BACKGROUND: The method of replenishing kidney has becoming one of the therapies for anti-senility in gerontology in Chinese medicine.OBJECTIVE: To probe into the effects of the formula for nourishing kidney yin-zuoguiyin on serum malondialdehyde (MAD) content and superoxide dismutase (SOD) activity in metabolism of free radical.DESIGN: Complete randomized control experiment.SETTINGS: Microbiology and Immunology Department of Guangdong Medical College.PARTICIPANTS: The experiment was performed in Immunology Research Room of Wannan Medical College from September 2002 to July 2004. Forty male senile ICR mice were employed, provided by Institute of Experimental Animal of Medical Scientific Academy in Sichuan. They were randomized into senile control, zuoguiyin group, single shudi (Radix Rehmanniae Praeparata) group (single group) and shudi (Radix Rehmanniae Praeparata) removal group (removal group), 10 mice in each one. Zuoguiyin composes of shudi (Radix Rehmanniae Praeparata), shamyao (Rhizoma Dioscoreae), gouqi (Fructus Lycii), zhi gancao (Radix Glycyrrhizae Praeparata),fuling (Poria) and shangyurou (Fructus Corni) at the ratio of 9:6:6:3:4:5. After decocted routinely, the solution in zuoguiyin group was concentrated to 0.577 5 g/mL of raw herbs contained; that in single group was to 0.157 5 g/mL and that in removal group was to 0.42 g/mL. The mixed medical solutions of 100 g/L were prepared successively in each group.INTERVENTIONS: In zuoguiyin group, single group and removal group,solutions of zuoguiyin and shudi (Radix Rehmanniae Praeparata) and solution with shudi (Radix Rehmanniae Praeparata) removed were administrated successively, 4 times/day, 1.5 mL/time, totally for 75 days. No any drink was provided during the medication. The mice in senile control drank pipe water. After the eyeball extracted, blood of 2 mL collected and serum preserved, the thiobarbituric acid method was used to determine MAD content, the xanthine oxidase method was to determine SOD activity and the colorimetric method was to determine general capacity of anti-oxidation in serum.MAIN OUTCOME MEASURES: ① serum MAD content; ② serum SOD activity; ③ general capacity of anti-oxidation in serum.RESULTS: One mouse was dead in senile control and 3 mice in single group. Terminally, 36 mice entered result analysis. ① MAD content:Serum MAD content in zuoguiyin group and single group were lower than that in senile control [(5.280±1.204) μmol/L and (5.886 2.717) μmol/L,(9.533 3.494) μmol/L, (q=3.641-4.657, P ＜ 0.05)]. Serum MAD content in zuoguiyin group and single group were basically same. ② SOD activity: SOD activity in zuoguiyin group and removal group were higher than senile group [(7.008±0.782) mkat/L and (6.989±0.809) mkat/L, (5.908±0.392) mkat/L,(q=3.641-4.657, P ＜0.05)]. SOD activity in zuoguiyin group and removal group were basically same and that in single group and senile control were basically same. ③ General anti-oxidation capacity: The general capacity of anti-oxidation in serum in zuoguiyin group and single group were stronger than that in senile control, that in removal group was weaker than senile control, but the differences were not significant (P ＞ 0.05).CONCLUSION: Zuoguiyin remarkably reduces MAD content and improves SOD activity in serum of senile mice. It is indicated that zuoguiyin acts remarkably on improving metabolism of free radical in senile body,strengthening SOD activity and reducing organic injuries caused by MAD accumulation.

Objective To observe the efficacy of the combination of moxibustion and pressing beans on auricular in the treatment of elderly patients with chronic diarrhea.Methods 45 elderly patients met the diagnostic criteria for diarrhea were divided into two groups,the treatment group (23 cases) received the treatment of combined moxibustion with ear pressure beans,the control group (22 cases) received traditional Chinese medicine treatment.The efficacy was observed and compared after two weeks.Results The effective rate reached 95.6％ in the treatment group,81.8％ in the control group (statistically significant difference,odds ratio 1.16).Conclusion Combined ear pressure beans with moxibustion treatment will receive a significant effect for the elderly patients with chronic diarrhea.The therapy is worth clinical application.

Objective:To explore the effect of zuoguiyin and its partial prescriptions on cellular immune function in senile mice.Methods:Healthy male ICR senile mice were divided into 4 groups at random: old contrast group, ZGY group, prepared rhizome of rehmannia(PROR) group and none prepared rhizome of rehmannia(NPROR) group. The senile mice had been drunk zuoguiyin and its partial prescriptions for 75 days, then observing the differences through thymic index, spleen index, activity of T lymphocyte and the level of IL-2 after using different drugs.Results:Acted by ZGY, ZGY had enhanced cellular immune function of senile mice, appearing that thymic index, spleen index, activity of T lymphocyte and the level of IL-2 were distinctly higher than those of the old contrast group. Compared to ZGY,prepared rhizome of rehmannia also enhanced the activity of T lymphocyte. However, it had no effect on thymic index, spleen index and the level of IL-2.So its effect on anti-senility was not better than ZGY. None prepared rhizome of rehmannia group had no distinct effect on those indexes.Conclusion:Zuoguiyin had an action of antisenility by improving cellular immune function.

ConclusionBushen-Yitalpowder adjuvant to progesterone therapy can improve the clinical outcome in patients with early threatened abortion.

Objective To investigate the value of modified NIHSS and MRI-PC-ASPECTS for the long-term prognosis in posterior circulation ischemic stroke. Methods Seventy eight patients with posterior circulation ischemic stroke were divided into two groups depended on MRS: good outcome group and bad outcome group. General information of patients was collected and vascular risk factors, NIHSS, MRI-PC-ASPECTS of the two groups were compared. Results The scores of admission NIHSS and highest NIHSS of bad outcome group were higher than that of good outcome group. The scores of MRI-PC-ASPECTS, T admission NIHSS (42-admission NIHSS) and T highest NIHSS of bad outcome group were lower than that of good outcome group (P<0.05). The areas under the ROC curves of MRI-PC-ASPECTS+T highest NIHSS, MRI-PC-ASPECTS, T highest NIHSS and T admission NIHSS were 0.907, 0.821, 0.870, 0.744, respectively (P<0.05). Conclusion NIHSS and MRI-PC-ASPECTS can predict the functional prognosis in patients with posterior circulation ischemic stroke.

Prognosis and treatment of primary Sj?gren′s syndrome with renal tubular acidosis

BACKGROUND: The total knee replacement is considered as one of the most effective and successful operations to cure terminal or severe gonarthritis. How to lower the revision rate as well as increace the effect of prostheses after the knee replacement should be solved urgently.OBJECTIVE: To retrospectively analyse the clinical applications and curative effects of different knee prostheses.DESIGN: Based on patients who accepted knee replacement, preoperative and postoperative condition was observed and compared so as to compare the postoperative effect of different types of knee prostheses replacements.SETTING: Department of Orthopedics, General Hospital of Chinese PLA.PARTICIPANTS: A total of 398 patients (523 knees) were selected from the Department of Orthopedics, General Hospital of Chinese PLA from January 2002 to January 2005, including 276 unilateral knee replacements (276 knees) and 122 bilateral knee replacements (244 knees). Patients were respectively diagnosed as osteoarthritis (OA), rheumatoid arthritis (RA), ankylosing spondylitis (AS), pigmented villonodular synovitis (PVNS), etc.METHODS: According to the pathogenetic condition, patients received total knee replacements with different knee prostheses. Types of knee prostheses: ① According to the replacing range, it could be divided into unicondylar prostheses and total condylar prostheses; total condylar prostheses could be subdivided into posterior cruciate ligament (PCL)-retaining and PCL-substituting prostheses. ②According to the degree of mechanical constraint, it could be divided into unconstrained, semiconstrained or fully constrained prostheses. ③ According to whether imitating meniscus-function, it could be divided into tibial plateau rotatable sliding type and fixed type. Follow-up was conducted on patients that mentioned above after half a year. Knee joints were scored by using knee joint scoring system of American special surgical hospital (HSS scoring with the total score of 100 points, those above 85 were considered as excellent; 70-84 as good;60-69 as fair; below 60 as poor). Feller scoring (total score of 30 points; the higher the points were, the better the symptom was) criteria was used in patellar scoring. Investigation and comparison on pain-degree of anterior region of knee,range of motion of knee joint and the stabilization were done during the follow-up, ap and lateral views of patella from 30 degrees and 90 degrees were taken in radiography.MAIN OUTCOME MEASURES: Preoperative and postoperative scores of HSS, patella, anterior pain of knee, function of patella, the maximum flexion and tibiofemoral angle.RESULTS: Follow-up was conducted in 372 patients (490 knees) with the follow-up rate of 93.4%. ①Therapeutic effect:Excellent and good rate of the operation was 89%. Pain and function of patients after operation were obviously ameliorated, effect on pain-amelioration and range of motion of knee joint activation were significant. ② Score of HSS, patellar,anterior pain of knee, function of patellar and the maximum flexion were markedly increased than those before operation (P ＜ 0.01). ③ There were no marked significances in comparison of score of HSS, patellar, anterior pain of knee, function of patellar, the maximum flexion and tibiofemoral angle on different knee prostheses replacements (P ＞ 0.05).CONCLUTION: Prostheses should be chosen carefully and appropriately according to the indications, contraindications,anticipated attainable functions, service life as well as pathogenetic conditions, and then satisfactory curative effect will accordingly be achieved.

Objective To discuss the relationship between heart rate (HR), rate of perceived exertion (RPE) and oxygen consumption in therapeutic exercises for stroke patients. Methods Eighteen stroke patients a-ble to walk independently participated in the test. K4b2 Pulmonary Function Equipment was used to record their heart Rates(min-1)and specific oxygen consumption(ml·min-1·kg-1)during the following exercises:relaxed sitting,sit-to-stand transfers, leaning against a wall and elevating the hips (strength training of the gluteus maximus) , raising the unaffected leg while the affected leg is weight bearing, raising the affected leg while the unaffected leg is weight bearing, climbing up and down stairs, and walking 60 meters. RPE was surveyed after each exercise. Results The correlation between HR and oxygen consumption was moderate (r = 0.618, P≤0.001), but it was weak between RPE and oxygen consumption (r = 0.325 ,P≤0.001). Conclusion Heart rate is a better index than RPE for eval-uating exercise intensity with stroke patients able to walk independently.

Objectives To analyze the main pathogen of otitis media and antibiotics resistance of clinical bacterial isolates in pediatric patients. Methods Secretion specimens from 164 cases of otitis media were cultured. Antimicrobial susceptibility was determined. Results were analyzed according to the guidelines of Clinical and Laboratory Standard In-stitute (2012). WHONET 5.6 software was used to analyse the data. Results Pathogens were cultivated in 121 ear secretion specimens from 164 cases of otitis media and the positive rate was 73.8%. There were 9 cases of mixed bacterial infection, accounting for 5.5%. 130 strains of pathogens were isolated from middle ear secretion and the main pathogens were bacteria (83.1%) and fungus (16.9%). Among bacteria, 50 (46.3%) were Streptococcus pneumoniae and 21 (19.4%) Staphylococcus aureus. Among fungus, 17 (77.3%) were Candida spp and 5 (22.7%) Aspergillus spp. By age, the rates of infection caused by Streptococcus pneumoniae in infancy and early childhood were markedly higher than those in preschool and school-age, respectively (P<0.05). The no-susceptibility rate of Streptococcus pneumoniae to penicillin was 76.0%. The prevalence of meticillin-resistant Staphylococcus aureus (MRSA) was 14.3%. Conclusions Proper treatment depends on the secretion culture and drug sensitive test due to various pathogens of otitis media.
