OBJECTIVETo investigate the dynamic expression of placenta growth factor (PLGF) in the lungs with paraquat (PQ)-induced pulmonary fibrosis.

METHODSForty-two adult healthy female Sprague-Dawley (SD) rats were randomly divided into two groups: the control group and the PQ group. Each group was divided into three subgroups, seven animals each. The rats in PQ group were treated intragastrically (ig) with PQ (40 mg/kg) and the rats in control group were treated with the same volume of saline at the beginning of the experiment. The animals of model and control group were sacrificed and lungs were harvested on the 7(th), 14(th) and 28th days respectively. A semiquantitative assay of histological examination and hydroxyproline in lung tissues were used to determine the severity of alveolitis and fibrosis. RT-PCR and immunohistochemistry were used to detect the mRNA and protein expression of PLGF.

RESULTSHydroxyproline contents in lung tissue were significantly increased after PQ administration. Inflammatory cell infiltration and fibrotic scores were more prominent in the model group compared to the control group. Further study showed that PLGF mRNA on day 7, 14 and 28 (1.28 +/- 0.29, 0.80 +/- 0.07, 0.65 +/- 0.13) and positive index of protein expression (2.27 +/- 0.34, 1.78 +/- 0.41, 1.25 +/- 0.69) in the PQ group were all upregulated as compared with those of the control group.

CONCLUSIONThe PLGF expression in the lung tissue in rats with paraquat-induced pulmonary fibrosis is upregulated.

Objective:To observe the different administration methods of methoxamine on the body temperature protection of patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods:The clinical data of 278 patients underwent OPCABG from January 2019 to December 2021 in Jinzhou Central Hospital were retrospectively analyzed, and the patients were used the methoxamine during the operation. Among them, 157 cases were given methoxamine by continuous intravenous infusion (continuous intravenous infusion group), and 121 cases were given methoxamine by fractional intravenous infusion in stages (fractional intravenous infusion group). The changes of mean arterial pressure (MAP) and heart rate during operation were recorded, and the fluctuation rate of MAP was calculated. The dosage of methoxamine, use time of variable temperature blanket, time from the end of operation to waking up and occurrence of adverse reactions such as hypothermia, rigors, coagulation disorders and renal insufficiency were recorded.Results:During anesthesia, the fluctuation rate of MAP in continuous intravenous infusion group was significantly lower than that in fractional intravenous infusion group: (16.62 ± 3.17)% vs. (23.53±3.69)%, and there was statistical difference ( P<0.05). The MAP and heart rate of continuous intravenous infusion group were more stable at each time point than that of fractional intravenous infusion group. The use time of variable temperature blanket, and incidences of hypothermia, rigors in continuous intravenous infusion group were significantly lower than those in fractional intravenous infusion group: (86.17 ± 19.66) min vs. (146.72 ± 29.37) min, 2.55% (4/157) vs. 9.92% (12/121) and 1.91% (3/157) vs. 8.26% (10/121), and there was statistical difference ( P<0.01 or <0.05); there were no statistical differences in dosage of methoxamine, time from the end of operation to waking up and incidence of coagulation disorders between two groups ( P>0.05); Renal insufficiency did not occur in both groups. Conclusions:Continuous intravenous pumping of methoxamine can obviously reduce the heat loss of human body, enhance the insulation effect of other insulation measures, and reduce the incidence of hypothermia in patients underwent OPCABG.

The aim of the present study is to investigate the alterations of cardiac hemodynamics, sodium current (I(Na)) and L-type calcium current (I(Ca-L)) in the cardiomyopathic model of rats. The model of cardiomyopathy was established by intraperitoneal injection of L-thyroxine (0.5 mg/kg) for 10 d. The hemodynamics was measured with biological experimental system, and then I(Na) and I(Ca-L) were recorded by using whole cell patch clamp technique. The results showed that left ventricular systolic pressure (LVSP), left ventricular developed pressure (LVDP), +/-dp/dt(max) in cardiomyopathic group were significantly lower than those in the control group, while left ventricular end-diastolic pressure (LVEDP) in cardiomyopathic group was higher than that in the control group. Intraperitoneal injection of L-thyroxine significantly increased the current density of I(Na) [(-26.2+/-3.2) pA/pF vs (-21.1+/-6.3) pA/pF, P<0.01], shifted steady-state activation and inactivation curves negatively, and markedly prolonged the time constant of recovery from inactivation. On the other hand, the injection of L-thyroxine significantly increased the current density of I(Ca-L) [(-7.9+/-0.8) pA/pF vs (-5.4+/-0.6) pA/pF, P<0.01)], shifted steady-state activation and inactivation curves negatively, and obviously shortened the time constant of recovery from inactivation. In conclusion, the cardiac performance of cardiomyopathic rats is similar to that of rats with heart failure, in which the current density of I(Na) and especially the I(Ca-L) are enhanced, suggesting that calcium channel blockade and a decrease in Na(+) permeability of membrane may play an important role in the treatment of cardiomyopathy.

OBJECTIVETo find anatomic basis for clinically modifying technique of harvesting superior and inferior gluteal artery perforator flap, in order to avoid muscle lossing in conventional superior and inferior myocutaneous flaps, keep the advantage such as large rich supplied volume soft tissue.

METHODS5 cases 10 sides adult cadaver were used to study the numbers, position, Course of superior and inferior gluteal artery perforators. The position of perforators was located by ultrasound Doppler in 6 cases and 12 sides in patient's superior and inferior gluteal area.

RESULTSSuperior and inferior gluteal artery originated from internal iliac artery. Several main perforators of large caliber were found in the paraischia and central portions of the gluteal muscle, its number was 10 - 15. The length of the vessels varies from 3 to 8 cm and their diameter from 1 - 1.5 mm. These significant perforators pass through the muscle itself and the fascial portion of the muscle to the overlying skin on the gluteal region. The dorsal branches of nervorum lumbalium perforate the deep fascia just above the iliac crest, lateral to the posterior superior iliac spine. If a nerve branch with a substantial diameter crosses the incision line, the nerve can be harvested within the flap. This nerve can be anastomosed to the anterior ramus of the lateral branch of the 4th intercostals nerve. In adult female, 3 - 5 perforators were located by ultrasound Doppler. They distributed in the triangle area among posterior superior iliac crest, the great trochanter and the coccyx.

CONCLUSIONSThe area and diameter of perforators of superior gluteal artery were relatively confirmed. It's possible to harvest the perforator flap without any muscle. It has the advantage of conventional myocutaneous flap with out of its disadvantages. It's easy to detect those perforator by ultrasound Doppler clinically. The nerve can be harvested and anastomosed simultaneously. Because the inferior gluteal area is a weight loading area, we suggested to use superior gluteal artery perforator flap. This flap can be transferred pedicled to treat sacral pressure sores or to be transferred freely for the breast reconstruction.
