BACKGROUND:Ilizarov bone transport is very effective in the treatment of open large tibial bone defects,but there are still complications,among which the difficulty of junction healing is one of the difficult points in treatment. OBJECTIVE:To investigate the effect of Ilizarov bone transport combined with antibiotic bone cement on junction healing after operation of open large tibial bone defect. METHODS:Totally 51 patients with open large tibial bone defect(bone defect>4 cm)admitted to Binzhou Medical University Hospital from August 2010 to January 2022 were selected,of which 28 received Ilizarov bone transport alone(control group)and 23 received Ilizarov bone transport combined with antibiotic bone cement treatment(trial group).External fixation time,bone healing time,bone healing index,visual analog scale score during bone removal,bone defect limb function,junction healing and complications at the final follow-up were statistically compared between the two groups. RESULTS AND CONCLUSION:(1)All the 51 patients were followed up for a mean of(22.53±5.77)months.External fixation time,bone healing time,bone healing index,postoperative infection rate,and non-healing rate of junction were less in the trial group than those in the control group(P<0.05).There was no significant difference between the two groups in visual analog scale scores at 6 months after the second surgery and in the functional excellence and good rate of limb with bone defect at the final follow-up(P>0.05).(2)These findings indicate that compared with the Ilizarov bone transport alone,Ilizarov bone transport combined with antibiotic bone cement treatment can promote the healing of open tibial fracture junction and increase the rate of bone healing.

Objective To analyze the medication rules of Professor LAO Shaoxian in the treatment of gastric stuffiness based on syndrome differentiation.Methods The effective prescriptions for patients with gastric stuffiness treated by Professor LAO Shaoxian from March 2017 to March 2022 were collected,and the general information,chief complaints,diagnosis,syndrome differentiation and prescriptions of patients were extracted.Excel software and the ancient and modern medical records cloud platform(V 2.3.7)were used to construct the prescription database.Data mining function was used to carry out analysis of the syndrome type of prescription,analysis of the frequency and property of Chinese herbs,as well as association rule analysis and cluster analysis.Results A total of 272 prescriptions were included,involving 164 kinds of medicinal herbs.The main traditional Chinese medicine(TCM)syndrome types are damp-heat syndrome and qi stagnation syndrome.The frequency of 25 herbs was more than or equal to 30 times.The representative herbs is Pinellinae Rhizoma Praeparatum,Glycyrrhizae Radix et Rhizoma,Citri Reticulatae Pericarpium,Perillae Caulis and Aucklandiae Radix.The medicinal properties are mainly warm and flat.The medicinal flavors are spicy,bitter and sweet.The drug meridians mainly included the spleen,stomach and lung meridians,followed by the liver meridian.There were 23 core drug pairs obtained by association rules,such as"Aucklandiae Radix-Perillae Caulis","Citri Reticulatae Pericarpium-Perillae Caulis",and"Pinellinae Rhizoma Praeparatum-Citri Reticulatae Pericarpium".Clustering analysis of drugs can be divided into three combinations,which have the effects of regulating qi and relieving distension,resolving dampness,and clearing heat and detoxifying.Conclusion The core prescription of Professor LAO Shaoxian in the treatment of gastric stuffiness is Aucklandiae Radix,Perillae Caulis,Citri Reticulatae Pericarpium,Pinellinae Rhizoma Praeparatum,Glycyrrhizae Radix et Rhizoma,Kaki Calyx,Aurantii Fructus Immaturus and Arecae Pericarpium.It focuses on regulating qi movement of middle jiao and treating spleen and stomach simultaneously.The main therapeutic method is regulating qi and relieving distension.At the same time,attention should be paid to the application of dampness-dispelling and stagnation-removing,heat-clearing and detoxifying drugs.The clinical therapy of Professor LAO Shaoxian on gastric stuffiness is significant,which can be used as a reference for diagnosis and treatment.

Objective:To investigate the change and clinical significance of serum alkaline phosphatase (ALP) level in patients with acute spontaneous intracerebral hemorrhage(AICH).Methods:81 patients with AICH admitted to the Neurosurgery Department of Tianjin Third Central Hospital from January 2019 to October 2020 were retrospectively analyzed. 81 patients with non cerebral hemorrhage who came from the health examination center or complained of dizziness and had no hepatobiliary and skeletal diseases were selected as the control group. The clinical data of all the patients were recorded, including gender, age, Glasgow Coma Scale (GCS) score, hemorrhage location, liver function indexes, the history of hypertension, diabetes, heart disease, smoking, drinking, and so on. The differences in clinical data between the two groups were compared. Pearson correlation was used to analyze the correlation between liver function indexes and GCS score. The independent risk factors for AICH were screened by binary logistic regression, and the receiver operating characteristic (ROC) curve was used to evaluate the value of serum ALP in predicting intracerebral hemorrhage.Results:Serum ALP level in AICH group was significantly higher than that in the control group [85.0(70.0, 103.0) U/L vs 65.0(54.5, 71.5)U/L, Z=6.740, P<0.001]. Pearson correlation analysis showed that serum ALP had a negative correlation with GCS score ( r=0.255, P=0.022). Binary logistic regression analysis showed that hypertension ( OR=20.440, 95% CI 8.572-48.737) and ALP ( OR=1.077, 95% CI 1.049-1.105) were risk factors for intracerebral hemorrhage. Serum ALP level was an independent risk factor ( OR=1.069, 95% CI 1.038-1.101) for AICH after adjusting for confounding variables including age, AST, history of hypertension. ROC curve showed that the area under the curve (AUC) of serum ALP in predicting intracerebral hemorrhage was 0.807 (95% CI 0.740-0.873, P<0.001), with sensitivity of 67.9% and specificity of 81.5%. Conclusions:Serum ALP level may be related to the occurrence and severity of AICH. Therefore, serum ALP level can be used as a reference index to evaluate the occurrence, severity of patients with AICH.

Acute promyelocytic leukemia (APL) was considered to be the most rapidly fatal leukemia,because of serve clinical manifestation,high rate of early death and the low cure rate.APL has achieved great success due to the application of ATRA and ATO.Although the complete remission rate is about 90％,the relapse rate has been reported to be as high as 15％-30％.So reducing the recurrence and improving long-time survival have become the focus of the study.Choosing the reasonable treatment after remission is very important.The post remission therapy usually include consolidation therapy and maintenance therapy,but the optimal strategy has been controversy.Therefore,this artical will review the literature of APL in consolidation therapy.

OBJECTIVETo evaluate the efficacy and safety of anagrelide in essential thrombocythemia (ET).

METHODSPatients who diagnosed as ET according to the World Health Organization classification were enrolled. Each patient was assigned to take anagrelide hydrochloride capsule or hydroxyurea tablet by random 1∶1 ratio. Dose of anagrelide started at 2 mg/d, then increased gradually and the maximum dose was 10 mg/d until the platelet counts dropped to (100-400) × 10⁹/L, one month later gradually reduced to maintain dose. The dose of hydroxyurea was 1000 mg/d at beginning, then increased gradually, when platelet counts dropped to (100-400)×10⁹/L and kept for one month, reduced to maintain dose as 10 mg·kg⁻¹·d⁻¹. The observation period was 12 weeks.

RESULTSA total of 222 patients were enrolled in seventeen centers (including 113 patients treated with anagrelide and 109 with hydroxyurea). Therapy efficacy can be evaluated in 198 patients (including 97 patients administered with anagrelide and 101 with hydroxyurea). At 12th weeks of therapy, the hematologic remission rate was 87.63% (85/97) in anagrelide group and 88.12% (89/107) in hydroxyurea group, the differences between the two groups were not significant (P=0.173). Treatment with anagrelide lowered the platelet counts by a median of 393 (362-1 339) × 10⁹/L from a median of 827 (562-1657) × 109/L at the beginning of the observation to 400(127-1130)×10⁹/L after 12 weeks (P<0.001), which were similar to the treatment result of hydroxyurea by a median drop of 398 (597-1846)× 10⁹/L (P=0.982). The median time to achieving response of anagrelide group was 7 (3-14) days, superior to that of hydroxyurea for 21 (14-28) significantly (P=0.003). Frequency of anagrelide related adverse events was 65.49 % (74/113), including cardiopalmus (36.28% ), headache (21.24% ), fatigue (14.16% ) and dizzy (11.50% ).

CONCLUSIONAnagrelide was effective in patients with ET which had similar hematologic remission rate to hydroxyurea and could take effect more quickly than hydroxyurea. Incidence of adverse events was undifferentiated between anagrelide and hydroxyurea, but anagrelide treatment had tolerable adverse effects and no hematologic toxicity.

Objective Pleural effusion of patients with tuberculous pleurisy was analyzed by ultra high performance liquid chromatography-mass spectrometry (UPLC-MS).Orthogonal partial least squares discriminant analysis (OPLS-DA) model was established for searching and analyzing the potential metabolic biomarkers to provide new ideas for the early diagnosis of tuberculosis pleurisy.Methods Totally 166 cases of pleural samples were collected from November 2012 to September 2013 in Tianjin Haihe Hospital (tuberculosis pleurisy 83 cases,bacterial pleurisy 31 cases,lung cancer 30 cases and heart failure 22 cases)and metabonomics quantitative analysis was conducted.Quantitative analysis of metabolic methods was enrolled.Orthogonal partial least squares discriminant analysis (OPLS-DA) model was constructed by the pattern recognition method.Based on the OPLS-DA model,potential biomarkers was filtered preliminary by variable importance in the projection (VIP) and VIP confidence interval value.The specific metabolites were determined by applying non-parametric test(Kruskal-Wallis H test)by using SPSS 17.0,and potential metabolic biomarkers were screened.Results The prediction accuracy of OPLS-DA model was 100％ (38/38),which illustrated that the model could verify the tuberculous pleurisy group and the control group accurately.Based on the data of metabolites,46 potential metabolites were finally screened and 5 metabolites were identified with statistically significant differences (P ＜ 0.05).The data of tuberculosis pleurisy group showed a significant increase in 17a,20a-Dihydroxy cholesteryl,phospholipid [20∶4 (8Z,11Z,14z,17Z)] (1 188 670.00),tocotrienols (1 051 760.00) and phospholipid(O-18:0) (434 394.00) compared with the lung cancer group(735 615.00,336 815.00,324 563.00,193 055.00),bacterial pleurisy group (1 678 805.00,598 256.50,699 384.00,343 866.00),and heart failure group(535 842.00,253 503.00,234 503.00,130 185.00) (H =26.787,18.680,26.193,21.024,P ＜0.01),and a significant decrease in L-phenylalanine(245 976.00)compared with the lung cancer group(753 033.50),bacterial pleurisy group (357 278.00),and heart failure group(586 678.00) (H =13.635,P ＜ 0.01).Conclusions The OPLSDA model constructed on the basic of UPLC-MS technology platform can verify the tuberculous pleurisy group and the control group accurately,and the study provides new ideas and methods for identifying features of tuberculous pleurisy markers and early diagnosis.

Objective To investigate the association of restriction fragment length polymorphisms (RFLP) in p.S267F of SLC10A1 gene with clinical outcomes of hepatitis B virus (HBV) infection. Methods Clinical data of 1 268 patients with HBV infections admitted in Public Health Clinical Center Affiliated to Fudan University during July 2014 and February 2015 were collected.Polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP) method was used to genotype the p .S267F of SLC10A1 gene in all patients, and the potential association between variants in p .S267F of SLC10A1 gene and the clinical outcomes of HBV infection was analyzed .Results Among 1 268 patients with HBV infections, 1 226 were of genotype CC, and 42 were of genotype CT, so the variation rate in p.S267F was 3.31%(42/1 268).Compared with patients with genotype CC , patients with genotype CT had a higher incidence of acute HBV infections (13.6%vs.28.6%,χ2 =19.819, P<0.05) and a lower incidence of HBV-related liver cirrhosis or hepatocellular carcinoma (13.9% vs.4.8%, χ2 =18.945, P <0.05). Conclusion RFLP in p.S267F of SLC10A1 gene may be associated with chronicity and aggravation of HBV infection, and genotype CT is possibly a protective factor .

Objective To explore the diagnostic value of combined detection of the liquid array technology, interfer-on (IFN)-γand IFN-γ-inducible protein (IP)-10 in the rapid, accurate diagnosis and differential diagnosis of tuberculous pleural effusions. Methods Patients with transudative pleural effusions were divided into tuberculous pleural effusion group (n=52) and malignant pleural effusion group (n=38). The method of T-SPOT.TB was used to detect the number of effec-tor T cells sensitized to Mycobacterium tuberculosis and spot forming cells (SFCs). The liquid array technology was used to detect the level of IFN-γand IP-10. Logistic regression was used to analyze and compare the diagnostic value of the two-method combination. Results The diagnostic sensitivity, specificity and the area under the ROC curve (AUC) of T-SPOT. TB were 90.38%, 84.21%, and 0.938 (95%CI:0.867-0.978), respectively. The diagnostic sensitivity, specificity and AUC of combined detection of IFN-γand IP-10 were 98.08%, 97.37%, and 0.995 (95%CI:0.951-1.000), respectively. There was no significant difference in the diagnostic sensitivity and specificity between the two methods, and the diagnostic agreement for the two diagnostic methods was fine (Kappa=0.703). The difference of AUC between the methods was significantly differ-ent (Z=1.996, P<0.05). The method of combined detection of IFN-γand IP-10 showed the larger AUC (AUC=0.995). Con-clusion The combined diagnosis meets the clinical needs of rapid, accurate diagnosis and differential diagnosis for tuber-culous pleural effusion by simultaneously assaying the level of IFN-γand IP-10 using the liquid array technology.
