Objective:To assess whether familial occurrence has an influence on the morphological characteristics of patients with nonsyndromic cleft lip and/or palate (NsCL/P).Methods:A case-control analysis was performed on the morphological characteristics of familial group and sporadic group,using medical records of 1967 patients with NsCL/P treated in the Affiliated Stomatological Hospital of Nanchang University from 2002 to 2014.Results:164 (8.34％) cases presented a positive history of cleft in their families.The cleft types,the positive familial rate of cleft lip only (CLO),cleft lip and alveolar ridge(CLA),cleft lip and palate (CLP) and cleft palate only (CPO) were 8.11％,8.54％,6.19％ and 9.65％ respectively.A positive family history of NsCL/P was associated with 0.66 times risk of CPO (P =0.036,OR =0.66,95％ CI 0.44-0.98) compared to those of CLO,CLA and CLP.In familial group of CLP,the lateral incidence of male patients was different from that of female patients (P ＜ 0.001).There was no significant difference between familial group and sporadic group on birth weights,parental child-bearing age and clinical manifestations of patients.Conclusion:Familial occurrence might have an influence on cleft type,laterality and gender of the patients with NSCL/P.

Background With the widely application of phacoemulsication for cataract,dry eye-associated symptoms,such as foreign body sensation and burning frequently occur after cataract surgery in some patients.Objective This study was to evaluate the repair effects of recombinant human epithelial growth factor (rhEGF) on ocular surface injuriy after phacomulsification. Methods This was a prospective study,and informed consent was obtained from each subject before the experiment.One hundreds and twenty eyes of 89 consecutive patients after phacomulsification for age-related cataract were collected and randomized into rhEGF group,hyaluronic acid group and control group and 40 eyes for each.RhEGF drops and hyaluronic acid drops were topically administered 4 times per day for consecutive 4 weeks after surgery in corresponding group,and no drops mentioned above was used in the control group.The 0.3％ ofloxacin eye ointment and tobramycin+dexamethasone drops were used as the element drops in all patients of each group.Corneal fluorescein staining score,tear film break-up time ( BUT),Schrimer Ⅰ test without topical anesthesia were performed 1 day before surgery and 1 day,1 week,2 weeks and 1 month after surgery.Results The demography and the relevant surface examinational outcomes were no significantly different among the rhEGF group,hyaluronic acid group and control group in preoperation (age:F =3.74; gender:x2 =0.615; corneal fluorescein staining:F =0.247 ; BUT:F =0.579 ; Schrimer Ⅰ test:F =0.475 ; all P＞ 0.05 ).With the prolong of the time,the corneal fluorescein staining scores and Schrimer Ⅰ test values appeared a early ascent and latterly decline,and the BUT value showed a early shorten and latterly restore,with a statistically significant differences among various time points( F时间 =6.754,6.079,6.233,P＜0.01 ).Meanwhile,statistically significant differences were found in the corneal fluorescein staining scores,Schrimer Ⅰ test values and BUT among these 3 groups (F分组 =4.953,4.511,4.071,P＜0.05 ).The corneal fluorescein staining scores in the rhEGF group were significantly lower than those in the hyaluronic acid group at 2 weeks and 1 month after operation(P=0.039,0.014),and the BUT values in the rhEGF group were significantly longer than ones in the hyaluronic acid group at 1 week and 2 weeks after operation (P =0.019,0.007).The Schrimer I test values were significantly reduced in the rhEGF group compared with hyaluronic acid group at 1 week,2 weeks and 1 month after operation (P=0.022,0.003,0.019). Conclusions RhEGF promotes the repair of the ocular surface injury in the patients with age-related cataract after phacomulsification.

OBJECTIVEThis study described the clinical, surgical, and radiographic findings of simple bone cysts.

METHODSA retrospective study was conducted for patients diagnosed with simple bone cysts in the Department of Oral and Maxillofacial Surgery of the Affiliated Stomatological Hospital of Nanchang University from March 2005 to March 2015. Clinical, radio-graphic, surgical, and follow-up data were gathered. Results were statistically analyzed by central tendency and dispersionusing SPSS 20.0 software.

RESULTSEleven cases of simple bone cysts were collected, including three male and eight female patients. Ten cases (90.9%) were asymptomatic and one case developed symptoms of swelling. All of the cases had no history of trauma in the affected area, and all were solitary; ten cases (90.9%) were unilocular, and one (9.1%) was multilocular.The shape of each lesion could be assigned to four categories: cone (3 cases), round (2 cases), oval (4 cases), and irregular (2 cases). The treatment in 10 cases consisted of surgery to explore the cavity and curettage of the bone walls. During surgery,the bone cavity in seven cases (70%) was vacant, whereas serous fluid was found in two cases (20%) and serous-bloody fluid in one case (10%). Of the ten cases, three cases exhibited complete bone healing and seven cases showed new bone formation.

CONCLUSIONSimple bone cysts of the jaws are usually asymptomatic and appear incidentally on routine radiographies. The prevalence is higher in the mandible and young people. The patient usually has no history of trauma, and the bone cavity of lesion is mostly vacant. Curettage of the bone walls of the lesion is suggested for simple bone cysts. Systemic clinical and radiologic follow-up are necessary to ensure successful treatment.

In the 1960s, modern science began involving the essence of heat syndrome, but there have still no in-depth systematic studies on pathological mechanisms of heat syndrome and action mechanisms of cold and cool herbs. In this study, the animal model with heat syndrome was set up by feeding herbs with hot property, and then cold and cool herbs was applied in the experimental therapy. The two-dimensional electrophoresis and mass spectrometry technologies were adopted to compare the liver mitochondria proteome of the rats of the heat syndrome model and the ones treated with cold and cool herbs, so as to discover specificity-related proteins after heat syndrome and treatment with cold and cool herbs.

Objective To observe the protective effect of N-NAC on radiation-induced lung injury. Methods 86 cases of thoracic neoplasm patients were chosen and randomly divided into two groups,group RT +N(n =43)and group RT(n =43).Two groups were observed by CT after radiotherapy.Acute and chronical toxicities were graded by RTOG.TGF-β1,IL-1,IL-4,TNF were observed before and after the radiotherapy.Results After 3 monthsof radiotherapy,RTOG≥2 was 23.4%(RT +N),while RTOG≥2 was 53.1%(RT).there was significant differencebetween the two groups(P <0.01).At 6,9 and 12 months,fibrosis was present in 28.4%,25.4%,22.4% receivingRT vs 58.4%,54.4%,52.4% receiving RT +N,there was significant difference between the two groups(P <0.05).TGF-β1,IL-1,IL-4,TNF were observed which showed that The RT +N were lower than RT.Conclusion N-NAC can reduce incidence rate of lung injury in radiotherapy,and can reduce the content and the release of TGF-β1,IL-1,IL-4,TNF.

OBJECTIVE: To explore the effects of Chinese herbs for replenishing qi and resolving stagnation on hypoxia-inducible factor-1alpha (HIF-1alpha) and vascular endothelial growth factor (VEGF) in granulation tissue of skin ulcers in rats with syndrome of blood stasis and qi deficiency. METHODS: Diabetic rats with back full-thickness skin lesion and syndrome of blood stasis and qi deficiency were divided in to five groups: untreated group, basic fibroblast growth factor (bFGF)-treated group, Yiqi Huayu Recipe (a recipe for replenishing qi and resolving stagnation)-treated group, Yiqi Recipe (a recipe for replenishing qi)-treated group and Huayu Recipe (a recipe for resolving stagnation)-treated group, and another eight normal rats served as normal control group. Immunohistochemical method and image analysis were used to test the expressions of HIF-1alpha and VEGF in granulation tissue of skin ulcers in rats with diabetes. RESULTS: In the untreated group, the expression of HIF-1alpha was significantly increased and the expression of VEGF was significantly decreased as compared with those in the normal control group (P<0.01). The expression of HIF-1alpha was obviously lower (P<0.01) and the expression of VEGF was significantly higher in the four drug treated groups as compared with those in the untreated group. In the Yiqi Huayu Recipe-treated group, the expression of HIF-1alpha was obviously lower than those in the bFGF-treated, Yiqi Recipe-treated and Huayu Recipe-treated groups (P<0.05 or P<0.01), and the expression of VEGF was significantly higher than that in the bFGF-treated group (P<0.01). CONCLUSION: Chinese herbs for replenishing qi and resolving stagnation can promote the wound healing in rats through reducing the expression of HIF-1alpha, accelerating the expression of VEGF in granulation tissue of skin ulcers in rats with diabetes and ameliorating the status of ischemia and hypoxia.

BACKGROUNDTenidap is a liposoluble non-steroidal anti-inflammatory drug that is easily distributed in the central nervous system and also inhibits the production and activity of cyclooxygenase-2 (COX-2) and cytokines in vitro. This study aimed to evaluate the neuroprotective effect of tenidap in a pilocarpine rat model of temporal lobe epilepsy (TLE).

METHODSTenidap was administered daily at 10 mg/kg for 10 days following pilocarpine-induced status epilepticus (SE) in male Wistar rats after which prolonged generalized seizures resulted in TLE. After tenidap treatment, spontaneous recurrent seizures (SRSs) were recorded by video monitoring (for 7 hours per day for 14 days). The frequency and severity of the SRSs were observed. Histological and immunocytochemical analyses were used to evaluate the neuroprotective effect of tenidap and detect COX-2 expression, which may be associated with neuronal death.

RESULTSThere were 46.88 ± 10.70 survival neurons in tenidap-SE group, while there were 27.60 ± 5.18 survival neurons in saline-SE group at -2.4 mm field in the CA3 area. There were 37.75 ± 8.78 survival neurons in tenidap-SE group, while there were 33.40 ± 8.14 survival neurons in saline-SE group at -2.4 mm field in the CA1 area. Tenidap treatment significantly reduced neuronal damage in the CA3 area (P < 0.05) and slightly reduced damage in the CA1 area. Tenidap markedly inhibited COX-2 expression in the hippocampus, especially in the CA3 area.

CONCLUSIONTenidap conferred neuroprotection to the CA3 area in a pilocarpine-induced rat model of TLE by inhibiting COX-2 expression.

OBJECTIVETo summarize our hospital's experience in the diagnosis and treatment of Candida infection in patients with acute necrotizing pancreatitis (ANP).

METHODSSeventy-eight cases with ANP were reviewed. There were diagnoses either by operative finding or by CT scanning. Sixty-two cases received prophylactic antibiotic treatment, other sixteen did not. For cultivation of Candida, blood, urine, stool, sputum and wound drainage fluid culture, and swabs were examined microbiologically for fungi.

RESULTSThe incidence of Candida infection in all patients with ANP was 17.9% (14/78) and mortality was 28.6% (4/14). The incidence of prophylactic antibiotic group was 19.4% (12/62) and mortality was 25.0% (3/12). Non prophylactic group was 12.5% (2/16) and 50.0%.

CONCLUSIONSOur data provide evidence for the clinical significance of Candida infection in patients with ANP. The current prophylactic antibiotic treatment can prevent a septic course of the ANP, but might lead to the evolution of Candida infection.
