Expression of LONP1 Is High in Visceral Adipose Tissue in Obesity, and Is Associated with Glucose and Lipid Metabolism

Background@#The nature and role of the mitochondrial stress response in adipose tissue in relation to obesity are not yet known. To determine whether the mitochondrial unfolded protein response (UPRmt) in adipose tissue is associated with obesity in humans and rodents. @*Methods@#Visceral adipose tissue (VAT) was obtained from 48 normoglycemic women who underwent surgery. Expression levels of mRNA and proteins were measured for mitochondrial chaperones, intrinsic proteases, and components of electron-transport chains. Furthermore, we systematically analyzed metabolic phenotypes with a large panel of isogenic BXD inbred mouse strains and Genotype-Tissue Expression (GTEx) data. @*Results@#In VAT, expression of mitochondrial chaperones and intrinsic proteases localized in inner and outer mitochondrial membranes was not associated with body mass index (BMI), except for the Lon protease homolog, mitochondrial, and the corresponding gene LONP1, which showed high-level expression in the VAT of overweight or obese individuals. Expression of LONP1 in VAT positively correlated with BMI. Analysis of the GTEx database revealed that elevation of LONP1 expression is associated with enhancement of genes involved in glucose and lipid metabolism in VAT. Mice with higher Lonp1 expression in adipose tissue had better systemic glucose metabolism than mice with lower Lonp1 expression. @*Conclusion@#Expression of mitochondrial LONP1, which is involved in the mitochondrial quality control stress response, was elevated in the VAT of obese individuals. In a bioinformatics analysis, high LONP1 expression in VAT was associated with enhanced glucose and lipid metabolism.

Distribution of lymphocele following lymphadenectomy in patients with gynecological malignancies

Objective@#This study identified the distribution of lymphocele, as well as the factors associated with lymphocele formation, in patients undergoing pelvic and/or para-aortic lymph node dissection (PLND and/or PALND) for gynecologic malignancies. @*Methods@#This study was retrospective, and data were collected from patients who underwent surgical procedures including lymphadenectomy due to gynecologic malignancies from March 2013 to May 2016. Lymphocele was defined by postoperative computer tomography within 2 weeks after surgery. @*Results@#A total of 116 patients underwent lymphadenectomy, of whom, 47 (42.0%) developed lymphocele and 14 (12.1%) had symptomatic lymphocele formation. The affecting factors of lymphocele formation were PLND concomitant with PALND and a large amount of blood loss ≥600 mL (P=0.030 and P=0.006, respectively). All clinical factors were not significantly different between patients with symptomatic and asymptomatic lymphocele. Lymphocele developed more frequently in the left side (67.1%) of the body compared to the right side (48.7%), and in the pelvic area (75.9%) compared to the para-aortic area (24.1%, P<0.001, both). @*Conclusion@#Lymphocele formation is more prevalent in the left and pelvic area of the body compared to the right and paraaortic side. PLND concurrent with PALND and large amounts of blood loss were significant risk factors for lymphocele formation.

Effects of laser-assisted hatching and exposure time to vitrification solution on mouse embryo development / 대한생식의학회지

OBJECTIVE: This study was conducted to investigate the efficacy of laser-assisted hatching (LAH) and various vitrification times for embryonic development and blastocyst cell numbers. METHODS: First, 2-cell and 8-cell embryos were collected by flushing out the oviducts. In the control groups, they were vitrified for 8 or 10 minutes without LAH. The LAH groups underwent quarter laser zona thinning-assisted hatching before vitrification (4, 6, and 8 minutes or 4, 7, and 10 minutes, respectively). After incubation, double-immunofluorescence staining was performed. RESULTS: The hatched blastocyst rate 72 hours after the 2-cell embryos were thawed was significantly higher in the 2LAH-ES8 group (33.3%) than in the other groups (p < 0.05). In the control-8 group (22.1±4.6), the cell number of the inner cell mass was higher than in the LAH groups (p < 0.05). The number of trophectoderm cells was higher in the 2LAH-ES6 group (92.8±8.9) than in the others (p < 0.05). The hatched blastocyst rate 48 hours after the 8-cell embryos were thawed was higher in the 8LAH-ES4 group (45.5%) than in the other groups, but not significantly. The inner cell mass cell number was highest in the 8LAH-ES7 group (19.5±5.1, p < 0.05). The number of trophectoderm cells was higher in the 8LAH-ES10 group (73.2±12.1) than in the other groups, but without statistical significance. CONCLUSION: When LAH was performed, 2-cell embryos with large blastomeres had a lower hatched blastocyst rate when the exposure to vitrification solution was shorter. Conversely, 8-cell embryos with small blastomere had a higher hatched blastocyst rate when the exposure to vitrification solution was shorter.

Recurrence factors and reproductive outcomes of laparoscopic myomectomy and minilaparotomic myomectomy for uterine leiomyomas

OBJECTIVE: The aim of this study was to determine recurrence factors and reproductive outcomes of laparoscopic myomectomy (LM) and minilaparotomic myomectomy (MM) for treating uterine leiomyomas. METHODS: Between 2007 and 2013, 160 patients underwent myomectomy, including 122 who underwent LM and 38 who underwent MM. Patients were followed up for recurrence based on pelvic ultrasound exams. Only patients who were followed up for a minimum of two years were selected for this retrospective study. Pregnancy rate, delivery, and delivery methods were compared between the two groups to evaluate reproductive outcomes. Furthermore, mean age, body mass index, preoperative administration of gonadotropin-releasing hormone agonist (GnRHa), and characteristics of leiomyomas were investigated to determine recurrence factors. RESULTS: The mean body mass index in the MM group was significantly (P=0.048) higher than that in the LM group. The number and the largest diameter of removed leiomyoma were also significantly higher in the MM group (both P=0.001). Logistic regression after adjusting significantly different characteristics showed that the LM group had shorter (P=0.020) postoperative hospitalization days compared to the MM group. Other outcome variables including recurrence rate were not significantly different between the two groups. Reproductive outcomes such as pregnancy rate, delivery, and delivery methods were not significantly different between the two groups. Preoperative GnRHa therapy was the only significant (P=0.039) recurrence factor after myomectomy. CONCLUSION: This study showed that LM and MM had similar recurrence rates and reproductive outcomes. The only recurrence factor of significance was preoperative administration of GnRHa.

Lower limb compartment syndrome by reperfusion injury after treatment of arterial thrombosis post-laparoscopic radical hysterectomy and pelvic lymph node dissection for cervical cancer

Compartment syndrome is a clinical condition associated with decreased blood circulation that can lead to swelling of tissue in limited space. Several factors including lithotomy position, prolonged surgery, intermittent pneumatic compressor, and reperfusion after treatment of arterial thrombosis may contribute to compartment syndrome. However, compartment syndrome rarely occurs after gynecologic surgery. In this case, the patient was diagnosed as compartment syndrome due to reperfusion injury after treatment of arterial thrombosis, which occurred after laparoscopic radical hysterectomy and pelvic lymph node dissection for cervical cancer. Despite its rarity, prevention and identifying the risk factors of complication should be performed perioperatively; furthermore, gynecologist should be aware of the possibility of complications.

The effect of artificial shrinkage and assisted hatching on the development of mouse blastocysts and cell number after vitrification / 대한생식의학회지

OBJECTIVE: The goal of this study was to ascertain optimal assisted hatching (AH) method in frozen embryo transfer. We compared the effect of depending on whether mechanical or laser-AH was performed before or after the vitrification of embryo development rate and blastocyst cell numbers. METHODS: In order to induce superovulation, pregnant mare's serum gonadotropin followed by human chorionic gonadotropin were injected into 4- to 5-week-old female mice. 2-cell embryos were then collected by flushing out the oviducts. The Expanded blastocysts were recovered after the collected embryos were incubated for 48 hours, and were then subjected to artificial shrinkage (AS) and cross-mechanical AH (cMAH) or quarter-laser zona thinning-AH (qLZT-AH) were carried out using the expanded blastocysts before or after vitrification. After 48 hours of incubation, followed by vitrification and thawing (V-T), and blastocysts were fluorescence stained and observed. RESULTS: The rate of formation of hatched blastocysts after 24 and 72 hours of incubation was significantly higher in the AS/qLZT-AH/V-T group than in the other groups (p<0.05). The cell number of the inner cell mass was higher in AS/V-T/non-AH and AS/V-T/cMAH groups than those of others (p<0.05). In the control group, the number of trophectoderm and the total cell number were higher than in the AS-AH group (p<0.05). CONCLUSION: The above results suggest that AS and AH in vitrification of expanded blastocysts lead to the more efficient formation of hatched blastocysts in mice.

Two pregnancy cases of uterine scar dehiscence after laparoscopic myomectomy

Uterine scar dehiscence following laparoscopic myomectomy rarely occurs but can compromise both maternal and fetal well-being in subsequent pregnancy. We here present two cases of pregnancy complicated by preterm birth that resulted from uterine scar dehiscence following laparoscopic myomectomy. First case was a nulligravida who had scar dehiscence at 26 weeks of gestation after having a laparoscopic myomectomy 3 months prior to conception. Two weeks later, we observed her fetal leg protruding through the defect. The other case was a primigravida with a history of prior cesarean delivery, whose sonography revealed myomectomy scar dehiscence at 31 weeks of gestation. Within a few hours after observing, the patient complained of abdominal pain that was aggravating as fetal leg protruded through the defect. In both cases, babies were born by emergency cesarean section. Conservative management can be one of treatment options for myomectomy scar dehiscence in preterm pregnancy. However, clinicians should always be aware of the possibility of obstetric emergencies.

Laparoscopic assisted adenomyomectomy using double flap method

OBJECTIVE: The purpose of this study was to evaluate postoperative prognosis and progression in patients who received laparoscopic-assisted adenomyomectomy using the double flap method. METHODS: The pelvic cavity was explored by the conventional laparoscopic method, and drainage was achieved through a 5-mm trocar. After a small incision in the abdomen, the uterus was incised from the fundus to the upper cervical margin until exposing the endometrial cavity. Adenomyotic tissue was removed using a scalpel, scissors, or monopolar electrical bovie. The endometrial cavity was repaired with interrupted sutures using 2-0 vicryl. One side of the serosal flap was used to cover the endometrial side of the uterus. The second serosal flap covered the first flap after removal of the serosal surface of the first flap. RESULTS: From January 2008 to March 2012, there were 11 cases of laparoscopic-assisted adenomyomectomy at Chungnam National University Hospital. Nine cases were analyzed, excluding two cases with less than one year of follow-up. The average patient age was 37.0 years and average follow-up duration was 32.8 months. All patients showed improvement in dysmenorrhea (P < 0.001) and hypermenorrhea (P = 0.001) after surgery and were evaluated by visual analogue scale score. However, symptoms of adenomyosis were aggravated in three patients. Adenomyosis was progressed in the side opposite the site of operation. One patient required a total laparoscopic hysterectomy 27 months after surgery. CONCLUSION: Laparoscopic-assisted adenomyomectomy using the double flap method is effective for uterine reduction and relief of dysmenorrhea and hypermenorrhea. Conservative management and careful follow-up are needed because adenomyosis can recur or progress in some patients.

Two-port access versus four-port access laparoscopic ovarian cystectomy

OBJECTIVE: This study was conducted to compare the surgical outcomes between two-port access and four-port access laparoscopic ovarian cystectomy. METHODS: Four hundred and eighty nine patients who had received two-port access laparoscopic ovarian cystectomy (n=175) and four-port access laparoscopic ovarian cystectomy (n=314) in Chungnam National University Hospital from January 2009 to August 2012 were analyzed retrospectively. The data were compared between the bilaterality of the cysts and cyst diameter of less than 6 cm and 6 cm or more. RESULTS: There were no significant differences in patient's age, parity, body weight, body mass index and history of previous surgery between the two-port and four-port access laparoscopy group. Bilaterality of ovarian cysts was more in fourport access laparoscopy group (13.7% vs. 32.5%, P=0.000). There were no significant differences in operation time, hemoglobin change, hospital stay, adhesiolysis, transfusion, and insertion of hemo-vac between the two-port and four-port access laparoscopy group for size matched compare. However additional analgesics were more in four-port access laparoscopy group for unilateral ovarian cystectomy. CONCLUSION: Two-port access laparoscopic surgery was feasible and safe for unilateral and bilateral ovarian cystectomy compare with four-port access laparoscopic surgery.

The influence of serum substituents on serum-free Vero cell conditioned culture media manufactured from Dulbecco's modified Eagle medium in mouse embryo culture

OBJECTIVE: This study was conducted to examine the influences of supplementation of the serum substituents and available period of serum-free Vero cell conditioned media (SF-VCM) manufactured from Dulbecco's modified Eagle medium cultured with Vero cells for in vitro development of mouse preimplantation embryos. METHODS: A total of 1,099 two-cell embryos collected from imprinting control region mice were cultured in SF-VCM with 10% and 20% human follicular fluid (hFF), serum substitute supplement (SSS), and serum protein substitute (SPS). Development of embryos was observed every 24 hours. Results between different groups were analyzed by chi-square test, and considered statistically significant when P-value was less than 0.05. RESULTS: The rates of embryonic development cultured in SF-VCM supplemented with serum substituents were significantly higher compare with serum-free group (P < 0.05). The rates of embryonic development after 48 hours (morula< or =) and 96 hours (blastocyst< or =) were significantly higher in 20% SSS and 10% SPS than in 20% hFF supplementation (P < 0.05). And the rates of embryonic development after 96 hours (hatching blastocyst< or =) were significantly higher in 10% SPS (94.5%) than in 20% SSS (82.6%) and 20% hFF supplementation (68.5%). The rates of embryonic development according to storage period of the SF-VCM supplemented with 10% SPS showed no significant difference between control, 2 weeks and 4 weeks group. However developmental rate in 6 weeks storage group was significantly lower than other groups. CONCLUSION: The rate of embryonic development after 96 hours (hatching blastocyst< or =) was significantly higher in SF-VCM supplemented with 10% SPS. And storage period of media up to 4 weeks did not affect on embryonic development.

Meconium peritonitis: prenatal diagnosis and postnatal outcome / 대한산부인과학회지

OBJECTIVE: To detect meconium peritonitis for the fetal period is important for prenatal counseling. The aim of this study was to evaluate prenatal ultrasound finding for diagnosing meconium peritonitis and postnatal clinical course and outcomes. METHODS: The prenatal and postnatal medical records of all patients to our institutions with confirmed meconium peritonitis were reviewed, with emphasis on prenatal ultrasound findings, postnatal investigations, operative findings, outcomes of meconium peritonitis. RESULTS: Fourteen fetuses were confirmed to have meconium peritonitis at birth by operation. Eight cases were diagnosed correctly because of prenatal ultrasound showing ascites and calcification/dilated or hyperechoic bowel loops. In the other 6 cases, prenatal ultrasound showed only ascites. One patient was operated on first day of life and its intra-operative finding was malrotation of small bowel, volvulus with strangulation, perforation and jejunal atresia. Most cases were operated on 2nd or 3rd day of life. Intra-operative findings were ileal atresia and perforation in 11 cases and jejunal atresia and perforation in 3 cases. Four patients underwent ileostomy but all patients survived and prospered. CONCLUSION: All patients do not present typical prenatal ultrasound findings of meconium peritonitis. Therefore, even in pregnancies associated with isolated ascites, meconium peritonitis should be taken into consideration. Favorable outcome of intrauterine meconium peritonitis is reassuring in prenatal counselling and stems from multidisplinary team approach.

Studies on development of serum-free conditioned media using Vero cells and DMEM with controlled concentration of glucose and pyruvate / 대한산부인과학회지

OBJECTIVE: The purpose of this study was to examine in vitro development of early preimplantation mouse embryos in various kind of serum-free conditioned media (SF-VCM) manufactured from DMEM cultured with Vero Cells. METHODS: A total of 846 two-cell mouse embryos were cultured in different kind of SF-VCM. SF-VCMs were divided into SF-VCM-10, -30 and -50 by media volume using DMEM #1 media, and divided into SF-VCM #1, #2 and #3 by controlled concentration of glucose and pyruvate (manufactured by DMEM #1: mixed three volume of DMEM-G (DMEM with glutamine without glucose and pyruvate) and one volume of DMEM-GGP (DMEM with glutamine, glucose, pyruvate), #2: mixed same volume of DMEM-G and DMEM-GGP and #3: mixed one volume of DMEM-G and three volume of DMEM-GGP, respectively). Experimental groups were mainly added 10% SSS, and 20% hFF was added to only Control group co-cultured with Vero cells. Development of embryos was observed every 24 hours. Results between different groups were analyzed using Chi-square test, and considered statistically significant when P-value was less than 0.05. RESULTS: In vitro developmental rate by each cleavage stages of mouse embryos cultured in SF-VCMs with a various volumes were significantly (P<0.05) higher in SF-VCM-30 (morula< or =: 97.2%, Blastocyst (BL)< or =: 97.2%, Hatching BL< or =: 82.2%) than other groups. In the rate of development on in vitro co-culture vs. a various SF-VCMs manufactured by DMEM controlled concentration of glucose and pyruvate, Group I (SF-VCM #1) was higher than other groups in each cleavage stages (morula< or =: 98.1%, Blastocyst (BL)< or =: 97.1%, hatching BL< or =: 81.7%, respectively). Moreover, specially, in the developmental rate into the hatching blastocyst < or = after 96 hours in vitro culture, Group I (81.7%) was significantly higher than control group (67.6%, P<0.05). CONCLUSION: SF-VCM #1 manufactured by volume of 30 mL DMEM #1 media cultured in vitro for 48 hours in 250 mL flask was the most effective on in vitro developmental rate of mouse preimplantation embryos. Therefore, it is expected that SF-VCM #1 has application to human IVF-ET.

One case of vulva metastasis from cervical squamous cell carcinoma / 대한산부인과학회지

Metastasis to the skin occurs rarely in gynecologic cancer. Although carcinoma of the cervix is the fifth most common malignancy in Korean women, cutaneous involvement originating from cervical cancer is unusual. Common pattern of occurrence is multiple nodule in abdomen, vulva, lower extremities. We report a case of metastasis from squamous cell carcinoma of cervix to vulva. The patient was diagnosed with cervical cancer IIA. The extensive skin lesion on the vulva occurred 3 months after neoadjuvant chemotherapy, radical hysterectomy and concurrent chemoradiation. We have experienced such a case and report the case with brief review of literatures.

Six cases of laparoscopic assisted neovaginoplasty using pelvic peritoneal flap in MRKH syndrome / 대한산부인과학회지

Vaginal agenesis is rare gynecologic condition, and the most common etiology is Mayer-Rokitansky-Kster-Hauser (MRKH) syndrome, characterized by the absence of uterus and vagina and presence of normal ovaries and tubes. In such patients, the evaluation for associated malformations as well as careful non-surgical and surgical approach are essential. The neovaginoplasty is an important issue for these patients in regard of functional and psychological standpoint. There are many options available for creation of neovagina. We report six cases of laparoscopic assisted neovaginoplasty using pelvic peritoneal flap.

Laparoscopic repair of vesicovaginal fistula / 대한산부인과학회지

Vesicovaginal fistula (VVF) is one of the most serious surgical complication in gynecologic surgery. Surgical approach to repair this condition can be performed by transvaginal or transabdominal. However, laparoscopic repair of VVF may be an alternative surgical method. We present four cases of VVF treated with transperitoneal laparoscopic technique. Laparoscopic repair is a feasible, safe and efficacious minimally invasive approach for the management of VVF. We believe that this method provides excellent results and may result in lower morbidity, shorter hospital stay, and quicker recovery than the abdominal or transvaginal approaches.

Transcriptional profiling in human HaCaT keratinocytes in response to kaempferol and identification of potential transcription factors for regulating differential gene expression

Kaempferol is the major flavonol in green tea and exhibits many biomedically useful properties such as antioxidative, cytoprotective and anti-apoptotic activities. To elucidate its effects on the skin, we investigated the transcriptional profiles of kaempferol-treated HaCaT cells using cDNA microarray analysis and identified 147 transcripts that exhibited significant changes in expression. Of these, 18 were up-regulated and 129 were down-regulated. These transcripts were then classified into 12 categories according to their functional roles: cell adhesion/cytoskeleton, cell cycle, redox homeostasis, immune/defense responses, metabolism, protein biosynthesis/modification, intracellular transport, RNA processing, DNA modification/ replication, regulation of transcription, signal transduction and transport. We then analyzed the promoter sequences of differentially-regulated genes and identified over-represented regulatory sites and candidate transcription factors (TFs) for gene regulation by kaempferol. These included c-REL, SAP-1, Ahr-ARNT, Nrf-2, Elk-1, SPI-B, NF-kappaB and p65. In addition, we validated the microarray results and promoter analyses using conventional methods such as real-time PCR and ELISA-based transcription factor assay. Our microarray analysis has provided useful information for determining the genetic regulatory network affected by kaempferol, and this approach will be useful for elucidating gene-phytochemical interactions.

Clinical Features of Ophthalmic Artery Hypoperfusion

PURPOSE: The purpose of the study is to investigate the clinical features and relation of systemic disease of ophthalmic artery hypoperfusion (OAH). METHODS: We reviewed the records of 20 eyes of 19 ophthalmic artery hypoperfusionpatients who were followed up for 1month or more. The clinical outcome were reviewed, retrospectively. RESULTS: The patients' chief complain was sudden visual loss (14 eyes, 70.0%) and at initial visit, eyes with OAH had mean visual acuity more than or equal 0.5 in 55.0%. The most common ocular sign is the retinal hemorrhage and choroidal infarction and the most associated systemic disease in these patients is the hypertension in 63.2%. Normal patency or mild changes of the internal carotid artery was seen in 75.0% on the side of OAH. CONCLUSIONS: Ophthalmic artery hypoperfusion has a comparatively good visual prognosis. However, the ophthalmologist's diagnosis may be crucial to the health of these patients, because OAH includes ocular ischemic syndrome that may be the presenting sign of serious cerebrovascular and ischemic heart disease.

Three cases of vaginal evisceration after laparoscopic hysterectomy / 대한산부인과학회지

Vaginal evisceration is a rare but life threatening complication of gynecologic surgery. Most of them occur after abdominal or vaginal hysterectomy. The incidence after laparoscopic hysterectomy is unknown. The incidence of evisceration in the patients undergoing laparoscopic hysterectomy in our hospital was 0.1 %. The rapid recovery after laparoscopic hysterectomy, compared with abdominal hysterectomy, is widely acknowledged. Swift return to everyday activities and early resumption of intercourse could predispose to rupture of vaginal vault. Upon discharge, patients undergoing laparoscopic hysterectomy should be given careful instructions to avoid coitus until complete healing of vaginal vault. We described three cases of vaginal evisceration after laparoscopic hysterectomy including a review of the literature.
