Hepatoprotective activity of Zha Xun and its different solvent-eluting components / 药学学报

A pharmacophore-based study was conducted to investigate the therapeutic activity of the traditional Tibetan medicine Zha Xun (ZX) in liver diseases. In the present study, the protective effect of ZX on the acute liver injury induced by concanavalin A (ConA) and 0.15% carbon tetrachloride (0.15% CCl4) in ICR mice was evaluated, and the results showed that ZX significantly reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the ConA-induced acute immune liver injury model and the CCl4-induced acute oxidative liver injury model (P < 0.05). Subsequently, the protective effects of aqueous, 95% ethanol, 60% ethanol and 30% ethanol eluting fractions of ZX, and fulvic acid, the main water-soluble constituent of ZX, were evaluated against acute oxidative liver injury induced by 0.15% CCl4 in mice. The results showed that different solvent-eluting fractions of ZX showed certain hepatoprotective activities, among which the aqueous extract of ZX and 30% ethanol extract of ZX significantly reduced the serum levels of ALT, AST, and lactate dehydrogenase (LDH) in mice (P < 0.05), and the serum levels of LDH in mice were significantly reduced by fulvic acid (P < 0.05), which showed significant hepatoprotective activity. The protective activities and preliminary mechanisms of the total extract of ZX, the aqueous extract of ZX, the 30% ethanol extract of ZX, and fulvic acid against hepatocellular injury in vitro were further evaluated by using the H2O2-induced hepatocellular injury model. The results showed that the components could significantly inhibit H2O2-induced hepatocellular injury, reduce the levels of ALT, alkaline phosphatase (ALP), and LDH, improve the survival rate of hepatocellular cells, and reduce the content of intracellular reactive oxygen species (ROS) in cell culture. At the same time, it can inhibit hepatocyte apoptosis by increasing the expression ratio of Bcl-2/BAX protein and decreasing the expression ratio of cleaved caspase-3/pro caspase-3 protein. The present study showed that ZX has clear hepatoprotective activity in vitro and in vivo, and the different solvent elution fractions of ZX showed certain hepatoprotective activity, among which the aqueous extract of ZX, 30% ethanol extract of ZX had better hepatoprotective activity, and the activity of 60% ethanol extract of ZX was stronger than that of 95% ethanol extract of ZX. The activity of ZX and its water-soluble elution site exerted hepatoprotective effects by inhibiting hepatocyte apoptosis and oxidative stress. The animals used in this experiment and related disposal meet the requirements of animal welfare, and have been reviewed and approved by the Laboratory Animal Management and Use Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences (approval number: 00004018).

UK national chronic hypoparathyroidism audit.

OBJECTIVES: Individuals with chronic hypoparathyroidism may experience suboptimal medical care with high frequency of unplanned hospitalisation and iatrogenic harm. In 2015 the European Society for Endocrinology published consensus guidelines on the management of chronic hypoparathyroidism. We set out to audit compliance with these guidelines. METHODS: Using these recommendations as audit standards we worked with the Society for Endocrinology and Parathyroid UK to conduct a national audit of management of chronic hypoparathyroidism in the United Kingdom. Endocrine leads in 117 endocrine departments were invited to participate in the survey by completing a data collection tool on up to 5 sequential cases of chronic hypoparathyroidism seen in their outpatient clinics in the preceding 12 months. Data were collected on 4 treatment standards and 9 monitoring standards. Data on hospitalisations and Quality of Life monitoring were also collected. RESULTS: Responses were received from 22 departments giving a response rate of 19%, concerning 80 individual cases. The mean age of subjects was 48.4 years. The main findings were that the commonest cause of hypoparathyroidism was post surgical (66.3%). Treatments taken by the group included activated vitamin D analogues (96.3%), oral calcium salts (66.3%), vitamin D supplements (17.5%), thiazide diuretics (5%) and rhPTH1-34 (1.3%). Compliance with the audit standards varied between 98.8% and 60% for the treatment standards and between 91.3% and 20% for the monitoring standards. Some of the areas of weakness revealed include low rates of 24 h urinary calcium excretion monitoring, serum magnesium monitoring and low rates of renal imaging where indicated. In addition and importantly, 16.3% of subjects had experienced at least one hospital admission in the preceding 12 months. CONCLUSION: We conclude that further improvements in the UK national standard of management of chronic hypoparathyroidism should be made and that this will benefit both quality of life, morbidity and potentially mortality in this group of patients.

Objective: To observe the clinical efficacy of umbilical therapy with herbal cakes made of Ge Gen Qin Lian Tang prescription of different dosages in treating damp-heat diarrhea in young children. Methods: Seventy-two kids with diarrhea of damp-heat pattern were recruited and divided into a high-dosage group and a low-dosage group using the random number table method, with 36 cases in each group. They all received conventional antidiarrheal treatment and umbilical application with herbal cakes. However, the herbal cakes for the high-dosage group were made of the mixture of Ge Gen Qin Lian Tang powder and water, and those for the low-dosage group consisted of 10％ Ge Gen Qin Lian Tang powder and 90％ auxiliary materials (corn starch) plus water. The treatment duration was 3 d. The clinical efficacy, antidiarrheal rate, effective rate for symptoms and signs of traditional Chinese medicine (TCM), TCM symptoms score, and safety indicators were compared between the two groups. Results: After the treatment, the TCM symptoms scores dropped significantly in both groups (P<0.01) and were lower in the high-dosage group than in the low-dosage group (P<0.05). The clinical efficacy was more significant in the high-dosage group than in the low-dosage group after the treatment, and the between-group difference was statistically significant (P<0.05); the antidiarrheal rate was markedly higher in the high-dosage group than in the low-dosage group (P<0.05). Regarding the TCM symptoms and signs, the high-dosage group showed better results in improving the greasy and yellowish tongue coating, bowel movement frequency, watery excrement, short and dark urine, red tongue body, red anus, vomiting, bowel sounds, and abdominal bloating compared with the low-dosage group, and the between-group differences were statistically significant (P<0.01). Conclusion: Umbilical therapy with herbal cakes made of Ge Gen Qin Lian Tang is safe, reliable, and effective in treating damp-heat diarrhea in young children; the high-dosage herbal cakes produce more significant efficacy than the low-dosage ones and are worth further investigation.

Metabolite production during transformation of 2,4,6-trinitrotoluene (TNT) by a mixed culture acclimated and maintained on crude oil-containing media.

Metabolites formed during 2,4,6-trinitrotoluene (TNT) removal by a mixed bacterial culture (acclimated and maintained on crude oil-containing medium and capable of high rates of TNT removal) were characterized. In resting cell experiments in the absence of glucose, 46.2 mg/l TNT were removed in 171 h (87.5% removal), with a combined total formation of 7.7 mg/l amino-4,6-dinitrotoluene (ADNT) and 0.3 mg/l 4,4'-azoxytetranitrotoluene and 2',4-azoxytetranitrotoluene, leaving 70% of the initial TNT unaccounted for. In the presence of glucose, resting cells removed 45.4 mg/l TNT in 49 h (95.5% removal), with 9.1 mg/l ADNT and 2.4 mg/l azoxy compounds being produced, leaving 70.3% of the TNT unaccounted for. Growing cells (glucose present) were capable of removing 44.2 mg/l TNT within 21 h (97.9% removal), with the concomitant formation of 1.8 mg/l ADNTs and 2.2 mg/l azoxy compounds. Denitrated TNT in the form of 2,6-dinitrotoluene was also produced in growing cells with a maximum amount of 1.31 mg/l after 28 h, followed by a slight decrease with time, leaving 88.5% of the initial TNT unaccounted for after 171 h. Radiolabeled (14)C-TNT studies revealed 4.14% mineralization after an incubation period of 163 days with growing cells.

Biodegradation of the nitramine explosives hexahydro-1,3,5-trinitro-1,3,5-triazine and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine in cold marine sediment under anaerobic and oligotrophic conditions.

The in situ degradation of the two nitramine explosives, hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), was evaluated using a mixture of RDX and HMX, incubated anaerobically at 10 degrees C with marine sediment from a previous military dumping site of unexploded ordnance (UXO) in Halifax Harbor, Nova Scotia, Canada. The RDX concentration (14.7 mg.L-1) in the aqueous phase was reduced by half in 4 days, while reduction of HMX concentration (1.2 mg.L-1) by half required 50 days. Supplementation with the carbon sources glucose, acetate, or citrate did not affect the removal rate of RDX but improved removal of HMX. Optimal mineralization of RDX and HMX was obtained in the presence of glucose. Using universally labeled (UL)-[14C]RDX, we obtained a carbon mass balance distributed as follows: CO2, 48%-58%; water soluble products, 27%-31%; acetonitrile extractable products, 2.0%-3.4%; and products covalently bound to the sediments and biomass, 8.9% (in the presence of glucose). The disappearance of RDX was accompanied by the formation of the mononitroso derivative hexahydro-1-nitroso-3,5-dinitro-1,3,5-triazine (MNX) and formaldehyde (HCHO) that subsequently disappeared. In the case of HMX, mineralization reached only 13%-27% after 115 days of incubation in the presence or absence of the carbon sources. The disappearance of HMX was also accompanied by the formation of the mononitroso derivative. The total population of psychrotrophic anaerobes that grew at 10 degrees C was 2.6 x 10(3) colony-forming units.(g sediment dry mass)-1, and some psychrotrophic sediment isolates were capable of degrading RDX under conditions similar to those used for sediments. Based on the distribution of products, we suggest that the sediment microorganisms degrade RDX and HMX via an initial reduction to the corresponding mononitroso derivative, followed by denitration and ring cleavage.

Tuina Therapy for Prolapsed Lumbar Intervertebral Disc / 针灸推拿医学（英文版）

Recurrent low back pain and reflex sciatica of lower limbs are the two leading symptoms of prolapsed lumbar intervertebral disc, which can be confirmed in the history, symptoms, signs and imaging examination such as CT scan and MRI. It should be differentiated from those conditions characterized by lumbago and/or possible sciatica. Tuina was performed mostly on the Bladder Meridian,Gallbladder Meridian and Governor Vessel, as well as their acupoints such as Jiaji (Ex-B 2) points,Shenshu (BL 23), Dachangshu (BL 25), Yaoyangguan (GV 3), Huantiao (GB 30), Weizhong (BL 40),Chengshan (BL 57), Yanglingquan (GB 34) and Ashi points. Thumb-massaging manipulation, rolling manipulation, pulling manipulation, pressing manipulation, kneading manipulation and grasping manipulation are often performed.

High TNT-transforming activity by a mixed culture acclimated and maintained on crude-oil-containing media.

A mixed microbial culture originating from a petroleum-contaminated site and maintained on crude oil exhibited high 2,4,6-trinitrotoluene (TNT) transformation activity. Cultivation of the mixed culture in glucose-containing medium for 29 h resulted in almost complete transformation of 100 ppm TNT. TNT transformation was observed with both growing and resting cells. With subculturing, it was found that TNT could support growth of the mixed culture when supplied as sole carbon source, sole nitrogen source, or sole carbon and nitrogen source. The finding that a mixed microbial culture maintained on crude oil exhibited high TNT transformation activity without prior subculture on TNT-containing media is novel and may have potential practical applications in the bioremediation of munitions-contaminated soil and wastewater.
