OBJECTIVE:To observe the clinical efficacy and safety of different doses of atorvastatin in the treatment of chron-ic subdural hematoma(CSDH). METHODS:One hundred and tweaty-eighie CSDH patients selected from our hospital during Jun. 2013-May 2015 were divided into observation group(n=62)and control group(n=66)in accordance with random number table. Both groups were given conventional treatment of brain cell nutrition. Control group received Atorvastatin tablet 20 mg,po,qd;observation group received Atorvastatin tablet 40 mg,po,qd. Both groups were treated for 6 months. Clinical efficacy,CSS and ADL score,hematoma volume,the levels of serum inflammatory factors (hs-CRP,MMP-9,IL-6,TNF-α) were observed in 2 groups. ADR was recorded during treatment and recurrence rate was also recorded. RESULTS:2 patients withdrew from observa-tion group and 6 from control group. Finally,120 patients met the criteria were included,with 60 cases in each group. Total re-sponse rate of observation group(88.3%)was significantly better than that of control group(73.3%),with statistical significance (P<0.05). After 1,3,6 months of treatment,CSS score,hematoma volume,the serum levels of hs-CRP,MMP-9,IL-6 and TNF-α in 2 groups were significantly decreased,while ADL score was increased significantly;the improvement of above indexes in observation group was significantly better than in control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). The recurrence rate of control group(13.3%)was significantly higher than that of observation group(3.3%),with statistical significance(P<0.05). CONCLUSIONS:Daily dose of shows ator-vastatin 40 mg better therapeutic efficacy and lower recurrence rate in the treatment of CSDH with good safety.

OBJECTIVE: To discuss the clinical features, diagnosis and endoscopic surgical intervention for small steoma of nasal sinuses causing nasal and facial pain. METHOD: A retrospective review was performed on 21 patients with nasal and facial pain caused by small osteoma of nasal sinuses, and nasal endoscopic surgery was included in the treatment of all cases. RESULT: The nasal and facial pain of all the patients was relieved. Except for one ase exhibiting periorbital bruise after operation, the other patients showed no postoperative complications. CONCLUSION Nasal and facial pain caused by small osteoma of nasal sinuses was clinically rare, mostly due to the neuropathic pain of nose and face caused by local compression resulting from the expansion of osteoma. Early diagnosis and operative treatment can significantly relieve nasal and facial pain.

Objective:To observe the protein and mRNA expressions of microtubule-associated protein 1 light chain 3 (LC3)B, P62 and Beclin1 in the liver of rats with chronic fluorosis, and to explore the role of autophagy in pathogenesis of liver injury induced by fluorosis.Methods:Using a group design, 54 SD rats were divided into 9 groups according to their weight (100 - 120 g) using a random number table method, each group with 6 rats, half male and half female. They were control group (NC group), low fluoride group (LF group), high fluoride group (HF group), NC + rapamycin (RAP) group, LF + RAP group, HF + RAP group, NC + chloroquine (CQ) group, LF + CQ group, and HF + CQ group. The NC group drank tap water (fluoride concentration was 0.5 mg/L), LF group drank fluoride water (fluoride concentration was 5.0 mg/L), HF group drank fluoride water (fluoride concentration was 50.0 mg/L); NC + RAP group, LF + RAP group and HF + RAP group were fed with corresponding drinking water, respectively, for 3 months, and then RAP (1.5 mg/kg) was intraperitoneally administered for 10 d; NC + CQ group, LF + CQ group and HF + CQ group were fed with corresponding drinking water, respectively, for 3 months, and then CQ (60 mg/kg) was intraperitoneally administered for 10 d. Bone and 24-hour urine samples of rats in each group were collected to detect the contents of bone fluoride and urine fluoride; liver histomorphological changes were observed through hematoxylineosin staining; protein and mRNA expressions of LC3B, P62 and Beclin1 in liver were detected by immunohistochemistry and real-time fluorescence quantitative PCR, respectively.Results:Compared with the NC group [(0.03 ± 0.00) mg/kg, (0.34 ± 0.08) mg/L], the contents of bone fluoride [(3.86 ± 0.08) mg/kg] and urine fluoride [(1.11 ± 0.16) mg/L] in HF group were higher ( P < 0.05). In the NC group, the lobule structure of liver tissue was clear, the hepatic cords were arranged in order, and the cell structure was normal. There were different degrees of hepatocyte edema in LF and HF groups. After intraperitoneal injection of RAP, compared with the corresponding fluoride group, the morphology of hepatocytes did not change significantly. After intraperitoneal injection of CQ, compared with the corresponding fluoride group, the liver cells showed obvious edema, and the degree of edema aggravated with the increase of fluoride concentration. Compared with the NC group, the protein expressions of LC3B and Beclin1 in HF group were higher ( P < 0.05), and the protein expression of P62 was lower ( P < 0.05). After intraperitoneal injection of RAP, the protein expressions of LC3B and P62 in LF + RAP group was lower than that in LF group ( P < 0.05); Compared with HF group, the protein expressions of LC3B and Beclin1 in HF + RAP group were lower ( P < 0.05). After intraperitoneal injection of CQ, protein expression of P62 in LF + CQ group was higher than that in LF group ( P < 0.05); Compared with HF group, protein expression of P62 in HF + CQ group was higher ( P < 0.05). Conclusions:Early (3 month) fluoride intake could promote autophagy and induce edema of hepatocytes in rats, and RAP had similar effects. CQ may induce liver injury by inhibiting autophagy of hepatocytes.

OBJECTIVETo explore the effect of Danshensu on the lipid metabolism of hyperlipidemic rats.

METHODSixty clean male SD rats were selected. Twelve of them were selected in the basic control group and fed with common foods, and the remaining rats were fed with the high-fat feeds. After the successful modeling, they were randomly divided into the high-fat control group and low dose (10 mg x kg(-1) x d(-1)), medium dose (20 mg x kg(-1) x d(-1)) and high dose (40 mg x kg(-1) x d(-1)) Danshensu (dissolved in saline) groups. Both of the two groups were abdominally injected with the same volume of normal saline once a day for consecutively 30 days. The serum TG, TC, HDL-C and liver ACC1, FAS, HMGR, CPT-I mRNA expressions were detected.

RESULT AND CONCLUSIONDanshensu could inhibit the LDL-C level, timely clear redundant cholesterol and effectively regulate the lipid metablism of hyperlipidemic rats by reducing the TC content, decrease the fatty acid by reducing the FAS mRNA expression, and reduce the synthesis levels of endogenous cholesterol by inhibit the HMGR mRNA expression.

Objective To analyze the ultrasonic features of thyroid microcarcinoma (TMC) and the causes of misdiagnosis. Methods The ultrasonic features including shape, margin, echogenecity, microcalcification, vascularity and lymphadenopathy were analyzed retrospectively in 26 pathologically-proven TMC patients. Results In 26 cases, 11 cases were diagnosed correctly before operation (11/26, 42.31%), 12 cases were misdiagnosed (12/26, 46.15%) as adenoma or benign nodule, and 3 cases were missed diagnosed (3/26, 11.54%). Among the 23 cases detected on ultrasound, 21 cases were solid and hypoechoic (21/23, 91.30%);19 cases were ill-defined (19/23, 82.61%);12 cases were taller than wide in shape (12/23, 52.17%); 14 cases had microcalcification (14/23, 60.87%); 7 cases showed central or peripheral blood flow signals (7/23,30.43%) with arterial resistance index>0.70 in 3 lesions and<0.70 in 4 lesions. Conclusions Several ultrasonographic features are helpful in identiifcation of TMC, including hypo/iso-echogenecity, ill-deifned margin, taller-than-wide shape, microcalciifcation, arterial signals with high resistance index, and abnormal lymphadenopathy. Moreover, for cases with multiple lesions, to the potential co-existence of benign and malignant lesions should be considered.

Objective:To observe modulation of gut functions and intestinal mucosal immune barrier by ShengJiangXieXinTang in rats receiving Irinotecan(CPT-11).Methods:Sprague Dawley male rats(n=18)were randomly assigned to three groups:(1)herb group (using ShengJiangXieXinTang by oral administration once a day from day 1 to day 9 and being injected with 150 mg/kg?d CPT-11 on day 4 and 5 into the tail vein); (2)diarrhea control group: using distilled water instead of ShengJiangXieXinTang,with the same treatment of CPT-11 as the herb group; (3)normal control group: using normal saline instead of CPT-11, distilled water instead of ShengJiangXieXinTang,and with the same treatment of as the CPT-11 herb group.The animals were scored in terms of delayed-onset of diarrhea. Rats were killed on day 10,collecting ileum,cecum and colon for pathological examination.The damages in intestinal mucosa were assessed under light microscope according to the criterion of chiu's score.CD4+,CD8+T-lymphocytes and SIgA were enumerated by immunohistochemical staining and calculated by imaging analyzer.Results:Compared with diarrhea control group,the incidence of diarrhea and the damage in intestinal mucosa of the herb group was milder(P

Objective To investigate the diagnosis and treatment characteristics of pure red cell aplasia (PRCA)caused by human parvovirus (HPV)B19 infection after renal transplantation.Methods Two cases with PRCA caused by HPV B19-induced after renal transplantation,who were treated in the Department of Organ Transplantation,Nanfang Hospital,Southern Medical University,were summarized.Combined with literature review,the clinical characteristics,diagnostic method,course of treatment and prognosis of such disease were investigated.Results Two renal transplant recipients developed severe anemia early after transplantation with progressive deterioration and failed transfusion therapy.Other causes of anemia were ruled out and two patients were diagnosed as PRCA caused by HPV B19 infection according to bone marrow aspiration and biopsy as well as HPV DNA detection by fluorescent polymerase chain reaction (PCR).The symptoms of anemia were improved significantly after adjustment of immunosuppressive treatment protocol and intravenous immunoglobulin (IVIG).Conclusions For patients with unexplained and progressed anemia early after renal transplantation,especially those complicated with reticulocyte deficiency,the possibility of PRCA caused by HPV B19 infection shall be considered.The results of bone marrow aspiration and fluorescent PCR are the main bases for diagnosing PRCA.Immunosuppressive agents reduction and application of IVIG are the major treatment measures.Most of patients have great prognosis after treatment,but this disease is likely to recur.
