A total of 65 patients of condyloma acuminatum (CA) received cryotherapy plus 5-aminolevulinic acid-photodynamic therapy (ALA-PDT) or ALA-PDT alone.During cryotherapy,handling was gentle with a moderate depth.The nursing of PDT was both meticulous and comprehensive.Patients with adverse reactions received Kangfuxin liquid for wet packing and topical antibiotic ointment.The combination group received cryotherapy for 2 sessions and then PDT for 1-3 sessions while PDT was administered for 1-4 sessions in single PDT group.Then all patients received PDT once for consolidation therapy.For groups 1 and 2,the effective rates were 83％ and 70％ and the recurrent rates 17％ and 30％ respectively.Cryotherapy plus ALA-PDT is feasible for CA and it offers better efficacies and lower recurrent rates.And comprehensive,meticulous and comfortable nursing may achieve clinical efficacies,reduce the recurrent rate and minimize discomforts during treatment.

Objective To explore the clinical features of ABO hemolytic disease in newboms,red blood cell glucose-6-phosphate dehydrogenase(G-6-PD) deficiency and the combined. Methods In the study, 160 cases of ABO hemolytic disease in newborn (ABO group) ,219 cases of G-6-PD deficiency(G6PD group) ,52 cases of the combined(ABO + G6PD group). The three groups were analyzed. Results The hemoglobin in the G6PD group ( (159. 7 ± 24.9) g/L) was significantly higher than in the ABO group ((150. 2 ± 23.0) g/L) and ABO + G6PD group( (149. 2 ±22. 8) g/L) (P < 0. 01). TBIL in the G6PD group ( (419. 0 ± 152. 9)μmol/L) was significantly higher than that in the ABO group ( ( 355. 4 ± 113. 2 )μmol/L) ( P < 0. 01). The Jaundice dissipated time in the G6PD group were significantly longer than ABO group ( ( 9.4 ± 2. 3) d vs. ( 8. 2 ± 2. 2 ) d) ( P < 0. 01 ) . In the ABO + G6PD group, the Jaundice dissipated time, time of phototherapy and number of phototherapy was (12. 0 ± 2. 7)d,(43. 2±16. 0)h and (3.5 ± 1. 2) times, which was significantly longer (or more) than those of the ABO group ((8. 1 ±2.2)d,(36. 1 ±15.9)h and (2. 6 ±1. 2)times) and G6PD group( (9.4 ±2. 3)d,(37. 6 ± 17. 3)h and (2. 8 ± 1. 3) times) (P<0. 05). The incidence of the bilirubin encephalopathy, hypocalcemia rate in the G6PD group (16. 0% ,32.9% ) were significantly higher than those in the ABO group(6. 9% and 20.0% ) (P <0. 05 ) . However, the incidence of anemia (23. 3% ) in the G6PD group was significantly lower than that in the ABO group (40. 0% ) and ABO + G6PD group (51.9%) ( P < 0. 01) . Conclusions In the newborns with ABO hemolytic disease and G-6-PD deficiency,the time jaundice appear,the degree of jaundice,bilirubin encephalopathy rate were not significantly different from those in the ABO hemolytic disease and G-6-PD group, but the jaundice persisted longer,and more easily repeated. Compared to the neonatal ABO hemolytic disease, the degree of jaundice, jaundice persisted longer in the G-6-PD deficiency,bilirubin encephalopathy is more likely to occur,whereas the incidence of anemia is much lower.

Italian medical imaging education includes two parts: training for radiologists and for radiologic technologists. To be a radiologist, the six-year medical students after graduation must complete specialty training in radiology and pass the examination. Radiologic technologists are selected from the three-year bachelor graduates of medical imaging technology. There are basic medical science courses, cultural practice and clinical practice in medical college every year. Continuing medical imag-ing education includes lectures, case discussions and other forms. Radiologists are required to master all kinds of imaging techniques, working as clinical rotation in every section of medical imaging depart-ment. Patients need to make an appointment before having the medical imaging examination. Through the analysis of the characteristics of Italian medical imaging teaching and clinical patterns, the author puts forward the suggestion of putting emphasis on medical imaging curriculum reform, the full imple-mentation of the early clinical contact, and at the same time improving the professional medical image training mode to improve the radiologists' clinical ability.

Objective To discuss the anatomy,manufacture,merit and demerit of dorsum pedis flap based on anatomic observation and comprehension using free dorsum pedis flap to repair the coloboma of oromaxillo-facial region soft tissue.Methods The courser and disposition of the skin blood vessel and nerve of dorsum of foot of 22 sides of adult cadaver lower limbs were dissected and observed under naked eye and operation microscope. 2 cases got troubled with oromaxillo-facial region malignant tumor,who were prepared 9.5 cm?7.5 cm and 8 cm?6 cm size of free dorsum pedis flap. The site of blood supply and recipient was anastomosed by blood vessel and nerve,and the coloboma of soft tissue was primary repaired after the operation of oromaxillo-facial region malignant tumor. Results Blood circulation of dorsum pedis flap was provided by dorsalis pedis artery,great saphenous vein and small saphenous vein,and fibular nerve was sensory nerve. During two years of follow-up visit,the two cases whose skin flaps were take were satisfactory with the reparation,and tumor recurrence did not take place. Conclusion The blood supply of free dorsum pedis flap is reliable,and it can become ideal skin flap to repair the soft tissue coloboma of oromaxillo-facial region.

Objective To explore the dynamic changes and the meaning of T lymphocyte subpopulation in peripheral blood and its clinical significance in patients with acute cerebral infarction.Methods The numbers of CD3 +,CD4 + and CD8 + T lymphocyte in peripheral blood were examined with flow cytometry in 20 patients with acute cerebral infarction(CI) at the 3rd,5th,7th and 14th day after the onset.Results The numbers of CD3 + and CD4 + T lymphocytes and the ratio of CD4 +/CD8 + in the patients with acute CI were lower than those in normal group at the 3rd and 5th day after the onset (P0.05).Conclusion The immunological function of the cells in the patients with acute CI decreased obviously at the 3th and 5th day, and then restored partly at the 7th day, at last restored completely at the 14th day after the onset. It suggests that the focus time for the prevention of infective complications is in 10 days after the acute CI.

Objective To investigate the role of ribosomal protein S7(rpS7) in the defense of Anopheles dirus against infection. Methods rpS7 was amplified from Anopheles dirus hemocytes with degenerated primers designed according to the conservative region of S7, rpS7 was then cloned using T/A cloning kit and the inserted fragment was sequenced. The difference of the transcript abundance of rpS7 from Anopheles dirus hemocyte among non-blood-fed (N), normal-blood-fed (B) and Plasmodium yoelii infected groups (I) was also analyzed by RT-PCR and gel scanning system at d1, d2, d3, d4, d7 and d11 after blood feeding. Results There is no significant difference of rpS7 signal between the three groups. Conclusion Anopheles dirus S7 can be used as an internal control to study the role of Anopheles dirus related immune factors in Plasmodium infection.

Objective:To investigate the role of blockade of CD40 ligand-CD40 costimulatory pathway by anti-CD40L mAb on T lymphocytes typing and cytokines, and provide the experimental clues of inducing donor-specific T cell anergy.Methods:To monitor primary MLR, C57BL/6 H-2b spleen T cells were isolated as responder cells, and BALB/C H-2d spleen cell as stimulator cells. Anti-CD40L mAb was added to primary MLR cultures(termed anti-CD40L mAb group), and in control group(no anti-CD40L mAb). Incubated for 7 days, the cells responsiveness rates were detected by 3 H-TdR methods at the indicated time points, and supernatants were assayed for IFN-?,IL-2,IL-4,IL-10 cytokines levels by commercial ELISA kits. Day 5 MLR-cultured cells were assessed for the expressions of CD4, CD8, CD25, CD69, CD40L and CD45RA with flow cytometry(FCM).Cells proliferation for 5 days and cytokines in secondary MLR were assayed according above-mentioned method.Results:Blockade of the CD40-CD40L pathway by anti-CD40L mAb can induce the hyporesponsiveness to alloantigen in primary and secondary MLR culture. In primary MLR culture, the expressions of CD4 +T and CD8 +T cells and CD4 +CD25 +T, CD4 +CD69 +T, CD4 +CD40L +T, CD8 +CD25 +T and CD8 +CD69 +T cells in anti-CD40L mAb group were lower than that in control group ( P 0.05).The expression of CD4 +CD45RA + T in anti-CD40L mAb-cultured group was higher than that in control group( P

BACKGROUND:Meniscus plasty and prosthesis under an arthroscopy are widely used in treating discoid meniscus or normal meniscus injury.The normal shapes of meniscus are maintained by excising medial partial tears and suturing the lateral partial tearsOBJECTIVE:Injury classification and special features of discoid meniscus and normal meniscus were observed,and corresponding trearing methods were used,to discuss the therapeutic effect of repair.METHODS:Totally 260 cases of meniscus injury in knee ioint were selected from the First Aftiliated Hospital of Xinxiang Medical University from September 2003 to June 2008.They were divided into normal meniscus injury group(n=215),and discoid lateral meniscus injury(n=45).People with complete clinical data before operation and following data,confirmed by arthroscopy were selected.Meniscus injury in 260 cases was examined by arthroscopy,and plasty,or partial excision or incomplete resection or full resection was performed according to the injury types and surgical circumstance.RESULTS AND CONCLUSION:All subjects were followed for half a year to 2 years The knee function was evaluated by the Tenger criterion.Four tear types of Discoid meniscus were as follows:73.3% horizontal,15.5% complex,4.4% radial,and 2.2% longitudinal.Five tear types of normal meniscus were as follows:47.9% longitudinal,28.8%radial,1 1.6%horizontal,6 5% transverse and 5.1% complex.In 215 cases of normal meniscus,there were 165 knees with excellentfunction,35 with good,8 with fair and 7 with poor.The excellent and good rate was 93.0%.In 45 cases of discoid meniscus.there were 25 knees with excellent function,16 with good,3 with fair and 1 with poor.The excellent and good rate was 91.1%.Discoid meniscus is different from normal meniscus in anatomical feature and histological structure,therefore,the arthroscopic surgery for discoid meniscus is also different.The most function of meniscus should be remained and the degeneration of knee ioint should be delayed.Meniscus plasty should be performed in all discoid meniscuses except the patients with severe tear of meniscus.

Objective To study glucose,creatinine,urea nitrogen and serum ET-1 of patients with acute cerebral infarction,and to explore the relationship between neurologic impairment and ET-1 levels.Methods The glucose,creatinine,urea nitrogen and serum ET-1 were retrospectively analyzed in 50 patients with acute cerebral infarction ( ＜ 24 h) and 50 patients with non-neurological diseases.ET-1 determined by 125I radioimmunoassay.Results There were no significant differences in glucose,creatinine and urea nitrogen of acute cerebral infarction ( P ＞ 0.05 ) ; Compared to the control groups,ET-1 levels was significantly higher ( P ＜ 0.01 ),and levels of serum ET-1 in acute cerebral infarction were significantly correlated with their neurological deficits ( P ＜ 0.01 ).Conclusions Levels of serum ET-1 can severd as diagnostic and prognostic indicator of acute cerebral infarction.

Objective To study the effect of oral administration of activated charcoal and mannitol on removing toxicant after acute organophosphorus pesticide poisoning (AOPP). Method A total of 41 patients with severe AOPP were randomly divided into experiment group (activated charcoal used as adsorbent and mannitol used as cathartics, n =21)and control group (without adsorbent and cathartics, n = 20). Patients of both groups received routine treatment for AOPP after admission to hospital. The differences in duration of atropinization, the length of hospitalization and the success rate of treatment were compared between two groups. Results There were significant differences in duration of atropinization, the success rate of treatment and hospitalization time between the two groups. Conclusions The combination of activated charcoal and mannitol is more effective than the conventional gastric lavage on removal of organophosphorus pesticides from G-I tract, shorting the duration of atropinization time and hospital stays, and enhancing the success rate of rescue as well as improving the outcome of patients after organophosphorus pesticide poisoning.
