OBJECTIVETo study the Chinese intelligibility of patients with velopharyngeal incompetence (VPI).

METHODS100 patients with VPI and 32 normal students were selected for this study. Of 10 patients, 15 with cleft palate, 21 with congenital velopharyngeal incompetence, 56 with post-palatoplasty VPI and 8 with post-pharyngoplasty VPI. Chinese intelligibility was measured by three speech pathologists and relation between degree of abnormal articulation and Chinese intelligibility were studied.

RESULTSChinese intelligibility of the controls was 99.0% and the patients with VPI were 35.2%. Of the patients, the cleft palate was 19.9%, the congenital velopharyngeal incompetence was 32.8%, the post-palatoplasty VPI was 40.3% and the post-pharyngoplasty VPI was 35.2%. The data showed obvious difference among the controls and sub-types of VPI (P < 0.01).

CONCLUSIONS(1) Chinese intelligibility of VPI accompanied with hypernasality is worse. (2) Of misarticulation of VPI, the cleft palate is the worst, in turn the others are the congenital velopharyngeal incompetence, the post-pharyngoplasty VPI and the post-palatoplasty VPI.

AIM To study the effects of Danggui Buxue Decoction total glycosides combined with Hirudo in the treatment of pulmonary fibrosis in rats and its mechanism.METHODS One hundred and twenty male SD rats were selected,eighteen of which were taken as normal group (normal saline),the remaining 102 rats were used to establish model for pulmonary fibrosis.Seventy-two modeled rats were randomly divided into model group (normal saline),Danggui Buxue Decoction total glycosides group (13 mg/kg),Hirudo group (Hirudo powder,4 g/kg) and combination group (Danggui Buxue Decoction total glycosides,13 mg/kg;Hirudo powder,4 g/kg),eighteen rats in each group with intragastric administration.RESULTS On the 7th,14th and 28th days after modeling,alveolar inflammatory score,pulmonary fibrosis degree score,TGF-β1 and PAI-1 expression levels in lung tissue,IL-4 and IL-17 expression levels in alveolar lavage fluid,hydroxyproline (HYP) content in lung tissue in the model group were significantly higher than those in the normal group (P ＜ 0.05).Alveolar inflammatory score,pulmonary fibrosis degree score,TGF-β1,PAI-1,IL-4,IL-17 expression levels and HYP content in the Danggui Buxue Decoction total glycosides group,Hirudo group and combination group were significantly lower than those in the model group (P ＜ 0.05).In the combination group,alveolar inflammatory score,pulmonary fibrosis degree score,TGF-β1,PAI-1,IL-4,IL-17 expression levels and HYP content were significantly lower than those in the Danggui Buxue Decoction total glycosides group and Hirudo group (P ＜ 0.05).CONCLUSION Danggui Buxue Decoction total glycosides combined with Hirudo have good therapeutic effects on pulmonary fibrosis in rats mainly by reducing TGF-β1,PAI-1 expression levels and HYP coment in lung tissue.

OBJECTIVETo investigate the effects of Bushen Huoxue Fang (BSHX) on the apoptosis of epithelial cells in the prostatic ductal system of rats with benign prostatic hyperplasia (BPH) and its possible action mechanism.

METHODSOne hundred 3- month-old male Wistar rats were randomly divided into four groups of equal number (control, castrated, BPH model, and BSHX). BPH models were made by subcutaneous injection of testosterone following castration; the rats in the BSHX group were treated intragastrically with BSHX at 2.34 g/ml after modeling, while those in the other two groups with equal volume of saline, all for 37 days. On the 38th day, all the rats were sacrificed and their prostates harvested for detection of the distribution of TGF-beta1 and alpha-actin and the count of positive cells in the prostatic ductal system by immunohistochemical staining. The apoptosis rate of epithelial cells in the prostatic ductal system was determined by TUNEL assay.

RESULTSThe expression of TGF-beta1 was significantly increased in the rats of the BSHX group as compared with the BPH models in both the proximal prostatic duct ([15.28 +/- 4.30]% vs [36.42 +/- 8.10]%, P < 0.01) and the distal prostatic duct ([4.42 +/- 2.07]% vs [8.71 +/- 2.28 ]%, P < 0.05), while the expression of alpha-actin in the proximal duct was remarkably higher in the BSHX-treated rats than in the models ([28.14 +/- 7.43]% vs [18.28 +/- 4.07]%, P < 0.01), but lower than in the control animals ([33.57 +/- 6.85]%, P < 0.05). Compared with the control group, the BPH models and BSHX-treated rats both exhibited markedly decreased apoptosis of epithelial cells in the proximal prostatic duct ([39.42 +/- 9.20]% vs [3.86 +/- 1.34]%, P < 0.01, and [31.14 +/- 5.64]%, P < 0.01) and distal prostatic duct ([17.60 +/- 4.86]% vs [3.07 +/- 1.14]%, P < 0.01, and [12.37 +/- 2.25]%, P < 0.05). The apoptosis rate of epithelial cells in the prostatic ductal system was significantly higher in the BSHX-treated rats than in the BPH models (P < 0.01).

CONCLUSIONBy upregulating the expression of TGF-beta, BSHX can suppress the reduction of smooth muscle cells in the proximal prostatic duct, promote the apoptosis of prostatic epithelial cells, and thus effectively inhibit benign prostatic hyperplasia.

OBJECTIVETo investigate the effects of Xiezhuo Chubi Decoction (XZCBD) on the microRNA expression patterns of kidney in mice with hyperuricemia.

METHODSSixty Kunming male mice were randomly divided into the high-, medium-, and low-dose XZCBD groups, benzbromarone group, model group, and control group. Except the control group, all mice were established with yeast method combined with uricase inhibition method to build hyperuricemia model, and the corresponding drugs (37.5 g/kg, 18.75 g/kg, 9.375 g/kg, and 0.02 g/kg per day) were administrated on the 7th day. On the 22nd day, the blood uric acid concentration was detected, and microRNA with obvious changes in kidney was screened with qRT-PCR.

RESULTSThe uric acid in the model group was higher than that in the control group, and the levels of the uric acid were reduced after being treated with XZCBD; the differences among groups were significant (P<0.05). Compared with the control group, 32 kinds of microRNA expression changes were detected on the 15th day after being treated with high-dose XZCBD by microRNA expression profile screening. Among them, miR-34a could inhibit the expression of human urate anion exthanger 1, and miR-146a might have inhibited the inflammatory reaction.

CONCLUSIONXZCBD could significantly reduce the serum uric acid level; its effect on hyperuricemia might be through affecting microRNA expressions.

OBJECTIVETo explore the risk factors of acute lymphoblastic leukemia (ALL) recurrence in adult patients and establish a prognosis index (PI) calculation model in order to improve the prevention strategy of ALL in adults.

METHODS104 adult ALL patients from Blood Diseases Hospital & Chinese Academy of Medical Sciences between August 2008 and November 2011 were enrolled. COX proportional hazards regression stratified by Dummy variable was used to set up the prediction model; Kaplan-Meier method and Log-rank test were used to estimate and compare the survival. After calculated individual PI value, patients' expected survival should be estimated by groups.

RESULTSThe overall median survival of adult ALL patients was 22.00 months (95% CI 17.00-27.00). COX regression analysis showed that chemotherapy group patients had a higher risk of recurrence than of ASCT group while setting treatment as the dummy variable (RR=2.052, 95%CI 0.877-4.799, P=0.007). Stratified Analysis showed that the risk factors of B-ALL recurrence in adult patients included HGB <100 g/L (RR=0.186, 95% CI 0.068-0.512, P=0.001), CNSL (RR=7.767,95% CI 2.951- 20.433, P=0.001), number of consolidation chemotherapy<3 (RR=0.445, 95% CI 0.211-0.940, P=0.034) and Ph chromosome positive (RR=2.771, 95% CI 1.353-5.674, P=0.005). Grouped by the PI value, the expected survival of each individual patient could be estimated as PI=0.58 base.

CONCLUSIONHGB, CNSL, number of consolidation chemotherapy and Ph chromosome were independent risk factors of B-ALL recurrence in adult patients. PI value could predict the survival of adult ALL patients and provide reference for individual therapy and prognostic evaluation.

BACKGROUND: Hemorrhoids are one of the most common conditions that lead to surgery, and until now surgical hemorrhoidectomy has been the major effective treatment. Post-operative pain from hemorrhoidectomy has been experienced by thousands of patients and remains a major inconvenience of the operation. OBJECTIVE: This study evaluates the clinical efficacy of the pestle needle therapy, an acupoint stimulation method, for relief of post-hemorrhoidectomy pain. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This was a single-center, patient-assessor-blinded and randomized controlled trial with 154 patients receiving Milligan hemorrhoidectomy surgery. Eligible patients were randomly assigned to either a treatment group or a control group at a ratio of 1:1. The treatment group received the pestle needle therapy, with manual stimulation at Yaoshu (DU2), Mingmen (DU4), Changqiang (DU1), Chengshan (BL57), Erbai (EX-UE2) and the perianal points (1, 3, 5, 7, 9, and 11o'clock around the lesion); while the control group received a sham treatment with very light pressure. Three sessions of treatment were performed at 30 min, 4 h and 12 h after the surgery, and each lasted for 15 min. MAIN OUTCOME MEASURES: The primary outcome was post-operative pain measured with the visual analogue scale (VAS) at 12 h after surgery. The secondary outcomes included the VAS scores measured at 0.5, 2, 4, 6, 8, 24 and 48 h after surgery, the analgesic dose, the time and the VAS score of the patients' first defecation after surgery, as well as the Hamilton Rating Scale for Anxiety (HAMA) evaluated before discharge. RESULTS: The mean pain score of the treatment group was significantly lower than that of the control group (3.10 ± 1.27 vs 4.82 ± 1.29; P < 0.001) at 12 h after surgery. Compared with the control group, patients in the treatment group needed a smaller dose of analgesic within the first 24 hours after surgery (P = 0.002); and their HAMA scores before discharge were lower (4.07 ± 2.40 vs 5.10 ± 2.45, P = 0.009). Compared to the treatment group, patients in the control group had a greater time to the first defecation after surgery ([52.34 ± 15.72] h vs [27.08 ± 13.68] h; P < 0.001), but there was no difference in their VAS scores at the first defecation (P = 0.092). CONCLUSION The pestle needle therapy was effective for relieving pain, reducing anxiety and improving bowel function after hemorrhoidectomy, and it is worthy of clinical application.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.
