A total of 267 patients with pressure ulcer were randomly divided into treatment and control groups.All of them underwent traditional debridement.The wounds in treatment group were spreaded with traditional Chinese medicine.According to the results of bacteria culture and drug sensitivity,antimicrobial agents were selected in control group.The observation indices of two groups included pain grade,swelling grade,ulcer area and skin temperature difference.Then the variations of observation indices before and after treatment were examined.In treatment and control groups,the different values of pain grade before and after treatment were 2.1 ± 0.9 and 1.2 ± 0.7,swelling grade 1.3 ± 0.6 and 0.7 ± 0.5,ulcer area 4.7 ± 3.1 and 2.4 ± 2.5 and skin temperature difference 0.12 ± 0.05 and 0.22 ± 0.10 respectively.Treatment group was superior to control group and there was statistical significance (P ＜ 0.05).The effective rates were 95.6％ and 65.4％ and the number of cured patients 86 and 33 cases respectively.And there was statistical significance (P ＜ 0.05).

OBJECTIVETo evaluate the erectile and ejaculatory function of sacral tumor patients after sacral nerve root resection and investigate the relationship of erectile and ejaculatory dysfunction (EED) with the level of sacral nerve injury.

METHODSThis retrospective study included 47 male patients aged 16 to 63 (32.6 +/- 6.8) years treated by sacral tumor resection between January 2008 and August 2013. According to the levels of the sacral nerve roots spared in surgery, the patients were divided into four groups: bilateral S1-S3 (n=16), unilateral S1-S3 (n=21), unilateral S1-S2 (n=6), and unilateral S1 (n=4). The patients were followed up for 12 to 41 (27.2 +/- 10.9) months by questionnaire investigation, clinic review, and telephone calls about their erectile and ejaculatory function at 3, 6 and 12 months after surgery and in August 2013.

RESULTSIn the bilateral S1-S3 group, the incidence rates of EED were 31.25% (5/16), 25% (4/16), and 12.5% (2/16) at 3, 6, and 12 months respectively after surgery, with recovery of erectile and ejaculatory function in August 2013. The incidence rates of EED in the unilateral S1-S3 group were 85.71% (18/21), 71.43% (15/21), 52.38% (11/21), and 42.86% (9/21) at 3, 6 and 12 months and in August 2013, respectively; those in the unilateral S1-S2 group were 100% (6/6), 83.33% (5/6), 83.33% (5/6), and 66.67% (4/6) at the four time points; and those in the unilateral S1 group were all 100% (4/4). No statistically significant differences were found in the incidence rate of EED among the patients of different ages or tumor types (P > 0.05).

CONCLUSIONThe incidence of postoperative EED in male patients treated by sacral tumor resection is closely related to the mode of operation. Sparing the S3 nerve root at least unilaterally in sacral tumor resection is essential for protecting the erectile and ejaculatory function of the patient.

OBJECTIVEThis paper aims to develop a monoclonal antibodies (MAbs)- based ELISA for detecting Chlamydophila pneumoniae (C. pneumoniae) antigens in humans with the variable domains (VD) 2 and 3 of the major outer membrane protein (MOMPVD2-VD3) and to assess its sensitivity and specificity by comparing with a widely used MAb that is able to recognize the elementary bodies of C. pneumoniae.

METHODSMOMPVD2-VD3 were overexpressed in Escherichia coli and purified by affinity chromatography. Mice were immunized with the recombinant antigen, and hybridomas secreting MAbs were screened. Three stable hybridomas clones were selected and named 5D6, 7G3, and 8C9. The MAbs-based ELISA was scrutinized for species-specific recognition with a number of human throat swab samples from Group I (156 patients with typical respiratory illness clinically confirmed before) and Group II (57 healthy donors).

RESULTSIn Group I, 55 positive cases were detected by anti-EB MAb-based ELISA, 51 cases were positive by MAbs 5D6-based ELISA, and 33 and 38 cases were positive by MAb 8C9 and 7G3-based ELISA respectively. Of the 57 samples from Group II "healthy donors", 5 were positive and 52 were negative with both anti-EB and 5D6-based tests, while 2 and 3 positive cases were identified by the other two MAb-based ELISAs respectively.

CONCLUSIONThe novel MOMPVD2-VD3 MAb-based assay may have higher specificity than the anti-EB MAb, which may possibly be used as an alternative tool for the diagnosis of C. pneumoniae infection.

OBJECTIVE To study the methods and curative effects of reconstruction of oropharyngeal defects after resection of tonsillar cancer. METHODS Nineteen patients with tonsillar cancer underwent operation. The choice of surgical procedure was decided on the size of the lesions. The tumor was resected through the hyoid approach and mandibular swing approach. Surgical defects were repaired immediately with tongue flap, temporalis myofascial flap, pectoralis major myocutaneous flap. RESULTS The functions of respiration, chewing, deglutition, and speech were restored satisfied in all patients. Partial necrosis of the pectoralis major myocutaneous flap occurred in one patient, and mild difficulty of open mouth in 3 patients after repaired with temporalis myofascial flap. CONCLUSION Choosing what is optimum from multiple feasible surgical methods is prerequisite for better oropharyngeal function and quality of life in patients with tonsillar cancer.

Objective To introduce the therapeutic measure of preventing the first web contracture after hand crush injury in early stage. Methods Three types were divided according to the traumatic condition in 57 cases: closed injury, open injury and with blood vessel of thumb or fingers injury, and used different method such as closing injury postpone, opening the first web by kischner wire or mini-external fixation splint and covered by local or island flap to cure each type in primary and early stage, after 6 months, measured the width and angle of the first web. Results Forty-one cases were followed-up after 3 months - 2 years,abduction and opposition of the thumbs were fine, the average of width and angle of the first web were (5.89 ± 0.58)cm and (87.85 ± 6.03)°. Conclusion The key points of preventing the first web contracture after crush injury are opening the first web that being covered by local flap and to use splint in primary stage.

OBJECTIVETo evaluate the efficacy and safety of hemocoagulase acutus for injection and determine its curative dose.

METHODSForty-five patients on abdominal surgeries were randomly allocated into 2 study groups and 1 control group. Thirty minutes before the operation, the patients in the study groups received intravenous hemocoagulase acutus at 1 U and 2 U, respectively, and control group had no treatment. The hemostatic time, hemorrhagic volume, and hemoagglutination were observed in all the groups.

RESULTSThe average hemorrhagic volume and hemorrhagic volume per square were significantly lower in the two study groups than in the control group (P<0.05), and the average hemorrhagic volume per square were significantly lower in study group 2 U than in the 1 U group (P<0.05). No significant differences were found in adverse effects between the 3 groups.

CONCLUSIONHemocoagulase acutus for injection has good hemostatic effect for controlling capillary hemorrhage at the abdominal incisions and can be safely used in the surgical patients.

OBJECTIVETo study the protective effect of memantine on the regulation of N-methyl-D-aspartate (NMDA) receptor in dichlorvos-poisoned rat brain, and to understand the mechanism of its role in organophosphate poisoning.

METHODSSD rats were administrated dichlorvos (25 mg/kg, ip) then three groups were treated with memantine at doses of 5, 15 and 45 mg/kg respectively. The activity of acetylcholinesterase (AChE) and binding capacity of NMDA receptor with [(3)H]MK-801 were determined 16 h after dichlorvos injection.

RESULTSThe time of onset of toxic symptoms in 15, 45 mg memantine treated groups [(18.40 +/- 1.14) and (21.40 +/- 1.52) min respectively] was higher than that in dichlorvos alone group [(16.75 +/- 1.62) min]; the intensity of muscle fasciculation (1.60 +/- 1.14 and 0.80 +/- 0.84, respectively) was less than that in control group (2.85 +/- 0.37); the total score of poisoning symptoms (8.80 +/- 1.79 and 9.00 +/- 2.24 respectively) was also less than that in dichlorvos group (14.60 +/- 1.70). The AChE activities both in blood and brain of memantine treated groups were not significantly different from those in dichlorvos alone group. The affinity (Kd value) and density (Bmax value) of brain NMDA receptor in dichlorvos exposed rats [(75.55 +/- 7.87) nmol/L, (0.46 +/- 0.06) pmol/mg pro respectively] were higher and lower respectively than those in control group [(37.37 +/- 4.17) nmol/L, (0.62 +/- 0.04) pmol/mg pro respectively]. Lower level of memantine (5 and 25 mg/kg) could antagonize the dichlorvos-evoked down-regulation of [(3)H]MK-801 binding to NMDA receptor in rat brain [Bmax value: (0.55 +/- 0.07) and (0.64 +/- 0.07) pmol/mg pro; Kd value: (38.68 +/- 4.54) and (32.58 +/- 3.90) nmol/L respectively] while higher dose of memantine (45 mg/kg), the Bmax (0.45 +/- 0.06) pmol/mg pro and Kd (22.88 +/- 4.42) nmol/L of NMDA receptor were significantly decreased (P < 0.01).

CONCLUSIONMemantine in certain dose range could protect against the down-regulation of NMDA receptor in rat brain, and alleviate organophosphorus poisoning symptoms to some extent. The recovery of AChE activity inhibition wasn't involved in the treatment with memantine on dichlorvos poisoning, therefore, atropine and a proper AChE reactivator (an oxime) should be used clinically.
