OBJECTIVETo assess the effectiveness of Tongjiang Granule (TJG) in treating non-erosive reflux disease (NERD) of Gan-Wei incoordination syndrome (GWIS).
METHODSTotally 128 NERD patients of GWIS were recruited from outpatients or inpatients at Department of Digestive Disease, Xiyuan Hospital, China Academy of Chinese Medical Sciences from February 2009 to November 2010. They were randomly assigned to two groups using the block group in the ratio of 1:1, 64 cases in each group. Patients in the experiment group were treated with TJG, 10 g each time, three times a day, while those in the control group were treated with Omeprazole Tablet, 20 mg each time, two times a day. The treatment course of both groups was 4 weeks. The symptoms questionnaires and SF-36 quality of life scale were observed.
RESULTSFinally 114 patients completed the trial. There was statistical difference in epigastric upset, pharyngeal foreign body sensation, abdominal swelling or abdominal pain, and integral of excrement between the two groups before treatment (P < 0.05). However, there was no statistical difference in the rest indices between the two groups (P > 0.05). Compared with before treatment in the same group, the scores of each symptom or the total symptoms were somewhat improved in the two groups (P < 0.01, P < 0.05). There was statistical difference in the rest scores (P > 0.05) except the score of mental health in the experiment group (P < 0.01, P < 0.05). There was statistical difference in the rest scores (P > 0.05) except the score of physical function in the control group (P < 0.01, P < 0.05). There was statistical difference in post-treatment acid reflux, irritability, depression, body pain, roles of emotions (P < 0.01, P < 0.05). The total effective rate was higher in the experimental group, showing no statistical difference when compared with that of the control group (P > 0.05).
CONCLUSIONSTJG had confirmative efficacy in treating NERD patients of GWIS. Meanwhile, it could improve their quality of life, with no obvious adverse reaction.

Background/Aims:
Achalasia is a rare disease, but the incidence is increasing recently. Peroral esophageal myotomy (POEM) is an effective treatment.Regurgitation is a common symptom before and after POEM. Our aim is to investigate the factors related to preoperative and postoperative reflux symptoms.
Methods:
Our study was retrospective. The achalasia patients diagnosed by high-resolution manometry and gastroscopy were divided into reflux group and non-reflux group before and after POEM, respectively. General information, symptoms, POEM information, and manometric results were compared.
Results:
(1) Ninety-six of 130 patients had reflux symptoms before POEM. The lower esophageal sphincter pressure (LESP) in the reflux group was significantly higher than the non-reflux group (P = 0.023), while integrated relaxation pressure (IRP) was similar. The reflux group had longer esophagus than the non-reflux group (P = 0.006). Reflux symptoms were not related to subtypes of achalasia.(2) Twenty-five of 84 patients had reflux symptoms after POEM. Postoperative Eckardt scores, LESP, and 4-second IRP (4sIRP) were significantly lower than the preoperative values (P < 0.001). The preoperative values and POEM information were similar between the postoperative 2 groups and there was no significant difference in the presence of preoperative reflux symptoms between 2 groups.The postoperative LESP and 4sIRP were similar between the 2 groups, however, the postoperative UESP was significantly higher in the reflux group than the non-reflux group (P = 0.042). The non-reflux group had more declines in Eckardt scores and LESP than the reflux group.
Conclusions
The reflux symptoms of achalasia patients without treatment were mainly due to food retention. The postoperative reflux symptoms were not the sign of the excessive relaxation of lower esophageal sphincter.

Objective:To observe the efficacy and safety of ultra photon intense pulsed light combined with hydroquinone cream for the treatment of chloasma.Methods:From January 2020 to October 2022, a total of 30 patients with chloasma treated in the Department of Dermatology, Huazhong University of Science and Technology Union Shenzhen Hospital, ranged from 28 to 54 years old with an average age of 39 years, were randomly divided into three groups with 10 patients in each group: combined treatment group was treated with ultra photon intense pulsed light combined with hydroquinone cream; ultra photon intense pulsed light group was treated with ultra photon intense pulsed light alone; hydroquinone group was treated with hydroquinone cream alone. The efficacy and safety of the three groups were compared after four months of treatment.Results:After the treatment, 10 cases were effective in the combined treatment group, 5 cases were effective in the ultra photon intense pulsed light group and 2 cases were effective in the hydroquinone group. The total effective rate of the combined treatment group was significantly better than that of the ultra photon intense pulsed light group and the hydroquinone group, with statistical significance ( P<0.05). The average melasma area severity index score of the three groups after treatment was significantly decreased compared with that before treatment respectively ( P<0.05), and the average melasma area severity index score of the combined treatment group after treatment was significantly lower than that of hydroquinone group, with statistical significance ( P<0.05). No serious adverse reactions were observed in all the patients. Conclusions:Ultra photon intense pulsed light and hydroquinone cream can improve chloasma alone, but ultra photon intense pulsed light combined with hydroquinone cream has better therapeutic effect.

Iron is an essential element for cell growing including tumor cells. This study was purposed to explore the effect of desferrioxamine (DFO) on cell line K562/A02 and its mechanism. K562/A02 cells were cultured with different concentrations of DFO. The inhibitory effects of adriamycin (ADM) used alone or combined with DFO on the proliferation of K562/A02 was evaluated by MTT assay. The apoptosis rate of K562/A02 cells after treatment with 0, 12.5, 25 and 50 µmol/L DFO alone or in combination with 1 mg/L ADM were analyzed by flow cytometry. ADM accumulation in K562/A02 cells after treatment with different concentrations of 0, 12.5, 25 and 50 µmol/L DFO were also analyzed by flow cytometry. The levels of BAX/BCL-2 and MDR1 mRNA were determined by RT-PCR, and then the protein level of P-glycoprotein (P-gp) was detected by Western blot. The results showed that the IC(50) of ADM for K562 and K562/A02 cells were (1.46 ± 0.07) mg/L and (40.98 ± 3.05) mg/L respectively. The resistance of K562/A02 cells to ADM was 28.06 times as that of K562 cells. After treatment of K562/A02 cell with DFO of 12.5, 25 and 50 µmol/L for 48 hours, the resistance of K562/A02 cells to ADM were increased by 24.95, 16.11 and 9.99 times respectively. When K562/A02 cells were incubated with different concentrations of DFO of 12.5, 25, 50 µmol/L for 48 hours, the apoptosis rat were (3.50 ± 0.30)%, (7.27 ± 0.32)% and (12.53 ± 1.21)% respectively. After co-culture with DFO and ADM for 48 hours, apoptosis rate were (6.13 ± 0.29)%, (9.57 ± 0.40)% and (18.97 ± 1.10)% respectively. The above apoptosis rates was much higher than that of control group (p < 0.05) and they were dose-dependent. In comparison between DFO + ADM group and DFO group, there was no significant difference (p > 0.05). Expression rate of BAX/BCL-2 increased. The levels of MDR1 mRNA reduced. Furthermore, expression of P-gp also decreased in K562/A02 cells. It is concluded that iron increase can promote K562/A02 cells growth and inhibit their apoptosis. Otherwise, iron-deprivation can induce K562/A02 cells apoptosis. DFO disturbs the iron metabolism and inhibits DNA synthesis of K562/A02 cells. This action of DFO may enhance the susceptibility of K562/A02 cells to apoptosis induced by chemotherapeutic drugs. The iron-deprivation may play a role in the treatment of leukemia with combination of DFO with other anticancer agents.

Objective To identify the presence of candidate pathogenicity island 89K DNA sequence of Streptococcus suis serotype 2 (SS2) strains isolated from patient in Zhejiang province. Methods Genes and DNA fragments were amplified by PCR, using specific primers, and three amplified fragments of the89K sequence were directly sequenced. The results were analyzed using software related to bioinformaties and epidemiology. Results 8 strains of SS2 all contained 89K sequence, cps2J and mrp virulent genes, and species-specific 16S rDNA. 3 amplified fragments of 89K candidate pathogenicity island of SS2 ZJ0501 were above 99% similar to SS2 strain identified from outbreaks in Jiangsu in 1998, and the gene fragment of coding DNA recombinant protein in the 89K sequence was highly homological with that of S. dysgalactiae and S. agalactiae. Conclusion In recent years SS2 strains isolaed from patients with clinical symptoms in Zhejiang province had been detected to have contained candidate pathogenicy 89K DNA fragment.

Objective To investigate the regulating effect of fire needling on Wnt andβ-catenin genes of Wnt/β-catenin pathway in neural stem cells in spinal cord injury.Methods Sixty female SD rats were randomly allocated, including 5 rats to a blank group, 5 rats to a sham operation group, 25 rats to a model group and 25 rats to a fire needling group. The model and fire needling groups of rats were again separately divided into 1 d, 3 d, 7 d, 10 d and 14 d groups. A model was made using modified Allen's method in the model and fire needling groups. The BBB score was recorded and the expressions of Wnt andβ-catenin genes were determined in every group.Results In the model and fire needling groups, the BBB scores were significantly higher at 7 and 10 days than at the previous time point and there was a statistically significant difference (P<0.05). The BBB score at every time point after treatment was significantly higher in the fire needling group than in the model group and there was a statistically significant difference (P<0.05). Wnt3a gene expressions increased in the model and fire needling groups at 7 and 10 days compare with the previous time point (P<0.05). At 7 and 10 days, Wnt3a gene expression was higher in the fire needling group than in the model group and there was a statistically significant difference (P<0.05). The changing tendency ofβ-catenin gene expression levels was basically the same as that of Wnt3a's.Conclusion Fire needling can modulate the expressions of Wnt3a andβ-catenin genes in neural stem cells in spinal cord injury.

OBJECTIVETo improve the surgery results and living quality of patients following the operation of the combined approach of tympanoplasty and mastoidectomy with close technique.
METHODSThe clinical data and following-up results of 49 patients treated with combined approach of tympanoplasty and mastoidectomy with close technique and 82 patients treated with open mastoidectomy with tympanoplasty were retrospective analyzed.
RESULTSIn the group treated with combined approach tympanoplasty, all patients got dry ear in 20 days and 31 patients' hearing level enhanced over 15 dB after the operation; but in the group treated with open mastoidectomy with tympanoplasty, only 13 patients got dry ear in 20 days and no patients' hearing level enhance over 15 dB after the operation. Although the recurrence rates between two groups were not significant difference, the patients of former group not only took a shorter recovery time and got a better hearing recovery, but also kept a normal external auditory meatus, at the same time, they need not to clear scab at fixed period all life long.
CONCLUSIONSWhen performed on carefully selected patients, combined approach tympanoplasty was a feasible surgical method to improve the surgery results and living quality of patients following the operation, however, the advanced equipment and perfect operation skill are necessary.
