Objective To investigate the features of gallbladder carcinoma in two-phase spiral CT, and to analysis the values of two-phase spiral CT for the differential diagnosis between gallbladder carcinoma and chronic cholecystitis. Methods The two-phase spiral CT manifestations of 30 cases of gallbladder carcinoma, proved by surgery and pathology, and 30 cases of chronic cholecystitis were analyzed. Results According to the CT findings, the gallbladder carcinoma was categorized into 3 types: intraluminal mass of gallbladder in 6 out of 30 (20.0%), thickening of the gallbladder wall in 11 (33.7%), and mass replacing the normal gallbladder in 13(43.4%). The most common enhancement patterns of the wall in gallbladder carcinoma were hyperattenuation during the arterial phase, while isoattenuation with the adjacent hepatic parenchyma during the venous phase; or hyperattenuation during both phases. The most common enhancement pattern of the wall in chronic cholecystitis was isoattenuation during both phases, with clear hypoattenuation linear shadow in the gallbladder fossa. Other ancillary features of gallbladder carcinomas included: infiltration of the adjacent parenchyma, local lymphadenopathy and intrahepatic metastasis. Conclusion Two-phase spiral CT scan can identify the features of the gallbladder carcinoma and is helpful for the differential diagnosis of these two different disease entities.

AIM:To investigate how to design personalized cataract surgery programs to achieve surgical correction of preoperative corneal astigmatism with surgical astigmatism under the guidance of corneal topography, improve postoperative visual quality and reduce the cost of treatment.
METHODS: Totally 202 cases ( 226 eyes ) cataract patients were divided into randomized treatment group and individualized treatment group. According to the method and location of the incision, randomized treatment group were divided into 8 groups. Surgical astigmatism after different incision were calculated with the use of preoperative and postoperative corneal astigmatism through vector analysis method. Individualized treatment groups were designed personably for surgical method with reference of every surgically induced astigmatism, the surgical method chooses the type of surgical incision based on close link between preoperative corneal astigmatism and surgically induced astigmatism, and the incision was located in the steep meridian. The postoperative corneal astigmatism of individualized treatment group was observed.
RESULTS: Postoperative corneal astigmatism of individualized treatment group were lower than that of 3.0mm clear corneal tunnel incision in the randomized treatment group, there were statistically significance difference, while with 3. 0mm sclera tunnel incision group there were no statistically significance difference. After 55. 8% of patients with the use of individualized surgical plan could undergo the operation of extracapsular cataract extraction with relatively low cost and rigid intraocular lens implantation, the per capita cost of treatment could be reduced.
CONCLUSION: Personalized cataract surgery programs are designed to achieve surgical correction of preoperative corneal astigmatism under the use of corneal topography, improve postoperative visual quality and reduce the cost of treatment.

OBJECTIVETo investigate the clinical effectiveness of sertraline hydrochloride combined with four-spot caress in the treatment of primary premature ejaculation (PE).

METHODSWe randomly assigned 90 primary PE patients to three groups of equal number. The patients in group A (aged [28.1 ± 5.2] yr and with a disease course of [3.1 ± 1.9] yr) were treated with oral sertraline hydrochloride at 50 mg qd, those in B (aged [27.8 ± 4.1] yr and with a disease course of [3.2 ± 2.0] yr) by four-spot caressing (caressing the tongue, breasts, and vulva prior to intercourse), and those in C (aged [27.1 ± 4.7] yr and with a disease course of [3.1 ± 2.0] yr) by the combination of oral sertraline hydrochloride and four-spot caressing, all for 12 weeks. Before and after 4, 8, and 12 weeks of treatment, we obtained the intravaginal ejaculatory latency time (IELT) and Chinese Index of Sexual Function for Premature Ejaculation-5 (CIPE-5) scores and compared them among the three groups of patients.

RESULTSThe IELT was dramatically prolonged in groups A, B, and C after 4 weeks ([1.08 ± 0.29], [0.93 ± 0.28] and [1.21 ± 0.27] min), 8 weeks ([1.43 ± 0.30], [1.20 ± 0.33] and [1.72 ± 0.42] min) and 12 weeks of treatment ([2.12 ± 0.63], [1.90 ± 0.65] and [2.67 ± 0.82] min) as compared with the baseline ([0.63 ?0.14] , [0.60 ?0.14] and [0.62 ?0.11] min) (P < 0.05), even longer in group C than in A and B (P < 0.05). The CIPE-5 scores were markedly improved in groups A, B and C after 4 weeks ([15.17 ± 1.74], [14.57 ± 1.94] and [15.60 ± 1.63] min), 8 weeks ([17.13 ± 1.63], [16.37 ± 1.97] and [18.00 ± 1.05] min) and 12 weeks of intervention ([18.93 ± 1.57], [18.53 ± 1.67] and [20.00 ± 1.46] min ) as compared with the baseline ([12.57 ± 2.05], [13.20 ± 2.51] and [13.07 ± 2.01] min) (P < 0.05), even higher in group C than in A and B (P < 0.05).

CONCLUSIONSertraline hydrochloride combined with four-spot caressing, with its definite efficacy and rare adverse reactions, deserves wide clinical application in the treatment of primary PE.

OBJECTIVETo investigate the synergistic effect of transforming growth factor-beta1 (TGF-beta1) and platelet-derived growth factor-BB (PDGF-BB) on the expression of integrin beta3, in periodontal membrane of rat orthodontic tooth.

METHODSAn orthodontic tooth movement model was established. Up to 32 experimental rats were randomly divided into four groups according to a random number table. The four groups were injected with 1% PBS, TGF-beta1 (5 ng), PDGF-BB (10 ng), and combined TGF-beta1 (5 ng) and PDGF-BB (10 ng) in the buccal submucosal, respectively. The volume injected in each group was 0.1 mL. The animals were then sacrificed on the 10th day. The left maxillary first molar and periodontal tissue were taken. Different expressions of integrin beta3 were detected in periodontal tissues through immunohistochemistry. Mean optical density (OD) values of the positive fields were examined. The data obtained were analyzed through ANOVA. The data followed normal distribution, and were compared via t-test.

RESULTSCompared with the control groups, the expression of integrin beta3 was higher in the experimental groupin tension sides (P < 0.01). Significant differences in tension sides between the single-injection groups and the combined group were observed (P < 0.01). Compared with the control groups, the expression of integrin beta3 was higher in the experimental group in compression sides (P < 0.05). In addition, there was no significant differences in compression sides between the single-injection groups and the combined group (P > 0.05).

CONCLUSIONIn terms of local regulatory factors, TGF-beta1 combined with PDGF-BB enhance the expression of integrin beta3 in the periodontal membrane and accelerate periodontal remodeling. The synergistic effect of the two growth factors is better than the single growth factor.
