Summarizing the literature of syndrome differentiation and treatment of alcoholic liver disease (ALD) with Traditional Chinese Medicine (TCM) in recent five years,to investigate the realization and the laws of prescribing in this disease from the perspective of selecting drugs and forming formulas of TCM. This article summarized the characteristics of formula selection in treating ALD,and summed up the treatment principle of ALD and the realization of main syndrome by the principle of 'learning syndrome from formula','correspondence of syndrome with for mula'. The results showed that promoting blood circulation for removing blood stasis,tonifying consumption,promoting diuresis and percolating dampness were the main principle of prevention and treatment of ALD in recent years,and blood stasis,qi asthenia and phlegmatic hygrosis were the major pathogenesis of ALD. According to studying the literature of TCM,it was can be seen that the present treatment of ALD was still in the exploratory stage of clinical observation,it lacked multi-center,randomized and control prospective study of large sample,and judgment of curative effect were disunity,and objective evaluation criteria was lacked. These questions were worth further exploration.

OBJECTIVETo study the changes in the levels of autophagy-related proteins, Atg1, Atg5, and Beclin1, in organophosphate-induced delayed neuropathy (OPIDN) caused by tri-ortho-cresyl phosphate (TOCP), and to investigate the molecular pathogenic mechanism of OPIDN.

METHODSThirty adult Roman hens were randomly and equally divided into control group and 1, 5, 10, and 21 d intoxication groups. Each hen in the intoxication group was administered TOCP by gavage at a single dose of 750 mg/kg, while each hen in the control group was administered the same volume of corn oil. The hens were killed at the corresponding time points, and their tibial nerves and spinal cords were collected. The levels of Atg1, Atg5, and Beclin1 in the tibial nerves and spinal cords were measured by immunoblotting.

RESULTSCompared with those in the control group, the levels of Atg1 in tibial nerves decreased by 29.8%, 64.4%, 43.5%, and 19.8% at 1, 5, 10, and 21 d, respectively, after intoxication ((P < 0.05); the levels of Atg5 in tibial nerves decreased by 36.8%, 49.6%, 51.2%, and 31.5% at 1, 5, 10, and 21 d, respectively, after intoxication (P < 0.05); the levels of Beclin1 in tibial nerves decreased by 68.5%, 66.3%, and 32.2% at 1, 5, and 10 d, respectively, after intoxication (P < 0.05). Compared with those in the control group, the levels of Atg1 in spinal cords decreased by 23.5%, 48.7%, and 20% at 1, 5, and 10 d, respectively, after intoxication (P < 0.05); the levels of Atg5 in spinal cords decreased by 32.7%, 51.5%, 47.3%, and 39.6% at 1, 5, 10, and 21 d, respectively, after intoxication (P < 0.05); the levels of Beclin1 in spinal cords decreased by 28.9%, 50.2%, 43.2%, and 28.3% at 1, 5, 10, and 21 d, respectively, after intoxication (P < 0.05).

CONCLUSIONThe intoxication of TOCP is associated with the significant changes in the levels of autophagy-related proteins in the nervous tissues of hens, which might be involved in the pathogenesis of OPIDN.

OBJECTIVETo investigate the effect of 2,5-hexanedione (HD) on degradation of low-molecular-weight neurofilaments (NF-L) in nervous tissue of rats, and to explore the molecular mechanism of n-hexane neuropathy.

METHODSFifty male Wistar rats were randomly divided into one-week poisoning group (n = 10), two-week poisoning group (n = 10), three-week poisoning group (n = 10), four-week poisoning group (n = 10), and control group (n = 10). In the four poisoning groups, a rat model of n-hexane neuropathy was established by intraperitoneal injection of HD (400 mg/kg/d). The change in the sciatic nerve ultrastructure of each rat was observed under an electron microscope. The progression of HD-induced peripheral neuropathy was evaluated using a gait scoring system. The degradation rates of NF-L in the sciatic nerve and spinal cord of each rat were measured by Western Blotting.

RESULTSThe rats showed decrease in muscle strength and abnormal gait after two weeks of HD poisoning and mild or moderate paralysis after four weeks of HD poisoning. The sciatic nerve showed degenerative change, according to electron microscope observation. Compared with the control group, the two-week poisoning group, three-week poisoning group, and four-week poisoning group had the NF-L degradation rates decreased by 25.8%, 70.4%, and 69.7%, respectively, in the supernatant fraction of sciatic nerve, and by 14.7%, 64.6%, and 67.3%, respectively, in the sediment fraction of sciatic nerve, all showing a significant difference (P < 0.01). Compared with the control group, the one-week poisoning group had the NF-L degradation rate decreased by 33.87% in the supernatant fraction of spinal cord, the four-week poisoning group had the NF-L degradation rate increased by 16.2% in the supernatant fraction of spinal cord, and the one-week poisoning group and two-week poisoning group had the NF-L degradation rates decreased by 46.3% and 13.0% in the sediment fraction of spinal cord, all showing a significant difference (P < 0.01).

CONCLUSIONHD poisoning significantly inhibits NF-L degradation in the sciatic nerve, which may be associated with NF degeneration and accumulation in the axons of patients with n-hexane neuropathy.

OBJECTIVETo study the effects of Zuogui Pill (, ZGP) and Yougui Pill (, YGP) on the expressions of brain-derived neurotrophic factor (BDNF) and cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signaling of axonal regeneration in the Lewis rats with experimental autoimmune encephalomyelitis (EAE), in order to explore the possible mechanism of ZGP and YGP on promoting axonal regeneration.

METHODSThe rats were randomly divided into normal control (NC), model (MO), prednisone acetate (PA), ZGP and YGP groups. The EAE model of rat was established by injecting antigen containing myelin basic protein (MBP)68-86. The brain and spinal cord were harvested on the 14th and 28th day post-immunization (PI), the protein and mRNA expression of BDNF and PKA in the brain and spinal cord of rats were detected by Western blot analysis and real-time quantitative polymerase chain reaction (PCR), and the cAMP levels were detected by using enzyme-immunoassay method.

RESULTS(1) On the 28th day PI, the mRNA expression of BDNF in brain white matter and spinal cord of rats in ZGP and YGP groups were up-regulated, especially in YGP group (P<0.05 or P<0.01). (2) On the 14th day PI, the cAMP levels in brain white matters significantly increased in PA and YGP groups compared with MO group (P<0.05 or P<0.01), and the cAMP level in YGP group was higher than that in ZGP group (P<0.05). The cAMP level in spinal cord also significantly increased in YGP group compared with MO, PA and ZGP groups, respectively (P<0.01). (3) On the 14th day PI, the PKA expression in spinal cord of rats in ZGP group was significantly decreased compared with MO and YGP groups, respectively (P<0.05). (4) On the 28th day PI, there was a positive correlation between cAMP and PKA expression in the brain white matter of YGP rats.

CONCLUSIONSThe results suggest that ZGP and YGP may promote axonal regeneration by modulating cAMP/PKA signal transduction pathway, but the targets of molecular mechanism of ZGP may be different from those of YGP.

A total of 100 HIN1 flu real-time-PCR positive throat swabs collected from fever patients in Zhejiang,Hubei and Guangdong between June and November 2009,were provided by local CDC laboratories.After MDCK cell culture,57 Influenza A Pandemic (H1N1) viruses were isolated and submitted for whole genome sequencing.A total of 39 HA sequences,52 NA sequences,36 PB2 sequences,31 PB1 sequences,40 PA sequences,48 NP sequences,51 MP sequences and 36 NS sequences were obtained,including 20 whole genome sequences.Sequence comparison revealed they shared a high degree of homology (96％～99％) with known epidemic strains (A/Califomia/04/2009(H1N1).Phylogenetic analysis showed that although the sequences were highly conserved,they clustered into a small number of groups with only a few distinct strains.Site analysis revealed three substitutions at loop 220 (221-228) of the HA receptor binding site in the 39 HA sequences:A/Hubei/86/2009 PKVRDQEG→PKVRDQEA,A/Zhejiang/08/2009 PKVRDQEG→PKVRDQER,A/Hubei/75/2009PKVRDQEG→PKVRDQGG,the A/Hubei/75/2009 was isolated from an acute case,while the other two were from patients with mild symptoms.Other key sites such as 119,274,292 and 294 amino acids of NA protein,627 of PB2 protein were conserved.Meanwhile,all the M2 protein sequences possessed the Ser32Asn mutation,suggesting that these viruses were resistant to adamantanes.Comparison of these sequences with other H1N1 viruses collected from the NCBI database provides insight into H1N1 transmission and circulation patterns.

Objective:To analyze the genetic etiology of idiopathic short stature(ISS) children, and to investigate the clinical characteristics of Noonan syndrome caused by PTPN11 gene mutation, and the response to recombinant human growth hormone(rhGH) as well.Methods:Genomic DNA was extracted from the peripheral blood of 232 ISS patients, and the genome was detected by whole exon sequencing. The gene variation was analyzed according to the guideline of American College of Medical Genetics and Genomics(ACMG), and clinical baseline data and follow-up data of rhGH treatment were collected from PTPN11 gene pathogenic patients.Results:Among 232 ISS patients, 6 were found to have PTPN11 pathogenic gene variants(c.1507G>C, c. 317A>G, c. 923A>G, c. 922A>G, c. 236A>G, c. 922A>G), diagnosed as Noonan syndrome. Together with 3 cases of Noonan syndrome patients(all PTPN11 gene variation C. 1510A>G) previously diagnosed in our hospital, the clinical characteristics of patients were analyzed. Among the 9 Noonan syndrome patients, 7 were boys and 2 were girls. The average age was 10.2(4.5, 14.7) years old, and their height standard deviation score was -3.06 SD(95% CI -2.29 SD--3.94 SD). Among them, 4 patients received rhGH treatment with an average treatment duration of 2.25(1.5, 3.5) years. After treatment, their height increased by 14.3(8.6, 23.9) cm, and the change in height standard deviation score improved by 0.21 SD(95% CI 0.12 SD-0.27 SD). Conclusion:Noonan syndrome has a wide range of clinical phenotypes. For children with short stature, heart defects and cryptorchidism, the possibility of Noonan syndrome should be considered. PTPN11 is the common pathogenic gene for Noonan syndrome, and genetic testing facilitates the early diagnosis, treatment, and follow-up prognosis of Noonan syndrome patients.

Objective:To analyze the cause and epidemiological characteristics of an outbreak of cutaneous anthrax in Caoxian County, Heze City, Shandong Province, and to provide scientific basis for anthrax prevention and control.Methods:Using on-site epidemiological investigation methods and the "Anthrax Epidemiological Case Investigation Form", case investigations were conducted based on the epidemiological contact history and close contacts of suspected anthrax cases reported by the national health care system ( n = 83). Scorched skin smears, diseased cattle tissues, soil samples from the slaughter site and smears from slaughter utensils were collected from cases for Real-time PCR testing and pathogenic bacteria isolation and culture, respectively. Anthrax determination criteria were carried out with reference to "Anthrax Diagnosis" (WS 283-2020). Results:A total of 13 cases of cutaneous anthrax were found in this outbreak, including 12 clinically diagnosed cases and one confirmed case (positive Real-time PCR test and isolation of a strain of Bacillus anthracis). The epidemiological investigation determined that the source of infection in this outbreak was diseased cattle, the transmission route was through slaughter of diseased cattle, contact with contaminated utensils and related cattle products, and the patients were mainly engaged in occupations related to cattle slaughter or cattle product collection and sale. A total of 84 samples were collected, including 13 skin scabs, 64 environmental samples and 7 beef samples. Thirty-six positive PCR tests were performed, with a positive rate of 42.86% (36/84). Among them, 100.00% (13/13) were positive for skin scab smear specimens, 29.69% (19/64) for environmental samples and 4/7 for beef samples. A total of 8 strains of Bacillus anthracis were isolated, including 6 environmental specimens, 1 suspected case and 1 beef strain, with an overall detection rate of 9.52% (8/84). Eighty-three close contacts were investigated. Thirteen households involved in the epidemic were disinfected by spraying (200 ml/m 2) with chlorine-containing disinfectant (5 000 mg/L), and a total of 40 households involved in the epidemic were disinfected, covering an area of about 10 765 m 2. Forty-five pieces of suspected contaminated clothing were burned and disposed of, and 152 pieces of kitchenware were soaked. Conclusions:Slaughter of infected cattle, contact with contaminated utensils and related cattle products are the main causes of this skin anthrax outbreak. Strengthening market supervision, deepening inter-animal epidemic prevention, carrying out publicity and education on anthrax prevention and control, and enhancing practitioners' awareness of disease prevention is the key to prevent anthrax from occurring.

Hypertension is a risk factor for a variety of cardiovascular diseases, which is an important public health problem in the world today. MiRNAs are a class of highly conserved non-coding small RNAs. In recent years, studies have found that miRNAs are involved in the occurrence and development of hypertension through a variety of ways, causing damage to the important target organs of hypertension, such as heart, brain and kidney. This article reviews the research progress of miRNA in hypertension in recent years, in order to clarify its role in the process of hypertension and target organ damage, and provide ideas for exploring new therapeutic targets of hypertension.
