Objective To investigate the clinical effect and quality of life of clopidogrel combined with atorvastatin in the treatment of cerebral infrction.Methods 74 patients with cerebral infarction were randomly divided into study group and control group, 37 cases in each group.The control group applied the traditional treatment methods, and the study group were treated with drug combination therapy ( clopidogrel +fluvastatin) on the basis of the control group.After 1 course (6 months), the scores of neurological function and activity, clinical efficacy and quality of life of the two groups were observed and compared.Results National Institutes of Health Stroke Scale ( NIHSS) and Fugl-Meyer were significantly improved in the two groups at discharge (P<0.05), but the improvement degree of the study group was significantly better than the control group (P<0.05).In the control group, 7 cases were ineffective, the effective rate was 81.1%, while the study group was 3 cases, the effective rate was 91.9%, with statistically significant differences(P<0.05), The study group were significantly better than the control group (P<0.05) in the physiological, environmental, health status and quality of life, but the difference was not statistically significant in the psychological and social dimensions.Conclusion Clopidogrel combined with fluvastatin in treating cerebral infarction could significantly improve the treatment efficiency, effectively control blood lipid levels of patients, and improve nerve function and activity ability of patients, and ultimately improve the quality of life of patients.

Objective To report clinical symptoms of a Chinese pedigree of familial paramyotonia congenital (PMC) with progressive myopathy (PM), and investigate the mutations of hot spots in the adult skeletal muscle sodium channel α-subunit (SCN4A). Methods The medical history and clinical phenotype of the patients from this large family with PMC were collected. Insertional and spontaneous activity were recorded by routine electromyograph (EMG), and the exercise test (ET) and cool water test were also performed on some patients during episodes. The mutations of SCN4A were screened by PCR-SSCP and DNA sequencing in affected and unaffected members. Results The family is a four-generation kindred with 15 members affected by severe, homogeneous paralysis periodiea paramyotoniea pheuotype. The onset was early, and almost all patients developed severe progressive myopathy by middle age. Routine EMG shows myotonia discharge in all affected subjects. The compound remarkably motor action potential (CMAP) decreased more than 40% after ET with greater decreases in cool water test than in ET. The mutation screening study revealed a missense mutation (Met1592Val) in SCN4A in patients. Conclusions Autosomal dominant inheritance pattern with complete penetrance was observed in this family. The phenotype is in accord with that reported in other ethnic populations with more severe symptoms. The ET and cool water tests may be used as an easy and reliable diagnostic method. Our research supports that periodic paralysis and paramyotonia can be caused by the same mutation in SCN4A. Mutation Met1592Val is a hotspot for mutation screening in patients with PMC accompanied by PM in the Chinese population.

Objective To study the clinical efficacy of intra-arterial thrombolysis with recombinant tissue plasminogen activator (rt-PA) for the treatment of ischemic cerebrovascular disease caused by cerebral thrombosis. Methods A total of 245 patients accepted by our hospital during May 2013 and July 2015 were divided into the observation group (n=148) and the control group (n=97). All patients were given conventional process for controling blood pressure and blood lipids. Patients in observation group received intra-arterial thrombolysis with rt-PA, while patients in control group accepted conventional treatment. At the time of admission, the demographic characteristic, vascular influencing factors, baseline clinical findings, laboratory findings and neurological deficits were collected. The improvement of neurological function was evaluated by the modified Rankin scale 3 months after treatment. The levels of fibrinogen (FIB), D-Dimer, activated partial thromboplastin time (APTT) and thrombin time (PT) were measured before and 24 h after the treatment. Results There were no significant differences in demographic characteristic and general clinical data between the two groups ( P>0.05). The proportion of patients with improved neurological function was significantly higher in observation group than that of the control group (83.11％vs. 53.61％, P<0.05). There were no significant difference in coagulation index and fibrinolysis index before treatment between the two groups (P>0.05). Twenty-four hours after the treatment, the levels of FIB, D-Dimer, APTT and PT were significantly improved in the observation group compared with those before treatment. The level of FIB was significantly decreased, D-Dimer was significantly increased, APTT and PT were significantly prolonged in observation group compared with those of control group (P<0.05). Conclusion The rt-PA can effectively dissolve thrombosis and correct the coagulation system and fibrinolytic system.

Objective To evaluate the cumulative irritative effect of topical retinoic acid preparations on normal skin.Methods A randomlized,doubled blind,placebo-controlled clinical trial was carried out with7groups for6tested preparations.All subjects were patch tested with each preparation for24hours on Monday to Thursday,and for72hours on Friday.The patch tests were performed for3consecutive weeks.Results The minimal cumulative irritative effects were found in Group G treated with0.1%adapalene gel,with a cumulative irritative index of0.09?0.11in20days.The cumulative irritative index was significantly lower in Group G than that in Group B treated with0.1%retinoic acid(Diweishuang誖)(0.59?0.24),or in0.025%retinoic acid(Diweishuang誖)(0.41?0.22),or in0.05%retinoic acid(VITAMIN誖Cream)(0.25?0.22).Conclusion Adapalene,the third generation of retinoic acid,is characterized by lower irritative ef-fects in comparison to the first generation of topical retinoic acid agents.

An 81-year-old male presented with an 8-year history of recurrent ulcer on the left dorsal foot which gradually spread to involve both lower limbs. Physical examination revealed no abnormality of any organ systems and no palpable superficial lymph nodes. Skin examination showed erythematous swelling of the left dorsal foot with an ulcer sized 7 cm × 10 cm on the surface. Tendon was visible at the base of the ulcer, and the ulcer margin was elevated giving a dyke-like appearance. The perilesional skin was purple-brown. There were several millet-like papuloid lesions circularly arranged at the inner side of the right foot as well as dark erythematous or brown nodules and pigmented patches with tenderness on both lower limbs. Histopathology of the ulcer of the left dorsal foot and papuloid lesions on the right foot revealed a visible epidermotropic infiltrate in the epidermis as well as an infiltration throughout the entire dermis with medium-sized atypical lymphoid cells with obvious mitoses. Immunohistochemical examination showed the coexpression of both T cell markers (including CD3, CD45RO, CD43) and B cell marker (CD20), with scatted positive staining for PAX-5and negative staining for CD79α or CD1 9. PCR confirmed the rearrangement of T cell receptor (TCR)-γgene. A diagnosis of peripheral T cell lymphoma unspecified was made in view of the rearrangement of TCR-γgene and above findings. The patient was treated with the following modified CHOP regimen: intravenous cyclophosphamide 0.8 g, leurocristine 2 mg and epirubicin hydrochloride 60 mg, as well as oral prednisone 15 mg twice daily for 5 days every 3 weeks (one treatment session). After 3 treatment sessions, the lesions improved markedly.

A 37-year-old female was admitted to the hospital for an itching and painful subcutaneous nodule with ulceration on the extensor aspect of her left forearm for more than 6 months.The pain was severe,continuous and localized.Systemic and local treatment with antibiotics resulted in no obvious improvement.The lesion had gradually increased in size over the past 6 months and the ulcer had enlarged for 1 month.On examination,a hard infiltrative plaque measuring about 5.5 cm × 4.0 cm with a well-defined margin was seen on the extensor aspect of her left forearm,along with ulceration and some dirty discharge on the surface.The diagnosis of fibrosarcoma,grade Ⅱ was eventually made by a biopsy of the lesion,which revealed increased pigmentation in the basal layer,and tumor tissue was tightly adherent to the epidermis.Dermis and subcutaneous fat layer were infiltrated with various sizes of spindle cells with fine collagen fiber bundles between the cells.Obvious atypia and mitotic figures were easily observed in some of the cells.Immunohistochemical analysis showed moderately positive staining for fibronectin,but negative staining for human melanoma black-45 (HMB45),S100,smooth muscle actin (SMA),Melan-a,high molecular weight cytokeratin (HCK),CD34,CD68 or cytokeratin.Some diseases should be differentiated from this case,including dermatofibrosarcoma protuberans,cutaneous spindle cell squamous carcinoma,atypical fibroxanthoma,malignant fibrous histiocytoma,and so on.

Objective:To understand the relationship between the disease condition of patients with coal-burning-borne endemic arsenic poisoning (abbreviated as coal-burning-borne arsenic poisoning) and serum lipid metabolism indicators.Methods:Using a case-control study method, in the coal-burning-borne arsenic poisoning village of Yuzhang Town, Qianxinan Prefecture, Guizhou Province, 204 patients with arsenic poisoning diagnosed according to the standard of "Diagnosis of Endemic Arsenicosis" (WS/T 211-2015) were included in case group, including 87 males and 117 females, aged(53.37 ± 8.06) years old; and they were divided into mild arsenic poisoning group (71 cases), moderate arsenic poisoning group (59 cases) and severe arsenic poisoning group (74 cases) according to the clinical grading. Another 63 residents were selected into control group in a non-arsenic-exposed village about 12 km away from the diseased village, including 23 males and 40 females, aged (53.78 ± 9.10) years old. A face-to-face questionnaire survey was conducted for each group of people, including basic information such as general demographic characteristics, smoking status, and drinking status; fasting peripheral blood was collected, and an automatic biochemical analyzer was used to detect serum total cholesterol (TC) and triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels.Results:There were significant differences of serum TC [(4.94 ± 1.00), (5.00 ± 0.99), (5.27 ± 0.94), (5.57 ± 1.07) mmol/L], TG [(2.17 ± 0.90), (2.25 ± 1.31), (2.66 ± 1.43), (2.78 ± 1.40) mmol/L], LDL-C [(2.51 ± 0.79), (2.74 ± 0.64), (2.97 ± 0.66), (3.15 ± 0.80) mmol/L], and HDL-C levels [(1.57 ± 0.55), (1.42 ± 0.43), (1.36 ± 0.42), (1.30 ± 0.38) mmol/L] in control group, mild, moderate and severe arsenic poisoning groups ( F = 5.83, 3.64, 9.72, 4.41, P < 0.01 or < 0.05). Among them, the serum TC level in severe arsenic poisoning group, serum TG and LDL-C levels in moderate and severe arsenic poisoning groups were significantly higher than those in control group ( P < 0.05); the serum HDL-C level in moderate and severe arsenic poisoning groups were lower than that in control group ( P < 0.05); the serum TC, TG and LDL-C levels in severe arsenic poisoning group were significantly higher than those in mild arsenic poisoning group ( P < 0.05). After linear trend test, serum TC, TG and LDL-C levels all showed an upward trend with the degree of arsenic poisoning ( Ftrend = 15.77, 10.14, 29.15, P < 0.05), and serum HDL-C level showed a downward trend with the degree of arsenic poisoning ( Ftrend = 12.75, P < 0.05). There were significant differences in the abnormal rates of serum TC, TG and LDL-C levels among control group and mild, moderate and severe arsenic poisoning groups (χ 2 = 21.16, 16.60, 8.29, P < 0.01 or < 0.05). Among them, the serum TC and TG levels abnormal rates in moderate and severe arsenic poisoning groups and serum LDL-C level abnormal rate in severe arsenic poisoning group were higher than those in control group ( P < 0.05), the serum TC, TG and LDL-C levels abnormal rates in severe arsenic poisoning group were higher than those in mild arsenic poisoning group ( P < 0.05). There was no significant difference of the serum HDL-C level abnormal rate among four groups (χ 2 = 2.11 , P > 0.05). The results of trend chisquare analysis showed that the abnormal rates of serum TC, TG and LDL-C levels presented an increasing trend with the degree of arsenic poisoning (χ 2trend = 19.90, 15.25, 7.63, P<0.05). The results of logistic regression analysis showed that the risk of abnormal serum TC level in patients with severe arsenic poisoning was 2.90 times that in control group [odds ratio ( OR) = 2.90, 95% confidence interval ( CI): 1.43 - 5.91], and the risk of abnormal serum LDL-C level in patients with severe arsenic poisoning was 2.87 times that in control group ( OR = 2.87, 95% CI: 1.22 - 6.71). Conclusion:There is a correlation between the disease condition of patients with coal-burning-borne arsenic poisoning and their dyslipidemia.

Objective To investigate the differential expression levels and significance of regulatory T cell (Treg) and T helper 17 (Th17) related immunologic factors in peripheral blood of arsenic-exposed rats.Methods Thirty-two Wistar rats were numbered by weight,randomly divided into four groups [control,low (1.25 ml/kg),medium (2.50 ml/kg),and high (5.00 ml/kg)],8 rats per group.Rats in control group were given oral gavage of deionized water,and low,medium and high arsenic exposed groups were given oral gavage doses of 2.00 g/L sodium arsenite (NaAsO2) according to their body weight for 6 days every week.After 4 months,the urine and peripheral blood samples of rats were collected,urinary arsenic (uAs) was detected by inductively coupled plasma-mass spectrometry (ICP-MS),the results were shown in [median (minimum and maximum)],uAs was corrected by urinary creatinine (uCr),the unit was μg/g Cr;enzyme-linked immune-sorbent assay (ELISA) was applied to detect the levels of Treg,Th17,T lymphocytes activation related immunologic factors [interleukin-10 (IL-10),transforming growth factor beta1 (TGF-31),IL-17,IL-6,IL-2],the results were shown in (x) ± s.Results The uAs of the rats was compared between control,low,medium,and high arsenic exposed groups [7.50 (3.16-9.81),72.34 (62.34-106.63),209.15 (154.41-232.20),369.73 (289.50-516.55) μg/g Cr],the differences were statistically significant (F =337.55,P ＜ 0.05).IL-10 [(85.03 ± 7.11),(93.96 ± 8.14),(97.48 ± 6.23),(93.47 ± 4.41) ng/L],TGF-β1 [(72.88 ± 2.96),(81.45 ± 8.15),(86.08 ± 7.55),(90.29 ± 5.35) ng/L],IL-17 [(18.15 ± 3.66),(25.54 ± 5.59),(31.48 ± 5.74),(37.25 ± 7.36) ng/L],IL-6 [(83.68 ± 8.48),(85.14 ± 7.11),(89.78 ± 5.36),(93.48 ± 5.77) ng/L],and IL-2 [(80.65 ± 6.90),(73.86 ± 8.00),(69.93 ± 7.77),(62.06 ± 9.82) ng/L] of the rats were compared between control,low,medium,and high arsenic exposed groups,the differences were statistically significant (F =5.094,11.054,16.249,3.474,5.119,all P ＜ 0.05).There were positive correlations between uAs and TGF-β1,IL-17 concentration (r =0.723,0.605,all P ＜ 0.01),while IL-2 showed a negative correlation (r =-0.484,P ＜ 0.05).Concltsion Arsenic exposure could affect the secretion of Treg and Th17 related immunologic factors,so as to the imbalance of anti-inflammatory and pro-inflammatory,which may play a role in the formation and development of arsenic-related immune injury.
