Lysosomal membrane protein Sidt2 knockout induces apoptosis of human hepatocytes in vitro independent of the autophagy-lysosomal pathway / 南方医科大学学报

OBJECTIVE@#To explore the regulatory mechanism of human hepatocyte apoptosis induced by lysosomal membrane protein Sidt2 knockout.@*METHODS@#The Sidt2 knockout (Sidt2-/-) cell model was constructed in human hepatocyte HL7702 cells using Crispr-Cas9 technology.The protein levels of Sidt2 and key autophagy proteins LC3-II/I and P62 in the cell model were detected using Western blotting, and the formation of autophagosomes was observed with MDC staining.EdU incorporation assay and flow cytometry were performed to observe the effect of Sidt2 knockout on cell proliferation and apoptosis.The effect of chloroquine at the saturating concentration on autophagic flux, proliferation and apoptosis of Sidt2 knockout cells were observed.@*RESULTS@#Sidt2-/- HL7702 cells were successfully constructed.Sidt2 knockout significantly inhibited the proliferation and increased apoptosis of the cells, causing also increased protein expressions of LC3-II/I and P62(P < 0.05) and increased number of autophagosomes.Autophagy of the cells reached a saturated state following treatment with 50 μmol/L chloroquine, and at this concentration, chloroquine significantly increased the expressions of LC3B and P62 in Sidt2-/- HL7702 cells.@*CONCLUSION@#Sidt2 gene knockout causes dysregulation of the autophagy pathway and induces apoptosis of HL7702 cells, and the latter effect is not mediated by inhibiting the autophagy-lysosomal pathway.

A case of peripartum cardiomyopathy with recurrent ventricular fibrillation rescued by extracorporeal membrane oxygenation / 中华围产医学杂志

Peripartum cardiomyopathy (PPCM) often develops in the early postpartum period, especially within one month after delivery. However, in recent years, some cases of pregnancy-related cardiomyopathy with earlier or slightly later onset showed similar features with PPCM entirely. One patient with PPCM was admitted to the Department of Intensive Care Medicine of the First Affiliated Hospital of Bengbu Medical College on February 2022. After admission, the patient was exceptionally hemodynamically unstable and had repeated ventricular fibrillation. Apart from extracorporeal membrane oxygenation (ECMO) support, comprehensive treatment with cardiotonic agents and drugs to inhibit the "ventricular electric storm" was given. The cardiac structure and function were gradually improved. ECMO was successfully withdrawn on the 7th day after the onset of symptoms, and the patient was discharged after a full recovery. Early diagnosis and active intervention are the keys to improve the prognosis of patients with PPCM and avoid irreversible changes in cardiac structure.

Objective:To explore the teaching effect of hierarchical and phased teaching method on the teaching of neurosurgery interns.Methods:Thirty-five interns of the Department of Neurosurgery of The First People's Hospital of Liangshan Yi Autonomous Prefecture from July 2019 to March 2020 were selected as the control group, and received the traditional clinical teaching method. Another 34 interns from June 2020 to February 2021 were selected as the research group, and adopted the hierarchical and phased teaching method. The graduation examination results were compared, and the scores of mini-clinical evaluation exercise (Mini-CEX) scale before and after practice and the recognition of teaching methods by interns were compared. SPSS 24.0 was used for t test and chi-square test. Results:The results of theoretical knowledge of neurosurgery [(90.15±4.47) points], operation skills [(91.12±3.68) points] and clinical case analysis ability [(87.32±5.41) points] in the study group were higher than those in the control group [(85.26±5.19) points, (86.14±5.25) points and (80.94±4.26) points], and the differences were statistically significant ( P<0.001). The scores of Mini-CEX scale in the two groups after internship were both higher than those before internship ( P<0.001), which in the study group after internship were higher than those in the control group ( P<0.001). The recognition of the teaching method in improving the learning interest and enthusiasm, strengthening the ability to master knowledge, improving the ability to analyze and deal with clinical problems, improving the ability to combine theoretical knowledge with practice and improving the clinical thinking ability of interns in the study group were higher than those in the control group ( P<0.05). Conclusion:In the clinical teaching of neurosurgery interns, the application of hierarchical and phased teaching method can significantly improve the comprehensive assessment ability and professional quality of interns, and can also improve their recognition of this teaching method.

Lipid markers and targets of coronary artery disease based on lipidomics / 药学学报

Coronary artery disease is the leading cause of death worldwide, the coronary artery stenosis or occlusion caused by atherosclerosis leads to myocardial ischemia, hypoxia, or necrosis, that is main histopathological features of coronary artery disease. Atherosclerosis relates closely to abnormal lipid regulation, chronic inflammation, and endothelial dysfunction. Cardiac enzymes and high, low-density lipoprotein are currently used to diagnose a variety of coronary artery diseases, but the evidence is inadequate. Thus, new cardioprotective therapies are required to explore sensitive molecular markers for the prediction of cardiovascular events. Lipids have an important role in maintaining the myocardial cell structure as well as cardiac function. Lipidomics is a newly emerged discipline that studies lipids on a large scale. Recent advancements in lipidomics on coronary artery disease have shown that certain lipids, such as ceramide, sphingosine, lysophosphatidic acid, oxidized lipids, and so on, are associated with the clinical classification and characteristics of coronary artery disease. In addition, recent studies of lipid profiles of the cardiac, fat, liver, and other tissue samples in animal models also have provided a novel viewpoint. Given the increasing application of lipidomics techniques for coronary artery disease, we provide a review of lipidomics technology, sensitive lipid markers, recent studies of therapeutic targets, and drug discovery for coronary artery disease.

Phenotypes and ATP7B gene variants in 316 children with Wilson disease / 中华儿科杂志

Objectives: To summarize the clinical phenotypes and the variation spectrum of ATP7B gene in Chinese children with Wilson's disease (WD) and to investigate their significance for early diagnosis. Methods: Retrospective analysis was performed on the clinical data of 316 children diagnosed as WD in Guangzhou Women and Children's Medical Center during the period from January 2010 to June 2021. The general situations, clinical manifestations, lab test results, imaging examinations, and ATP7B gene variant characteristics were collected. The patients were divided into asymptomatic WD group and symptomatic WD group based on the presence or absence of clinical symptoms at the time that WD diagnosis was made. The χ2 test, t test or Mann-Whitney U test were used to compare the differences between groups. Results: Among the 316 children with WD, 199 were males and 117 were females, with the age of 5.4 (4.0, 7.6) years at diagnosis; 261 cases (82.6%) were asymptomatic with the age of 4.9 (3.9, 6.4) years; whereas 55 cases (17.4%) were symptomatic with the age of 9.6 (7.3, 12.0) years. The main symptoms invloved liver, kidney, nervous system, or skin damage. Of all the patients, 95.9% (303/316) had abnormal liver function at diagnosis; 98.1% (310/316) had the serum ceruloplasmin lever lower than 200 mg/L; 97.7% (302/309) had 24-hour urine copper content exceeding 40 μg; only 7.4% (23/310) had positive corneal K-F rings, 8.2% (23/281) had abnormal MRI signals in the lenticular nucleus, and all of them had symptoms of damage in liver, kidney or nervous system. Compared with the group of symptomatic WD, asymptomatic group had higher levels of serum alanine aminotransferase and lower levels ceruloplasmin and 24-hour urine copper [(208±137) vs. (72±78) U/L, (55±47) vs. (69±48) mg/L, 103 (72, 153) vs. 492 (230, 1 432) μg; t=9.98, -1.98, Z=-4.89, all P<0.001]. Among the 314 patients completing genetic sequencing, a total of 107 mutations in ATP7B gene were detected, of which 10 are novel variants, and 3 cases (1.0%) had large heterozygous deletion (exons 10 to exon 11) in ATP7B gene. The percentage of missense mutation in asymptomatic WD children was significantly higher than that in symptomatic WD (81.5% (422/518) vs. 69.1% (76/110), χ²=8.47, P<0.05). WD patients carrying homozygous variant of c.2 333G>T had significantly low levels of ceruloplasmin than those not carrying this variant ((23±5) vs. (61±48) mg/L, t=-2.34, P<0.001). Conclusions: The elevation of serum ALT is an important clue for early diagnosis of WD in children, while serum ceruloplasmin and 24-hour urine copper content are specific markers for early diagnosis of WD. In order to confirm the diagnosis of WD, it is necessary to combine the Sanger sequencing with multiplex ligation-dependent probe amplification or other testing technologies.

Epidemiological features of severe acute respiratory syndrome coronavirus 2 infection in children in Shijiazhuang, China: an analysis of 133 cases / 中国当代儿科杂志

OBJECTIVE@#To study the epidemiological features of children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Shijiazhuang, China.@*METHODS@#Based on the information officially announced on the official website of the Health Commission of Hebei Province, epidemiological data were collected from 133 children, aged 0-18 years, who were diagnosed with SARS-CoV-2 infection in Shijiazhuang from January 2 to January 30, 2021. A statistical analysis was performed for general status, regional distribution, presence or absence of clusters, and results of SARS-CoV-2 nucleic acid tests.@*RESULTS@#Among the 133 children with SARS-CoV-2 infection, there were 65 boys and 68 girls, with a male/female ratio of 0.96:1. The youngest age of onset was 3 months and 7 days, and the mean age of onset was (9±5) years. Of all the 133 children, 90(67.7%) were the first confirmed case of SARS-CoV-2 infection among their family members. Of all the children, 108(81.2%) came from the Gaocheng District in Shijiazhuang, among whom 38(28.6%) were from Xiaoguozhuang Village where the first patient with a confirmed diagnosis lived. SARS-CoV-2 nucleic acid test at week 2 after the outbreak showed positive results in 88 children (66.2%), and only 5 children had clinical symptoms before positive SARS-CoV-2 results were obtained. Of all the 133 children, 19(14.3%) were found positive in the first SARS-CoV-2 nucleic acid test after the outbreak, and 70(52.6%) had positive results for ≥4 times. There were 98 school students with infection, among whom 74(75.5%) were the first confirmed case in their family, and among 35 non-school students, 16(45.7%) were the first confirmed case in their family (@*CONCLUSIONS@#Among the children confirmed with SARS-CoV-2 infection in Shijiazhuang, there is a high proportion of children who are the first confirmed case in their family, and the children are mainly distributed in the rural areas of Gaocheng. Most of these children are students, so the prevention and control of cluster infection in schools should be taken seriously. There are often no symptoms before SARS-CoV-2 nucleic acid test, with a low positive rate of the first nucleic acid test, which increases the difficulty of early discovery of the epidemic.

Systematic review of efficacy and safety of Angong Niuhuang Pills in adjuvant treatment of cerebral hemorrhage / 中国中药杂志

To systematically review the efficacy and safety of Angong Niuhuang Pills in adjuvant treatment of cerebral hemorrhage. CNKI, VIP, Wanfang, CBM, PubMed, EMbase, Cochrane Library were retrieved to collect the randomized controlled trial(RCT) from the time of database establishment to November 2020. Two researchers screened out the literatures and extracted the data according to the inclusion and exclusion criteria. RevMan 5.3 software was used for Meta-analysis. A total of 13 RCTs were included, involving 1 196 patients with cerebral hemorrhage, with 599 in the treatment group and 597 in the control group, and all of them were treated with internal medicine. The results of Meta-analysis showed that compared with conventional therapy, the combined administration with Angong Niuhuang Pills could improve the effective rate in patients with cerebral hemorrhage(RR=1.25, 95%CI[1.18, 1.34], P<0.000 01), the National Institutes of Health stroke scale(NIHSS)score(MD=-5.18, 95%CI[-8.12,-2.23], P=0.000 6) and Glasgow coma scale(GCS) score(MD=1.12, 95%CI[0.46, 1.78], P=0.000 9), activity of daily living(ADL)(MD=15.70, 95%CI[14.05, 17.36 ], P<0.000 01), reduce the malondialdehyde(MDA)(MD=-1.73,95%CI[-2.81,-0.64],P=0.002), but with no statistically significant difference in hematoma volume changes between the two groups. In terms of safety, the combined administration with Angong Niuhuang Pills reduced the incidence of adverse reactions compared with the single administration of conventional therapy(RR=0.40, 95%CI[0.28, 0.57], P<0.000 01), with no serious adverse events. The existing clinical study evidences show that Angong Niuhuang Pills had a good effect in adjuvant treatment of cerebral hemorrhage, and can improve the treatment efficacy, activity of daily living and symptoms of neurological deficits, and reduce oxidative stress, with a higher safety. However, the methodological quality of the included studies is not high, so the above conclusions still need to be verified with more high-quality studies.

Effect of modified Buyang Huanwu Decoction on hemorrhagic transformation after rt-PA intravenous thrombolysis in patients with super early cerebral infarction / 中国中药杂志

To study the effect of modified Buyang Huanwu Decoction on the hemorrhagic transformation after intravenous thrombolysis of recombinant tissue type plasminogen activator(rt-PA) in patients with super early(onset time<4. 5 h) cerebral infarction. From March 2016 to July 2018,at the brain disease zone of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine,212 cases of super early cerebral infarction were selected and divided into two group according to the randomized complete blocks designs: control group(106 cases) and traditional Chinese medicine group(106 cases). The control group was treated with rt-PA intravenous thrombolysis,while the traditional Chinese medicine group was treated with modified Buyang Huanwu Decoction in addition to the therapy of the control group. Both groups were treated for 14 days. Neurological deficit score,serum matrix metalloproteinase-9(MMP-9),neuron specific enolase(NSE),vascular endothelial growth factor(VEGF) and plasma cellular fibronectin(c-FN) levels,the incidence of hemorrhagic transformation,clinical efficacy and adverse drug reactions before and after treatment were compared between the two groups. According to the findings,at the 14 thday after treatment,the rank sum test of the grade data showed that the clinical efficacy of the traditional Chinese medicine group was better than that of the control group(Z =-2. 033,P = 0. 042); on the basis of χ2 test,the total efficiency of the traditional Chinese medicine group was higher than that of the control group(χ2= 4. 895,P =0. 027); the hemorrhagic transformation rate of the traditional Chinese medicine group was lower than that of the control group within14 days of treatment(χ2= 3. 962,P = 0. 047). MMP-9 levels in the traditional Chinese medicine group were lower than those in the control group at the 3 rd,5 th,7 th,10 th,14 thd after treatment(t =-2. 474,-3. 022,-5. 163,-6. 998,-9. 821; P = 0. 014,0. 003,0,0,0). The improvement of c-FN,NSE,VEGF and NIHSS scores in the traditional Chinese medicine group was superior to that of the control group after 14 days of treatment(t =-2. 343,-3. 187,-2. 129,-3. 105; P = 0. 020,0. 002,0. 034,0. 002). No obvious adverse reactions of modified Buyang Huanwu Decoction were observed during 14 days of treatment. Modified Buyang Huanwu Decoction could reduce the expressions of MMP-9,c-FN,NSE and VEGF after rt-PA intravenous thrombolysis in patients with super early cerebral infarction,and decrease the hemorrhagic transformation rate after thrombolysis,with high safety.

Relationship between PI3K/Akt signal and its downstream pathway and cardiovascular disease / 中国药理学与毒理学杂志

A growing number of studies show that drug and non-drug means can be activated phosphatidyl inositol-3-kinase serine/threonine kinase(PI3K/Akt signaling pathway)in the beginning of reperfusion, and make its downstream fork protein transcription factor O3a (FoxO3a) phosphorylation, and then promote cell survival and reduce the apoptosis so as to alleviate the symptoms of myocardial ischemia.In this paper,the role of PI3K/Akt and FoxO3a effector in myocardial ischemia was reviewed, and illustrated the role of PI3K/Akt/FoxO3a signaling pathway in myocardial ischemia.

Effects of lutein on viability of breast cancer cells / 中国病理生理杂志

AIM:To investigate the effect of lutein on the viability of breast cancer cells and its possible mech -anism.METHODS:The human breast cancer T47D cells were divided into control group and lutein(6.25,12.5,25,50 mg/L)treatment groups.The effect of lutein on the viability of T47D cells was measured by MTT assay.The mRNA ex-pression of nuclear factor erythroid 2-related factor 2(Nrf2),glutathione peroxidase 1(GPx1)and superoxide dismutase 2 (SOD2)was detected by RT-qPCR.Fluorescent probes DCFH-DA was used to determine the production of reactive oxygen species(ROS).The protein expression of Nrf2 and p65 was determined by Western blot.RESULTS: The MTT results showed that lutein inhibited T47D breast cancer cell viability in a dose-and time-dependent manner.The RT-qPCR results showed that the mRNA levels of Nrf2, GPx1 and SOD2 were higher in lutein treatment groups than those in the control group(P<0.05),and with the increased concentrations and extension of intervention time of lutein, the relative mRNA levels were all increased.The ROS levels were significantly decreased in the lutein-treated groups(P<0.05).The results of Western blot demonstrated that the protein expression of Nrf 2 was significantly increased(P<0.05), and p65 protein was decreased(P<0.05)in a dose-dependent manner with lutein treatment for 48 h.CONCLUSION: Lutein signifi-cantly inhibits the viability of breast cancer cells,and the inhibition roles may be related to up-regulation of the expression of Nrf2,antioxidant enzymes GPx1 and SOD2 mRNA expression and down-regulation of oxidative stress,thus blocking the NF-κB signaling pathway.

Comparison of safe duration of apnea and intubation time in face mask ventilation with air versus 100% oxygen during induction of general anesthesia / 南方医科大学学报

<p><b>OBJECTIVE</b>To compare the safe duration of apnea and intubation time between face mask ventilation with air and 100% oxygen during induction of general anesthesia.</p><p><b>METHODS</b>Eighty adult patients with ASA class I or II without predicted difficult airways were scheduled for elective surgery under general anesthesia. The patients were randomized to receive anesthesia induction with preoxygenation [Group 1, n=40, fraction of inspired oxygen (FiO)=1] or without preoxygenation (Group2, n=40, FiO=0.21). Two experienced anesthesiologists performed the mask ventilation and tracheal intubation during induction, and the assistants adjusted the oxygen concentration and recorded the pulse oxygen saturation (SpO) and other variables. The cases where SpOdecreased to below 90% before accomplishment of intubation were considered unsuccessful, and mask ventilation with 100% oxygen was given. After tracheal intubation, mechanical ventilation was not initiated until the SpOdecreased to 90%. The number of unsuccessful cases, the safe duration of apnea and intubation time were recorded in the two groups.</p><p><b>RESULTS</b>There was no unsuccessful case in either groups. The safe duration of apnea was 469.5∓143.0 s in Group 1 and 63.6∓20.0 s in Group 2, and the intubation time was 34.4∓12.6 s and 32.8∓9.6 s, respectively. The safe duration of apnea was significantly longer than the intubation time in both groups (P<0.01). The intubation time and the number of cases with SpO≥90% before completion of tracheal intubation were similar between the two groups. The safe duration of apnea was significantly shorter in Group 2 than in Group 1 (P<0.01) and was correlated with the body mass index of the patients (P<0.05).</p><p><b>CONCLUSION</b>Anesthesia induction without preoxygenation can provide sufficient time for experienced anesthesiologists to complete tracheal intubation.</p>

Lipoic Acid Combined with Epalrestat versus Lipoic Acid in Treating Diabetic Peripheral Neuropathy:A Meta-analysis / 中国医学科学院学报

Objective To compare the clinical effectiveness of lipoic acid combined with epalrestat versus lipoic acid in treating diabetic peripheral neuropathy(DPN). Methods Randomized controlled trials(RCTs) and clinical controlled trials on lipoic acid versus epalrestat for DPN before February 2016 were searched through five databases:CNKI,CBM,VIP,Wanfang,and PubMed. The quality of the included trials were assessed using Cochrane software and Jadad scores. Data were analyzed with Review Manager 5.3 software. Results Nine studies were included in the analysis. Meta analysis showed that the lipoic aid monotherapy was significantly inferior to lipoic acid-epalerestat combination therapy [RR=0.58,95%Cl(0.47,0.71),P<0.00001]. Inferiority of the lipoic acid monotherapy was also shown in nerve conduction velocity with WMDs of-4.94 [95%Cl(-7.41,-2.46),P<0.0001] for median motor nerve conduction velocity(MNCV),-5.08 [95%Cl(-7.68,-2.49),P=0.0001] for peroneal MNCV,-4.24 [95%Cl(-6.20,-2.29),P<0.0001] for median sensory nerve conduction velocity(SNCV),and-3.66 [95%Cl(-5.02,-2.31),P<0.00001] for peroneal SNCV. Sensitivity analysis showed that the results were robust. However,the included trials were limited by simple design,few subjective indicators,and short follow-up time. Conclusions Lipoic acid combined with epalrestat is better than lipoic acid alone in the treatment of DPN,as well as the MNCV and SNCV of median or peroneal nerve. Due to the low quality of the included studies,high-quality RCTs are warranted to validate the results.

Effect of Tetramethylpyrazine on IL-8,IL-12 and IL-33 Levels in Serum and MMP-10 and NF-κB Protein Expression in Joint Synovial Tissues in Rats with Collagen-induced Arthritis / 医药导报

Objective To observe the effect of tetramethylpyrazine (TMP) on serum interleukin 8 (IL-8),interleukin 12 ( IL-12) and interleukin 33 ( IL-33) levels and MMP-10 and NF-κB protein expression in joint synovial tissues in rats with collagen-induced arthritis ( CIA) ,and further to investigate the mechanism for treating rheumatoid arthritis. Methods Rats were randomly divided into normal control group( n=10) ,model control group,dexamethasone group,low-dose of TMP and high-dose of TMP groups ( n=9 each) . The CIA model was established in all the groups except for the normal control group. Rats of dexamethasone group were give 2 mg.kg-1 of dexamethasone;Rats of low-dose and high-dose of TMP group were given 50,100 mg.kg-1 of TMP, respectively.The toe volume and arthritis index (AI) were used to evaluate joint inflammation. The levels of IL-8,IL-12 and IL-33 in the serum of rats were detected by ELISA. The expression levels of MMP-10 and NF-κB in joint synovial were detected by Western blotting. Results Compared with CIA group,the toe volume and AI were significantly reduced in high-dose of TMP groups and dexamethasone groups,and levels of IL-8,IL-12 and IL-33 and the expression levels of MMP-10 and NF-κB were decreased significantly (P0.05). Conclusion TMP at 100 mg.kg-1 showed obvious inhibition on CIA rats. The mechanism may be correlated to balancing the effect of proinflammatory factor and anti-inflammatory cytokines,improving immune function in rats,reducing joint synovial inflammation,and alleviating the destruction of the articular cartilage.

OBJECTIVE ToinvestigatethepossibleprotectiveeffectofTripterygiumwilfordiipolyg-lycoside (TWP ) on experi mental diabetic nephropathy (D N ) rats and its possible mechanis m. METHODS Thediabeticmodelwasinducedbyasingleintraperitonealinjectionofstreptozotocin (STZ)65 mg·kg -1 .Three weeks after modeling,TWP 4.5,9.0 and 1 8.0 mg·kg -1 was ig given to rats,once daily,for 8 consecutive weeks.During the experiment,the changes of body mass,hair, mental health of rats were observed.Two days before the end of the experi ment,the rats were placed into metabolic cages to collect 24 h urine in order to detect 24 h urinary albu min excretion rate (UAER). The rats were given TWP for 8 weeks and anesthetized with 1 0%chloral hydrate.The blood was collect-ed fro m the heart and centrifuged,seru m creatinine and urine creatinine were measured,and creatinine clearance (Clcr)was calculated.Blood urea nitrogen (BUN)and the serum catalase (CAT)activity were tested by optical method while the level of seru m superoxide oxygen anion(O2÷)was tested by col-orimetry.The level of malondialdehyde(MDA)was determined by thiobarbituric acid condensation,and glutathione peroxidase (GSH-Px)activity was tested by colorimetry.The right kidney was HE stained to observepathologicalchanges.RESULTS Comparedwithnormalcontrolgroup,theratsinmodel control group developed polydipsia,polyuria,polyphagia,body mass loss,unresponsiveness,brown hair,pale tail and apathy clammy.Besides,blood glucose,BUN and 24 h UAER were significantly higher (P<0.01 ),but Clcr was lower (P<0.01 ).The activity of serum CAT and GSH-Px in renal tissue was significantly lower(P<0.01 ),while the level of serum O2÷ and MDA in the renal tissue was significantly higher(P<0.01 ).Compared with model control group,TWP 9.0 and 18.0 mg·kg -1 could improve the general condition of rats.BUN and 24 h UAER were obviously reduced(P<0.01 ),Clcr and serum CAT were increased obviously(P<0.01 ),the level of MDA and O2÷ were reduced obviously(P<0.01 ),and GSH-Px level was increased(P<0.01 ).TWP 9.0 and 18.0 mg·kg -1 could significantly im-prove the renal histopathological changes of rats.TWP 4.5 mg·kg -1 had no significant effect on the aboveindicators.CONCLUSION TWPhasprotectiveeffectontherenalfunctionofexperimentalDN rats.The mechanis m may be related to inhibition of the oxidative stress and enhance ment of the body antioxidant capacity.

Retrospective analysis of clinical and epidemiological characteristics of hand-foot-and-mouth disease deceased cases in Zhejiang Province / 中华儿科杂志

<p><b>OBJECTIVE</b>To understand the clinical and epidemiological characteristics of hand-foot-and-mouth disease (HFMD) deceased cases.</p><p><b>METHOD</b>Information of demographics, diagnosis and treatment, clinical symptoms and signs, laboratory test results, and epidemiological contact history of 72 HFMD cases who died between May 2008 and September 2011, in Zhejiang Province, were collected and analyzed.</p><p><b>RESULT</b>The average age of the 72 cases was 1.8 years, 45 were males, accounting for 62.5%, 63 (87.5%) of the cases were scattered children. Eighteen counties reported 2 or more deaths, accounting for 46.1% (18/39) among the counties where the deaths were reported. The deaths occurred mainly in April to August, the peak occurred in May and June. Fever (98.4%, 63/64) and rash (95.1%, 58/61) were the most common symptoms, but the rash was not obvious at the first diagnosis. Fever occurred before the rash (79.0%, 49/62), persisted for 4 days in average. Vomiting (71.9%, 46/64), dyspnea (65.6%, 42/64), cyanosis (53.1%, 34/64) and impaired consciousness (51.6%, 33/64) were often seen among the cases; 53.1% (34/64) cases went to see the doctor on the first day, but 82.5%(52/63)cases were misdiagnosed. Time to diagnosis of HFMD was in average 3 days. About 3 to 4 days after the onset, the disease deteriorated sharply, deaths occurred within 1 day after admission in 78.9%(45/57)of the deceased cases; 85.0% (34/40) cases had high white blood cells level, mainly neutrophils increased, the ratio of neutrophil was more than 70% in 55.6% (15/27) of cases. Enterovirus 71 (EV71) infection was found in 93.3% (56/60) cases, the deceased cases often died of pulmonary hemorrhage (42.9%, 21/49) and encephalitis (34.7%, 17/49). The sanitary conditions of the cases' family were poor (65.5%, 36/55), but 73.3% (33/45) cases had no exposure history.</p><p><b>CONCLUSION</b>The HFMD deceased cases were mostly younger aged boys, scattered children, nonlocal-residents, and had poor sanitation. They were often infected with EV71, had high fever but had no typical rash, no clear exposure history, they had increased leukocyte, and were often misdiagnosed. Three or 4 days after onset, the disease deteriorated abruptly, most cases died within 1 week after onset. To decrease the HFMD mortality, early detection of severe cases should be stressed, and relative measures should be taken. The guardian should be aware of having good sanitary situation and healthy habits.</p>

Treating oligospermia patients of Shen-essence deficiency syndrome by 3 different treatment programs: a clinical observation / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To compare the clinical efficacy of 3 different treatment programs for oligospermia patients of Shen-essence deficiency syndrome (SEDS).</p><p><b>METHODS</b>Totally 450 male patients were randomly assigned to 3 groups, i.e., the treatment group, the control group 1, and the control group 2, 150 in each group. Patients in the treatment group were treated by Bushen Yijing Decoction (BYD), tamoxifen tablet (TT), Licorzine Capsule (LC), and Vitamin E Soft Capsule (VESC). Those in the control group 1 were treated by BYD, LC, and VESC. Those in the control group 2 were treated by TT, LC, and VESC. All patients were treated for 3 months. Their pregnant rates were compared. Clinical efficacies of each Chinese medical symptom and sperm parameters [sperm density, grade a sperm motility rate, grade (a + b) sperm motility rate, grade (a + b + c) sperm motility rate, and normal sperm morphology rate] were compared before and after treatment.</p><p><b>RESULTS</b>At 3 months after treatment 61 patients were pregnant in the treatment group, 36 patients were pregnant in the control group 1, and 30 patients were pregnant in the control group 2. The differences in the sperm density, grade a sperm motility rate, and grade (a + b) sperm motility rate, and grade (a + b + c) sperm motility rate between before and after treatment were significantly higher in the treatment group than in the control group 1 and the control group 2 (P < 0.01). The difference in the normal sperm morphology rate between before and after treatment was obviously higher in the treatment group and the control group 1 than in the control group 2 (P < 0.01). Better results were obtained in the treatment group and the control group 1 in improving the sexual apathy, soreness and weakness of waist and knees, impotence, premature ejaculation, seminal emission, dizziness, tinnitus, forgetfulness, alopecia, when compared with the control group 2 (P < 0.01, P < 0.05). There was no statistical difference in the total effective rate of improving Chinese medical symptoms between the treatment group and the control group 1 (P > 0.05).</p><p><b>CONCLUSION</b>BYD combined with TT, LC, and VESC could significantly improve sperm qualities and clinical Chinese medical symptoms of oligospermia patients of SEDS.</p>
