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.

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 investigate the surgical management of perifolliculitis capitis abscedenset (PCAS).Methods:From June 2015 to October 2018, 8 patients with PCAS were treated, aged 13-26 years, with an average age of 23 years. Hypepigmented plaques in size were from 0.5-4.0 cm. The operative technique was based on the complete excision of the entire diseased skin and subcutaneous fatty tissue, the fistula was explored using a probe, the seton was inserted through the remaining tract in a double-strand fashion, this double-strand elastic seton was then tied over itself without excessive tension. The wound was covered with absorptive dressing.Results:All the wounds in 8 patients healed primarily. All patients were followed up for 6 months and showed no recurrence after surgery.Conclusions:Perifolliculitis capitis abscedens et suffodiens scalp is a rare chronic suppurative skin disease, its etiology and pathogenesis are unclear, but related with follicular atresia, bacterial infection, immune factors, sex hormones, smoking and obesity. The treatment is difficult, including antibiotics, vitamin A acid, biological agents, photodynamic, laser and surgery. The disease is stubborn and refractory. The technique of wide surgical excision and loose setons drainage is an effective method for PCAS.

Objective:To investigate the application value and effect of surgical removal and setons abscess drainage in moderate and severe acne inverse.Methods:A retrospective case study of 4 patients (3 males and 1 female with an average of onset of 28 years) with acne inverse at gluteal and perianal area in the Qixia Traditioal Chinese Medical Hospital of Shandong province between June 2016 and August 2020, The operative technique was based on the complete excision of the entire diseased skin and subcutaneous fatty tissue, down to the muscular fascia. The cavity was explored using a probe, two setons were placed in each of the fistula tracts, and the wound were covered with absorptive dressing.Results:All the wounds in 4 patients healed primarily and showed no recurrence after surgery, execpt for one patient who did not take supine position in time after operation which resulted in more bleeding in a short time. The other patients recovered well. The patients were followed up for 6 months without affecting the anal skin function, skin lesions and recurrence.Conclusions:The technique of wide surgical excision and setons abscess drainage is an effective method for moderate and severe acne inverse.

BACKGROUND: Calcium calmodulin-dependent kinase Ⅱ (CaMKⅡ) can be more active in patients with left ventricular hypertrophy (LVH), which in turn causes phosphorylation of ryanodine receptors, resulting in inactivation and the instability of intracellular calcium homeostasis. The present study aimed to determine the effect of CaMKⅡ–ryanodine receptor pathway signaling in rabbits with left ventricular hypertrophy and triggered ventricular arrhythmia. METHODS: Forty New Zealand rabbits were randomized into four groups (10 per group): sham group, LVH group, KN-93 group (LVH+KN-93), and ryanodine group (LVH+ryanodine). Rabbits in the LVH, KN-93, and ryanodine groups were used to establish a left ventricular hypertrophy model by the coarctation of the abdominal aorta, while those in the sham group did not undergo the coarctation. After eight weeks, action potentials (APs) were recorded simultaneously in the endocardium and epicardium, and a transmural electrocardiogram (ECG) was also recorded in the rabbit left ventricular wedge model. Drugs were administered to the animals in the KN-93 and ryanodine groups, and the frequency of triggered APs and ventricular tachycardia was recorded after the rabbits were given isoprenaline (1 mol/L) and high-frequency stimulation. RESULTS: The frequency (animals/group) of triggered APs was 0/10 in the sham group, 10/10 in the LVH group, 4/10 in the KN-93 group, and 1/10 in the ryanodine group. The frequencies of ventricular tachycardia were 0/10, 9/10, 3/10, and 1/10, respectively. The frequencies of polymorphic ventricular tachycardia or ventricular fibrillation were 0/10, 7/10, 2/10, and 1/10, respectively. The frequencies of triggered ventricular arrhythmias in the KN-93 and ryanodine groups were much lower than those in the LVH group (P<0.05). CONCLUSIONS: KN-93 and ryanodine can effectively reduce the occurrence of triggered ventricular arrhythmia in rabbits with LVH. The CaMKⅡ–ryanodine signaling pathway can be used as a new means of treating ventricular arrhythmia.

OBJECTIVETo study the efficacy of interleukin-10 (IL-10) in the treatment of experimental autoimmune prostatitis (EAP) and its effect on the expressions of tumor necrosis factor-alpha (TNF-alpha) and transforming growth factor-beta1 (TGF-beta1 ) in EAP rat models.

METHODSThirty Wistar rats were equally and randomly divided into a control, an EAP and an IL-10 group. The controls were treated with normal saline, the EAP models were made by injection of purified prostate protein twice with immune adjuvant, and the IL-10 group included the EAP models subjected to IL-10 intervention. The infiltration of the inflammatory cells of the prostate tissue was detected by HE staining, the ultrastructure of the prostate cells and their surrounding cells observed by electron microscopy, and the levels of TNF-alpha and TGF-beta1 in the three groups determined by semi-quantitative RT-PCR assay.

RESULTSThe EAP group showed significantly severer inflammation and higher levels of TNF-alpha and TGF-beta1 in the prostate tissue than the controls (P < 0.05). The IL-10 group exhibited significantly lessened inflammatory infiltration of the prostate tissue and decreased levels of TNF-alpha and TGF-beta as compared with the EAP group (P < 0.05).

CONCLUSIONIL-10 could relieve inflammatory infiltration of the prostate tissue and inhibit the expressions of TNF-alpha and TGF-beta1 in EAP rats, which is suggestive of its therapeutic efficacy for autoimmune prostatitis.

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.
