The paper aims to elucidate and establish a new mathematic model: the total quantum statistical moment standard similarity (TQSMSS) on the base of the original total quantum statistical moment model and to illustrate the application of the model to medical theoretical research. The model was established combined with the statistical moment principle and the normal distribution probability density function properties, then validated and illustrated by the pharmacokinetics of three ingredients in Buyanghuanwu decoction and of three data analytical method for them, and by analysis of chromatographic fingerprint for various extracts with different solubility parameter solvents dissolving the Buyanghanwu-decoction extract. The established model consists of four mainly parameters: (1) total quantum statistical moment similarity as ST, an overlapped area by two normal distribution probability density curves in conversion of the two TQSM parameters; (2) total variability as DT, a confidence limit of standard normal accumulation probability which is equal to the absolute difference value between the two normal accumulation probabilities within integration of their curve nodical; (3) total variable probability as 1-Ss, standard normal distribution probability within interval of D(T); (4) total variable probability (1-beta)alpha and (5) stable confident probability beta(1-alpha): the correct probability to make positive and negative conclusions under confident coefficient alpha. With the model, we had analyzed the TQSMS similarities of pharmacokinetics of three ingredients in Buyanghuanwu decoction and of three data analytical methods for them were at range of 0.3852-0.9875 that illuminated different pharmacokinetic behaviors of each other; and the TQSMS similarities (ST) of chromatographic fingerprint for various extracts with different solubility parameter solvents dissolving Buyanghuanwu-decoction-extract were at range of 0.6842-0.999 2 that showed different constituents with various solvent extracts. The TQSMSS can characterize the sample similarity, by which we can quantitate the correct probability with the test of power under to make positive and negative conclusions no matter the samples come from same population under confident coefficient a or not, by which we can realize an analysis at both macroscopic and microcosmic levels, as an important similar analytical method for medical theoretical research.

BACKGROUND:In recent years, minimal y invasive percutaneous plate fixation has been a selectable method to repair fracture of lower limbs, especial y complex fracture of lower limbs. Its advantages are to reduce the damage to soft tissues, and do not destroy bone nutrient supply vessels. However, there is no unified criterion to select which method in the repair of distal tibial fractures. OBJECTIVE:To observe clinical effects of minimal y invasive percutaneous plate fixation versus open reduction and plate fixation in the repair of distal tibial fractures. METHODS:A total of 60 cases of distal tibial fractures treated with minimal y invasive percutaneous plate osteosynthesis (n=35) and open reduction and plate fixation (n=25) were selected. The time of surgery was identified by evaluating soft tissue. We should pay attention to the protection of soft tissue in surgery and reasonable fixation method should be selected. After fixation, we guided patients to do active early functional exercise. They were fol owed up and regularly received X-ray reexamination. Operation time, weight loading time, healing time and functional recovery were observed and the clinical therapeutic effects of the two methods were compared. RESULTS AND CONCLUSION:Al patients were fol owed-up after surgery. They were fol owed up for 3 to 15 months. No significant difference in healing time of type A fracture was detected between minimal y invasive percutaneous plate fixation and open reduction and plate fixation. The healing time of types B and C fracture was better in minimal y invasive percutaneous plate fixation group than in open reduction and plate fixation group. These results indicated that minimal y invasive percutaneous plate fixation in repair of tibial fractures, especial y distal complex tibial fractures, is an effective method. The healing rate of fracture was high, but postoperative complications were less.

Objective To observe the incidence,clinical types,and prognosis of pulmonary involvement in children with systemic lupus erythematosus(SLE),and to probe the relationship between the relative factors.Methods The clinical data of 61 children with SLE,who treated in Children's Hospital of Shanghai from Jan.2006 to Dec.2011 were analyzed retrospectively.The lung manifestations of the patients were classified according to their clinical symptoms and signs,and lung imaging examination (chest X-ray and CT).Other data of the SLE patients with lung injury or without lung injury were collected,including the course of the disease,activity index [SLE disease activity index (SLEDAI) scoring 0-4 was divided into no activity,5-9 was divided into low activity,10-14 was divided into moderate activity,and more than 15 as severe activity],blood sedimentation,the values of serum complement and the positive rate of dsDNA in autoantibody,and a comparison was made and statistical analysis was performed.Results Pulmonary injury occurred in 17 cases with an incidence rate of 27.9％ (17/61 cases),and the average course of the disease was (8.76 ± 6.96) months.The clinical manifestations of 17 cases included fever,cough,dyspnea,hypoxemia,chest pain,lower breath sound,and lung rale,which were not non-specificity.According to imageological examination,in 17 cases there were 2 cases with pulmonary hypertension (the incidence rate was 11.8％),4 cases with acute lupus pneumonitis (the incidence rate was 23.5％),6 cases with interstitial pneumonia (the incidence rate was 35.3％),7 cases with lesion of pleura (the incidence rate was 41.2％),10 cases with pulmonary infection (the incidence rate was 58.8％).There were no statistical differences between patients with and without lung injury(infectious and non-infectious)in the course,the values of serumn complement,the positive rate of dsDNA and activity index.Lung lesions of the 17 patients recovered quickly after early diagnosis and active treatment.Conclusions Pulmonary manifestation in children with SLE is not uncommon,and it can happen at any stage of the disease,not just on the stage of lupus activity,but it usually indicates disease was not controlled.Pulmonary manifestation of SLE in children involve many parts of lung,including pulmonary parenchyma,interstitial,blood vessels,pleura,etc.Early diagnosis and active treatment can improve the short-term prognosis of lung injury with lupus,and long-term outcome remains to be observed.

BACKGROUND:As for patients with one-side backleg pain who were candidates for surgery treatment of lumbar intervertebral disc herniation, the common treatment includes lumbar vertebral plate opening and decompression, and laminectomy in combination with compression and bilateral pedicle screw fixation. However, these therapeutic approaches are not satisfactory. OBJECTIVE:To explore the feasibility and efficiency of single-side lumbar interbody fusion and unilateral pedicle screw fixation for treatment of lumbar intervertebral disc herniation patients with one-side backleg pain. METHODS:Forty patients with single-side lumbar disc herniation, suffering from unilateral backleg pain, were recruited from Shihezi People’s Hospital, China and were treated with single-side lumbar interbody fusion and unilateral pedicle screw internal fixation. The neurological function of patients was assayed using Japanese Orthopaedic Association score system before and after treatment, the improvement rate and excellent/good rate were calculated. Suk criterion was used to determine fusion status. RESULTS AND CONCLUSION:The mean fol ow-up period for 40 patients was ranging from 6 months to 60 months. Al incisions healed wel , with no infection. The Japanese Orthopaedic Association score after 6 months of treatment was significantly higher than that before treatment (P<0.05), with the excellent and good rate up to 88%. According to Suk criterion, 38 patients achieved bone graft fusion or possible fusion, with interbody fusion rate 95%, as revealed by radiographic and CT evidence. The remaining two patients were detected fusion at 9 months after treatment. Our findings indicate that, single-cage lumbar interbody fusion combined with single-side pedicle screw fixation is the feasible surgical technique and provides satisfactory effects in treating single-side lumbar disc herniation.

OBJECTIVETo explore the mechanisms of Qianjing Decoction in the treatment of oligoasthenospermia (OAS).

METHODSWe randomly divided 100 SPF male rats into five groups of equal number: normal, model, Huangjingzanyu, levocarnitine, and Qiangjing. OAS models were established in the animals followed by intragastrical administration of normal saline, ornidazole, Huangjingzanyu Capsules (200 mg per kg body weight per day), levocarnitine (100 mg per kg body weight per day), and Qianjing Decoction (10 g per kg body weight per day), respectively, qd, for 4 successive weeks. Then, we detected the concentration and motility of the epididymal sperm, obtained the contents of superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GSH-Px), lactate dehydrogenase (LDH), α-glucosidase, and fructose in the epididymis, and determined the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and succinate dehydrogenase (SDH) in the epididymal tissue of the rats by real-time PCR.

RESULTSThe concentration and motility of the epididymal sperm in the model, Huangjingzanyu, levocarnitine, and Qianging groups were (35.34 ± 4.22) x 10(6)/ml and (40.04 ± 7.05)%, (48.12 ± 5.56) x 10(6)/ml and (62.46 ± 7.12)%, (47.14 ± 4.87) x 10(6)/ml and (63.23 ± 6.34)%, and (50.25 ± 5.08) x 10(6)/ml and (66.34 ± 7.58)%, respectively, all significantly lower than in the normal group ([53.05 ± 4.55] x 10(6)/ml and [70.20 ± 8.54]%) (P < 0.05), but remarkably higher in the Huangjingzanyu, levocarnitine, and Qiangjing groups than in the model rats (P < 0.05). Compared with the thinned epididymal lumen walls, decreased sperm count, and disorderly and loose arrangement of the lumens in the OAS models, the rats in the Huangjingzanyu, levocarnitine, and Qiangjing groups showed evidently thicker epididymal lumen walls, with the lumens full of sperm cells and arranged regularly and compactly, similar to those of the normal rats. The levels of SOD and GSH-Px were significantly lower but that of MDA markedly higher in the model rats ([84.12 ± 23.25], [10.56 ± 3.02], and [14.04 ± 2.06] nmol/mg) than in the normal group ([110.04 ± 19.56], [17.25 ± 3.56], and [8.87 ± 1.35] nmol/mg) (P < 0.05), while the former two indexes remarkably higher and the latter one significantly lower in the animals treated with Qiangjing Decoction ([120.56 ± 23.68], [16.34 ± 3.12], and [8.45 ± 1.56] nmol/mg), Huangjingzanyu Capsules ([115.34 ± 21.35], [15.23 ± 3.67], and [8.33 ± 1.54] nmol/mg), and levocarnitine ([116.67 ± 22.67], [15.35 ± 3.45], and [8.05 ± 1.78] nmol/mg) than in the models (P < 0.05). The levels of fructose, LDH and α-glucosidase were decreased markedly in the OAS models ([100.22 ± 12.12] mg/[ ml x g], [322 ± 46.13] U/[ ml x g], and [10.48 ± 2.33] U/[ml x g]) as compared with the normal rats ([128.12 ± 13.45] mg/[ml x g], [428 ± 35.12] U/[ml x g], and [15.34 ± 3.12] U/[ ml x g]) (P < 0.05), remarkably higher in the rats treated with Qiangjing ([130.23 ± 13.67] mg/[ml x g] [455 ± 51.50] U/[ml x g], and [18.56 ± 4.67] U/[ml x g]), Huangjingzanyu ([124.16 ± 14.02] mg/[ml x g], [ 419 ± 43.14] U/[ml x g], and [17.64 ± 4.08] U/[ml x g]), and levocarnitine ([123.34 ± 14.02] mg/[ml x g], [430 ± 31.80] U/ [ml x g], and [16.85 ± 5.55] U/[ml x g]) than in the models (P < 0.05). The Nrf2 mRNA expression was significantly reduced in the models as compared with the normal rats (P < 0.05) but remarkably increased in the Huangingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05). The SDH mRNA expression was significantly lower in the model than in the normal rats (P < 0.05) but markedly elevated in the Huangjingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05), remarkably higher in the Qiangjing than in the Huangjingzanyu group (P < 0.05).

CONCLUSIONOrnidazole induces OAS in rats, which is closely associated with excessive oxidation and energy metabolism dysfunction. Qiangjing Decoction can improve and even reverse ornidazole-induced OAS in rats as well as improve the ultrastructure of their testicular and epididymal tissues. Antioxidation and improvement of energy metabolism are probably the action mechanisms of Qiangjing Decoction in the treatment of OAS.

Objective To evaluate the safety and feasibility of laparoscopic right hemi-hepatectomy for hepatolithiasis.Methods The clinical data of 3 patients who underwent laparoscopic right hemi-hepatectomy were analyzed retrospectively.Results In 2 patients the operation was performed successfully.The operative time was 340 min and 300 min,and the intraoperative blood loss was 800 ml and 400 ml.There was no need for blood transfusion.There was a small amount of bile leakage (30-60 ml/day) in these 2 patients.The postoperative hospital stay was 9 d and 11 d.The third patient was converted to open surgery because of profuse bleeding.All the 3 patients recovered well from surgery.Conclusions Total laparoscopic right hemi-hepatectomy for hepatolithiasis was safe and feasible.

Background Normal adult optic disc rim width follows inferior ≥ superior ≥ nasal ≥ temporal (ISNT) rule.Analysis of the optic disc structural parameters with Heidelberg retina tomograph (HRT) can understand whether ISNT principle is suitable to other optic disc structure parameters.Objective This study was to investigate the characteristics of optic nerve head structure parameters in normal Chinese adults.Methods The parents of twins who participated Guangzhou Twin Eye Study were enrolled in Zhongshan Ophthalmic Center from 2006 June to 2011 August.All subjects received the routine eye examinations,including visual acuity,slit lamp microscope,direct ophthalmoscope examination,auto-refraction examination and HRT Ⅲ examination.All data from the right eyes were collected and analyzed.HRT values from different quadrants of optical nerve head were compared with one-way analysis of variance,and the multiple comparison between quadrants was carried out by Bonferroni test.The differences of optical nerve head parameters in different gender were analyzed using independent sample t test and Bland-Altman test.Results In this study,1672 eyes of 1672 subjects were included,with the 759 male and 913 female persons and average age of (41.8±5.3)years.No significant differences were seen in the disc area (DA)between the superior and inferior,as well as the nasal and temporal quadrants among the subjects (P＞0.05).In addition,there were not significantly different in the rim area (RA) between the superior and nasal disc as well as the rim volume (RV) among the inferior,superior and nasal disc (P＞O.05).However,significant differences were found in the cup area (CA),cup/disk area ratio (C/DAR),cup volume (CV),mean cupdepth (MCD),maximum cup depth (MxCD),height variation contour (HVC),cup shape measure (CSM),mean retinal nerve fiber layer thickness (mRNFLT) and retinal nerve fiber layer cross section area (RNFLcsa) among the different quadrants (P＜0.001).The local differences from only DA and RA complied with an ordination of the ISNT rule.The values of DA,CA,C/DAR,CV,MCD,MxCD from male individuals were higher,but those of the RV,HVC,mRNFLT RNFLcsa were lower in comparison with female individuals.Nevertheless,all the differences were ＜ 0.1 with a maximal mean difference in DA and CA (both 0.07 mm2).Conclusions The optical nerve head configurations measured by HRT have different distributing characteristics in four quadrants in normal adults.Most parameters show the higher values in the inferior and superior than those in nasal and temporal of disc,but DA and RA meet ISNT rule.The differences of most parameters between male and female subjects can be ignored.
