Huanglian Jiedu Wan intervened with "Shi-Re Shanghuo" syndrome through regulating immune balance mediated by biomarker succinate.

With increasing stress in daily life and work, subhealth conditions induced by "Shi-Re Shanghuo" syndrome was gradually universal. "Huanglian Jiedu Wan" (HLJDW) was the first new syndrome Chinese medicine approved for the treatment of "Shi-Re Shanghuo" with promising clinical efficacy. Preliminary small-sample clinical studies have identified some notable biomarkers (succinate, 4-hydroxynonenal, etc.). However, the correlation and underlying mechanism between these biomarkers of HLJDW intervention on "Shi-Re Shanghuo" syndrome remained ambiguous. Therefore, this study was designed as a randomized, double-blind, multicenter, placebo-controlled Phase II clinical trial, employing integrated analysis techniques such as non-targeted and targeted metabolomics, salivary microbiota, proteomics, parallel peaction monitoring, molecular docking and surface plasmon resonance (SPR). The results of the correlation analysis indicated that HLJDW could mediate the balance between inflammation and immunity through succinate produced via host and microbial source to intervene "Shi-Re Shanghuo" syndrome. Further through the HIF1α/MMP9 pathway, succinate regulated downstream arachidonic acid metabolism, particularly the lipid peroxidation product 4-hydroxynonenal. Finally, an animal model of recurrent oral ulcers induced by "Shi-Re Shang Huo" was established and HLJDW was used for intervention, key essential indicators (succinate, glutamine, 4-hydroxynonenal, arachidonic acid metabolism) essential in the potential pathway HIF1α/MMP9 discovered in clinical practice were validated. The results were found to be consistent with our clinical findings. Taken together, succinate was observed as an important signal that triggered immune responses, which might serve as a key regulatory metabolic switch or marker of "Shi-Re Shanghuo" syndrome treated with HLJDW.

[Clinical application value of Huanglian Jiedu Pills in improving syndrome of excess heat and fire toxin based on phase â ¡ clinical trial study on plasma ATP, 4-HNE, and ACTH levels].

A randomized, double-blind, placebo-controlled, multi-center phase Ⅱ clinical trial design was used in this study to recruit subjects who were in line with the syndrome of excess heat and fire toxin, and were diagnosed as recurrent oral ulcers, gingivitis, and acute pharyngitis. A total of 240 cases were included and randomly divided into a placebo group and a Huanglian Jiedu Pills group. The clinical efficacy of Huanglian Jiedu Pills in treating the syndrome of excess heat and fire toxin was evaluated by using the traditional Chinese medicine(TCM) syndrome scale. Enzyme-linked immunosorbent assay(ELISA) was used to determine and evaluate the levels of adenosine triphosphate(ATP), 4-hydroxynonenal(4-HNE), and adrenocorticotropic hormone(ACTH) in plasma of the two groups before and after administration and to predict their application value as clinical biomarkers. The results showed that the disappearance rate of main symptoms in the Huanglian Jiedu Pills group was 69.17%, and that in the placebo group was 50.83%. The comparison between the Huanglian Jiedu Pills group and the placebo group showed that 4-HNE before and after administration was statistically significant(P<0.05). The content of 4-HNE in the Huanglian Jiedu Pills group decreased significantly after administration(P<0.05), but that in the placebo group had no statistical significance and showed an upward trend. After administration, the content of ATP in both Huanglian Jiedu Pills group and placebo group decreased significantly(P<0.05), indicating that the energy metabolism disorder was significantly improved after administration of Huanglian Jiedu Pills and the body's self-healing ability also alleviated the increase in ATP level caused by the syndrome of excess heat and fire toxin to a certain extent. ACTH in both Huanglian Jiedu Pills group and placebo group decreased significantly after administration(P<0.05). It is concluded that Huanglian Jiedu Pills has a significant clinical effect, and can significantly improve the abnormal levels of ATP and 4-HNE in plasma caused by the syndrome of excess heat and fire toxin, which are speculated to be the effective clinical biomarkers for Huanglian Jiedu Pills to treat the syndrome of excess heat and fire toxin.

The relationship between umbilical cord blood vitamin A levels and late preterm infant morbidities: a prospective cohort study.

The aim of this study is to explore the association between umbilical cord blood (UCB) vitamin A levels and late preterm infants morbidities. We conducted a prospective cohort study of 208 late-preterm infants(from 34 0/7 to 36 6/7 weeks gestational age) between January 1, 2014 and June 30, 2015. UCB specimens were collected shortly after birth, and vitamin A levels were determined by enzyme-linked immunosorbent assay. Prevalence of low UCB vitamin A level < 0.7 µmol/L was 37.5% in late preterm infants. In comparison to vaginal delivery, cesarean section was associated with UCB vitamin A level < 0.7 µmol/L (P < 0.001). Nevertheless, UCB vitamin A levels did not correlate with gestational age, birth weight, and gender. UCB vitamin A level < 0.7 µmol/L was not an independent risk factor for hospitalization, oxygen supplementation, hyperbilirubinemia, sepsis, and respiratory distress syndrome.Conclusions: Low umbilical cord blood vitamin A levels are common among late-preterm infants. Cesarean section delivery is associated with low umbilical cord blood vitamin A level. Low umbilical cord blood vitamin A levels at birth do not increase morbidity of late-preterm infants, including hyperbilirubinemia, sepsis, and respiratory distress syndrome. What is Known: • Late preterm infants have a higher morbidity and mortality rates when compared to term infants. • Low plasma vitamin A levels increase the risk of preterm infants' morbidity. What is New: • Late preterm infants commonly have low level of umbilical cord blood vitamin A. • Low umbilical cord blood vitamin A level at birth appears to be not associated with the morbidity of late-preterm infants. • Cesarean section is associated with low umbilical cord blood vitamin A level < 0.7 µmol/L compared with vaginal delivery.

Clinical characteristics and antimicrobial patterns in complicated intra-abdominal infections: a 6-year epidemiological study in southern China.

Complicated intra-abdominal infection (cIAIs) are a common and important cause of morbidity worldwide. In this study, the clinical features, microbiological profiles, antimicrobial patterns and treatments of 3233 cIAI patients (mean age, 47.6 years; 54.7% male) with 3531 hospitalisations from 2008-2013 were retrospectively investigated. The most commonly isolated bacteria were Escherichia coli (47.6%), Klebsiella pneumoniae (16.9%), Enterococcus faecalis (10.4%) and Pseudomonas aeruginosa (8.8%). Ciprofloxacin, aminoglycoside (gentamicin), piperacillin/tazobactam and carbapenems exhibited activity against 53%, 76%, 88% and 100% of extended-spectrum ß-lactamase (ESBL)-positive Enterobacteriaceae isolates, respectively. Pseudomonas aeruginosa isolates exhibited 100%, 95%, 88%, 71% and 76% susceptibility to aminoglycoside (gentamicin), ciprofloxacin, meropenem, imipenem and ceftazidime, respectively, and Enterococcus remained 100% susceptible to vancomycin and linezolid. ß-Lactam antibacterials other than penicillin (specifically third-generation cephalosporins) and imidazole derivatives (ornidazole and metronidazole) were the most common first-line treatments. Patients subjected to regimen change after initial antibiotic treatment had predisposing conditions (e.g. older age, more severe co-morbidities) and a higher incidence of P. aeruginosa infection; in addition, these patients encountered a higher average cost of care and worse clinical outcomes compared with those without medication modification. Taken together, these findings indicate the importance of appropriate initial empirical therapy and suggest the use of combination therapy comprising cephalosporins and metronidazole.

[Clinical characteristics of 7 patients with gestational diabetes insipidus].

OBJECTIVE: To investigate the clinical feature, treatment and prognosis of both the mother and the fetus with gestational diabetes insipidus. METHODS: A total of 7 cases of gestational diabetes insipidus collected in the First Affiliated Hospital of Wenzhou Medical College, Wenzhou Combination of Traditional Chinese Medicine with Western Medicine Hospital, and Zhejiang Taizhou Hospital from June 1993 to June 2006 were analyzed retrospectively. RESULTS: Seven cases symptoms all characterized by excessive thirst polydipsia and polyuria. The average 24 h urinary output was between 11 L to 13 L and manifested of hypobaricuria. After effective treatment (three cases were treated with 1-deamino-8-D-arginine vasopressin, another three patients were managed with hydrochlorothiazide, and the last one was cured with antisterone), seven patients with gestational diabetes insipidus did not have any severe consequences. Their symptoms of excessive thirst, polyuria, and polydypsia disappeared from 7 days to 3 months after parturition. Urinary volume returned to normal standard of 1000-2000 ml during 24 hours. Specific gravity of urine recovered normally between a range 1.015-1.025 and serum sodium recovered between 135-147 mmol/L. The average duration of illness was 52 days. Eight newborn infants survived. Two of them were sent to neonatal intensive care unit for treatment. One was because of premature delivery caused by antepartum eclampsia, and the other case was one of the twins who had hydronephrosis. The baby of the first case left hospital after 3 weeks' treatment. The latter one's symptom disappeared 2 weeks after delivery. No obvious symptom was discovered among all the babies through follow-up telephone calls 42 days after childbirth. CONCLUSION: Gestational diabetes insipidus is a rare endocrinopathy complicating pregnancy. This disorder is characterized by excessive thirst, polydypsia, polyuria, hypobaric urine and electrolyte disturbances usually manifesting in the third trimester of pregnancy or puerperium. This is a transient syndrome. The first treatment of choice in patients with gestational diabetes insipidus is 1-deamino-8-D-arginine vasopressin and the second-choice is hydrochlorothiazide. Early diagnosis and appropriate management of the disease may reduce the hazard for both the mother and the fetus during perinatal period.

Study on the relationship between serum high density lipoprotein and Pi-deficiency syndrome in patients with coronary heart disease.

OBJECTIVE: To explore the relationship of Pi-deficiency syndrome in TCM with the change of serum high density lipoprotein (HDL) in blood lipid metabolic disorder. METHODS: Sixty-eight patients with confirmed coronary heart disease (CHD) were selected for TCM syndrome typing into Pi-deficiency (PD) group and non-Pi-deficiency (NPD) group. Routine blood lipids and serum lipoprotein electrophoretogram (SLPG) were determined in all patients to analyze the total content of HDL and its relative contents of sub-components HDL(1-5), as well as their relation with PD syndrome. Besides, a healthy control group (62 cases) was set up. RESULTS: The level of serum HDL-C was lowered, SLPG abnormality rate increased in the patients with CHD, with total HDL and the relative contents of subcomponent HDL(1) and HDL(3) significantly lower than those in the healthy control group (P<0.01). The total HDL, HDL(1) and HDL(3) in the PD group were also lower than those in the NPD group (P<0.05, P<0.01). CONCLUSION: Serum HDL and its sub-components showed a definite relation with TCM PD syndrome type, therefore, further exploring the granular specificity of HDL and its sub-components as well as their influence on reverse cholesterol transport (RCT) may hopefully provide clues for developing RCT regulatory Chinese new drugs and for CHD prevention and treatment.

[Some insights into clinical detection and analysis of serum lipoprotein for studies on integrated traditional Chinese and western medicine].

Dyslipoproteinemia is correlated with the occurrence and development of atherosclerosis and cardiocerebral vascular diseases. The metabolism of serum lipoprotein, however, is a complicated and ordered metabolic process. On one hand, every organ, tissue and even cell of the body participates in and affects the state of serum lipoprotein dynamic balance (SLDB) in different degrees. On the other hand, SLDB is a direct factor for maintaining the normality of whole vascular system, especially the vascular endothelium system. The serum lipoprotein dynamic imbalance, as an inducement or even etiological factor, can bring about various clinical diseases. Therefore, integrated analysis is needed to appropriately assess the state of SLDB. It is suggested that serum lipoprotein dynamic imbalance syndrome should be the key risk factor for those related diseases. Serum lipoprotein electrophoretogram can ideally express the state of SLDB and be taken as a new index for cognizing the serum lipid metabolism and the function of speen-qi to distribute Jing (Essonse) in the integrated traditional Chinese and western medicine. Practice has showed that concrete integration and bilateral development should be one of the main tasks in current researches of integrated traditional Chinese and western medicine.
