Objective To investigate the predictive value of T,B,and NK lymphocyte subsets jointly detected in poor prognosis in patients with sepsis.Methods Totally 101 patients with sepsis were enrolled for prospective study.The percentages of lymphocyte sub-populations in peripheral blood were detected within 48 h after admission.The outcomes of patients during hospitalization were observed by follow-up study.The predictive value of lymphocyte sub-populations jointly detected in death risk was assessed.Results The percentages of CD3,CD3 +/CD4 + in patients with septic shock were lower than those in patients with mild/moderate sepsis and severe sepsis.The percentages of CD3+/CD8+,CD3-/CD19 +,CD4 +/CD8 + in patients with severe sepsis and septic shock were lower than those in patients with mild/moderate sepsis.The percentage of CD (16 +56) + in severe sepsis and septic shock was higher than that in mild/moderate sepsis group (P ＜ 0.05).The total number of monocytes in the deaths was higher than that in survivals.The percentages of CD3,CD3-/CD19 +,CD3 +/CD4 +,CD4 +/CD8 + were lower in deaths than those in survivals (P ＜ 0.05).The CD3-/CD19 +,CD3 +/CD8 and CD4 + / CD8 + were protective factors against sepsis with their OR values of 0.235,0.006 and 0.108,respectively.The ROC curve of lymphocyte subsets jointly detected,APACHE]] score and SOFA score to predict the risk of death were 0.993,0.877 and 0.848,respectively.The misjudgment rate of discriminating disease severity function of lymphocyte subgroups jointly detected was 19.8％,and that of outcomes was 4％.Conclusion The percentages of lymphocyte sub-populations in patients with sepsis is abnormal,and therefore,the lymphocyte subgroups jointly detected has value in the judgment of disease severity and prognosis in patients with sepsis.

BACKGROUND: Unicompartment knee arthroplasty (UKA) is gradually applied in the treatment of knee osteoarthritis, and the management of perioperative blood loss is a hot spot in clinical research. It is very important to control perioperative blood loss and changes in hemoglobin level for postoperative rapid recovery. OBJECTIVE: To investigate the changes in the blood-related indexes during the management of perioperative blood loss in UKA, so as to provide technical reference and data reference for clinical application. METHODS: Clinical data 70 patients undergoing UKA at the Department of Bone and Joint of Guangdong Provincial Hospital of Chinese Medicine from January to December 2015 were analyzed retrospectively, and received the management of perioperative blood loss. The operation time, intraoperative blood loss, postoperative drainage volume, total blood loss and rate of blood transfusion were recorded; the preoperative hemoglobin, albumin, coagulation indexes, D-dimer, erythrocyte sedimentation rate and C-reactive protein were investigated. The effect of operation on the postoperative blood loss and drainage volume was analyzed. RESULTS AND CONCLUSION: (1) The operation time was (89.36±19.89) minutes, intraoperative blood loss was (39.71±23.64) mL, postoperative drainage volume was (56.21±34.21) mL, and rate of autologous blood transfusion was 0. (2) The operation time exerted no effect on the intraoperative blood loss (P=0.685 7), but affected on the postoperative drainage volume (P=0.021 6). (3) The total postoperative blood loss was little, and the blood loss did not differ significantly at 3 hours, 1, 3 and 7 days postoperatively (P > 0.05). (4) There was a slight decline in hemoglobin on days 1-3 after surgery, and then returned slowly; the erythrocyte sedimentation rate and C-reactive protein increased rapidly within 1 day after surgery and declined within 1-3 days; the D-dimer rapidly increased on day 1 after surgery, then rapidly decreased on days 1-3, and then slowly increased on days 3-7; the plasma total protein and albumin were stable and fluctuated in the normal range within 1-3 days. (5) These results suggest that the UKA had short operation time, few total blood loss and slight fluctuation, and the blood-related indexes exhibit different fluctuations. Moreover, the preoperative management of blood loss can reduce the total blood loss and rate of blood transfusion..

OBJECTIVETo observe the biocompatibility of new biomaterials porous calcium phosphate (CPC) and ectopic bone formation of CPC with bone marrow stromal cells (BMSCs).

METHODSThe BMSCs were cultured from Beagle dog and combined with the porous CPC with the best concentration after transfect green fluorescent protein (GFP). The adhesion and growth of BMSCs on CPC were observed under inversion, fluorescence and scanning electron microscopy. The ectopic bone formation were observed at the 8th week after CPC and BMSCs were implanted subcutaneously into nude mice.

RESULTSWhen BMSCs with CPC were cultured at the 1st day, cells were climbing out from CPC with normal morphology. At the 7th day cells can be seen protruding pseudopods, secretion of matrix. Bone formation could be seen histomorphologically at the 8th week.

CONCLUSIONPorous CPC has good biocompatibility and is an ideal scaffold material for bone tissue engineering.

OBJECTIVETo compare the effect between open reduction internal fixation with Kirschner nails and miniplates in the treatment of Mason type II and III fractures of radial head.

METHODSFrom May 2004 to March 2010, 50 cases of Mason type II and III fractures of radial head were treated with Kirschner nails or mini-plates. In Kirschner nail group, there were 13 males and 10 females (mean age 42.5 +/- 0.7 years), and 14 cases of Mason type II and 9 cases of Mason type III fracture. In mini-plate group, there were 17 males and 10 females (mean age 41.7 +/- 0.5 years), and 16 cases of Mason type II and 11 cases of Mason type of III fracture. The excellent and good rates according to the Broberg and Morrey Elbow Score, and the rate of ectopic ossification were compared.

RESULTSAll the patients were followed up for 12-24 (mean 16.5 +/- 1.3) months. The Broberg and Morrey Elbow Score of mini-plate group was (90.5 +/- 11.6), and that of Kirschner nail group was (70.6 +/- 11.3). The result of mini-plate group was excellent in 15 cases, good in 9 cases, fair in 2 cases, and poor in 1 case; The result of Kirschner nail group was excellent in 8 cases, good in 9 cases, fair in 3 cases and poor in 3 cases. The effect of mini-plate group was better than that of Kirschner nail group. There was no statistic difference in the rate of ectopic ossification between the two groups (P > 0.05).

CONCLUSIONFractures of radial head can be well treated with open reduction and internal fixation by mini-plates, which offer better results than Kirschner nails.

A naphtha catalytic reforming unit with four reactors in series is analyzed. A physical model is proposed to describe the catalytic reforming radial flow reactor. Kinetics and thermodynamics equations are selected to describe the naphtha catalytic reforming reactions characteristics based on idealizing the complex naphtha mixture by representing the paraffin, naphthene, and aromatic groups by single compounds. The simulation results based above models agree very well with actual operation unit data.

OBJECTIVETo investigate the effects of decompresion through double-incision of foot dorsum on the treatment of osteofascial compartment syndrome of the foot under the monitoring of saturation of blood oxygen.

METHODSFrom January 2000 to June 2007, 26 cases of osteofascial compartment syndrome of the foot were decompressed through double-incision of foot dorsum under the monitoring of saturation of blood oxygen, and relaxation suture or skin grafting were operated within 3 to 10 days after decompressing. Among them, 22 patients were males and 4 were females, with an average age of 36.3 years old ranging from 22 to 68 years. According to AOFAS system, the pain, function, autonomic activities and support were evaluated.

RESULTSAll patients were followed-up for from 6 to 43 months with the average of 19 months. All patients were healed. According to AOFAS system, the total scores increased from preoperative (30.4 +/- 8.02) to postoperative (92.5 +/- 5.0) (t = 3.13, P < 0.01); the results were excellent in 21 cases, good in 4 and poor in 1.

CONCLUSIONThe patients of fracture-dislocated, swelling and injured in the soft tissue because of severe violence should observed closely on osteofascial compartment syndrome of the foot early. Feet are operated and thoroughly decompressed as soon as it is diagnosed as the compartment syndrome. Osteofascial compartment syndrome of the foot decompressed by foot dorsum double-incision is convenient and satisfied, and the operation is performed by internal fixation if it is displacedly fractured at the same time.

OBJECTIVETo explore the elastic lamina degradation and the collagen remodeling of aortic artery as well as oxides stress and inflammation of the apolipoprotein (Apo E) deficient mice with or without experimental hypertension.

METHODSEighty male Apo E deficient mice were fed with high-fat diet beginning at six weeks of age. At 8-week old, they were randomly divided into hypertension group and control group (n=40 each), the mice in hypertension group were subjected the suprarenal aortic constriction operation and then randomly divided into two subgroups: 15 weeks age and 30 weeks age groups. At the end of experiment, the vascular elastic lamina degradation and the content of collagen were determined by morphological method, plasma ICAM-1 level was measured by ELISA, and the rennin activity measured by radioimmunoassay, the superoxide anion detected by fluorescence, the MOMA-2 observed by immunofluorescence in all animals. mRNA expression of NF-κB P65 and MMP9 was detected by real-time PCR.

RESULTIn 15-week old group, the elastic lamina degradation Grade II and the intima-media thickness in the hypertension group were significantly higher than in the control group [(5.4±3.3)% vs. (8.9±2.5)%, P<0.05; (98.66±18.90) µm vs. (70.08±11.71) µm, P<0.05]. In 30-week old group, the elastic lamina degradation Grade III, the III type of collagen and the intima-media thickness were also significantly higher than in the control group [(15.2±3.7)% vs. (8.1±3.3)%, P<0.01; (23.00±7.73)% vs. (11.00±3.82)%, P<0.05; (147.31±22.60) µm vs. (103.98±17.21) µm, P<0.01]. The level of ICAM-1 in hypertension group was significantly higher than that of control group in both 15-week old and in 30-week old mice [(46.3±3.7) µg/ml vs. (40.6±5.7) µg/ml, P<0.05; (56.0±3.1) µg/ml vs. (45.2±2.8) µg/ml, P<0.05]. The superoxide anion, the MOMA-2, mRNA expression of NF-κB P65 and MMP9 in the hypertension group were significantly higher than in the control group in both 15-week old and in the 30-week old mice. The increase in hypertension group was more pronounced in the 30-week old mice than in the 15-week old mice.

CONCLUSIONThe elastic lamina degradation and the collagen remodeling of aortic artery as well as oxides stress and inflammation are more significant in the Apo E deficient mice with hypertension than in control Apo E deficient mice.

OBJECTIVETo investigate the differences in semen quality at different times of reanalysis and the correlation of sperm DNA fragmentation index (DFI) with sperm motility alteration using semen samples completely liquefied and normal in initial examination.

METHODSWe analyzed 127 semen samples up to the inclusion criteria with the computer-assisted semen analysis (CASA) system at 15, 30 and 60 min after semen collection, and obtained sperm morphology parameters and DFI by Shorr staining and acridine orange test (AOT) , respectively.

RESULTSSperm concentration, and the percentages of grades a and b sperm showed no statistically significant differences at the three time points (P > 0.05). The percentages of grades a + b and a + b + c sperm were significantly higher at 15 min than at 30 and 60 min after semen collection (P < 0.05), but with no significant difference between the latter two time points (P > 0.05). The incidence of alternation from normal to abnormal in at least one index of sperm motility at different times was 25.2%, but there were no significant differences in sperm DFI and morphology between the normal and abnormal groups (P > 0.05). Among the altered parameters of sperm motility from 15 to 60 min, the percentages of grades a, a + b and a + b + c sperm were all positively correlated with sperm DFI (P < 0.05).

CONCLUSIONSemen samples completely liquefied within 15 min after collection and normal in initial examination, when reanalyzed at 30 and 60 min, showed significant decreases in the percentages of grades a + b and a + b + c sperm, but not in the percentages of grades a and b sperm, and the parameters of sperm motility might be abnormal. Thus, at least 2 sperm analyses are required for a comprehensive evaluation of fertility. Significant difference between the results of the two analyses, and particularly a markedly reduced percentage of rapidly progressive sperm, might indicate sperm DNA damage, and thus the necessity of sperm DNA damage detection.

OBJECTIVETo investigate the applied anatomy of the proximal posterior interrosseous artery perforator flap (PIAP) and report the clinical results of repairing the soft tissue defects in hands.

METHODSBetween September 2007 and January 2011, 21 patients with 24 soft tissue defects in hands were repaired with the free proximal PIAP flap transplantation. The size of the flaps ranged from 2.0 cm x 1.5cm to 7cm x 5cm. The longest length of these flaps was 9 cm. 9 flaps were dissected with one additional superficial vein to anastomose with the superficial vein at the recipient sites.

RESULTS19 flaps survived completely. Bubbles and violet color happened in 4 flaps which survived finally after partial suture removal. Flap necrosis occurred in one flap. The clinical results were satisfactory after 6-25 months of following-up, and the scars at the donor sites were not obvious.

CONCLUSIONSThe free PIAP flaps have constant, reliable blood supply, and good texture. It is a good option for repairing soft-tissue defects in the hands.
