RESUMO
Background@#The quality-of-life of patients with irritable bowel syndrome is low; incorrect diagnosis/treatment causes economic burden and inappropriate consumption of medical resources. This survey-based study aimed to analyze the current status of irritable bowel syndrome treatment to examine differences in doctors’ perceptions of the disease, and treatment patterns. @*Methods@#From October 2019 to February 2020, the irritable bowel syndrome and Intestinal Function Research Study Group of the Korean Society of Neurogastroenterology and Motility conducted a survey on doctors working in primary, secondary, and tertiary healthcare institutions. The questionnaire included 37 items and was completed anonymously using the NAVER platform (a web-based platform), e-mails, and written forms. @*Results@#A total of 272 doctors responded; respondents reported using the Rome IV diagnostic criteria (amended in 2016) for diagnosing and treating irritable bowel syndrome.Several differences were noted between the primary, secondary, and tertiary physicians’ groups. The rate of colonoscopy was high in tertiary healthcare institutions. During a colonoscopy, the necessity of random biopsy was higher among physicians who worked at tertiary institutions. ‘The patient did not adhere to the diet’ as a reason for ineffectiveness using low-fermentable oligo-, di-, and mono-saccharides, and polyols diet treatment was higher among physicians in primary/secondary institutions, and ‘There are individual differences in terms of effectiveness’ was higher among physicians in tertiary institutions. In irritable bowel syndrome constipation predominant subtype, the use of serotonin type 3 receptor antagonist (ramosetron) and probiotics was higher in primary/secondary institutions, while serotonin type 4 receptor agonist was used more in tertiary institutions. In irritable bowel syndrome diarrhea predominant subtype, the use of antispasmodics was higher in primary/secondary institutions, while the use of serotonin type 3 receptor antagonist (ramosetron) was higher in tertiary institutions. @*Conclusion@#Notable differences were observed between physicians in primary/secondary and tertiary institiutions regarding the rate of colonoscopy, necessity of random biopsy, the reason for the ineffectiveness of low-fermentable oligo-, di-, and mono-saccharides, and polyols diet, and use of drug therapy in irritable bowel syndrome. In South Korea, irritable bowel syndrome is diagnosed and treated according to the Rome IV diagnostic criteria, revised in 2016.
RESUMO
To conduct textual research on the records of Chrysanthemi Flos in the ancient literature from the aspects of name, origin, species, scientific name, origin, harvesting, processing, quality and so on, and the modern literature was sorted out to clarify the relationship between the ancient and modern times, so as to provide a reference for the development of famous classical formulas containing Chrysanthemi Flos. Chrysanthemi Flos is an ornamental, edible and medicinal plant in China, it has many aliases, but it has been recorded in this materia medica under the name of Juhua, Ganju and Ganjuhua. Before the Tang dynasty, medicinal Chrysanthemi Flos mainly collected wild products, including yellow flowers and white flowers, of which the mainstream of yellow flowers was originally Dendranthema lavandulifolium and D. potentilloides, the mainstream of white flowers is D. vestitum and D. chanetii. The cultivation of medicinal Chrysanthemi Flos began in the Northern Song dynasty, and wild D. lavandulifolium, D. potentilloides, D. vestitum and D. chanetii were selected through long-term interspecies and intraspecies crossbreeding, which gradually formed the current cultivar D. morifolium. After chrysanthemums were introduced abroad, foreign scholars began to name chrysanthemums with Linnaeus's plant classification system. In 1792, Mathier named chrysanthemums as Chrysanthemum morifolium and continued to this day, and all the editions of Chinese Pharmacopoeia adopted this scientific name. In the Song dynasty, many local varieties such as Nanyangju, Dengzhouhuang and Dengzhoubai appeared. By the time of the Republic of China, five famous authentic varieties, namely Huaiju, Boju, Chuju, Gongju and Hangju, had been cultivated for medicinal purposes. Boju has been the best medicinal variety since the late Qing dynasty. Hangbaiju has been famous for its tea use, especially the best quality of Huju. Chuju has its own unique characteristics, and it is of good quality both for medicine and tea. Gongju has always been a good tea chrysanthemum. Chrysanthemums are traditionally harvested in September of the lunar calendar, but some of the new varieties cultivated nowadays are harvested earlier. The embryo chrysanthemum in Hangbaiju is a commodity type that collects unopened buds in advance. In ancient times, chrysanthemums were mainly dried in the shade, in modern times, drying methods include drying in the shade, drying in the oven and drying in the sun after steaming. At present, hot air drying is mostly used. In terms of processing, Chrysanthemi Flos was used raw products in ancient times, in modern times, it is still widely used, sometimes stir fried(including stir-fried charcoal). Due to different varieties, producing areas and processing methods, there are certain differences in the proportion of ingredients contained in chrysanthemum. Therefore, it is suggested that chrysanthemums with different varieties, origins and processing methods should be selected according to clinical indications in the development of famous classical formula preparations containing Chrysanthemi Flos.
RESUMO
By reviewing the ancient and modern literature, the name, origin, medicinal parts and other aspects of Linderae Radix in famous classical formulas were systematically sorted out, so as to provide a basis for development of famous classical formulas containing this herb. Linderae Radix was first recorded in Bencao Shiyi in the Tang dynasty under name of Pangqi, and since Rihuazi Bencao of the Five dynasties, all generations of materia medica have used Wuyao as its proper name of the herb. The mainstream source of Linderae Radix used in the past dynasties is dried tuberous roots of Lindera aggregata contained in the 2020 edition of Chinese Pharmacopoeia. The origins of Linderae Radix recorded in the past dynasties are mainly Guangdong, Guangxi, Hunan, Zhejiang, Anhui and others, since the Song dynasty, Tiantai county in Zhejiang province has been regarded as the authentic producing place, in modern times, it is still the authentic place of origin. At harvesting, in ancient times, the harvesting time of the roots was mostly in August, while in modern times, Linderae Radix is mostly harvested in winter and spring or throughout the year, and is dried directly after harvesting or cut thin slices and dried in the place of production. At processing, Linderae Radix was processed by removing the peel and heart, wine roasting, vinegar roasting and other methods in ancient times, and in modern times, it is mostly used in raw form as medicine. In conclusion, it is suggested that the processing method of fresh slicing and drying in the place of origin in the 2020 edition of Chinese Pharmacopoeia should be adopted if Linderae Radix is involved in the development of famous classical formulas.

RESUMO
To explore the feasibility of applying magnetic stimulation technology to the movement control of animal robots, the influence of coil radius, number of turns and other factors on the intensity, depth and focus of magnetic stimulation was simulated and analyzed for robot pigeons. The coil design scheme was proposed. The coil was placed on the head and one of the legs of the pigeon, and the leg electromyography (EMG) was recorded when magnetic stimulation was performed. Results showed that the EMG was significantly strengthened during magnetic stimulation. With the reduction of the output frequency of the magnetic stimulation system, the output current was increased and the EMG was enhanced accordingly. Compared with the brain magnetic stimulation, sciatic nerve stimulation produced a more significant EMG enhancement response. This indicated that the magnetic stimulation system could effectively modulate the functions of brain and peripheral nerves by driving the coil. This study provides theoretical and experimental guidance for the subsequent optimization and improvement of practical coils, and lays a preliminary theoretical and experimental foundation for the implementation of magnetic stimulation motion control of animal robots.

This article systematically sorted out and researched the name, origin, harvesting and other aspects of Rhapontici Radix by referring to ancient materia medica, medical books and prescription books, combined with modern literature, in order to provide a reference basis for the development of the famous classical formulas containing this herb. According to the results of the herbal textual research, it can be seen that all the generations of the materia medica have taken Loulu as the proper name, and there are also aliases such as Luligen, Laowenghua and Jiahao. The mainstream base of Rhapontici Radix recorded in the past dynasties was the present Compositae plant Rhaponticum uniflorum, which is mostly used as medicine with roots. Since the Tang dynasty, the stems and leaves of Siphonostegia chinensis have been used as Rhapontici Radix in the northern region. Until modern times, Qizhou Pharmacognosy began to differentiate it into two categories, Qizhou Loulu and Yuzhou Loulu, according to the commodity circulation at that time, producing area and origin, of which Yuzhou Loulu is the roots of Echinops latifolius, a plant of Compositae family. In ancient times, the quality of Loulu was based on "the one that comes out of Shanzhou is the best". However, in modern times, the quality of Qizhou Loulu is better if the surface is black, neat, sturdy, firm, not broken, and without a withered heart, while the quality of Yuzhou Loulu is better if the branches are thick and long with an earthy-brown surface, solid texture and neat in length. In ancient times, most of the harvesting and processing of Loulu was "harvesting the roots in lunar August and drying them in the shade", while in modern times, the roots are mostly excavated in the spring and autumn, and dried in the sun. Its ancient method of processing is to mix and steam with licorice, nowadays, it is prepared by removing impurities, washing, moistening thoroughly, cutting into thick slices and drying in the sun, and then taking the raw products as medicine. Based on the research conclusion, it is suggested that when developing and utilizing the famous classical formulas containing Loulu, the background of the formula should be verified, and if the original formula indicated the requirement of processing, it should be processed according to the requirement, but if not, it is recommended to use raw products as medicine.
RESUMO
Accumulating evidence has confirmed the links between transfer RNA (tRNA) modifications and tumor progression. The present study is the first to explore the role of tRNA methyltransferase 5 (TRMT5), which catalyzes the m1G37 modification of mitochondrial tRNAs in hepatocellular carcinoma (HCC) progression. Here, based on bioinformatics and clinical analyses, we identified that TRMT5 expression was upregulated in HCC, which correlated with poor prognosis. Silencing TRMT5 attenuated HCC proliferation and metastasis both in vivo and in vitro, which may be partially explained by declined extracellular acidification rate (ECAR) and oxygen consumption rate (OCR). Mechanistically, we discovered that knockdown of TRMT5 inactivated the hypoxia-inducible factor-1 (HIF-1) signaling pathway by preventing HIF-1α stability through the enhancement of cellular oxygen content. Moreover, our data indicated that inhibition of TRMT5 sensitized HCC to doxorubicin by adjusting HIF-1α. In conclusion, our study revealed that targeting TRMT5 could inhibit HCC progression and increase the susceptibility of tumor cells to chemotherapy drugs. Thus, TRMT5 might be a carcinogenesis candidate gene that could serve as a potential target for HCC therapy.

Wuzhi tablet (WZ) is a prescribed herbal medicine extracted from Schisandra sphenanthera, which is widely used to protect the liver injury and drug-induced hepatotoxicity in clinical practices. Previous studies showed that WZ significantly increased the blood concentrations of tacrolimus, cyclosporine A, paclitaxel by inhibiting the cytochrome P450 3A (CYP3A)-mediated metabolism. CYP3A4 and CYP3A5 are the most important isoenzymes among the CYP3A subfamily. However, there are some differences in the catalytic and inhibitory activities between CYP3A4 and CYP3A5, which may lead to different risk of drug-drug and herb-drug interactions, and the risks may be further amplified in vivo. Currently, few reports have compared the herbal medicine inhibitory effects between CYP3A4 and CYP3A5 mediated metabolic reactions. Therefore, detailing the inhibitory effect of WZ on CYP3A4 and CYP3A5 will help understand and predict the potential herb-drug interaction. The results showed that WZ inhibited CYP3A4 and CYP3A5 in a NADPH-, time- and concentration- dependent manner. WZ showed more potent inhibition on CYP3A5 than CYP3A4. Cautions warranted when combining WZ with other therapeutic drugs to avoid the potential herb-drug interaction.
RESUMO
By consulting ancient herbal medicines and medical books, combined with modern documents and field investigations, the textual research of Pheretima has been conducted to verify the name, origin, producing area, quality, harvesting and processing changes, and sort out the relationship of origin between ancient and modern times, so as to provide reference and basis for the development and utilization of the related famous classical formulas. Through textual research, it is known that there are many aliases for Pheretima, the rectification of name was "Qiuyin" or "Baijing Qiuyin" in materia medica books. In the Song dynasty and later prescription books, the prescription name is mostly Dilong. From the beginning of Yaowu Chuchanbian (《药物出产辨》), Dilong was used as the rectification of name. It is widely distributed in our country, which is produced all over the country and mostly wild. According to ancient Pheretima with "Baijing Dilong", "Jingbai Shenzi" and "Datiao" as the principles of medicine, combined with historical origin, producing area and easy access, it is confirmed that Pheretima used in ancient times to the present is mainly Pheretima aspergillum, and it also has many other Qiuyin as Pheretima for medicinal purposes. Chinese Pharmacopoeia has unified the origin of the Pheretima since the 1995 edition based on historical origins and actual harvesting conditions. The medicinal material processed by P. aspergillum was called Guangdilong, and the medicinal materials processed by P. vulgaris, P. guillelmi and P. pectinifera were called Hudilong. Since then, all the herbal books published in the future are in line with Chinese Pharmacopoeia that was implemented at that time. The authentic production areas of Guangdilong are Guangdong and Guangxi, and the authentic production areas of Hudilong is Jiangsu, Shanghai, Zhejiang and Anhui. The Guangdilong produced in Guangdong and Guangxi has the best quality. After harvesting, remove the soil and offal, wash and dry. Clinically cut into sections for medicine, or prepare medicine according to prescription. The Pheretima in ancient used "Baijing Dilong", "Jingbai Shenzi" and "Datiao" as the mainstream quality evaluation standards. According to historical origins, P. aspergillum should be the main source of Pheretima, and its quality is better than other species. Therefore, it is recommended that Pheretima in Shentong Zhuyutang use P. aspergillum, which is produced in Guangdong, Guangxi and other places. After harvest, the abdomen was opened in time to remove the viscera and sediment, washed and dried.
RESUMO
By consulting ancient Chinese herbal medicines and medical books, combined with modern documents, the textual research of Polygonati Rhizoma has been conducted to verify the name, origin, bitter-flavored Polygonatum species, Latin name evolution, origin, quality evaluation, harvesting and processing changes, so as to provide reference and basis for the development and utilization of the famous classical formulas. Through textual research, it can be seen that there are many other names for Polygonati Rhizoma, and Huangjing is the correct name since Mingyi Bielu. Based on the original research, it is concluded that P. sibiricum and P. cyrtonema were the mainstream of Polygonati Rhizoma before the Tang dynasty, and P. kingianum was added in the Qing dynasty. According to the shape of medicinal materials, these Polygonatum species were called Jitou Huangjing, Jiangxing Huangjing and Dahuangjing. The harvest time of Polygonati Rhizoma is spring and autumn. After harvest, it is steamed and dried in the sun, and its processing method is mainly "nine steaming and nine storms". Bitter-flavored Polygonatum is mainly P. cirrhifolium, P. zanlanscianense, P. curvistylum and P. verticillatum, which are not suitable for medicine. Based on textual research, it is recommended that when developing famous classical formulas and health products with Polygonati Rhizoma as the main raw material, the origin and producing area should be clear and fixed, and P. sibiricum or P. cyrtonema with clear origin should be used. It is necessary to conduct germplasm survey and sampling in the producing area, establish a planting base and a traceability system for Polygonati Rhizoma, in order to control the quality and stabilize the efficacy of the products. The processing method of Polygonati Rhizoma can be determined according to the product function positioning.
RESUMO
Probe electrospray ionization (PESI) is one of the typical types of ambient ionization technology, but its application in quantitative analysis is limited due to its poor sampling stability. Previously, we developed a new micro-pen electrospray ionization tandem mass spectrometry (μPen-ESI-MS/MS) method based on PESI. In this study, a μPen-ESI-MS/MS method to measure testosterone and dextromethorphan in liver microsome samples was developed and validated to further applicate in evaluating drug metabolism stability and CYP450 enzyme activity. A μPen-ESI-MS/MS method for detecting the CYP3A4 substrate testosterone and CYP2D6 substrate dextromethorphan in the liver microsome incubation system were developed, and the linearity, precision and accuracy of the method was validated. The validated method was further used to detect the metabolic stability of testosterone in the liver microsome incubation system. The results showed that the μPen-ESI-MS/MS had high efficiency with 0.3 min spraying time of each sample. The standard curve of the testosterone and dextromethorphan has good linearity (R2 > 0.99), the intra- and inter-batch accuracy of testosterone and dextromethorphan was 95.9%-109.3% and 90.5%-107.3%, respectively; the intra- and inter-batch precision was acceptable with RSD values of 2.4%-13.5% and 3.4%-12.1%. The half-lives of testosterone and dextromethorphan in the liver microsome incubation system were 12 min and 14 min, respectively. This study provided a rapid and sensitive μPen-ESI-MS/MS method for the assay of testosterone and dextromethorphan in liver microsome samples, and provided a new strategy for the evaluation of drug metabolism stability and CYP3A4/CYP2D6 activity.
RESUMO
Acetaminophen (APAP, also known as paracetamol)-induced liver injury is the leading cause of drug-induced liver injury in the world. Wuzhi Tablet (WZ, an ethanol extract of Schisandra sphenanthera) is widely used in clinical practice to protect liver function. Our previous studies have shown that pretreatment with WZ for 3 days can significantly protect against APAP-induced liver injury; however, the effect of different intervals between APAP and WZ treatment on APAP-induced liver injury remains unclear. In this study, the change in liver injury indexes, APAP metabolites, and the activity of cytochrome P450 (CYP450) enzymes after treatment with WZ and APAP at different intervals were determined. The animal experiment was reviewed and approved by the Animal Ethics Committee of Sun Yat-sen University. The results show that 0 h, 0.5 h, and 2 h pretreatment with WZ significantly protected against APAP-induced liver injury in mice, as evidenced by a significant decrease in biochemical parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and malonaldehyde (MDA). WZ inhibited the metabolic activation of APAP mediated by CYP450 enzymes and reduced the formation of APAP metabolites. This study further demonstrates that pretreatment with WZ at different intervals (0 h, 0.5 h, and 2 h before APAP dosing) exerts a significant hepatoprotective effect against APAP-induced liver injury, and a single-dose of WZ inhibits the activity of CYP450 enzymes related to APAP metabolic activation, thereby protecting against APAP-induced hepatotoxicity.
RESUMO
Pregnane X receptor (PXR), a member of nuclear receptor superfamily, plays an important role in xenobiotic and endogenous metabolism, endocrine balance, and cell proliferation, etc. Previous study has shown that pregnenolone 16α-carbonitrile (PCN), a mouse PXR agonist, could induce liver enlargement. And we found that the change in hepatocytes exhibits regional distribution characteristics: hepatocyte enlargement occurs around the central vein (CV) area, while hepatocyte proliferation occurs around the portal vein (PV) area. In this study, the dynamic changes of hepatocytes during PXR-induced liver enlargement were determined. Serum and liver samples from male C57BL/6 mice were collected for biochemical and pathological analysis after PCN treatment for 1, 2, 3, 5 days, respectively. The animal experiment was approved by the Animal Ethics Committee of Sun Yat-Sen University. The results showed that with the increase in the PCN treatment days, the feature of this regional change of hepatocyte around the CV and PV areas became more and more obvious. At the same time, the factors related to hepatocyte enlargement, such as the expression of PXR downstream genes and the hepatic content of triglyceride (TG), has gradually increased. The upregulation of proliferation-related proteins and downregulation of cyclin-dependent kinases inhibitor proteins were observed in the early stage of PCN treatment, suggesting that hepatocyte proliferation occurs earlier than hepatocyte enlargement during PXR-induced liver enlargement. This study reveals the dynamic change of hepatocytes during PXR-induced liver enlargement and provides a new insight in liver enlargement promoted via PXR activation.
RESUMO
OBJECTIVE@#Coronavirus disease 2019 (COVID-19) has become an increasingly severe public health emergency. Although traditional Chinese medicine (TCM) has helped to combat COVID-19, public perception of TCM remains controversial. We used the theory of planned behavior (TPB) to identify factors that affect the intention to use TCM.@*METHODS@#A cross-sectional web-based survey of 10,824 individuals from the general public was conducted between March 16 and April 2, 2020. The participants were recruited using a snowball sampling method. Data were collected using a self-administered questionnaire, based on the TPB. The questionnaire consisted of demographic characteristics and TPB structures. Structural equation modeling was used to identify predictors of intention.@*RESULTS@#The results indicated the model explained 77.5% and 71.9% of intention and attitude variance. Intention to use TCM had the strongest relationship with attitude (P < 0.001), followed by past behavior (P < 0.001), subjective norms (P < 0.001) and perceived behavioral control (P < 0.001). Attitudes toward TCM were significantly affected by perceived behavioral control (P < 0.001), subjective norms (P < 0.001) and cognition of TCM (P < 0.001).@*CONCLUSION@#Attitude is a key factor in determining the intention to use TCM, followed by past behaviors, subjective norms and perceived behavioral control. Our results offer important implications for health policy makers to promote the use of TCM.

Objective:Before the radiotherapy was performed, patients with pelvic tumors were analyzed for the consistency of bladder filling in the three steps of " Immobilization" , " CT Simulation" and " X-ray Simulation" .Methods:In 2014, 105 patients (68 cases of cervical cancer, 32 cases of rectal cancer, 3 cases of vaginal cancer and 2 cases of prostate cancer) with pelvic tumor radiotherapy were randomly assigned to monitor bladder urine volume to a target urine volume of 400 ml. First, patient were exhorted to empty the bladder, and the bladder volume meter BVI 9400 was used to measure the urine volume of the patient after emptying of the bladder. The patient immediately drank about 540 ml of water and suppressed urine, measurements were taken every 0.5 h. At the same time, when the patient complained of " urgency of urine" , bladder urine volume would be measured again and the time would also be recorded. Every other half an hour (emptying, 0.5 h after emptying, 1.0 h after emptying), when complaining of " urgency of urine" , when actually performing urine volume and time were described as: U 0 and t 0, U 0.5 and t 0.5, U 1.0 and t 1.0, U t and t, U T and T. Results:There was a statistically significant difference in gender and age, and women had stronger ability to urinate than men U 1.0( P=0.003), young people had stronger ability to urinate than middle-aged U 1.0( P=0.002). In the three-step comparison, there was no statistically difference between 1 hour after emptying urine volume U 1.0( P=0.177) and the actually performing urine volume U T ( P=0.052). And the final urine volume was concentrated at 298-526 ml. After the patient emptied the urine volume and complained of " urgency of urine" , the time slot was t=(75.2±49.9) min, with the urine volume of U t=(331.2±140.3) ml. And there was no statistically difference between U t and U T ( P=0.198) at X-ray Simulation. Conclusions:The patient emptied the bladder and immediately drank 540 ml of water. After 1 hour of suppressing urine, he complained of " urgency of urine" and achieved the target urine volume (400 ml). At this time, the bladder urine volume U 1.0 was consistency in the immobilization, CT Simulation, and X-ray Simulation.
RESUMO
The present study aimed to regulate the market circulation of Caryophylli Flos and formulate standards for commodity specifications and grades of Caryophylli Flos. Market survey was carried out in four major medicinal material markets with 48 samples of Caryophylli Flos collected. The property, 100-seed weight, impurity percentage, moisture, and eugenol content in Caryophylli Flos of different specifications from different producing areas were determined and analyzed. The results showed that 27.1% of the samples surveyed on the markets did not meet the requirements of Chinese Pharmacopoeia(2020 edition). The 100-seed weight and the property are important factors for the classification of Caryophylli Flos specifications. There were significant differences in the property, 100-seed weight, impurity percentage, and eugenol content in Caryophylli Flos samples of different specifications from different producing areas, and also differences in the proportions of different specifications in Caryophylli Flos samples from different producing areas. The African-originated Xiaohong(medium grade) and Guangxi-originated Xiaohong(medium grade) accounted for 70% and 66.7% respectively, the Indonesian-originated Dahong(top grade) for 56.2%. In conclusion, there are many problems in the circulation of Caryophylli Flos at present, mainly including the loss of origin information, no standards for specifications, non-implementation of grade standards, excessive impurities, and no evidence for authenticity identification. According to the classification of Caryophylli Flos specifications in this study, the average eugenol content of Xiaohong is significantly higher than the Dahong by 4.74%.

Objective To study the functional antibody and protection effect against pneumonia disease after inoculation with PPV23 in HIV-infected adults. Methods In 2015, 63 HIV-infected adults were randomly selected in Hongkou District of Shanghai, and blood samples were collected before and one month after the inoculation of PPV23.Functional antibodies against 4 serotypes (19F, 19A, 23F, 6B) of Streptococcus pneumoniae were detected by opsonophagocyitosis killing assay (OPA).The incidence of pneumonia after PPV23 inoculation was also determined. Results The GMT of OPA antibodies against 4 serotypes 1 month after inoculation with PPV23 was significantly higher than that before inoculation in HIV-infected subjects.After inoculation, the triple growth rates of OPA antibodies against 4 serotypes in HIV-infected subjects were 50%-91.67%.The protection rate against pneumonia was 100% in 2 years after PPV23 inoculation in HIV-infected subjects when compared with same group before inoculation as well as the control group.The HIV-infected patients who received highly active antiretroviral therapy (HAART) or had CD4 count of≥300/μL showed better response in production of OPA antibodies and obtained protection against community-acquired pneumonia (CAP) after receiving PPV23. Conclusion Routine vaccination of PPV23 is recommended for HIV-infected patients with good basic conditions.
RESUMO
Background@#Data on the effects of excess aldosterone on glucose metabolism are inconsistent. This study compared the changes in glucose metabolism in patients with primary aldosteronism (PA) after adrenalectomy or treatment with a mineralocorticoid receptor antagonist (MRA). @*Methods@#Overall, 241 patients were enrolled; 153 underwent adrenalectomy and 88 received an MRA. Fasting glucose, homeostatic model assessment of insulin resistance (HOMA-IR), and homeostatic model assessment of β-cell function (HOMA-β) were compared between the treatment groups after 1 year. Plasma aldosterone concentration (PAC) and factors determining HOMA-IR and PAC were evaluated. @*Results@#No baseline differences were observed between the groups. Fasting insulin, HOMA-IR, and HOMA-β increased in both groups and there were no significant differences in fasting glucose following treatment. Multiple regression analysis showed associations between PAC and HOMA-IR (β=0.172, P=0.017) after treatment. Treatment with spironolactone was the only risk factor associated with PAC >30 ng/dL (odds ratio, 5.2; 95% confidence interval [CI], 2.7 to 10; P<0.001) and conferred a 2.48-fold risk of insulin resistance after 1 year compared with surgery (95% CI, 1.3 to 4.8; P=0.007). @*Conclusion@#Spironolactone treatment might increase insulin resistance in patients with PA. This strengthened the current recommendation that adrenalectomy is the preferred strategy for patient with positive lateralization test. Achieving a post-treatment PAC of <30 ng/dL for improved insulin sensitivity may be appropriate.
