Objective To investigate the diagnostic value of serum amyloid A(SAA)in diagnosing acute exacerbations of chronic obstructive pulmonary disease(AECOPD).Methods A total of 86 patients with AECOPD and 46 patients with stable COPD were recruited.SAA determined with ELISA was compared between AECOPD patients and stable COPD patients.The changes of SAA,WBC,the percentage of neutrophils and C-reactive protein (CRP) of AECOPD patients Was compared before and immediately after the last treatment procedure.Results The SAA levels in AECOPD patients were higher than those in stable COPD patients [(182.33±50.12)mg/L vs (6.24±3.05)mg/L,P<0.05].The change of SAA was more evident than that of serum WBC and the percentage of neutrophils before and after the treatment procedure. SAA was more sensitive than CRP in diagnosing lung function severity of AECOPD patients.Conclusion SAA has great diagnostic value in AECOPD diagnosis and evaluation of lung function severity.

Thyroid hormone insensitive syndrome is an inherited disease characterized by decreased target tissue responsiveness to thyroid hormone. Most cases are due to thyroid hormone receptor β gene mutation. Two novel types of thyroid hormone insensitive syndrome were recently identified, which are caused by gene mutations of MCT8, a specific thyroid hormone transporter, and SBP2 in the synthesis of deiodinase.

BACKGROUND: Anterior cruciate ligament (ACL) is the kernel of articular genu, for the past few years, the incidence rate of cruciate ligament injury increased gradually.OBJECTIVE: To review on the mechanism of the injury of ACL, the method of operation, the election of transplant, the reconstruction of equilong, the reconstruction of ligament and so on, and to look forward to providing some references on treating the ACL injury.METHODS: A computer-based research was conducted in Medine database (1996-01/2009-03), with the key words of "Anterior cruciate ligament, implant, reconstruction, repair". Chongqing VIP database and Qinghua Tongfang database (1996-01/2009-03) were retrieved with the same key words.RESULTS AND CONCLUSIONS: 200 literatures on arthroscopic ACL reconstruction were collected, excluding older, repeated and similar research, and the 18 standard literatures were included. ACL is a key structure to stabilize knee joint, and exercises and various factors during daily life could induce its injury. Unsuitable treatment would severely affect movement ability or movement loss. To recover structure and function of knee joint, damaged ACL should be reconstructed. With the development of technique and innovation of surgical instrument, arthroscopic reconstruction has presently been a popular method to treat ACL. There are many methods to treat ACL injury, but none of them can duplicate ACL anatomical relationship. It is still in doubt whether the operation can reduce the secondary damage. We have much more work to research on modus operandi, implant, postoperative rehabilitation and other adjunctive therapies.

Objective To analyze the clinical efficacy of trimetazidine in short-term treatment for dilated cardiomyopathy accompanied by heart failure. Methods Sixty seven cases of dilated cardiomyopathy patients with heart failure were recruited and divided into two groups randomly,the control group(n = 33) had conventional therapy and the treatment group (n = 34) had conventional therapy plus oral tid 20 mg trimetazidine administration for 3 months. Results The heart function improved significantly in both groups. The overall effective rate was significantly lower in the control group than the treatment group(69. 7% vs. 88.2%,P ＜ 0. 05). In the treatment group, before treating the left ventricular ejection fraction(LVEF), stroke volume (SV), cardiac output per minute (CO), 6 min walk test(6-MWT), were(28.7 ± 13. 6) %,(31.0 ± 8. 7) ml,(3. 10 ± 0. 49) L/min,(138.0 ± 30. 4) m respectively, and after treazing these indices were(38. 5 ± 9. 7) %,(48. 5 ± 6. 8) ml, (4. 90 ± 0. 98) L/min,(350. 0 ± 20. 4) m respectively, which increased significantly after treatment(Ps ＜0. 05). However,in the treatment group ,before treatment left ventricular. End-systolic dimension (LVESD), left ventricular end-diastolic dimension (LVEDD) and brain natriuretic peptide (BNP) were (68. 0 ± 8. 0)mm,(70. 0 ± 7. 8) mm,(669. 0 ± 71.4) μg/L respectively, whereas after treatment these indices were(59. 0 ± 6. 7) mm,(68.0 ± 7. 9) μg/L,(340. 0 ± 56. 0) μg/L respectively, which decreased significantly after treatment(Ps ＜ 0. 05). In the control group, before treatment LVEF, SV, CO, 6-M WT were(28. 5 ±13.9) %,(30. 0 ± 9. 9) ml,(3.00 ± 0. 48) L/min,(130. 0 ± 28. 6) m respectively, whereas after treating these indices were(34. 0 ± 8. 5) %,(34. 0±11.0) ml,(3. 90 ± 0. 56) L/min,(254. 0 ± 30. 0) m, respectively,which increased significantly after treatment(Ps ＜ 0. 05). While in the control group, before treatment LVESD,LVEDD and BNP were (67.0 ± 9. 0) mm, (70. 0 ± 8.0) mm,(666. 0 ± 70. 8) μg/L respectively, whereas after treatment these indices were(60. 0 ± 5. 5) mm,(66. 0 ± 5.7) mm,(350. 0 ± 55.3) μg/L respectively, which decreased significantly after treatment (Ps ＜ 0. 05). Moreever, the improvement of these indices in the treatment group were significantly higher than those in the control group (Ps ＜ 0. 05). Conclusion The additional administration of trimetazidine to conventional anti-failure treatment can significantly improve the heart function in patients with dilated cardiomyopathy,which is worth to be generalized clinically.

Objective Inaccurate dosing is an important cause of medical malpractice, how to adjust the medication dose to overcome the excessive deviation will be discussed in this paper. Methods Gold zone method was proposed on the basis of the probability theory and mathematical statistics for handling inaccurate dosing problems. Investigation and study in large sample size was carried out on adverse reactions of Cefamandole Nafate for Injection by adopting the method. Results The conclusions from the super large sample size test indicate that there is highly significant difference of total adverse reaction rates between taking values within and outside golden zone of dosage, and the adverse reaction rate of taking values within golden zone is significantly lower than that of outside golden zone. It is noteworthy that when dosage was lower than golden zone,the adverse reaction rate was significantly increased,which is more than 4 times of that within golden zone. Conclusion It is effective measures and simply and easy to apply that taking values within golden zone of dosage reduce adverse drug reactions,probability within golden zone less than 1/4 range of experience that contains the actual demand of the body up to 70%.

To study the influences of the demographic evolution to government expenditure on health by using the method of generalized method of moment(GMM)by dynamic panel data of 31 provinces or cities from 1998 to 2011. The result showed that the elderly dependency ratio had a significant positive impact on government health expenditure, while the reduction of child dependency ratio would increase it. There were clear differences among regions. The elderly and child dependency ratio were both significantly positive for the eastern region, no significant effect for the central, and positive and negative respectively for the western. Therefore, it is needed to further improve the proportion of government health spending in total health expenditure, increase transfer payment, reduce regional differences and achieve the equalization of basic public health services.
