiratory rate, mean arterial pressure (MAP), and hematocrit (HCT) at post injury hour (PIH) 24, 48, and 72 were recorded and compared between the two groups.
