This study aimed to investigate the relationship between the promoting effect of Zuogui Pills on ovarian and vaginal angiogenesis in early-aging rats and mobilization factors granulocyte-macrophage colony-stimulating factor(GM-CSF), stromal cell-derived factor-1(SDF-1), and their receptors of endothelial progenitor cells(EPCs) and explore the mechanism of Zuogui Pills in improving reproductive hypofunction in early-aging rats. Ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS) was used to analyze the chemical components of the extract of Zuogui Pills. Forty 14-month-old female early-aging rats with estrous cycle disorder were randomly divided into a blank group, a conjugated estrogen group(conjugated estrogen suspension, 65 μg·kg~(-1)), and low-(11 g·kg~(-1)) and high-dose(33 g·kg~(-1)) Zuogui Pills groups, with 10 rats in each group. In addition, 10 4-month-old female rats were assigned to the youth control group. The rats in the blank group and the youth control group were treated with 20 g·kg~(-1) distilled water by gavage, while those in the groups with drug intervention were treated with corresponding drugs by gavage, once a day for 15 days. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of SDF-1 and GM-CSF in the mobilization of EPCs in serum. Hematoxylin-eosin(HE) staining was used to observe the changes in the number of ovarian follicles at all levels and corpus luteum, the number of vaginal epithelial layers, the number of vaginal folds, and the blood vessels of ovarian and vaginal tissues in the groups with drug intervention. Western blot was used to detect the expression of ER, GM-CSFR, CXCR4, and CXCR7 proteins in ovarian and vaginal tissues. As revealed by the results, the blank group showed decreased number of corpus luteum, gro-wing follicles at all levels, and blood vessels(P<0.05), decreased thickness of vaginal mucosa, the number of epithelial layers, the number of vaginal folds, and the number of vessels in the lamina propria(P<0.05), reduced content of SDF-1 and GM-CSF in the peripheral blood(P<0.05), and down-regulated levels of ER, CXCR4, CXCR7, and GM-CSFR proteins in ovarian and vaginal tissues(P<0.05). The groups with drug intervention showed increased number of growing follicles at all levels, corpus luteum, and blood vessels(P<0.05), decreased number of atresia follicles(P<0.05), increased thickness of vaginal mucosa, the number of epithelial layers, the number of vaginal mucosal folds, and the number of blood vessels in the lamina propria(P<0.05), increased content of SDF-1 and GM-CSF in the peripheral blood(P<0.05), and up-regulated levels of ER, CXCR4, CXCR7, and GM-CSFR proteins in ovarian and vaginal tissues(P<0.05). This experiment suggests that Zuogui Pills may promote ovarian and vaginal angiogenesis and improve the reproductive function of early-aging rats by up-regulating the levels of mobilization factors SDF-1, GM-CSF, and their receptors of EPCs.

This commentary is focused primarily on the relationship between menopausal hormone therapy (MHT) and breast cancer risk, the primary adverse outcome measure of the Women’s Health Initiative (WHI) hormone trials. The WHI hormone trials are to date the largest randomized, placebo-controlled studies that evaluated the risks and benefits of hormone therapy in postmenopausal women. There are two arms: the estrogen-progestin (conjugated equine estrogen/medroxyprogesterone acetate) arm for women with intact uterus and the estrogen-alone (conjugated equine estrogen) arm for women who had a hysterectomy1. Both arms, planned to continue for 8.5 years, were stopped prematurely, the CEE/MPA arm after a mean of 5.2 years of follow-up and the CEE-alone arm after a mean of 7.2 years follow-up.

BACKGROUND: Motorcycles are one of the important members of commercial transportation because of the convenient use during congested traffic conditions and the ease of parking in narrow streets. This study investigates the characteristics of crashes and traffic signal violations caused by motorcycle couriers. METHODS: From the national compensation data, this study analyzed the traffic crashes caused by 671 motorcycle couriers. RESULTS: Among 671 injured couriers, 50.6% were aged less than 40 years, 49.2% run in a small business of < 5 employees, and 47.2% had work experience of < 6 months. Motorcycle crashes occurred mainly due to “rider overturned alone” (67.5%), in the daytime (73.5%), or on cloudy or clear days (77.2%). However, the violation rate caused by motorcycle couriers was high in couriers in a small business of < 5 employees (13.9%), with work experience of < 6 months (13.9%), on cloudy or clear days (12.4%), on an intersection (29.8%), in the type of “crash with a vehicle” (31.2%), or in a death accident (35.7%). CONCLUSION: The findings of this study can be used as a baseline in devising policies for preventing crashes of motorcycle couriers.

The pathogenesis of cerebral malaria is biologically complex and involves multi-factorial mechanisms such as microvascular congestion, immunopathology by the pro-inflammatory cytokine and endothelial dysfunction. Recent data have suggested that a pleiotropic T-cell immunomodulatory protein (TIP) could effectively mediate inflammatory cytokines of mammalian immune response against acute graft-versus-host disease in animal models. In this study, we identified a conserved homologue of TIP in Plasmodium berghei (PbTIP) as a membrane protein in Plasmodium asexual stage. Compared with PBS control group, the pathology of experimental cerebral malaria (ECM) in rPbTIP intravenous injection (i.v.) group was alleviated by the downregulation of pro-inflammatory responses, and rPbTIP i.v. group elicited an expansion of regulatory T-cell response. Therefore, rPbTIP i.v. group displayed less severe brain pathology and feverish mice in rPbTIP i.v. group died from ECM. This study suggested that PbTIP may be a novel promising target to alleviate the severity of ECM.

5.Use of the cross-leg distally based sural artery flap for the reconstruction of complex lower extremity defects
Archives of Plastic Surgery 2019;46(3):255-261
Cross-leg flaps are a useful reconstructive option for complex lower limb defects when free flaps cannot be performed owing to vessel damage. We describe the use of the extended distally based sural artery flap in a cross-leg fashion for lower extremity coverage in three patients. To maximise the viability of these extended flaps, a delay was performed by raising them in a bipedicled fashion before gradual division of the tip over 5 to 7 days for cross-leg transfer. Rigid coupling of the lower limbs with external fixators was critical in preventing flap avulsion and to promote neovascular takeover. The pedicle was gradually divided over the ensuing 7 to 14 days before full flap inset and removal of the external fixators. In all three patients, the flaps survived with no complications and successful coverage of the critical defect was achieved. One patient developed a grade 2 pressure injury on his heel that resolved with conservative dressings. The donor sites and external fixator pin wounds healed well, with no functional morbidity. The cross-leg extended distally based sural artery flap is a reliable reconstructive option in challenging scenarios. Adequate flap delay, manoeuvres to reduce congestion, and postoperative rigid immobilization are key to a successful outcome.

Renal cortical necrosis (RCN) is patchy or diffuse ischemic destruction of the renal cortex caused by significantly reduced renal arterial perfusion. It is a rare cause of acute kidney injury (AKI) and is associated with high mortality. Here, we review the case of RCN in a 15-year-old boy who developed AKI. A 15-year-old boy was referred to our hospital from a local hospital due to a sharp decrease in his renal function. He presented with acute flank pain, nausea with vomiting, and oliguria for the past two days. He had taken a single dose of antihistamine for nasal congestion. At our hospital, his peak blood pressure was 148/83 mmHg and he had a high body mass index of 32.9 kg/m². The laboratory data showed a blood urea nitrogen (BUN) of 28.4 mg/dL, a creatinine of 4.26 mg/dL, and a glomerular filtration rate estimated from the serum cystatin C of 20.2 mL/min/1.73m². Proteinuria (spot urine protein to creatinine ratio 1.66) with pyuria was observed. Kidney sonography showed parenchymal swelling and increased renal echogenicity. Due to rapidly progressing nephritis, steroid pulse therapy (750 mg/IV) was done on the second day of his admission and the patient showed complete recovery with normal renal function. However, the kidney biopsy findings revealed renal cortical hemorrhagic necrosis. Multifocal, relatively well-circumscribed, hemorrhagic necrotic areas (about 25%) were detected in the tubulointerstitium. Although RCN is an unusual cause of AKI, especially in children, pediatricians should consider the possibility of RCN when evaluating patients with rapidly decreasing renal function.

Sinus histiocytosis with massive lymphadenopathy, also known as Rosai-Dorfman disease (RDD), is a rare histiocytic disorder of unknown etiology. Most patients with RDD have spontaneous remission, but in some patients, the disease recurs after complete remission and may not respond to general treatment. Some patients with RDD involving the extranodal system can have serious symptoms such as vital organ dysfunction due to mass effects, neurological symptoms caused by intracranial involvement, and respiratory distress with airway involvement. We report the case of a 7-year-old girl with severe dyspnea due to refractory extranodal RDD that caused progressive upper airway obstruction. She was admitted because of nasal congestion and persistent cervical lymphadenopathy, and diagnosed as having RDD by cervical lymph node incisional biopsy. The initial prednisone treatment did not improve her symptoms. The following contrast-enhanced neck computed tomography revealed a newly developed airway mass protruding in the upper trachea. After 8 weeks of chemotherapy with vinblastine, methotrexate, and prednisone, complete remission was attained. Seven months after chemotherapy cessation, the disease recurred, and chemotherapy with vincristine, cytarabine, and prednisone was resumed. Despite the chemotherapy and emergency radiotherapy, no improvement was observed in the cervical lymph node enlargement and airway obstructive symptom due to the upper tracheal mass. 2-Chlorodeoxyadenosine (cladribine) therapy was initiated, and the patient got complete remission after 6 cycles of the cladribine treatment and maintained no evidence of disease for 2 years. We suggest that cladribine is an effective treatment option for recurrent/refractory RDD.

OBJECTIVE: We attempted to discover that Ankylosing spondylitis (AS) has a comprehensive relationship with congestive heart failure and death.METHODS: We used a nationwide database managed by the Korean National Health Insurance Service from 2010 to 2014. Twelve thousand nine hundred eighty-eight patients with a diagnosis of AS and 64940 age- and sex- stratified matching subjects without AS were enrolled in the AS and control groups. Incidence probabilities of 6 years congestive heart failure and death in each group were calculated. The Cox proportional hazard regression analysis was used to estimate the hazard ratio. We divided the AS and control groups into subgroups according to sex, age, income, and comorbidities.RESULTS: During the follow-up period, 102 patients (0.79%) in the AS group and 201 patients (0.32%) in the control group developed congestive heart failure (p < ;0.0001). In addition, 211 (1.62%) subjects in the AS group died during the follow-up period compared to 639 (0.98%) subjects in the control group (p < ;0.0001). The adjusted hazard ratio of congestive heart failure and death in the AS group was 2.28 (95% confidence interval [CI], 1.80–2.89) and 1.66 (95% CI, 1.42–1.95), respectively. The hazard ratios of congestive heart failure and death were significantly increased in all of the subgroups.CONCLUSION: The incidence rates of congestive heart failure and death were increased in AS patients.

Journal of the Korean Ophthalmological Society 2019;60(4):387-392
PURPOSE: We report two cases of intraocular lens (IOL) pupillary optic capture following IOL scleral fixation treated with argon laser iridotomy. CASE SUMMARY: (Case 1) A 69-year-old man presented with suddenly decreased visual acuity of the left eye. The best-corrected visual acuity was finger count (FC) 30 cm in the left eye. Slit lamp examination revealed subluxation of the left eye IOL. An IOL scleral fixation and anterior vitrectomy were performed and no specific findings were observed. During the follow-up period, pupillary optic capture was repeated without specific causes, such as trauma, or IOL decentration thus, argon laser iridotomy was performed. (Case 2) A 77-year-old man presented with a 3-day history of congestion of the left eye and decreased visual acuity. Best-corrected visual acuity was 0.4 logarithm of the minimum angle of resolution (logMAR) in the left eye. Slit lamp examination revealed subluxation of the left eye IOL. An IOL scleral fixation and anterior vitrectomy were performed, and no specific findings were observed. During the follow-up period, pupillary optic capture was found, and IOL repositioning and argon laser iridotomy were performed. CONCLUSIONS: Laser iridotomy can be used to prevent recurrence of pupillary optic capture in eyes with IOL scleral fixation without decentration or distortion.

Journal of the Korean Ophthalmological Society 2019;60(4):369-373
PURPOSE: When there is a mass in the superior temporal orbit area, a lacrimal gland tumor should be suspected. We report a rare case of orbital lymphatic malformation that was histologically diagnosed in a patient with typical clinical features of the lacrimal gland. CASE SUMMARY: A 55-year-old female with no underlying disease and no ophthalmic history visited our clinic with a right upper eyelid edema associated with an enlarged painless eyelid mass 1 month prior to her visit. The patient stated that she discovered the mass 1 year previously.The palpebral lobe of the lacrimal gland protruded slightly with congestion of the surrounding conjunctiva. Enhanced computed tomography showed a 3 cm well-defined heterogeneous mass in the right lacrimal gland area and several well-defined round calcifications within the mass. Orbital tissue or bone involvement was not observed. The pleomorphic adenoma of the lacrimal gland was the most clinically suspicious, so complete resection of the mass was performed using lateral orbitotomy. Histopathologically, lymphangioma (lymphatic malformation) originating from the lacrimal gland was diagnosed. CONCLUSIONS: Orbital lymphatic malformation can occur in the lacrimal gland. The present case showed that differential diagnosis can reveal the presence of an adult lacrimal gland tumor.
