Objective To improve the diagnosis and treatment of adrenal myelolipoma. Methods Accord-ing to the clinical characteristics and follow-up outcomes,Adrenal myelolipoma 15 patients confirmed by operation and pathology were retrospectively analysed. Of the 15 patients, 11 presented with abdominal or flank pain, of which 3 presented with hypertention,4 presented no symptom. The diagnosis could be made with the aid of ultrasonography,CT and MRI. Results 15 patients underwent surgery, postoperative followed up from 6 months to 7 years, no reccurrence ever noted. Conclusions The diagnosis of adrenal myelolipoma could he established hased on B-US,CT or MRI. The final diagnosis depends on pathology. The operation should be performed as soon as possible if the symptom is severe or the size of tumor is lager than 3.5cm in diameter.

Objective:To investigate the correlation between serum PCT and CRP levels and clinical outcome in patients with acute brucellosis.Methods:From June 2014 to June 2020, 73 patients with acute brucellosis diagnosed in Anji County People's Hospital, Huzhou City were selected as acute brucellosis group and 68 patients with chronic brucellosis as chronic brucellosis group; another 60 healthy people were selected as control group. The levels of serum PCT and CRP of each group were measured by chemiluminescence assay and immunoturbidimetric assay. Patients with acute brucellosis were treated with rifampicin, doxycycline and rifapentine capsules for 9 weeks. The levels of serum PCT and CRP in three groups and patients with acute brucellosis with different therapeutic effects were compared. Univariate and multivariate Cox regression analysis were used to analyze the related factors affecting the efficacy of patients with acute brucellosis. The area under curve (AUC) and cut-off value of receiver operating characteristic (ROC) curve of PCT and CRP were used to evaluate the diagnosis of acute brucellosis.Results:The levels of serum PCT and CRP in acute brucellosis group [(3.25±0.49) ng/ml, (31.28±6.56) mg/L] were higher than those in chronic brucellosis group [(0.12±0.05) ng/ml, (5.21±0.89) mg/L] and control group [(0.03±0.01) ng/ml, (2.63±0.37) mg/L], and those in chronic brucellosis group were higher than those in control group ( P < 0.05). In acute brucellosis patients, 56 cases were effective and 17 cases were ineffective. The levels of serum PCT and CRP in ineffective patients were higher than those in effective patients ( P < 0.05). Univariate Cox regression analysis showed that there were significant differences in leukocyte count, neutrophil count, PCT and CRP levels among acute brucellosis patients with different therapeutic effects ( P < 0.05). Multivariate Cox regression analysis showed that leukocyte count, neutrophil count, PCT and CRP levels were the risk factors for therapeutic effect ( P < 0.05). The diagnostic evaluation showed that the sensitivity and specificity of PCT in the diagnosis of acute brucellosis were 95.24% and 80.00%, respectively; and the sensitivity and specificity of CRP in the diagnosis of acute brucellosis were 93.10% and 80.00%, respectively. Conclusion:The levels of serum PCT and CRP in patients with acute brucellosis are significantly increased, and they are risk factors for therapeutic effect, which should be used as reference indexes for diagnosis and treatment of acute brucellosis.

Objective To investigate the effects of three-dimensional titanium mesh repair on cerebral perfusion,intracranial pressure and nerve function after decompression with bone flap.Methods From October 2015 to October 2018,132 hypertensive cerebral hemorrhage patients of bone disc decompression in the Fifth People's Hospital of Jinan were selected and divided into observation group (66 cases) and control group(66 cases) by double blind random method.The observation group received three-dimensional titanium mesh repair at 24 ～ 42 d after bone disc decompression surgery.The control group received three-dimensional titanium mesh repair at 90 ～ 150 d(3 ～ 5 months) after surgery.The changes of operation,cerebral perfusion,intracranial pressure and nerve function were compared between the two groups.Results The operative time,blood loss and free time of the flap in the observation group were (92.5 ± 12.4) min,(354.3 ± 17.5) mL and (13.2 ± 3.1) min,respectively,which were shorter or less than those in the control group [(142.8 ± 15.3) min,(518.3 ± 22.3) mL and (38.3 ± 4.3) min],the differences between the two groups were statistically significant (t=4.745,6.831,4.963,all P ＜ 0.05).After treatment,the abnormal indices of intracranial pressure and cerebral perfusion in the observation group were (0.1 ±0.0) and(0.2 ± 0.1),respectively,which were lower than those in the control group [(0.2 ± 0.1),(0.3 ± 0.1)] (t =3.657,2.579,all P ＜0.05).There were statistically significant differences in neurological deficit scores between the two groups at different time points(all P ＜0.05).The incidence of treatment complications in the observation group was 10.94％ (7/64),which was significantly lower than that in the control group [38.7％ (24/62)] (x2 =14.094,P ＜ 0.05).Conclusion Three-dimensional titanium mesh repair is helpful to shorten the operation time,restore the intracranial pressure on the affected side,improve the abnormal cerebral perfusion,and reduce the neurological damage in patients with hypertensive cerebral hemorrhage.

OBJECTIVE：To establish the HP LC fing erprints of Oxalis corniculata and to simultaneously determine the contents of isovitexin and swertisin. METHODS ：HPLC method was adopted. The determination was performed on ACE Excel- 5-C18column with mobile phase consisted of methanol- 0.1％ phosphoric acid water （gradient elution ）at the flow rate of 1 mL/min. The column temperature was 35 ℃，and detection wavelength was set at 280 nm. The sample size was 10 μL. Using isovitexin peak as reference，HPLC fingerprints of 12 batches of sample were drawn. The similarity evaluation was performed by using Similarity Evaluation System of Chromatogram Fingerprint of TCM （2012 edition）to determine common peaks. The contents of isovitexin and swertisin were determined by same method of above chromatogram. RESULTS ：There were 19 common peaks in HPLC chromatogram of 12 batches of O. corniculata ，with the similarity above 0.89. Two common peaks including isovitexin and swertisin were identified. The linear range of two components were 3.91-117.36 μg/mL（r＝0.999 4）and 9.88-118.56 μg/mL（r＝ 0.999 2），respectively. The limits of quantitation were 0.675 and 3.587 μg/mL；the limits of detection were 0.205 and 1.087 μg/mL， respectively. RSDs of precision ，stability and reproducibility tests were all lower than 2％. The recoveries were 95.46％-99.10％ （RSD＝1.23％ ，n＝6），95.34％ -101.23％（RSD＝2.74％ ，n＝6），respectively. The average contents were 0.227-1.654， 0.641-2.052 mg/g，respectively. CONCLUSIONS ：Established fingerprints can be used for the quality control of O. corniculata ； the content determination method is simple and accu rate，and can be used for simultaneous determination of two components.
