Clinical efficacy of acupuncture combined with Chinese herbal medication for recurrent implantation failure infertility of kidney deficiency and blood stasis and its effects on serum p38MAPK and JAK/STAT protein expression / 中国针灸

OBJECTIVES@#To observe the effects of acupuncture combined with Chinese herbal medication on pregnancy outcomes in patients with recurrent implantation failure (RIF) infertility of kidney deficiency and blood stasis, and to explore its effects on the protein expression of serum p38MAPK and JAK/STAT.@*METHODS@#Sixty-two patients with RIF infertility of kidney deficiency and blood stasis who were scheduled for artificial cycle frozen-thawed embryo transfer were randomly divided into an observation group (31 cases, 4 cases dropped out) and a control group (31 cases, 3 cases were eliminated). The patients in the control group were treated with conventional artificial cycle frozen-thawed embryo transfer. On the basis of the control group, the patients in the observation group were treated with acupuncture combined with Chinese herbal medication. Acupuncture was applied at Baihui (GV 20), Guanyuan (CV 4) and bilateral Neiguan (PC 6), Zigong (EX-CA 1), Guilai (ST 29), Zusanli (ST 36), Taichong (LR 3), Shenshu (BL 23), Ciliao (BL 32), with each session lasting for 30 minutes, once every other day. Chinese herbal medication was administered to Bushen Huoxue (tonifing the kidney and activating blood circulation) decoction, with one dose per day, starting from the 3rd to 5th day of the menstrual cycle and continuing until 1 day before embryo transfer. Clinical pregnancy rate, embryo implantation rate, live birth rate, and biochemical pregnancy rate were compared between the two groups. TCM symptom score, platelet count (PLT), and plasma D-dimer level were assessed before treatment and 1 day before embryo transfer. Western blot method was used to detect the expression of serum P38MAPK, JAK, and STAT proteins before treatment and 1 day before embryo transfer.@*RESULTS@#In the observation group, the clinical pregnancy rate, embryo implantation rate, and live birth rate were higher (P<0.05), while the biochemical pregnancy rate was lower (P<0.05) than those in the control group. One day before embryo transfer, both groups showed a decrease in TCM symptom scores, PLT, and plasma D-dimer levels compared to those before treatment (P<0.05), and the observation group had lower TCM symptom scores and plasma D-dimer levels than the control group (P<0.05). One day before embryo transfer, the expression levels of serum p38MAPK, JAK, and STAT proteins in both groups were lower than those before treatment (P<0.05), and the observation group had lower serum p38MAPK protein expression than the control group (P<0.05).@*CONCLUSIONS@#Acupuncture combined with Chinese herbal medication can improve the clinical pregnancy rate, embryo implantation rate, live birth rate, and reduce the biochemical pregnancy rate in RIF infertility patients of kidney deficiency and blood stasis. Its mechanism of action may be related to down-regulating plasma D-dimer level and protein expression of serum p38MAPK.

Effects of auricular thumbtack needle on lactation function and TDP-43/Btn1A1/XDH pathway in primiparous women with cesarean section / 中国针灸

OBJECTIVE@#To observe the effects of auricular thumbtack needle on breast feeding and lactation function in primiparous women with cesarean section, and to explore its mechanism of action from the perspective of lactation-related gene expression.@*METHODS@#One hundred cases of primiparous women with cesarean section were randomly divided into an observation group (50 cases, 3 cases dropped off) and a control group (50 cases, 2 cases were eliminated). The patients in the control group were treated with routine obstetric care. Based on the treatment of the control group, the patients in the observation group were treated with auricular thumbtack needle at Neifenmi (CO18), Xiong (AH10), Xiongzhui (AH11), Shenmen (TF4), and Jiaogan (AH6a), etc., with one side of auricular point selected, only once for a total of 3 d. The lactation initiation time, lactation adequacy rate at postpartum 72 h, exclusive breastfeeding rate at postpartum 42 d, and breastfeeding score after treatment were compared between the two groups. Real-time quantitative PCR and Western blot method were used to detect the mRNA and protein expression levels of TDP-43, Btn1A1 and XDH.@*RESULTS@#After treatment, the lactation initiation time in the observation group was earlier than that in the control group (P<0.01), and breastfeeding score in the observation group was higher than that in the control group (P<0.01). The lactation adequacy rate at postpartum 72 h was 63.8% (30/47) in the observation group, which was higher than 41.7% (20/48) in the control group (P<0.05). The exclusive breastfeeding rate at postpartum 42 d was 72.3% (34/47) in the observation group, which was higher than 47.9% (23/48) in the control group (P<0.05). The mRNA and protein expression levels of TDP-43 and Btn1A1 in breast milk in the observation group were higher than those in the control group (P<0.01), while there was no statistically significant difference in mRNA and protein expression of XDH in breast milk between the two groups (P>0.05).@*CONCLUSION@#The auricular thumbtack needle in addition to routine care could promote lactation initiation, improve lactation adequacy rate and exclusive breastfeeding rate in primiparous women with cesarean section, and the action mechanism may be related to up-regulation of TDP-43 and Btn1A1 expression.

Effect of Diabetes Mellitus on Symptomatic Improvement After Surgery for Benign Prostatic Hyperplasia in Patients With Lower Urinary Tract Symptom and its Relations With Prostatic Urethral Angulation / 대한배뇨장애요실금학회지

Purpose@#To compare improvement of lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia in diabetic versus nondiabetic patients after transurethral resection of the prostate (TURP) or holmium laser enucleation of the prostate (HoLEP). @*Methods@#The medical records of 437 patients who underwent TURP or HoLEP at a tertiary referral center from January 2006 to January 2022 were retrospectively analyzed. Among them, 71 patients had type 2 diabetes. Patients in the diabetic mellitus (DM) and non-DM groups were matched 1:1 according to age, baseline International Prostate Symptom Score (IPSS), and ultrasound measured prostate volume. Changes in LUTS were assessed at 3 months after surgery using IPSS and evaluated by categorizing patients according to prostatic urethral angulation (PUA; <50° vs. ≥50°). Medication-free survival after surgery was also investigated. @*Results@#No significant differences were noted between the DM and non-DM groups in baseline characteristics except for comorbidities (i.e., hypertension, cerebrovascular disease, and ischemic heart disease, P=0.021, P=0.002, and P=0.017, respectively) and postvoid residual urine volume (115±98 mL vs. 76±105 mL, P=0.028). Non-DM patients showed significant symptomatic improvement regardless of PUA, while DM patients demonstrated improvement in obstructive symptoms only in those with large PUA (≥51°). Among patients with small PUA, DM patients had worse medication-free survival after surgery compared to controls (P=0.044) and DM was an independent predictor of medication reuse (hazard ratio, 1.422; 95% confidence interval, 1.285–2.373; P=0.038). @*Conclusions@#DM patients experienced symptomatic improvement after surgery only in those with large PUA. Among patients with small PUA, DM patients were more likely to reuse medication after surgery.

Benefits of Adjuvant Chemotherapy for Clinical T3-4N0 Rectal Cancer After Preoperative Chemoradiotherapy / 전남의대학술지

While the guidelines for adjuvant chemotherapy (AC) for colon cancer are relatively standardized, those for early rectal cancer are still lacking. We therefore evaluated the role of AC in clinical stage II rectal cancer treatment after preoperative chemoradiotherapy (CRT). Patients diagnosed with early rectal cancer (defined by clinical stage T3/4, N0) who completed CRT followed by surgery were enrolled in this retrospective study. To evaluate the role of AC, we analyzed the risk of recurrence and survival based on clinicopathologic parameters and adjuvant chemotherapy. Of the 112 patients, 11 patients (9.8%) experienced recurrence and five patients (4.8%) died. In a multivariate analysis, circumferential resection margin involvement (CRM+) on magnetic resonance imaging at diagnosis, CRM involvement following neoadjuvant therapy (ypCRM+), tumor regression grade (≤G1) and no-AC were considered poor prognostic factors for recurrence free survival (RFS). In addition, ypCRM+ and no-AC were associated with poor overall survival (OS) in the multivariate analysis. AC including 5-FU monotherapy demonstrated the benefits of reduced recurrence and prolonged survival in clinical stage II rectal cancer, even in pathologic stage following neoadjuvant therapy (ypStage) 0-I. Further prospective studies are needed to verify the benefit of each regimen of AC and the development of a method that can accurately predict CRM status before surgery, and a vigorous treatment that can induce CRM non-involvement (CRM−) should be considered even in early stages of rectal cancer.

Geriatric functional assessment for decision-making on adjuvant chemotherapy in older colon cancer patients

Background/Aims@#Despite the increasing need for geriatric assessment prior to chemotherapy, the method for this assessment remains inadequate for older cancer patients. We aimed to propose a simple assessment method to predict the performance of adjuvant chemotherapy in older patients after colon cancer surgery. @*Methods@#This prospective study included patients over 65 years of age who were scheduled for adjuvant chemotherapy after colon cancer surgery. Before initiating chemotherapy, their functional status was assessed on the basis of activities of daily living (ADL)/instrumental activities of daily living (IADL). These parameters were analyzed with clinical characteristics and the patterns of adjuvant chemotherapy. The focus was on the completion rate of adjuvant chemotherapy. @*Results@#A total of 89 patients with a median age of 72 years were analyzed. Among them, 54 (61%) were non-impaired and 35 (39%) were impaired regarding their ADL/IADL classification. Low body mass index and impairment of ADL/IADLs were significantly associated with chemotherapy interruption. Among toxicities, fatigue and hand-foot syndrome were independent prognostic factors for chemotherapy interruption. Impairments of ADL/IADL were significantly associated with fatigue regardless of age. Based on age and ADL/IADL stratification, younger patients (≤ 72 years) and/or those who were ADL/IADL non-impaired were significantly more likely to complete adjuvant chemotherapy than older patients (> 72 years) and ADL/IADL impaired patients (p = 0.038). This was regardless of the chemotherapy regimen. @*Conclusions@#Functional assessment using ADL/IADL is a convenient method to predict chemotherapy toxicity and performance. These results suggested that routine screening for ADL/IADLs could guide appropriate patient selection for the completion of adjuvant chemotherapy and predict expected outcomes.

The association between the neutrophil-to-lymphocyte ratio and bacteremia in elderly patients admitted to the emergency department

Objective@#Bacteremia is a common cause of increased morbidity and mortality in elderly patients, but early diagnosis and identification are complex. The neutrophil-to-lymphocyte count ratio (NLR) is suggested as a useful indicator for diagnosing bloodstream infections. This study evaluated whether the NLR at admission is associated with bloodstream infections in older patients admitted to the emergency department. @*Methods@#A retrospective, multicenter analysis was performed on patients admitted to the emergency department from November 2016 to February 2017. We included patients aged 65 years and older who visited the emergency department with medical problems. Baseline NLR values were measured upon admission to the emergency department. The primary outcome was a positive blood culture. @*Results@#A total of 1,815 patients were included in this study. The median age was 77.25±7.38 years, and bacteremia was identified in 290 older patients (15.9%). The NLR was significantly higher in the bacteremia group (15.95±22.03) than in the non-bacteremia group (8.76±8.74, P<0.001). In the multivariate logistic regression analysis, the NLR was associated with bacteremia after adjusting for confounding factors as continuous variables (odds ratio [OR], 1.033; 95% confidence interval [CI], 1.009-1.057) and categorical variables (NLR ≥10; OR, 2.018; 95% CI, 1.246-3.268). The area under the curve of the NLR was determined to be 0.667 (95% CI, 0.639-0.694). @*Conclusion@#These results indicate that the NLR at admission to the emergency department is associated with bloodstream infections. Early suspicion of bacteremia, by determining the initial NLR value, will help treat bacteremia in elderly patients.

Venetoclax with Azacitidine Induced Tumor Lysis Syndrome in an Elderly Patient with Acute Myeloid Leukemia: A Case Report

Combination treatment with hypomethylating agents (HMAs) and venetoclax is being used increasingly in elderly patients with acute myeloid leukemia (AML).Venetoclax with HMAs has been reported to be associated with tumor lysis syndrome (TLS) in AML patients with high leukemic burden. We present a case of an elderly AML patient with low leukemic burden who developed TLS while receiving venetoclax and azacitidine (AZA). A 74-year-old man with newly diagnosed AML with NPM1 mutation received combination therapy with venetoclax and AZA in an outpatient clinic. Within 12 hours after starting venetoclax and AZA, the patient was admitted to the emergency room with fever, general weakness, and laboratory findings consistent with TLS. Based on our results, we recommend monitoring at the start of the treatment with venetoclax and HMAs to prevent and control TLS regardless of the leukemic burden and favorable genetic ris

Effect of acupuncture on vascular endothelial function in patients of polycystic ovary syndrome with different glucose tolerance status / 中国针灸

OBJECTIVE@#To observe the effect of acupuncture on vascular endothelial function in patients of polycystic ovary syndrome (PCOS) with impaired glucose tolerance (IGT) and normal glucose tolerance (NGT).@*METHODS@#A total of 140 patients with PCOS were divided into an IGT group (70 cases, 11 dropped off) and a NGT group (70 cases, 9 cases dropped off). The patients in the two groups were treated with full-cycle acupuncture at Zhongwan (CV 12), Guanyuan (CV 4), Qihai (CV 6), Tianshu (ST 25), etc. once every other day, 3 times a week, for 3 months. Before and after treatment, TCM symptom score, insulin resistance index [including fasting plasma glucose (FPG), 2-hour blood glucose (2hPG), fasting serum insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR)] and vascular endothelial related factors [including asymmetric dimethylarginine (ADMD), endothelin-1 (ET-1), malondialdehyde (MDA), nitric oxide (NO)] were compared between the two groups; in addition, the obese subgroup and non-obese subgroup of the two groups were further compared.@*RESULTS@#Compared before treatment, the TCM symptom scores, ADMD, ET-1 and MDA after treatment were decreased (@*CONCLUSION@#Acupuncture could improve vascular endothelial function in PCOS patients, IGT patients have better efficacy than NGT patients, and obese patients have better efficacy than non-obese patients.

The effectiveness of the capnographic unit and ultrasonography for confirmation of nasogastric tube location at the emergency room

Objective@#This study was designed to verify the effectiveness of capnography and ultrasound for confirmation of the location of the nasogastric tube (NGT) in the emergency room (ER). @*Methods@#In this prospective single-blinded study, carried out on 137 patients over 19 years of age, the NGT location was confirmed by capnography in 63 patients and by ultrasound in 74 patients. The capnography and ultrasound scans were performed in random order, while auscultation was performed and chest X-rays were taken for all patients. Capnography was performed by checking the end-tidal carbon dioxide (ETCO2) level and the wave form after inserting the NGT. An ultrasound scan was conducted on the neck, gastroesophageal junction and stomach. The X-ray results were interpreted by a doctor who had not inserted the NGT. @*Results@#The sensitivity and specificity of auscultation were 98.43% and 10%, respectively. After 30 cm of NGT was inserted ETCO2 was measured through the capnography, and was found to be ranging from 0-23. When the capnography showed an ETCO2 value of less than 4, the tube was considered to be inserted in the stomach. In such a case, the specificity was 100%, but the sensitivity was only 46.43%. The sensitivity and specificity of the ultrasound were 92.96% and 66.67%, respectively. In addition, the positive predictive value was confirmed to be 100% and 98.51% when using capnography and ultrasound, respectively. @*Conclusion@#When the NGT is inserted in the ER, it is possible to use ultrasound and capnography for confirmation of its location. However, in some patients, when neither method can confirm the location, a chest X-ray will still be needed.

The Use of Gonadotropin-Releasing Hormone Agonist Does Not Affect the Development of Cardiovascular Disease in Prostate Cancer Patients: a Nationwide Population-Based Cohort Study

BACKGROUND@#The objective of this study was to investigate whether androgen deprivation therapy (ADT) with gonadotropin-releasing hormone agonist (GnRHa) in prostate cancer (Pca) patients is associated with cardiovascular disease in the cohort based from the entire Korean population.@*METHODS@#Using the Korean National Health Insurance database, we conducted an observational study of 579,377 men who sought treatment for Pca between January 1, 2012 and December 31, 2016. After excluding patients with previously diagnosed cardiovascular disease or who had undergone chemotherapy, we extracted the data from 2,053 patients who started GnRHa (GnRHa users) and 2,654 men who were newly diagnosed with Pca (GnRHa nonusers) between July 1, 2012, and December 31, 2012, with follow-up through December 31, 2016. The primary outcomes were cerebrovascular attack (CVA) and ischemic heart disease (IHD).@*RESULTS@#GnRHa users were older, were more likely to reside in rural areas, had lower socioeconomic status, and had more comorbidities than nonusers (all P < 0.050). Although GnRHa users had an increased incidence of CVA and IHD (P = 0.013 and 0.048, respectively) in univariate analysis, GnRHa use was not associated with the outcomes in multivariate analysis. Furthermore, the cumulative duration of ADT was not associated with the outcomes whereas the associations between age at diagnosis with all diseases were significant.@*CONCLUSION@#Our complete enumeration of the Korean Pca population shows that ADT is not associated with increased risks of cardiovascular disease.

Cisplatin-induced Atrioventricular Block Requiring a Pacemaker: Two Case Reports and a Literature Review

Chemotherapeutic drugs can cause cardiac toxicities such as cardiomyopathy, arrhythmia, and cardiovascular disease. The well-known side effects of cisplatin are nephrotoxicity, nausea, vomiting, and electrolyte imbalance. Cardiotoxicity induced by cisplatin is rare, and its pathophysiology is unknown. Here, we present two cases of complete and high-degree atrioventricular (AV) block that occurred during cisplatin-based chemotherapy and required pacemaker placement. A 64-year-old woman and a 75-year-old man, who had no underlying heart disease, developed dyspnea without chest pain and bradycardia during cisplatin-based chemotherapy. However, there were no significant differences in their serum electrolyte levels, cardiac enzyme levels, and echocardiography results before and after drug administration. The ECGs were confirmed with complete AV block and highdegree AV block, which requiring pacemaker placement. We assume that cisplatin directly caused the complete, high-degree AV block, which required a pacemaker placement in our cases. In such cases, a cumulative dose of cisplatin over 240 mg/m 2 is a risk factor for early symptoms of AV block. If patients complain of dyspnea without chest pain during cisplatin-based chemotherapy, arrhythmic complications should be considered. This information may be helpful for clinicians treating patients with cisplatin chemotherapy.

Effect of combined treatment with acupuncture, moxibustion and medication on endometrial receptivity and expression of serum HOXA10 in polycystic ovary syndrome of kidney deficiency and blood stagnation / 中国针灸

OBJECTIVE@#To compare the clinical effect of the combined treatment of acupuncture, moxibustion, Chinese herbal medicine and western medication and simple western medication on polycystic ovary syndrome (PCOS) of kidney deficiency and blood stagnation pattern and explore the effect on endometrial receptivity and the expression of serum homeobox gene A10 (HOXA10).@*METHODS@#A total of 60 patients with PCOS of kidney deficiency and blood stagnation pattern were randomized into a combined treatment group and a western medication group, 30 cases in each one. In the western medication group, on the fifth day of menstruation, clomiphene citrate tablets were taken orally, 50 mg each time, once daily, consecutively for 5 days. On the day when the follicle diameter was ≥ 18 mm, chorionic gonadotrophin for muscular injection, a dose of 10 000 U was given. Before sleep, the aspirin enteric-coated tablets were taken orally, 50 mg (except during menstruation). In the combined treatment group, on the base of the treatment as the western medication group, acupuncture and moxibustion were adopted and the Chinese herbal for tonifying the kidney and activating blood circulation was taken orally. The acupoints were Guanyuan (CV 4), Qihai (CV 6), Zusanli (ST 36), Sanyinjiao (SP 6), Zigong (EX-CA 1), etc. Acupuncture was remained for 30 min each time, once every two days and discontinued during menstruation. Chinese herbal was given from the 3rd day of menstruation till the onset of the next menstruation, one dose each day. After consecutive treatment for 3 menstrual cycles in the two groups, the real-time polymerase chain reaction (RT-PCR) method was adopted to determine the expression of serum HOXA10 before and after treatment in the patients of the two groups. The endometrial thickness at ovulatory phase, uterine arterial flow 7 days after ovulation [including uterine arterial pulsatility index (PI), resistance index (RI), peak systolic velocity (PSV)/end diastolic velocity (EDV), meaning S/D], pregnancy rate and the score of Chinese medicine symptoms before and after treatment were compared in the patients between the two groups.@*RESULTS@#① After treatment, the expression of serum HOXA10 was higher than that before treatment in the patients of the two groups (@*CONCLUSION@#The combined treatment with acupuncture, moxibustion and medication effectively improves endometrial receptivity and uterine arterial flow in the patients with PCOS of kidney deficiency and blood stagnation pattern and increases pregnancy rate. The therapeutic effect is better than the simple western medication and its mechanism is probably related to the regulation of serum HOXA10 expression.

Hearing Outcomes and Prognostic Factors in Idiopathic Sudden Sensorineural Hearing Loss Patients with Combined Intratympanic and Systemic Steroid Therapy / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Hearing outcomes and prognostic factors of idiopathic sudden sensorineural hearing loss (SSNHL) were investigated in patients who underwent combined intratympanic and systemic steroid therapy. SUBJECTS AND METHOD: This study was performed by retrospective chart review. Clinical outcomes and prognostic factors were evaluated in 147 patients who received intratympanic steroid plus systemic steroid therapy. RESULTS: Complete hearing recovery was achieved in 36.7% (n=54) of the patients, partial recovery in 12.9% (n=19), slight recovery in 12.3% (n=18), and total recovery in 61.9% (n=91). Age was identified as an independent, negative prognostic factor for hearing recovery. The recovery rates of the down sloping and profound types were poorer than those of the up sloping type as determined by audiography. CONCLUSION: The results of this study suggest that the combined treatment of intratympanic and systemic steroids for idiopathic SSNHL results in high hearing recovery rates, and that the down-sloping and profound types of audiogram patterns and age are negative prognostic factors.

Localized Mass-Forming Autoimmune Pancreatitis Associated with an Intraductal Papillary Mucinous Neoplasm Mimicking Pancreatic Cancer / 대한내과학회지

Autoimmune pancreatitis (AIP) has been increasingly recognized in recent years, and most cases are diagnosed without surgery. However, focal-type mass-forming AIP is difficult to differentiate from pancreatic cancer without surgical resection. A 61-year-old male patient with a clinical impression of pancreatic cancer underwent surgery. A postoperative pathologic examination showed locally dense lymphoplasma cell infiltration and numerous lymphoid follicles with fibrosis and a low-grade intraductal papillary mucinous neoplasm (IPMN). Here, we report the first case of localized mass-forming AIP combined with a low-grade IPMN, which mimicked pancreatic cancer, in Korea.

Factors Influencing the Acceptance of Transrectal Ultrasound-Guided Prostate Biopsies

PURPOSE: This study aimed to improve prostate biopsy compliance by analyzing the factors that influence the acceptance of prostate biopsy by patients to whom transrectal ultrasound (TRUS)-guided prostate biopsy is recommended for suspected prostate cancer. MATERIALS AND METHODS: The subjects of this study were 268 patients to whom TRUS-guided prostate biopsy was recommended from January to June 2011 and who completed a questionnaire. Patients who showed a prostate-specific antigen (PSA) increase to more than 4.0 ng/mL or abnormal findings on a digital rectal examination and TRUS were recommended to undergo prostate biopsy. The questionnaire consisted of 9 questions about the subjects' demographic characteristics and 15 questions that assessed their knowledge of prostate disease. Fisher exact probability test was conducted to assess the influence of the demographic characteristics and levels of knowledge of prostate disease on acceptance of prostate biopsy. RESULTS: The mean age of the subjects was 66.2 years (range, 43-83 years). Of the cohort, 188 patients (70.7%) agreed to the prostate biopsy and 78 patients (29.3%) refused. In terms of demographic characteristics, the patients' acceptance of prostate biopsy was associated only with education level. Patients with relatively lower education levels had a higher acceptance rate for prostate biopsy (80.0% vs. 65.9%, p=0.018). Other demographic factors, as well as the degree of knowledge of prostate disease, had no significant effect on the acceptance rate. CONCLUSIONS: The patients' acceptance of prostate biopsy can be influenced by demographic characteristics, especially education level. Therefore, when prostate biopsy is recommended to patients, their demographic characteristics should be taken into consideration.
