OBJECTIVETo observe the effect and safety of plastering Chinese Compound Shenhuang Ointment (CSO) at Shenque (RN8) in promoting the rehabilitation of postoperative gastrointestinal dysfunction patients of qi stagnation blood stasis syndrome (QSBSS).

METHODSA prospective, multi-centered, randomized, double-blinded, controlled trial was conducted in 220 postoperative gastrointestinal dysfunction patients of QSBSS. They were randomly assigned to two groups, the CSO group (110 cases) and the placebo group (110 cases). CSO was plastered at Shenque (RN8) for 5 days after operation. The time of exhaustion, defecation, the recovery of intestinal peristalsis, integrals of TCM syndrome, and serum levels of motilin (MOT)and somatostatin (SS) were observed.

RESULTSCompared with the placebo group, the condition of exhaustion and defecation, the recovery of intestinal peristalsis on the 3rd day after operation was all improved (P < 0.05). The integrals of TCM syndrome at day 2, 3, and 4 were more significantly lowered in the CSO group than in the placebo group (P < 0.01, P < 0.05). The total effective rate of TCM syndrome was 95.3% in the CSO group, better than that in the placebo group (91.8%, P < 0.05). Compared with the placebo group, the serum MOT level increased and the serum SS level decreased at day 5 after operation in the CSO group (P < 0.05).

CONCLUSIONSThe plastering of CSO at Shenque (RN8) could advance the time of exhaustion and defecation, and improve patients' clinical symptoms. And patients could tolerate well.

Objective: To investigate the effect of rhubarb on gastrointestinal blood perfusion in critical illness and hemorrhagic shocked rats.Methods: Clinical Study: Sixty-four septic patients, who suffered from stress ulcer, were treated with rhubarb at a dose of 25 mg/kg. Twenty-five non-septic patients were taken as control. The gastrointestinal perfusion was evaluated by intramural pH (pHi). Animal study: SD rats were anesthetized with intraperitoneal sodium pentobarbital at a dose of 20 mg/kg. Blood-letting were performed in the animals. Blood pressure reduced to 5.32 kPa and maintained for 120 mins. They were resuscitated at the end of shock by reinfusing all of the shed blood. The rats were randomly divided into four groups: Normal control, shock group, therapeutic group (shocked rats were treated with 50 mg/kg rhubarb at the end of shock) and rhubarb group (normal rats were treated with rhubarb). Laser Doppler was applied to estimate the gastrointestinal blood perfusion. Results: Clinical Study: The gastrointestinal pHi in septic patients was much lower than that in the control, whereas rhubarb could obviously elevate gastrointestinal pHi (P<0.001). In addition, rhubarb also had good effect on gastric hemorrhage caused by stress ulcer. Animal Study: Although the shocked rats were resuscitated completely, their gastrointestinal blood perfusion was much lower than that in the control. Rhubarb could significantly improve the blood perfusion in gastrointestinal mucosa and mesentery (P<0.01). Furthermore, rhubarb also increase the gastrointestinal perfusion in normal rats. Conclusion: Rhubarb could improve gastrointestinal blood perfusion in critical illness and shocked rats.

OBJECTIVETo explore the technique and clinical results of close reduction by manipulation and minimally invasive percutaneous osteosynthesis with intramedullary nail for the treatment of femur shaft fractures. methods: A retrospective study was conducted to analyze 96 patients with the femur shaft fractures who had been treated with close reduction by manipulation and minimally invasive percutaneous osteosynthesis with intramedullary nail. There were 67 males and 29 females. The average age of patients was 39 years old (ranging from 16 to 88). According to AO fracture classification for the femur shaft fractures,there were 29 cases of type A,46 type B,21 type C.

RESULTSAll the patients were followed up and the duration ranged from 12 to 24 months (averaged, 15 months). All the fractures showed union. The time required for the bony union ranged from 3 to 10 months (averaged,4 months). The clinical results were evaluated by Thorsen classification system. At the latest follow-up, 87 patients obtained excellent results, 7 good, 2 fair.

CONCLUSIONThis treatment method combines advantages of intramedullary nail with close manipulative reduction, so can get satisfactory clinical results for the treatment of femoral shaft fracture with minimal trauma.

Objective To analyze the clinical speciality of invasive fungal infection(IFI)and provide doctors with clinical evidence for early anti-fungal therapy.Method One hundred and thirty-seven patients with 91 male and 46 female,who suffered from invasive fungal infection in ICU from January.1,2000 to June 30, 2006,were enrolled in this study.The age ranged from 17 to 82 years old.Out of 137 patients with IFI,the percentage of albicans candida,glabirate candida,tropicalis candida and parapsilosis candida were 47.4%, 26.3%,20.4% and 3.6%,reseparately.The sputum,urine,blood and other drainages were collected to perform the fungal examination after three days of admission every three days.Results Of 137 patients,42 of them were complicated with hemorrhage,53 patients with IFI developed candida anthema in the chest,abdomen and extremity.,49 patients suffering from IFI had organ dysfunction.The chest image revealed that infiltration caused by IFI especially occurred in apex of lung in some patients.The pathogen analysis displayed that albicans candidiasis easily developed candida anthema,glabirate candidiasis frequently resulted in organ dysfunction,and tropicalis candida led to hemorrhage in some organs.Conclusions The clinical specialty,of IFI caused by candida included hemorrhage,candida anthema,organ dysfunction,and infiltration in apex of lung.

OBJECTIVETo analyze the epidemiological characteristics of pediatric burn in the midwest region of Inner Mongolia and the related areas, and to provide reference for seeking pertinent measures of prevention and treatment.

METHODSMedical records of patients hospitalized in the 253rd Hospital of PLA, the 322nd Hospital of PLA, and the Inner Mongolia Autonomous Region Hospital from January 1996 to December 2010 were collected. Patients were divided into pediatric burn group with specific reason (group SF, with scald resulted from construction defect of Guo-lian-kang--a heatable brick bed linked to a cooking pot), and burn control group with other causes (group C) according to the main injury cause. Clinical data of patients in both groups, including general condition, family background, occurrence regularity, and outcome, were analyzed. The epidemiological trend of variation before and after taking preventive measures (1996 to 2001 and 2002 to 2010) was compared. Data were processed with chi-square test and rank sum test.

RESULTS(1) General condition: out of 16 595 pediatric burn patients, 15 816 cases (95.3%) suffered scald due to liquids with high temperature, and 779 cases (4.7%) suffered burns due to other causes. Patients in group SF (scald due to specific cause--Guo-lian-kang) accounted for 32.2% (5089/15 816) of the total suffered scald by liquids with high temperature, and 30.7% (5089/16 595) of all the inpatients the cause of burn was related to Guo-lian-kang (group SF). The patients in group SF admitted to the 322nd Hospital of PLA accounted for 34.2% of all the inpatients admitted to this hospital (1803/5267), more than the other two hospitals in this study. The number of patients in group C was 11 506, accounted for 69.3% of all the inpatients. The age of patients ranged from 8 months to 5 years in group SF and 1 month to 12 years in group C. The age of the majority of patients ranged from 1 to 3 years in both groups. The ratio of male to female was 2.1:1.0 in group SF and 1.4:1.0 in group C. The incidence of scald involving multiple body parts in group SF (3590 cases accounting for 70.5%) was obviously higher than that of group C (6311 cases accounting for 54.8%, χ(2) = 361.138, P < 0.01). In both group SF and group C, the incidence in different sites was ranked from high to low as follows: upper limbs, lower limbs, the head-face-neck region, and the trunk. The degree of injury in group SF was much more severe than that of group C (Z = 27.770, P < 0.01). The rate of patients without pre-hospital treatment was 31.2% (1588/5089) in group SF, which was obviously higher than that of group C (24.8%, 2857/11 506, χ(2) = 73.010, P < 0.01). The rate of patients treated with cryotherapy was obviously lower in group SF (14.7%, 747/5089) than in group C (19.6%, 2255/11 506, χ(2) = 57.636, P < 0.01). The rate of patients treated with delayed resuscitation (6 hours after injury) in group SF (31.5%, 1601/5089) was obviously higher than that of group C (7.8%, 897/11 506, χ(2) = 1545.234, P < 0.01). (2) Family background and occurrence regularity: in group SF, 67.3% (3424/5089) of the patients came from farming area, 22.1% (1123/5089) from villages and towns, and 10.7% (542/5089) from urban areas. In group C, 32.4% (3727/11 506) of the patients came from farming area, 48.4% (5570/11 506) from villages and towns, and 19.2% (2209/11 506) from urban areas. Most of the patients in group SF (77.8%, 3958/5089) were injured between October and March, while most of the patients in group C (58.2%, 6697/11 506) were injured between May and October. (3) Outcome and epidemiological variation: the cure rate of patients in group SF was 32.3% (1645/5089), which was obviously lower than that of group C (44.7%, 5143/11 506, χ(2) = 215.615, P < 0.01). The mortality of patients in group SF was 1.6% (79/5089), and it was obviously higher than that of group C (0.4%, 46/11 506, χ(2) = 62.700, P < 0.01). From 1996 to 2001, patients in group SF accounted for 42.5% (2213/5212), while patients in group C accounted for 57.5% (2999/5212) of the inpatients scalded by hot liquid. After taking preventive measures against injury due to Guo-lian-kang, incidence of scald injury in group SF was lowered to 27.1% (2876/10 604), while the incidence in group C remained at 72.9% (7728/10 604) of the inpatients with hot liquid scald from 2002 to 2010. The difference between the two periods was statistically significant (χ(2) = 376.695,P < 0.01).

CONCLUSIONSThe defect of construction of Guo-lian-kang is one of the main factors that lead to a high incidence of pediatric burn in the midwest of Inner Mongolia. Installation of a protective bannister between the cooking pot and the "kang (heatable brick bed)" can obviously reduce the incidence of scald injury. Special injury-causing factors, unprofessional pre-hospital treatment of the wound, delayed resuscitation after shock are the main causes of increasing mortality and disability, and they constitute the key targets of prevention and treatment of such injury in future.

OBJECTIVETo investigate the expression of the augmenter of liver regeneration (ALR) in cryptorchidism spermatogenic cells.

METHODSTwenty cryptorchidism rat models were established by surgery, 10 included as normal controls and anther 10 as sham-surgery controls. The expression of ALR was detected by immunochemistry, the COX II level measured by immunofluorescence and the ferric iron contents assayed by Perls stain.

RESULTSALR expressed intensively in the spermatogonia of the control groups but in a signigicantly diminished manner in the cryptorchidism group. No significant difference was found in the COX II level between any two groups of the same age. Ferric iron content of the PND30 cryptorchids decreased significantly (P < 0.05).

CONCLUSIONALR may play an important role in early spermatogenesis. Metabolism dysfunctions caused by ALR defection might be a crucial mechanism for aspermatogenesis of cryptorchidism.

OBJECTIVETo study the therapeutic effects of azithromycin in treatment of congenital toxoplasmosis in children.

METHODSDefinite diagnosis of congenital toxoplasmosis was made on the basis of clinical manifestation combined with one or more positive results of the following laboratory tests and excluded other congenital infectious diseases: toxoplasma DNA (TOX-DNA), circulating toxoplasma antigen (TOX-CAG), and toxoplasma IgM antibody (TOX-IgM). All the patients were given oral azithromycin 10 mg/(kg.d) for 6 days followed by 8 days without medication (one course of treatment), and the regimen was persisted for 2 months and then another 2-month treatment was given at a 1-month interval. The authors continued to provide further treatment according to the state of the illness at one month interval. The patients received 2 to 8 (average 5) courses of treatment. The patients were followed-up for 2.5 to 5 (average 4) years.

RESULTSThe treatment was effective in all the patients and the patient's condition was improved. The authors repeated in 12 cases the four tests for toxoplasma (TOX-DNA, TOX-CAG, TOX-IgM, and TOX-IgG) 9 months to one and a half years after treatment. In 10 cases all these tests showed negative results, in 2 cases TOX-IgG was positive and in the other 4 cases symptoms disappeared.

CONCLUSIONThe results of the study showed that oral azithromycin had significant therapeutic effects with little side effect and was well tolerated. Azithromycin may become an alternative therapy in treatment of congenital Toxoplasma gondii infection in children.

BACKGROUNDCytosine deaminase (CD) converts 5-fluorocytosine (5-FC) to 5-fluorouracil (5-FU) in CD/5-FC gene therapy, 5-FU will be mostly converted into nontoxic beta-alanine without uracil phosphoribosyltransferase (UPRT). UPRT catalyzes the conversion of 5-FU to 5-fluorouridine monophosphate, which directly kills CD::UPRT-expressing cells and surrounding cells via the bystander effect. But the pharmacokinetics and the bystander effect of CD::UPRT/5-FC has not been verified in vivo and in vitro. Before the CD::UPRT/5-FC bi-gene therapy system is used in clinical trial, it is essential to monitor the transgene expression and function in vivo. Thus, we developed a preclinical tumor model to investigate the feasibility of using (19)F-magnetic resonance spectroscopy ((19)F-MRS) and optical imaging to measure non-invasive CD and UPRT expression and its bystander effect.

METHODSC6 and C6-CD::UPRT cells were cultured with 5-FC. The medium, cells and their mixture were analyzed by (19)F-MRS. Rats with intracranial xenografted encephalic C6-CD::UPRT glioma were injected intraperitoneally with 5-FC and their (19)F-MRS spectra recorded. Then the pharmacokinetics of 5-FC was proved. Mixtures of C6 and C6-CD::UPRT cells at different ratios were cultured with 5-FC and the cytotoxic efficacy and survival rate of cells recorded. To determine the mechanism of the bystander effect, the culture media from cell comprising 25% and 75% C6-CD::UPRT cells were examined by (19)F-MRS. A comparative study of mean was performed using analysis of variance (ANOVA).

RESULTS(19)F-MRS on samples from C6-CD::UPRT cells cultured with 5-FC showed three broad resonance signals corresponding to 5-FC, 5-FU and fluorinated nucleotides (F-Nuctd). For the C6 mixture, only the 5-FC peak was detected. In vivo serial (19)F-MRS spectra showed a strong 5-FC peak and a weak 5-FU peak at 20 minutes after 5-FC injection. The 5-FU concentration reached a maximum at about 50 minutes. The F-Nuctd signal appeared after about 1 hour, reached a maximum at around 160 minutes, and was detectable for several hours. At a 10% ratio of C6-CD::UPRT cells, the survival rate was (79.55 +/- 0.88)% (P < 0.01). As the C6-CD::UPRT ratio increased, the survival rate of the cells decreased. (19)F-MRS showed that the signals for 5-FU and F-Nuctd in the culture medium increased as the ratio of C6-CD::UPRT in the mixture increased.

CONCLUSIONS(19)F-MRS studies indicated that C6-CD::UPRT cells could effectively express CD and UPRT enzymes. The CD::UPRT/5-FC system showed an obvious bystander effect. This study demonstrated that CD::UPRT/5-FC gene therapy is suitable for 5-FC to F-Nuctd metabolism; and (19)F-MRS can monitor transferred CD::UPRT gene expression and catalysis of substrates noninvasively, dynamically and quantitatively.
