Help T cell 1/Help T cell 2 and some cytokines disequilibrium can give a suitable explanation for hypersensitivity and hypogammaglobulinemia in primary nephritic syndrome(PNS) patients. The disturbance of regulatory T cell(Treg cell) and Th17 cell can lead to correlated cytokines derangement, which explained the pathogenesis of PNS from another aspect. Refractory nephrotic syndrome can be effectively treated by rituximab followed the percentage of regulatory T cell increasing, which indicated that Treg may play an important role in pathogenesis of PNS.

Objective To evaluate the diagnostic value of procalcitonin(PCT),C-reactive protein(CRP),prealbumin(PA)and white blood cell (WBC)count measurements in patients with severe pneumonia.Methods The serum samples of 34 patients with severe pneumonia,68 non-severe pneumonia patients and 40 healthy volunteers were collected.Serum concentrations of PCT,CRP, PA and WBC count of all samples were determined.Results The levels of PCT,CRP,PA and WBC in patients with severe pneu-monia were (24.07±34.77)ng/mL,(98.75 ±69.63)mg/L,(105.65 ±68.88)mg/L,(12.64±7.62)×109/L,which were signifi-cantly higher than those in non-severe pneumonia patients and healthy group(P <0.05).According to ROC analysis,the sensitivity, specificity and Youden index of PCT were 64.7%,77.9%,0.426.Conclusion The level of serum PCT could be used as good bio-marker for severe pneumonia.Detection of PCT,CRP and WBC together plays an important role in the diagnosis of severe pneumo-nia.

Objective To observe the histological effect of acellular dermal matrix(ADM)on insufficiency in guide keratinized tissue regeneration. Methods 6 cases of single anterior tooth implantation in the hospital in 2016 were included in the study. 3 cases were treated with immediate tooth extraction and implantation. Bone substitution materials were grafted in the space between the tooth extraction socket and the implants. The keratin-ized tissue dehiscence was covered by double layers of acellular dermal matrix membrane(Heal-All?,ZH-BIO, China),which was fixed to the adjacent soft tissue by suturing. Another 3 cases were routinely treated with delayed implantation of single anterior tooth. All the cases were subject to harvesting of the cover soft tissues of implants with a punch 4 months later. The new grown soft tissues were histologically observed. Results All cases were sur-vived. The new grown keratinized tissues were observed. Conclusion Acellular dermal matrix can guide the aug-mentation of keratinized tissues.

Objective: To observe the relieving cough and reducing sputum effects of total alkaloid in Atalantia buxifolia and evaluate the safety preliminarily.Methods: The relieving cough and reducing sputum effects of total alkaloid in Atalantia buxifolia were studied by the cough model caused by the irritation of ammonia water and the phenol red output of trachea in mice.The acute toxicity test and maximum tolerance test were carried out to evaluate the safety.Results: The total alkaloid in Atalantia buxifolia at low dose could obviously prolong cough incubation period and decrease cough times in mice, and that at high dose could significantly increase the secretion of phenol red in respiratory tract, and compared with those in the blank group, the differences were statistically significant (P<0.05).In the acute toxicity test, no death showed after the administration with maximum tolerance dosage, and the rate of weight growth had no difference between the blank group and the model group (P>0.05).Conclusion: The relieving cough and reducing sputum effects of total alkaloid in Atalantia buxifolia are notable in the cough model caused by the irritation of ammonia water and the phenol red output of trachea in mice.The maximum tolerable dose test shows the total alkaloid in Atalantia buxifolia is safe.

Objective To investigate nutrition status and dyspnea in the patients with chronic obstructive pulmonary disease (COPD) between GOLD Ⅱ and GoLD Ⅲ, and test the evaluative validity of disease status by GOLD classification of COPD. Methods Thirty patients with clinically stable COPD were recruited, including 15 patients of GOLD Ⅱ of COPD and 15 patients of GOLD Ⅲ of COPD. Body mass index (BMI), triceps skin-fold thickness (TSF), serum albumin (Alb), and partial pressure of oxygen in arterial blood (PaO2) were measured in each patient. Dyspnea was assessed by the Borg Scale (BS). Exercise stress test was taken by incremental exercise test. Results BMI was significantly lower in the patients of GOLD Ⅲ than that in the patients of GOLD Ⅱ[(19±5 ) kg/m2 vs (23±3) kg/m2,p < 0.05]. TSF was significantly reduced in the patients of GOLD Ⅲ than that in the patients of GOLD Ⅱ[ (8±3) mm vs(13±5) mm, P < 0.01]. Alia in the patients of GOLD Ⅲ was significantly decreased than that in the patients of GOLD Ⅱ [(32±7) g/L vs (36±6) g/L, P <0.05]. The difference of PaO2 between the patients of GOLD Ⅲ and the patients of GOLD Ⅱ was significant [(72±9) nun Hg (1 mm Hg = 0.133 kPa ) vs (78±8) nun Hg, P < 0.01], and the significant difference of BS was found between the patients of GOLD Ⅲ and the patients of GOLD Ⅱ( 5.0±2.0) grades vs (3.0±1.0) grades, P <0.05 ]. In addition, 12 patients in the patients of GOLD Ⅱ took the exercise stress test and 8 patients were found anaerobic threshold (AT), 5 patients in the patients of GOLD Ⅲ took the exercise stress teat and no AT was found. Conclusions The parameters of BMI, TSF, Alb and PaO2 are significantly reduced in the patients of GOLD Ⅲ than those in the patients of GOLD Ⅱ. In the patients of GOLD Ⅲ, BS is higher than that in the patients of GOLD Ⅱ and AT is difficult to obtain, suggesting more severe in degree of impairment. GOLD classification of COPD reflects the disease stares and prognosis in the patients with COPD, as a valuable parameter in clinical practice.
