Fourty four specimens of maxillary mucosa from 36 patients with chronic maxillary sinusitis were examined in order to observe whether and where immune complexes are deposited in and to assess the quantity of various immunoglobulins (IgG, IgM, IgA) bearing cells with immunofluorescence technique. Erythrocyte immune adherent function and circulating immune complex (CIC) level were also measured in patients with chronic maxillary sinusitis. The results showed that CIC level was increased and erythrocyte immunological function was disturbed, which led to a lot of immune complexes depositing in maxillary mucosa. The results reveal the relationship between chronic sinusitis and type Ⅲ allergic reaction.

Objective To explore the microsurgical technique of ependymoma in conus medullaris and cauda equina. Methods Sixteen patients with ependymoma confirmed by pathology after operation in conus medullaris and cauda equina were analyzed retrospectively for their clinical manifestations, imaging features and microsurgical treatment. Results All patients conducted preoperative MRI, and total tumor resection was achieved in 14 patients and subtotal resection in 2 patients. The pathological examinations confirmed the tumor as myxopapillary ependymomas in 7 patients. Symptoms of fifteen patients were alleviated significantly after operation. One patient had urine retention after operation and was gradually restored 1 week after operation. All patients were followed up for 1-3 months, and there was no case of recurrence. Conclusions Ependymoma in conus medullaris and cauda equina is rare and easily misdiagnosed, with no specific clinical manifestations. MRI should be conducted as soon as possible to identify the diagnosis. Microsurgical treatment is an effective method for ependymoma in conus medullaris and cauda equina.

Objective To sum up the experiences of early diagnosis and surgical treatment of thoraco abdominal injuries. Method The clinical material in 65 cases of thoraco abdominal injuries treated from 1990 to 1998 was retrospectively reviewed. Result Thoracic explorations and closed thoracic drainage and abdominal operations were carried out in 15 cases and in 50 cases respectively. 65 cases were cured and 3 cases (5%) died of large cardiac blood vessel injuries and excessive blood loss. Conclusion The thoraco abdominal injuries are of very critical illness, it′s important to make early dignosis,promt and proper surgical operation.Meanwhile,active antishock measures, postoperative complication prevention, critical care for the patients are also very important for a better prognosis.

Objective To explore the clinical features and prevention measures of neonatal pneumonia complicated with pneumothorax.Methods Clinical data of 26 neonatal pneumonia patients complicated with pneumothorax were retrospectively analyzed.Results In 26 cases of neonatal pneumonia complicated with pneumothorax,16 cases(61.4％) were aspiration pneumonia,10 cases(38.5％) were infectious pneumonia.2 cases of not obvious mild cyanosis and dyspnea were given conservative treatment,24 cases were shortness of breath cyanosis,groan,face pale,difficulty in breathing,restlessness,irritability.Breath sounds were reduced or disappear,sound shift,cyanosis to oxygen can not be sustained remission.Blood oxygen saturation were lower grade.One side or both sides of the chest profile were apparent uplift with thoracic puncture exhaust or thoracic closed drainage.24 cases(92.5％) suffered from pneumothorax were cured.2 cases (7.7％) gave up the treatment,including 1 case died and 1 case loss prevention.Conclusion Pneumonia of newborn pneumothorax is secondary to inhalation of most inappropriate,infection,airway pressure,suction.Once found,timely treatment is important.Mild cyanosis can spontaneous remission,cyanosis having oxygen can not be sustained remission.The prognosis of it by thoracic puncture exhaust or closed thoracic drainage is good.Actively control influence during pregnancy,birth and postpartum.Preventing meconium inhalation can reduce the occurrence of neonatal pneumonia complicated with pneumothorax.

ObjectiveTo analyze the therapeutic experience and value of hemoperfusion in children with acute tetramine poisoning.MethodsAccording to the choice of children's legal guardian,67 cases with acute tetramine poisoning were divided into two groups:the perfusion group (48 cases),and the control group (19 cases).The patients in perfusion group received blood perfusion based on conventional treatment,while the patients in control group received conventional treatment only.Survival outcomes of patients with different serum tetramine concentrations in two groups were compared.ResultsWhen the serum concentration of tetramine was ＞0.5 mg/dl,patients in both groups died in a short time.When the serum concentration of tetramine was 0.20～0.49 mg/dl,the drop value of serum concentration of tetramine significantly greater in perfusion group [(0.28±0.02) mg/dl] than that in control group [(0.13±0.03) mg/dl] (P＜0.05).When the serum concentration of tetramine was ＜0.2 mg/dl,the drop value of serum concentration of tetramine in two groups showed no significant difference [ (0.12±0.02) mg/dl vs (0.11±0.03) mg/dl] (P＞0.05).Conclusion The treatment method for tetramine poisoning should be selected based on the serum concentration of tetramine.

Objective To develop new surgical first aid kits for combat readiness ,and increase the ability of field first aid .Methods On the basis of disposable surgical kits ,the surgical towels were improved .The water absorbing layer was made of SPA materials which inte-grated optimization for surgical use .Results The new surgical first aid kits for combat readiness have the surgical towels with strong water absorption,complete sterile materials,and short time for ready of supplies.Conclusion The new surgical first aid kits for combat readiness have the advantages of small volume ,practicability,available for surgery ,at the same time,which could keep the surgical incision dry and the temperature of patients stability and be helpful to decrease the risk of pressure ulcer and infection ,simplify work procedure .

OBJECTIVE:To observe the clinical efficacy of herbal desensitizer in the treatment of dentine hypersensitivity. METHODS: 126 patients with dentine hypersensitivity were enrolled: 64(a total of 172 diseased teeth) were randomly assigned to trial group to be treated with herbal desensitizer,and 62(158 diseased teeth) to control group to be treated with sodium fluoride glycerin. The clinical effects observation was scheduled immediately,3 and 6 months after the treatment. Then the results were analyzed using statistics software.RESULTS: Significant differences were found between the trial group and the control group in clinical effects (P

The expression of c-erbB-1 and c-erbB-2 oncoproteins were investigated by immunohistochemical technique using monoclonal antibodies to c-erbB-1 and c-erbB-2 oncoproteins in 43 cases of hasal cell carcinoma (BCC) and 26 cases of squamous cell carcinoma (SCC). The results showed that: ① The expression of c-erbB-1 oncoprotein in BCC increased; the expression of c-erbB-2 oncoprotein in BCC reduced significantly, and lost in 16 cases (16/43). ② The intensities of c-erbB-1 and c-erbB-2 oncoprorein expression had negative and positive correlations to the degrees of SCC differentiation respectively. It is suggested that the abnormal expression of c-erbB-1 and c-erbB-2 oncoprotein in BCC and SCC may play a role in the development of skin tumors.

Aim: To report 3 cases of relapsing polychondritis admitted within a month, and to explore the therapeutic programme. Methods: Based on therapeutic effect of traditional immuno suppressant and their side effects, the programme was designed as follows: During acute episode, 60～90mg of tripterygium glucosides and 30～60mg of prednisone were medicated orally every day and 1ml(5mg) of diprospan was injected into the painful cortilaginous areas. After the symptoms subsided, the daily dosages of oral drug were gradually decreased to 30～60mg of tripterygium glucosides and 10～20mg of prednisone for four months' course. Results: All the 3 cases′ symptoms were obviously subsided within a half month. All of them were followed up for 22 months. hyperemia, swelling or pain were not fou and in all suffering areas. One case remained a mild cauliflower ear and another case a mild saddle nose. Conclusions: Otorhinolaryngologists need to improve the capabillity of detecting the relapsing polychondritis, in order to make the diagnosis and treatment as early and correctly as possible. Tripterygium wiifordii and steroid have a good therapeutic effect for relapsing polychondritis.
